A suggestion! Have at least 3 identical backups of this machine.... -
I was able to make identical backups! I simply removed the 1.8v adapter and made the backup on the CH341, selecting the chip "W25Q512JV", and the RT809f already has the correct chip, which is "W25Q512NW".
The backups were all identical, and I was able to remove the BIOS password. I hope the information will be useful to future colleagues in the area....Leave a comment:

Hello, did you use which tool to read this chip? The RT809F already has this chip on the list, I made 6 files of the file and nehum are the same....

Exactly! I've made 6 backups so far, and none of them are the same, the ones I put here are just 2 of 6. I made backup using CH341 with Neoprogram and 4 others with rt809f, and none of them are the same....Leave a comment:

I got a Latitude 5350 with a locked bios, it uses only 1 bios chip (W25R512NWEQ) 64mb file. I've already made 6 different backups and none of them are the same, making the comparison with HxD. The most bizarre thing is that this model does not contain Intel Engine/Graphics/Independent Firmware. I'll leave some files here so you can analyze them, this model is very strange.

Lenovo Thinkpad E14 Gen 6 AMD Bios Password
Dear friends, a thinkpad E14 Gen 6 amd came to me to do bios, but I don't have the schematic of this equipment.
Would anyone have Vertyanov's scheme to provide? Or can you say which model is compatible with it to read the ITE?

I tested this on a 640 g9 bios version U75 and it didn't work. It makes the corrections and at the end in tiny hexer a last message appears as in the down image. I save the file and then flash it on the machine, but at startup it still asks for the password. I think you need to correct something else within the patch file and the program doesn't do it, according to another comparison of unlocked files that I see.

Yes, I heard that changing the MEC1503 works, can you tell me where you bought it? Has it already come programed?...Leave a comment:

Until then, each one speculates a type of theory, the fact is that it came from the factory and it was programmed. There are people who are managing to unlock these machines with MEC1503, but they keep this secret at 7 keys as I said before.Leave a comment:

You need to remove the chip from the board, this equipment does not support reading with a soldered chip....Leave a comment:

Your explanation is very good, so will changing the mec1503 chip resolve the blockage? I saw some selling on aliE....Leave a comment:

Some people claim to have unlocked it. Until then it's a mystery, because I've heard that some can do it, but they're keeping this "big secret" under 7 keys,They say they are afraid of spreading everywhere.
PS: as if all mec1503 machines only exist for them....Leave a comment:

Thank you for these ways, but unfortunately t14 gen2 only has eSPI in its scheme. The fact is that there are people who do this unlocking but are keeping the seven keys, they don't sell and also don't contribute with the information, I've already taken more than 10 pieces of equipment of this model and dismissed it for not having a solution for them, and giving it as scrap. Right here in the forum there are people who say they managed to solve it but don't pass on the information....Leave a comment:

Were you able to solve it using Segger?...Leave a comment:

I would like to inform you that with a lot of persistence I managed to rebuild the machine's bios and now it is working again....
