https://github.com/8890q/ for LineageOS 19.1/18.1 device tree, kernel, hardware support, blobs

https://xdaforums.com/t/treble-aosp-g930x-g935x-project_pizza-trebleport-v2-0.3956076/ for libsensor blobs

https://github.com/osm0sis/ for anykernel, used for the twrp patching zip

Special thanks​

https://github.com/ExpressLuke for hero2lte testing

https://github.com/00p513-dev for suggesting using squashfs for vendor partition, making it possible to skip partition table modding

https://github.com/phhusson for looking into the double tap to wake issues with phh GSI

https://github.com/ivanmeler for prompting me to look into lpm again, now it is migrated into /vendor

Notes:​

I do not own a hero2lte(edge)

I'll mostly work on this only during weekends/holidays

and on that note the hero2lte build is not tested by myself

for vndk30 based vendor (LineageOS 18.1), use with android 11 and up GSIs

for vndk32 based vendor (LineageOS 19.1), use with android 12L and up GSIs

2022-06-12 the CACHE partition is now used as vendor, the HIDDEN patition is now used as cache, no more partition table mods required

Updates:​

2023-02-23

added store_mode.zip flashable that uses "/sys/class/power_supply/battery/store_mode" and "/sys/module/sec_battery/parameters/store_mode_max" interfaces for limiting battery charging

flash to limit battery charging to 70%, flash again to disable charging limit​

​

after flashing, charging limit can be adjusted at "/system/etc/init/8890_store_mode.rc" by changing "70" on the line "service enable_store_mode /system/bin/8890_store_mode 1 70" to other percentage values​

2023-02-15

include libaptX_encoder.so in patchers

adding patches to support phh android 13 GSIs:

includes lineage lmkd, LineageOS/android_system_memory_lmkd@be8c793 seems required for lmkd to work on this kernel​

​

fix bluetooth audio by disabling sysbta (generic in-system bluetooth audio implementation), see phhusson/treble_experimentations#2519​

​

disable full disk encryption and quota when booting android 13, 8890q/android_device_samsung_universal8890-common@3cbcf97 8890q/android_device_samsung_universal8890-common@f536d3f ; FDE still works when using android 12 GSIs​

​

disable healthd offline charging service, conflicts with lpm​

2022-10-04

update gps blobs from https://github.com/8890q/proprietary_vendor_samsung/commit/698ddd9acd7bdca78ecea93e06fd78a0d9dbc407

2022-09-05

adding keystore fixes to a12_patcher.zip:

https://github.com/LineageOS/android_system_security/commit/356c125115c0a9b9f9670b5b86b6e291c5ec5404

https://github.com/8890q/patches/commit/9a322b4e71ca784d4a2f71494d1ef0e52f835efe

which fixes keystore apps and device encryption on Google 12L GSI, might also fix some keystore apps issues on phh GSI

2022-07-10

moved lpm to vendor partition

2022-06-26

rebased vndk32 on 2022-06-24 build from ivan

new smaller vendor flasher, flashes only boot and vendor

2022-06-24

lpm_installer.zip should work with Phh and Andy Yan GSIs better now

2022-06-18

vndk30 prop changes, might help booting exotic GSIs

2022-06-13

android 12 data usage meter now works with a12_patcher.zip

2022-06-12

fixed neural network api hal

fixed fingerprint sensor

switched vendor image to squashfs, no CreateVendor required anymore with it's small size

new twrp patcher zip, should no longer cause "twrp is stuck after flashing CreateVendor"

bigger GSIs should fit better now with the original ~4.5GB SYSTEM partition; device native roms can be used without RevertVendor

2022-05-31

fixed wifi tethering

vndk32: rebased on 2022-05-26 12L build from ivan

phh_wifitethering_patcher.zip for wifi hotspot on phh GSIs

2022-05-26

added vndk32 based release

lpm_installer.zip for offline charging

fixed keystore errors on android 12 GSIs, lock screens work now

2022-02-15

rebased on February build from 8890q

January android updates

2021-12-16

install libaudioroute into /vendor/lib

December android updates

2021-12-10

move properties to /vendor

Tested GSIs​

vndk30

https://github.com/phhusson/treble_experimentations/releases/tag/v413 (vanilla/bvS)

https://developer.android.com/topic/generic-system-image/releases (android 12 gsi, with a12_patch.zip flashed after)

vndk32

https://github.com/phhusson/treble_experimentations/releases/tag/v413 (vanilla/bvS)

https://developer.android.com/topic/generic-system-image/releases (android 12 gsi, with a12_patch.zip flashed after)

