In practice, some have tried flashing the 1MB TSOP of my Xbox 1.1 Softmodded with an original MS 5530 bios. The TSOP writing ended with a succulent but I do not know why the Xbox did not light up anymore. Maybe the bios was not compatible with the version of my xbox, or the TSOP was completely erased. At that time I tried to retrieve the tsop with a D6_TSOP_BIOS using a Duox2 GS Cromwell Modchip. I have tried many times to start the console with that bios to try to rewrite the TSOP but unnecessarily because it was not possible to recognize or write the TSOP. (I opened the console and soldered all the points, and then cut them at the right time) What I wanted to ask you, if the M7_TSOP_BIOS you did, change something in terms of functionality, or is it the same as the D6 TSOP? I ask you why I do not want to waste time getting rid of the console and doing dozens of attempts. Last question, MORE IMPORTANT, can you recover a completely deleted TSOP, or completely rewritten with an incompatible bios?
You can recover from either of those two. However, one method involves removing the TSOP flash memory chip from the motherboard and reprogramming it with an external programmer. What brand of TSOP flash memory chip is on your Xbox motherboard? ST, WinBond, Sharp, Hynix, etc. I know that bennydiamond's XBlast Lite modchip has the ability to flash the TSOP using his XBlastOS (BIOS) like the Chameleon modchip with the special d7_evox BIOS. Another possible method found posted at another website's forum: Heimdall found his notes and posted more about using the D6_TSOP Evox BIOS and the 3-wire trick. Read his post HERE!
The "3 wire" trick with the 1.0 1mb tsop is as about as old as xbox tsop flashing. But it's only if the flash fails less than 75% or you didnt resize the bios. Wrong bios or what ever won't be fixed by it, you need at least one bank with a working bios on it. The modchip method may well work though
Removing/unsoldering the chip, programming on an external programmer and installing a TSOP 40 pin socket will work (socket not required; solder programmed chip back in place). Like 'bunnie' did over a decade ago. Seemed like the BIOS flashed may have been only a 256KB bin file not the entire 1MB of the 1.1's TSOP chip and the software didn't resize automatically to fit. Not sure what software was used. I might have skipped that fact if stated in the original post. More than likely the wrong version of BIOS was flashed to the TSOP: Table 3.5 BIOS Kernel Versions Xbox Revision / Kernel Version(s) 1.0 / 3944,4034,4036,4134*,4627 1.1 / 4817,4972 1.2–1.5 / 5101,5530*,5713 1.6 / 5838 Source: http://www.informit.com/articles/article.aspx?p=367210&seqNum=2 and * http://xboxdevwiki.net/BIOS
Fitting a tsop 48 socket is much more difficult than pretty much every other way of fixing it. Plus, you need a working tsop to boot from in the first place.
There is ST 1MB (CODE: ST-M29F080A) TSOP on my Xbox motherboard. Is there any chance of recovery? Could you point me to the guides and the latest methods to recover the TSOP?
Here is the video I did during the time I tried to retrieve the TSOp, and a thread from another forum where at that time I tried to ask for help if someone could help: http://theisozone.com/forum/viewtopic.php?f=35&t=27702
What size was the BIOS.BIN file? which BIOS? After the DVD (eurasia flash) booted (Linux printed), did you pull the modchip off the LPC header?
Here's the thread bennydiamond started - 1.0-1.5 TSOP recover BIOS: tsop_m7.bin https://assemblergames.com/threads/1-0-1-5-tsop-recover-bios-tsop_m7-bin.54493/ He describes how to use this bios to fix a bad TSOP flash for v1.0 - v1.5 Xboxes as the d6_tsop.bin BIOS would only work on v1.0-1.? (?=3 I think).
Many years have passed, I do not remember exactly, I tried with different modified bios files. I remember having them fit into a 1MB bios.bin file. Yes, at every attempt I pulled the modchip off the LPC header.
