Tips
To enable Developer options go in Settings->About device and press "Build number" for 7 consecutive times.
STweaks shows "no kernel support", what to do? Go in Developer options and enable root.
Using F2FS
What it is? Wikipedia
To use it you should first convert your EXT4 partitions through recovery, before installing this ROM.
On PhilZ:
Wipe and format options->custom format options->toggle ext4 f2fs migration
Format cache->f2fs
Format data and data/media-> f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)
On TWRP:
Download and install this TWRP version: https://www.androidfilehost.com/?fid=24269982086988952
Wipe->advanced wipe
Select cache->change or repair file system->f2fs
Select data->change or repair file system->f2fs (Warning: internal storage is formatted, make a backup of your personal data before doing this!)
Now you can install this ROM following installation steps in post above

Lets rock...

@AntaresOne proves once again that he is a Recognized Developer even though that title is not attributed to him yet. Hopefully soon...:good:

Antares! Time for a Android 5.1 Updater?

Is the f2fs conversion a must for this, or can I leave my partitions ext4 and install?
Thanks AntaresOne

Thanks !!!! Could it boot with multiRom or none of the kernels could support it ? Thanks in advance

ohh eaa
backup in progres... thank's

You can also leave ext4, but with this ROM the system partition will be automatically converted to F2FS

In official 5.1 no. It should be fixed on some next release. BTW i know that exists a xposed module to fix it. In that thread i have read that on cm12 is useless because a patch for fixing memory leak has been already apllied. I don't know if it's already included in this rom

I just know that this problem is annoying as hell and very "intrusive", i.e. I see it all the time on my phone, every app which is closed for 5 minutes or so, sometimes even seconds, has to be reloaded...

But from what i have read, what are you saying it's not memory leak problem of android L. Memory leak is totally another thing

installed over cm12 (21/03/2015) after wiped cache,dalvik,system.
rebooted correctly, but stweaks doesn't start beause kernel not supperted issue and audio crazy shutters during call... btw rstored old backup

All Variants with a locked bootloader are currently unavailable until the unified tree is further updated.
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 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.​
UNSUPPORTED DEVICES
GT-I9515 is not / will never be supported (slightly different hardware)
GT-I9500 is not / will never be supported (completely different hardware)​

Other variants may require a different recovery. ​
INSTALL
Move any files you want to keep to PC - or you will lose them !
Make sure you are using the unofficial JDC version of TWRP above. Earlier versions will give Updater process ended with ERROR: 7.
Download the Optimized LineageOS rom , root solution and a Gapps 8.1 package (nano / pico or larger) for arm
Move the Optimized LineageOS rom, root solution and Gapps package to external storage
Boot into recovery mode (hold volume UP, HOME, and POWER button for 1 second after vibrate)
Wipe > advanced wipe > select (enable / tick) for Dalvik / Art Cache, System, Data, Internal Storage, Cache
Swipe to wipe at bottom of screen
Back to main start screen
Wipe > format data
Type ‘yes’ and press blue checkmark at the bottom-right corner
Back to main start screen and select Install to install rom, root solution, Gapps and Aroma.
DO NOT wipe cache / dalvik / art after flashing as this rom is pre-deodexed
Reboot System! Enjoy!
Once first boot is completed you can safely move your files back to Internal Storage
NOTICE:
First boot after an install / update takes a while, wait at least 5 - 10 minutes for it to boot.
Phone will be hot / slow after first boot as dex optimisation of your apps occurs and media catalog is built of your audio / video files.
If the LED stops flashing and goes solid with any color then SuperSU did not correctly trigger the reboot. You can either pull the battery -OR- hold down the power button for 15 seconds till the led / screen goes blank, then let go of the power button. Then after another 4 seconds it will automatically boot and vibrate and everything is 100% normal. It only happens that one time on a new Rom install with SuperSU.​
-----------------------------------------------------------------------------------------------------------------------------------------------
JDC aroma flashable addon
This is an optional addon that needs flashed through TWRP after rom, SU and gapps.
Download from HERE.
It contains working tested versions of:Adaway, Arise, AudioFX, Bromide, Buffcore Aduitor, Eleven, Google Camera, Magisk, Magisk Uninstaller, Mixplorer, Snap, Toolbox, YT Vanced, Wallpaperpicker​
The Buffcore branded version of kernel auditor is the full version. It has a settings page for boeffla wakelock blocker editing and a spectrum switcher page, so no longer need spectrum app, and other JF specific tweaks.

