Hello, I faced unique problem. Device Nexus 5 D820. I've read a lot of topics on how to flash stock dactory image, clean, and did everything the same as described there.
Problem is that I am not able to flash lollipop (Android 5+) factory images. I mean everything goes fine, but when it comes to final start of the system it stucks on flying dots (dots are moving) over 12-24 hours and won't open. However the KitKat (Android 4+) factory images flashes properly, the system loads in 10 minutes. I also tried to update from Android 4.4.4 by google update (Android 5+) notification, but it also gets stuck on the same flying dots. The problem began when my device running Android 5.1 several months suddenly rebooted and system asked me to enter password (I do not use any passwords on phone), I entered my google account password, then it stated that the data was corrupted and needed factory reset. In order to avoid this I just turned it off and on and it stucked in flying dots. When I tried to wipe cache first the following errors appeared:
E:failed to mount /cache (Invalid argument)
E:can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (Invalid argument)
Then, after several flash things these errors do not appear already, but problem still remains. I already delete all data, so no need to bother keeping data. Any Ideas what causes this problem?
When I boot from TWRP and do operations the following string appears during operations (wipe cache, etc.):
Updating partition details...
E: Unable to mount '/persist'
I had a similar problem.
Make sure you wipe dalvik and cache in recovery before rebooting.
Finally, nothing worked until I did a factory reset after flashing.
Be sure to first backup photos, documents, etc. in addition to nandroid and titanium backup.
Update: problem SOLVED

Hi, looking arround here for 4 weeks now, cant find help....
Flashed the 3.4.3_11-Stock.UKTmobile_BLUR (my mistake, wasnt fixed...)
since that Market cant download apps, and defy recovery says:
E:Can´t mount /dev/block/mmcblk1p24
(invalid argument)
E:Can´t mount /CACHE:recovery/log
E:Can´t open /CACHE:recovery/log
tried to wipe data, wipe cache etc...
Restore Factory Settings isnt working either
Restore in Recovery isnt working, only a MD5 error occures
was able to flash 3.4.2_164-Stock.Orange_BLUR.sbf.
still same problems....
what can i do??
I was able to fix it by restoring 3.4.2-155 nandroid, after it flashing 3.4.2-155 fixed sbf, and then after boot i entered default recovery and wiped data.
After it market started working
If edition tip don't solve your problem, try to format de SD card.
any hope to fix this ... i have the same problem
no change..
sorry, applied rom and fix, no change...
All I can do now is wait for Motorola to bring up the 2.2 rom in Germany, flash it, and hope for the best.
I had this problem 2 nights ago, solved in 2-3 hours searching the net.
1 - kill all google apps in memory
2 - use a tool to clean the cache
3 - umount your sd card, format, then reboot in recovery (don't mount de card again)
4 - clear dalvik cache (in advanced) and cache, then reboot.
If problem persist, do all again and restore permissions in recovery (advanced)
well, i had this problem too when i messed up with some sbf(s).
then now i'm using S.Froyo CEE edi. i wiped and restore nandroid. now everything is working. voila!
I've managed to get that awful Rom (Destroyer) Manager off of my TF101G and have got Rogue on via PERI and now I'm trying to flash the stock ASUS ICS Rom but can't delete the Dalvik Cache because I'm unable to mount /data
Code:
- - Wiping all user data - -
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure
Cache wipe complete.
Formatting /cache...
Cache wipe complete.
Wiping dalvik-cache...
Error mounting /data!
I'm assuming that /data is stuck on read only?
Manually fixing permissions and then mounting /data also shows the same error.
HELP :crying:
I have the same problem. I know what lead me to it.
Its an Asus SL101
I have cyanogenmod correctly installed. In order to install a megatron rom I downloaded their app called megatron apps. Trying to download a rom from them I got validation error at end of download and I make the stupidity of change the download dir from /mnt/sdcard to /sdcard and then when I restart again it doesn´t load and CWM recovery give me the same errors (unable to mount /data or unable to mount /sdcard when cleaning cache or trying to restore a backup ).
The only thing I have been able to do its to install Rogue XM Recovery 1.5.0 instead of CWM 6.x ) but the problem to apply an update or restore a backup persists.
Any idea ?
Aaargh.
After a year and a half of heavy CWM and TWRP usage, this has suddenly happened to me too, possibly after flashing the updated TWRP blob from Goo Manager (although that's conjecture at best). My ROM (RaymanFX' CM10 v6) is fine in everyday use - no problems whatsoever, but now I want to update, and my recovery won't let me.
In the hope that something simply went wrong during recovery blob flash, I successfully deleted TWRP and flashed a different recovery (latest CWM) from ROM Manager, but the new recovery can't mount anything either - neither sd card, data, or cache. The error messages are more or less identical to TWRP's errors. My system MAY be readable, but I can't backup or restore or flash anything anyway, so I don't dare format it.
I don't have a Windows PC, so I haven't tried Easy Flasher. I could try it on my work computer if there's no way around it and if neither OSX or Ubuntu can help.
Any suggestions?
at first im just failing at wiping cache.
now i cant even restore my TWRP backup.
it is saying "Failed to unmount '/cache' (Device or resource busy)
now my phone got no OS :crying::crying::crying:
I was facing the same problem.recovery twrp>wipe>advance wipe and then select system>repare or change size>change file system>select FAT
after doing it try to restore your backup and if you get error the only way flash your phone to the last build number(avalaible for your phone) and then install twrp recovery(last version).
restoring backup should be work with this method.
you can try this method
Mount>select partitions to mount : cache
select cache and after doing it go for restoring.

No need to restore /cache partition, exclude it The partition is used by TWRP that's why you can't unmount it.
I still have the same problem persisted. Can't wipe cache with this TWRP recovery. It says can't mount/unmont cache device or resource busy. Restore of the backup was impossible as well. Even when cache was excluded. Changing file types and repairing it also didn' work. In Mount cache is ticked permanently and it can't be unticked.

Hello everyone, thanks for the help in advance
When trying to do a factory reset on my phone, the computer restarted and it seems that my recovery was deleted
I installed the TWRP by fastboot, until there everything ok
when deleting the data, it gave an error "Failed to Mount" / preload "(Invalid argument)
and since there everything went wrong,
I tried reinstalling the rom, and it doesn't work
I tried to reinstall the backup I had and neither
always the same error when doing wipe "Failed to Mount" / preload "(Invalid argument)
I tried to change the partition format according to what I read and I can't solve it
Any suggestions? Thanks for your time
hey, something similar happened to me and I am already very frustrated, I had done the whole process of installing the havoc os ROM and everything was going well, until when installing the MagisK from TWRP, it remained on the loading screen (a white circle and It started again and it did not start), I went back to TWRP and reinstalled the backup but when the process is going to finish the following appears: "failed to mount '/ product' (structure needs cleaning), it does not allow me to swipe, install, literally nothing process because it tells me that at the end. I need help, I already fixed the mount system but I haven't found anything for this ...
Did you backup that partition too?
Nvm I just remembered.
The /product partition in Android 9 is an extension of the /system partition
Try format it then mount it again then restore the backup.

I lost the backup and it does not allow me to carry out any process literally, in the end it throws me that error, the only thing I did was format from the pc, reinstall another version of HavocOs and it came out the same, but I connected it to my pc and it showed me the Havoc battery charging animation, but fails to get past samsung home screen, again ...
