[Nexus 7 Android Development] bshiznit:
Stock 4.4.4 ROM (KTU849) for WiFi Nexus 7 (2012) Grouper​

Hi! This was created using @dsixda's kitchen (which I had to tweak for our device to get working). This was created by unpacking the latest KitKat OTA (KTU84P) and adding SuperSU/busybox...

Featuring:

Stock Android 4.4.4 KTU84P for Nexus 7 (2012)

4-way power menu! Thanks @cargobr151 - Need to get an update or figure out how to do this for now hopefully we can use GravityBox...

Google Experience Launcher (GEL) or Launcher2 (NOGEL) - you will be asked which to use on first boot. Don't be afraid to pick "always use" you can change the default launcher at any time in Settings --> Home - What happened to GEL? Just grab the Google Now Launcher from play store (no room on /system partition)... If coming from a prior version with GEL and not wiping data you should be fine.

Busybox v1.22.1 (needed for Trickster MOD)

SuperSU 2.00 with latest SU binary

Odexed & Deodexed

FOTAKill.apk in /system/app to prevent future OTA notifications (thanks for the suggestion)

DEODEX (DEODEX is here for themers and by request)

v1.6 - MEGA https://mega.nz/#!mZ1UUYjR!7tJG3tS7i6qDswEAEZ37J1fWjdOEenrKBs_XFwXKAxk

v1.6 - AFH https://www.androidfilehost.com/?fid=529152257862728316

NOTE DEODEX takes longer to boot than ODEX on FIRST boot after wiping dalvik!

CAN flash with no wipe over any of my 1.0/1.1/1.2/1.2.2/1.3/1.5/1.6 builds and stock JWR66Y/KRT16O/KRT16S/KOT49H/KTU84L/KTU84P

Coming soon:

ART? (Sorry still no ART in 4.4.4 for our device! No overhead on /system partition...)

Advanced Power Menu

GEL baked in (again)?

NOTES:

BACKUP using TWRP and Titanium - save those files off the device to a USB stick external HDD or whatnot! Not responsible for lost data!

Be sure you are at bootloader 4.23 or you could have slow charge issue http://xdaforums.com/showthread.php?t=2150251

ONLY TESTED USING TWRP 2.7.1.1/2.8.0.0 - NOTE there was a buggy release of 2.7.1.1 that doesn't play nice with the update-binary in my zip. If any issue flashing/booting first verify MD5 and then flash latest TWRP linked towards the bottom of this page http://techerrata.com/browse/twrp2/grouper. Should also flash fine under CWM but I personally prefer TWRP. A future update may move to the newer update-binary and updater-script files used in ROMs compiled from source like CM.

May need to unplug and replug USB cable to see Nexus 7 storage under My Computer! (or toggle MTP in Settings --> Storage --> Menu button in upper right)

If coming from STOCK 4.4/4.3 I can't think of a need to wipe - otherwise if issue or coming from another ROM (PA, CM, etc.) please do a data wipe and cache/dalvik-cache wipe

GApps are the stock ones that come with this tablet - no need to flash GApps.

You will see a BUNCH of updates when you sign into Google if you've wiped Data - results in an initial slowdown.

Before you ask, no ART doesn't appear to be working. I will make a new AOSP-based ROM for 4.4.4 for those wanting ART.

Thanks:
