which method can be used to truly recover the STR to default factory system?
Hi there,
I have done rooting operation before, and now I decided to back the default system.
google for a while, and try the method" after press power key, when the screen come up, press the bottom two pageturn key, wait for hint, press home button 2 times", it indeed recover some, but I found still it's not the clean system as I received from BN.
Any more deep suggestion?
All the best!
