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. :(
Hi Cruzze I think error -1 is motherboard damage so this phone now is unusable. If you find answer on this problem please let me know because I have one iPhone with error -1. From my researches is it hardware issue and so far I haven’t be able to find what exactly cause the problem. Have a good day
