reboot test and report feeds back
I'm running 3.1.10 MM kernel. Do I need to flash twrp k3.4 as indicated in Ziyan thread? It seems some are having problems to boot to twrp recovery or connect to the pc to flash after trying to upgrade to Android N. I dont mind running into bootloops as long as I am able to recover my grouper from the backup or able to reinstall from twrp or pc. Thanks.

Go to settings - Apps - Google Play Services and give it all permissions it needs. That will fix the problem

I experience the same issue as well, with Google Play trying to install any application (eg Gmail) and be left stale at "Installing" even though both Google Play and Google Play Services have all the permissions enabled.

I also wiped Dalvik a couple of times and the relevant google account data.. to no effect..

I had the same issue before as well...as I do not recall how I fixed it as it has been so long. Do you have the latest Gapps version? I think my Google play version was out dated.

Hello everybody! I installed 6.0.1_r46-Grouper.zip + BETA-SuperSU-v2.71-20160331103524.zip + ParrotMod_Grouper_Universal_2016-08-31_10.36.37.zip, but file /sys/block/mmcblk0/queue/read_ahead_kb contains "2048" :(
Later I update SuperSu from Google Play to v2.78, but there no effect :(
Can someone provide a working solution how install ParrotMod for this ROM?

I have the sleep of death issue with this one too. I have tried every rom after android 5.0.1 and none resolved this issue. Same with this one.

A small suggestion - please change device name in Settings -> About -> Model from "Nexus7 2012 WIFI" to vanilla value (something like "Nexus 7", I do not remember that there was).
It is necessary because Google Play not detect device correctly:

I installed rom ([ROM] 6.0 Android MarshMallow Pure AOSP for Google Nexus 7 2012 WIFI by vocoderism) on nexus 7 grouper along with gapps, supersu. It works ok and BT is working which i could connect my BT keyboard to it. However, after I install parrotmod (ParrotMod_Grouper_Universal_2016-10-14_19.33.56.zip). The BT stop working and pop up "Unfortunately, Bluetooth Share had stopped".

May I know where I can go from here to fix the BT so that it can be use?
Thanks in advance.
