AT&T USERS: since your bootloader is locked, you must be on the UCUAMDB or UCUAMDL bootloader.
VERIZON USERS: since your bootloader is locked, you must be on the VRUAMDK bootloader.​Do 'getprop ro.bootloader' in Terminal Emulator or through ADB shell to find out which bootloader you have.​
TWRP
You are REQUIRED to be using TWRP 3.2.3-0 or newer to be able to flash any Pie rom.
If your device does not have an updated relevant version then you can use the standard JFLTE version.
If you have a device with a locked but exploitable bootloader as above (AT&T + Verizon) then use the Loki-patched version.​
Latest recommended JDC TWRP Recovery v3.3.0-0 for JFLTE: HERE.
Official TWRP Recovery v3.2.3-0 for JFLTE Loki-patched by @mattgyver: HERE.
Other variants may require a different recovery. ​

The following are "best practice" recommendations for installation, you may be successful using your own routine.
1st install - " clean install "
Make a full nandroid backup <always backup!>.
** OPTIONAL Properly remove previous root solution (recommended - flash Magisk uninstaller and UnSU). **
Fully wipe device (At least system, cache, dalvik and data. Recommended - fully clean by wiping internal and external SD).
Make sure your partitions are formatted as EXT4. Do not use F2FS on pie.
Install Rom.
Install desired root solution. (recommended - Magisk).
Install Gapps (Pico or larger).
DO NOT Wipe cache and art / dalvik (rom is partially pre-deodexed).
Reboot.
Wait for 1st boot.
Enjoy.
2nd and subsequent installs - " dirty flash "
** OPTIONAL Uninstall all Substratum overlays ** .
Make a full nandroid backup <always backup!>.
Properly remove previous root solution (recommended - flash Magisk uninstaller and UnSU).
Wipe system, cache and art / dalvik (wiping system is ESSENTIAL for Magisk).
Install Rom.
Install desired root solution. (recommended - Magisk).
Install Gapps (Pico or larger).
DO NOT wipe cache and art / dalvik (rom is partially pre-deodexed).
Reboot.
Wait for app optimisation.
Enjoy.
While dirty flashing may be possible for some updates, be prepared that progress means you will occasionally need to clean install updates (usually when settings files are changed)!
Nandroid backups are your friend!​

Current issues
Release 07​
This rom is a nice combination of Aosp lightness and comprehensive customisation options.
This rom should get a couple of public releases per month, more if you are in our Slack team.
It has even more of @side OptLos super smooth speed optimisations applied…. - It's super smooth!.
Installs about 850 meg in system before gapps
Doesn't work
Casting
MHL video
Does work
BT calling.
SE Linux is set as permissive.
Wifi is working well.
Hotspot may have problems on version 06 / 07 - confirmation needed / logs needed????? Nobody reads this obviously.
GPS is great.
Make sure your partitions are formatted as EXT4. Do not use F2FS on pie.
Not sure if CDMA phones work??
Magisk 19.0 works fine. Flash the zip after romfile. Once in android you may need to install MagiskManager APK if it is not present.
Magisk sound mods appear to work e.g. ViperFX.
Substratum uses OMS and the keyfile is now builtin for this is Now built into the rom.
To get pie home button gestures enable "navbar" in extensions, then "swipe up on home button" in gestures.
Sound changes may mean older sound mods no longer work.
The google sound app may crash if updated to version 2, leave as version 1.
This rom will not work / will never work on i9515, i9500 and i9506 variants of S4.

