iPhone 7 Bootloop - GSM-Forum

mawaqas · 02-13-2018, 07:58

Hi i have had an iphone 7 come in for screen and housing replacement. After we finished putting it in new housing and LCD, the phone does not boot to iOS and instead keeps rebooting with apple logo. I have tried to boot the phone without the front camera flex with just battery and charging flex and screen connected and its still doing the same thing. I did even try to update it through itunes and it did that without any problem and had no iTunes error code.

Any help will be appreciated.
