Help: Nexus 7 boot problem-kernel/rom issue

[harrycarry250]

Hey there! I was updating my version of Paranoid Android and my kernel and it seemed fine at first but It yield some odd problems. I went into Clockworkmod recovery and Flashed my rom and kernel I then proceeded to wipe my cache and dalvik cache. I have done this many times before on many devices. I encountered a problem when I rebooted for the second time, I got the Android is updating apps display and I continued to get it every time I booted. The device would also randomly turn off when the screen dimmmed. I proceeded to set out and fix it. Here are the steps I took and the problems it caused.

Flashed stock rom-would not boot properly

Flash RESET kernel-I messed up and though this was a real kernel, my problems escalated from here.

Flashed stock rom and recovery.

Flashed reset kernel and then real kernel-Still had problems.

Flashed stock rom

My problems from all this accumulated somewhat and I can barely boot into fastboot. I get weird static screens and weird white noise sounds. It does not always let me boot into android and will get to the google logo 1 out of ten tries. Whenever I do press the power button from what I believe is completely shut-down I get static.

These is really unnerving and I have no clues what's what.
Note: I am using Faux123's kernels and his reset kernel.

Thanks a lot for any help!!!

If you want the easy way out, you might want to try this. It's Wug's toolkit from XDA and it's almost fully automated. [Toolkit] Wug's Nexus Root Toolkit v1.5.5 [Updated 11/04/12] - xda-developers

Use the "back to stock" option. It will flash the stock image and unroot the device. The toolkit right now only downloads 4.1.1 but you can download the full 4.1.2 image from Google. You will need the MD5 Checksum number to continue but it will be posted on the Google page. It will unroot your N7 but it's better than a brick. You can then re-root with the toolkit or however else you do it.

If you want 4.1.2, it will be the "Nakasi"; just download it to your PC and you can select it during the process.

I tried to return to stock on my own and it went from bad to worse. Even though many people give flak for using toolkits, this saved the day for me..

Of course.. disclaimer, this is all still done at your own risk.
