Hi,

This tool unlock bml5 to allow writing of kernel with a simple "dd" command.

You can find also a basic update.zip for CWM that :
- Make backup of the current current
- Flash new kernel

The bmlunlock tool is in kernel_updater.zip.

How to use :
Put your zImage in the update.zip. Then, use CWM and install zip.

This tool was made by Koush (Thank to him :)): http://xdaforums.com/showthread.php?t=767431
also Thanks to Supercurio for the updater idea.

if u got a BIG /data partition.. u hav to wait for a long.. sumtimes more than 10 mins.. **once i waited for ~20 mins..

**** ur sd card must hav enough space to backup the partition files & do the conversion & restore the backup.. otherwise ur phone will b SOFTLY BRICKED..!!

    I love that stuff! I'm waiting for it for e long time. Great job!
    Works really great ;)

    EDIT:
    One question:
    I have noticed that old kernel is backuped. How to restore it?

    Code:
    # cp bmlunlock /sbin
    # chmod 755 /sbin/bmlunlock
    # bmlunlock
    # dd if=/sdcard/bml5-zImage-kernel-backup.img of=/dev/block/bml5

    well ,i mean ,can i run dd command for every partitions?for example,if i hava a system.img,so i can run:dd if=/system.img of=/dev/block/stl6
    ???
    :D

    You could try ... I imagine that you build android and get image files and maybe you wonder how to flash them.

    what I understand (I could be wrong) :
    dd is a linux command that do low-level access on a block device. It send raw data.
    STL device, which is a layer over BML, is not meant to do such low-level access.
