vacatedboat Posted August 20, 2019 Report Share Posted August 20, 2019 This is my xbox 1.4v. I have 3 other boxes. I got very cavalier and loaded up truhexen 2019 disc to update the modchip bios. Of course I flashed the wrong bios. What i think may of been m8 for v1.6 boxes. It now turns on to ms dashboard but wont recognise the hexen disc anymore. As the chip is soldered to modchip guessing the hotswap or external re programming are out of the question. Is there any way to salvage this modchip? Is my only option is too remove modchip and softmod/tsop flash the xbox? Also to remove the modchip is it just the bt and do wires that need to be desoldered. Thanks for all help Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted August 21, 2019 Report Share Posted August 21, 2019 Flip the switch on the DuoX2 and boot the other bank. Not exactly sure which BIOS it may have on it. Generally, I always thought a v1.6 Xbox BIOS would boot on a 1.0-1.5 version, not recommended to leave it this way but reflash with a 1.0-1.5 BIOS. Booting to the MS dashboard indicates that your replacement dashboard is stored in a different location than the BIOS is attempting to load. The MS dashboard is the final dashboard attempted if all others in the boot order list fail Quote Link to comment Share on other sites More sharing options...
vacatedboat Posted August 21, 2019 Author Report Share Posted August 21, 2019 Thanks. I think i was using the eject button to turn on console sometimes not realising this disables the x2 modchip. Im worried flipping to the other bank may not have anything there. Like a black screen. I also found a dirt cheap aladdin xt plus. I could just put the wires onto it as the header pins are in place already. Will test tonight thanks. This is mostly for hobby fun.

SS_Dave Posted August 21, 2019 Report Share Posted August 21, 2019 It would not do any damage to the xbox trying the switch the other postion. If it boots with a purple shield in the top left thats a version 1.6 bios. Quote Link to comment Share on other sites More sharing options...
vacatedboat Posted August 21, 2019 Author Report Share Posted August 21, 2019 Just tested both banks. Looks like both are ruined as it goes down the boot order until the default ms dashboard. Will swap it out for the aladdin when it arrives Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 21, 2019 Report Share Posted August 21, 2019 Have you tried booting DVD Hexen or Slayers? SS Dave Quote Link to comment Share on other sites More sharing options...
vacatedboat Posted August 21, 2019 Author Report Share Posted August 21, 2019 Yes. My hexen disc no longer loads on either bank. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 21, 2019 Report Share Posted August 21, 2019 Bit odd to have both banks to stop I used to use a DUO X2 when playing with differant BIOS and if I flashed a dud BIOS I would flick the switch reboot and flip it back and try a differant BIOS. I always had a fallback bios that way. I also don't wire it to the power/eject button I link the BT point to the 3.3 volt pin that way it's allways enabled the only reason for wiring to one of the button's was to allow for XBOX LIVE.

vacatedboat Posted August 21, 2019 Author Report Share Posted August 21, 2019 Sorry. Didn't mention got this second hand. Is it worth changing the position of the BT wire to a 3.3v location. Is there one easy to locate on the motherboard/modchip itself bridging wire? Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 21, 2019 Report Share Posted August 21, 2019 Looking at down on the chip as it sits now. o D0 point o o m o o 3.3 Volt o o o d o - c o - h o o i p o BT Remove the wire from BT and add a link from BT to 3.3 volt If the Bt is low when powering up the xbox it disables the mod chip Are you sure it's not on a sccket as from new I sure they came with a pin header and socket. If that fails fit the new chip and start again. Quote Link to comment Share on other sites More sharing options...
vacatedboat Posted August 27, 2019 Author Report Share Posted August 27, 2019 Just an update. I managed to move the BT wire to the 3.3 v pad and bank 1 booted up with green logo and red evox shield in corner with custom bios. Bank 0 is just a black screen. So I plan to reflash bank 0 with another bios. Will take extra care. Any buos best suuted to the duo 2? Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 27, 2019 Report Share Posted August 27, 2019 Green logo with the sheild is a 1.6 bios but boot your flash disk on that one. Then load up the 512kb bios you want to flash to the other bank and when your just about to commit to the flash flick the switch the other bank then commit to the flashing the new BIOS.

