  • Many, many more - install and see for yourself!

All following Galaxy S4 variants with Qualcomm Snapdragon 600 are supported:
  • GT-i9505 - jfltexx
  • GT-i9505g - jgedlte
  • GT-i9507 - jtfddxx

  • SPH-l720t -jflterefreshspr
  • jfltezm - China mobile
  • jfltecsp
  • jfltetfnatt
  • jfltetfntmo

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.

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.

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.

  • Move any files you want to keep to PC - or you will lose them !
  • Download the Optimized LineageOS rom , root solution and a Gapps 9.0 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
  • Make sure your partitions are formatted as EXT4. Do not use F2FS on pie.
  • Swipe to wipe at bottom of screen
  • Back to main start screen
  • Wipe > format data
  • Type β€˜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
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.

Go version:

Since i want the most for our jf , i created one more build. Its the Optimized LineageOS 16.0 - Go version

About "Reenable some Play Store apps" change.
All those years the main difference between official lineage/CM series and JDC roms is the unified tree.
By the term "unified tree" we actually mean "not-only-jfltexx support but any snap600 variant,using a common source code". Thats the simple explanation.
Although this unified tree was producing an issue that was really small and we couldnt see it....Our device was named (on its build prop) as jflte . The problem with this naming is , that , some apps from play store were complaining saying something like "this app is not compatible with your device" and though downloading the apk from 3rd party websites was working. The problem is centered around the situation where SOME apps are searching for device's name and trying to check if its compatible or not. Globally , there is no such device jflte but only jfltexx jfltecan jfltevzw etc...

tl;dr , version 3 has got this situation fixed by redeclaring the OFFICIAL device name while device boots.

a piece of history....

A few words about the new Pie builds.
After 4 years of being in ROM development game i am mainly messing with the jflte. Started as a tester, joined to JDCTeam with legends like @AntaresOne, @Alucard24 and such. Personally, for me, antares was the best jf developer ever, and still is. But thats a story... Starting developing the jf, i was following the device tree ( specific jf piece of code in order to make custom roms work ) that this team created... antares active dev was stopped at ~lollipop(?) something like that.after that i was kinda alone (with B--B) . Here comes the comes the comes the oreo...all those roms were made with those specific old jf device tree . Old stuff were still there...deprecated stuff...not needed stuff...

After all those years, i have to announce that the jf revived... Grandmaster arco68 and me(mostly him), sat our a$$ down and rewrite the whole jf sources again. many lines of code deleted...many added...many edited...proprietary blobs came...

So,now... 5 years after jflte release, i would like to present to you the most updated jf device ever existed...
Welcome to the new jfltexx , based on Android Pie
A new era of jf starts now

About the sources and 'open source' and such...a quick FAQ just in case ...

-Do you actually respect the licenses?
-Of course i do.Kernel source is there and licensed under GPL

-But device tree and blobs are private.I cant find them
-...and you wont find them. After the latest disrespectful behavior , me and @Buff99 decided to keep the sources closed FOR EVERY JDCTEAM PROJECT WE DO SINCE OREO OR NEWER

-Its not.If it was so, Samsung should release TouchWiz source code. Please go ahead and read about Licenses (Apache,GPL)

-Will we pay that for some kids who stole your stuff ?
-with one word..."yes". With more words "everyone let that thing be.So we are all responsible about this"

-Any chance to ever release the sources?
-"N" to the "O"... NO.

-Whats that Slack channel about ?
-Early builds for test, instant chat with the test team , support etc.

-What should i take care of Slack?
-When you firstly join, press on the tab "Channels" and join the following channels:
  • #buffrom_public - The next ROM of @Buff99 . Discuss/support etc. ( Why buffrom and not 'RR'? Join and learn)
  • #buffrom_requests - Requests for Buff's ROM
  • #legacy_rom_support - Support on EOL/finished projects by JDCTeam
