I have an HP Elitedesk 800 G2 35W with the following error on boot:
(A7) Me FW Downgrade - Request MeSpiLock Failed
After 10 seconds, it boots past this error, but I would like to fix this.
I found this thread on the forum with the exact same problem:
But it never realy got fixed AFAIK.
I can’t find any hidden BIOS menu to unlock ME flashing. There is an FDO jumper available, but as said in the thread above, shorting these 2 FDO pins makes the system power on and power offf after 2 seconds.
I’m about to order a SOIC8 + CH341a set to flash my chip.
Is there any guide available on how to do is?
The MB indeed has an FDO jumper, but when shorting these 2 jumper pins, the MB powers on only for 2 seconds and powers off again. Would be great if HP made it do what it was supposed to do ;-). I’ve ordered a CH341a + SOIC8 to read+flash the chip by hardware. It will arrive in 2 days. I’ll dump the full image, clean it (CSME v11.8 so guide part D4?), flash it back and I’ll report back!
I received my ch341a + soic8 today.
I dumped my W25Q128FV bios.bin 3 times with AsProgrammer v.2.0.3a, verified MD5 and they were all the same!
I then followed the ME cleaning guide and flashed the outimage.bin back to the chip. First time didn’t work (I programmed the image, but not unprotect + erase + program + verify like it should have been done). 2nd time I did the unprotect + erase + program + verify and BAM, my HP Elitedesk’s ME is al good again! Tnx to this great forum with excellent guides!
