So, on that fateful day I decided to turn off my iPhone 4 to just reset my phone cos my apps are laggy, and it can't be turned on again. The screen just showed that Apple logo, blinked off, then the Apple logo came back on again. I read the manual and it said I needed to restore to factory settings and I followed the steps and I got the screen to show the cable to iTunes (restore mode). And now the restoring stucks at 60% and gave the error 1.
The history: This phone has been jailbroken before when it's on iOs 5.1.1. After that, I did a restore to factory settings plus update to iOs 7.1.2. Does this erase the jailbreak? So, what should I do now to get my phone back on? I don't mind erasing everything cos I got the backup.
Thanks in advance.
