Error 50 or -1 when I tryed to recover the phone
Hello, I bought a used iPhone 5S on eBay in a good condition. I received the phone and tryed to activate it over iTunes and internet but it doesn't worked. The activation failed because of the not reached activate server).
So I decided to recover the phone. All seems good until the process bar reached the end of the Apple logo. The process bar stucked and I got the error 50. After some minutes the iPhone turnes off and since then I only see the iTunes logo if i start the phone.
I reinstalled iTunes and all other 3rd party software, cleaned the registry with CCleaner, used another Lightning cable and turned off my anti virus software but without sucess.
So I installed iTunes on my 2nd PC and tryed it out. On this PC I got error code -1.
Here I setup the DFU mode but its not better.
I read that maybe the baseband chip is faulty but in iTunes I can see the serial number.
Does anyone know what I can do or is the phone broken? I think I can't blame the seller because it worked as i received the phone. :(
Is this a good question?
