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, but it is not very usable yet (clocks are broken, and it doesn't seem to boot into initramfs). See the WIP mainline kernel repository and User:knuxfanwin8/Grand Neo mainline journal.
Element type | Element | Status |
---|---|---|
Chipset | BCM23550 | DTS in mainline |
Graphics | Videocore IV | https://github.com/anholt/mesa/wiki/VC4 |
USB | FSA9485 | 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 | Google_Galaxy_Nexus_GSM_(samsung-maguro) claims that there's a driver in mainline for this touchscreen, but links to the mms114 driver instead. |
WiFi, Bluetooth | BCM4330 | Driver in mainline |
Display | HX8369, SC7798 | 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) | s5k4ecgx is in mainline, db8v61m is only in Broadcom downstream. |
PMU | BCM59054 | There is a driver in mainline for the simmilar BCM59056 (bcm590xx), the author said he was working on adding BCM59094 support but it never seemed to get into mainline (judging by this post it seems like the only difference are the regulators) |
Backlight? | KTD3102 | Not in mainline. |
Proximity/ambient light sensor | Sharp GP2AP002 | Driver in mainline |
Geomagnetic | Alps HSCDTD008A | Driver not in mainline |
Accelerometer, magnetometer | Bosch BMC150, BMA2X2 | Driver in mainline |
