[Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization



Hello, everybody!

I just came across a contradiction:

I opened the dump file for my bios in UEFITool and it shows these messages:



So I opened it in HxD and made the changes:

befor


after



Then, I opened it again in UEFITool and the invalid checksum message is gone!



But as my goal is to ‘clean up’ the ME, I opened it in MEA to confirm that everything is right and I ended up facing this contradiction:



… that is, while UEFITool says "Checksum: 5Dh, invalid, should be 7Ch", MEA says "Wrong $FPT Checksum 0x7C, expected 0x5D! "

Would someone, please, tell me which one I should consider correct? (or wrong)

I will keep waiting.
Thank you very much.

Here is my dump file:
