HOLY CRAP IT WORKED!
I'm a complete noob at this so let me address two things that I got stumped on that will hopefully help others out:
1.) Although the instructions tell you to type the two lines of code at first it looks like there's nowhere to type it in. What you have to do is find the root folder through what looks like a file explorer interface. Find your root folder and it should be blank. Tap the row under "Up A Level" and you will see a row highlight briefly. After you tap the row, click select on the bottom right to start inputting your code. DOUBLE CHECK your code, and if you are a newbie like me TRIPLE CHECK it.
2.) I thought that this was an error message because it said "No space left on device". This is completely normal, just continue to changing
fota at the end to
misc and click go again. Afterwards, just exit, go back to the main menu and then reboot to system!
dd: writing '/dev/block/platform/msm_sdcc.1/by-name/fota': No space left on device
65537+0 records in
65536+0 records out
33554432 bytes (32.0MB) copied.
2.280673 seconds, 14.0 MB/s
3.) When you make your backup (and you should always as a precautionary step), if for some reason it says there is no space you can:
a.) Go to MOUNT in the menu you can
b.) Click on Storage:Internal Storage (should also indicate the amount of storage in MBs)
c.) Click Internal Storage (should indicate amount of free space)
d.) Click OK
e.) Now you're ready to make backups if you had an error regarding having no space to create a backup file.
