S4 mini I9195 revertback to stock problem.

hi, i just sold this phone and they want it back to stock. It had cyanogenmod on it, but i cant remember which one probably cm11. so i went to odin 3.09 and get a UK (BTU) rom from samsung-updates.com. the phone was stuck at the boot logo. okay. so i had another rom and i was try to use odin3.10.6 with no luck. at this point i tried to Re-Partition the phone because i thought CM using a diferent file system. it is now stuck at the samsung galaxy logo. and odin3 gives an error if i try to flash these 2 roms again. (i downloading other ones but it is free slow speed and 1 at a time)
I get 'Secure Check Fail: aboot' so i think the baseband version is not good. if i get a non uk version is it still be the same and english language? or will it have another network's boot logo or anything?
i still can get to the download mode, i just need to know as long as that works this can be saved. if not then i wont waste my time.

i managed to install latest twrp and then flash lineage os. i had some error messages, but the rom boots up and seems like it is working fine. how can i find out which stock rom i need to get it boot up after odin3 flashed?

so after that i flashed a stock rom with odin, but then i had no wifi. i need a good stock rom for Uk model.

edit: okay i flashed another one and now it is all up and running, probably the modem version wasn't match. so thanks for the help! (for myself )
Maybe it will help for someone in the future, i hope. greetings from the past!
