Thread: iPhone 3g Error 21
10-13-2012, 03:22 PM #1iPhone 3g Error 21
First I Apologize if this is in the wrong section, I haven't been on modmyi for some time.
Problem: The problem is that my friend's iPhone 3G Has Broken Down. I Notice that it is in the recovery loop so i fix that with tiny umbrella and redsnow. However, I believe it did not work because of Error 21. I have tried a few methods to restore the device. First was DFU (Normal) Restore and DFU (Powned) Restore. Both fail me with error 21.

No, It is nothing like that. Can you please just give me instructions? I haven't done anything with it except that installing a jailbreak program that probably was not meant for my device and so boom.

If you are just trying to restore to a regular 4.2.1 firmware then putting it in DFU and restoring in itunes should work fine. No reason I can see why you are getting error 21, that is usually a error associated with custom firmware. Maybe try restoring it on a different computer.

I have tried that but as it turns out my phone was unlocked. I had unlocked my device once again after i restored my device last month. I apologize for that. May i please get the directions on restoring my device from an unlocked 3G? I do not know its previous IOS firmware. I only know that it is unlocked, a 3G, and that i am restoring it to 4.2.1 Please Reply ASAP I need This phone repaired by tomorrow
