Dead M93p after Embedded Controller flashing

2019-03-15, 21:40 PM

Hello,

 

I've just flashed my M39p under windows with the following command: SPIW0323.exe FBCT32A.bin /V 32A

I did't flash it with the standard method because I always get the "cannot load the driver error". 

I tried to flash with the ISO method it said the bios is older than 79 version please use the windows flash version. The same thing happened whern I used the USB stick method.

Back to the flashing fault. The flasher erased twice and wrote someting to the flash then the windows frozen. After 10 minutes I switched off the machine. Now it's dead (no beep only the fan spinning). Can I reflash the bin file somehow?

 

Thanks,

I had the same problem on my M93P SFF system. The reason of this is because of incorrect image was flashed into MX25L8006E chip.

I also have M93P Tiny's (USFF), it works on FBCT32A EC bios. Updated it from FBCT29A using SPIW0323 utility without any problems at all, running WinPE 10.

 

USFF system mainboard is IS8XT v1.1 with W25Q80BV embedded controller EEPROM chip, while SFF systems have IS8XM REV: 1.0 mainboard with the mentioned above MX25L8006E EEPROM chip. I guess, it should just stay on the FBCT13A firmware. I also tried to flash FBCT29A with same dead sympthoms on SFF.

You can download original FBCT13A image for M93P from HERE , but there is no any "emergency recovery" method on how to flash this file to the dead ITE controller EEPROM, ITE simply cannot start the correct booting cycle to perform any recovery procedure. You need to buy a cheapest $4 programmer that supports this EEPROM chip (like CH341A) and unsolder it from mainboard to flash the correct image (you can't use IC clip over MX25L8006E to not to unsolder it, just believe me, i've tried).

That's the only way to repair your PC.
