[SM-G850F][SLTEXX] LineageOS 14.1 UNOFFICIAL BETA9 (Nougat) - UPDATE: 2017-11-30

[modpunk]

ABOUT THE GALAXY ALPHA LINEAGE PROJECT

I'm trying to get LineageOS working on the Galaxy Alpha. This ROM is not complete. There are still features which are not fully working and there are for sure things which need bugfixing. Please check the Known Bugs section before reporting issues. The ROM is beta state because it isn't complete and probably will never leave beta state. There are too many things which are not working correctly and supporting Exynos is a tough task.

I work on this project for FREE and putting in a lot of my free time hours into it. A small donation would help to buy better tools to improve the development some day.

RECOVERY

To be able to install the ROM you need a recovery. I suggest to use my TWRP Recovery build. You can find it here.

BACKUP

Before installing the ROM you should create backups. The most important backup is to create one of the EFS partition and store it on safe place on your computer. If something goes wrong you need to restore this partition. It holds information about your device, like the MAC address for your wifi and information for the radio.

DOWNLOAD

Download BETA

ROOT/SU ADDON

The ROM does not provide root access! For root access you need to flash the su-addon.

FLASHING THE ROM

As this is an Android based ROM you need to flash sboot (bootloader) and the modem image from one of the latest official Samsung releases. Or install a ROM via the Samsung update option. You can find the latest stock ROM here. Suggested modem is from a ROM version: G850FXXS2CQD3 or newer.

I suggest to put the ROM on a USB disk and use a USB OTG cable to flash the ROM. It is also possible to put it on the emulated sdcard and flash it from there.

GAPPS

I suggest to use Open GAPPS.

REPORTING BUGS

Give the programmer some credit for basic intelligence: if the program really
didn't work at all, they would probably have noticed. Since they haven't
noticed, it must be working for them. Therefore, either you are doing something
differently from them, or your environment is different from theirs. They need
information; providing this information is the purpose of a bug report. More
information is almost always better than less.

Before reporting bugs, please check the KNOWN BUGS list below and read THIS HOWTO

My modem doesn't work, what can I do?

Did you flash the latest MODEM firmware from the latest Lollipop release? The suggested firmware is at least G850FBOU1COL3 or newer

How do I use adb/logcat go get logs from my device

You can find a good tutorial here.

i tried to install this rom, but get this problem from twrp: "Can't install this package on top of incompatible data. Please try another package or run a factory reset".
I have stock LL on 850F. Twrp is the 3.0.3. I had problem even with cm13, so i think that it's my phone fault. How can i solve?
thanx

Hi @modpunk, first thank you for your amazing work.
I flashed your rom and after a couple of hours of use i noticed some bugs:

1) apn data empty
2) data not working after manual apn insert
3) red border display flickering
4) metallic voice call
5) error during carrier search

that's all for now.....

1) Then something is wrong with linking the database to the correct location
2) See 1)
3) This is a engineering build, I forgot to do a userdebug build. The red flashing is normal and means it does a full screen redraw
4) Which would mean you might have an old modem flashed.
5) I need to look into it

so, for point 4) where i can find the newest modem? i can flash it with odin?
And for point 2), why data don't work even after manual apn insert?

2) The cbd needs access to two data bases and they have a different location in Andorid 7.1. So I created a link for the directory so cbd can find them in the old location. However doesn't seem to be working as expected. I guess I have to remove them and flash and see what is going wrong. I created them manually when I started to work on 14.1

Update TWRP first!

Beta2 is up!

 

[pipus1974]

Hi modpunk.

First of all, thank you for your work.

I ask you if the ROM is pre-rooted or there is a possibility to choose if root the device or not in "developer options" such as CM13 (now I use it with my complete satisfation).

More and more essential apps (such as banking operations or live video streaming) need unroot device in order to become the best choice for daily use.

Thank You again.

I fixed the issue with the APN databases.

dirty flash beta2 over beta1 and apn problem still remain. I'm the only one?
