Default Forcing fastboot

This is for devs that know how to get partition informtion from their device:

If a phone doesn't go into fastboot by command:

Code:
adb reboot bootloader
One must simply erase the boot partition using dd.

First you must have your boot.img backed up if you want to ever get out:

Code:
adb shell
su
dd if=/dev/block/path to boot of=/sdcard/boot.img
exit (type exit again if not out of shell)
adb pull /sdcard/boot.img
Now to erase boot partition and force fastboot:

Code:
adb shell
su
dd if=dev/zero of=dev/block/path to boot block
reboot
You are now in fastboot.
To get out:

Code:
fastboot flash boot boot.img
fastboot continue
This guide is missing parts of cmds because different blocks are located in different places for different devices.
