How to Bypass Errors Such As 14, 3194 While Restoring iOS 4.2.1 on iPhone 3GS, 3G and iPod Touch

Today it’s fourth iPhone which I updated to iOS 4.2.1, jailbreaked and unlocked with Ultrasn0w. Please don’t assume that I do all this jailbreaking and unlocking stuff for business. In fact, thinking me an iPhone Guru, every day one or two friends of mine came here at my place to get their iPhones unlocked on iOS 4.2.1.

Initially I experienced many problems, but the one which was very irritating to me was:

  • iTunes unbearable errors like 14, 3194, 1600 etc

After using different types of tips, tricks and softwares I have got sort of mastery to bypass and resolve these error and I thought that I should share my experience with the readers of this blog.

How to Bypass Errors 14, 3194, 1600 etc?

These are very common errors which you may face during RESTORE process. The one and only solution to bypass such errors is, at least which worked for me, to use a pwned DFU mode. There are three softwares available for this purpose:

Being a windows users I don’t know much about PwnageTool and how well it performs to bypass these errors but in the remaining two softwares iREB is my favourite now.

I tried Redsnow many times but it didn’t work for me and whenever I used iREB, I got success. Here is how to use iREB to get the PWNED DFU mode:

  • Download iREB for windows here. Though it supports up to iOS 4.1 but it also works on latest iOS 4.2.1 too, at least for me.
  • Close iTunes.
  • ‘Connect your iPhone with PC after switching it off.
  • Launch iREB.
  • Select your device on the screen of iREB UI and follow the onscreen instructions.
  • If you get DFU mode, the screen of your idevice must be blank (black).
  • Now use iTunes to restore iOS 4.2.1 on your iPhone without any error.

Sometimes your idevice may stick into the recovery mode. Here is the solution to get rid of this problem.

  • Connect your iPhone stuck in Recovery Mode or at Apple Logo with PC.
  • Lauch iREB.
  • Select the device on the screen of iREB. ( Its important before you follow next step.)
  • Now keep pressed both Home and Power buttons to turn the device off.
  • As the device turns off (black screen), release Home button, but never release Power button.
  • As soon as Apple logo re-appears, press the Home button again.
  • The screen will go black again after 5-6 seconds. But don’t release any button (Home + Power) till next 5 seconds.
  • After 5 seconds, release the Power button but keep pressed Home button until iREB recognises the DFU mode.
  • iREB will put the device into limera1ned DFU mode.

If you don’t get the DFU mode, retry again and again. After few attempts you will succeed. Now launch iTunes and restore the stock or custom iOS 4.2.1 on your iPhone 3GS, 3G, iPod Touch, or Apple TV to jailbreak or unlock it.

If you still get any error during the restore process, restart your PC and try different USB port. If you are using the front-side, use the rear one and if on left side, use the one at right side, according to your PC.

-> After using all the tricks mentioned above, I am still getting errors.

-> Use another PC then.

    Hi, I’ve put my 3gs into pwned dfu mode many times without a problem but I can’t get it to restore with new firmware in itunes.
    I’ve tryed different usb ports, two different computers and every time I get the same 3194 error.
    I’ve tryed it with a few different firmware even though I know 4.2.1 is the firmware it should take but still nothing.

    When not in pwned dfu mode or regular dfu mode the phone is bricked.

    Do you have any suggestions, because it’s been three days of trying to fix this now and the urge to smash it is getting pretty strong. :l

    1. The first important thing is that you must have SHSH blobs saved with Cydia for the firmware which you are downgrading to. If you do have, install TinyUmbrella and under advanced tab select all options and try again. If you still get error, uninstall iTunes, re-install latest version and try again.

      And if you don’t have SHSH blobs saved, you can’t downgrade.
