My phone won't boot up after updating Cydia
I have updated to OS 3.0 and jailbreak and unlocked it using redsnow almost a week ago. Everything worked fine until I update the Cydia tonight.
After the update it hanged and I had to restarting it by pressing the power and home button. Now it won't boot up. It shows the Apple logo and after that a black screen will appears.
Does anyone encountered this problem?
Is it safe if I put the phone in DFU and restore OS 3.0 again? I mean can I still unlock it after restoring the OS 3.0?
If not can you please tell me how can I solve this problem?
RE: My phone won't boot up after updating Cydia
In my case its 2G iphone, and I recovered it by entering DFU mode and then restoring(using iTunes) to its jailbroken 3.1.3 firmware by snowbreeze. You might want to back-up your data first before restoring. I'm not sure if this is possible in DFU mode, in my case I was just too focus on making my iphone usable again that I forgot to backup first.
To enter DFU mode:
- connect your iphone to your PC
- launch snowbreeze GUI.
- at the bottom there is a DFU button, click it
- follow screen instructions, disregarding the iphone flickering display.
