Continuos reboot issue in yuphoria after cm12.1 update

I have updated my yuphoria to cm12.1 and after that mobile is getting rebooted if i start downloading something. Wiped cache many times still probkem persists. Pls anyone help me....

Factory reset the only option left

Yuphoria stuck at YU Logo.
I had got notification for the OTA Cyanogen 12.1 Update and I had updated it. But even after reboot, the same 12.1 Update-notification would still appear again.
Later, I switched off Yuphoria to take out the External-SD-Card for data-transfer. Then when I switched on the Yuphoria, this Yu-Logo Boot-Loop Problem has started.
Now, My Yuphoria is Stuck at Yu-Logo on boot... and showing 'cannot mount partitions' errors when I boot custom-recovery twrp.
I have unlocked the bootloader.
From what I read online, I guess the memory partition-tables have got corrupted.... Now how can we solve this corrupted memory problem ?
I read about fastboot-flashing database.rfs or dbdata.rfs in some xda-developers Threads.
---------------------------------------------------------------------------------------------------------------
I tried flash-all.bat with latest Cyanogen Official 12.1 ROM signed-fastboot.zip file... but still stuck at Yu-Logo on boot....
I fastboot boot trwp 2.6 custom-recovery.img and installed Cyanogen 12.1 ROM signed.zip file from external-sd card. But trwp says cannot mount partitions '/data', '/system', '/cache' etc...
-------------------------------------------------------------------------------------------------------------
I ran the command e2fsck /dev/block/bootdevice/by-name/system in terminal.
Then this message came : 'superblock has an invalid journal (inode 8) ext4'
I entered yes for correction multiple times and the process completed....
But still stuck at YU Logo on reboot.... Please Help.
---------------------------------------------------------------------------------------------------------
I erased persist, then flashed persist.img.
Then I booted into twrp recovery, and adb sideload cm-12.1-YPG4PAS8A8-lettuce-signed.zip
The sideload started and then stopped with error : failed to unmount /cache ; failed to unmount /data ;
---------------------------------------------------------------------------------------------------------
I boot into twrp 2.8.7.2 from fastboot-mode using command : sudo fastboot -i 0x2a96 boot twrp.img
Selected Wipe → advanced wipe → selected data :
It shows :
Mount Point : /data , File system : ext4 , Present: Yes, Removable: No, Size:0MB, Used: 0MB, Free 0MB, Backup Size: 0MB
Then I tapped on change/repair file system → change file system → EXT4 → Swiped IT...
Error : Format Failed.
E: Unknown MTP message type: 1
Failed to unmount '/data' (Invalid argument)
Error changing file system.
Updating Partition details.......
Failed to unmount '/system', '/data', '/cache' (Invalid arguments)
....done
Unable to mount storage.
After 'Change File System' Failed, I tried 'Repair File System' and 'Resize File System' also... all Failed similarly....
Only TWRP 2.8.7.2 and lower versions boots successfully in my Yuphoria.
TWRP 3.0.0 will not boot successfully. The TWRP logo will appear and then show command errors, and the phone will restart.
Please help me reinstall OS in my softbricked Yuphoria.

TWRP --> "Wipe" --> "Avanced Wipe"
Mark only 1 partition at a time and try
"Repair or Change File System" --> either "Repair" or "Change File System" (Most commonly "Ext4" but depends on phone)
What is your specific phone model?

Actually the problem is that the storage is showing 0mb and whenever I am doing anything like flashing other rom or trying to format any of the data ,cache or internal it says unable to mount. Even l have tried QFIL to flash the firmware but it's also failed. Please tell me something.

Is the stock recovery working?
TWRP 3 already tried?
Possible simple solution: but you will LOSE EVERY FILE on userdata.
Step 1: Install TWRP
Step 2: Go to Wipe box
Step 3: Select Advanced Wipe
Step 4: Check "DATA" and tap on "Repair or Change File System".
Step 5: Tap Change File System
Step 6: See original format on file system (EXT4). So turn to other (e.g. ext3) and switch back to original
Now /data is mounted back.
You can also try to erase the partitions using fastboot commands
fastboot erase cache
fastboot erase system
fastboot erase userdata

I have done all these several times and as you have said that change ext4 to ext3 then revert to original. I have done this and it is changed to ext3 but not coming to ext4 again. When I restart my phone then automatically they are changed to ext4.
And yes I have also flashed stock recovery and it is working. But now I am in TWRP recovery.
What should I do now???
Images are attached.

format data (yes) - backup your internal storage before you do so

How do I do that?

As for the backup manually copying folders you need to your PC is your best and safest option. That is if your version of TWRP supports MTP. Just connect your phone to your PC when in TWRP and it'll be shown as removable storage. Though if your device is encrypted you won't be able to do this.
To fix the bootloop: on TWRP home screen choose WIPE then FORMAT DATA (bottom right) and follow the instructions.

Phone no longer has OS and having trouble installing custom rom

Hey guys, hoping someone can save me from having to buy a new phone. I either need to fix it quickly or replace it quickly cause my job depends on having one.
I have a Moto 9 g plus.
I wanted to root my phone for a long time and today I decided to try since the Android 11 update ****ed up the camera on my phone anyway.
I followed this guide here
Root Motorola Moto G9 Plus Android 10 using TWRP and Install Magisk
When you have Stock Android on your mobile, You are almost free from bloatware apps. Even if your manufacturer put some apps, You can get rid of them in
www.androidinfotech.com
Everything seemed to be going well except that I couldn't get magisk to install, I kept getting errors in twrp.
I ended up installing the apk for magisk and used it to modify the boot file. I installed the image in twrp and on reboot, it went into a boot loop. I could go back to trwp and after swiping to factory reset, it broke the loop when I restart the phone. The problem is that now it just goes straight to the menu that you normally need to press and hold down and power to go to. I never did get to confirm if my phone was successfully rooted or not, I'm guessing no, and that that is the main problem now, as the phone won't boot up to where I can use apps, and if it isn't rooted, from what I understand, I can't install another rom?
Also, whenever I'm finished with twrp, when I press to reset it says something like "Phone no longer has OS, are you sure you want to reboot?". I read it is from wiping the data or factory reset, but I didn't actually wipe any internal memory, I can still view all files on it and on my sd card.
Maybe you guys can confirm my suspicions that I just ****ed up my phone for good or not.
This is what the error says when I attempted to install a rom, I tried with lineage and arrowos and I don't believe the problem is with the roms.

Thanks to anyone to offers any suggestions, this is my first time attempting this, so don't assume I know anything, I just step by step tutorials and usually don't have problems like this.
