How To Fix 1601, 1602, or 21 Error Codes During iPhone 3.1.2 or 3.1.3 Custom...


97c343d.jpg
Are you trying to downgrade or restore your iPhone or iTouch from the official 3.1, 3.1.2 or 3.1.3 Firmware to a Custom Firmware and your iTunes displaying the following 1601, 1602, 16xx or 21 error codes? iH8sn0w has just released a utility named iREB (iTunes Restore Error Bypasser), which provides a workaround to fix these errors.
iREB is available for both Windows and MAC Operating systems. Tool runs on both iPhone & iPhone 3G with Firmware 3.1, 3.1.2, 3.1.3, and also on iPod touch 1G and 2G.
So here is the work around for 1601, 1602, 1604, 16xx or 1621 Error Codes…
New version of iREB is out for 3.1.2 Devices… If you’re upgraded to the latest firmware (3.1.2 or 3.1.3) you should use this download / tool for the errors you’re experiencing. New version has additional devices and more options available.
1. Download iH8sn0w’s iREB 3.1.2 archive for Windows or Mac.
2. Start iTunes and put your iPhone in Recovery Mode; to do so, hold Home and Power button in your iPhone simultaneously and release Power button after a while (10 seconds approx). Keep on holding Home button, till you see following error message appearing in iTunes stating.

3. Now close iTunes and start iREB, following interface will open.d00f484.png

4. Now select your plugged in device in iREB 3.1.2 and it will then show the White creen after few seconds. This happens fast so if you didn’t see it don’t worry… You will also hear sounds (maybe) like your iPhone is being plugged in and unplugged from your computer… That’s normal… The ih8sn0w.exe will crash… That’s normal, as long as you get a white screen…
5. NOTE: If you still don’t see the WHITE screen, you should do this… While the device is still plugged in and iREB running, put your device into the DFU mode. PRESS and HOLD both buttons on your iPhone for 12 Seconds and then release the POWER button (Located at the top of your Device) while still holding down the HOME button… Hold down the HOME button for 30 Seconds… (Yes 30 Seconds) until you get the WHITE Screen, the iTunes will come up with a message stating it found an iPhone in Recover Mode… At this point you can let go of the HOME button… you will be asked to restore this iPhone… and the iREB tool will crash
6. Now start iTunes again and select your device (iPhone/iPod) from iTunes DEVICES tab.
7. To restore original settings on your Apple device, press and hold left “OPTION” button on the keyboard (“SHIFT” button for Windows), iTunes will give you option for Upgrade and Restore, click on “Restore” option in the iTunes and then release the “OPTION/SHIFT” button. Select .ipsw file and restore it

Put it in duf mode qnd restore it


If you are getting error (1) or error (6) while downgrading the firmware, you need to put your iPhone in DFU mode before you can restore or downgrade the firmware.
Step 1. Turn off your iPhone.
Step 2. Hold down the power and home button.
Step 3. When you see the Apple logo, release the power button but continue holding the home button down.
Step 4. Open iTunes and wait for it to tell you that its in restore mode.
Alternative Method:

Step 1. Connect iphone to USB then listen to the sound when it connect and disconnect.
Step 2. Hold the home and power buttons until hear the disconnect sound then release power button.
Step 3. Wait until you hear another sound then release home button.
Alternate Method: Going Into DFU Mode Without Button Pushing: (on windows) Easier than timing the buttons just right!

1.) First download the required archive http://www.sendspace.com/file/93fx93
2.) Extract the archive to the root of your hard drive, should be C:/DFU/
3.) Connect your iPhone and ignore iTunes
4.) Goto Start - run
5.) Next type in "c:/dfu/dfu iBSS.m68ap.RELEASE.dfu"
6.) Wait for iPhone to show a "white" screen
7.) Now you may proceed to downgrade!
**also these files are found in ibrickr's directory except for the .dfu file**

I have iphone 3gs , booltloader 06.04, baseband .05.14.02, OS 4.01... i accidentally upgrade its version to 4.1 after that i did downgarde to 4.01 using tinyumbrella n hactivate, jailbresk it using...


You can certainly jailbreak, but you cannot unlock as of yet. It doesn;t matter if you downgrade the 4.1 firmware, that may help you jailbreak but it is the Modem Firmware or Baseband that matters. Your baseband upgrade camme with the 4.1 update. Since you are at 05.14.02, you cannot unlock as of now, period. You cannot downgrade the baseband on a 3GS, so jailbreak using Limera1n or Greenp0ison, but you need to wait for a new version of Ultrasn0w in order to unlock for anything other than AT&T.

Dont worry though, my sources tell me that the unlock is on it's way to be released.

Good luck, contact me anytime.

Unlock iPhone 3G Baseband 2.30.03


Jailbreaking is possible. But not software unlocking. For that you must buy something like a Turbo Sim. For jailbreaking try the program called Quickpwn

Help error 20


i had the same problem what i did was installed firmware 2.0 on my iphone but i could not unlock it what i did then was uninstalled itunes 7.7 and installed itunes 7.5. Then i put my iphone into Recovery mode , which can be done by pressing both the home button and the power button down until the iphone turns off and then once it had turned off i released my finger from the power button still holding down the home screen button. Then once itunes had recognised it was in recovery mode i held down shift and clicked on restore at the same time. for this u need have the iphone firmware 1.1.4 download u can find this by going to http://www.iphoneatlas.com/2008/02/26/iphone-software-114-released/
and clicking on 165 MB standalone download. Once u have downloaded this select it in the menu that will appear by doing by selecting restore whilst pressing shift at the same time. once this process has completed any errors apart from 1600, 1601, 1602 and 1603 are bad and u should redo this process any others can be ignored. Now to unlock,jailbreak and activate your phone u will need to use ZiPhone which can be downloaded from www.ziphone.org. once u have downloaded and installed it make sure your iphone is connected and recognized by itunes click do it all. once this process is completed your iphone is ready for use!
