No operating system installed

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.

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.

[Q] Is it safe to flash Cyanogen 10 on top of a non-stock kernel?

Hi, if you're reading this, thanks for taking the time to help me. I want to flash Cyanogen 10 on to my rooted Nexus 7. Its currently running the stock JB 4.2.2 ROM. A few days ago I flashed the motley kernel (build #249 for Jellybean 4.2.2) to OC the CPU to 1.6 Ghz using ROM Manager to flash and Trickster MOD to OC. I understand how to flash Cyanogen 10 to the Nexus 7, but is this safe? I've heard some users report that they get a boot loop when trying to flash Cyanogen 10 on top of a modified kernel. Has anyone here experienced a problem doing this?

The kernel lives in the boot partition and that is formatted when the new rom installs and it flashes its own boot.img into place. No worries. Just make sure you do a factory reset and wipe system prior to flashing cm10.

Okay. So I should boot into recovery, then do a factory reset. After that, unlock bootloader again and re-root. Then install Rom Manager again, and flash CM 10, then flash motley kernel?

A recovery factory reset does not relock or unroot your devices. Pretty much every rom out there will be pre rooted. So what you are going to do is download your rom, boot to recovery, perform a backup, factory reset, format system, then flash rom and gapps package and kernel, then reboot.

Oh awesome. Thanks for the help!!

[Q] possibly fully bricked phone need help!

I went from Paranoid Android 4.2.2 to the first Cyanogenmod 10.2 nightly and my phone worked great on the first boot, after rebooting it gets stuck on the google screen. I have tried going into recovery and wiping it etc. re-flashing stuff and can't, I have tried using the root toolkit to revert to stock 4.3 and unroot and 4.2.2 and unroot and neither has fixed it. I've even tried manually reverting to the stock bootloader etc and nothing. Theres no option for mounting storage to the pc with TWRP so I can't try redownloading the CM10.2 zip file either.
The point is I really need help as I think my problem is a rare case I can't find on the forums already.

Have you tried MANUALLY restoring Google's factory images? (With the fastboot command.)

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.

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.
