Hi there,
Today morning I notice that my Nexus 6 switched off with no reason, no root or anything else, I tried to turn it on but it stuck on google logo, after that I decided to reset to factory from recovery using Wipe data/ factory reset, I surprised that I received these messages:
Formatting / data ...
E:failed to mount /cache (Invalid argument)

E:Can't open /cache/recovery/last_install
E:Failed closing /dev/block/platform/msm_sdcc.1/by-name/misc
(I/O Error)
E:failed to mount /cache (Invalid argument)
What can I do now ? I just put my mobile on charging at night and went to sleep
Thank you in advance.
This appears to be a common issue that has vexed Nexus 7 owners in the past. The problem is related to corruption from an update. The usual fix would be to flash a factory image, but to do that you would have to unlock the bootloader. I doubt you did. Fortunately, there still is a solution that may help: sideloading the Android N Preview 1 OTA zip Google provided some months back. It's a complete system image, and installing it should get your device running. Afterward, you can unlock the bootloader (recommended) and flash the latest factory image from Google. If unlocking the bootloader is something you don't wish to do, subscribing to then unsubscribing from the Android N Preview program should push an Android 6.0.1 factory image to your device.
Back up your pictures and documents on internal storage before doing this or else they will be lost.

Thank you for your reply, i don't care about the data in my phone I will go with Android N.
If you have a link it may help I will be appreciated.
Thank you,
Check the General subforum. There should be an entire thread about the Android N Preview there, including how to install it.

Sorry if this is a re post but I have stayed up late and have not found a answer to my problem. Or at least a way that I havent tried.
My problem is that I am stuck on the ATT white screen. I can get in download mode and recovery but cant seem to get past that. In recovery it states
Media files copy failed.

Any help would be great minus the Noob Bashing please lol
Ok never mind now I finally got it with a combination of 2 things. One using I897UCJF6-final-OCD-REV0.zip from http://forum.xda-developers.com/showthread.php?t=731989 to rewrite the everything back, but it made it boot loop, so i used One Click Unbrick and all my problems went away.
My phone when rebooting will not get past the galaxy S start up screen.
I tried to install Team hacksungs ICS for samsung Galaxy S i9000.
I went through all the steps as correctly as I thought but when it restarted for the final time it would get into ICS and present a message and ask me to restart, so I did and it would get stuck changing between the regular boot and cyanogen mod.
To fix this I thought it would be best to re flash it back to a ginger bread stock. which I did and that worked, I tried the process again in the hopes that it was something random but to no prevail.
Upon going into download mode i thought i'll just go flash back to the rooted version of my phone
But when I rebooted after that it would not get past the start up screen
I've even flashed it with the custom rom and with the stock gingerbread but they both start up the same and won't get past he start up screen.
Oddly if I use the custom rom which has clockwork recovery pre installed the reboot menu screen will that instead of the regular one.
I would take a picture but my phone is my only access to a camera
Here's what i'm looking at on the reboot menu: (hope it helps)

It doesn't matter. You had a thread open and were getting help in it. You don't just open a new thread because the first advice didn't help.
And ... you did do it wrong, go back, read, search and follow the basics.
I don't know much when it comes to this stuff but my phone was acting up and i went into recovery and went to wipe cache partation. When i did that the wipe cache failed. i rebooted my phone and its been on the boot animation the 4 little dots floating around for the last 30 mins.
and this shows up for the log

I'm not sure what to do or how to fix this but i do know there is a way to do it on here.
either reflash your rom, or restore your backup..
if anything just go back to stock
it took really long about an hour but doing a factory reset and let it sit there for an hour fixed it.

Hello
I have a problem.
The smartphone is constantly loaded into the eRecovery
When downloading the TWRP, it is displayed in red:
Failed to mount /data (invalid argument)
Unable to recreate /data/media folder
Failed to mount /cust (invalid argument)
Failed to mount /data (invalid argument)
Failed to mount /system (invalid argument)
TWRP does not see the memory of the smartphone and does not see a memory card.
How to fix this problem?
I don't know what are you going to do but try to do a factory reset using twrp
Go to Huawei website and download firmware M.M
install stock recovery if you install TWRP
Move file update to sd card and move to dload
After that install use 3 Buttons
