Nexus 7 car install with debug / otg charge / volume buttons and more topic

After reading a lot of nexus 7 car builds, I attempted it myself too.
2 months have past now and i've been testing some stuff.
I made preperations to install the nexus 7 and decided a permanent installment of the tablet.
I' d like to share my experiences in this post. :)
i'll update as i progress.

Here are 2 data scheme' s I have made.



I just hope the debug switch in combination with the otg switch will work.
It's 2:45 am here now. so sleepy time first. I'll continue this post tomorrow :)

[Q] Bad Screen: Need UVUAMDL friendly kernel with USB debug turned on. topic

Noob here.

Screen stopped working on my SGH-M919, and I want to return to stock condition with zero flash count.

First thing I did was flash to UVUAMDL stock. (I never installed newer bootloader) Plan was to root and use screen mirror app which uses USB debug mode to root, install and run triangle away, then reflash to stock.

Didn't realize this would turn USB debugiung off, and I can't see what I'm doing to turn it back on.

Seems easiest way to turn it back on is to flash a custom kernel that pins it on. preferably via Odin or heimdall rather than a custom recovery

Also: It's hard to muse CWM recovery without any screen cues. Does anyone know where I can find a description of the meny so I can figure out how many times to hit each key?

I did search extensively (for days, actually) but now I'm stuck.

Any other suggestions would be gratefully appreciated.

Thanks.
