I found what was the issue.
i was using paragon hd manager to create 3 partition. (fat32-1600, ext3-1000, linux-swap-540)
i try twice with this prg, still the same error when booting in recovery mode.
So i try with gparted software (linux based)
i redo the same partition and now the error is gone.
it seem that the partition was nor reconize correctly.

Facing problems while updating

My yuphoria running on 5.0.2 android lollipop
I received OTA update of 5.1.1 android lollipop but cant able to install it.
After downloading when i click on install update, the installation process does not start.
How can i slove this?

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.

Encryption failed - device will not work

Hi,
Im noob at this so please bear with me.
Ive got this Tab2 which will not work. Im interested in fixing it(if at all possible)
I have no idea what had happen to it prior to this error.
Problem:
When starting and went trhough the boot logo the device shows "Encryption failed" page.
with further text:
Code:
Unable to complete encryption due to interruption. Perform factory data reset(erasing all your data) before use. After resetting, try encrypting device again.
Tried:
booting into recovery and resetting data/factory, no result.
when entering recovery it says:
Code:
"installing system update, no command" and enters the recovery.
then it lists:
Code:
Android system recovery <3e>
under menu there are some errors:
Code:
"Manual mode"
e:failed to mount /data (invalid argument)
can't mount '/data' (invalid argument)
E:failed to mount /data (invalid argument)
E:can't mount /data/log/recovery_log.txt
and a lying robot...
--------------
when trying to delete/factory reset the unit
it show all ok:
Code:
-- Wiping data...
Formatting /data...
Formatting /cache...
Data wipe complete.
Rebooting gets device into previous "Encryption failed" page.
I tried to flash custom recovery with odin but even when saying pass it does not work, I cannot boot into either twrp or cwm.
tried the trick without rebooting and going straight to the recovery from Odin.
did try with sdcard and flashing the recovery but it fails to flash that way.
also tried to apply the stock rom with odin but it fails evry time.
is there hope for this tab?
please assist.
regards, DMB.

Forgot to add the device:
Code:
GT-P5100
3G
16GB

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.
