[G4 Android Development] steadfasterX:
OK guys. This update is BIG.

Not only bc it includes a lot of stuff but also the complete way how I build changed in the background.

I have done dozens of tests to ensure it will not do any bad but well.. there is a always a chance right..

Unifying our device tree makes it much easier to maintain and to add other not-yet added models - while it comes with the risk something goes wrong when it comes to blobs.

As this is the very first round of my unified device tree I would highly recommend doing the following (I have done that in my manual builds but you get it from jenkins - so there is a tiny little chance of bad luck .. ):

Pre-Cautions | Flashing instructions

Recommended: Backup (system, userdata in TWRP, your internal storage which contains your photos etc elsewhere)

Required: Do a "REGULAR CLEAN FLASH" (see bottom of this post)

Flash LOS - DO

NOT

choose to reboot afterwards - stay in TWRP.

TWRP menu: "Mount" --> choose "System"

From a terminal execute:

adb shell md5sum /system/etc/firmware/venus.mbn

Compare the value (last 4 characters is fully enough) with these:

If you flash:

h815, f500, h818, h819 it should be: ebc5d32c651bf061787e82258cf78a3c

h810, h811, h812, ls991, us991, vs986 it should be: 78e5cf520d0de4a413ef1cfa7bbbe713

WARNING: If that checksum is NOT as it should be: DO NOT PANIC! simply FLASH the PREVIOUS LOS version BEFORE booting!

. This will ensure you will not blow a fuse.

While the above test should be considered safe: If you are unsure about this procedure:

WAIT before flashing

until someone (or I) had done the above quick test from the builds jenkins is providing at my leech server.

Whenever an error occurs while flashing in TWRP (e.g "E1001: Failed to update system image.Updater process ended with ERROR: 7")

or if the above checksum does not match:

provide the recovery.log (FAQ #4 A)!!

... then flash the previous LOS version to get back to life.

New builds are cooking...

build errors can happen .. so it might take longer until everything completes (as I can fix build issues tomorrow first if any)

In progress (in that order):

Live - View: https://lets.binbash.it:8800/job/LG-G4/job/LOS-16.0/job/Build all LGE-G4 models/workflow-stage/

H810

Done:

H815 (a re-build to patch the gapps issue* is required - until then use the workaround as described)

H811 (a re-build to patch the gapps issue* is required - until then use the workaround as described)

H815 UsU (a re-build to patch the gapps issue* is required - until then use the workaround as described)

VS986

H812

Noteworthy Changes:

All models moved from dedicated trees to an unified device tree. While doing that I fixed/added fingerprints, missing infos and more.

Oh yea and ALL (relevant) models have been added (while I do not build all of them atm .. but now it will be easy to build if someone (or I) wants to).

If you have one of these models: ls911, f500, us991 and want to have a model specific ROM release: let me know the

model

and a "+1 to build" notice as a post here. I will decide to add them to the list then. A current full run takes approx ~ 10 hours so who cares :p

(u may noticed: I exclude h819 here as no one use that.. it even not had received official MM so.. I guess no interest for that anyways?!)

Voice mic sensitivity increased when on speaker

tons(!) of kernel fixes & optimizations thx to [MENTION=5461026]kessaras[/MENTION] . That includes e.g the graphic driver as well (thats why I keep staying with opengl and not switched to skiagl as I first planned to)

Selinux =

Enforced

. I have tested encryption here as well which goes fine (after adding all req policies obviously)

If you encounter issues try this first:

adb shell
su
(or adb root when enabled)
setenforce permissive

Try again and if the issue is gone when in permissive mode: provide me a logcat as described here

Selinux = Enforced policies have been added and tested for:

- LOS root-addon downloaded from today (16.0, arm64 ofc)

- open_gapps-arm64-9.0-nano-20190709

- even when I do not support it: Magisk 19.3

QCRIL db is now writable. Once your phone boots / RIL starts you receive an updated collection of emergency numbers (i.e. 911 for the US etc). Until now these updates went to hell as the DB is readonly (as it sits in the system partition). I fixed that in a way that it starts now with a base DB and will create a writable copy to /data which then can get updated.

One of the most noteworthy changes is ofc: RIL. It is

fixed

now and .. tbh .. it is not 100% clear why :D We fixed and implemented so many things in that time range that it is impossible to say what exactly fixed it. but who cares? it does not crash anymore and that solves a lot of lagging and issues we had.

Since ages all LOS builds should pass SafetyNet (I tested for h815 already) but if not - let me know and share your model and a logcat while trying to pass safetynet as it turns out it was a "should". The testing on that was a bit tricky as when you install magisk it will pass it perfectly (not surprisingly) but google play is still showing as certified even when magisk has been uninstalled completely afterwards (which was the way I tested). Another thing is that the device certification check does not happen immediately when you open the play store - it can take a minute or more (and it happens silently). in the meanwhile everything looks just nice (all apps are shown). Last but not least testing requires a full cleared play store. Long story short: a fix comes asap

PLATFORM_SECURITY_PATCH: 2019-07-05

and others ... and all the details

IMPORTANT:

Taking a backup before is recommended -

always

A "REGULAR CLEAN FLASH" is

REQUIRED

with this build (as several things changed in system partition).

See the FAQ of this thread how to do a "regular clean flash": https://xdaforums.com/g4/development/rom-lineageos-16-0-t3929082/post79502871

Keep in mind that almost all pie ROM's sharing the same common device tree (or main parts of it), same model device trees and for sure the same kernel - so you can enjoy most fixes for any pie ROM available..

The above fixes are brought to you by the Suicide Squirrel Team :victory:

ok enough of words, just

one

more thing:

FLASH and ENJOY that ultra stable, fast, smooth and best pie build for LOS -

ever

:)
