I’ve rerun through the whole process a couple of times, and my device is STILL bricked. Help?
I seriously love you guys. Seriously.
I know this may not the place post this, but since your backup worked, how do I know you didn’t splice the APK program with something that would trace my typing? Since programs/apps for smartphones are the fastest growing medium for malware and viruses…
How can use semi-noobies protect ourselves? Mobile VPNs or something like that? I’d greatly appreciate a point in the right direction
P.S. I just tried to re-root my phone today and it says that the SU file is read only. Additionally, this is a different firmware that I originally had on my phone running. Similar but not identical. Can you point me in the right direction to find the original firmware with the SU file intact so I can re-root?
