All of sudden E: Unable to mount '/cache' - One (M8) Q&A, Help & Troubleshooting

This never happened before. I wiped cache and dalvik cache before I flashed the HK sound mod, it was fine, I then installed the Viper4android installer, the screen was frozen on "please wait" for a long time, I pressed and swiped the screen a few times and it suddenly showed E: Unable to mount '/cache'. I then tried to wipe cache/dalvik cache again but a few more red lines similar to the E: Unable to mount '/cache' showed up. I then pressed reboot.
The thing is my phone seems working fine and both HK sound mod and V4A work but I don't dare to wipe anything in recovery at the moment.
Can someone let me know what happened? Is my phone okay or not?

Flash stock recovery and FORMAT cache partition. After this you can return to TWRP.

Thanks it seems okay now.

[Q] my HOX gone crazy

Hey guys,
I'm getting really frustrated with my HOX. I'm desperate for help.
I kept getting these gapps, android.acore and htc.bgp errors which caused all the apps to crash also suffered from random restarts with JB and I rollback to ICS 4.0.3. Still no good. Same stuff happening.
I did so many cache wiping, factory resets resotring my system but nothing seems to get my device to work properly for more than two days.
Sometimes i got these errors right aftor a recovery, so its not because of a specific app.
Today my phone just shut down and refused to start (HTC white screen stuck).
I tried restoring my old system image but clockworkmod gave me "Error while restoring /system!" with I/O errors.
I don't think there is anything wrong with OS but something more native not ruling out hardware\battery issues.
Any assistance would be more than helpful, i'm really struggling here ..
I don't get any replies so i'll try to explain myself better :
My HOX gets a lot of gapps/htc/android errors. Factory reset and recovery doesn't solve it.
Every two days my device is shutting itself down and won't start until I do a full recovery of the system (which sometimes fail).
Happened with JB and now with ICS stock rom.
I just downloaded a 3.14.709 backup, flashed it using clockworkmod and the first thing to appear was an android.acore error and the phone shut down.
I think there is something wrong with the hardware or serious software issue I don't understand.
Is there away to completely wipe the whole device and install everything from scratch ?
Any thoughts would be greatly appreciated ..
Do a Factory Reset in recovery and go to "mounts and storage" and format system too.
Then Wipe Cache and Dalvik Cache to be sure
Now flash the rom you want + kernel from fastboot (fastboot flash boot boot.img)
If tyou still have such problems then its most likely the hardware...

Thanks a lot for the advice,
I did the following :
1. Factory reset - wipe cache \ data \ sd-card
2. Format system
3. dalvik cache and cache erase
4. download a recovery for my cid from the forum here
5. flashed boot.img
6. restored the recovery using clockworkmod
7. flashed gapps.
The device went up ok but I hope it lasts more than a day or two before it start rebooting \ crashing.
The last time I did it it gave me errors before it even showed the home screen.
Once again thanks a lot .. I will post further updates soon.
Good luck,buddy.
Tough luck,
After less than 24 hours I started getting Talk\Facebook\Play\Whatsapp has stopped.
Than the phone got into a boot loop and wouldn't start (Stuck on HTC white logo screen).
When I went into boot recovery and try to wipe the phone to load a recovery I got these errors :
E: can't mount /cache/recovery/log
E: can't open /cache/recovery/log
and
E: format_volume: make_extf4fs failed on /dev/block/mmcblk0p12
E: format_volume: make_extf4fs failed on /dev/block/mmcblk0p13
E: format_volume: make_extf4fs failed on /dev/block/mmcblk0p15
Error formatting /data!
Error formatting /sdcard!
Error formatting /system!
etc .. etc ..
And it wouldn't let me choose a backup to restore.
I'm getting more and more convinced it's not a rom\boot\kernel issue but rather a hardware issue ..
Any thoughts on my assumption or fresh ideas ?

