As most of you know, people have been hard at work to fix the USB issues we've been seeing due to recovery setting us into USB debugmode.

After unsuccessful attempts to change the kernel commandline , eg. to:

board_bravo.disable_uart3=0
board_bravo.usb_h2w_sw=0

we've been successful in discovering (with the help of XDA-developers) that these switches are stored in the first NAND partition, mtd0, or 'misc'.

Step-by-step guide

1. Follow this r5 rooting guide to do Step 1 of the rooting.
That will give you a basic ROM to work with, with root capability.

2. Enable the SD Card functionality. Boot your phone in FASTBOOT mode (back + power), and enter this command: 'fastboot oem enableqxdm 0' . This will re-enable your SD card.

3. Put THIS update.zip on your sdcard.

4. Power off your phone. Hold Volume-Down + Power to turn it on, and select Recovery.

5. When in the screen with the big red exclamation mark, Hold Volume-Up + press Power, and select apply sdcard:update.zip.

6. This will automatically fix your MISC partition with the correct CID. Reboot, and your done!

It's nice having a fully-functioning phone back.

plz just refresh the first link to misc.img

[stevebrush]

the misc.img link seems to be brocken...

[StuMcBill]

This is great work, well done to all involved.

I have a question though. Is there a way you can dump your own mtd0.img file to be restored if you are not bricked atm?

Or is this not necessary?

DONT USE THIS FOR YOUR LEGEND THIS WILL END IN A FULL BRICK I THINK!

Wait for a modified misc image for the legend.... this will only take a few hours i think.

People, if you have a different CID and need to hex edit the file, share here and say also for what CID is edited.

[jdouce]

guys with legend
get a rooted non brick to get you the misc
use hex editor the same
do rest in the same way

Then post a misc partition dump.

'cat /dev/mtd/mtd0 > /sdcard/mtd0.img'

We'll see if it's similar.

It would be best to pull a misc.img if you're not bricked right now. It would also be best if a nandroid backup would pull misc.img during a normal backup.

To get your own misc.img out of a working device, use

cat /dev/mtd/mtd0 > /sdcard/misc.img

And pull the misc.img off of your SD card next time you link up.

is it for linux only (flash_image) ?

Hi r&a,

flash_image needs to be run from your phone (so yeah, linux only I guess, heh).
Copy it over to /data before you run it

[madmic]

You guys are legends

A few questions:

1) first post says you need ROOT to flash this repair - so what happens if you 'brick' first time during the root, can you still apply the fix??
2) what happens if you do brick? do you repair and try re-rooting again? Would be interesting to know if you re-brick, this would point to something about the phone causing this
3) now we know what caused the brick, can the original root be modified to prevent it?

Credits to Paul for the root and those who resolved the issue, I bet there are interesting things to come from the debug mode very shortly
