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