TECH SAVVY PEOPLE I NEED YOUR HELP!
Anyone on here tech savvy with Samsung phones and firmware flashing using Odin etc?
I bought my Galaxy s21ultra refurbished from backmarket.
The build for some reason is SM-G998U1 with CSC XAA-XAA-VZW which is for north America when it should be SM-G998B with CSC BTU or H3G for the UK
It got an OTA update (which shouldn't be possible with it being a north American build) and it updated my phone from OneUI 6.0 to OneUI 6.1 which has caused my TSP (touch screen panel) to become unresponsive.
I have looked through every tutorial I can find to try and fix this including downgrading down to 6.0 using Odin and updating TSP firmware through * #2663 # but neither are possible.
The TSP firmware shows N/A and I can't find where to download the manual TSP FW to install from internal storage.
If anyone can help or knows any possible way to get this working I'd appreciate it so much. The phone is in pristine condition with a beautiful display but just can't get the touch screen panel working and I can't afford to replace the screen or buy another new phone.
If I can't fix it it's £350 down the drain.
Please share, this is driving me insane.
Thank you
