This is the bottom side of motherboard Connect the two solder pads at R7R3 as in photo above. All Ver 1.0/1.1 Xbox's with a 'SHARP' TSOP chip must also connect the additional red wire as in the photo above. All other TSOP's DO NOT require this step. TSOP Unlock points for all Versions 1.2/1.3/1.4/1.5/ Xbox's This is the top side of the motherboard These Xbox's have both points located on the top of the motherboard, for the first point connect the two solder pads at R7D10 as in photo above. For the second point locate the junction between R7D2 and R7D1 and connect the two solder pads as in the photo above. After the solder points are completed you should re-assemble your xbox (but leave the top cover off) when the power button is pressed it should boot normally as it did before you started. Note if you get the message TSOP write protected while attempting to Flash the TSOP you might need to check and resolder the points to ensure a good connection was m while attempting to Flash the TSOP you might need to check and resolder the points to ensure a good connection was made. To split Split a 1MB TSOP (v1.0, v1.1) into 4 banks of 256k, the following picture explains how to accomplish this: Note: If you have a 1.6/1.6b Xbox, it has no TSOP and therefore you cannot flash it. You will have to install a modchip or softmod.

Hello people. i managed to fix the traces and install the xecuter2 modchip which i had spare. switched it on with the switches in correct position and im getting a bios flash screen. now the funny thing is now. when i switch the chip off via the switch. i fort it would boot into the ms dash board. which it dosent. the console switches on but nothing comes on the screen. so now the flashing. i dont have no blank dvds to install the bios. only way is to ftp into the console. i did try and quickly ftp into it using a normal ethernet cable plugged in to my network splitter but it wont connect. do i need a user name and password. been so many year i cant even remember is this chip working properly well atleast is it supossed to be doing what its doing cheers people

Requirements.Working Xbox with a Pinheader Install and a Working Modchip with a Hacked BiosHackDaBox Re-Flash DiscWith the working Xbox turned off Remove the lid , the screws from the hard drive bay and DVD-ROM drive. Remove the hard drive (still connected ), lift it up and over slightly, now lift the DVD-ROM drive up ( still connected) and spin it around to face the opposite way. So now the DVD-ROM is facing the wrong way round but still connected . Support the DVD with something underneath, so it sits level. Now put the hard drive bay back where it used to be ( covering up the power supply ).WARNING NEVER TOUCH THE POWER SUPPLY AREA AS IT CAN KILL YOU !This procedure is safe the way I have described above because you have access to the Modchip area . The chip should be plugged onto a pinheader ? If not you can not re-flash this way.Now remove the wire that goes to the D0 pad on the Modchip itself. Unscrew the screw near the LPC area and put the D0 wire under the screw and carefully tighten it up. You can solder the wire to the circle around the screw if you wish. remove any wire you have connecting the chip to the Xbox motherboard but leave the chip plugged into the pinheader.Now depending on your chip type you need to make the chip enabled all the time.On DuoX 2 solder a wire between the BT pad on the chip and pin 9 on the chip (This is point G on the official Duo diagram) see the picture below coutesy of cubistproject.On Aladdin solder a wire between BT pad on the chip and Pin 2 on the chipOn Spiderchip simply leave off the switch.Note : You need to do this to the good chip in the Xbox and the ones you intend to Flash.Turn on the Xbox with the good chip in and let it boot up and then load HackDaBox Re-flash Disc Choose Re-flash Spiderchip ( it works fine on DuoX 2 and Aladdin ). Choose the Xbox version you wish to use the flashed chip on. E.g. 1.0 - 1.5 or V. 1.6 but don't hit A to flash yet.Note Evoxdash or Slayers or your preffered Flash utility can be used with this method.Now carefully pull the Modchip off the pin header with the power still on ( note only 3.3 volts goes into the Modchip so it will not electrocute you.Now carefully line up the chip you are going to flash and then push it on the pinheader. Never try and force it on , double check it's lined up properly and it should slide onto the pinheader easily.Now go ahead and flash the chip now. The Xbox should turn off after the successful flash. Once it turns off ,turn it back on and the previously bad flashed chip should now boot the new flashed bios that you just put on it.If you picked Xbox V.1.6 and your Modchip is not in a V.1.6 it may not boot reliably so try it in the V.1.6 box.Remember to put all the original wires back to the chip, and remove any links you have made. In other words put the install back to the manufacturers recommendation.

