Microsoft Surface Pro 7 NEED BIOS. HELP!

[kjchatman]

the majority of these have a non working pch. just because the screen comes on for a few seconds doesn't mean that the cpu is active. press the power button and check if 3.3v shows up on rsmrst# and sam_pch_pwrbtn for a few seconds then check slp_s4#. the first two signals are sent to the pch then the pch sends out slp_s4#

From experience, always confirm bios is OK via uefi tool after backup, it is very important else you'll end up with bootloop when you reprogram it.
You'll get invalid checksum or any error messages at the bottom of the uefi tool.

Again, using another chip instead of the one that came with the surface pro won't allow it to touch or boot fast.

Any information on that topic? I opened the file in the corresponding flash image tool and so far it looked ok. I just get the stupid boot loop and even without the battery i can´t get rid off it. Thats why i was thinking it´ll be the Bios. If you have different routine or software on hand, i´m happy to learn

Good Evening Guys,

second post in this amazing resource-based forum.

Unfortunately my Surface Pro 7 broke on me with the draided boot-lope problem. I already tried disconnecting the battery, but no chance. I desoldered the Bios successfully and read it with NeoProgrammer. I´d be super happy if anyone could take a look at that file to find out what could be causing the issue.

The machine is a 1866 with 8Gb/128Gb config and serial number 026001512653.

Thanks in advance

I guess at this point is more about what the repair shop can do. Swapping a CPU won't be a cost effective option. Like you said, swapping the motherboard for a fully functional one might be the best bet.

1) idk because my surface Is at a repair shop
2) yes, he changed the chip
3) i think yes

The First problem i think was the bios because when i do hackintosh It Is fxked and i think if i find a new motherboard when all components works and the same for the bios i think tò do a swap but idk

Did you try the bios from minhdigital? That one is working for me. Also:
- What programmer are you using?
- Are you desoldering the bios chip or programming in place?
- Did you first cleared the chip before programming and verified it afterwards?
