iPhone 4 error 21 and will not start
Hello, i have a big head cracker, LOL
So I buy this iphone 4 as faulty, cheap... I knew the phone was stuck in in restore mode and I was thinking that all it needed was to plug and restore, nothing is easy in live, and this is no different.
So if I plug the phone to the wall or PC I get the apple logo on the screen, if the phone is not connected to wall or PC, the phone will not turn on nothing happens not even if I press the power and home button.
I now the battery is fully charged so it should power on, but it does not, only if connected to wall or PC. Is this normal? the phone doing this with error 21 the battery connector looks in good shape, and i tried the battery on other iphone and it works.
So when I connect to PC and try to restore I will get the error 21, so I Google a fix and do as instructed. I deleted a ETC file and a different error appear, all I needed to do was update itunes, so I try again to restore but error 21 comes up again With or without ETC file (file is in recycle bin).
I think the phone must have been jailbreak... But if anyone have any ideas please help... I afraid the logicboard might be busted, but the PC recognizes the phone and installs the divers needed... I just to novice at iphones :) i gess...
Thanks guys and sorry for the big love letter, LOL
I read in some forum about custom ipsw and TinyUmbrella but i have no idea how this will help, i tried redsn0w but it did not work i just tried the jailbreak option.