Just looked out one of my old original xboxes, It has an Aladdin EX chip like one in picture..The xbox is a 1.6 and only has a 40gb drive and was going to upgrade it to a 250gb drive that I have... So I tried to flash with EvoxM8+ v1.6 BIOS which I ran through evtool to enable LBA48 support. But when I tried to flash it to Aladdin EX it just sticks on erasing as seen in picture. I have tried holding power for 1 second write to chip not enabled,tried 2 seconds same result, tried more than 5 seconds same result...So I take it that chip bios is not writeable. Do I need to flash it with an external device / EEPROM programmer. Or if I take out the SST 49LF002B chip from Aladdin and replace it with SST 49LF020A will I then be able to flash it...

So I just finished another successful TSOP flash on a v1.1 and wishing I had spent more time focusing on that vs. having to repair numerous LPC ports from teaching myself to solder. Oh well, I digress… Since I’m fairly new to flashing bios’s (Xbox) I’ve been reading up on which bios is best for my needs as well as the method of flashing. Since I’m pretty old school I was always taught the importance of having a good boot up disc (ie. Hexen) laying around. Kinda fancy since I grew up thinking we’d be booting everything off floppy disks forever! The more I’ve read I’m finding that maybe Hexen isn’t the most impervious or bulletproof solution out there. It would appear that the Hexen-based bios’s could be tainted in a sense (as well as limited in variety). Can someone verify if I’m understanding this correctly? I hear those particular bios files have been pre-configured and therefore not the best choice to flash and replace the old soft mod. I’m of the impression that the most bulletproof method would be hooking up the hard drive to my computer and/or FTP’ing the OGXbox Installer onto it. Anyone? Lastly, please correct me if I’m wrong, but I’m thinking that it would be silly to use any of these older BIOS’s without any LBA support. I’d like to utilize one of the newer (but not entirely necessary) Titan or Cerbios revisions available. I’d love to hear what you guys have to say about this. Thanks in advance for your feedback ✌

I was playing with a different 007 Agent Under Fire game save hack and while flashing a new BIOS on a version 1.0 Xbox I flashed a 256k BIOS(STUPID I know). Yep it was FRAGing afterwards now you can either fit a mod chip and be done with it or do a 3 wire flash recovery by following the instructions that can be found by working the Google on the interweb. The instructions say 1 wire soldered to ground and the other 2 get soldered to points on the bottom of the mother board(pain in the butt as you now have to remove the PCB again), Me been lazy and not wanting to remove the PCB again found an easy way to do the 3 wire trick. {pic 1} You need a test lead with alligator clips both ends and a pin. {pic 2} Clip the pin in one end and the other on the metal shield(you did leave the metal shield in didn't you)and the point of the pin is gently held on pin 1 and 2 of the TSOP chip. {pic 3} Power on the Xbox and if all goes well your Xbox boots. Remove the pin that's shorting the 2 pins to ground. Now flash the correct 1024k (1 meg) BIOS. If you don't like the idea of shorting the pins on the TSOP IC the points in the pic below show the same points on the top of the PCB and the bottom of the PCB. {pic 4} 1 2 3 4 Inside the box on lower right of pic 4 are the same points as in pic 1 On side note I did try a mod chip and with some BIOS's the Xbox booted but with no video out but the Xbox was still showing on my home network and I was still able to network in to the box. SS Dave Those who can hard-mod, Those who can’t soft-mod. Ps If you like it don't forget to say thanks and please give me any feedback good or bad!

Hi; So I tried to flash my tsop xbox 1.1 using the latest 2.02r UDMA5 version on a 3tb WD black. My XBOX was previously running EvoX after it finished flash the xbox led now flashes red and green. Could someone please assist.

