Installation

Before installing, ensure that your host computer and your copy of pmbootstrap is fully up to date and that your system has been rebooted since it was last updated.

init

$ pmbootstrap init

Select "samsung-kylessopen" as the target device and select a working recommended graphical interface.

Graphical Interfaces

install

$ pmbootstrap install --no-fde

See the 'in progress' section regarding full disk encryption.

flash

Ensure that the USB cable is disconnected, then hold down Volume Down + Home for a few seconds as the system boots. This puts the device in flash mode. Once in this mode, enter
$ pmbootstrap flasher flash_rootfs
to install the rootfs. Once this is finished, put yourself back into flash mode and enter
$ pmbootstrap flasher flash_kernel
to flash the kernel.

In Progress

Here is a list of tasks that are currently being worked on for this device, from highest priority to lowest.

Mainlining

Mainlining is an important task for this device, because kernels and drivers that supposedly work for this device are scattered across various git repositories, usually forks of other projects, often heavily patched and abandoned. Relying on kernels that can have their repos deleted at any moment, that are often heavily fractured anyways probably isn't a good idea.

All of these kernels claim to be for this device however, it's not known which of these kernels actually work and how well they work. FrankenKernel is the only exception as it is the kernel that gets flashed when installing this device. See Troubleshooting:boot.

Device regularly reboots itself

This is almost certainly a watchdog issue, since the device reboots every 10 minutes. I'm currently working on disabling the watchdog. pmaports#242

Internet connection

The internet works fine using USB_Internet however, thee are no interfaces shown that allow WiFi. This seems to be caused by the lack of the linux-firmware-ath6k firmware but even when loading it, it doesn't work. A kernel patch is likely necessary. See pmaports#248.

Audio

The msm-audio card is detected however, turning up the volume on any channel except the master results in a crash. See Audio and pmaports#249.

Device sometimes freezes while booting

Nothing is known about this issue yet.

FBDirect

FBDirect is a program that osk-sdl and charging-sdl rely on to work. See pmaports#250

FDE doesn't work

FDE doesn't work at the current moment. See FBDirect issue.

Error starting charging-sdl

The device boots into charging mode successfully, but charging-sdl doesn't launch, with "error starting charging-sdl". Check out the troubleshooting page, Charging-sdl and FBDirect issue.

Bluetooth

bluetoothctl doesn't do anything when run. It's suspected to be due to the firmware not being installed. See pmaports#248.

Scrolling graphics before DE

Before a desktop environment starts, the screen tends to flicker and scroll. It's a purely cosmetic issue. It's cause is likely related to the framebuffer and may be similar in nature to the FBDirect issue.
