Apple released iOS 4.2.1 GM for developers and it’s already leaked in the wild. Earlier today we posted a guide to Jailbreak iOS 4.2.1 iPhone 4, 3GS, 3G, iPod touch, iPad With Redsn0w. If you downloaded those Beta builds and now you want to go back to iOS 4.1 or lower for whatever reason, we created a step by step guide to downgrade your iDevice from iOS 4.2.1 beta to iOS 4.1

Note : iOS 4.2.1 is still in Beta and you needn’t to edit your host files to bypass Apple signatures.

Instructions to Downgrade iOS 4.2 Beta

Step 1: Download and place OS 4.1 on your desktop, now put your iPhone/iPod/iPad in DFU mode with following instructions.

  • Connect your iPhone to your computer.
  • Turn iPhone off.
  • Hold power and home together for 10 seconds (exactly).
  • Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
  • A few seconds later iTunes should detect your iPhone.
  • If the Restore Logo is present on the screen, you are in Recovery Mode, not DFU.

Step 2: Once your iPhone is in DFU mode following message will be appeared in iTunes.

restore

Click on “OK” , Now hold Option key (Mac) and Shift Key (Windows) while clicking Restore in iTunes and browse the iOS 4.1 firmware for your iDevice. Now the restore process will take 10 – 15 minutes.

Step 3: After restore process if you encountered an error message like 1011, 1013, 1015, just ignore them(Actually the firmware is already successfully installed). To exit recovery mode download Recboot, once you finishes your download launch Recboot app and hit the “exit recovery mode” button.

RecBoot

  • Recboot for Windows : http://bit.ly/9he64R (Requires .Net 4.0)
  • Recboot for Mac : http://bit.ly/bBelW2

But if you encountered with error message like 1601, 1602, 1600 or anything else then try putting the iDevice into DFU mode and try again.

    Hi… Thanks for the above post… It worked. However, those who have TinyUmbrella v 4.00, can also use it to kick out the recovery mode…
