[Q] Need urgent help, can't mount cache - G2 Q&A, Help & Troubleshooting

Hi guys
I really need help with my G2.
Basically, I installed resurrection remix, everything working fine for a week.
Today, when i used my phone, it kept force restarting. Finally, it got into a LG logo bootloop and has not been able to start up.
I managed to get into TWRP recovery but when I tried to reflash my ROM it said it could not mount system.
I decided to flash CWM to see if I could fix the problem and sure enough, it fixed but there is another problem.
When i tried to wipe cache, it hangs and freezes and gets stuck on formatting cache.
I reboot and I see these messages below:
E: Can't mount /sdcard/
E: Can't mount /cache/recovery/command
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
I decide to try wiping cache again but to no avail.
can anybody help me?
Thanks in advance

[Q] Nexus 7 (2012) Shutting Down for no reason

Ok.... A brief description....
Nexus 7 is on..... Sometimes it's in the dock..... Sometimes it's in the case.....
All seems fine and running.....
Then.... When not in use (in the case) or sometimes charging in the dock, It just shuts down and will only restart with a loooong press on hold of the power button. In all cases, the battery is 90% > 100% charged.
Now.... I have reset the cache and factory reset a few times.... Yet the problem is still there.
Last few times, I have reset the cache and then the factory reset.... The reset of cache works fine, but if I reset the cache prior to factory reset, the factory reset shows a bunch of errors trying to access the cache....
Am I doing something incorrectly or does it have to go back to Asus for a second time?
These issues didn't start occurring until after the last system update to 4.4.2

How are you resetting the cache? Do you mean clearing the cache? Are you referring to Dalvik cache? Are you doing this via a Custom Recovery (CWM or TWRP)?
What error messages do you see? Can you post a screenshot of these error messages?
Sorry for the barrage of questions... but the more information you can provide, the more likely you are to acquire a diagnosis, and a possible solution.

I am clearing the Dalvik cache..... This is done in stock recovery on an unrooted Nexus 7.
I can't take a screen shot unless I do a full factory reset again... But if I remember right it was trying to access E drive and the at least on error said it could access the cache...

Hi, Legobricke...
Apologies for not getting back to you sooner, but I've been really busy this past week with work.
And if truth be told, I've also been finding excuses not to write this post... because I hate delivering bad news. And your above quoted output, I think, is very 'bad news'.
Everything about it suggests you have either a bad eMMC/NAND chip (hardware failure)... or a partition corruption.
There is very slim possibility you **might** get your Nexus 7 working again, by fastboot flashing a Google factory stock image... but given your previous descriptions of random shutdowns, and this sort of thing...
Code:
E: Failed closing /dev/block/platform/sdhci-tega.3/by-name/MSC (I/O error)
(...and which is something I've never seen or heard of before...)
Well... I'm not optimistic fastboot flashing anything will work, to be honest.
I think your best bet, is to return it back to Asus and hope they'll fix it.
Sorry I couldn't be of more help.
Rgrds,
Ged.

Boot Loop Nexus 4 - dead eMMC?

Recently, my Nexus 4 has been crashing randomly - shutting off with no warning or notice. It has always rebooted back up without issues. Last night, however, it just got stuck in a boot loop - spinning balls for hours on end.
Bootloader and Recovery Mode come up with no trouble.
The phone is and always has been pure OEM/stock. I've only ever updated using built in OTA process.
I tried to reflash to stock using Wug's Nexus Toolkit, but it repeatedly failed saying the device was locked. I tried to unlock the bootloader, but that seems to require a reboot to take hold, and every time I tried the reboot it would loop again.
In Recovery Mode, I get the following:
E:failed to mount /cache (Invalid argument)
E: Can't mount /cache/recovery/log
E:failed to mount /cache (Invalid argiument)
E:Can't mount /cache/recovery/last_log
E:can t open /cache/recovery/last_log
E:can t mount /cache/recovery/last_install
E:can t open /cache/recovery/last_install​
I have downloaded the full image and tried flashing the cache, and system with no effect. Toolkit doesn't show an error, but nothing changes.
Does anyone have any suggestions? I'm at a loss.
Did you try
fastboot erase cache.img
fastboot flash cache cache.img
Then perform wipe data/factory reset before booting into android.

Error can't mount cache

Hello.
I have a Nexus 7 and doesn't work. The battery gone out and when I turn it on it hangs a screen with Google logo.

Do you know what can I do? I don't mind if I have to delete everything, I just want the tablet works again.
Thank you very much.
