Won't Boot - Nexus 7 Q&A, Help & Troubleshooting

I was on stock 4.4 rooted with Franco Kernel. I tried using Wugfresh to return back to stock, after trying I just get Boot Failed when I boot or try recovery. I'm not the best with Android so any help would be great. I have tried downloading stock 4.4 Rom from Google and flashing via Wugfresh but still the same. I'm worried I can't use again now.

N73g not rooting

OK little preface, when I got my N7 I updated to 4.2.1, unlocked the boot loader and rooted with no issues. I found the zip for the 4.2 tablet ui and flashed it though TWRP. For whatever reason that soft bricked my N7. I completely spaced making a backup so I was stuck. I was able to flash the stock 4.2.1 firmware and got it back up and running. now I am trying to reroot my tablet but it's not working. I've tried flashing the superuser zip through recovery and also tried using the toolkit to push the needed files and nothing has worked so I'm at a loss

Xda is not your personal tech support. That being said, flash stock and fastboot OEM lock.

Can't start any Custom Rom

IT seems that any custom Rom I load just sits at the startup animation on first boot. None will Load. I can revert back to Stock without a problem.
Any Idea's?
You need to provide more info. Which stock version are you using? what bootloader version you on? What roms have you tried, and what are they based on (4.1.x, 4.2.x) ? CWM, or twrp?

Started with 4.2.2, used the nexus 7 tool kit to perform root, install recovery, etc. Using twrd 2.4 fir recovery. Smooth rim was the latest. Tried 2 others but the names escape me right now. I have rooted and loaded custom rooms on my last 3 phones so I am not s complete noob but am not an expert either

Help upgrading nexus 4 from 4.2.2 to 4.3

Hi, I own a rooted nexus 4 currently running 4.2.2, I just tried to install CM 10.2 and it went to a boot loop, so I restored a backup and its stock again (with cwm recovery)...
What should I do? What can I be doing wrong?
Sergio, computer no work what wrong?
Flash the new 4.3 bootloader and radio using cwm. Then do a full wipe and flash your 4.3 ROM of choice.
Downloads: bootloader and radio.

[Q] Very Strange Problem

Hey all, I'm having a problem with my nexus here and its driving me crazy. Basically i was behind on updates and running 4.2.2 (Paranoid Android) until today. I decided I would upgrade to the newest Paranoid android 3.99 RC2. First off, i downloaded the stock nexus 4 images, and flashed em all through fastboot. Then i flashed the newest CWM (6.0.3.8 i think) and proceeded to flash PA.
But when i booted into PA, i had no cell connectivity as well as unknown baseband, imei, and imei sv, even though the baseband is clearly shown in fastboot (its 0.84). I tried reflashing the baseband, no luck. So i reflashed the stock google img's and my imei and everything came back.
So i tried a second time and it still didn't work. Seems like whenever i flash PA, i lose my imei and baseband.
Help me out guys
Anybody?

DID you do a full wipe before flashing?
I would be very careful and stay stock until you get an answer. Without IMEI your phone is illegal and won't work. I've stayed away from C /M as it's buggy and has too much trouble, like this.
Sorry

If you are coming from 4.2 make sure to flash 4.3 Radio and Bootloader!!
Follow this guide:

Yes, I did a full wipe, even the SD.
I flashed the full 4.3 stock Google image through fast boot first. So I should be totally up to date.
I will try TWRP and see if its the new CWM that's messing things up.

The CWM version you used has a bug which derps your baseband when you flash anything. Simple fix: install any other version of CWM or use TWRP, then flash everything again (radio, rom, whatever). This happened to a lot of people. You'll be fine.
