iPhone 3GS (05.13.04) -> 4.2.1

[furi0n]

I am also 3GS old bootrom BB5.13.04. How can I upgrade to 4.2.1 preserving BB using windows?

From what i've read, the short answer is no. There is no equivalent pawnage tool for windows (4.2.1) bearing in mind the pawnage tool released is by no means an official release.

hey Furi0n, I think that I will follow the same way that you dit but I have a doubt. My Iphone needs Hacktivations because I don't have the original Sim card. Will I be able to Hacktivate it using Redsnow? To install Ultrasnow first I will need to hactivate it to enter into the Iphone. Can anyone confirm that is it possible to hacktivate the Iphone using redsnow after using Pwanegtool to update to 4.2.1 without updating the baseband? Thanks!

Redsnow now incorporates a new function option - deactivate

Select this option to Hacktivate iphone.

Redsn0w beta6 deactivate option removes hactivation so SAM can officially activate.

Thank you very much, I wanted to jb my iphone with the latest firmware for a while now but was waiting for a release by the dev team, after a while I decided I should go looking for a jb with the currently available tools, but there were no straightforward guides, this guide however helped me a lot and I was lucky to have 05.13 baseband version and got my iphone jailbroken and unlocked with latest firmware, thanks again for your guide!

Hi Blackwolf

I can answer your question. [ONLY FOR 3GS users]

You will require 3 tools in order preserve your BB, unlock & jailbreak your iphone.

1. Pawnage Tool Latest version (Unlock EDITION)
2. Redsnow latest version.
3. Ultrasnow

1. [PRESERVES BB] The current Pawnage tool DOES NOT jailbreak the iphone - as in, it does not install cydia. This unofficial pawnage tool release from iphone dev team is to allow the phone to be upgraded to 4.2.1 WITHOUT upgrading your baseband, hence, it will preserve your existing BB.

Step B

2. [JAILBREAK IPHONE] Latest redsnow only works on 4.2.1 firmware, therefore, in order for redsnow jailbreak an iphone, you MUST HAVE 4.2.1 software, hence pawnage tool.

Step C

3. [UNLOCKS] Unlock the iphone using Ultrasnow in cydia.


Please BEAR IN MIND, this method is only applicable to those that have a BB firmware of 5.13.04 or below. THIS IS A TRIED AND TESTED METHOD, I JB my iphone this way - iPhone 3GS 32GB 5.13.04, OLD BOOTROM

For those with BB above 5.13.04 must upgrade to 4.2.1 official, then JB with Redsnow using the iPad firmware in order to unlock.

Please Note:

3GS OLD BOOTROM = UNTETHERED JB
3GS NEW BOOTROM = TETHERED JB
