Long story short, I have an Iphone 3G which is currently stuck in recovery mode that I know nothing about. I do not know the current firmware on it, and I don't know the baseband on it. The only thing I do know is the owner originally had it working until she attempted to update on Itunes (the phone was apparently jailbroken originally, method unknown). The restore error is 1015, and my attempts to kick the phone out of recovery with tinyumbrella did not work.

Can someone guide me on how to proceed? I have yet to attempt downgrading to a 3.XX firmware, which to my understanding might be a good start. Hoping someone can confirm i try this or provide a better alternative.

Put it in DFU mode and restore 3.1.3 onto it to begin with. If this is a 'downgrade', you will need to use TinyUmbrella at the end to kick it out of recovery. That should get you to a point where you can figure out the baseband, etc. If it's on 06.15, you'll need to use PwnageTool or redsn0w to strip the baseband out to make the recovery complete successfully.

Once you're there it should be a lot easier to figure out what to do.

Thanks for confirming that n1ck. I won't have time to try for another day or two but I will report back with the results.

hi i have the same problem. my 3g is on 6.15 and i have 4.2.1 on it.. its currently on recovery mode so all i get is a black screen i was able to kick it out of recovery and put it on pwnd dfu mode using ireb i then restore it using a custom 4.2.1 but when i get to the part where it says verifying i always get the error code 6. im not really familiar with all the tools i can use to get me out of this jam. can someone please help me. thanks

Are you making sure that you're stripping the baseband update out of the custom firmware? You have to do this in order to restore a 06.15.00 device.

can you give me a step by step process? how do i strip the baseband?

Please search, this has been detailed hundreds of places and was detailed in the documentation that was provided when you elected to install the iPad baseband. It's also detailed on the redsn0w site and on the dev-team's site. AND it's also covered on the forums hundreds of times, hell it's a sticky in the ultrasn0w forum.

ok... so im on 4.2.1. created custom 4.1 FW using snowbreeze without the BB update. hit Shift restore on itunes. went all the way until verifying restore then it gave me the error 6.... right now im trying to restore it again using the official 4.1 let you know what happens. if im doing something wrong let me know. thank you

oh and by the way im using itunes 10.1

ok so did the same thing used ireb to enter pwnd dfu restore using official 4.1 and im still getting the error 6 problem. really need help here..

The first thing we recommend when people have trouble while using sn0wbreeze is to use redsn0w. Though sn0wbreeze should work, when it doesn't, we recommend redsn0w. Beyond that, if you use redsn0w and make the custom firmware and still have trouble, read the 'Restore Problems' link in my sig and post your most recent restore log to pastebin as it details, then we can review that and see if we can make heads or tails.

the only i downloaded redsnow 9.9b9 i think thats the only one that can create ipsw for windows and as soon as i opened it . it said that it can only create ipsw for 3gs and 4. i am using 3g. so should i still go ahead and create ipsw with redsnow?