Hello all! I have a little question. Can I use 49lf080 to make cheapmod? I have one OGX v1.4 intended for experimental purposes (in poor visual condition). I'd like to replicate a dev-kit with COMPLEX_4627debug and dev dash. or if you know other cheap way to get 1MB flash at v1.4, please give me a hint. Best Regards, PatriX1234

Evening everyone. Tried to post this on /OriginalXbox and for some reason my post isn't going up even though I've been active in it for sometime now. Anyway here is what I am trying to do: Hey fam! I have a 6 Xboxes. 3 are 1.0 and all have chips. 2 Jafars, one x2.0 pro. Most had issues one way or another and I had the chips lying around anyway. So out of convenience at the time, I installed them. I figure I don't need them in there. I already understand the "if it ain't broke, don't fix it." I just want the chips for other boxes. Definitely not new to the OG, I've just never swapped mods other than chips. I have TSOP'd before, so bridging points is not a problem. I am just trying to figure out steps. These are my thoughts: Drives are all unlocked (partitioned, formatted, no retail/stock dash), so I am thinking pull the drives, rebuild to stock with FatXplorer, install the drive back in the box, then relock with the modchip still in. Pull the modchip and disconnect d0 Bridge points Boot from exploitable game Use SweetDarkDestiny's TSOP MC Flash Program or his flasher disc Profit? Just looking to see if anyone has done something similar and if this process sounds like it will work? Looking for any and all input other than "don't do it." If I mess up, I still have the chips right?

Bought of ebay with error 7 (faulty HDD). Installed Jafar modchip, connected unlocked HDD and locked to it, boots into xdash from previous install with soft mod. Soldered both points on board and even tested with multimeter which confirmed bridged, load up hexen and choose tstop winbond, loads Gentoox and selected HDD flash, soon I hit flash bios console turns off and reboot! Any idea to what's wrong here?

I have a modchip - currently unknown, I did it 10 years ago... Considering simplifying things and doing a tsop flash instead. So I know that the mod disables the onboard tsop (d0) so without enabling the chip, and disabling the mod, I cant access the tsop. But with the mod disabled, I cant boot unsigned, and therefore none of the flashing tools. So, am I correct is saying that once the mod is removed, I will need to soft mod, then flash? Is there another way? Switch on the d0 line maybe? boot to flasher, unplug mod (pin header install, and disconnect d0. is that even possible? Open to suggestions... Or.. I could just leave it alone...

Was doing a clear out and find an board under my desk that still boots but I'm missing the original HDD. I tried all the HDD's I got but they all gave error code 6 which I understands the board was unable to unlock the HDD. I've Aladding XT and Open xenium chips, can I install either to get around the HDD and flash the tsop or its never gonna happen without the orignal HDD?

Hi, a few months ago I bought 2 Xboxes to repair. I was happy to find out that one of them had a xt plus chip installed. I have tried flashing evo m8+ to the chip through hexen, unleashed x and xblast (ftp). Xblast got me as far as letting me confirm the flash by letting me press the required button combination. However it stated that the changes were not made and put be directly back to selecting the bios I wanted to use in order to flash the chip. I found online that this usually happens when the soldering of the has not been done correctly. Previously I have opened the Xbox in order to clean it, apply new thermal paste and recap the console. While I was doing this I saw that the xt plus was installed in a different manner as what I have seen previously. Could this be the reason why I am not able to re-flash the chip? I was thinking on desoldering the chip and installing it so it can be plugged in the pin header as normally. Could this solve the issue. I am quite new to modding Xboxes but so any advise would be great.

Reposted with pics on Imgur: https://imgur.com/gallery/rH19myY I need help flashing this corrupt Bios chip on my Og Xbox. Unfortunately this is the only way i can reflash it, as i attempted to flash it but forgot to bridge the points now my Og Xbox only works with a modchip. I got around to picking up a programmer TL866II Plus with Xgpro v11.90 Flasher tool. But i keep getting a pin detect error. I first tried it with a new exact replacement chip using a TSOP 40 adaptor. Then ended up losing that chip. And desoldered the one from the motherboard. I also removed the cold solder from the adaptors and added some fresh new high quality solder with flux to make sure that isn’t the problem. I socketed it into the slot and no luck “Pin detect error”. I then ordered another adaptor this time without a socket and i soldered on the bios chip. I also redid the solder joints, as the ones on that adaptor were dull aswell, and no luck. I picked up the correct or the closest settings on the Xgpro v11.90 software. I tried TSOP 40 Hyundai and Hynix HY29F080 with no luck. It yet again gives me a “Pin detect error”. I even tried auto detect and it says chip not supported. On the chip it says Hyundai HY29F080T-90, but i can’t find that exact model number on the menu. Could that be the issue or is it something else. I have no idea as this is my first time using a programmer. And saw a video or two on how to use it.

