T540p Custom Bios

#1 Post by averagenokiauser » Tue May 06, 2025 11:19 am

Hello, are there any custom bioses available for T540p? With custom i mean with no whitelist or one that has advanced options.

Thanks for sending these. I followed the second guide and everything went well. I also used me_cleaner and that works perfectly too in case anyone wants to disable that on T540p.

I thought that T5xx BIOSes didn't have a whitelist.

Can you detail what me_cleaner settings you used. It will be helpful to future readers. If you are unsure, just leave the me_cleaner switch you used. Thank you.

For me_cleaner the command i ran was

Code: Select all

python me_cleaner.py -S -O modified_image.bin original_dump.bin
This is in the external flashing documentation and i didn't change anything. Keep in mind that the chip that contains ME is the one closer to the SIM card slot and the one further away is the BIOS chip.
