[REQUEST] Thunderobot 911 V350SNX-HL Insyde BIOS - Remove CpuSetup write protection
#1
Laptop: Thunderobot 911 (V350SNX-HL)
Board: Clevo V350SNX-HL 
BIOS: Insyde H2O 1.07.P16RQLM1 (01/11/2024)
CPU: Intel Core i7-13650HX
OS: Linux

GOALS:
1. Remove write protection on CpuSetup EFI variable
  (GUID: B08F97FF-E6E8-4193-A997-5E9E9B0ADB32)
  to allow disabling CFG Lock at offset 0x43 for CPU undervolting.
2. Unlock advanced BIOS menu options if applicable
  (power limits, XMP, voltage settings, fan control, etc.)

CONFIRMED:
- CpuSetup is write-protected at firmware level
- setup_var.efi returns WRITE_PROTECTED from UEFI shell
- modGRUBShell setup_var_cv returns error 0x8000000000000008
- MSR 0x3A = 5 (CFG lock enabled), MSR writes blocked
- Fpt.efi dump and flash tools available and working
- Intel Boot Guard may be active (13th gen Clevo platform)

CONFIRMED LOCKS (from IFR extraction of actual BIOS dump):
- CFG Lock:            CpuSetup offset 0x43  = 0x01 (need 0x00)
- Overclocking Lock:  CpuSetup offset 0x10E = 0x01 (need 0x00) 
- UnderVolt Protection:CpuSetup offset 0x381 = 0x01 (need 0x00)
- BIOS Lock:          PchSetup  offset 0x1C = 0x01 (need 0x00)

All blocked by CpuSetup write protection at firmware level.
Full 32MB BIOS dump attached (obtained via Fpt.efi from UEFI shell).
Flash tool available: Fpt.efi + FlashMe.nsh from Clevo package.

BIOS dump download: https://drive.google.com/file/d/1Y_jlPgk...sp=sharing

Thank you
