Let's try to disable bios rewrite protection using EFI Shell
1. Take USB stick and format to FAT32
2. Create directory structure EFI\Boot
3. Download BOOTX64.EFI http://www.mediafire.com/download/81vegw...+Shell.rar
4. Put downloaded file to Boot directory.
5. Restart and enter BIOS setup.
6. Make sure you have following values:
Legacy Support: Disable
Secure Boot: Disable
7. Reboot and press F9 to boot from USB stick
8. Give commands:
setup_var 0x17F 0x00
setup_var 0x17E 0x00
setup_var 0xC4 0x00
setup_var 0x17D 0x00
9. Reboot and after that run this tool as Admin

Hi,
on number 8 i got first errors. The setup_var tool says that the adresses 0x17e,0x17f,0x17d are out of range. Only the adress 0xc4 change Form 0x01 to 0x00.
After that I can not Boot into OS. I can enter the seup menu or the boot menu. If I try to Boot via priviusely created USB key with Shell then I get the Shellpromt but canot enter a command to set the value back to 0x01...

You can easy recover laptop by clear CMOS.Just dettach it for 10-20 sec and attach again.
So i have no idea how bypass 280 protection.So upload bios dump by programmer and i'll modify it.

hi,
recover successful done with "load default settings" in setup menu. I can dump the flash later when i at home. Do you need the entire flash 12MB? or only the relevant 4MB?

Hi!
I need both dumps!

Hello Da Vinci Code!

i have successfully removed the white list from the current 2.64 BIOS. I use the pached module by BD in my dump and flash the new pached dump via programmer to flash.  

After spending some time on google i get: https://www.techinferno.com/index.php?/f...ure-flash/

so i think this could be currently impossible to flash the modified BIOS by stock update application. What do you think?

Any other suggestions to go around these signature thinks?

hello all!
someone have dump of 4mb flash chip for x230t?
