So, I thought I'd make some changes to system files on my H815T, but before I did I made a backup of my system image using Send_Command.exe and:
dd if=/dev/block/mmcblk0 bs=8192 skip=55296 count=529920 of=/data/media/0/backup.img
And the changes I made cause it to not boot (I thought there's a decent change they would). But I thought: No problem, I'll just rewrite the image I backed up using:
dd if=/data/media/0/backup.img bs=8192 skip=55296 count=529920 of=/dev/block/mmcblk0
And it seemed to finish successfully, going back to a # prompt, to which I type LEAVE
But once I did, it just isn't powering on at all. I tried removing the battery, and turning it on with only a USB cable plugged into it... nothing.
What happened?
