Possible? Use Tsop_m7 Bios To Recover Modchip

Dear, all Xbox fellow

I had a spiderchip since 14 years ago for my xbox, which is still working.

ABout 2 weeks ago, I wrongly flash 512kb bios into my xbox (1.1) TSOP (1mb), causing it unbootable.  I was trying to find a way to recover the TSOP, and one way was to use a modchip with special bios "tsop_m7.bin" for recovery.  So I did flash the spiderchip with tsop_m7.bin.  But I forgot my DVDROM is not working, so this method is not workable.  And eventually the TSOP issue was resolved with "3-wire trick". 

Now, the spiderchip is left useless without normal bios, and it seems the guaranty way for recovery is to use external programmer, which I don't have and don't know how to use.   There are some forums discussed quite good success of using modchip hotswap, and even Softmod to flash modchip (NOT TSOP).

So I decided to use most cheapest way - softmod - to recover my spiderchip.    But as my Xbox 1.1 mobo is soldered for TSOP flash,  I don't want to revert back to stock status.  I remember my cousin has a Xbox 1.5 (softmoded) which has not been used for long time.  Borrowed from him,  still can turn on,  BUT ERROR 07,   reconnect/changing IDE cable didn't work.   Changed to another HDD,  Error 06, obviously it should be the HDD issue.       My cousin doesn't have eeprom backup in PC, but he is quite sure it was backed up inside the 8G xbox HDD (WDC).   So I tried many times to do HDD hotswap connected to my laptop through USB-IDE cable and XboxHDM (Windows version),   no luck,   the Xbox HDD lock status is alwasy enabled.   NOT sure it is because of wrong timing or USB-IDE problem which may trigger the HDD to relock.

In actual fact, the easiest way to access locked xbox hdd is to use modchip,   but the spiderchip is useless with tsop_m7.bin bios inside.  Out of sudden, I was wondering,  Can this special bios be used to re-flash the modchip?

According to the steps in https://assemblergames.com/threads/1-0-1-5-tsop-recover-bios-tsop_m7-bin.54493/  ,     A15 & D0 need to be removed in sequence in order to activate TSOP,  but I am not aiming at TSOP,  so I don't remove the A15 & D0,   Should it work to re-flash the spiderchip?

 

Anyway, I have already tried last night,  and I am facing the problem to boot to the Orange Xbox logo (tsop_m7) on this Xbox v1.5.     Previously i had nearly no issue to get the orange xbox logo on my xbox v1.1. when chip-in with this spiderchip.      The v1.5 Xbox remains with black screen for 1-2min,  then shutdown and reboot automatically,   However, there about 3-4 instances, when I can see the orange logo, ONLY BY slightly lifting the spiderchip off the board (then re-seat?).  But that is not always working.    Out of this 3-4 instances of seeing orange logo,  only one instance could move to a new blue screen saying the xbox hdd need to be formatted,  do you want to proceed?     Surprisingly, it is not HeXEn DVD main menu, which I am expecting.

I understand the spiderchip is solderless, which is not stable in terms of contact with LPC,   But I am quite sure that,  as long as using my finger to press the chip into the LPC, the spiderchip is working perfectly,    But why is so for xbox v1.5 ,   do I need to shortcircuit or ground some points

One thing to note is that a 1.5 Xbox (if it would exist) would require an LPC rebuild to get the required 3.3v and gnd. So basically two additional wires vs 1.4

I also read something about this.   However, According to spiderchip manual, only D0 wire is needed for Xbox 1.0 - 1.5,  other spring-wire can be cut off.     And this Spiderchip had been used for this Xbox (1.5)  10 years ago for softmod purpose, so it should work for this xbox. ;).  

Here is link to the online Spiderchip manual

I was kindly trying to hint that the Xbox you have is 1.4 and not 1.5.

Thanks for reminding me, Lapa988

I looked at its series number, the last 5 digits is 31605, and manufacture date is 2003-04-16.  So according to 

Serial Number Revision
LNNNNNN 20WFF 1.0
LNNNNNN 21WFF 1.0
LNNNNNN 23WFF 1.0 or 1.1
LNNNNNN 24WFF 1.1
LNNNNNN 25WFF 1.1
LNNNNNN 30WFF 1.2
LNNNNNN 31WFF 1.3
LNNNNNN 32WFF 1.3
LNNNNNN 33WFF 1.4 or 1.5
LNNNNNN 42WFF 1.6
LNNNNNN 43WFF 1.6b

 

It is highly likely  v 1.3

The reason I call it v1.5,  because I had an impression (of 14 years) that I ever got the version number from XBMC after I managed to softmod my cousin's xbox. 

:22_stuck_out_tongue_winking_eye:

I will try to play around the modchip again see whether can be re-flash.   Meanwhile I also ordered Arduino Uno R3 kit (expensive than a 2nd-hand xbox ^_^), see whether I can retrieve the eeprom or reflash the modchip as well. 

May the force be with me !  :1311_thumbsup_tone2:

Does the TSOP_M7 BIOS boot to a dashboard?

Which one?

Can you upload and run evoxdash from the booting dashboard?

If it runs, evoxdash should be able to re-flash the modchip.

 

NO,  the TSOP_M7 BIOS didn't boot to dashboard,  and I think it is expected to boot DVDROM (e.g. HeXEN DVD) for modchip recovery according to its "official" instruction:    https://assemblergames.com/threads/1-0-1-5-tsop-recover-bios-tsop_m7-bin.54493/

** BTW,  the 8GB WD HDD should be spoiled (very slow in response),  that is why got ERROR 07

In short,  for TSOP recovery by TSOP_M7 BIOS in modchip,  it requires A15 / D0 grounded,  then off-ground during booting, so Installation-DVD can re-flash TSOP

My intention /hypothesis is opposite,  Keep A15/ D0 grounded,  wish xbox boots to installation-DVD, and re-flash the modchip.     

PS:   1.  For modchip booting in this case,     is A15 grounding necessary?       2. If yes, I need to change my A15 point, which was wrong early,  (I noticed this mistake during another post by AlaskaCC)
