    Did you mean to say 4.2.1 instead of 4.1.2 firmware version?

    Everything should be fine if you updated the 'newer locked baseband' to the 4.2.1 ipsw using the iPad baseband 6.15, except for the known issue with GPS not working on this combination.

    SpookeyET mentions throughout the forums about avoiding 'cydia' apps that are not needed and/or may be crapware etc.

    Likely a restore to a downgrade using a custom *.ipsw in DFU mode may be your only hope at this point. You need to post more details about the sequence of events that were involved in the upgrading/jailbreaking/unlocking etc... and not your generic "something in cydia that crashed the phone" ...

    Good luck

    You can restore to a stock firmware (4.1 if you have SHSH or 3.1.3 without SHSH). When you get the 1015 error use tiny umbrella to exit recovery. For restoring to 4.2.1 you would need a custom firmware with no baseband update in it.

    you wont be able to restore - i bet it is freezing at the end where it says updating firmware??

    This is because the newest firmware you are trying to install that apple offers is lower than what you put on..

    Let me know, i am screwed too and I am sure this is the problem.

    Okay, I may have figured this out. Been dealing with the same issue on a friends 3g. I had to use Sn0wbreeze 2.1, simple jailbreak of 4.1. I was then able to use redsnow to jailbreak a custom 4.1 and get it to take finally. I now have this phone working. Hope this helps.

    You need to restore it after using that setting.

    Hey guys I could also use some help. Here is what happened to my iPhone 3G.

    1) Jailbreaked and updated to 4.2.1 with BB 6.15
    2) Ended up wanting to reset my phone so I tried to restore it with a custom FW 4.2.1 w/ BB 6.15
    3) Phone got bricked midway through restore.
    4) In a state of panic I restored it via iTunes using the restore button and the normal 4.2.1 non "cooked" version.
    5) Midway in restore, error occurs and phone gets stuck on Plug Into Itunes mode.
    6) I'm still in a state of panic because I think I just bricked my phone.

    So my question is...what do I do to actually restore my phone to 4.2.1 again with the new baseband? I don't care about the unlock because I only needed it when I was out of the country a week or two ago.

    You need a custom firmware without the baseband update in it to restore to.

    You can only downgrade your baseband if you have a 5.8 bootloader 3G. Find out with f0recast or tiny umbrella.

    According to f0recast I have a 5.9 bootloader on my iPhone (BB 6.15; 4.2.1). Does that mean I'm SOL?

    It also said it was jailbreakable but not unlockable. Right now it works, and is both. I don't want to mess around with it unless I'm sure it will still work afterward!

    Yes, that means you cant downgrade baseband.

    So I'm stuck in a similar situation...

    I unlocked and jailbroke my phone with redsnow. I was on 4.2.1 so when I did that I upgraded my baseband to 6.15.

    I decided to clear my phone. I used the erase option in the phone. I left the phone to do it. After three hours or so I decided that the process had failed.

    I tried to put the phone into DFU mode but that wouldn't work. The phone will not pull up on iTunes.

    So now my phone is stuck showing the apple logo of death....

    Any help with this would be great...

    You will have to put it in recovery or dfu to restore. As the long as the buttons work you should be able to do it.

    I used the latest version of sn0wbreeze, as I am on a PC, and created a custom 4.1.2 ipsw then downloaded ultrasn0w 1.2 to unlock. All is working great on tmobile. 4.1 would always crash on 3G. 4.2.1 is still not as responsive as 3.1.3 but very useable and worth the stability and extra features.