Reporting bugs​
Proper reporting of issues will help me spend time productively fixing bugs rather than tail chasing vague issues.
Please follow these guidelines.
Reporting bugs
If you wish to report an issue, then the onus is on you to prove the issue.
If you provide exact replication instructions, an idea of how often the issue occurs and logs that enable me to replicate the issue then a fix will be possible ("if you do action 1 then action 2 then action 3 you will find that bug X occurs 100% of the time").
If you give a vague complaint about an issue then I will not look at it without explicit replication instructions and preferably logs ("phone overheats when using game XYZ").
Issues about overheating, battery life or performance should be backed up with information from relevant monitoring apps.
One-off issues generally do not get investigated unless they are well documented and have provided logs.
Issues that are specific to one piece of software will generally not get investigated without logs. I am not very keen on installing software to investigate bugs, especially if I need to create user accounts. If you can replicate the issue on more than one piece of software it will increase the chance of being fixed.
Issues to do with speaker or microphone related issues need to be explicit about which speaker and mic is in use (internal, head phones, earphones, bluetooth headset, Bluetooth speakers), whether normal earpiece or hands free mode is in use, Audio mods that have been installed. Logs may be helpful too.
Issues with media / streaming / playback should be provided with examples.
A picture is worth a thousand words; a movie is thousands of pictures. If you cannot describe your problem in words, post pictures or movies to help show your issue. The rom has in-built screen capture and screen recording tools, so please use them.
It can often be difficult to tell what is going on with logs from a fully loaded system. It can help if you make a nandroid of your current system, format and then make a clean install, with gapps only if needed, and only the app that causes the issue - as minimal a system for replication as possible - then replicate the bug and capture logs. If I then have to replicate the issue I can easily replicate your system.
If you want to send logs for a bug, I would like you to use Syslog.
Perform some of the functionality that is bugged and then capture logs in the app.
If you have had a reboot then capture a set of logs immediately when the system reboots. If the last-kmsg file is empty then the logs are useless.
Type a brief description of the problem in the notes field and your XDA username .
Select to scrub personal information.
Upload it to a web based host (gdrive, dropbox, etc.) and PM the link to me.
And remember:The Drill ....

If you give a vague complaint about an issue then I will not look at it without explicit replication instructions and preferably logs ("phone overheats when using game XYZ").
Issues about overheating, battery life or performance should be backed up with information from relevant monitoring apps.
One-off issues generally do not get investigated unless they are well documented and have provided logs.
Issues that are specific to one piece of software will generally not get investigated without logs. I am not very keen on installing software to investigate bugs, especially if I need to create user accounts. If you can replicate the issue on more than one piece of software it will increase the chance of being fixed.
Issues to do with speaker or microphone related issues need to be explicit about which speaker and mic is in use (internal, head phones, earphones, bluetooth headset, Bluetooth speakers), whether normal earpiece or hands free mode is in use, Audio mods that have been installed. Logs may be helpful too.
Issues with media / streaming / playback should be provided with examples.
A picture is worth a thousand words; a movie is thousands of pictures. If you cannot describe your problem in words, post pictures or movies to help show your issue. The rom has in-built screen capture and screen recording tools, so please use them.
It can often be difficult to tell what is going on with logs from a fully loaded system. It can help if you make a nandroid of your current system, format and then make a clean install, with gapps only if needed, and only the app that causes the issue - as minimal a system for replication as possible - then replicate the bug and capture logs. If I then have to replicate the issue I can easily replicate your system.
If you want to send logs for a bug, I would like you to use Syslog.
Perform some of the functionality that is bugged and then capture logs in the app.
If you have had a reboot then capture a set of logs immediately when the system reboots. If the last-kmsg file is empty then the logs are useless.
Type a brief description of the problem in the notes field and your XDA username .

Upload it to a web based host (gdrive, dropbox, etc.) and PM the link to me.

first! oh wait.... can I really get first on my own thread?
anyhow.... we present for your delight and delectation - Resurrection Remix Pie 2.99_preview
2.99_preview??? What the F with your version numbers Buff?
Well I promised I would release V3 builds with February updates and working Bluetooth calling.
And next week we will indeed release versions of all our roms with February updates and the newly added JDC feature of working BT calling, but we couldn't resist a little preview, so hence 2.99_preview.
So expect a new build of this next week with February updates also.
But really it's stable, fast and tweakable and perfectly useable.
Did I mention BT calling LOL?

YAY another rom. Thank you @Buff99 and @side for your hardwork

congratz

Again and again and again.... We never stop

Another one with <3
Thanks guys specially for you Buff about this amazing work

@Buff99. Idk what to say, Thank You?? I feel like this is not enough.?
This was the first rom I ever used on my s4(probably got it around the end beginning of March.
I would love to test this rom very much since I haven't been on much after I got my s4 fixed.
See You on Slack. Can't wait for next release ??.

