How to enter flash mode

Press and hold Volume Up + Volume Down while plugging it in the Computer. Then click Volume Up to confirm.

Unlocking the Bootloader

!!!WARNING!!!

This will reset your device to Factory settings and blow the Knox E-Fuse! You have been warned.

Samsung made this easy (thankfully): Reboot into Download mode (hold down Vol+ and Vol- while plugging it into a computer) and hold down Vol+.

This way, you can also relock the bootloader (with the only benefit being that the message at the Beginning is gone, no more Knox)

Installation

First, install pmbootstrap.

After that, set up the device to be used:

$ pmbootstrap init
Channel [edge]:
Vendor [samsung]: samsung       <- enter this
Device codename [i9100]: a52q   <- enter this
Enable this package? (y/n) [y]  <- you probably want non-free firmware
User interface [plasma-mobile]: <- choose any UI by your preference. Plasma Mobile works without issues :)
...

Then, create the rootfs image (and install it on sd card if you want)

$ pmbootstrap install (--sdcard=/dev/whatever_your_sdcard_is if you want to install to sd card)

After that, flash the kernel by doing

$ pmbootstrap flasher flash_kernel

and if you didn't install to an SDCard, flash the rootfs by running

$ pmbootstrap flasher flash_rootfs

After installation download emptyDTBO.img and flash using heimdall or TWRP.

Status table explanation

This table explains more in detail why some features are marked as partial (P) or Broken (N). Generally it's because feature works with some limitations, or is a "work-in-progress":

Component	Status	Notes
Screen	P	Changing brightness causes graphical artifacts(It's recommended to disable automatic brightness control)
Audio	P	Only audio from built in stereo speakers works.
Calls	N	Can recieve and make calls but call audio missing.

Notes

Issues with DEs etc.:

framebufferphone: has issues with Touch
xorg: doesn't work/crashes on adreno 618 (wayland/xwayland works fine)
