Backflip Brick Fix for flashing back to 1.5 from official 2.1

[dy_user]

For anyone not wanting to recompile an SBF and happen to have a US AT&T motorola then I have uploaded a modded sbf which is here:

http://www.mediafire.com/file/2qvczd...PRODUCTION.sbf

Download and flash with RSDLite

For the software (Depacker, MotoDrivers, etc.) here is the link:

For anyone else or people who want to compile for themselves then continue to read below.

I have seen some people with this problem so I decided I would start a thread for the solution I came up with.

Last night myself being very tired decided to flash from 2.1 down to 1.5 as some of you know from experience or from knowledge this is a very bad idea because the official 2.1 has an updated radio.img. After flashing you will most likely be stuck at the USBINIT screen. If this is the case this is how you can fix it to get back to stock 1.5 with the updated radio.

First download Moto-Depacker

Second find your SBF that you tried to flash to but now your phone will not boot.

Third Open SBF in Depacker and click Split to folder

This should create a folder in the directory your SBF was in with the name of your SBF

This folder will include a bunch of MBN files

Then extract the update.zip you have in a different folder

There is a file in update.zip (or your 2.1 soak) called radio.img make sure you know where that was extracted

In Depacker click on MOTOBLUR then Extract radio.img

This will create a folder in the directory radio.img is in called radio-extracted with a bunch of MBN files

Copy and replace the files from radio-extracted to the directory that was created when you hit Split to Folder

Example (SBF NAME)/

After the files in your split folder have been replaced by the files from your radio-extracted folders go to Depacker and click Open Files Folder

Find your split Folder and select it

After that you should be able to hit Compile File

After compiling there will be a folder created in your Split Folder called rebuilt

In that folder there will be an SBF file

Use that SBF file to flash your phone with RSDLITE

After Flashing your phone should boot normally

I have done this myself and it has worked perfectly well.

Good luck to anyone having this problem and please post issues, concerns, and anything else in this thread.

(For anyone confused on the NOTE: before in this post I had these directions attached to a list of directions for someone to flash using rsdlite.. forgot to remove it lol.)

Awesome work. You should upload and post a link to your repacked SBF for others just in case they don't want to mess with CG unpacking/repacking..

Good Job! This will be a great contribution for the community.

You're awesome man, just ran into this myself, thanks works like a charm. And weasel I don't agree, if a person went through and bricked the phone then the should have to take the steps to unbrick the phone, not have some one else do the work, and then complain if it doesn't work. And it's a really easy process.

thank you so much, i thought i killed it.... thanks again

would a nandroid 1.5 from when i first flashed 2.1 work?

[dscharmer123]

Thanks so much - this worked like a charm for me! I had the new update installed (2.1) and for a very dumb reason tried to downgrade. Your fix worked, and now it is booting!

Only thing was I could not find the update.zip file, so I used my most updated radio.img file from the newest update.

Thanks!

I'm glad it worked and the update.zip I was talking about was the soak. I just made the steps more generic lol.

Just got the links up for my modded SBF and all the software you guys will need.

Thanks lol.

dy_user; you might want to zip up the sbf to avoid corrupted transfers.. it'd cut the file size in half as well.

thanks again!

I was going to at first but didn't have time last night I only had a few minutes to start the upload before going to remodel a house. I wanted to get it out as fast as possible and will be re-uploading a zipped version later today.
