I’m looking for an unlocked BIOS for my MSI A15 Thin AI B8VF laptop. Here are my system details:
- Model: MSI a15 Thin ai b8vf*crocode Patch Level: A705206
- BIOS version: E16RKAMS.30D
- BIOS date: 2025-06-27
- CPU:Ryzen 9 8945HS w/ Radeon 780M Graphics
- RAM: 64GB Corsair Vengeance RAM 5600Mhz
- ** GPU: RTX 4060
I’d love to unlock the following features, if possible:
- XMP profile support and full memory timing control
- Advanced CPU options (undervolting, power limits, Speed Shift, Turbo Ratio control)
- Custom fan curve or fan table controls
- Access to hidden boot/UEFI/CSM settings
- NVMe and storage-related configuration options
- iGPU settings, including enable/disable toggle
- Secure Boot, TPM toggle, and related security features
- Any other unlocked menus or advanced tuning tools
- Any hidden Menus or items
- Unlock where it wont let me boot if i modify certain things
- *Also unlock the RAM Cap if possible
The laptop is out of warranty, and I fully understand the risks of flashing a modified BIOS. I’m happy to provide a BIOS dump or more system info if needed.
Thanks so much for your time and assistance!

EDIT Been playing with the tools you guys have post here in the guides and this is far as i got. I modified file where it i Unlocks all hidden menus and options, removes all trap logic that will hard block you from starting your laptop if you modify certain settings that are flagged and you are forced to hard reset your bios doing the recovery sequence keys and all. NVRAM lock disabled, fTPM/TPM state check bypassed, rollback trigger prevention, Flash write protection & BIOS update restrictions removed, SMM write lock logic removed. I just cant get it to flash through MSI USB formatted to fag32 matehood to flash it which is my ultimate goal to be able to do it that way or something close. Here the file Bios File (1st try)
Second try still cant do usb flash through bios regular method

Known Issue
Native USB Recovery Flash Method not working currently
Rejection due to:
- File size mismatch (removed modules)
- Possibly invalid BIOS header
Goal:
Restore USB flash support (E16RKAMS.30D via FAT32 USB) or use alternative flashing methods.
Flashing via AFUEFI (Step-by-Step)
This method uses AMI’s AFUEFI tool under UEFI Shell.
Recommended for advanced users.
What You Need:
AfuEfix64.efi (included)- The modded BIOS file (e.g.,
E16RKAMS_PATCHED.30D)
- A USB stick formatted to FAT32
- Optional:
Shellx64.efi if launching directly from boot
Steps:###
Recovery Flashing is Required
MSI BIOS security blocks direct flashing to bios. Must select the recovery flag. Use the following steps:
Recovery Flash Instructions:
- Write ISO to USB (use Rufus, FAT32, GPT, no UEFI validation)
- Insert USB into USB drive and restart
- Press
DEL key while splash screen pops up to enter bios
- Once you enter the bios go to the
Advanced menu and press Co-Piolit+Fn+Right Shift+Left Alt+F2 to enable the hidden bios menu
- Enable Allow
Bios Downgrade Option
- Then go down to
AMD fTPM configuration and Disable that
- Return to the
Advanced menu and go down to AMD CBS from there go down to NBIO common Options go to PSPP Policy and Disable it
- Now go down to
FCH Common Options from there go down to SPI Configuration Options and disable both HID and HID2
- Return to
AMD CBS menu and go down to SOC Miscellaneous Control now select Customized for Microsoft Security Levels, select disable these following options Secure-core Auto-enablement, Trusted Platform Module, Pluton Security Processor, DRTM Support, SMM Isolation Support.
- Now go down to
Pluton Options and select Disable for both options in that menu
- Now go back one menu to
SOC Misc. Control and go to Firmware Anti-rollback (FAR) and select Disable
- Now go back to the
SOC Misc. Control menu and go to Intrusion Detection menu and set to 0
- Go back one menu to
SOC Misc. Control and go down to ABL Console Out Control and disable it
- Go down to
PSP RSPM Switch and also disable that
- Now go to the right to the
Boot menu and go to Quiet boot and disable it
- Also go down and disable
Fastboot
- Make sure
Boot mode select is set to UEFI
- Now go down to
Boot options and select your USB Drive`you flashed and select it from the menu
- Now go to the right menu to
Security go down to Trusted computing and disable it both times it appears on there
- Now go down to
Secure boot and disable it and set Secure boot mode to Custom
- Now go to the
Save and exit menu and select Save changes and exit
22.Now you should potentially boot into the UEFI Shell
- Flash should auto-initiate via
startup.nsh
- When you enter the UEFI Shell type the command
map -r locate the device ID for your USB
- Once you identified your USB drive type
fsX: (Where X=what ever number your USB drive is
- Now your USB drives file system will be the selected one thats active, so type
AFUEFIx64.efi E16RKAMS.30D /p /b /n /x /RECOVERY
- Now it will go through the native flashing method via Recovery and reboot. Now remove the USB and boot into windows
Tip: Use map -r in shell if paths don’t map to fs0:
Flash successful? You now have an unlocked BIOS!
Use at your own risk — backup original and ensure recovery access.
