[ROM][7.1.2_r8][UNOFFICIAL] LineageOS 14.1 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 or 3.1.0.
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.
If you use ext4, run fstrim.
There are ways to automate this, but I just run this app after each ROM upgrade, plus roughly once a week, after large batches of app updates from Play Store, or whenever my tablet starts to feel sluggish.

There are plenty of guides to building CM. Those guides are still relevant with the possible exceptions of their URLs. Assuming you have read enough such guides to have the general idea of how to build a ROM from source, here is one way you can set up your source tree to mimic mine.
In a clean directory, perhaps ~/android/lineageos-14.1/ :
Code:
repo init -u git://github.com/LineageOS/android.git -b cm-14.1
git clone https://github.com/aperomsik/lineageos_local_manifests.git .repo/local_manifests -b cm-14.1
repo sync -c
. build/envsetup.sh
brunch grouper
fantastic Job! We now have a new ROM

Recent version of repo doesn't seem to explicitly support '-c' parameter any more to reduce the download size (mine have been around 30GB). Thanks for these instructions; still, I would like to know how you integrated the required changes for 14.1 grouper.

Thank you aaopt for keeping our old Nexus 7 alive !
Can someone tell me the perfect settings for Kernel Adiutor to get the maximum performances ? Even if the battery life is shorten.
Thanx in advance

Just took a look at those. I have been using TheMuppets at github for the proprietary components, having needed to patch the nvidia components due to an old GNU-ism (gcc extension that was eventually formalised).
Saw that you got the broadcom et al components from your "ads" git repo and wanted to know if there was any reason not to use TheMuppets (or if, indeed, you sourced them from there and modified them), that I can learn from.
Thanks again.

Can confirm that this works - now I just need to find the magic in the code. Also, how did kernel/timeconst.pl not need to be replaced with timeconst.bc and kernel/Makefile not need to be amended to use bc instead of perl? I was getting a compile error because of this in the grouper kernel tree.

The "ads" git repos referenced in my manifests are AndDiSa's. My repos are labelled "aaopt".
As stated in OP my goal with this ROM is to continue GtrCraft's CM13 work now that he has moved on to other devices. He had been following AndDiSa's proprietary components from AOSP so I just continued that way. In fact I took it a step further by using AndDiSa's kernel directly, not (yet?) seeing a clear reason to maintain my own. I just want to do the minimum amount of work needed to keep somewhat up to date with upstream LineageOS and take advantage of AndDiSa's device-specific performance improvements from the AOSP side.

Oops. I got that wrong. Anyway, thanks for your work and I learned a few things from it.
Just flashed it, will see how it goes.
For now when the only bug
When i take picture with camera, it mirrors it and makes it look pixelish
Great! Happy to see our grouper still updated, thanks

Hey there! Will there be a ROM for Tilapia? I'd be nice to try it on it. I'm not a programmer but as I noticed building for Grouper and Tilapia is just a little different.
I think You can just flash the grouper recovery and flash the ROM.
From one day of full usage:
- The charging is a bit slow, i don't know if it's a big battery or the power flow is low
- There is lagging, like the ROM isn't optimized yet, slowdowns, applications are usually giving me stopped working etc...
- The camera bug i mentioned above, when u take picture it looks pixelated
I'll do more reviews like this if the updates keep coming
Cannot use the video option in the camera app.
The camera app force closes.

Here is a build I am testing, in which all I did was sync sources with upstream. It feels somewhat less laggy to me... not sure if it is due to Lineage changes, 7.1.1_r9, or the fact that I used newer opengapps.
Camera issue is interesting -- I have a shot in my camera folder from 11-29 which looks better. Current shots claim to have the same resolution but file size is much smaller, which suggests the wrong jpeg quality setting was used. Something to dig for.
Regarding charging, are you saying it charges more slowly with this ROM than with others? Charging speed varies widely for me but recently it hasn't been that bad. If your hardware is behaving the expected charging time from nearly empty is supposed to be 3-4 hours. Over time the connector gets loose and then charging can take much longer. There are plenty of charging-related threads around here including some which say to replace the USB port and one which says take out the existing port and put it back in. Tried that on the worst of my family's tablets and it helped for a day or so but then went back to old slow charging speed.

