If you can get into fastboot and have used the one click root, then cwm must have also been installed so you should be able to boot into recovery and restore the backup you made.
If internal storage has been wiped then you can download the factory image from google and flash it via fastboot. After that re-root, and start from scratch again.

wait until ODIN stuff appears

Follow my directions to recover from an unbootable device. Read the whole thread because there is instructions on doing it from a PC within the thread.

[Q] Help, boot issue

Hi everyone,
So I have never ran across this issue before. I haven't had any problems with my device and yesterday I wanted to test out the new Jelly Bam update rom from their site. The rom would not boot pasted the "Google" spash screen so I rebooted in to recovery and did a full wipe and restored via backup to my previous rom just like normal. Well then I noticed that normally when I connect my phone to my computer I see my internal memory drive pop up which I am able to click on and then access my files, but this time when I accessed it I have a hand full or folders like 0, twrp, android, etc and I had to double click on o folder to access my memory with all my files. I thought that was weird so I went on about my day. Later I tried to do a fresh install of my current rom PACman but even after doing a fresh install the phone will not boot passed the Google spash screen, and now twrp doesn't even see my backup file because its being directed to this new partition with all the folders I was talking about. I even tried using the file manager in twrp to move the backup to that twrp folder but twrp doesn't even see it.
So as of right now I can get in to twrp but I can not boot my device pasted the google splash screen. I also can't access my memory through my pc since nexus does not allow it with twrp. What do I do? My thoughts are that something got screwed up with the partitions when I flashed the Jelly Bam rom so I will need to go back to stock, does that sound about right? I was thinking of following these instructions to go back to stock and then move on from there, any thoughts or alternatives? http://www.androidrootz.com/2012/12/how-to-unroot-nexus-4-to-stock-42-jelly.html
Thank you
Trying this method to return to stock: http://www.wugfresh.com/nrt/
If no one has any input I will assume I am following the right path.
I flashed factory images a couple weeks ago and in order for TWRP to see the nandroids I copied back to my phone I put them in the following path: /sdcard/TWRP/BACKUPS/stringofrandomnumbersandletters/
Are your TWRP backups in a similar location?
If you've decided to go back to stock, I'd suggest using the following guide by efrant... http://forum.xda-developers.com/showthread.php?p=34552123

It is twrp fault. That recovery is crap to be honest.

It looks like twrp is now looking at my twrp folder in my sd card 1 not sd card 0 where I have had my backups and all my files. After trying again, I moved the TWRP backup to the sd card 1 twrp folder, twrp recognized it and I restored from backup....but when I reboot I am still stuck on the Google screen. Not sure what to do.

Since I can't move anything to my memory, any suggestions?
If you've got adb and the proper drivers installed on your PC you could try:
Code:
adb push ROM.zip /sdcard/ROM.zip
from the command prompt. Obviously use the name of the actual ROM.
Edit: ignore that, just read the post where you managed to restore! D'oh!
Have you tried clearing both caches?
The only issue is that my phone is not recognized as having debugging on when I use the Nexus Root Toolkit. Would it matter trying to push via adb? Also with your code, can you specify exactly what I should type. Mine shows C: \Users

If I were you I would not rely on a toolkit at this point. If you boot into recovery you can use adb commands to push the files from your computer to your phone.
Edit... Spec-Chum's suggestion of wiping caches is a good one. Have you tried that while booted into TWRP?
You could also try the following from within TWRP:
1. Factory reset
2. Wipe system
3. Restore nandroid backup
4. Wipe caches
5. Reboot

And that's were I am stuck right now. I am not a pro at using adb commands, never used it till I got my nexus 4. Right now when I launch the cmd it shows "C:\Users\My User Name\Desktop>", not sure where to go next. I guess I am not sure what I should be pushing at this point either.
Oops...it seems I was editing my post at the same time you were responding to it...take a look at my previous response again
I'm fairly new around here but I can help with the adb commands if you need. Hang in there

Yeah. I tried wiping cache/dalvik/system/factory reset and then both restoring from backup or flashing the latest PACman rom which is in my sd card. Right now I am reading the http://forum.xda-developers.com/showthread.php?t=2018179 guide to see if I can use adb to flash my rom or another recovery. Makes sense if its the recovery not letting me flash anything, but i'm not a dev. At least I am able to get in to recovery to begin with, good sign I guess.
If you can boot into bootloader and recovery there are many options to help get you up and running again. That guide by Jubakuba is really good but if wiping and restoring your backup from within TWRP didn't work I would highly suggest reading efrant's guide on returning to stock...I posted the link in an earlier reply.

