Thanks for that, can you reference with a picture of the other 2 caps by the PSU that need replacing? The board I got has only 1 capacitor next to the power connector, this one is 10v 3300uf. There's another space for another capactior next to it but this is blank (nothing was fitted).

1.2 Motherboard, have upgraded the ram on it and tsop flashed IND bio. Works fine but 3 caps by the CPU heat sink look bad and want to replace them. Anyone knows the exact part number or values for the 3 pictured caps? Thanks

Just posted some pics

I doubt its the bios file, cause the same thing is happening when trying to flash the Net

Here are some pics of the points, I'm sure its not the points. I redid them at least twice and also tested with multimeter between all the points and there's continuity.

Anyone been able to use the app for the diymore Lattice USB Download Programmer on Windows 10 and are there drivers for x64? The only file pack I found and downloaded, is unable to install the drivers, If I try to update manually through device manager it says drivers found but they maybe currept and unable to install.

XBOX 1.4 board, ST bios chip. Bridged the usual two points. HDD was dead, so installed Jafar chip and tried to lock another HDD but failed. So booted IND bios from Jafar, run Hexen 2021 and tried to flash onboard bios. It seemed to work but when rebooted the console it still had the stock bios. Tried another HDD which managed to lock to the board using Xblast by booting from Jafar, booted Hexen disc from the soft modded HDD and tried to flash bios but gets stuck trying to erase the bios and nothing happens. Rebooted, then ran xblast OS from the hexen disc and tried Net Flash but again gets stuck. Redid the two boints on the board and re-checked, they're defenitly bridged. At this point I'm at a loss to why it won't flash the bios. Board has some signs of corresion.

Resolved, the issue some how lays with the HDD. It won't allow me to copy any files onto C drive or c:\BIOS, no matter what I tried, even through FTP. It just creates the file with zero bytes. This is why the flashing through disc won't work, so I resorted to flashing through Net by booting XBlast OS. Probably could've done the same through Jafar as it boots into XBlast by default. After Net flash with IND 5003.67 it successfully boots into that each time with Jafar chip not connected, now I can proceed with Ram upgrade. Thanks for your help with this.

Thanks, I'll give it a try. Does the pack include IND 5003 bios? This is the one I want to flash as I intend to upgrade the ram on the board and want to use the IND bios. Also woud it matter if I flash 256k rather than 1mb file to it?

Its a 1.2 board with Winbond. I checked and there was a bios.bin file with size zero. I deleted it but still Hexen 2021 gets stuck copying files

After I locked the spare HDD I choose to boot from the onbaord bios before I attempted the flash. But even when I unplugged the jafar chip, booted from the stock bios with the new HDD locked, it won't flash the tsop. Update: So it looks like I was using a very old copy of Hexen and now I got Hexen 2021 but when I choose to flash winbond then choose IND 5003, it starts to copy the files but get stuck @ copying , please wait ...

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?

Figured it out, had to unlock the HDD onto the original motherboard it came from before locking to the other one so I know how it works now. After I got it flashed, I unlocked so the HDD is unlocked ready to use on any other board. Thanks again for the great tip.

Just to be clear, I need to get a spare xbox HDD, unlock that on its original motherboard then use it with the other motherboard that has the faulty HDD and lock the drive to it?

I've got a USB lpc flasher which you kindly linked me to before off ebay and that is working well with most of the ST chips I've come across. Can you recommend or link to any JTAG programmers that can do the job of writing svf files or reading of IC? Thanks

So I received this in the post today, to me it looks like a re-design of the Aladding XT. 1mb chip with X2 512k bios, xblas & IND 256k bios each. I've seen several posts and links here before to other forums about re-programming the IC on Aladding XT but no exact step by step guide. And recently someone else did it on discord and I reaced out to them but they never shared how they did it. I got a faulty Aladding XT which was working fine and had the chip on it flashed with Xblast bios for testing while doing ram upgrades until one day it went bad after an attempt and since then it just frags whenever its installed on any board. I know its not the ST chip as I re-programmed it and tried different ones but it just does the same which could only mean the IC gone bad or curruept on it. I've got several devices that could program the xsv files format like NAND-X, Glitch360 Spi & Matrix NAND programmer. anyone used or has idea how any of these can be used to program the IC on Aladdin XT or read the IC on this new Jafar chip?

Nice one Dave, this is certainely an easier fix than trying to dump the eeprom. I'll give that a go

So I tried with adapter both sides, with XBOX plugged/unplugged with xbox on and off but won't detect or read EEPROM. I know the programmer is fine as it reads/writes other chips. Any ideas!!!

No I didn't power the XBOX but the programmer supplies 3.3 by default or 5v using an add on adapter.

So had 4 xbox's sat in my room off ebay that I wanted to do ram upgrade on, booted one which greeted me with blue xbox logo and xecutor 2 at the bottom of the screen before loading what seemed be original dash. Opened it up and found a SST49LF002A chip hard wired onto the LPC port using enamled/magnet wire.

I tried with CH341A USB programmer to read the SPI using 8 pin clip but i just couldn't get it to detect or read the eeprom. I've got another 2 try still

I've got couple of eprom programmers/readers. You got more details or guide on this?

Thanks, I'll try that the next time. Gone through like 8 hard drives and gave up. Then going through more stuff to throw out found another HDD, tried it and it booted to dash. Just done the soft mod and its a 1.1, doing a ram upgrade on.

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?

Update: @KaosEngineerusing the copy /b crcwell.bin+crcwell.bin+crcwell.bin+crcwell.bin crcwell1MB.bin you suggested has worked. I wrote the new 1MB bios to the SST49LF080A and the xbox booted XBlast OS. I'm also able to program the SST49LF002A with any 256kb bios and boot this successfully. This NANO USB Programmer is really handy thing and nice to have. @Donnie-Burgeryou should give it a try. NANO USB Programmer for PC M/B BIOS repairing with Economic shipping.