KaosEngineer Posted August 27, 2019 Report Share Posted August 27, 2019 Which BIOS to use depends on your Xbox version more so than the modchip being used. Most BIOSes are 256KB in size. If the modchip has a 512KB bank size, the BIOS's dot bin file is written two (2) times consecutively to fill the bank size of the modchip. There are only a couple of BIOSes compatible with a 1.6 so you have a very short list to pick from. Older revisions have a much larger selection to use. V1.6 BIOSes M8plus_16.bin (Size: 256KB) x2_5035_v16plus_512k.bin (Size: 512KB) V1.0-1.4 BIOSes Size: 512KB x2_5035_vOld_512k.bin Size: 256KB M8plus.bin x2_4983.06_256k.bin x2_4983.67_256k.bin 4981.06_256k.bin 4891.67_256k.bin iND-BiOS.5003.06.bin iND-BiOS.5003.67.bin iND-BiOS.Beta.Feb-11-05.06.bin iND-BiOS.Beta.Feb-11-05.67.bin Quote Link to comment Share on other sites More sharing options...
vacatedboat Posted August 27, 2019 Author Report Share Posted August 27, 2019 Thanks. Its a 1.4v so i will pick from this list. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 27, 2019 Report Share Posted August 27, 2019 Thats a short list x2_5035_vOld_512.bin bios.bin Try this one if you like. SS dave Quote Link to comment Share on other sites More sharing options...

Those are the last or next to last BIOS versions released by the various development teams for the Xbox. There are many more earlier releases but it's best not to use any of them.

vacatedboat Posted August 31, 2019 Author Report Share Posted August 31, 2019 Looks like I jumped the gun. The modchip is a bit flaky. Its a clone modchip i guess not being AMd. It just boots to stock ms dash again. I took out the motherboard and checked the d0 (bottom of board) i also with xbox on carefully measured voltage at do and the bt. The d0 was 0V but bt was 3.7V. You can check the picture for any visable dry joints. My aladin xt plus turned up so might just pop that in instead. I can use the pin header and d0 wire already there. The bt wire needs to be connected to a ground pad according to a diagram i have. See how I go. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 31, 2019 Report Share Posted August 31, 2019 D0 is ment to read 0 volt with the chip enabled BT is now reading correct. Resolder all the pins on the conector and the main board Then clean the whole chip with isoproyl or metho and a tooth brush dry with a heat gun on llow temp or a hair drier. is the red light on or flashing?

vacatedboat Posted August 31, 2019 Author Report Share Posted August 31, 2019 The light hasn't been on very quite a few power ups. I may try cleaning it. I did switch to the aladin xt plus2. I cant get this to work either. The led lights red but on power up it whirrs a few times then powers up to frag. I think it might be the boards D0 solder point is bad. Its so small. While I had the board out I did the solder bridge for a future tsop if this drives me crazy. I have done 2 previous tsops on machines no problem but these modchips are a pain in the bottom. Will try to add some pictures later. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 31, 2019 Report Share Posted August 31, 2019 With the Aladin chip did you link the BT like this. When you can upload a pick of the solder and D0 point on the bottom. Quote Link to comment Share on other sites More sharing options...
vacatedboat Posted August 31, 2019 Author Report Share Posted August 31, 2019 Do and other solder points Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted August 31, 2019 Report Share Posted August 31, 2019 That looks ok If you test the D0 wire on the mod chip while it's not pluged on the board so the blue wire on the D0 point on the mod chip you should get a 1.8 volt spike on power up well I do with my fluke 87V in Hires mode.. Also with the chip is not pluged in do you get the Flubber boot screen? After looking at the 1st pic I would clean around where the clock was and look for damage there.

vacatedboat Posted August 31, 2019 Author Report Share Posted August 31, 2019 When the chip is out i alwasys get the green flubber stock dash and use normally. Will test voltage later. I will try to get a video up. Just need to compress it Quote Link to comment Share on other sites More sharing options...

vacatedboat Posted August 31, 2019 Author Report Share Posted August 31, 2019 I held the modchip in my hand on powerup. Testing voltages at D0 said 5volts and bt says 2.6volts. Not sure is that what your asking for. The D0 was wired into the motherboard. Quote Link to comment Share on other sites More sharing options...
