[One (M7) Q&A, Help & Troubleshooting] dispereo:
Here my "logfile" of what I have done and it doesn't work. Please have a look to see where I went wrong.

Don't forget, as I am new to this, even the repeating procedures I wrote down, to make sure nothing goes wrong.

< achieve S-OFF >

•	Boot into OS

o	echo -ne '\x00' | dd of=/dev/block/mmcblk0p7 bs=1 seek=4265988
