![]() ParseFile: invalid data checksum E3h, should be 5Ah ParseFile: invalid header checksum 00h, should be B6h ParseFile: invalid data checksum 0Bh, should be 09h UEFITool 0.22.3 give me bunch of errors like these: ![]() After some investigation I dumped bios file using fpt -d -bios backup.rom from Intel TXE System Tools v2 r2. Last known bios version is 1.24 avable here. ![]() So that means that modded BIOSes in newer laptops (I can say for now, only from Acer) can be only flashed via external programmer.įorgot to mention, mclarke2355 has a thread ( Link) where he offers his modded Acer E5-572G BIOS which can be safely flashed to recovery mode, this step does not apply to newer laptops as I said. With that find I decided to use Intel FPT to flash the BIOS region (before I disabled the option BIOS Lock) but new error appeared (28) which says that Protected Range Register are enforced in the BIOS. We also discovered that it is not necessary to remove the battery to initiate BIOS recovery (which actually in newer laptops like mine has hardware checks if you’re trying to flash modded BIOSes) Got an error message after reboot saying that the BIOS image is invalid.Īlso I’ve been working with mclarke2355 who generously modded my BIOS with not just new Microcode but also Intel RST, GOP, VGA BIOS (Intel), Realtek OROM.
