E: Unable to mount on hard reset screen and while wipe in twrp. Phone stuck on logo - Lenovo A6000/Plus Questions & Answers

I'm a noob here. Below is the sequence of events.
1. I was already running on low internal storage (No external sdcard)
2. Phone switches off due to low battery
3. Switched on after a full battery and got this msg-"encryption unsuccessful with 'reset all' button"
4. After few restarts stuck at logo screen
5. Tried hard reset (for factory reset)- getting E: unable to mount cache recovery log
6. Tried wiping cache system dalvik data through twrp- getting unable to mount data system cache error
Tried changing filesystem to ext4 but that didnt work. Tried checking other threads but couldnt find a similar scenario.
Thanks!

Ext4 is the default filesystem. Change it to fat and then revert back to ext4 again. It will repair your partition.

Tried doing that. I get a message-
E: Error changing file system
updating partition details...
E: unable to mount /system /cache /data
ONE MORE IMPORTANT THING- twrp shows internal storage as 0 MB and no OS installed.
I think I corrupted my partitions or something to do with encryption.

I tried cache and data partitions to fat from ext4.
Dalvik cache partition is something ghat is showing as- "file system options are not available for this partition"

Change data or system partition. If system partition shows 0mb in details section after tapping on 'change or repair fs', then change fs of 'system' partition.
But if data shows zero, then change fs of 'data'.

Both system and data partitions (and cache too) are showing 0mb size in details. I tried changing fs but arriving at the same error.
No matter what operation I try to do, i see unable to mount system data cache error lines coming up.

i am having same prblem i tried all this bt always got error unable to repair system data cache
i tried flashing qfil method not works still stuck on boot

use cw to partition the drive, search "partition" Its something like 2048 & 512 ..dont quote me on that though. Do a search, thats what I had to do to mine to bring it back

You could try using CWR to format the sdcard (internal mem). Go to Advanced and there should be an option there. I was getting this error at one point so I formatted with CWR and it seems to have resolved. I used the 4096M and 64M options when asked.
Then you should be able to flash whatever ROM you want with CWR.
Thank you Photonmedia for the help. I too had this problem and it was fixed with a format and re-partition. However, now I don't have a restore image on the Gtab. I know, I'm an idiot...Luckily, it finally booted back into CM6.1 and i was able to move a vanilla update.zip to the internal mem.

[Q] Yet another bricked defy. can't restore cwm backup

Hi,
well... what can i say... i bricked my beloved defy. =(
How it happened:
Since Quarx's CyanogenMod 7 i used several CyanogenMod Versions from Quarx und Epsylon until about 2 weeks ago. I had the CM10 (4.1.2) Version from 11.05. installed.
Then i saw Quarx new release from 16.06.
Before i flashed the new version i made a full backup with cwm 5.7.0. Then i installed the new version trough cwm. everything look fine. But there wen't something really wrong. After rebooting the phone got stuck even before 2ndinit. I tried it several times but the the phone wasn't booting any more.
I thought: no problem. I have a backup. Let's restore is quickly. The easiest way to me was:
- start the phone in bootloader
- flash a stock sbf with rsd lite (sbf: JRDNEM_U3_3.4.2_179-002_DEBLUR_SIGN_SIGNED_UCAJRDNEMARAB1B80AA03A.0R_PDS03C_UCAJRDNFRYORTCOREEU_P023_A008_HWp3_Service1FF.sbf
- root the phone with superoneclick
- install 2ndinit for defy (SndInitDefy_2.3.apk i think it's cwm 5.0.3.1)
- restore backup
but here the problem beginns trying to recover /system(log from recovery):

Error while restoring /system!
Problem while restoring system !
-------------------------------------------------------
i tried so many things like:
- install cm10 an try restoring with cwm 5.7.0 (same error)
- different stock sbf's (makes no difference)
- extracting system.ext3.tar and copying i to /system with adb (stops copying at about 50%)
and much much more... i forgot the rest ^^
the thing is.... i have no idea what exactly is going wrong. In my opinion it's here in the log: "Remount /system read-only". how should cwm be able to write the backup into system i it is mounted as "read-only".
im working on it since the last 2 weeks and it is getting super frustrating =(
Hopefully someone has better ideas than me? I would appreciate it.
At least: thanks for reading!
There are 2 possibilities according to me (I may be wrong:silly
1. Your backup might be corrupt -> try another backup
2. Your eMMC memory chip may be corrupt -> send your phone for service
TRY Wipe system cache and data then restore.
OR
Install CM10 with cwm (example 26 March build), restore only data, then dirty flash the latest CM10 (only wipe cache and dalvik). Old builds of CM10 can cause problems.

Thank you for your answer!
I believe the backup files are ok. md5 is ok and the recovery log says: backup ok, but internal storage.... is weired.
Maybe a fried eMMC. But how? And buying a new phone is sadly way cheaper than service.
I wiped cache and data endless times. But no luck.
Is it possible to wipe (format) system?
I installed different versions from cm10 and they are running fine. But i really would like to restore my backup. There's a lot of work in it. =(
Tried this also 2 times: http://forum.xda-developers.com/showthread.php?t=1807899
But with this method, the phone won't boot up and got stuck in a bootloop. Can't even see the cm logo. An it makes no difference what version of CM10 is installed.

Yes, wiping system is important in this case. The option is present on the main screen of CWM.

I would like to format /system. But how? I can't find this option in cwm (5.7.0).
- Reboot system now
- Apply update from sdcard
- Wipe data/factory reset
- Wipe cache partition
- Install zip from sdcard
- Backup and restore
- Mounts and storage
- Advanced
- Power off
- Exit Recovery
- Go Back
It is possible to format some unmounted partitions in "Mounts and storage". But if i unmount /system there is only the option to "remount /system" but nothing linke "format /system".

