ASUS TP202NA Bricked after BIOS Update

[demisoc]

I've read the tutorial here on using the HEX editor to find the region where the DMI data starts, but I couldn't find the serial number anywhere in the BIOS dump. I also tried opening the dump file with FD44Editor, and I got an error message stating "Error parsing BIOS data. FD44 module not found." I'm wondering if I did something wrong or if this file just isn't supported by any of these methods. I was able to get the laptop working with a modified BIOS file from the ASUS website, but I'm unable to do anything with the corrupt dump file.

Model number: TP202NA-OS21T
Serial number: K6N0GR07X2725B
Board number: TP202NAS

I followed the tutorial below, but I'm stuck because I can't find the serial number anywhere in the file. I only see where the BIOS version is listed. According to the tutorial, the serial number should be close by. Is the serial number in the dump file encrypted or did I just get a bad readout?

It's working, but it doesn't have the original serial number. The serial number shows up as SSN1234567890123456

Also, I wasn't able to disable secure boot in BIOS

Hello, I have desoldering my bios chip and try to read and write in it, there is nothing in it, it's not detected and when I put the info of my bios chip in search in Neoprogrammer, it read nothing, do you have a solution ?

Thanks.