Hi I have been trying this for a few days and nothing. I used to have a softmod, but wish to install cerbios to my TSOP. I put in a new 3tb drive that i set up with fatxplorer. I installed the bootanimations folder to c drive, placed the cerbios.ini on the c drive also, and placed the bios in a folder named Bios on c. I loaded the hexen disc and bios checker they still work fine. I have an ST chip, and joined the connections fine, as I used to run the softmod and hexen still loads. If I use XblastOS (tried from hard drive and from some Xbox flash programs that run off disc) to flash, if I pick net flash I upload the bios and it does nothing on the xbox. I tried a 256k, 512 and 1mb version of cerbios. If i put the files on the drive and select HDD it finds the bios, I get a message about holding LT+RT+START+WHITE to start the process, is not easy but when it works it just goes back to the bios select screen. If I try gentoox from any loader disc, the program loads but then come up about invalid boot disc and shuts the xbox down. I have not found a gentoox to run from hdd yet. I have tried a few times now and nothing, was able to install some dashboards, but just having trouble flashing the tsop. I can not find an OpenXemium to buy that is not used or expensive, and all the aladin ones seem to be unflashable now. Anybody got any ideas of what I may be doing wriong, or suggest a dashboard I may be able to flash cerbios to the tsop, current cerbios is 2.0.2. Thanks for any assidtance you may be able to offer.

Hi all. Soldered the points required. Ran Bios Checker v5, saw the Winbond. Using Resctoox to flash the bios, when it locked up. It locked up before I even saw the bar. My Xbox will boot, but now the Bios Checker says unknown mod chip ect. I pulled the board as I thought maybe my solder skills weren't what I thought they were. I was able to check continuity on both sides of the and got tone from both sets. Any thoughts at all? This box is softmodded. Ready to pull my hair out. Thanks for any input

Help flashed bios to a 1.6 xbox which has xecuter2.6 chip using slayers installer disc. Tried to flash to bank 1 which seemed to be empty as when I tried to boot from it just got blank screen... Any way after flashing bios from slayers installer disc which seemed to go well it said xbox will shut down...Then when I tried to boot from bank 1 just get red ring and nothing on screen.tried from bank 2 and get the same red ring,then tried dissabling chip and boot to ms dash but still just get red ringso can not even do softmod and update again that way... any way back? could xecuter 2.6 modchip be taken out and reflashed from pc?

Hi, i'm new to the scene and got my first chipped box a few weeks ago. Because i'm interested in tinkering around it happend that my Flashchip somehow got corrupted in the process of trying out another BIOS ... i'm kinda stuck now and absolutely want to recover from this situation by myself, so there have a few ideas risen and i may ask more veteran people about them: Ideas: 1. Boot the XBox of a friend of mine, remove the Flash with power on and flash mine. Did this years ago regulary on PC Mainboards but also know that these devices aren't built for hotswapping them and so i'm a little bit afraid of killing the circuitry with voltage spikes. 2. Softmod the Box and Flash the Modchip then. Question 1: Possible in general? Question 2: Is it possible to Softmod "externally" on a PC. I have a eeprom backup of my box and the key isn't nulled. 3. Invest a few bucks and buy a USB Flasher which is compatible with PLCC32 chips - mine is a SST 49lf020a. Question: Can i use other Chips with similar specification too? I'm thinking of ordering a SST 39SF02070-4C-N which has very similar specifications compared to the original one, which is no longer produced or available. Just a sidenote: The Modchip i use is a Alladin XT Thanks, Egon

Hi i have a Xbox 1.0 with a corrupt bios and i discovered that the TSOP mod wasn’t done before i flashed it and ended up corrupting the bios. I tried the 3 wire trick and that didn’t work and can’t seem to find any bios reflash settings on the Open Xenium mod chip. So that really only leaves me with flashing a new chip and soldering it in. Is that the only option i have?

