A few months back I succesfully rooted my a32 4g with no problems, however recently I have decided to go back to stock firmware. After several failed attempts to do so I finally managed to do it, but I only made a backup using the smart switch app for PC. Now my phone is acting very weirdly and I haven't found a way to fix it. It doesn't detect my sim card (which I think is because of the lack of the efs folder). It keeps closing all my apps, Restarts my phone all the time, and also gets stuck in boot loops which can only be fixed with a factory reset. Please help.
