[HOWTO]Do a backup of your current kernel and use it for recovery
This is a new device and the development is starting quickly. Many user that haven't the device is starting to develop some stuff for it also if they don't have the phone ( like me ).
Kernel testing can cause softbrick that can be easy fixed flashing again the stock kernel. The following steps explain how to do a backup of your current kernel so you can use it to restore your device.
It's a very simple guide.....
IMPORTANT You need to use adb ( also terminal emulator is good) and you need to be root!
dd if=/dev/block/bml7 of=/sdcard/boot.img
tar cvf /sdcard/kernel-backup.tar /sdcard/boot.img
IMPORTANT: Write the commands exactly like i wrote and put attention that in the second command. I wrote "BML7" not "BM17" but you have to write without capital letter so "bml7" OK?
After this you'll have a file called kernel-backup.tar in your SDcard. Save it and, in case of softbrick testing a new kernel, put your phone in download mode and flash it with odin (PDA field).
