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....

Here is the serialnumber: 28H3RF2H3000M3

Samsung Galaxy Tabpro S BIOS and Micom Version doesn't match
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 [url]https://github.com/tavinus/SamsungBIOSTools[/url] i could extract the newest... -

I flashed a clean bios from the newest HP bios firmware. Now the laptop starts without password, but it lost serial number, windows key etc. and says, that " Manufacture Programming Mode is in Unlock Mode ". What is the best way, to enter all data from my dump with password into the clean bios file?...Leave a comment:

The difference between my model and the df-0013dx is, that i have a CFeon chip instead of the BIOS chip winbond 25Q128JVSQ.Re: HP Spectre x360 15-df1004ng BIOS.../33903/3[/url]Leave a comment:

Re: HP Spectre x360 15-df1004ng BIOS startup password
If i enter 3 times an invalid password it ask for a hp sparekey, which i dont have.
I found another chip, Winbond 25Q80DVSIG. There is also a WSON 8 Chip Winbond 25X20CLIG. But i dont have a probe for WSON 8, so i have to solder. So i first wanted to try the 25Q80DVSIG Chip....Leave a comment:
