SOLUTION For Can't Mount /Data Or /System Or /Cache - Lenovo A6000/Plus Guides, News, & Discussion

I Got a solution for a error in TWRP which is Unable to Mount Data or system or cache or storages. this error causes trouble while flashing the custom Rom. I also suffered from this trouble and finally i got a solution of this. i am not sure this is going to help you but i am sure that it helped me. Try at own risk.
1) Go to the twrp recovery.
2) Go to Wipe section then go to advance wipe section then select the partition in which you are getting trouble. eg. i was having error of cant mount system so i select the system.
3) After selecting DON'T SWIPE TO WIPE instead of that go to repair or change file system.
4) In that select the change file system and from the next screen select the EXT4 and then do the swipe on the next screen.
5) after that do the repair of that particular section. you can find the repair in the Repair or change File system.
6) now just wipe the system as we do normally. and bingo you solved the error.
This trick worked for me some how i am not responsible for bricked phones or any other damage. But if this helped you please press the thanks..!!! :good:

Soft bricked Galaxy Player 5.0.

Hi guys,
As the title said, Galaxy Player 5.0 Wifi got soft-bricked during the flash process. Now, it stucks at the loading screen with the samsung text only. I can still get to the Recevery and Downloading mode but up till now I have tried flash many stock ROM, factory reset without hope. I believe that it's the software conflicting problem or problem with the bootloader
Please help me with this, my friend ask me to flash it to Cyanogen Mod 9 and I bricked his player. That's really bad for both of us. Before any thingies, it run on Froyo and on the back cover, it said YP-G70CW/ Made in CHina
Please help me with this soon ( any suggestion is appreciated
Hello my friend!I will say again:
ALWAYS WHATEVER IS HAPPENING,BEFORE FLASHING A NEW ROM YOU MUST BACKUP THE CURRENT SYSTEM FROM CWM!!!
If you have this,you may go to back-up and restore in CWM,restore and vouala you have again your current rom.
If you have not made a system Back-Up (also Nandroid backup) you will have to download a new rom,send it to your device in downloading mode and then install this.
I can suggest you the ROM CM9 that I use because its just awesome.Just a little prob with the preloaded microSD card.
What device do you have?INTL or USA?
Actually, I'm having the .zip file of CM9 from this topic as well : http://forum.xda-developers.com/showthread.php?t=1679957
However, even though I can connect my phone to the computer, use ODIN to root it and flash the .zip file after factory reset, etc. , the situation is still the same :-< It stay stuck at the samsung logo like forever
I believe I'm using an Intl one because it has hot physical home button. However, the back cover read: YP-G70CW Made in China. Therefore, I don't know which ROM should I flash??
do you follow ALL the instructions from this thread?

I did. I did the factory reset and deleted cache, etc. before installing the .zip file. :-<
did you do this in CMR:
Wipe data/factory reset
wipe cache and wipe dalvik cache
?
To wipe dalvic cache go to advanced section in CWM

yes, i meant CWM, mistyped it..
I did them all too. However, for the Dalivik cache, it does not show up text at all, just a little flash nothing changes. What seems to be wrong here is that every time I finish an action, it show up 4 line of errors like: can't mount to cache/..../recovery.log. Is that the problem??
Yes thats the problem.You may have locked the internal SD...Try formatting you external SD and then pass your zip again,this may fix the problem
If system can't mount it's files,there is no way it will load.
I took the external SD card out, formatted it and flashed the CM9 again. No luck
The four lines of error read like below, they keep appearing every time I do something:
E:Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log

Those errors are common within using CWM for the Galaxy Player 5. If you rebooted the device, it will most likely go away. There is no need for concern.

[Q] flashing cfw on sd with cwm the same steps or different?

hi i have used mindcr 2.9 rom i like it but wanted ro try different rom. well i have flashed mindcr many times cause i deleted something i need. so i toght i should try ankther rom in this case i chose simplicity v4 . but i cold not go into download mode only recovery so i wanted to flash back stock rom but i coldnt tried everything epcept the usb jig .. anyways i sent it to repair.. ill be getting it tomorrow. it was working only thing download mode did not work i tried all methods no luck . so here is my question... can you install another rom over mindcr with cwm? i search and many people said yes. so i did an phone got hard brick. if it dont matter then the procedure that i followes was wronf. are all roms installed trhu cwm in sd ca rd always the same dprocedure??? if so should i used the mindcr that i been using. any link for simplicity v4 ultimate i dont want v5 procedure from mind ans simplicity were almost the same are roms always installed the same procedure? i think if u can install a rom over anoher rom installed procedure from place i followed bricked my phone... thanks
It is best to install a Rom over stock. Even flashing over a Rom works sometimes. And yes every Rom is installed through cwm or e3 recovery. Simplicity v4 should be flashed the same way as mindcr Rom.

When you go into CWM recovery, there should be a section called Backup/Restore. Back up here, it Will take about 150mb-350mb of your sd card depending on what you have. So if flashing your Rom goes wrong you can go back to CWM and restore.
Then follow the procedure which is
- Root
- CWM
- Mount everything (it should look like unmount/system, unmount/data etc)
- wipe data and cache
- Advanced » wipe dalvik cache
- Mount everything again
- Install .zip from sd. Find the Rom and flash it.
This procedure will definitely work. If it doesn't just restore and try again.
Also, don't say thanks, but press it if I helped you

Help with a total wipe for new ROM install.