important: system as root builds, you'd want ab build GSIs

Known issues:​

some GSIs like official google GSIs lacks the /efs mount point, it has to be added manually or it will boot loop at samsung logo failing to mount /efs

some android 12 GSIs does not boot due to the lack of ebpf on the 3.18 kernel, android 12 GSIs needs to have patched bpfloader and netd, see below

https://github.com/8890q/patches

https://github.com/phhusson/platform_system_bpf/commit/c81966c23d79241458ebf874cfa8662f44705549

https://github.com/phhusson/platform_system_netd/commit/3a6efa1ff3717a613d1ba4a0eff5e751262d1074

data usage stays at 0 MB used on android 12 GSIs, because ebpf is used for metering

a12_patcher.zip attempts to fix the above issues by creating /system_root/efs and importing bpfloader+netd from https://github.com/8890q/patches

a11_patcher.zip creates /system_root/efs if required

usb adb does not work on android 12 GSIs

a legacy implementation of usb adb is required for this kernel, see https://review.lineageos.org/c/LineageOS/android_packages_modules_adb/+/326385

as a workaround, disable usb adb and use wifi adb

Wifi tethering does not work on phh GSIs <= 414

https://github.com/phhusson/vendor_hardware_overlay/tree/pie/Tethering conflicts with our Tethering overlay

flash phh_wifitethering_patcher.zip after installing phh GSIs

Alarm clock not working on aosp GSI

it should be fixed on phh 414 and up, it is not a vendor issue. If you are using an older aosp GSI, flash deskclock_powersaving.zip to fix that. See https://github.com/LineageOS/androi...mmit/8dd096c4cfb647960be1695a57246727878b8c8d

Google android 13 GSIs do not work

post-build patching got more involved in android 13 since on-java patches are now required, stick with phh/treble droid GSIs which already include build time patches for bpf-less kernel support

Disk encryption does not work on android 13 GSIs

full disk encryption is removed in android 13, file based encryption not available currently https://github.com/8890q/android_de...mmit/3cbcf972465419c18bf4850d26320896df465b18

Installation​

If you are using the old partition table mod zip heroxlte_CreateVendor_2.0.zip from older versions, first flash heroxlte_RevertVendor_2.0.zip, or revert your partition table other ways such as odin. Skip this step if you have never touched your partition table

Install twrp-3.6.2_9-0 from https://eu.dl.twrp.me/herolte/ (s7) or https://eu.dl.twrp.me/hero2lte/ (s7 edge), as of rignt now newest(twrp-3.7.0_9-0) is too big for flashing

Flash twrp_patcher.zip to enable system.img flashing, it'll reboot to recovery once it's done, tested on 3.6.2_9-0 but newer versions should work unless recovery.fstab changes

Flash vndk32 for android 12.1(api level 32) and android 13.0(api level 33) GSIs, flash vndk30 for android 11(api level 30) and 12(api level 31) GSIs, herolte for s7 and hero2lte for s7edge

Flash the system.img of your choice

If you are using phh GSI version <= 414, flash phh_wifitethering_patcher.zip

If you are using phh GSI version <= 414, flash phh_dt2w_patcher.zip to fix double tap to wake

If you are using phh GSI version <= 413 or pure aosp, flash deskclock_powersaving.zip to fix alarm clock

If you are using an android 12/12L GSI, flash a12_patcher.zip

If you are using an android 11 GSI, flash a11_patcher.zip

If you are using a phh/treble droid android 13 GSI, flash phh_aosp13_patcher.zip

Updating vendor​

Flash vndk32 for android 12.1(api level 32) and android 13.0(api level 33) GSIs, flash vndk30 for android 11(api level 30) and 12(api level 31) GSIs, herolte for s7 and hero2lte for s7edge

Undo twrp_patcher.zip and revert to device native roms​

This is not required for using device native roms, however OTA updates might require this

Flash the newest twrp again

Format cache using wipe -> select cache -> repair or change file system -> change file system -> ext4

Flash a device native rom

Building​

lineage_build_herolte_vendor_part, lineage_build_hero2lte_vendor_part, lineage_build_herolte_vendor_part_18.1 and lineage_build_hero2lte_vendor_part_18.1 builds lineageos along with treble vendor using https://github.com/lineageos4microg/docker-lineage-cicd

you'll need ~15GB of free ram, ~300GB free disk space and podman

# create directories

mkdir src

mkdir zips

mkdir logs

mkdir ccache

# builds lineage 19.1 along with vndk32 for herolte (s7 flat exynos)

bash lineage_build_herolte_vendor_part
