Call for contributors! If you own this device, can make/already have a serial debug cable (using the Serial debugging#USB debug cable design) and have some kernel dev knowledge feel free to take a look at the current mainlining progress issue on the WIP mainline kernel repository and send any tips on how to fix the issues we're dealing with.

How to enter flash mode

Recovery: Power+VolUp
Download/Odin: Power+VolDown+Home

Installing

Follow the Installation guide. To flash to the device, boot into Download/Odin mode by holding the Volume Down + Home buttons while powering on the device, then run the pmbootstrap flasher commands to flash.

Notes

The device freezes under heavy load (such as installing certain apps through apk).

Audio works for a split second and then crashes.

Serial

This device uses the microUSB carkit debug cable, and works with 150K and 619K resistors.

By default, there's no bootloader log output; you need to mash the Enter key before "!" appears, then type "log", then reset. You should now be able to see the full bootloader logs. (See also: Samsung Galaxy Core Plus (samsung-cs02))

Mainline status

There's mainlining work being done for this device by knuxify; currently it can boot to the initramfs, but lots of stuff is still broken. See the current mainlining progress issue on the WIP mainline kernel repository.

Element type	Element	Works?	Notes
Chipset	BCM23550	P	DTS in mainline
Graphics	Videocore IV	P	Videocore IV is supported in mainline, but there is no DRM driver for the Kona framebuffer. Managed to get working graphics with simple-framebuffer.
USB-OTG switch	FSA9485	N	Similar to the FSA9480, which is in mainline. The only difference seems to be the addition of support for some old Samsung docks.
Touchscreen	MELFAS MMS144	N	Appears to be near identical to the MMS136, which is supported by the mms114 driver.
WiFi, Bluetooth	BCM4330	N	Driver in mainline
Display	HX8369, SC7798	N	HX8369 is in mainline, SC7798 is not in mainline. HX8369 is definitely used on the single-sim models, whether the SC7798 is used anywhere is unclear.
Camera	Samsung S5K4ECGX (rear) and Siliconfile(?) db8v61m (front)	N	s5k4ecgx is in mainline, db8v61m is only in Broadcom downstream.
PMU	BCM59054	P	Regulators are mostly supported; only missing feature is regulator modes. Still missing charger support, etc.
Backlight	KTD3102	N	Not in mainline
Proximity/ambient light sensor	Sharp GP2AP002	N	Driver in mainline
Geomagnetic	Alps HSCDTD008A	N	Supported in mainline by the Asahi Kasei AK8974 driver
Accelerometer, magnetometer	Bosch BMC150, BMA255(?)	N	Driver in mainline
