Untethered Jailbreak for iOS 4.2.1 with RedSn0w is Almost Ready! - iPhoneHeat

Untethered Jailbreak for iOS 4.2.1 with RedSn0w is Almost Ready!

According to MuscleNerd, Untethered Jailbreak for iOS 4.2.1 with RedSn0w is about ready. The New RedSn0w will not only jailbreak iOS 4.2.1, already jailbroken (tethered) users can use this new RedSn0w to re-jailbreak to get untethered support without any restore (all installed jailbreak tweaks will stay).



Note: This is a backup Unterthered iOS 4.2.1 jailbreak plan for those w/legit access to 4.2b3 IPSW. Comex will bring the original untethered jailbreak for iOS 4.2.1.

MuscleNerd: the backup plan for those w/legit access to 4.2b3 IPSW is about ready…again though, better to wait for comex

MuscleNerd: Thanks to comex, redsn0w can now handle much bigger files than ramdisk 25MB limit. Useful for “backup plan” 4.2 untether

MuscleNerd: it shouldn’t require a restore…just another redsn0w run. (That’s the goal!)

Comex is working on bringing an untethered jailbreak 4.2.1. This backup jailbreak requires 4.2b3 IPSW. A new code written by Comex also allows users to retrieve Photos and Files stuck behind an unfixable filesystem problem.

MuscleNerd: This latest @comex code also allows retrieval of photos+files stuck behind an unfixable filesystem problem…good stuff!

The iOS 4.2.1 jailbreak (untethered), if everything goes as planned, is expected to hit masses this Christmas eve. unlock for iPhone 4 baseband 02.10.04 / 03.10.01 is also expected in less than a month. We’ll keep you posted as soon as a jailbreak or unlock tool is out. Stay Tuned!

Heres a noobish question – Will i be able to get an untethered jailbreak on my Iphone 3GS with the new bootrom as well?

iPhoneHeat December 22, 2010, 3:54 am

Yes, for ALL iDevices

Cool thanks for the quick response – Yea i got a little confused with the mention of the 4.2b3 IPSW thingy but did a quick google search on that and figured that it has something to do with the developers etc etc but yea also figured that it meant like a universal 4.2.1 jb for iphones etc so thats cool –

Just curious what if I have 4.1 and updated to 6.15 to unlock. Can I still upgrade to 4.2.1 and use the jailbreak.

junjanic December 24, 2010, 10:53 am

after bb upgraded to 6.15, the phone can NOT retore and upgrade, I tryed, phone is dead, it can NOT turn on

Junaid December 24, 2010, 1:06 pm

Dear junjanic,

You can use pwntool 4.1.3 to upgrade to 4.1 or 4.2.1 without upgrading the baseband. I have done it so can you. Also you can use redsn0w 0.9.5b5 to do the same. Hope this helps as it helped me.

Hi. Do you know if I can use pwntool to jailbreak my unactivated, never-jailbroken 3GS (new bootrom) if it is currently on 4.0.2? I have the old 5.13 baseband on there so I would like to keep that baseband if possible.
