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

Status table explanation

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

Component Status notes
Screen P Screen may go crazy sometimes (tested with Plasma Mobile)
Battery P Percentage reporting works; no charging status reported, but charges without problems


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. Then download the following Repo and copy the folders to the pmaports/devices/testing folder.

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

$ pmbootstrap install
