[Q] Boot loop when charging help!!
I have in my possession 2 galaxy s2 i777s one of which was thought to have a charging problem which is why we got the new one. Once i got the new s2 i tried to put the new battery in the old phone and it not only powered up but it also charged. i then put the old battery in the new phone and it wouldn't charge just like before, i keep getting a boot loop where the battery symbol would flash then go away periodically about 15 seconds apart i would guesstimate, this happens for both phones with the old battery, but both phone charge the new battery. I came to the conclusion that the battery may be the problem and set out and bought a new battery and gave the old phone to my mother thinking problem solved, only to discover the problem still existed, replacement battery wont charge same boot loop. Thinking lightening did strike twice and the battery was faulty i returned it and got another one same problem, boot loop when charging or connecting the usb to the PC. I tried the battery in my new phone same problem, i looked at the specifications on the battery to see if they were the same and yes they were exactly the same:
made in china
i have MULTIPLE usb cable that are compatible and MULTIPLE chargers that are compatible and i have tried them ALL. a person suggested i take the battery out plug in the phone then place the battery in while plugged in, didnt work. i tried cleaning the contacts on the battery and the phone itself and nothing, the new phone is rooted but the old one however was bricked in an attempt to root then factory reset, i dont know if this plays a part in it, but remember the battery from the new phone charges in both phones and the the replacements dont charge in any. i had tested the old battery in the new phone before it was rooted or had any apps or anything on it and it did the same thing, boot loop.
im new to the whole do it yourself root and rom thing so please keep that in mind when tossing certain phrases around.
ok after searching some more i eventually found out the reason for this was because the battery I bought was incompatible, though the guys at the store said the battery would work for the i777 which it did, it turns out there is something different about the standard of which the battery was built.
