I run a business that from time to time gets in large lots of cell phones. Most of the time they're working fine, but the other day I received some in and in the stack I received three i777's. All three of the phones have the same problem, they don't power on. When you power these phones up you get NOTHING. However, if I plug them in the wall, ever 3-5 seconds I get a flash of the battery screen charging but it instantly goes away (not charging). After googling and reading it seems like these could be bricked. They're flawless, no liquid damage, and I swapped the batteries around.
Would a bricked i777 possibly show characteristics of what I had mentioned above, and if so, how do I flash it to the stock rom? I tried searching that and perhaps I didn't search the right variables.
Ordered three non oem batteries. Shockingly all three batteries were bad. I was very surprised at that.
