Messed up with internal partitions on my device

Hi,
How it happended :I wanted to just Overclocked the CPU of my Swipe Monster tab XL916,and as a consequence my device got hanged .I rebooted it and it was still working but it had no User apps in it.

What happened:It was a strange when I checked out in Setting>Storage that now i had two internal storage partition(Strange)....One partition was just 16 mb( i call it the artificial internal storage) and other was The Other was the actual partition which was 5GB in size.Now its considering the 16 mb as the actual internal and assuming the actual internal memory as sd card(although i also have a addition external sd card on my device that is 8GB in size).

As a reult of which:Thus i could only install apps which actually get installed on sd card (or which can move most of its part to sd card for eg mx player).And also these apps get removed on every boot :(.

What i think could have happened:Maybe it could have changed some system files which led to changes in overall system partition table. I am seriously not able to understand what has went wrong with my device.Please help in in settling these changes to internal partitions.

Extra Info:One more thing have come to my notice that when i install some apps to the system memory(using adb push) it reflects in the artificial internal storage as well.(it becmae 34 mb from 16mb)That means the artifical internal storage is none other than a part of system memory which due to some problem in partition table is being reflected as internal memory.If you need output of any adb command just tell me.

HELP. xposed messed up phone

so my phone is soft bricked. system UI has stopped, and won't load. i even did a factory reset, and the same thing.

i don't have a nandroid.

i tried to install xposed for lolipop 5.0, and this happened when i first booted. even did the uninstall, and it still happens. so no matter what, my phone won't boot.

did a factory reset, and it's still saying system ui has stopped.

wtf do i do now?!

safe mode doesn't even work. it just says safe mode and is a black screen.

I've got a messed up screen that happens occasionally

Hi guys,
Recently my Nexus 9 would occasionally give me a messed up screen with around 3x10 mm white or other color blocks piled up the entire screen. And flashing.
Sometimes even with shocking noises like biiiiiizzzzzzzzzzzziibibibibibibibizzzzz

It would disappear if I use the power button + volume up combo to force reboot.
Sorry don't have a photo or snapshot yet. I'll try to take one if that happens again.

That did freaks me out when it happened the 1st time.
It just pops out from no where. I've tried to locate where's the cause or the problem but failed.

I just wonder if this is some sort of hardware failure? It does gets quite hot after the screen is on for a while.

Please if anyone ever had the same issue?
And please please please do tell me it's not something wrong with the hardware!

Thanks.