Hello,
I recently compiled CyanogenMod 14.1 for my Android device using the official sources and want to compile Omni 7.1 for the same device and use the device tree and kernel from the official CM sources because there's no device tree for Omni. Is there a way to "convert" the CM device tree to work with the Omni sources? My exact problem is the compiler doesn't know my device so I can't run something like "brunch [device]" or "make [device]", although I already downloaded all device-specific repositories to the same subdirectory as I'd do it on CM.
Thanks in advance,
Oebbler

You have to go to your android_device_manufacturer_yourphonecodename repo and rename cm.mk to omni_codename.mk, open it and change cm_codename to omni_codename.
You have also to rename cm.dependencies to omni.dependencies, but the repos included in that file may not be in omnirom source, so you would need to manually sync those repos in your android sorce tree.
You might have to make other minor changes, take a look at the rest of code in that repo.
For further info: https://docs.omnirom.org/Porting_Omni_To_Your_Device
Thank you, but I think I won't succeed in building Omni for my device because I always get strange errors.
Probs will get annoyed, cmsdk, cmhw, and cm encryption are significantly annoying. Also they moved their build dir, generally include useless common subtrees, and named dtbtool with CM suffix. Their build tree might be the most significant hindrance to unified building on Android, not only for the many unnecessary additions and dependencies they have for devices, but also they generally lack a community presence to answer or respond to users, so a lot of us get stuck with cleaning up their mess.
Notice how TWRP has a community presence here and are helpful. I'm not hating on cm, they have been doing this longer than most of us, but for ease id recommend using your rom choices tree.
Also the immensely significant annoyance of having to track devicesettings and the unwillingnes to nuke cmactions, combine it with cmsdk, or at least remove it's dependency in most trees is almost certainly going to cause you errors.

I'm currently running official LOS14.1 but have been wanting to switch for a while. One thing that bothers me is the lack of OMS (Substratum support). AFAIK this was implemented officially in LOS15, for which there is an unofficial build, but I also want to have Sultan's tweaks (even willing to compromise on Nougat instead of Oreo because the highest version of LOS that Sultan modified is Nougat).
Sultan's LOS14.1 (which I probably will install even without OMS for now just because it's better than official 14.1) looks awesome but it lacks OMS, although someone managed to build it with OMS. I tried PMing this person and asking for help but didn't get an answer yet, and I don't have any experience in building Android (I do know my way around Linux).
So my question is, how do I go about building Sultan's LOS14.1 with OMS?
In here there are a few methods for merging the necessary changes, all of which I don't understand how to do in the context of Sultan's LOS. He (Sultan) only links to the source for his bacon kernel and a local_manifest.xml file, which I don't know how to use. I think there are some files missing but I don't know where I should get them from.
Can someone please point me in the right direction?
1. Fork sultan's patcher repo
2. Get the OMS patches from LineageOMS (e.g. frameworks/base: use command "git format patch HEAD~52" to create all of the patches)
3. Move the OMS patches into patcher (don't forget to add related lines to patcher.sh and unpatcher.sh)
4. Replace sultan's patcher repo with your one and add substratum/interfacer to the local_manifest.xml
5. Sync lineage 14.1 source code
6. Build
Hello all,
When building without any changes to the local manifests, the build errors out. These are partly resolved by adding the samsung and ti vendors from the muppets, but then new errors pop up. If anyone has managed to build this image could you post the manifest?
Thanks in advance!
Late but: how about posting the error? Sources on LineageOS git should work fine to compile.
On Ubuntu 18 you might run into an error depending on flex which can be solved by Cherry-Picking https://review.lineageos.org/c/LineageOS/android_prebuilts_misc/+/229452
I want to build my unofficial build for my phone, HTC Desire 816. But I have a limited data plan, and I worried I will running out of my data by downloading a huge source code with unnecessary files for other architectures, phones etc. And I'm just need the ARM and important files.
Also I got these repos from Tarkzim's forum at LineageOS unofficial for HTC Desire 816:
Device tree
Kernel
Vendor
Well, I didn't have any experience at Android development. So maybe can someone give me a guide too?
I'm just know the preparations on the documentation and it's ready, but the steps are confusing for me.
Or maybe if peoples are have their time maybe can someone make the official build?
Maybe it such out of BlissROMs, but I really want to Blissify my phone. Because LineageOS are too plain, no good features like smart charging etc. It just looks a normal Android build from AOSP source.
