I bloody knew it...I spent about 2 hours going back to 4.1 last Sunday and knowing my luck I guessed this would get released this week.
But then again I'm gonna hang on for 4.3 jb..4.2 isn't worth upgrading for..

IamMetaldave

Nice. Now all I need is a Mac :rolleyes:

do you need 4.1shsh blobs?i seem to have read somewhere this jailbreak can be used on "out of the box iphones"

corklad32

I think the steps in that tut are incorrect. Follow these to restore your iPhone 4 only to 4.2.1 while preserving your baseband.

then you've already done it

you can also download tinyumbrella which will save them locally for you as well

According to this if you're on bb1.59 on an iphone 4 and follow the instructions exactly you can unlock after upgrading

This jailbreak is horribly buggy on a 3GS, Took me atleast 5 attempts to get it to jailbreak and now I've finally got it the loader app doesn't think I'm connected to the internet...

Ricky91t

Although if the sources are hosted on their site that might explain it!

freeze4real

will this jailbreak work for iphone 3gd running on IOS4.2.1 baseband 05.15.04.

will it also work for iphone 3gs on firmware 4.2.1 on 06.15.00 baseband.

Done just now. Took 3 attempts to get greenpois0n to attach to iPad and deliver payload properly, otherwise all grand.

Connect to iTunes screen is wrong. There are three modes your iDevice can be in: Normal, Recovery (connect to iTunes) and DFU (black screen, used for greenpois0n). Are you following the countdown instructions to the tee?

I did have 4.3b, and if it's a fresh iPad you won't, but I don't think that's an issue for this release, and it certainly isn't what's holding you back right now.

Hmmm I turned tiny umbrella host off also might do a restore then try again

thanks

freeze4real

what is the difference betwen greenpoison rc4 vs rc5.

i thought rc4 also jailbroke ios4.2.1.

fox007

It's out for windows http://greenpois0n.com/

Stuxnet

not working for me
it goes through the motions, then hangs in verbose mode
tried running in xp compatibly mode, same thing ??

ip4, 4.2.1 fresh install

never had a problem with previous jb's ..this is odd


ETA worked after and computer restart !!

kudos dev team

freeze4real

its not working on iphone 3gs 16gb on 05.15.04 basseband.

Lmao_Man

Have a few questions about this :

Will it work on a 3G that's on 4.1 ? (not much point updating tbh)

And this 3G has been unlocked by o2 UK which is now being used on o2 Ireland.Using this jailbreak will be ok Won't it ? Don't want to end up having it locked.

Just want to be 100% sure as it's not my phone,I'm staying on my 4.0.1 jb :P

Stuxnet

this jb requires you be on 4.2.1 before running it
you can preserve your baseband using tinyumbrella, this is important if you need to unlock a phone

if you want to jailbreak a 4.1 3G without updating use the redsn0w tool instead

mgsrocks

I'm gonna give this a shot today. At the moment I'm running a jailbroken iphone on ios 4.1.

I know doing an upgrade to 4.2.1 from a jailbroken 4.1 is a bad idea and a restore needs to be done before jailbreaking but what do people do about backing up contacts/sms/save files?

I'm in the same boat, I will sync contacts int outlook, move important texts into notes and sync that with outlook and then restore to 4.2.1

Just did my iPad there and went great.

Conar

I updated from 4.1 to 4.2.1 no issues.
Did a backup first and a restore afterwards so all photos/texts etc still there. No issues!

Obskure

Just wanted to add my 2 cents here.
I've just done an untouched 3gs on 4.1. for a friend. Not so straight forward though. Perform a full back up before anything else.
1. Restored the phone to 4.2.1 firmware. (previously downloaded)
2. Use Redsn0w 0.9.6rc8 to install the ipad bootloader, v6.15.00. Do not install Cydia yet.
3. Use the new Greenpois0n for Windows and perform jailbreak for 4.2.1 as instructed.
At this stage, you are supposed to have the "Loader" on the home screen when the
process is complete, but it wasn't there!!! So...
4. Go back to use Redsn0w 0.9.6rc8 to install Cydia only.
5. Job complete!!!

One thing to note: for Redsn0w is & using 64bit Windows 7 and a quad-core processor(real or simulated),
start the program normally, and User Account Control will seek permission to continue. Do so!
When you get as far as the screen which is just before setting the phone in DFU mode, you MUST use task manager and click "show processes from all users".
Right-click on redsn0w.exe and select "set affinity".
un-check "all processors" and set "processor" 0 only.
Continue as normal to finish the process

Hope this helps some of you

I'm getting a lot of errors installing apps from cydia. Script errors resulting in an option to forcibly clear or ignore temporally. Anyone else have this problem?

jaykay2

I also was able to updatel my 3Gs from jailbroken 4.1 to 4.2.1 and then re-jailbreak without any issues. Used PKGBackup to backup, and then restore my apps etc.

Blazer

hmm..seems to be few issues so I'm not gonna bother updating my iphone yet (downgraded to 4.1 jb) but I'll give it a go on my ipad which came with 4.2.1

eeloe

I'm currently on an iPhone 4 with 4.1
with a baseband of 1.59.00

I NEED my unlock, and i can't really see anywhere that says it's 100% safe to do this for unlockers?

Also, is going through all this, to update to 4.2.1 worth the jump from 4.1?

I was in the same boat as you. Follow these steps exactly and you will be fine

Obskure

It's very possible. You should use tiny umbrella to upgrade to 4.2.1 while maintaining the baseband. After that, it's just a simple matter of using the new greenpoison. I did another iPhone 4 today, and its easier than the 3gs. When 4.2.1 no need for redsn0w as I described above.
Take care with tiny umbrella though. It edits the hosts file and you should research all possibilities if unsure.

I used Greenpois0n today to jailbreak my 32GB 3GS on 4.2.1 and Baseband 05.15.04, work fine and have not came across any problems thus far.

eeloe

I'm currently researching for apps that'll FULLY back up the apps I have on the phone from cydia and the app store.

I'd actually crack up if they were all lost!

I only came up against a problem because I was using the iPad baseband, 06.15.00 though. Will be straight forward for most.

PKGBackup my friend. Was in the same boat but was able to restore all apps last night after restoring and jailbreaking.

What's the deal with iPod Touches on 4.2.1? Do I need to worry about basebands and all that?

Obskure

No worries with ipod touch. Simple terms: the baseband is related to the mobile phone (cell) chip, etc.

that appears to say that i should already be on 4.2.1 before jailbreaking?

Garroldy

Hi guys, I need to unlock an iPhone 4 to use in Dubai. 4.2.1 baseband 03.10.01. If I run greenpoison will it unlock the phone as well as jailbreaking it.

Sorry if this is a lame question, I'm new to jailbreaking and getting confused by the options and jargon even in the stickies. I'm locked into three contract and moving for work at short notice. Thanks

Obskure

It is not possible to unlock that baseband @ this time.
Don't give up though. There is a rumoured unlock ready to roll out once Apple release the 4.3 firmware.
So all I can say is to hold out and don't update to 4.3 until you see a walk-through for unlocking and jailbreaking together.

naasrd

Just jailbroke the iPad, no problems what so ever. Job done in under 5 minutes. A fresh installation of 4.2.1 was recommended but I didn't bother.

Zapp Brannigan

Hey guys, planning on jailbreaking my iPhone 4 for the first time with greenpois0n and I was just wondering about people talking about unlocks.

I got my phone direct from Apple so it is unlocked, the jailbreak won't affect this, right?

Obskure

If you bought it through the Apple store, you're fine. Unlocks won't be an issue.
