Samsung Galaxy Tabpro S BIOS and Micom Version doesn't match

[TJ65]

Hello everyone,
i made out of two broken Samsung Galaxy Tabpro S one that works partially.
The one Mainboard had a broken screen output but working hdmi (usb c adapter) output and the other didnt start at all.
I switch the bios chips and now the tablet starts but very very slow and it takes some trys to get it starting.
The problem is, that the micom Version doesn't match with the bios version, see picture.
How can i update the Micom Version? The Samsung bios update wont work.
With https://github.com/tavinus/SamsungBIOSTools i could extract the newest bios update (P14HAB)

BIOS Version: P14HAB
Micom Version: P13AFH

It took me some time to get the serialnumber from the donor bios. I couldn't boot windows and it doesn't want to boot from USB. I took the SSD from my third Tabpro S and got i booting.
Here is the serialnumber: 28H3RF2H3000M3
There was a sticker on the backside with has the letter P on the end of the serialnumber: 28H3RF2H3000M3P

Can i merge my BIOS Dump with the ME Region from the Virgin Bios? Or does it not update the ME Region?

Very sad, that no one answered. I found the solution. I made BIOS dump from a working Tabpro S, analysed the ME Region, found the right ME Region 11.0.12.1008_CON_LP_C_YPDM_PRD_RGN.bin and rebuild the broken BIOS dump. After that i made a BIOS update with the Samsung Update Tool and it is working great since then.

It is a very busy forum and sometimes posts go unanswered. You could have bumped the thread and someone would have helped you. Anyway, i`m glad you managed to repair it
