hey everyone
i recently corrupted the efs folder on my s3 and gave back to samsung under warranty. they told me that the s3 has a corrupt mother board and that my warranty was only in Tehran (I live in dubai) so i gave the phone back to the store where i bought it
he told me he would repair it he said he would change the motherboard. I got it back today and on opening the app drawer i found superuser with a bunch of adb requests i want to update but i'm scared that he just patched the modem and didn't change the motherboard. If i update will i lose my connectivity again? And how do i tell if the modem is patched? Also is it safe to update?
Thanks in advance
