Lemme hijack this conversation at this point.

We (and by we, I mean, [MENTION=5689422]faizauthar12[/MENTION], myself, and (hopefully) [MENTION=5790433]Rohan purohit[/MENTION] too (who's been afk for quite a while now)) want to use the latest blobs/firmware from the vendor because they are usually up-to-date with *cough* fixes *cough* (and we don't have to deal with "omg your ROM doesn't boot for me, I'm on firmware 8.x").

My CAF kernel has all the necessary changes to get the device up and running with 8.x firmware. The current sources are based on stock changes rebased onto (an M tag?) by fire855, with mainline upstream patches merged in until 3.10.105 (?), and a bunch of other fixes/optimizations from a _lot_ of different sources. It all works just perfectly and Rohan doesn't want to lose all of that hard work and prefers a minimal patch that _just_ gets the kernel booted with 8.x (this is comparatively easy to do).

I'm kinda against it (the mainline upstream patches merging, and random fixes/optimizations); not because idgaf about security/issues, but because of regressions that creep in because of them. This is why I haven't made that "minimal patch" yet. It should be fairly easy to fork my source, upstream to 3.10.105, add back all the cherry-picks (which, again, I won't be doing). The only difference with current source would be that the device bringup code will be a lot cleaner.

What the device maintainers choose to do is their option, but a common ground is to be reached.

So, what would I like by the time N gets official?

(wait for 8.2 global stable) update all blobs to latest firmware

ROM is fully compatible with 8.x firmware

Vulkan blobs ( N-specific )

This would help with? MultiROM ¯\_(ツ)_/¯

P.S. Oh, and the wcnss crash thing? Faiz says that the issue isn't there in Marshmallow. So, this may be N-specific. Even kernel/huawei-8916 face this, and reverted back prima which supposedly fixed it. So, a _fix_ will probably be merged in soon. (this is only for the ROMs from Faiz's AFH which have my kernel).

Update3: Have installed Supersu and gapps.

Gapps has a problem and I'm trying to resolve it via the hosts edit/overwrite.

Supersu won't give my apps(helium) permission and supersu binary is missing from the menu.

I have enabled root for apps and adb in developer options btw.

No apps displayed in "Manage root Access"

Update4:Factory reset then downloaded gapps arm64 pico from lineage os' official repo.

Installed SR3-SuperSU-v2.79-SR3-20170114223742.zip

Supersu and google play now works.

my only salt is helium still not working(doesn't ask for supersu and connecting to desktop shows helium activated but nothing happens on android.)

Well I can just reinstall those apps and input the configurations again.

First of all thanks for this awsome rom

It might sound a bit selfish but when you said its your last lineage os build did you mean its last buid for lineage os from your side or its your last build for mi4i itself ,i mean are you also leaving mi4i development ?

We need developers here as xiaomi has turned its back towards mi4i and its only you all developers at xda that our beloved mi4i has seen android 7

So it would be nice if you continue developing for this phone rest it is entirely your choice

[Fire TV Q&A, Help & Troubleshooting] Y314K:
You would need a fully unlocked bootloader & although most AFTV devices have been rooted at different FW version. Only some first year FTV1's with early FW where capable of being Fully bootloader unlocked. I am lucky enough to own 4 of them.

There have been multiple new methods to root AFTV(S)'s. But no new methods of unlocking their bootloaders. So for now changing the OS on AFTV(S)'s is not going to happen.
[Fire TV Q&A, Help & Troubleshooting] Y314K:

I'm having trouble finding tutorials and wondered if you could tell me if it is possible and if you know of any resources of tutorials? What do you run on your FTV 1 boxes? Any other suggestions for tinkering?
[Fire TV Q&A, Help & Troubleshooting] Y314K:
http://xdaforums.com/fire-tv/general/project-aftv2atv-t3489239/

The above is still the closest option so far. There where a couple of projects a few years ago which you can find here on XDA where developers started to make a Cyanogen 12 & other FW options for FTV1's with unlocked bootloader. But development faded once only a small percentage of FTV1's where capable of having their bootloaders unlocked. And none of the other devices have that capability.

Most mods now are just launcher changes & Amazon service deactivation for a leaner FireOS. But every option still has FireOS as it's base. The AFTV2ATV project does the most changes over all.

You can find the old projects under both development sections.
