Introduction
Thanks to my very generous donors I managed to buy an A5 2016 cheap on eBay and have ported our new device tree and kernel to this device.
This is far more stable and much snappier than the previous releases available as the new kernel/tree is much quicker.
Features and ImprovementsStable
Fast​What worksCalls, SMS, Mobile Data
Camera
NFC
WiFi
Bluetooth
Torch
Fingerprint scanner
SELinux Enforcing​What doesn't workSome 2D animation stuttering (WIP)
Occasional Camera HAL crashes (same HAL bugs as A3)Fixed in 27/05/2019 release
VoLTE (will never work on LOS)
You tell me​Installation
Download the latest LOS build and transfer it to your phone
Install the latest TWRP (Available Here)
Make a full backup (just in case something goes wrong)
Do a full wipe (Cache, Dalvik Cache, Data, System)
Install LOS
If you are installing GApps do it at the same time (preferably in the same install queue)
Install Magisk if you want root
And finally boot, the first boot can take several minutes as it optimises all the apps

Build Instructions
1. Setup a LineageOS build environment based on one of the supported LineageOS 15.1 devices: https://wiki.lineageos.org/index.html
Note: All commands below are executed from the LineageOS root directory
2. Initialise the LineageOS repositories
repo init -u git://github.com/LineageOS/android.git -b lineage-15.1
3. Sync the repos (can take a log time, around 30GB of downloads)
repo sync
4. Create the .repo/local_manifests directory and add the a5xelte manifest (attached)
mkdir .repo/local_manifests/
cp ~/Downloads/a3xelte.xml .repo/local_manifests/
5. Sync our device trees in
repo sync
6. Setup the build environment
source build/envsetup.sh
7. Finally start the build:
brunch lineage_a5xelte-userdebug
To pull in new changes it is usually only necessary to repeat steps 5 - 7.

1. I have seen this too, it is odd as we use the same software stack on the A3 and S5NEO and get really smooth composer/animation performance. I am looking in to this.
2. Are you able to copy out the /proc/last_kmsg file and send it to me via pm? You will need root. I have seen a random kernel crash related to audio that I am looking in to, it may be the same issue but the last_kmsg will help.
There are no real "kernel optimisations" as such, our kernel started as the stock A510F kernel which we updated for Oreo. We used this as our base for the A3 and S5NEO as it was the latest kernel with the most frequent updates. I just recently divided it might be nice to port this to it's original device
With regards to Pie, I will be making Pie builds in the near future. I just wanted to get a stable and tested Oreo ROM before I add the Pie patches.

Hi bro i got one more time random reboot in the lockscreen,sorry bro i cant send logcat or /proc/last_kmsg because i am restarted my phone .I guess random reboot reason is not wifi . If i get one more time, i will send you bro also maybe u can know me ,we are speaked discord many time . Last one ui is fully smooth but only notification bar animations do that.

The crash I saw occurred just after I unlocked it via fingerprint, but the logs revealed that it was not fingerprint related but was related to the audio driver.
The /proc/last_kmsg file is persistent after a reboot, that is why I have asked for it. It may be the crash I have seen but I need more logs to confirm exactly where the issue occurs.
Regards,
Danny

Uploading a new release, changes:
device tree: pulled in the correct power_profile.xml from stock (fixes reported battery size)
kernel: Fixed a NULL ptr dereference in the sound DMA code that causes a system reboot

---

Installed the rom, bugs which i found at this moment: (I'm sorry for my bad English, I from Poland)
1. Laggy notification center, and lock screen (but not always)
2. MTP not always work
3. Audio causing reboots (on stock music player less often than on liked by me "Retro Music Player")
And i not found a option to change lock screen wallpaper.
Rom is very fast - faster than other builds of lineage 15.1 and 16 for this phone

---

idk why, i try to clean install, and same too.
but this rom so smooth and really fast.
no lag for pubg ?
thank you so much sir.
