These are instructions on how to jailbreak your iPhone 4 on the 5.0 firmware using RedSn0w for Mac.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock. Please wait until we have posted a tutorial on how to update to iOS 5 using a custom ipsw if you need an unlock. The jailbreak is also tethered which means you will need to connect your device to the computer each time you reboot. Finally, it may be prudent to save your SHSH Blobs by following this tutorial before continuing.

If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.


Step One
Create a folder on your desktop called Pwnage

Download RedSn0w 0.9.9b5 from here and place it in the Pwnage folder. Likewise, download the 5.0 firmware from here and place it in the Pwnage folder. (Note: you do not need to download the 5.0 firmware if you are already on iOS 5.0)

Extract the RedSn0w zip file by double clicking it.

Connect your iPhone to the computer and launch iTunes.

Hey, I have my iPhone 4 GSM on 4.3.5 with Gevey, I want to put it on 5.0 (without jailbreak) but I can't do it like in the tutorial. iTunes gives me the "not ilegible" message or anther 1XXX error. I've tried downloading from different sources, using Tinyumbrella, different versions of RedSn0w, updating iTunes from 10.5.0 to 10.5.1... everything but I just can't. Any suggestions?

Use tinyumbrella and uncheck "Set hosts to Cydia on exit."

Done that at the first time but didn't work :\

I upgraded to IOS 5.0 keeping my baseband 0f 4.10.? and unlocked using Redsn0w. I downloaded a program from Cydia. When installing, the phone never turned back on. It got stuck with the Apple logo on. I attempted to use TinyUmbrella to get it out of restore state. That didn't work, so I tried to restore in iTunes using the custom ispw that I had previously upgraded to 5.O on. I received an error message (1600) that my phone could not be restored. I attempted to jailbreak and install Cydia again. It went through all the steps and said it was done, but I am stuck with a black screen with a bunch of steps ending on :Applem2ScalerCSCDriver:Added framebuffer device: AppleCLCD id: c7da5000 with the curser on the next line. How can I get my phone working again?

I seem to be striking out. I jail broke my phone with the latest version of redsn0w and I downloaded an SMS tone in Cydia and when it rebooted it put me into safe mode. I tried exiting safe mode, which put me right back in it. I tried re-jailbreaking and got the same result. I even tried restoring my phone and iTunes gave me an error and left me still in safe mode. I am at a total loss. Please help if you can

rs6er - December 16, 2011 at 1:33pm
By safe mode, do you mean DFU? If you only get as far as the Apple logo, use redsn0w and click "Just Boot."

Yes, I've done that twice. Any other suggestions.

If you find yourself in safe mode, just tap on the "safe mode" text at the top of you phone. You should be given a choice to reboot your phone. You can try jailbeaking again. They released the a new RedSn0w yesteday, so perhaps it will work better for you. You can also go watch the step by step video I made: http://www.hacksmods.com/2011/10/iphone-4-ios-5-jailbreaking-using-redsnow/

Issues after jailbreak: Can't connect to Youtube, Push Notifications keep popping up for every app, some apps from 4.0+ won't work.
DazexONE
DazexONE - October 18, 2011 at 1:29pm
That's odd. It works fine for me. Try a tethered boot again to see if it clears up your issue. Many people forget to do this after the jailbreak. Otherwise, try jailbreaking again with the new version of RedSn0w that was just release. The notes said you can rejailbreak on top of the existing jailbreak.

Hey! I jailbreaked and installed Cydia with no problems at all. However, I'm stuck in Safe Mode. I haven't installed anything in Cydia yet to cause these problems. Anyone with similar problems?

Use redsn0w to Just Boot.

daryoon - October 14, 2011 at 4:34am
You are incorrect about what a tethered jailbreak is. The only time you need to tethered to a computer is when you reboot or shutdown your iPhone. I don't know about you, but I never need to do that in my day to day life. Tethered jailbreak works perfectly fine. Please go read up on it and understand it a bit more.

DazexONE
DazexONE - October 18, 2011 at 1:33pm
Works fine for me. Most people forget to do one final reboot after the jailbreak process has completed. You Need to do a Boot Tether one more time. Watch towards the end of this video for instructions: http://youtu.be/US3zDfG7VmE

Why bother with this specific Jail break? Is there any important advantage over the Jail break on the current unthethered jailbreak? Nir Hus

iClarified_AC - July 28, 2011 at 4:44pm
first open up redsn0w and put ur iphone in pwned DFU mode, now open up tinyubrella and start the TSS server. Now download the 4.3.5 IPSW and shift click on itunes to restore. when you get the conncet to itunes you will need to install cydia under redsn0w 0.9.8b4. in order to install you MUST download the 4.3.4 IPSW and jailbreak/tethered boot with it, remeber NOT 4.3.5 IPSW, but 4.3.4 instead.
