Well, you just erased everything. Try using ADB sideload to flash a ZIP instead.

Tanks for answering but I solved it with nexus root toolkit and CyanogenMod installer.

I tried to install a new rom after updating TWRP 2.3.0.0. after all was complete it stuck on the boot screen. I then tried with the Nexus Root Toolkit to use a restore from backup. Same problem. I then tried to flash stock and unroot. Same problem. I then tried a number of things through TWRP from backups I had their. Same problem. At present I have no OS and I can only boot into TWRP, turn if off or look at the GOOGLE screen. I have run out of ideas and would appreciate any help offered.
If you have tried everything else (flashing a ROM zip etc.) Then you should flash the factory image from Google.
Don't use the script/batch file as that will wipe your internal storage.
Just flash system and boot.

Sometimes a rom takes a long time to boot for the first time, please be very patient. Also, try wiping everything from /system, and then re install a custom rom from your /sdcard partition. also make sure your roms are for the nexus 7 not galaxy nexus or other similar devices. ONE MORE THING 4.1.2 wont flash with 4.1.1 bootloader.

Adb push a ROM.

I know many people hate the talk about toolkits but I was in the same situation and I used Wug's toolkit and it saved me. I downloaded 4.1.2 image directly from Google, as the toolkit only has 4.1.1.
I tried to return to stock on my own and it just went from bad to worse. I would of spent more time trying to fix it on my own but I was on a very tight time constraint. It will unroot your device but it is easy to root again.

THANK YOU the "ONE MORE THING" is all I needed to know for the same problem!
Hi guys im sort of new to the android scene and im having problems with my nexus 4, i downloaded the newest cyanogenmod nightly and flashed it, it messed up part way through. i rebooted the phone and now its just stuck at boot animation. i have wiped the cache the dalvik cache and done a factory restore.
i have tried reflashing the nightly but it stick stops part way through, i want to add the new rom to the /sdcard but i dont know how, its not showing in android file manager and i have tried using adb push command.
im sure its a noob question but any ideas?
P.s sorry i know there are posts similar to mine but tried them and wont work
If adb push won't work in recovery you might try flashing the factory images with fastboot. System.img is really all you'd need.

You can try to sideload a new ROM via 'adb sideload' in the recovery.

Follow the steps, but only flash the system.img. Once it boots, move your ROM over. Reboot into recovery. Flash.
I had the paranoid android rom on my nexus 4 and i tried to install a new rom. the zip must have corrupted because while installing it it failed. And now it wont boot. It goes to the google screen, shuts down, then launches into the twrp menu. Yes i factory reset and wiped before i tried to install. What can i do? I have no bootable rom on my nexus 4 right now?
anyone? Basically my nexus 4 wont boot. I want to mount the nexus 4 using twrp so i can trasfer a rom file over but it wont mount. Any help?

Did you try a 4.4 rom by any chance? there are 1,000's of post to use CWM to be safe, and did you back up you previous rom to restore from TWRP?
If you still have a 4.4 rom zip on you device look for help on flashing CWM http://forum.xda-developers.com/showthread.php?t=1993331
If all else fails you can also try a factory reset http://www.wugfresh.com/nrt/ there is an option to tick on soft-bricked / bootlook in Wugs toolkit.
You can't "mount" your nexus 4. You can use adb to push the appropriate zips over. Or use fastboot to flash .imgs.

Yes i did try a 4.4 rom. I noticed that soft bricked thing in wugs toolkit right before i saw this post, so yeah thats what im doing right now. I should have tried the flashing cwm thing because i do have the 4.4 rom on my device, but ill just wait until google releases it or its stable.

I'm using the Nexus 5 port atm and it is stable, i used to skim over the instructions but that extra 5 minutes of reading the flashing instructions will save you hours of searching for a way to get out of a error.
3 options:
1. Adb sideload the things you'd like to flash.
2. Adb push the files onto the device while in recovery.
3. Fastboot flash the factory images.
Hello
My nexus 4 gets stuck on the google logo then boots into cwm recovery after I tried to install the stock 4.4.2 rom, I was coming from PA 4.3 rom.
The install aborted itself. I
wiped everything before hand and tried to install the rom again and still have the issue.
I downloaded the 4..3 stock rom but I don't know how to get it into my phone. I am on a mac and can't clear adb instructions.
I think I may have bricked my phone. Can someone help me find a way to fix this?

Can't help you on the Mac, but while it's unnerving, don't worry, your phone isn't bricked. Search xda for Mac adb setup and go from there. Good luck.

if u can get into recovery then its a great sign....put some custom rom onto ur computer's internal sd card by mounting usb through recovery...if it isnt letting u mount then try http://forum.xda-developers.com/showthread.php?t=1917237 to setup adb over mac
Maybe run Windows in VMWare?
