[ROM][7.1][UNOFFICIAL] CM14.1 for Nexus 7 2012 (grouper)

*** Disclamer

By downloading and installing this ROM you agree that you do so at
your own risk, and that you understand that it probably voids your
warranty. (But does anyone still have an active warranty on this 2012
device?)


Introduction

@AndDiSa's AOSP 7 builds look pretty nice, but I needed something that seamlessly upgrades from CM13. @GtrCraft who provided our CM13 builds has moved on to other devices, so we need a new CM maintainer. I may not be the right person for that job... but I can at least share the build I made for myself. Perhaps someone will be motivated to join the fun or even take over.

Installation instructions

• 
  Back up your data and previous ROM with TWRP 3.0.2.
• Download from link below.
• Wipe system, cache, dalvik.
• Also wipe data unless you are coming from CM13.
• Install the ROM.
• Optionally add opengapps-pico.
  
  With default settings it will give an error about insufficient space. To avoid that, first copy this gapps-config-grouper.txt file, perhaps edit it to your taste (instructions here), then copy to the device in the same directory as the opengapps zip. The opengapps updater-script will look for it there when you install opengapps.​
• Reboot.
  
  WAIT for system to settle before you decide it is slow. Some of the app optimization which used to happen during initial boot now seems to happen in the background. When it's finished, responsiveness will improve.​

seems to be pretty stable so far but i cant get pico gapps to install even after installing the rom with the gapps-config.

 

[eNVy]

There is a 3.4 kernel build for grouper which was helpful for cm13. Can you incorporate that into your build ?

 

[abhifx]

why is this not even on development thread?
is this based on anddisa's device,vendor trees? cuz that build is super fast. i am downloading anyway.

Sorry about that. I meant to say .gapps-config goes with the gapps zip, not with the ROM. Corrected, and also edited for clarity. If it still doesn't work for you, look at the log file it generates in the same folder as the zip, and make sure it says it read your config file.

I had originally put it in development, but it took me too long to fill in the devdb new project page... after it made me reload the page and reenter some things, apparently I wound up in general by mistake.

Yes, when I saw how fast @AndDiSa's AOSP 7 ROM was, I had to try a CM14 build. I'm using his kernel and vendor trees, and many of his recent device tree commits cherry-picked into a fork of @GtrCraft's CM13 device tree.

 

[abhifx]

Requested mods to move this to development section.

Also can't install gapps with the given script. Anyone up for new gapps zip?

Please pastebin your resulting open_gapps_log.txt, and send me the link . You should find the log file on the device in the directory where you had put the gapps zip and config files. For comparison, mine is here.

will post it in the evening, i dont think gapps is picking up the config file, should the config file go inside the zip file? i am just pasting it outside the zip file.

Frankly the ROM is working fine, however i have yet to lock gps and test it which is my main usage.
After seeing CM booting, i would love to see other derived ROMs (AICp, RR etc)
Maybe you can post a guide others may build it too (i dont have the disk space or the bandwidth to do it anyway)

Not in the zip file... Just alongside, in the same folder on the device (or usb stick if you install via OTG) where the Gapps zip is.

The config files name needs to be "gapps-config.txt" or ".gapps-config". I just tried the first option an gapps installed just fine!

I was having issues as well with the config file. I tried putting it in all kinds of places, but no dice.
I ended up using the Aroma Open Gapps package which worked great.

Haven't tried much on this ROM yet, but things feel snappy.

ah yes.. Aroma Gapps, which keeps on cancelling this huge package. oh well will try renaming the text file

ok this was even more weird, i copied the files in a separate directory (the config file was in txt format as suggested by @gothier) and this worked. earlier everything was in the root directory and nothing worked no matter was was the file extension, hidden or not.

 

[ruchern]

Thanks OP.

I've successfully installed the ROM on my Grouper device.

Also, I've installed Opengapps via CF's Flashfire app and it worked very well.

 

[Vladimir2k9]

Thank you for the rom.
I updated from CM13, install gapps with config , only rename it to ".gapps-config-grouper". I use all from USB drive via OTG for all my android devices.
All work fine.

 

[muromets]

Even in pico gapps package I had to exclude some apps so it could be installed. I've written in in gapps-config.txt this way:
GoogleTTS
calsync

A bug

When I pull down the notification/ quick settings, the device crashes and reverts to lock screen.

havent crashed on me yet.
@aaopt, it seems anddisa has a made some changes wherein camera is also working, maybe you can update the same for CM14.1?

 

[eNVy]

It doesnot happen always. Sometimes only.
