Chosen Solution
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 ?
With the OP description I would start with battery replacement. A lot of reasons to start there. It is one of the few parts in iPhone to wear out. It is most vulnerable part in iPhone. Easy to replace. Among cheapest part in the iPhone. All the features of what is wrong point to battery.
If your phone is Jailbroke I would restore it. Also the wifi and cell antenna connectors can be tricky to get re connected properly, I would recheck them .
brandi what date did it get set to? mine has same issues and i tried restore in dfu and pwn dfu all i get is errors…..mine was dec 31 1969… i tried replacing my battery and still same story
Was this issue ever resolved? I am having the same issue. Thanks for any help?
I’m having exact same issue as the original poster and question … to the letter .. I could have written the question / systems message myself and it would have said the same thing. Therefore, there’s a clear common issue here that’s popping up for me and others. I have replaced the battery to no avail. Any solutions yet?
I have the same problem, the date is set on december 31 1969 and dosent recieve wifi. Some say you need to connect to computer and do a factory reset, which will reset iphone to a brand new phone but will lose everything unless backing up your files. Search on youtube how to do a factory reset with itunes, and try it. It will delete everything, but will resolve the probblem, in order to save your things back them up… HOPE THIS HELPS :)
i had the same exact problem. exactly. cleaned dock and plugged to comp. didn’t do any restore or updates and it is working. try cleaning dock and plug in. somehow it fixed mine. UPDATE: This worked for about a day… now back to the same problems. UPDATE: It was just the battery. Took it to SoCal iPhone Repair, they replaced the battery and its been working fine for over a week now.