Hey everyone, I am looking for a little clarification on something. I have a Canadian Rogers i717r. I am running the stock Rogers Jellybean ROM I717RUXMD1_I717RRWCMD1_RWC, with root. Recently, I have been noticing some issues with it hanging, and doing other odd things, so I just think it is time for a reinstall. I may have installed a bad app or something along the way, because it does happen from time to time. My main question is this: How do I do a complete system wipe? Now I am talking every old file, so there are no remnants of the old information left. I have done the factory wipe and dalvik wipe, along with the cache wipe, prior to installing a ROM, every time I have done a new ROM install.. It always seems to leave files behind though. Old game files will still be there and such. Is there a way to get rid of it all, so it is a complete clean slate for the install?
Now, I use TWRP, but the idea is generally the same when it comes to this procedure, and I have found these instructions online;
-- The correct procedure for doing a full wipe is below.
Go to clockworkmod recovery.
Volume up, power button, and home button all pressed together for a couple of seconds.
Go to Advanced menu and wipe the dalvik cache and batt stats if present!
Go to mounts and storage and select it.
Go to format / system and select it.
Scroll down to format system and select yes.
Go to format / data and select it
Scroll down to format data and select yes.
Go to format / cache and select it.
Scroll down to format cache and select yes.
Now go back and install the rom from the internal or external sd card.
This is the correct way of doing a full wipe everything is erased and formatted ready for the new rom, no old system files, old kernel remnants etc....
I am curious as to what will have to be done after the install is complete. I am going to lose ALL of the info. I would basically need to redo all the programming on the phone, including the IMEI and all the info for the networks and what the phone needs to recognize what network it is allowed to access and such. Is this what it will boil down to? I will basically need to reprogram the behind the scenes info also, or no?
Thanks in advance!

First, If you're currently using TWRP I'd suggest updating to the latest version, if you haven't already. There's a few of the newer ROMS which specifically require it. On the question of wiping, before you get too carried away it might help you to backup a few things. Within TWRP (ver 2.8.1.0) you have the options to backup EFS (anywhere you please, Internal storage, internal SDcard or MicroSD card) by clicking on the Storage: bar just above the swipe icon. Your IMEI >> located within EFS folder. Also, search the TWRP website for more specific instructions. What you posted is CW instructions. Hope it helps!

Data Partition corrupted??

I have an S3 (i9300), and in recovery (TWRP 2.8.6.1) It will give me errors that it can't open folders in the data partition, so Aroma installer roms cannot format data, and I get a long error every time i data reset.
Data/misc/audit is unopenable (can't see it in file explorer in system, but i can see the folder in recovery)
Data/data/com.samsung.dcm - a folder in there is unopenable, is named as a tilted square with a "?"in ES.

For anyone still with this problem, the solution is to reformat and repair any faulty partitions in the advanced wipe menu in TWRP.
I am having this problem with an S3 that I'm trying to restore to stock. I can get TWRP on the phone but no image will install nor saved backups will restore. The reason is the data partition is corrupt. When I try using the Advanced Wipe option to repair the partition it reports:
/sbin/e2fsck -fp /dev/block/mmcblk0p15 process ended with ERROR: 4
Unable to repair Data.

Any other thoughts on how to repair the data partition? It was just working before trying to restore to stock, so I doubt it is a hardware problem.
For those facing the same problem. I did fix this but I can't tell you exactly what did it. I used the Terminal in TWRP to repair the partition manually. I think I used "e2fsck -cvf /dev/block/mmcblk0p15" and accepted all repairs. Be sure to say "no" to the first question that recommends you to stop. Then I used TWRP to format the partition and then it mounted just fine. I did many repairs on the partition using e2fsck and not all of them worked so I'm not 100% positive I know which options did it. I think it was "-cvf" but maybe "-B" also played a role. Either way, you gotta get that partition repaired before it will format and then mount.
Maybe flashing a stock ROM, with or without a pit file, would also work?

I tried that. That's what led to my /data partition being corrupted. I tried Kies 2.0 and stock ROMs with Odin. I couldn't get beyond the corrupt file system. I even got to the point where download mode was complaining to me about things being jacked. I thought I bricked the thing for a while.
Did you try flashing a stock ROM with Odin? Kies can't be used to flash a stock ROM unless you use the emergency recovery option.

CM13.0/TWRP - Unable to unmount system in recovery

Hi,
I have an unlocked bootloader on the XT1521, with TWRP and Cyanogenmod 13.0 installed. I just updated CM via OTG, which worked correctly, but all Google Apps were removed. When I tried to flash them afterwards, nothing happened.
So I went on and wanted to wipe /system to reinstall CM and GAppsbut apparently, my /system partition is "busy" and cannot be unmounted. I get this error all the time, regardless if I try to a) uncheck the "mount system partition read-only" and swipe to allow modifications, b) try to unmount it manually via the mount menu, c) try to wipe it (the "repair" option is not available for \system unlike for /data, e.g.), d) try to flash CM13.0 zip. The error message is always like "failed to unmount '/system' (Device or resource busy)" and, oddly, I did not find any similar issue via Google, as it is not just a "read-only"-related problem.
Does anybody have a solution to that issue? Thanks!

Hey i had this issue and finally pinned it down to the TWRP I was using. It turns Official TWRP has this issue. This can easily be resolved if u flash Squid's TWRP
Download the latest version from here:
http://forum.xda-developers.com/devdb/project/?id=10398#downloads
That was the problem apparently. Thank you!
Thank you! I was having this problem as well and that fixed it.
Thanks very much for your help!!!
I was scared of loosing my phone...
Thanks.
I have a US Cellular XT1526 and was unable to install GApps on CM13 without this. CM13 installed fine, and GApps looked like it installed, but on reboot nothing was there; GApps failed to install. Using Squid's TWRP fixed it; thanks!
