Since the stock rom doesn't have enough credit on this forum I'm submitting something I just did for myself in case anyone may find this useful - plus I'm adding some small customization to get the stock (mainly for ODEX version) better and more complete (starting with AOSP Browser and Flash Player support).
untouched stock ROM (odexed) taken directly from factory release ======> JWR66Y_grouper_stock_rom.zip (MD5: 10f87625214401afa6358c4f54564b4b)
ROM has been zipaligned, includes Busybox and init.d support and is rooted with SuperSU (you need to flash latest version to make it properly work on 4.3, get the package here http://download.chainfire.eu/supersu)
untouched stock KERNEL, in case you messed around with custom ones ======> JWR66Y_grouper_stock_kernel.zip (MD5: 4d5fb301d5e9ad450fa9de8acb33260f)
flashable zip to get AOSP Browser, Chrome Bookmark Sync and Genie Widget system apps that was removed by Google after 4.1 update ======> JWR66Y_missingSystemApps.zip (MD5: 0cc7588185573446fec6855b2c8ff36b) and JWR66Y_missingSystemApps_ODEX.zip (MD5: a85c7904cef794b353302a5875d7ddfe)
to make AOSP Browser work an apk named BrowserProviderProxy.apk, and respective .odex file, are removed by this cwm flashable zip under /system/app/ - if in any case you want to restore 'em here you go ======> JWR66Y_BrowserProviderProxy_ODEX.zip (MD5: 65b1d5d34f4822eaea1a3551ead66df9)
To download Flash Player
http://helpx.adobe.com/flash-player/...-versions.html search for Android and get the latest version
all archives are CWM flashable and tested by myself on my grouper (Nexus 7 Wi-Fi only) - check MD5 to assure any corruption before flashing and remember to clean Cache / Dalvik Cache from recovery AFTER applying any of them (especially for the ROM - Full Wipe needed if coming from a non-stock ROM, obviously) - you are warned.
Have fun
I'll try to keep the thread and OP updated as I can
