[Q] Need help flashing img via Fastboot - am I bricked?

Had just flashed the latest CM9 nightly (clean install, fresh wipe) yesterday and everything was running fine.
This morning, woke up, my phone was turned off. When powering it on it hung on the google screen. Fastboot still working, booted into recovery only to find that I would get error messages when trying to load my backs "E:unable to mount /sdcard". Apparently it also couldn't mount /data. So I was unable to flash any images or restore or boot up.
Seeing that fastboot was still working I assume I'm not bricked yet. I tried flashing a new boot and cwm recovery via fastboot - no dice. Same errors.
I don't have a recent backup of anything in sdcard, but at this point I'm willing to sacrifice it.
Found this thread http://forum.xda-developers.com/showthread.php?t=1078213
and I'm trying to follow the steps to flash back to stock GB. using the GRJ22 images
It flashed the boot and recovery without issue but seems to hang while flashing the system.img. I know it's a big file, but it was up to ~2hrs with it still transferring. I pulled the plug on it and tried again, lost patience after an hour.
Now I had the idea of maybe locking and unlocking the boot loader would help things.....not sure why I thought this. Anyway, now it seems to hang on the unlock bootloader screen.
So my question now - am I screwed?
- anything else to try?
- is it really "hanging" or do I need to give it more time?
- have I screwed myself even more by now locking my bootloader and flashing the stock recovery?
Any help would be very much appreciated....

Some new additions and new insights from the reddit android community:
- this probably has nothing to do with CM9. My phone has been wonky for about two weeks - random reboots, sometimes rebooting into recovery. That's why I thought I'd throw on the latest nightly and do a fresh wipe yesterday.
- There's definitely something up with /data. Anytime I tried wiping all/factory reset in cwm recovery I got errors about not being able to mount /data or being able to find files in /data
- basically anything I do involving /data partition causes the phone to lock-up -- flashing the boot.img and recovery img worked, but not system. Also, I think the reason I can't re-unlock the bootloader is because during the unlock process it tries to do a factory reset/data wipe
Basically I think there are two things I need to know if I can do - 1) unlock the bootloader again, via some way that won't try to reset the /data partition and thus won't freeze the phone. 2) try repartitioning /data
I really hope I didn't screw myself by locking the bootloader. I'd actually feel a lot better if it was something in my phone that just failed hardware-wise rather than something I could've fixed if I wasn't too quick to try poorly thought out ideas.....
Any help at all would be appreciated!

Possibly (and likely) a corrupted nand flash. Fairly common problem sadly. I'd say it's a good thing your bootloaders locked, no dramas sending it back to samsung. It might've been possible to reset the partitions and flash fastboot images but i don't think i've seen anyone who has done this to sort any similar problem. Hopefully your phones still under warranty

Well thank God that it turns out that I'm still on warranty.....sending the phone back to Samsung tomorrow.
Like you said, it's actually a good thing the bootloader is now locked and the stock boot img and recovery img are now back on! Hopefully this makes it more likely that they weren't turn away my phone.

I've yet to hear someone not getting work done under warranty because of an unlocked boot loader but it's always good to have it as stock as can be. Hope they don't take too long with your phone.

[Q] after installing 4.4.1 - no cellular + data - SOLVED

SOLVED! see solution in the first comment.
I really need some help...
I installed manually 4.4.1 version using this guide: http://forum.xda-developers.com/showthread.php?t=2523217
(I am having a rooted device with TWRP without any modifications or deletions - used section B)
after the install successfully worked, i chosed to wipe. it was stuck and i used the powerbutton to reload device.
when the device turned on it used emulated storage which means no imei and no efs.
using the twrp (in recovery mode) i can see my full data and efs files.
when i am trying to rewipeqinstall update i get this error: "E:/Unable to mount /cache"
please help me.

Do not turn the device off while clearing the cache.
Reboot to recovery, go to TWRP settings and enable rm -rf option, go back and wipe the cache/dalvik. If THAT doesn't work, you will need to flash the cache.img from the factory image found here http://forum.xda-developers.com/showthread.php?t=2513701
After you do that, make sure you have the latest version of TWRP installed (2.6.3.4) If you don't you can also choose to install that via ADB before clearing the cache.

First of all - thanks for help.
already tried the rm -rf option unsuccessful.
2 question before I'm starting the flash process:
1. Is there a way dumping the efs folder to my computer before?
2. is this the command i should use: "fastboot flash cache C:/image-hammerhead-krt16m/cache.img"?
thanks a lot.

1. Use TWRP to back up your EFS data if you would like. You won't lose any data by just flashing the cache though. All your apps and everything should still be there.
2. If you installed the drivers correctly and that is the correct directory for the file on your computer, that is right! I put mine on the desktop for simplicity.

clearing cache/dalvik is very slow on N5, I found, and so is resetting the phone in recovery. though the progress bar may not move the process isn't stuck, it's still going on in background.

Flash the newest version of TWRP. The issue is fixed.

yeah i have a rma out for mine. Luckly i have a spare phone (its a damn $15 go phone) but mine is already shipped. biggest issue is the $440 is tied up in my account until they get the bad phone back. basically i would suggest to anyone that if they are going to flash a rom first thing they should do is back up their efs to their pc and also some sort of could (dropbox, drive, mega, box, etc).

