want to unroot my tab s3 sm-t813 but having few problems

hello everyone,
i bought tab s2 sm-t813 but its already rooted. i want to unroot it. problem is i am not able to find the same firmware. i find out that region is Germany DBT through smart switch but PDA and CSC are different from firmware available for download.
My PDA is T813XXE0APC8 i searched everywhere but unable to find the same, which stock firmware i can use instead of above mention PDA. i have downloaded the firmware according to region which is DBT-T813XXU1APG2
can i use this one.
Secondly when i check through Droid Info it shows me some weird build number. Below is what its exactly shows

Model = SM-T813 (gts210vewifixx)
Baseband = Not available
Build number = gts210vewifixx-eng 6.0.1 MMB29M T813XXE0APC8 test-keys

i don't understand which firmware is installed in this tab. can anyone tell me?

Thanks in advance....

SM-T813 random shutdowns?

Bought my Tab S2 T813 brand new last week. It seems to crash and reboot every few hours. It does not matter if I am doing anything on it or if it is just laying idle. I'm on June security patch. Known software issue or hardware defect? Already tried a factory reset, did not work.

Thanks in advance.
