After receiving a few messages from some readers this weekend about what to do if you’ve accidentally / not knowingly upgraded a 2G iPhone to the latest 2.0 firmware. While I had not thought about this happening myself, I just decided to search around the web for some clues and I believe at the moment the method below should be the best choice if the above situation does happen to anyone out there.
Just to let you know first of all, the method below is entirely unrelated to any new release of jailbreak software by the iPhone Dev Team because they have not actually released any updated version of their Pwnage Tool for the iPhone OS firmware version 2.0 as yet.
According to dailyapps, at the moment this method is the best way to get around your problem and if you follow the instructions correctly it should allow you to restore 1.1.4 on your iPhone and unlock it too. It’s based on using the items below, however, I should stress that this method only works for Mac users and NOT Windows users. Unfortunately Windows users will need to wait just abit longer but that should be available soon.
So before I link you over to dailyapps for the exact instructions, it is advised that you have the following list of programs downloaded and ready, again, proceed only if you are a Mac user!
- iTunes 7.7 (from Apple)
- iTunes 7.5 (from Apple)
- AppZapper
- iPhone 1.1.4 Firmware
- Pwnage Tool 1.1
- iPhone 3.9 and 4.6 Bootloaders
Once you have downloaded the list of programs above, click here to head over to dailyapps for the rest of the instructions, the whole of the downgrading process and unlocking should only take around 15 minutes.
Update (27/07/2008): A concise summary for your latest iPhone jailbreaking and unlocking needs has now been published, click here to visit this post.
tnx a lot for the quick response…im now askin a friend who’s a mac user to look into it..but i need to know if we’ll be able to unlock it using mac, will i be able to use it usin vista or do i have to use mac..sorry, dont know much about tech things just got very excited and bought it…hope to hear from u soon…tnx alot..
Hi, well at the moment using the method in this post I can confirm with you that if you have a mac and follow the steps you WILL be able to unlock it again at firmware 1.1.4. If you are a Windows user, XP or Vista, you will need to wait abit and we will update you when this is ready, we’ll keep an eye on this issue. Hope this helps.
how can i unlock d iphone plzz send me the details on devz_shanky@yahoo.co.in
Hi, which firmware version are you referring to?
2.0 back to 1.4 is possible with windows! Downgrade baseband in DFU and after install only apple logo will show op.. Then hold power/home for force reboot in restore and restore to you own created 1.1.4 with both bl and let it downgrade to 3.9.. Press shift and recover in itunes.. You’re done.
You just need iTunes 7.5 and the 1.1.4 firmware image to downgrade. Force it into DFU mode, and restore to 1.1.4 firmware in iTunes.
I agree with John

is 2g the 2.0 firmware
@jake
You can think of it this way, 2G is the ‘old’ iPhone and 3G is the latest one. While firmware 2.0 is the latest version of the firmware and both 2G and 3G iPhones can have it following an upgrade. We suggest you use this link: http://blog.gadgetlite.com/2008/07/24/roundup-jailbreaking-unlocking-iphone-20-2g-3g-far/ to find out the latest information you need on jailbreaking or unlocking your iPhone.
how do you do this process with windows?
I have an (old) iphone 2g and it is unlocked not jailbreaked. I downloaded the new update and it wont allow me to use it anymore. I need to know how to downgrade to how it was before. can you help me?
I’m stuck on downloading itunes 7.5 because I can’t find where to download
Hello, are you sure this is what you want to do? This downgrade was originally designed because there wasn’t at that time a tool to jailbreak and unlock the iPhone 2G on firmware 2.0, but we’ve now moved on much further than 2.0. Anyhow, if you know what you’re doing and this is what you need, we’d be happy to help, iTunes 7.5 can be downloaded from: http://www.oldapps.com/
[...] which meant that your iPhone became either no longer jailbroken, no longer unlocked or even both. This is not the first time this has happened and I don’t think it will be the last. Its because its so easy to press yes [...]
