iPhone 5 doesnt power on
my iphone 5 was working perfectly well after i did battery replacement, however, two days down the line, i decided to test whether my bro's battery is still working so that i can use it should mine have some problems since he left it at home. i then started off and tried to take mine out. very unfortunately, i happened to apply more force on the battery connect trying to pull it up with my nail so much that i broke this thin cable from the battery. I then made a stupid decision to try solder back that cable together, i scratched it, soldered it and tested any shot with the multimeter, i got none. I then put back the soldered battery(the new one that i just put it)...but the phone couldnt charge, it kept looping showing apple logo for a few secs and off again...i took it out, tested the connection(continuity) and any short,and put it back again, there was no luck! i then bought a new battery, i tested with multimeter to ensure that it had a litle juice, i then put it in, the case was the same, there was looping, and i cant even get to recovery mode!
can anyone help me out as to what can be the possible problem caused by all this mess? could it be that the phone had been shorted by the soldered battery. what can be affected by the wrongly connected or shorted battery in an iphone circuitry?..i am really confused and full of regrets!...help me out please!
Is this a good question?
