[dutchgaucho]

Hello there, I'm having a Surface Pro 7 that turns on for 4 seconds an then shuts down. I've tried Peste's BIOS (posted in #8) and it works but touch is not working and DMI data obviously does not match. Could somebody fix mine?
Thanks!

My apologies. Please help me fix this bios for Surface Pro 7 (ME error, can't boot from any drive / usb stick, sometimes doesn't boot at all). I can get into UEFI without problems, but it still does not want to boot past that no matter the settings.

Model: 1866 (i5/8/128)

Board revision: 2.0B

Thank you.

Hello,
can somebody please help me with my Surface Pro 7 BIOS? It's having ME problems (bios showing ME version 0.0.0.0) + it is unable to boot from SSD or flashdrive (and sometimes it doesn't boot at all). Thank you SO much!

PS: It is interesting that the working Rev 1 board BIOS that I have from a previous post is not working on the Rev 2 board.

Thanks for sharing !!

Nice one !

The issue is resolved!
The error was always in the hardware and not in the bios!

I understood that if I turn off GPP_D_14, then the tablet works, but if I turn it ON, then i get boot loop. I started looking for where this contact goes according to the schema motherboard_surface_pro7_1866.zip

the tablet had to be a boot loop because the capacitor always shorted +5 volts to ground.
GPP_D_14 -> RTD3_TPANEL_PWR -> U6407 -> +5V -> R6417 -> C3002 !!! has a short circuit !!!
I replaced the C3002 with a good one and everything worked.

Thanks for sharing !!

The tablet does not load, only shows the logo for a few seconds. I cleaned the ME region (with Intel (R) Flash Image Tool. Version: 13.0.37.1556) and got no noticeable result. Then I cleaned ME region and disabled only one option
ME Feature Pins: TouchResetGpio value="GPP_D_14" -> TouchResetGpio value="None" (Configure Intel(R) Precise Touch Technology Reset GPIO)

The touchscreen does not work after cleaning the ME region

What I did:
The tablet does not load, only shows the logo for a few seconds. I cleaned the ME region (with Intel (R) Flash Image Tool. Version: 13.0.37.1556) and got no noticeable result. Then I cleaned ME region and disabled only one option
ME Feature Pins: TouchResetGpio value="GPP_D_14" -> TouchResetGpio value="None" (Configure Intel(R) Precise Touch Technology Reset GPIO)


The tablet started up, Windows updated the bios, but the touch screen does not work either in UEFI or in Windows.

I compared the bios settings (xml via winmerge-2.16.38) with other bios from similar tablets and all the options are identical. Only when i change this option TouchResetGpio value="None" then the tablet turns on.
Who knows what this option means and how I can repair the touch screen?



I read this but it doesn't help:
MS Surface no touchscreen after cleaning ME Firmware **FIX**

Hello

Surface boot loop after update. All tricks on internet won't work so I've read BIOS Winbond chip. I hope this is the reason.

Thanks
Claude

try it.
my tablet started booting with these settings but the touch screen is not working

[samstown]

it's too early to give up! I am currently studying this topic. if I use different Flash Image Tools, I get different results for some reason. But at the moment the touchscreen does not work and ME firmware is shown as 0.0.0.0
If I can repair my second tablet (because the first one was successfully repaired), I will try to deal with your case again.
What programmer are you using? Because my CH341 programmer reads this bios for about 3 minutes and writes for about 23 minutes.

Hello,
I have CH341, that was my first one. Then I had RevealProg, it's very good but fragile.... and now RT809F, this one is really really good and stil cheap.
I am happy to try again if you think there is a way.
Thanks

I've tried again. I've flash orginal ROM and the two modified ROM I got on this forum.

If anyone has an idea otherwise it will be time to give up.

For interest, provide two bios images 1) the one you last recorded on the tablet with the ME region cleaned 2) the one that is already on the tablet. I wonder if it is possible to find what changed between them to understand if there is a clue where to look for the cause of the breakdown.

Please help to edit the bios, or tell me where to go next.

problem at the moment:
- the tablet takes a very long time to load (about 1.5 minutes to get into the bios interface)
- the touchscreen does not work
- there is no "Intel Management Engine" firmware


A short story:
After the update, the tablet has a boot loop every 3 seconds. Only the logo is visible for 3 seconds. I can't enter UEFI, I can't boot from USB.
I read bios backup 1_AsProgrammer_read_original_boot_loop.rar
I opened this backup in the program "Intel (R) Flash Image Tool. Version: 13.0.20.1312"
replaced that file "ME Sub Partition.bin" with this "13.0.55.1889_CON_LP_D_PRD_EXTR.bin"
and made a build 8_outimage.rar


Now the tablet takes a long time to load, in about 3 minutes I can see the Windows recovery page and I can see the files on the SSD to choose where to recover Windows from. From this we can conclude that the SSD is working

it looks like the tablet is physically working, and there is no damage to the hardware.

Please tell me what to do next?
