Re: Hp CSL50/CSL53 LA-E791P

Hello,
I soldered the chip and made a copy of the data. I don't know what's in there, because it's after the upgrade attempt after which the computer didn't boot anymore.

Below is your new virgin dump (DMI+Windows key transferred):

[Guide] How to extract ready for programming dump from HP update executable file
https://www.badcaps.net/forum/showthread.php?t=121948

When you have found the right bios version and extracted it the next job,before flashing it,is to copy the DMI (serial number,feature byte etc) from your backup to the new bios.

Use a hex editor with these offsets,just copy from the backup,and use the same offsets in the new bios and paste in.If you can`t do that let us know.

Bios version from broken dump is : 8328 I checked yesterday this version with clean me , zero effect. Only polarized screen.
I was reading that it's best to transfer ME Region from old bios to new , but mine is broken.

Read bios again, it missing a lot of parts, including DMI. Do more readings until you get 2 identical files, if you are using CH341A for sure you have poor contacts.