Hi all, I've been out of the scene for ages, but recently saved a few xboxen from clock cap death and bought some aladdin chips to mod them with. Also got some SATA to PATA converters, which I haven't gotten working: proper 2 cap version with the master / slave jumper and an 80-pin cable, seems to cause a conflict with the DVD drive in every config I can think of - OGXBOX DVD shows "linux" and then DVD keep seeking back and forth forever. I thought I'd update the bios to see if that helped. I've gone through as many threads related to this topic as I can e.g. https://www.ogxbox.com/forums/index.php?/topic/3866-aladdin-flash-not-writable/ and tried the suggested solutions, but I am unable to flash a new bios to my modchip. I' going to try and provide as much information as possible as well as the things I've tried, in the hope that someone can assist. Top side of the board (this is one I haven't installed, installed one is identical with BT and D0 connected correctly, chip boots fine): Bottom side of the board: Stuck on erasing (and bios ID): Bios hashes: I'm using OGXBOX Installer 2021 DVD. Xbox is reported as 1.4. So I've tried the following: xflash for sst49fl020: seems to be able to dump the flash, but fails on flash with an "Flash check id failed, are you sure you have flash enabled?" XBlast 0.56: select evoxm8_67. when I press both triggers, start and white, the xbox reboots (wtf?) OGXBOX menu flash: gets stuck on erase as per the image above Tried the short and long power button presses, doesn't seem to change anything. "Chip: Protected" appears on the OGXBOX screen Any suggestions? I do have a minipro programmer somewhere with (I think) the correct adapter so could try that as last resort. Thanks -j

Hello, I'm looking to Recover a bad Tsop Flash on a 1.4 board. I have an Aladdin XT on the way which will be my 3rd chip install. Been looking around and have a few questions. First, I understand being able to disconnect the D0 wire once booted with the chip would give me the option to tsop using Xblastos. My question comes from something else I'm looking into Eeprom recovery using a raspberry Pi, It accesses the I2C connection and pulls the Eeprom. Could I use the Pi and an LPC pinheader to reflash the original bios via tsop in a similar method?

So yesterday i decided to flash a new bios to my V1.1 Xbox Modchip Super Aladdin with the SST49LF020 to remove de DVD drive check and used EVtool to edit a EvoX M8+ 256K Bios, but me being stupid i also decided to change the EvoX logo to be sure the Bios was indeed changed, big mistake. The flashing completed, the Xbox turned off and now when i press for 1 second to activate the chip i get no signal from the TV, no animation, no sound nothing. I even put Hexen 2018 but nothing, it's dead. But it boot to the stock dashboard with a quick press. I've been searching for hours, but still have some questions: 1) If i buy one of those Aladdin XT PLUS2 XT+4032 that come with a SST49LF020A can i just replace that with mine and it will work? I saw that it comes pre-flashed with a EvoX M8 bios? 2) Do you know were to buy just the SST49LF020 with the Bios? I feel very sad about this, because i treasure my consoles and this was my main and first Original Xbox and would like to restore it.

I grabbed a Kernel file from this page and I flashed it with XBlastOS. Does the kernel have to match the original kernel? What is the kernel relative to the BIOS? Normally kernel and BIOS are two very different components of a computer. I shouldn't have been able to flash the TSOP with the kernel correct? How are those kernels meant to be used? I was looking for the default BIOS. Thanks

I had xodus matrix on my ogxbox, and the original IDE HDD went bad, so I got my self 120gb SATA SSD harddrive, 80pin cable, IDE-SATA adapter. I decided to remove the chip when I removed the clock capacitor and reinstall it. I installed the new SATA HD with the adapter and I try to boot-up I don't get xodus matrix Bios at the bottom of the screen, and Hexen 2020 does not load. I am not sure if I need to re-program the chip and reload the Bios (which I no longer have) again. I still got the programmer board, and the loader winLPC tool...any advice what/where I get a BIOS to move forward and make sure it is not a modchip issue

Hello from France. first i have to say that i'm happy to see an active community around the OG Xbox. so i'm on a xbox period for learning hacking and i did a mistake on a v1.1 motherboard. i learned too late that 1.0 and 1.1 have 1Mo tsop size and i flashed manually with a 256ko custom ind-bios... i don't want to setup a modchip as i try to learn stuff. i really would like to recover the tsop bios. so right now, the xbox boot with no signal on TV, i hear hdd and dvd running, when i put hexen disk i can see led turning red as intended. i tried to split tsop into 2x512 and 4x256 banks, nothing works. i esitate to buy a xblast modchip as it worth around 25€... i heard about a 28/29 wires modchip tricks but i found no info about it. any other option i could try with my current stuff ? i have an x3 and aladdin modchip but i read i cant flash tsop from a modchip beside chameleon and xblast one. thanks in advance.
