I'm going to start off by saying I'm the noobiest of noobs, so please be gentle with your replies.
I was watching Youtube on my Nexus 5 yesterday when it suddenly shut down and attempted to restart itself. I watched it go very slowly from the white Google logo to the colourful spinning balls screen, and it got stuck there.
Status right now:
Phone stuck at spinning balls screen
I can get to fastboot and factory recovery screen
Factory reset doesn't work
Power button appears to be working fine
Charging is fine and I can see the battery icon when it's off
Phone is not rooted, bootloader has not been unlocked
What I did so far:
Someone posted a thread with a similar problem and said to flash the factory image a few times, so I followed these instructions. Except to do that I need to unlock my (currently locked) bootloader first. I then tried to follow these instructions of unlocking bootloader, but got stuck at the last step of "fastboot reboot“ because my phone still won't get past the screen of spinning balls, no unlocking the bootloader for me. HELP!
This is what's at the bottom of the system recovery screen:
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)
E: Can't mount /cache/recovery/last_log

So. Have you tried the fastboot commands to fastboot flash system system.img and boot and cache etc etc?

I think I have, it didn't work because the bootloader is locked, and if I am able to unlock it right now, there would be no problem.

Not surprising. We already know your phone won't boot and that what that command tries to do. Use the command "fastboot reboot-bootloader".

Not a good sign. Points to a physical problem, not software.
And you have done fastboot oem unlock yea?

Yes, the status shows as unlocked right after I do fastboot oem unlock, but as soon as I reboot it, goes back to locked again.

USB Debugging has absolutely nothing to do with fastboot in bootloader or ADB while in recovery.
It is ONLY used with ADB while booted into Android. NOTHING else.
Flash factory images using fastboot while in bootloader or reflash your ROM in recovery.

Hi!
I updated my moto g when the official OTA 5.0.2 arrived, It worked properly more or less, for some days. It began to fail some apps and suddenly to black screen. When I push the power button only appears the logo of Motorola.
I can enter in fastboot mode and recovery mode, but when I tried to flash a stock ROM or anything like a custom recovery It does not work. (with mfastboot).
In fastboot mode appears this:
writing logo
(bootloader) Failed to erase partition
(bootloader) Failed to flash partition logo
FAILED (remote failure)
And in recovery mode appears this:
E: Can´t mount /cache/recovery/last_log
E: Can´t open /cache/recovery/last_log
E: Can´t mount /cache/recovery/log
E: Can´t open /cache/recovery/log
E: Can´t mount /cache/recovery/last_install
E: Can´t open /cache/recovery/last_install
E: FAiled closing /dev/block/platform/ms_sdcc.1/by-name/misc
(I/O error)
The moto g is a XT1032.
The bootloader version is 41.18
Can anyone help me?

I tried with this one and did not allowed to install it.
From TWRP web > openrecovery-twrp-2.8.5.0-xt1032.img
Is the same?
Try flashing Philz for the falcon from here: http://forum.xda-developers.com/showthread.php?t=2639583
I used Philz on my xt1032 because I was having problems with TWRP whereby it was giving me strange errors.
I have the same problem - any solution?
After the OTA update to a higher Android version (I believe it was Lollipop) I started to face WIFI / WLAN connection issues.
But now the XT1032 / Moto 1st gen totally died in the same way that you are describing.
"I/O error" tells me there is something fundamentally wrong.
Sames messages, and tried factory reset multiple times.
Additionally, after "Power down" the phone still seems to be alive, since the display flashes every 4 seconds briefly, showing the Android logo which is also shown in recovery mode.
And the battery is at 0% after a couple of hours - so the phone is still "on", even while powered off (officially).
-> Have you found a solution to your problem?
I have not dared to flash the phone with anything up to now in order to keep the warranty.
So I will send it to Motorola unless someone has a hint regarding a software solution...
Hi Motorino . i have moto g2 with exactly the same problem. Have tried everything......may also send it to motorola
How about fastboot flashing the 5.0.2 full factory firmware image: http://forum.xda-developers.com/moto-g/general/index-moto-g-falcon-factory-firmware-t3110795
@melbfc - Here is the forum for your Model: http://forum.xda-developers.com/moto-g-2014
Hello everyone,
Device Nexus 5(Android L 5.1.1)
my colleague was trying to unlock bootloader "fastboot oem unlock" and after that it stuck on erasing userdata for around 2 hours.
Then he restart device now while flashing it says "cannot mount /cache"and few other errors.
I tried flashing Stock 5.0/5.1 nothing works (Stuck at loading screen).
Then i tried Android 4.4.4 and it worded.
now at this point in recovery mode it still says "cannot mount /cache" and few other errors.
I cannot use gallery/camera/playstore.
When i opem gallery it says "No external Storage available".
So was he able to unlock the bootloader successfully? It's not very clear if he did

Sorry for the bad english.
Yes it shows unlock symbol below google logo. but the process was surely not completed. I think messing up in middle of erasing process caused this issue.
How are you flashing the factory images? I find fastboot flashing the images manually is the best way, each file individually and not with the flash-all.bat script.
You could try locking and then unlocking the bootloader again as well and see what happens.
I was charging my phone when I noticed it restarted itself and then now it's stuck on the Cyanogen Logo screen.
I've gone into Recovery, pressed wipe data/factory reset but nothing actually happens. A bunch of stuff shows up saying
E:failed to mount / cache (Invalid argument)
E:Can't mount / cache / recovery /last install
E: can't open /cache recovery/last install
I tried pressing wipe cache partition, same thing
I pressed wipe media, same thing.
Reboot to bootloader, it just stuck on Fastboot logo.
I havn't done anything to the phone such as rooting or unlocking bootloader. I just left the phone as it is and only did system updates provided by Cyanogen.
Any idea?

