Hi,

i Was lucky enough and get free Xbox Classic. 

Xbox was manufactured in 2003.

During the disassembly i found out that console got modchip, could you help me determine which one modchip is it (see attached)? I did some digging and probably the chip that is installed is Aladdin, and it should start after holding power button for about 1s, but nothing happens after that, just MS Bios starting.

I've checked if the wires are still soldered and they hold well. Also found out that there is a leak from capacitor - probably the what that is used to hold the clock. I found information that it can be removed.

Please share yours knowledge with me ;)

It's one of the many Aladdin modchips.

For modded operation, hold the power button for longer than 1 second to enable the modchip.  

For stock operation, power on the console with a short tap of the power button.

 

Edit: Where's the wire soldered to the modchip's D0 pad go? 

It must be connected to the D0 point on the motherboard for the modchip's BIOS to be loaded when the power button is held for longer than 1 second.

If the stock MS dashboard loads after powering on the console with a long power button press, a replacement dashboard may not be installed on the hard drive.  Installing a modchip is one part of the modding process.  Installation of a replacement dashboard is the next step. 

When powered on with the modchip enabled, is there an Evox shield displayed in the upper left-hand corner of the screen?

Is text other than Microsoft printed below the big X logo at the end of the startup animation?

 

Next, perform the following steps to see if a modified Xbox BIOS is booting:

1. Power on the console with a short power button tap.

2. Go to Settings > System Info.  Wait for the end of the scroller before it repeats. Does it have a D and K line?  If so, what are the values displayed for each?

3. Power off the console but this time power it on with a long power button press.  Repeat step 2.

No, there is no Evox shield displayed in left-hand corner.

And there is only Microsoft printed.

 

Attached are SS from normal power on and long power button press, both have the same values if it's about D and K lines.

 

Today during long power button press something weird happend. Xbox started, I could hear that disc drive is working and FAN, button there was no screen and no sound.

Have you tried to load a install DVD in the DVD drive and power off then on the Xbox with a long press (2 to 5 seconds) of the power button?

It's sounding like the modchip is not activating .

There is some solder joint I would redo as to me they look suspect, It's mainly the bottom two in the black circles but I would at least resolder the three that I have circled.

Hi,

Sorry for late response, in mean while I've ordered new Aladdin modchip from AliExpress. After soldering It to motherboard and holding power button for about 1 sec, Evox logo appeared in upper left corner of the screen. I also tried to resolder old chip, but without success. Most likely the old one is dead.

 

My question now is, how to install custom dashboard, homebrew etc. It's possible to somehow put some data over FTP, or do I need burn DVD with some files?

Installation of a replacement dashboard is usually done with a burned DVD disc that you boot (e.g., OGXbox Installer 2021 v1.5.3).

You have to have a replacement dashboard running before you can FTP to the console.  

Once the console boots a modified BIOS to allow unsigned code to run, the installer disc provides the user with a menu to install replacement dashboard(s) and other applications by copying the files from the DVD to the hard drive.

Don't know why, but I can't boot OGBox installer. I'm using DVD-RW and burn speed of 2x or 4x, but always get this message that disc cannot be read or it's format is wrong. Ofc original games booting fine, I've tried also burn a game and run it, but got the same error message....

Any idea?

Try DVD-R media.  They seem to work best for me across all of the different Xbox DVD drives even though the table below indicates that DVD-RW works well too.

Which brand/model of DVD drive is in your Xbox?

It's rare for Xbox DVD drive to read a DVD-rw you really need to use a brand name DVD-r (I use Verbatim DVD-r) and write it as slow as possible.

The other option is you can use a PC DVD drive to read burnt disk like the installer disk.

What do you mean by:

"The other option is you can use a PC DVD drive to read burnt disk like the installer disk."

As long as the Xbox is hard modded (Mod chip or had the onboard bios re-flashed ) you can temporary fit  PC DVD drive to load the installer disk and setup the new HDD.

When I tested using  PC DVD I left the yellow power led connected to the original DVD drive and used a 4 pin Molex power splitter to power the PC DVD, I have tested a sata DVD drive using  sata2ide adaptor set to slave and a 80 way IDE lead as well.

The PC DVD drive can not read an original game disk unless it has had the firmware on the DVD drive re-flashed.

      Hello Everyone. 
      I am kind of new/kind of old to the scene, as I have an rev 1.6 Xbox that I bought brand new in 2006, softmodded and installed a 160gb harddrive, which is(was?) limited to 137Gb useable space, copied all my bought games to it, threw in a couple emulators, and then just used it on and off and basically forgot anything involved in the process to the mists of time. 
      Recently it wouldn't power on, so I replaced the common 5 3300uF caps that were leaking, and it was good to go. My brain noted that the 16 year old IDE hard drive will not run forever, and I should look at upgrading to a SATA configuration.
      Due to the time gap, very old versions of software, I have now read so much conflicting information at this point am not sure what to do in 2021.
      I  no longer have the original drive. I don't appear to have an image of either drive (8gb or 160gb) in any of my backups either. My fuzzy memory says this is bad because of linked keys. 
      I do not have a PATA usb adaptor, or computer with PATA. I have an Xbox to USB adaptor, but I don't think I have a compatible thumb drive. Based on my research I've ordered the "correct" Startech SATA/PATA adaptor. The existing drive already has an 80 pin cable. 
      I do have ftp access without issue. 
      I'm attaching a 2 screenshots of my drive/system info, my questions are:
      Is that key in the screenshot all I need? If not what is the best way to go about backing up the drive/board key "Just in case" things go bad.
      And is Chimp (https://www.reddit.com/r/originalxbox/wiki/chimp/)  still the best way to clone it to a new drive in 2021? 
      I undoubtedly will have more questions, but backing up is my first priority, and once I have a confirmed backup I will be much more comfortable playing with it, and hopefully updating the various software I have loaded.  
      Any "critical hints" or gotchas would be appreciated as well.

      hey, im a bit of a newb when it comes to og xbox, but i just bought one for the first time off of ebay. it works great, but i know its a big deal to remove the clock capacitor. it looks like it may have been opened before but i dont have a torx screwdriver to open it up to check. im going to my uncle's on saturday so he can open it up and see. is it fine if i play it with the possibility the clock cap hasnt been removed? it works great in every other regard.

      I have this 1.4 Xbox that I've been tinkering with trying to being it back to life.  I have plenty of other MBs so this has been more of a journey project more than the need to have a working board.
      The board initially would flash red.
      I took out the eeprom and it wouldn't read stable.  I replaced it with a new chip and flashed it with a few different images finally settling on an image of another 1.4 that works.
      It now boots to a black image with a solid green light no fraging.
      So I ripped out the tsop and it also is awful, it has a few hundred unstable bits.  So I decided to just install a modchip.  Installed an openxenium and was able to boot into xeniumos!  There was horrible diagonal lines that looked like interferance that would progressively get worse until there was major graphical glitches.  I saw power issues could cause problems so I replaced the power caps below the CPU.  Problem persisted.  Replaced the powersupply, everything looks clean. 
      Flashed M8+ onto the Modchip go to load it and the screen goes blank.  
      Any ideas for things to try would be appreciated.
       
      Thank you
