Iphone Frozen after running BlackSn0w - HELP!

ok so i followed a tutorial for upgrading to 3.1.3 on iphone 3g 8gb, and basically i downloaded sn0wbreeze, downloaded the iphone 3.1.3 software, ran sn0wbreeze, let it do its thing, everything was working great, went to cydia, added blackweather to the source, downloaded blacksn0w to unlock for tmobile, during the blacksn0w install it froze with 2 circles in the middle of the screen so after 2 minutes of waiting on that screen i reset the phone (home button +power 10 secs, then let go power and wait another 5 seconds) anyway now my phone is completely fucked, it wont turn on, its stuck at the snowlogo aka applelogo and it just sits there for about 5 mintues, then the screen turns white for about 1 second, and it repeats, this is going on for 2 hours, itunes nor my pc will detect the phone at all, so i cannot boot into dfu mode, my pc wont recognize the iphone at all, i have tried every possible solution that i can find online, i think my phone is permanantley bricked. i restarted my computer, tried another computer, same thing, i followed all the steps to get into dfu mode, i mean ive done it in the past a bunch of times so im not doing it wrong, anyway, anyone have any CLUE what i can do? or do i have to buy a new phone. thanks.. mike

Let the phone go flat and try to get into dfu again.

It has been documented here and many other sites that blacksn0w does not work with 3.1.3/05.11.07 there is no word on when or if this will be fixed.

Sn0wbreeze is semi warez and is not recommend or supported by this forum. Use pwnagetool not an unauthorised and poorly tested windows clone.

i have the exact same problem, word for word, line for line.. i don't think u can use blacksn0w with 3.1.3 .. now my phone is non-respondent, itunes, nor does my pc even recognise it. I can't put it in dfu mode. I can't blacra1n it bcoz it can't read my device. I tried redsn0w which managed to do all it does and it seemed like everything was about to work again, but as soon as redsn01 finished doing it's thing then iphone went back to the apple logo, and it stays that way... WHAT THE F*K IS GOING ON. idon't want to buy another fone, why does apple hav to make everything so difficult!! can someone please help us

blackra1n and blacksn0w do not work on 3.1.3 and geohot has no plans to update them. How much more simply can this be stated?

Don't risk it, you will end up requiring a restore.

I have the sma problem. Please help me out if you could manage some how.

To get your phone to be able to restore again...
download redsnow, and choose the original 3.1.2 firmware...
follow instructions
wait til Iphone screen goes white
Unplug iphone
go into itunes and you should be able to do your custom restore

Well i did this lots of times but you need to enter recovery mode (turn off then hold home button whilst connecting to a computer) and restore in itunes (shift + restore) then sit back and let it restore. At the end it will say an unexpected error occured or something like 1015. now you need to download recboot (google) and make sure you have .NET v4 or it wont run, and open recboot and click exit recovery. it will not normally find a device in recovery mode but do it anyway. then it will restart and you have to connect to itunes and set up as new phone. then your done! N.B. it wont be jailbroken so after adding wifi or sorting out your 3g, open safari on your iphone and type in jailbreakme.com and slide it to jailbreak. after that it will add cydia!

Hope i helped

You can also use FixRecovery (from the same site as TinyUmbrella) or the latest redsn0w beta 0.9.9b1 to exit the recovery loop. A tool that performs such a simple function should not need to rely on .NET 4 runtime being installed that is OVERKILL.