You probably have a corrupt persist partition. Download this:
https://drive.google.com/file/d/0B98G0KTJwnBFUnJCNldodGs2dE0/view?usp=docslist_api
You'll need to unlock your bootloader, which will wipe your device, but it's the only way. I have a guide here that explains how to unlock it (also how to install adb/fastboot and the drivers). Once you've unlocked your bootloader, put the persist file in your fastboot folder, open a command prompt from within your fastboot folder (shift + right click, then select open command prompt here), and issue these commands:
Code:
fastboot erase persist
fastboot flash persist persist.img
Once it's done flashing you can try rebooting your phone. If it still doesn't boot you'll have to go back to my guide and follow the instructions in section 8 to flash the stock images.
There's no way of saving my photos is there? I assume no...but might as well ask.
Thanks so much for the help!

Unfortunately not if you can't boot into the OS.
I typed: fastboot oem unlock
It says OKAY
So when I type: fastboot oem device-info
<bootloader> Device tampered:true
<bootloader> Device unocked: false
<bootloader> Charger screen enabled: false
I assume something went wrong?

Yeah, this happens sometimes. I can only suggest you try again in the hope that it works, without the bootloader unlocked there's gonna be nothing you can really do.
So I keep typing it till it shows true for "Device unlocked"?
I typed it 4 times now....it still doesn't say Device Unlocked True...

It isn't going to work. You're only other option is to try this:

I know you're not hard-bricked but this is likely your only chance to get the phone working again.

I tried using the method but I'm not sure why it isn't working. I ran the program and it gave me a few problems letting me know what's wrong with my phone:
userdata_64G.img: FAILED
boot.img: FAILED
persist.img: FAILED
recovery.img: FAILED
system.img: FAILED
I'm running near the end where nothing is going my way and I may need to either ask someone to attempt to fix it or buy a new phone...
My N5 decided suddenly the other day to stop working. I held it, it turned off and on and then the boot animation just continued. I have googled and tried everything I can but it seems to go wrong someplace every time. I tried to wipe it from recovery mode but then it gave this as "error message".

is your device even root?
Is the phone running a stock or custom recovery such as TWRP?
You may have to try flashing a stock ROM but that will require an unlocked bootloader.
Being rooted should not cause a problem with formatting the data and cache partitions.

Yea it is running custom recovery TWRP, was a long time since I played around with this. The bootloader is unlocked if it is "LOCK STATE - UNLOCKED" is bootloader. I don't know why it doesn't work, but I belive the problems is that the mobile can't find cache. Will take it to service and if it isn't my fault it will be covered by the shop. So regarding the last thing, do I have to lock the bootloader or do the warranty work anyways? I'm a noob at this just FYI

You should download "Nexus Root Toolkit" to your PC. There is a function in the Advanced Menu tha will allow you to fix a boot loop/soft bricked.
I hope that helps

It's a great source....
I'm not sure but locking the bootloader may not make a difference for warranty if the phone has TWRP installed.
Have you tried using the Nexus Root Toolkit? There is an option to restore factory and unroot, with a bricked unit. This helped me once, although not with your particular problem.
I had same issue with MOTO G 2014. Motherboard replaced on warranty. I suppose there was prob;lem with flash memory.

I have already tried to use that option and have used Nexus Root toolkit before. Will give it another shot though. Will update.

ADB device not found.. Aparently I can't do it because USB debugging seems to be off, but I can not access settings to change it...

Your best bet is to get a fast boot cable and use direct fastboot commands
Try using the flash-all batch file using a pc with the phone in fastboot mode. If that doesn't work. If that still doesn't work, it may be that the emmc in the phone is damaged.
What is a fastboot cable? I've got a couple of nexus 5 motherboards with booting problems. It would be great if I could fix them. Thanks.

hey guys, my phones bricked to the max due to an update to cm13. here are all the issues:
-settings doesnt work, at all
-google play services doesnt work, like not even installed on phone anymore
-status 255 when i try to flash any update
-factory wipe fails
-wipe cache partition fails
so i looked online about what status 255 is and people were saying to flash a new super su to the phone, so i tried that, and now the phone doesnt boot up. so i dont know what my options are now that i cant put any files onto the devices from pc because it wont boot, and flashing from recovery doesnt work.
any ideas?

Your best bet would probably be to flash back to a completely stock ROM and start over with CM. Be aware of the fact that flashing back to stock will require wiping the data partition.
