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:

disable_uart3=0
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'.

You must be rooted to try the following, it seems you can't write to mtd0 without root.
Do step 1 again if you have to.

Also, SD card functionality has to work. For this, do 'fastboot oem enableqxdm 0' in fastboot mode.



Steps involved:

1. Find out your CID. Go into fastboot mode, and do 'fastboot oem boot'.

The log will say something like the following:

#INFOTAG:Ramdisk OK
#INFOTAG:smi ok, size = 0
#INFOTAG:hwid 0x0
#INFOTAG:skuid 0x21F04
#INFOTAG:hero panel = 0x0
#INFOTAG:engineerid = 0x0
#INFOMCP dual-die
#INFOMCP dual-die
#INFOTAG:mono-die = 0x0
#INFODevice CID is not super CID
#INFOCID is HTC__E11

In this specific case, the CID is HTC__E11.

2. Get the following mtd0.img from here or from here: mirror provided by SgtDavePwnage.

Edit this image to the CID you found above with a hex editor.

3. Get flash_image from here or from here: mirror provided by SgtDavePwnage.

Move this to /data/ , and flash the modified image using:

"/data/flash_image misc /data/mtd0.img"

You can move both mtd0.img and flash_image by putting it on your sdcard, and issueing the following command in a terminal emulator:

'cat /sdcard/flash_image > /data/flash_image'
'cat /sdcard/mtd0.img > /data/mtd0.img'

You might have to do 'chmod u+x /data/flash_image' before you run the commands (or chmod 755 /data/flash_image)



4. Repeat step 3 a couple of times if it doesn't seem to work well.

5. All done! Reboot, you should have normal usb connectivity. Post your 'fastboot oem boot' log and intermediate steps if it fails.

Redo step 1 of the rooting process. This will give you the required access

Doesn't it say "in fastboot mode"? You tried to enable fastboot in the menu?

[borgfather]

in the fastboot menu :

bootloader
reboot
reboot bootloader
power down

but no  "fastboot oem enableqxdm 0"

i also cant het into the recovery boot
it says

Legedimg.nbh
no image or wrong image!

hope you can help me

[Ale Baba]

Fastboot is enabled as soon as you start the phone with back key held down. Make sure ist says "fastboot usb" (which means the device is connected). You then need the fastboot binary to execute the above command.

To get into recovery-mode you have to launch the script provided with the rooting-package (e.g. recovery-windows). Currently there is no recovery mode, not even for rooted Legends, without pushing some files (which is done by recovery-*).