Nope, doing a fresh install didn't work. Now its time to restore to stock. ......
One problem:
"
5) Extract the files from within the .tgz file which you downloaded in step 3 using 7-zip, not WinZip or WinRAR or whatever.
6) Make sure you have extracted ALL the files (including extracting any files in any archives inside the .tgz file). You should have six (6) files ending with .img in the directory you created in step 1. The other files you extracted from the .tgz are not necessary;"

Its weird adb will not work on the computer unless the files are in the platform-tools folder in androi sdk. trial and error, just finished flashing system....
should I do this command, I really don't want to lose my stuff:
10) Optional (NOT optional for n00bs) -- Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
Well, I didn't and finished the process...did a reboot when I was done...now its on the Google screen...just waiting....I'm seeing a Nexus X splash screen!!!...
Update: Its taking a very long time, hopefully it works...going to give it another 10 mins
And we have BOOT... thank you everyone! Now I have to root this sucker!

If you can get to the bootloader/recovery you're not bricked.
The moment you can't do anything with your phone except throw it at somebody is the moment its bricked. You are ok my friend as posted above just flash another rom but I am confused if your phone would only go into recovery why would you not try and restore backup or just flash another rom?
Edit: Hopefully you made a backup of your original rom? Also what recovery are you using

accidentally wiped everything after getting stuck in boot loop

As per the title, I accepted the system update on my rooted ls980 (didnt know it would mess anything up). Ended up putting me into a boot loop to TWRP recovery. Tried to restore all my backups and none of them yielded a different result. Thought i would try a quick wipe but i accidentally wiped everything... For some reason when i try to install the newest USB drivers it tells me the install worked but never recognized the phone. I have done all the steps in this thread http://forum.xda-developers.com/showthread.php?t=2432476 but not everything installs when plugged in from download mode. Also could not get LGflashtool to register properly. I'm not exactly sure where to go from here, I have no roms, backups, or adb access. what do?
Well if u can boot ur rom into recovery, then connect s pen drive with s flashable rom inside to ur mobile via OTG cable, and then flash

you can either format data in cwm or in stock recovery format data/reset
or if that doesnt sort the boot loop quickest way to solve it is just to flash stock rom via odin
Remember next time before you do anything like flashing a mod or trying out something different to always make a nandroid backup in cwm - this way if you get into a boot loop or want to revert what you have done you just have to restore your nandroid backup
anyway stock rom firmware is found on my thread below

follow the instructions fully on my thread
you need to install the usb drivers
you need to put your phone into download mode (vol down home button power button)
cwm is not required and not used to flash stock rom via odin - you must be in download mode NOT recovery mode

How do I download it to my phone if I cannot boot into it. Is there any way I can copy a zip file (rom) onto the phone's internal memory.?
Your phone should boot into recovery, so as long as it goes on and boots all u do u is use ur pc to move file over and flash it...

Boot into bootloader (hold power and system on), flash the though recovery through adb, mount your .zip,, flash your .zip through recovery. Sorry if that doesn't make sense, I've been drinking with the roommates, lol.

The same thing happened to me also! The whole /data (incl. sdcard) partition went corrupt (showed up in TWRP as eemc instead of ext4) & the /vendor failed to mount.
First I had to repair the /data partition (unfortunately the data was lost, as it repaired to a blank partition). I ended up having to go home (was at work at the time) & hook the phone up to the PC & download the ROM & transfer it onto the sdcard. I'm not entirely sure why/how this happened, but I believe it was because a corrupt vendor IMG. Although that theory doesnt include why the /data partition corrupted, it only explains why the /vendor partition failed to mount.
Fastboot flash system system.img

I have the same issue. The problem is, that my computer will not recognize the phone in bootloader mode or in recovery mode(MTP enabled). How can install usb drivers without being able to boot into phone OS???? I've tried Nexus Toolkit with no success. Please help?

So I did the same thing. I'm sitting in TWRP right now but have nothing on the phone. Will I be able to reboot from TWRP into the bootloader and just use the flash-all command to get my phone to boot back up, then just go through the process of custom recovery again?
Basically I'm worried about leaving twrp without an OS. I didn't wipe bootloader did I? Also, I tried to download a ROM and just drag it to internal memory, but I can't seem to add anything to the internal memory.

Hi... Just boot into recovery and reflash system.img from the factory image of your choice in bootloader with fastboot. Also flash the vendor image from the same factory image. Done...
Or reflash the whole package with flash all (manually is better imho). But you'll waisted time... Let your phone reboot into Android and you'll have your internal storage back.

Yes TWRP has a reboot to bootloader option available. So you can access fastboot via bootloader to flash the necessary images. Just don't forget to re flash TWRP image again in case the stock recovery image was flashed beforehand.
The odd thing was that I did choose that option to boot to bootloader in twrp and it didn't work. I ended up having to reboot to bootloader manually. Not a big deal. All is working now, but thought that was interesting.

Exactly which partitions did you wipe? system? data? Internal Storage (userdata)? all of the above? Hopefully you did not wipe userdata (all your stuff). Were you on a stock ROM? You should be able to d/l the Google image from the same build you were on, extract system and data and fastboot flash those. Don't flash userdata. All your stuff should be there. Follow the tutorial on how to set up fastboot and selectively flash partitions.
