EMMC memory might be dead?

Hello!
First of all, the diagnostic in the title was given by a guy on reddit so ignore it if you want.
My Nexus 7 started freezing and crashing a few weeks ago. Last week I decided to change the rom from a CM 11 m8 to cm 11 m12.
While writing, after sending the system.img, it stopped at writing the system. Decided to try again but first I loaded TWRP and wanted to wipe everything just to be sure.
Apparently, in the console log, there were a ton of errors "cant mount /data", "cant mount /cache".
Looked up some solutions and managed to reformat using a make_ext4fs command. The /data errors were gone but the /cache is still there.
Tried reinstalling a rom again and it still failed. Also I tried to install a rom via the adb sideload. I manged to get a CM 11 running but the freezing was still there.
Whenever I try to install a stock rom, it stops at writing system and it says FileWriteError or something like that.
The tablet has been put to sleep for a week now and today when I opened it in TWRP, the /cache error was still there.
If anyone is interested in the reason it froze, I managed to boot into safe mode and there were a lot of NPEs thrown by Keyguard Manager or similar to that.
Please help me!

umount of /system failed; so such volume

Hello,
I'm trying to install a custom rom on my note 4.
I rooted successfully, and installed TWRP through flashify.
First issue I ran into is that the phone got stuck in a bootloop after installing TWRP. All fine I said, it's cool since I want to flash a ROM anyway.
I downloaded the ROM for my device, and after I clicked factory reset and tried installing the ROM, I got the error
Code:
unmount of /system failed; so such volume
I looked around online, some posts said that it's fine, the ROM will install anyways, but that's not the case. The ROM didn't install (the process is finishing way too quickly), and I'm still stuck at bootloops.
I'm running TWRP 3.0.2.0 (newest version), android 5.1.1, on my note 4 N910H.
I have access to TWRP and to download mode, and I can move files between the PC and my phone using an external memory card.
PLEASE HELP ME :crying:

Urgent help needed

I had rooted my yu yureka and flashed twrp . I had installed lineage os 14 and had it working very smoothly. A few days back I updated lineage os on it and also flashed it's volte modem files after updating twrp . Now it worked fine for some days and then one day it starts rebooting every now and then . And yesterday it developed something new.
It starts with yu logo and then goes dark for a second and then again displays yu logo and then again dark and ....... Loop goes on. But if you start charging it , it stays stuck on the yu logo . Also when I try to flash some other version of lineage os , it exits installation with error code 7
Is it hard bricked ?
Please give some solution for this asap

Edit : Also if that's of any help , I am unable to use features of the twrp like installing zips and wiping without plugging in my phone because it shuts down while the process is going on

Somebody please help !

Dude the problem is of battery inserted. Change it and it would help .
A few days back I also had this problem. After changing the battery problem was solved.
To flash a clean room first wipe all partitions and then flash the image.

Installation of RROS-Q-8.5.9 results in 'failed to mount /vendor (no such device)'

Got an update notification on my nexus 6p with installed RR-P-v7.0.2 on it. After installing this OTA update i got an infinite booting screen. I loaded back into twrp and got a password prompt to mount partitions (i didn't have any passwords anywhere on my phone before). I could neither access internal storage from within recovery, nor from pc. Installed newest version of TWRP (3.4.0), didn't help. Did a full wipe, which finally helped and allowed me to see and transfer files to my internal storage. Downloaded RROS-Q-8.5.9 zip from official site, tried to install again, which resulted in same error as before. Then i found out that i can load the system even with this error presenting, but i CAN'T install magisc. I don't know if it is me, who does something wrong or is it error in system zip? Also before each attempt to reinstall RROS-Q-8.5.9 i see logs, that magisc binaries r missing, i don't know if that might be the reason of vendor error in the end. The only way i can fix it is flash official vendor.img and flash older system image. But i really want to have RROS-Q-8.5.9 on my phone, with magics. So i came to seek your help, people. Please help
