Accidentally updated your iPhone 4 or 3GS to iOS 6.1.3/iOS 6.1.6 and lost its jailbreak status/stuck on the upgrade process with a “SIM not supported” message in iTunes? It is a usual thing that happens to iPhone customers who buy the handset from second-hand market. Those new users would not be aware of the fact that the phone was previously unlocked on a particular iOS version with software like Ultrasn0w: such devices will loose the activation status as soon as it gets updated to new iOS. So during the upgrade, after the restart, the phone may immediately display a message- “connect it to iTunes to activate the iPhone.” Soon the device will get deactivated, and a “no SIM card installed” or “SIM invalid” message will show up. Now what you can do to get out of this state is jailbreaking the phone again with proper tools.
Those iPhone 4 or 3GS users having iOS 6 up-to 6.1.6 on their device can make use of the new Redsnow 0.9.15b3 to jailbreak it again and then activate it with Ultrasn0w: this process will make the device carrier independent, and it will open up as usual.
“Activation error” – Activation request could not be completed if the problem persists please contact the support.
The following method will fix above given error and will automatically activate your iPhone if done correctly. Please note that if you rely on Ultrasn0w unlock make sure keep your base
Steps to jailbreak an iPhone with Redsnow 0.9.15b3.
Although our aim is to jailbreak iPhone 4/3GS running iOS 6.1.3/6.1.6, we use iOS 6.0 IPSW for this operation. So don’t get confused at any point.
1. Download Windows or Mac version of the Redsnow 0.9.15b3 app from our home page.
3. Connect your iPhone to the Mac or PC, after downloading the necessary software.
4. Remove the SIM card ( only if you need hactivation), and then execute Redsn0w.
5. Click on Extras, and then “Select IPSW” button and locate the downloaded iOS 6.0 file (yes, 6.0) using the finder (Mac) or Explorer (Windows).
6. Once the Redsn0w identifies the OS, hit the Back button and go back to the main window of the application.
7. Now click on Jailbreak. In the next step, choose to install Cydia and proceed. The jailbreak process will begin and at some stages the Redsn0w will request manual interventions: you have to turn off your iPhone and take it to the DFU mode whenever required.
8. Your iPhone 4 or 3GS will boot into fully activated mode once the jailbreak process ends. Yes, hactivated! You do not need UltraSn0w here.
9. The outcome is a tethered jailbreak; so do not worry if you cannot find the Cydia application in the Springboard after step 8, or it is not responding to taps. You will have to run Redsnow 0.9.15b3 app again to boot it tethered and for the jailbreak to work exactly as desired. Those who just wanted to avoid the activation screen/SIM invalid can skip the upcoming steps and start using their iPhone in the unlocked state.
10. In order to boot the device tethered, follow the step number 5, and then click on Just Boot button instead of going back. Now again Redsn0w will take you through the step 7 discussed above- do what it says.The fully working Cydia package will be up ready in your phone as you restart.
Update: With the launch of P0sixspwn 1.0.8 it is now possible to transform the tethered, Redsn0w based jailbreak explained above to untethered by installing P0sixspwn package from Cydia. Just search for “P0sixspwn,” fetch and run it: the device will boot untethered, and you no longer need Redsn0w to start the phone in jailbroken mode.
Common Error fixes:
- Redsn0w says the IPSW file is invalid?
Probably you’ve provided a wrong iOS as input. This method requires the user to download iOS 6.0 file, not iOS 6.1.3.
- My phone is stuck at the Black/Pineapple screen after reboot and its not starting?
Well, then you can use the “Recovery Fix” option in Redsn0w Extras to get out of this.
- Cydia app flashes and closes instantly when I touch the icon, why?
This error usually appears when you’re not starting your iPhone in “boot-tethered” status. Check the step 10 in article to fix it and re-enable Cydia.
