// Info
It's unnoficial LineageOS14.1 for Galaxy S4 Jfltexx (GT-I9505).

// Info
I strongly recommend to perform a backup of your current rom before installation.
Regarding going from unofficial builds to official - or official to unofficial builds that can be done by as described here:
To migrate from unofficial build to official or official to unofficial:
1. download this script
2. ensure that file has LF (UNIX-style) line endings
3. put it on your phone
4. reboot into recovery
5. make a full backup!
6. go to the folder where script is located
7. run: ./migrate.sh official
8. WARNING! rebooting phone now would end in data corruption!
9. flash the official build now (after flashing official build it is safe to reboot)
10. flash Gapps (and any addons)
11. reboot

Installation Procedure : coming from stock rom
TWRP - Odin flashable (I use Odin 3.12)

Build from xx.xx and Gapps + Magisk Root to external SD
01. I take the battery out now, then battery in again and off into the download mode.
02. flash TWRP with Odin (comes in AP). The hooks at Auto Reboot and F. Reset Time out.
03. disconnect USB cable after flash, battery out and in again.
04. boot into recovery -> Allow Modifications
05 Advanced Wipe: Dalvik/ART Cache, System, Data, Internal Storage, Cache (lasts a while)
06. install -> select lineage image, then add more zips and gapps, Magisk then flash
07. patching system image unconditionally runs through with progress bar
08 Open Gapps are flashed, progress bar runs through
09. when done, tap reboot system, Swipe to install TWRP app (or not, if you don't need it)
10. reboot
11. los 14.1/boots. (quite a while ^^)
12. type through the facility
13. read

[B][U]since some users have already asked me about new features[/U][/B]
Since it is a pure lineageos version 
and not as optimized as for example from side.
 All I do is to get your mobile phone Up-To-Date 
and The errors that I do is release themselves or after every update 
[B][U]I hope you understand that I don't make any changes to the version[/U][/B]

Looking forward to flashing

Thanks for the new build. One thing i like already is the file size. Nice and small. I like to run lean as possible. I will test it out and see how it rolls.:good:
