How to enter flash mode
- Download mode: + + and press
- Recovery mode: + +
Installation
1.Run
pmbootstrap init
2.Select device codename as goyavewifi (do not confuse with goyawifi or goya)
- You can select anything except anything runs wayland
3.Run
pmbootstrap install
4.If your images size larger than 1500 mb you cant install to system (pmbootstrap flasher flash_rootfs --partition userdata
doesnt work for no reason. but you can install with twrp or use a sdcard)
You need to export image file and flash with heimdall.
5.run
pmbootstrap export
6.run
heimdall flash --userdata ~/.local/var/pmbootstrap/chroot_native/home/pmos/rootfs/samsung-goyavewifi.img
7.run (crucial for changing rootfs)
pmbootstrap flasher flash_kernel
8.Done!
Now you can ssh into your device!
Notes:
If your device doesnt show anything(just samsung galaxy tab 3 lite screen and nothing) try to ssh 172.16.42.1 if ssh throws error connection refused wait for 1~2 minutes. If still showing this message you have a problem with kernel(probably)or rootfs. Try flashing again.If this doesnt work either you can try different DE.
If you can connect ssh you probably can run
sudo startx
Display
- in landscape
- No DRM support, cannot run wayland.
- No splash when booting and power off, happens after applying Spreadtrum swapped colors patch (Without the patch, Xorg crashes, both probably because the display is 16bit).
- pbsplash fails with
tfb_acquire_fb() failed with error code: 7
.
- pbsplash fails with
- for any DE installation that uses lightdm (for example; xfce, mate), you need to install postmarketos-base-downstream
- blanks after inactivity, likely some power-saving feature
echo 0 > /sys/class/graphics/fb0/blank
turns it back on
- fuzzes out after wake from suspend, weird display glitches
- X fails with
FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument FBDEV(0): mode initialization failed Fatal server error: AddScreen/ScreenInit failed for driver 0
- lxqt ghosts on default theme (only in taskbar) and notifications.
- a quick fix is automatic hide option on taskbar settings.
- if you want to change the scale (in lxqt)
/home/user # sudo nano /etc/environment
(in nano add these)
QT_SCALE_FACTOR=0.75
QT_AUTO_SCREEN_SCALE_FACTOR=0.75
Audio
- Needs soc-sprd-audio-sc8830 package
- Headphones and back speaker works
- Headset and Handset only gives microphone and it's low volume, but
/usr/share/alsa/ucm2/conf.d/sprdphone/HiFi
can be patched to fix both. Like this
PulseAudio
Need to add add these lines at /etc/asound.conf:
defaults.ctl.card 1 defaults.pcm.card 1 defaults.pcm.device 1
Also need to edit this line in /etc/pulse/default.pa:
load-module module-udev-detect
To:
load-module module-udev-detect tsched=0
WiFi
You can copy /system/etc/wifi from stock rom to the device, then wifi works.
Steps to fix wifi 1.Download wifi firmware below or extract yours from stock system image.
- If you want to extract yours, you need to use an system unpacker.
2.Copy the wifi
folder to your sdcard.
3. run this command(s):
/home/user :# mkdir /system
/home/user :# mkdir /system/etc
/home/user :# cp /[your wifi folder path or sd card]/wifi /system/etc/
/home/user :# reboot
# [later than reboot]
/home/user :# nmtui # nmtui --> activate connections --> wlan0/your ssid and password --> ok
Done! Now you can use your wifi without issues!
Added them here: HAKANKOKCU/firmware-samsung-goyavewifi
Couldn't get firmware-aosp-broadcom-wlan working.
One weird issue is it seems to not connect at all, but you have to use nmtui for first connection. then it just works.
Useful tips
You can access your (pmOS) internal storage using this command;
/home/user # tcpsvd -vE 172.16.42.1 21 ftpd -A /
Adding files fails with
500 Unknown command
You can add username logins:
/home/user # tcpsvd -vE 172.16.42.1 21 ftpd -a user /
You can change the directory:
/home/user # tcpsvd -vE 172.16.42.1 21 ftpd -A /path/to/the/directory
You can mount your sdcard
/home/user # mkdir /sdcard /home/user # mount /dev/mmcblk1p1 /sdcard
You can also use udisks2 and gvfs, but sometimes doesn't work. For NTFS, you need ntfs-3g
Making it permanent
- You can make mounting sdcard permanent;
/home/user # ash -c "echo 'sudo mount /dev/mmcblk1p1 /sdcard' > /etc/local.d/sdcard.start /home/user # chmod +x /etc/local.d/sdcard.start
You can mount system partitions:
/home/user # mkdir /system /home/user # mount /dev/mmcblk0p23 /system

Input
HID buttons
- event0: sci-keypad
- home, power, volume keys
- you can check raw data from
/dev/input/event0
- you can check raw data from
- home, power, volume keys
Touchscreen
- event1: MELFAS_MMS449_Touchscreen
- in portrait
- includes "Recents" and back buttons
- stops working on suspend,
cat /sys/class/input/event1/device/device/device_enable
reenables it - try a non-forceful reboot if it doesn't appear
- Touchscreen Fix: you need to add this to
/etc/X11/xorg.conf.d/00-fbdev-rotate-CCW.conf
Section "Device" Identifier "LCD" Driver "fbdev" Option "Rotate" "CCW" EndSection
- Note:this changes screens rotation
- You can also add this at
/etc/udev/rules.d/00-touchscreen-dev.rules
:
SUBSYSTEM=="input", ATTRS{phys}=="1-0048/input0", ENV{LIBINPUT_CALIBRATION_MATRIX}="0 1 0 -1 0 1"
This needs a full reboot.
Headset
- event2: headset-keyboard
- works
Accelerometer
- event3: accelerometer_sensor (STM K2HH)
Have to do this to get it working:
# echo 0 > /sys/class/input/event3/device/poll_delay # echo 1 > /sys/class/input/event3/device/enable
You can confirm it working with evtest
Issues or Errors
- Did you notice that error in fdisk output above?(also occurs on gparted)
- To fix that error, just enter fdisk and write the changes.
And error is gone.
But comes after a reboot (idk why)
- Error details:
GPT PMBR size mismatch (15253503 != 15269887) will be corrected by write. The backup GPT table is corrupt, but the primary appears OK, so that will be used. The backup GPT table is not on the end of the device.
- Fdisk verify output:
No errors detected. Header version: 1.0 Using 25 out of 128 partitions. A total of 38845 free sectors is available in 2 segments (the largest is 15 MiB).
- In any DE with polkit, sometimes an error occurs that policykit has crashed. so any apps with root/changing brightness will not work. It sometimes works, sometimes doesn't.
No matter what, in dock or app menu no apps are displayed. So don't use xfce.