Welcome back again

After all these years...bluetooth calling is making a comeback?
Your ROM was and will always be my favorite one.

Thank you @buff for RR Pie. It's working fine, just two small things i recocnized:
1.. I'm missing the option to unlock the lockscreen by PIN without entering OK/Enter. I can't find this option in securitysettings nor the RR-settings
2. In RR-settings i get force close of settings app by choosing "System UI tuner" in UI settings
I did a clean install.

It's just because they fixed Bluetooth calling so it's just a preview for it before they bring it to the rest of their roms. @Buff99 I hop in correct. :silly:

Pretty much. Explained in post #6 I thought.....
We wanted to get something out with BT calling early, that's all that preview means... to let those people who must have BT calling available preview pie.
There is nothing wrong or cut back or pre-production about this rom. It's the real deal.

Thanks for the beautiful ROM @buff. I have a issue on bluetooth. I connected my phone with my Bluetooth speaker after a few moments Bluetooth automatically off and on and then Bluetooth crash.
Here is the log link - https://del.dog/ekabajubag
Sorry for my bad English. Hope you can understand it. Thank you.

Yeah BT still has some issues we are working on, retry with v3 when it arrives.
The combined WiFi / BT chip is the most hideous thing ever, so much that Samsung even had to hack around it in original firmwares.
If you can disable WiFi before using BT you may find it more stable.

Contributors
Buff99, side
Source Code: https://github.com/GZOSP
ROM OS Version: 9.x Pie
ROM Kernel: Linux 3.4.x
ROM Firmware Required: Lollipop compatible
Based On: AOSP
Version Information
Status: Stable
Created 2019-07-06
Last Updated 2019-12-26

Installation​Required for installation: Recovery - Latest recommended JDC TWRP Recovery v3.3.0-0 for JFLTE: HERE.
If you require a LOKI-patched version of TWRP, try this version patched by @mattgyver.
Firmware - Lollipop supporting bootloader and modem / non-hlos. Look in _Bon_Bon's great MODEMS and BOOTLOADERS collection​.
The following are "best practice" recommendations for installation, you may be successful using your own routine.
1st install - " clean install "
Make a full nandroid backup <always backup!>.
** OPTIONAL Properly remove previous root solution (recommended - flash Magisk uninstaller and UnSU). **
Fully wipe device (At least system, cache, dalvik and data. Recommended - fully clean by wiping internal and external SD).
Make sure your partitions are formatted as EXT4. Do not use F2FS on pie.
Install Rom.
Install desired root solution. (see post#4).
Install Gapps (Pico or larger).
DO NOT Wipe cache and art / dalvik (rom is partially pre-deodexed).
Reboot.
Wait for 1st boot.
Enjoy.
2nd and subsequent installs - " dirty flash "
** OPTIONAL Uninstall all Substratum overlays ** .
Make a full nandroid backup <always backup!>.
Properly remove previous root solution (recommended - flash Magisk uninstaller and UnSU).
Wipe system, cache and art / dalvik (wiping system is ESSENTIAL for Magisk).
Install Rom.
Install desired root solution. (see post #4).
Install Gapps (Pico or larger).
DO NOT wipe cache and art / dalvik (rom is partially pre-deodexed).
Reboot.
Wait for app optimisation.
Enjoy.
While dirty flashing may be possible for some updates, be prepared that progress means you will occasionally need to clean install updates (usually when settings files are changed)!
Nandroid backups are your friend!​

Current issues
Release 03​
This rom is more of a classic AOSP style rom. Not much in it, not much to tweak.
Clean n lean. Do with it as though will.
Don't work
MHL video (? we think ?)
Does work
Miracast / casting.
BT calling.
SE Linux is set as permissive.
Wifi works well
Hotspot works well.
GPS works well.
Make sure your partitions are formatted as EXT4. Do not use F2FS on pie.
Magisk 19.3 works fine. Flash the zip after romfile. Once in android you may need to additionally install MagiskManager.
Magisk sound mods appear to work e.g. ViperFX.
Substratum works fine.
Quickstep launcher is a very basic version, don't expect to tweak much. Google feed won't work for you.
Recommended: use an alternate launchair like Lawnchair 2.
Sound changes may mean older sound mods no longer work.
The google sound app may crash. Use version 2.1.
This rom will not work / will never work on i9515, i9500 and i9506 variants of S4.

