Upgrading your iPhone to 2.1 custom firmware

I have been holding off from posting about the new PWNAGE tool as initially both the 2.0 firmware and pwnage tool had a lot of bugs..

Few days back i pwned my oldest 1st gen 4GB iPhone to 2.1.. gotta say this firmware is very much stable and i can recommend updating to it.

Here’s how-

### only for 1st gen older 2G iPhone ###

• PUT your iPhone in DFU mode if you have never pwned before. Recovery mode will do will do if you are on 2.0/1.1.4 custom firmware currently.  Higher success rates with DFU mode
• download and restore the iphone 2.1 custom firmware using iTunes.

Recommended iTunes version:7.7

To downgrade to a 1.X.X firmware use itunes <= 7.5

Definitive guide to putting iphone in DFU mode. NOTE: don’t use software like ZiPhone or iLiberty for putting iphone in DFU mode, thats not the real DFU mode.

if you get errors during firmware flashing, look for error codes here and keep trying..at one point you will succeed :)

ZiPhone / iLiberty are useless for 2.X.X firmwares

AS of writing this post there is no real sim unlock solution for newer iPhone 3G, please don’t pay anyone for this..

Hacking the iPhone is my hobby, I am not a professional iPhone repair guy.

 

A lot has happened in last 3 months.. some of which may go to this blog if time permits :) http://aakash.me redirects to this blog now..