My bad. You can try Defy full wiper (DO NOT REBOOT AFTER FULL WIPE).

OK, somehow the devices are "busy" so the wipe script couldn't wipe. Although in cwm it said it was successful.
So i tried unmounting /system, /cache and /data before running the script. Here's what i got:

Is it possible to do something about the "busy" partitions. Whatever they're busy doing
Check out these threads, not sure they'll help - http://forum.cyanogenmod.com/topic/6433-solved-messed-up-partitions-on-internal-storage/.
AND http://forum.xda-developers.com/showthread.php?p=20707200
Your partitions may be in the wrong format.
EDIT - You can try starting from sbf, then installing your preferred CM10 release, and then extracting the backups into the respective directories using ES file explorer (only the files that you've changed).
EDIT 2 - Install CM10 with clockworkmod (not TWRP) and then go to bootmenu (press go back on the main screen of recovery), and then format system and data to ext4, and then try restoring backup. <------ try this first
why??
sir. i tried this 2 xperia ROM. my unit is OT 918n. i completed the installation of BRAVIA_LACV--Es_V4 & Xperia by Jarey..

:good::fingers-crossed:Thank you, i have a similar problem. My battery's Defy was completly discharge. Normaly, i plug my Defy, wait for 10 % charging, and i turn it on and i let the battery charging all night. But, i forgot to turn my defy on, and the morning when i turn it on, the cyanogen 7 logo bootloop.
I do a wipe system reset to factory, the defy turn on, and when i restore my backup, bootloop again.
I do what hotdog125 write, i was thinking its works, but it didn't.
I lost my data, :crying::crying::crying::crying: but i have a nice cyanogen 10 bootloop :laugh::laugh::laugh:
I finaly restore my defy with a backup do with recorvery when my phone make a bootloop.
I put cyanogen 7 and i found an application name Nandroid Manager http://forum.xda-developers.com/showthread.php?t=2044414 , 1,46 euros, that permit to restore all or a part of the backup you do.
I restore my apps, my sms, my mms, my call log etc... i want to keep. My contact was backup on my gmail account.
Like i saw it works, i put cyanogen 11 and redo the partial restore.
My defy was fine, and increased from mb525 to mb526 when i install Cyanogen 11.
I recommand when you have an android phone to root it, put an recorvery, put Nandroid Manager and backup with recorvery regularly, you could restore all your phone if you don't change your rom, or resotre partial data if you change your rom.
Thank you to your site.:laugh::highfive:

Bootlooping out of nowhere, cant mount /data

All,
I have a SM-G35FD which is in a bad state. My phone started boot looping one morning after it was fine the night prior (3 days ago now) and I believe an auto-update may be the root cause. I am trying to find any way to access the internal memory to recover data, however I am not able to mount /data or /sdcard. I have not done much with my phone besides adding root, no CFWs ever, and no custom recoveries (prior to today). Also, I lock my phone with my thumbprint. I did not go through any encryption setup on my device.
Details about the initial problem:
It started boot looping several times and at some point it shows a black screen with red text. after letting the battery drain (because I could not force reboot) i was able to get into stock recovery and wipe the cache and reboot; this led to occasionally getting to the security screen which would freeze 1-2 seconds after logging in.
Things I have tried (19mar2017)
got into stock recovery, wiped cache, rebooted. Freezes at security login screen
Installed TWRP to get more functionatity. Was able to install TWRP
used TWRP to try to mount Data, but it will not mount (only System, Cache, EFS, and USB OTG will mount)
used TWRP to wipe Dalvik and Cache only. Errors show "cannot mount /data"
used TWRP to install CWF, freezes during extraction (4-5%)
can use ADB to run shell
UPDATE 20mar2017: Ran "Wipe -> Advanced Wipe -> *Select System Partition -> Repair or Change File System" on /system. I think this was a bad move as now I can access the /sdcard folder and its missing all data. I didn't think it would matter since the options under Wipe show "System" and "Internal Storage" separately.
Perhaps data does not mount because it needs my thumbprint? Is there anything I can try to backup the internal user memory partition and my fingerprint signatures? any way to access the user data?
Thanks to all for their time!
I found a video ( https://www.youtube.com/watch?v=VJRKuQf0puE ) which suggest that I can use TWRP to "change the filesystem" for the /System (and other) mounts in order to fix the /data mount. This can be accessed using Recovery(TWRP) -> Wipe -> Advanced Wipe -> *Select System Partition -> Repair or Change File System -> Change File System -> Options { EXT2, EXT3, EXT4, FAT, exFAT, F2FS }. Since my goal is to recover the "User Data" partition, I would not perform this on "Internal Memory" but would on the other partitions. Hopefully this would allow me to reinstall the Stock FW and allow me to login to the Internal Memory to access my files.
Does anyone know if using "Repair or Change File System" will impact the Internal Storage?
Try to reinstall the Stock Firmware Through Odin, I had this problem also when I used to own a J5... All I did was just Reinstall the stock firmware... if you want to find the stock firmware.. just go to sammobile.com

Bricked after random reboot Issue with /data partition

This time phone don't wont to start - in TWRP log I have information:

Encryption issue : can't mount partition Android 10 - no passwird

Hello guys,
I have an issue regarding this Havoc ROM under Android 10. When I fash it and reboot it, it encrypt my /data, and recovery ask me for an unknow password.
I have already test to set up a PIN code into parameter in adroid but it's doesn't work.
I have tried to change the data partition ext4 -> ext2 -> ext4 nothing has changed.
Because I can't mount /data partition I can't wipe dalvik and cache, so I can't get last updates ....
I have used twp and orange fox recovery, they both make same issues.