Reporting bugs​
Proper reporting of issues will help me spend time productively fixing bugs rather than tail chasing vague issues.
Please follow these guidelines.

If you wish to report an issue, then the onus is on you to prove the issue.
If you provide exact replication instructions, an idea of how often the issue occurs and logs that enable me to replicate the issue then a fix will be possible ("if you do action 1 then action 2 then action 3 you will find that bug X occurs 100% of the time").

And remember:The Drill ....
​

Hardware button customization seems to be borked. The Menu/Recents button cannot be configured at all; default actions stay active whatever you select. The same seems to be true for the Back button.

Release 2 ready to download;
August updates, Wake on Home, HWkeys fixed

as pure basic rom this seem to work great not seeing modem and bluetooth dropping . i do miss the status bar changing or even lite notification light setting like i see in 8

Release 03 is available now.
September 2019 security patches.
Miracast / casting enabled
performance tuned - Interactive governor & AutoSMP
Buffcore kernel 10.0
Row IO scheduler set as default

Thanks for this one Buf99! This ROM deserves more attention

This rom is EOL (End of life) so will get not further development.
It hasn't been updated by GZ team since the September security updates.

Some of you may know me at S4 forums. As promised, I will support S4 for yet another year.
So here we are. In this thread I will give you a small bite of S4 with Android 11.
Some of you may have some questions.... So lets get it started.
-What's working?
-I will start by saying what's NOT working:
Camera (it's 50% fixed though).
You tell me.

Could anyone easily explain why kernel 3.4.112 is still used,
even though @Buff99 (in AICP and in GZOSP) and @-+BB+- (in AOSP) did ROMs on kernel 3.4.113?
.

Hello there, did I do anything wrong in installing the Rom?
1. Wiped data, cache, system, dalvik.
2. Install Rom.
3. Install Bitgapps.
4. Install Magisk 21.
5. Reboot to system.
After boot my system holds maybe 2 minutes, then always a soft reboot. Would like to test, but I can't test when the Rom doesn't run without random reboots every 2 minutes, otherwise nice work @side

This is a preview build, not a daily driver Doesnt like gapps and magisk much at this time.

Great to see active work going on bringing LOS18 to the Galaxy S4 - thanks!
Maybe someone can give me a better understanding of the following questions (which I also wanted to know already or LOS17, but never asekd):
how are the dependencies/relations between LOS18-optimized to the (hopefully later released) LOS18-official/nightly? Are these completely different branches from beginning? Or are commits from LOS-optimized-branch added later to the nightly-branch or other way round or are they completely separated?
can I switch between LOS18-optmized (if it is more or less stable) and LOS18-official (if available, or: same question I want ask for LOS17.1-optimized-vs-official) and vice versa without destroying LOS- and app-settings / need to make factory-reset?
where are exactly the differences (improvements) between official and optimized (for 18 as well as for 17.1 which I currently are using)? I guess there exists a documentation, but did not found.
is work done here for S4 / i9505 also usable by other maintainers of others S4 versions (e.g. i9515)?
if using LOS18-optimized - is there the internal updater available and working (as I know from 17.1-nightly), and from which repository it downloads the images?
Cheer, Robert

Umm... I got a problem. After installing gapps, sometimes it reboots for no reason and gliches the reboot with white bars

Hi . Please this working for s4 i9515 . Thanks

It is always better to test a very early stage ROM without any Gapps and Magisk. However in this case I feel it's Magisk causing the problem. Try without it (or flash Magisk after first boot), if it's still doesn't boot, also try without Gapps.

Long live side da great

Thanks @side for making Android 11 for our jf this long.

