I accidently ran the limera1n on my unlocked iphone 3g, then as I was aware that I have done wrong I disconnected it from my PC while limerain was indicating my iphone was in DFU mode…., then I tried limera1n to recover it from DFU mode, but I wasn’t able to fix it and it had permanently stuck on apple logo. Then I tried unbricking. Then tired above method, with many PC restarts and plug-ins plug-outs of iphone, eventually I was able to complete the process, but on thirteenth step after some installations with pineapple cartoon, I again stuck on apple logo. Then I tried redsn0w again to use the option “just boot tether….etc.” but then I have stick again with a new pineappleeev logo. How can I go back to normal?.

You have to update the baseband to 06.15.00... Read carefully this tutorial, here it shows you how to do this while jailbreaking

Check this site for 3G unlock. I was able to successfully unlock my 3g with 5.15.04 baseband where it will upgrade to 6.15 baseband and unlocks it. After going through so many trials from various sites, this is the the site which gave the right version of the redsn0w file and unlocked fine. . http://www.kittyra1n.com/jailbreak-and-unlock-iphone-3g-4.2.1.html I was executing on Vista. I did not use run as administrator but changed the affinity to use CPU1 only and it worked like a charm. I had previously had issues where it closes during ipad baseband fetch and not responding etc during downloading to iphone etc. This has finally worked.

Im sure you guys get people asking these things all the time but for starters I have a Iphone 3g on 4.0.1 and BB 5.13.04. Can I use this tutorial and just dont use the iPad BB, will I still be able to unlock it with the BB I have? Also if I download the firmware in your link will that update the BB to something I dont want?

I have iPhone 3G with following config and want to unlock the same. 1) iPhone 3G 2) Bootloader Ver : 6.02 3) Baseband Ver: 5.15.04 4) iPhone OS ver: 4.2.1. if i jailbreak the iphone with Redsn0w and upgrade my baseband from 5.15.04 to 6.15.?? , i suppose that, i will be able to unlock the phone. But after jailbreaking and unlocking, if i press restore button on iTunes, what will be the future consequences ? will it be dead iPhone or i will be able to reprocess it to jailbreak & unlock ?

You can unlock your iPhone 3G by using Remote unlocking method . It is one of the safest method to unlock iPhones. You can get it from any of the online vendors like Onlinegsmunlock.com to unlock your iPhone 3g. it doesn't requires jailbreaking . If you update your iphone 3g after unlocking it, it won't gets locked again .

Questions: - If I RESTORE to the firmware I downloaded, will it wipe my phone clean of everything? I don\'t want to lose all my contact information, music, app data, etc - My phone baseband is on 05.13.04, NOT 05.14.xx or 05.15.xx, does that mean I don\'t have to worry about anything if I need to unlock, and simply choose NOT to upgrade to iPad baseband 06.15.00? Will it still be 05.13.04 after redsn0w jailbreak for the ultrasn0w unlock? Thanks!