Well in our case I have my efs on my PC from weeks ago restoring it doesn't fix whatever the ROM changed lol

[Q] Recovery is broken??? I Don't Know.. Please Help

So I bought a Nexus 5 off of craigslist for a pretty good price about a week ago and he had already rooted and installed a custom recovery onto the phone. He had some sort of rom that I didn't like so I decided to flash my own. So I downloaded cyanogen mod (the latest nightly build at the time) and flashed it along with g apps and rebooted the phone. When I it was turning on it said "upgrading apps xxx out of xxx." I was very confused because coming from a Nexus 4 and flashing many ROMs I have never seen this before. When the phone finally powered on it started giving me errors every 5 seconds and I realized soon after that I had my previous apps from the old rom still installed and everything else was in place. I managed to get into settings after clicking ok to errors every 5 seconds and saw that my ROM did indeed change to Cyanogen Mod. I decided to try to factory reset the phone through the settings menu and that fixed the phone seemingly until today. I tried installing another rom but this one is giving me multiple errors and then rebooting my phone. I could not get into the settings to factory reset the phone through there.
I was thinking that maybe the recovery was broken but I'm not sure of how to fix it. I tried to find a flashable recovery but only found IMG versions which I don't know how to install. Is there a possibility of any other issues? I am resetting/wiping cache/wiping dalvik cache every time in that order. When I'm installing the roms it says something about e:/ volume not existing or not being found could that be the problem? I don't recall ever seeing this on my nexus 5. If anyone knows how I could fix this issue I would greatly appreciate your help.
Thanks, Alex:laugh::laugh:

Did you wipe data and cache before flashing the new rom?

This happened to me loading some ROM previously. You need to make sure that you do a factory reset and wipe the cache and dalvik. I also redownloaded the ROM just to be sure but I do not think that is necessary. It sounds like you dirty flashed. Is the recovery Team win? If so there is a setting under mount that you need to uncheck and it is called system.
edit: I re-read and saw that you are wiping the cache and dalvik cache, by resetting do you mean you are factory resetting? The img files are for you to do through the command line in fast boot and you can find out more by clicking this link: http://forum.xda-developers.com/showthread.php?t=2507905 and also this link: http://forum.xda-developers.com/showthread.php?t=2513701. <--- familiarize yourself with both of those threads and you will be better off than a lot of people that come asking for help. Not saying that you are not well off just knowing is good for the soul.
2nd edit: Since it sounds like he did not wipe the SD card were there good things on there?

I see your doing a clean install. I'd return it to stock and start over, especially considering you bought the phone used. Who knows what's been on it. See this http://forum.xda-developers.com/showthread.php?p=47156064

I see. Well, if you really did do a factory reset before flashing a new Rom, then maybe you have an old version recovery, or something is borked with your phones partitions. Honestly, buying a used one like that, I would do a full factory restore by flashing the stock images(sticky in general for directions) but don't relock the bootloader. This will erase everything and repartition the phone. Then install recovery and flash away.

Good. Glad you got it worked out. Was probably an old build of whatever recovery and because of the way KitKat changed things, there were a lot of problems wiping when the phone first came out. If you find any more good deals on your local Craigslist, PM me. I want a black n5 instead of my white one.

Have you flashed the cache.img? Try flashing it 2-3 times... Or just head over to stock recovery and format cache 2-3 times and then do a factory reset.. These things needs to be done via the stock recovery and not a custom one.
I had a similar problems some weeks ago and this solved it!

i live in norway we cant send them to google directly it has to go trough the company where u bought it, say for an example my carrier telenor which would then deal with the problem. but i bought mine of ebay because i wanted it faster (due to problems of the 2012s nexus 7 where we didnt receive it before november.) so i guess the phone is pretty much useless now?

i had the same issue when running the Nexsense port. There was a known issue that it would break the sensors back when it first got released but the DL link got removed immediately. after that there was a post to correct the sensors. but there was another issue with it as well. seeing as it was a NAND backup, it was very possible it re-wrote you EFS partition on your phone which stores you IMEI and other data like that. The only possibility of getting that back, is if you did a backup of the EFS partition prior to having an issue. just a warning: DO NOT FLASH ANOTHER PHONES EFS PARTITION TO YOURS. the only way to get the phone to work again with a messed up EFS partition (from what i have seen) is through replacement device unfortunately

Updating to 5.1.1 made phone stuck in boot animation

Hi.
Yesterday I got a notification to update to 5.1.1. ( My nexus 5 was on 5.1, everything stock, never flashed anything before )
I selected 'install' for 5.1.1, and left my phone aside. After a few minutes I saw that it was in the boot animation. I thought it was the process ongoing. Several hours later I decided to restart the phone manually ( obviously something went wrong ).
After rebooting, again, it's stuck there. On the four colored dots swirling around.
I searched on forums, I got the 5.1.1 stock, got ADB, fastboot etc, flashed as the instructions said ( via ./flash-all.sh and via the long version by manually flashing every partition ) EVERY time the same thing, when I boot it's just showing the boot animation forever.
Any idea on what's wrong?

Tried 'Wipe data/factory reset' a couple of times.
Also tried 'Wipe cache partition' later.
No difference at all. It stays for hours on the booting animation.
Can I somehow see the logs or something to see where it's stuck?

I believe you must flash factory images at this point. Just make sure you backup SD Card data or flash each partition manually skipping the userdata.img (this one erases internal storage)

Well I did that, I tried 5.1, 5.1.1 and the M image.
None of them works.
At this point I'm tired of doing the whole process every time and waiting for 15 mins to see if it worked.
Thankfully, I called google support and they will send me a replacement.
I'm just very curious how this whole mess happened from a simple OTA update.

If a complete wipe of the phone with factory images didn't fix it sounds like hardware. Possible corrupt NAND I think.

Possibly.
In any case, they already sent me a replacement phone.
Google support has been extremely satisfying.