Can boot only into CWM on Tmobile SGH T-989

I loaded CWM v5.0.2.6 then wiped cached and dalvik cache then did a master reset. After rebooted, goes into bootloop with the tmobile s2 logo, progress bar goes all the way to the right then reboots, sometimes to the middle,sticks, then reboots and repeats. I then updated the CWM to v6.0.4.3 this morning, updated fine but told me my phone was not rooted. When I try to wipe cache, it hangs on the formatting cache (don't know if this latest CWM is compatible with the t-989?) If I try to do a reset, the recovery hangs. I have had this S2 since the S2's first came out with Tmobile.
I want to install a fast kicka** rom. Well, as fast as an S2 is concerned. Just need help. Trying to learn the OS also, but for now just want to get this running. Thanks.
1.Phone is not rooted, (correction, I just ran a rooted program while in recovery and it passed,so maybe it is) I thought is was but CWM recovery said it wasn't
2. Boot loops while loading with Tmobile S2 logo displayed
3. Loaded CWM rocovery v5.0.2.6 When a master reset/wipe was performed with this version, it completed but still boot looped
4. Loaded CWM recovery v6.0.4.3 When trying to do a master reset/wipe cache, hangs and freezes. Will complete a Dalvik wipe though.
5. This 989 has been unlocked also from Tmobile

I put Carbon ROM on my phone last night, well, I tried. I put the file on an SD card, installed the card and powered up into CWM. Performed the install, everything went well as far as the output from the install went but now, as expected, do not have the T-Mobile S2 boot screen with progress bar, just a blank screen after I reboot, get the samsung logo, then it looks like something tries to start in the middle of the screen then freezes.
I can go back into CWM no problem, perform a backup, reinstall Carbon ROM, everything in CWM works, runs fine EXCEPT when reading erasing or wiping the CACHE.
And I always get the:
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
I have a feeling it is something with a corrupted file in the cache; wonder how I came to that deduction?
I will keep posting till this is resolved, am scouring the internet for solutions and answers to screen printouts while going through the steps
to resolve this.

Note 2 sudden problem

This happened a few days ago. So first of all what happened was before I went to sleep my phone rebooted by itself for no reason which I thought that maybe my phone died,But the next morning i woke up to a samsung logo on my phone (not blinking) which I thought was rebooting again, but it wasnt booting into the OS. Im running dirty unicorn 4.4.4 (final ver) and the unicorn booting animation wasnt showing up. Before I try to boot/go into recovery/bootloader there is a red blink ( not too sure if that was always there) and I am able to access my recovery and bootloader. I checked my recovery log and it says the following:
E:unable to find partition size for '/boot' '/recovery' '/modem'
E:unable to mount '/efs' '/cache' '/system' '/data' storage /data/media during GUI startup
E:Failed to get default contexts and file mode for storage files
So seeing this I tried going into my bootloader which I was successfully able to go. Therefore I tried flashing stock through odin and resulted in failing or just freezing. *Had notes about being unable to write
I had this phone for 2 years without any problems and I'm with Rogers. Has anyone else gone through this or know a solution?
A similar thing happened to me recently. The battery was part of the problem I believe (for 2 of my Note 2s), as it wasn't holding a charge properly (this was causing problems from charging, to regular freezes, reboots). Finally, the last time the phone just got stuck on the samsung boot logo. By then, I had my new battery, so I swapped that in - but that didn't fix the problem. I booted into Philz recovery and saw the same error messages as you. I wiped dalvik cache 3 times, factory reset, and reset for installation of new rom (which still gave me the same error messages and something about unable to format E. Despite the error message, I proceeded to reinstall the custom Rom (Ditto Note 3) again from an external SD card. Everything loaded up like normal. SMS, chat records, contacts were all in tact (like a dirty flash). That said my wifi was having issues - so I ended up redoing the aforementioned process (clear cache, factory reset, reset for installation of new rom). This time no messages about the E: location. Installation was fresh and all content was wiped clean. The wifi issue was still occurring - but it turned out I just needed to install the AGNI kernal again.
Good luck

So did you install it using an external sdcard?

Need help can't wipe device with twrp or cwm error E: Can't mount '/Preload'

I was trying to flash a new ROM so i tried to wipe data and cache and delvik cache but each time i try to wipe the phone i says E:Can't mount '/preload'
but i didn't notice the error and installed custom ROM anyway.and now i am stuck at boot screen.
i can still access TWRP manager and download mode but still can't mount '/preload'. I have searched a lot online but no satisfactory thread found.
Detailed help on this topic will be much appreciated.:good:
thanks
I am not sure what would cause the error but the simplest solution may be to flash back to stock, flash TWRP, and re-flash the custom ROM.

no cache partition error?

I am getting a lot of little issues with this device. Its new, had it for a day now, was able to get lineageos on it and everything seemed fine. Then during a reboot, it stuck on the sony boot screen, no way to power off, no reboot. Had to wait till the battery died. then it booted, with lots of bugs. Went to twrp and factory reset, and cache cleared. Except now I get an error of
"Unable to find partition for path '/cache' "
Any idea how to fix? I can not wipe it, etc.
