Soft Bricked after reverting from Jelly Bean update

[d4vr0s]

I'm hoping someone can help me out of this and I won't have to go to Verizon. I did a dumb thing, some background:

I had ICS with one of the patches they came out with later.
-Tried flashing to JB and it failed on file verification.
-Used Matt's 1.82 utility to put the phone back to stock ICS, but forgot to root
-Updated to JB
-Upon reboot, realizing that I forgot to root first I thought, hey I'll just go back to stock ICS and start over. Big mistake!
-I tried reverting back with Matt's 1.82 again and it failed on flashing the boot.img, so I tried using RSD Lite and the ICS SBF files and it also fails.
The error I'm getting when trying to write boot.img is "(bootloader) Preflash validation failure" So now I can't boot ICS nor can I reapply the JB update.

Anyone have any ideas on how to either get back to ICS or get JB working?

Way beyond my knowledge, I think you need the jelly bean fastboot files which might not be available for quite some time

From what I understand you can't go back to ICS from the JB leak yet... and I think the above poster is correct, there aren't any fastboot files available yet... beat bet is to take it in and I hope Verizon goes easy on you.

That's what I was afraid of
Thanks for the replies

d4vr0s I'm afraid you are stuck. Unfortunately, once you flashed/updated to JB there was no way to go back to ICS, for right now. You're going to have to wait until the fastboot files for JB are released/obtained. One of the warnings that should have been explained to you where ever you got the JB download was that once you installed JB there was no going back to ICS until the JB fastboot files were obtained. I may be wrong but I think you are stuck for right now.

I have an idea if I can remove the asset checking of the boot in the JB update, it might let me reflash. The problem is I don't know how to resign the update file after editing the script.

i did the same thing, and i thought mine was toast . mine would not even boot back up the screen would flash a light for a second, then nothing i kept trying to boot it into
stock recovery, by holding both volume keys and the power button after about 20 min of trying it finally booted into stock recovery, and i did factory wipe, then cache wipe then reinstalled the jellybean update that was on my sd card from factory recovery and all is good once again...

I've tried that multiple times, the JB update fails with apply_patch_check on EMMC:boot

My question is do you know someone with another cell phone that can download the jellybean file onto their sd card? Cauoif you do you can take your sd card out, replace it with there's then install jellybean. Same thing happened with me and this fixed my issue.

What Jellybean file are you referring to? I have the update on my SD card already.
