Ask Winmate M133WK - Xentry Diagnosis Pad 2 BIOS Locked

Hi everybody,

I looking for password of my tablet Mercedes Benz, because I can't install the update of the update.

I have EC_133WK.bin and BIOS_M133KW_Corporate.bin files.

I did update the bios via windows with the EC_133WK.bin file but still same, the password is there. (U92 GD 25Q20CT)

I unsoldered the chip U89 (U89 WINBOND 25Q256JVEQ), erase and write file BIOS_M133KW_Corporate.bin with CH341A. But still same.

I already dumped all chip around.

There is a 25L8006E chip (U65 25L8006GE M2I-12G 5E395700) I have just dumped. Someone told me password should there.

I let you pictures of my motherboard. And link to the files I got and dumped.

is there a way to find password from these files (I guess into the 1 mb file) ?

Thanking in advance.

Best regards.
