So I replaced the battery, however nothing seems to be working now, the old battery doesn’t do anything either. I can connect to itunes, but the screen and vcibrate aren’t working either
Did you guys disconnect the screen while you replaced the Battery? If you didn’t, you could have pulled on the cables connected to the LB. If you did, try to see if the cables are properly connected to the LB. Worse case scenario you need to replace the screen or get another battery. After a battery replacement I always do a hard reset to the phone. Hold the power button and home button until the phone powers off and on. Then connect it to battery to see if it’s charging. Hope this helps.
i have the same problem replaced the battery today had the phone appart endless times checked everything and still wont turn on ive connected it too my pc done endless attemps through itunes and still no joy