Side you are the king baby

Superb audio quality for USB (UAC 44.1kHz 32bit) and Bluetooth (LDAC).
Noop I/O scheduler is not bad for audio (BFQ has disappeared).
I found two "Android Services Library" system apps in this ROM. One is "android.ext.services" and the other is "com.google.android.ext.services". Is this normal?

Sorry. I confirmed that "com.google.android.ext.services" came from "BiTGApps-arm-11.0.0-R19_signed" (I have installed this and Magisk 21.1 on this ROM). I was able to disable "com.google.android.ext.services" without problems.

Ok. Got it. Change bin extension to zip. Simple as!!

Really nice work and Rom from thr JDC Team!
Unfortunately I experience some bugs:
Bluetooth does not reliably enable from the quick settings (automatically turns off again)
- for WiFi, sometimes networks are not found and an empty list is shown . switching to flight mode and back resolves this.

Awesome release. I like this one far better than [JDCTeam] Optimized LineageOS17.1 v8.0 (... mainly because I experienced random crashes with it).
The phone feels a lot faster running this ROM compared to the above mentioned, however I already encountered some small issues:
> Google Maps latest version (from Google Playstore) seem to have an issue with Android 11, therefore had to downgrade manually to 10.54.0 (https://www.apkmirror.com/apk/google-inc/maps/maps-10-54-0-release/) to fix the issue.​> Similar issue was encountered with latest "Vanced Youtube" release - something about Google Play Services not being supported on this device. A downgrade to to 15.33.34 fixed it.​> Android 11 seems to have removed global "Immersive Mode" and now its up to apps to implement it? Is there an app that still works (don't care if its per app basis or global as long as it works) ? Anyways, please try to bring it back Q.Q​> Home Screen "Search" feature does literally nothing.​> I can't seem to find screen pixel shutdown feature (was it called screen dimming or smth?) that was available in LineageOS17.1 v8.0 for AMOLED screens, then again its not a mandatory feature, but I appreciated that extra battery life.​> Battery Charging statistics on lock screen seems to be missing too unlike LOS17.1 It was useful to know if my charging cables were faulty.​
I did experience some random restarts, but can't confirm if it was the ROM problem or it was me messing with ADB , experimenting to transfer ~10GB of data via USB and Wireless at the same time, so maybe I overloaded something by attempting that among other things xD
I didn't experience Bluetooth or Wi-Fi issues so far, seems way more reliable than the LineageOS17.1.
Furthermore, I did use the "Aroma Installer 10" and I can say that the Magisk Manager is either bugged or the latest version simply doesn't allow to Install Magisk automatically anymore - it allowed only downloads and even then the magisk.zip threw errors upon flashing via TWRP. Manually downloading Magisk v21.1 from https://github.com/topjohnwu/Magisk/releases and flashing it did work tho ;]
Anyways, keep up the awesome work! I'm a big fan of all Optimized LineageOS releases

I experienced this too. My other small issues are,
USB OTG memories cannot be used (but I can use USB DAC's)
Bluetooth aptX codec's default sampling freq. is 48kHz (changeable to 44.1kHz after connected), while SBC&AAC's default are 44.1kHz.

Greetings I have this room for daily use since it left and I can notice that it loses the wifi and is less strong than normal the other detail is in wassap the voice and audio and group calls presents a failure nop works well that alone would be important to solve those two things rest is beautiful androit 11 congratulations

This rom works flawlessly on my Samsung Galaxy S4 SGH-M919...I have 2 great suggestions....the Ambient Display when Notifications arrive and the Always On Display...I like those two.

Spotted a weird bug with the quick settings panel:
The icons just disappear sometimes. They do come back if you expand it further. I though it was just dark mode thing, but same behavior happens with light mode too. I noticed the bug started to happen once I edited (added more buttons) the quick settings panel.
-- EDIT
I fixed it or more probably caused it via "SystemUI Tuner" by enabling "QS Fancy Animation" setting.

Hey guys!
maybe I'm really blind, but I can't find any ARM Gapps for Android 11...
any suggestion or (better a) link?
thank you.
