[One (M7) Q&A, Help & Troubleshooting] nkk71:
looks like your partition problems are back :( (very possible hardware problem)

the second option would be my next choice, but if you want to test something while you still have SuperSU installed:

Option 1

: i have never tried this app: https://play.google.com/store/apps/details?id=net.vinagre.android.emmc_check&hl=en

but it does have a "Test memory block" function

again

: i've never tried that app nor do i know if it actually works on the m7, so your choice

if the app freezes while checking the memory blocks, then it's likely a hardware problem

Option 2:

time to ruu back to stock (this will wipe everything from you phone) and restore everything (rom, firmware, stock recovery, radio and anything else you can think of)

here's the file: https://www.androidfilehost.com/?fid=23501681358544181

(it's an old Android 4.1.2 RUU)

okay, so the progress bar didn't go all the way, but the command reported "Successful" (check the command prompt output above, I've highlighted it in bold), so let's reboot:

rebooting into bootloader...

then select factory reset in bootloader

once it finishes, bootup the phone and use it as is, don't restore anything, just use it normally for a while, and see if you get any random reboots. you should/can download some apps, take pictures, copy some music... to fill up the memory -> the more memory get's filled the more likely you are to "hit" the damaged spot (if any).
