[X Play Q&A, Help & Troubleshooting] h0m:
Hello everyone!

First, I'm sorry for my English. I'll try to do my best to be clear and not too painful to read.

I post here tonight because my Moto X XT1562 is very messy. It's totally buggy actually.

The WHAT:

Some functionalities just disappeared. Here is some:

- Notifications aren't displayed at all. The notification bar stay empty, even when I swipe it down. Notification sounds are OK however.

- The quick settings panel isn't displayed... When I swipe down the right side of the top bar, there is only the notification bar who appear (empty...) like if I swiped down the left side. Nothing happens neither with a Nova widget for example to launch the activity corresponding to the quick settings panel.

- The Home button and the Menu app button do not works. When I touch them, they respond (they are circled by a halo and the phone vibrate) but don't produce anything.

- Some entries are missing in Settings like the entry to configure the quick setting panel. Also, some entries are displayed but when I touch them nothing happens, like the "Users" entry. Moreover, in "Backup & Reset > Factory data Reset" the "Reset Phone" button stay grey (unavailable).

- The "Developers options" menu isn't available neither. In this case, I had a toast with something like: "Developers options are not available for this user". In my actual configuration (spoiler: aka after flashing a new ROM), I can't activate the developers options at all.

- Probably other things but I'm not sure it matter. Apps work great however, even if there are now some force close. And just to be clear: it's not a touch screen issue.

So my phone is still usable, but it's not handy at all. Specially the fact that I can't go on the Home screen with the home button or switch between opened apps with the app button.

The WHEN:

These is happens after I try to move data that were on the sdcard in the internal storage through the built in tool in the storage settings. In fact, my sdcard (used like "internal storage") was almost full and my true internal storage with some space. I knew all my sdcard data could not go on my internal storage, but I thought Android could deal with that and will only transfer a part of these data. BUMMER. Anyway, during the process the phone had reboot and then the mess happens: internal storage was overfull, sdcard still full too, duplicate data were on both, etc. And of course, the previous bugs came. I deleted data manually (primarily pictures) and used the phone a couple of days like this.

Just so you know and because I suspect an perm issue, I have to add that a couple days before this episode, I also tried to create a second android user through the Users setting. But nothing happens after the asked reboot. I didn't insist.

The WHAT-THE-****:

- First, I was suspecting that the last boot didn't work properly because the internal storage was full. So after I made some space on the device I rebooted: nothing.

- After I delete all my pictures on the sdcard, I launch the data migration process to give it a new chance to finish properly. It did, but... nothing.

- I tried to wipe dalvik cache and the regular cache through TWRP: nothing.

- Like I suspected a permission issue, I tried to "Fix Contexts" with TWRP. Nooooothing.

- Very confident, I tried a factory reset through the Android settings but it was unavailable. So I did it in the bootloader. But... NOTHING!

- Well, I decided to flash again my ROM (XDRom) but I chose the last build to upgrade it. Flashing a new ROM replace most of the files so that MUST work. Guess what? Nothing!!

- Desperate, I tried to flash/upgrade the squid kernel. But No-****ing-thing... :crying:

I have no idea how it's possible. So if someone has encountered something similar or knows how that can happen, please, tell me.

I'm using TWRP, Squid Kernel r19 and the ROM XDR 24.107-52-5 (Android 6.0.1). Right now, my phone isn't rooted but it was when it happened. I was also using Xposed with Gravitybox and XBlastTools.

Thanks to everybody!