​
​
BT calling from headsets or cars MAY not work now. Stay tuned.
Wifi uses the region set in your phone sim, if you don't have a sim your region may get incorrectly set. See here
​
Since ROM supports all (SuperSU,native root,magisk) JDCToolbox is coming as a flashable depending on your root method.Download the one that fits you

Some notes from me:
Use opengapps 8.x and ARM ..not ARM64
Ledify custom pattern
Some notes about ledify. In case u need some "hardcore" edits or even create your own ledify patterns
here is a small tutorial:
at /system/bin/ledify the script exists.
as you can see at line 236 , the default pattern is the 'heartbeatblue'.
your options are:
disabled)
heartbeatblue)
heartbeatgreen)
heartbeatred)
jdcdefault)
nexus)
nexusreverse)
police)
secdefault)
if u want to create a new one do this :
go to line 70 and add a function with the name u want.lets say OPTCM
Code:
OPTCM() {
//write your routine here as the others.
}
now go to RUN() and add
Code:
optcm) OPTCM;;
finally go to final lines where it says
Code:
# Default
PATTERN=heartbeatblue
and change it to
Code:
# Default
PATTERN=optcm
save the file and u r ready.
For better results u better go to twrp,mount the system partition,take the ledify file to your pc,edit it and push it again back to it's location.

BUFFcore 2.09b - 2.12 changes
fully optimized toolchain flags;
reduced sleep timeout;
fastcharge properly functioning now - AC forced on highest you can attain and USB now working higher than 460mA
dynamic file syncing - early_suspend and dyn_fsync by default;
boeffla wakelock blocker;
print to dmesg log when a suspend gets broken;
Printing broken suspends to dmesg.log - you can check the dmesg.log file to see what is waking your device from suspend. Using SYSLOG, grep the dmesg for "active wakeup source" to see if you get any reports. Alarmtimer here is OK, other WLs are worth checking, then possibly adding to the blocked WL list if deemed safe.
Wakelock blocker : the following WLs are blocked by default -
Code:
qcom_rx_wakelock; wlan; wlan_wow_wl; wlan_extscan_wl; netmgr_wl;
NETLINK; IPA_WS; [timerfd]; wlan_ipa; wlan_pno_wl; wcnss_filter_lock;
_rx_wake; wlan_ctrl_wake; wlan_wake; qbt_wake_source
you can also ADD more yourself if needed to the following user file in ROOT
/sys/class/misc/boeffla_wakelock_blocker/wakelock_blocker​This will be a list delimited by ; semicolon and no-spaces. WLs should be exact case you find them.
So an example addon file would be
Code:
mmc2_detect;PowerManagerServiceWakelocks;msm_hsic_host
The wakelock blocker may give absolutely no difference to your battery life in suspend - It will only help if your issues are wakelock based. Monitor the log file for any broken suspends for a few nights, look them up in google to see what they are (some wakelocks are not safe to remove) then try adding any identified wakelocks to the user file.

🥧 Liquid Remix Pie 🥧 for S4 unified, ROM for the Samsung Galaxy S4
Contributors
Buff99, side
Source Code: https://github.com/LiquidRemix
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 2018-12-10
Last Updated 2019-12-26

Installation​
Required for installation: Recovery - Latest version of TWRP - 3.2.3-0
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. (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 ....

Great work so far! This is the first time since years that my S4 doesn't run on CM/LOS.

Contributors
Buff99, side
Source Code: https://github.com/ResurrectionRemix
ROM OS Version: 9.x Pie
ROM Kernel: Linux 3.4.x
ROM Firmware Required: Lollipop compatible
Based On: LineageOS
Version Information
Status: Stable
Created 2019-02-01
Last Updated 2019-12-26

Installation​Required for installation: Recovery - Latest version of TWRP - 3.2.3-0
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. (recommended - Magisk).
Install Gapps.
DO NOT Wipe cache and art / dalvik (rom is partially pre-deodexed).
Reboot.
Wait for 1st boot.
Run through Gapps setup.
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).
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!​

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.

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.

Other variants may require a different recovery. ​

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.
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 ....
​

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.
