Nexus 5 crashes and doesn't open - Nexus 5 Q&A, Help & Troubleshooting

I have waked up and noticed that the phone is stuck on google logo, i tried to restore factory settings but that was not applicable
so i followed that post http://forum.xda-developers.com/showthread.php?t=2513701 to unlock the bootloader and install factory rom
after several tries my mobile phone can't start and when it starts the apps begin to crash one after the other, I noticed that the mobile recognize a memory of 250 MB (although I have a 32 GB storage) and I think thats the problem
Now I can open the recovery mode but the following errors appears:
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
E:Can't open /cache/recovery/log_log
E:failed to mount /cache (Invalid argument)
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install

So I don't know what to do!!!!! please help

The internal flash memory module (32GB) of your phone.

Same thing happened to me. Was stuck in loading screen. Reset to factory settings. My apps would crash and I cant connect to my network. I also followed that same guide but it didn't help.

Yep, phone's internal storage is probably dead. RMA!

Just curious: for how much time did you use your phone before crashing? Was it completely stock?

[Q] Moto G CWM problems

Hello I am a user of the Moto G
I tried to install Lego Rom, but it was stuck in a bootloop
I reboot into CWM to restore my backup of my stock rom and CWM will not mount anything
E: could not mount /data to setup /data/media path!
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
E: Can't mount /cache/recovery/last_install
E: Can't open/cache/recovery/last_install
How can i fix this?
Thanks
That is a known bug with CWM, regarding proper permissions not given or data not being mounted.
There is a fix, but I didn't quite understand it, so I just switched to TWRP.
Its much better IMO.

Yeah, you can try reflashing stock and what not.... But if you just bought it... I'd get it replaced instead.

Friend od mine had the same issue. It is emmc failure. There is nothing you can do about it. Had to be send for replacement. In other words flash memory is dead.

Try flashing just the cache partition through fastboot.
Code:
fastboot erase cache
Code:
fastboot flash cache cache.img

Try relocking your bootloader with fastboot oem lock, them reboot the bootloader. If it stays locked, then try LG Flashtool. If it reverts to being unlocked after the reboot then your eMMC is damaged and you'll have to RMA.
Well, my Nexus 5 had a similar problem, but mine was unable to mount /persist.
So all thanks to this, my Nexus 5 was saved. You might want to try this if that doesn't work.

It is by default locked.when i hit fastboot oem unlock,bootloader is unlocked but after reboot in bootloader it stays locked.Does LG Flashtool works in my case?

Probably not but you can try. Most likely you'll have to RMA.

[Q]Datawind UbiSlate 7c+ edge tablet cwm loop

I flashed my ubislate 7c+ edge with the wrong recovery, and i believe it wiped all partitions.I have already tried every possible method found in any nook and corner of the internet.
I'm stuck in cwm recovery loop, it will boot to nothing but cwm recovery.
LiveSuite isnt working, i have like 4-5 images out of which atleast ONE of them must be the correct firmware(all of these i found on xda and the internet which was said that it would work) BUT none work since partitions are gone...
recovery says like cant mount system
cant mount emmc.... etc
Pheonix card doesnt work either, shows sprite error
I can make neither head nor tail of it.
Can anyone show me a way with which i could manually fix this tablet by either writing the partitions manually somehow or doing some magic trick(lol)? Please enlighten me.:crying::crying::crying:

Edit : Hot news !!
After months of pure hopelessness ! I opened my back cover(for the 3rd time), moved the sticker and noted the board number(pcb number i guess?).
A sticker was covering it from being seen lol ! I noted it and googled the number.Found 3 firmwares for it. The first showed nothing in livesuit 1.07. Went till 3% and nothing happened. In livesuit 1.11 it showed x162 error(for a gazillionth time).I was hanging on the edge now. Had downloaded only 2 firmwares.
Tried the 2nd one and boom ! it went past 4% and i watched with glee as upgrade succeeded!! So my partition was wiped, but this managed to rewrite it.(Pats myself).
No datawind logo on boot. Everything works perfectly.
Link to working rom.I'll never try to upgrade this thing again lol .

Dude. You need to flash ROM via livesuit. Nothing else will work I promise.
Unzip that file and you will find the image to flash.
Good luck.

Recovering data from Bootloop?

Hi all,
First of all, my phone is completely vanilla, no rooting or modifications were done. Running 5.0
Here's my situation:
After fully charging the phone yesterday and sending some messages on whatsapp, I drove out to get food and while on the way there, the phone blacked out. At first, I was able to get to the colored dots loading screen but it would always get stuck there and shut off. Then I keep trying to restart it up and it got worse and worse, now I'm always stuck at the GOOGLE screen. I'm not sure if this is a boot loop issue as it just gets stuck at GOOGLE screen. I tried the recovery mode cache wipe and it gets stuck at the GOOGLE screen in the middle of the wipe, or blacks out.
So this morning, after fiddling around the power buttons some more, I am able to get the battery logo while charging, though it is weird that it shows 100% then completely drained the next minute or so. I try to load into the recovery mode again and this is what I see at the bottom
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/log
E: Can't open /cache/recovery/log
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)
Am I screwed? I'm not sure what to do at this point.
Today, I am stuck at the colored dots boot animation but after smacking the power button side a bit, I'm back to being stuck on the Google screen. What's worse the recovery mode can't be maintained on the screen as it blacks out after 5-10 seconds. What can I do at this point?
I was going to use WUGfresh to reflasth the ROM but I think this wipe all data on he phone? Is there anything I can do at this point to retrieve all my apps, photos and what not? Nothing is backed up.
Any tips or advice would be greatly appreciated.
Thanks
