No Network, Won't Stay On If Not Plugged Up to The Wall.
So i Changed my LCD following an ifixit guide and the results were perfect upon completion, i finished with no errors....
about 2-3 weeks later, i had my phone on the charger, went to sleep, and when i woke up my phone was off.
i turned it on and it worked perfectly, as soon as i unplugged it from the charger it turned off and would not power on until i plugged it back up.
when plugged into the computer, it goes into a reboot loop.
and now all of a sudden, when powered on while on the charger it does not get wifi, nor a cellular signal.
i took the phone apart. cleaned the dock connectors, and all the things suggested in the already answered questions but nothing has worked for this problem that just came out of the blue.
even now when i turn the phone on , it doesnt even know the correct date and time.
any suggestions ?
Is this a good question?
