Lol sorry. Yes, every time. Well, i have tried XFA and XFV, and then it either installs a turkish or german rom.
I am slow downloading a rom that clearly says XFV at the front of the filename, but at the sites allowed 70kb/s.
I booted up with power, home and vol up, phone said Installing package, but then it showed no sign of the words multi-csc anywhere.
have you tried this:
So I finally managed to change my CSC from TPA on my unbranded S8+ (G955F) to IUS, and now I can use S Pay.
This is what I did:
1. Downloaded this Combination File from
https://firmware.gem-flash.com/index.php, I had to pay $3 USD to get access to the download.
COMBINATION_FA70_G955FXXU1AQD1_CL11075178_QB130870 97_REV00_user_mid_noship.tar.md5.rar
2. Downloaded Odin 3.12 (latest), other versions did not work.
3. Downloaded this ROM:
https://www.sammobile.com/firmwares/.../SM-G955F/IUS/
Latest version (January 1st, 2018), it is from ATT, but I dont care care about that haha.
4. Run Odin, download mode on phone and install firmware downloaded from SamMobile.
5. Restart phone, enter OS and do factory data reset.
6. Remove "hidden.img" from HOME CSC (included in firmware) with 7Zip. It has to be repacked to a Tar file.
7. Go back to download mode, open odin and choose the combination file under AP and the recently modified version of Home CSC under CSC.
8. Reboot and enter factory mode.
9. In Factory Imei input *#243203855#
10. Choose IUS as the new CSC.
11. Boot back to download mode.
11. Reinstall firmware, now using normal CSC file (not Home CSC).
12. Boot up to ATT Mexico phone.
