Hi, I am having a problem with the battery in my Mom’s old iPhone 4.
She recently had to replace her phone because it was showing this screen:
That isn’t her phone, but that is what it was showing. When we unplugged it, the phone completely died so we left it to charge for a while.
It then showed the connect to iTunes screen:
(Also not her phone)
I went to unplug it and plug it into my computer, but it instantly turned off. I plugged it into the computer and when it started, it showed the same screen. iTunes found it and said that I needed to update or restore the phone. I tried, but I got error 21 (some online researched said that this meant the OS couldn’t boot because it had a bad battery). I ordered a new battery online and attempted to replace the battery myself. I had no problem and when I was done and plugged it in to the computer, it showed the same screen. I should also mention that there was never (from the start!) a screen that indicated that the battery was dead.
At this point I was pretty upset because my mom had years and years of photos that were never backed up.
Any help would be very much appreciated.
