Information
Code name of the device is Midas.
For the LTE variant, see this page.
See the Samsung Galaxy S III page for more information.
How to enter flash mode

System Image
You can install the system to an SD card or make a recovery zip (probably won't fit in the partition size).
Be warned, the SD card will be formatted. |
To install the system image to an SD card, use:
$ pmbootstrap install --sdcard=/dev/mmcblk
Kernel Image
Boot into flash mode and then flash the kernel:
$ pmbootstrap flasher flash_kernel
If you have done everything correctly, your Note II should reboot and you should see the Samsung logo. All that remains is to wait for the pmOS splash to appear.
U-Boot
According to this blog, there is a working U-Boot port for the Midas devices. Build it from this repository.
Installation
This manual describes the installation on the SD card as a secondary bootloader.
Clone the repository:
$ git clone https://github.com/fourkbomb/u-boot
$ cd u-boot
Optionally, apply patches made by ave4:
- https://gist.github.com/ave4/b4ac6c8a3abd3fd5d5b9f255cb2719d3
- https://gist.github.com/ave4/3e30c7d10eba42e948a78176f4da4326
$ git am 000*
Set up the toolchain:
$ export ARCH=arm
$ export CROSS_COMPILE=arm-none-eabi-
Build U-Boot:
$ make midas_defconfig && make -jN
$ ./create_4412_sd_image.sh u-boot.image
Install pmOS the usual way to the SD card and then flash U-Boot on top of it:
$ dd if=u-boot.image of=/dev/mmcblkN bs=512 skip=1 seek=1
Display
Note II has two variants of the display panel. To find out which panel yours has, run dmesg | grep 'panel driver'
in TWRP or in a rooted Android shell (immediately after booting, otherwise the logs will have time to rotate and you won't see this message). Output should be similar to:
<6>[ 3.177303] lcd panel: ea8061 lcd panel driver has been probed.
In this example, ea8061
is the panel type. Other variants use the s6evr02
panel.
Partitions
This will vary between devices. |

TWRP
Only if you still have Android installed. Make sure to boot into recovery mode at least once after flashing it, otherwise it will be overwritten by the default recovery. |
Using Heimdall:
$ heimdall flash --RECOVERY TWRP.img --no-reboot
Downstream
S Pen
To get the S Pen working, you may need to do the following:
- Put the following lines to
/etc/udev/hwdb.d/60-evdev.hwdb
:
evdev:name:*e-pen* EVDEV_ABS_00=::300 EVDEV_ABS_01=::300
- Possibly update the hwdb:
$ sudo udevadm hwdb --update
- Restart the phone.

Recommendations
- Enable SWAP.
- Enable binfmt_misc (CONFIG_BINFMT_MISC).
Issues
- Currently, only S6EVR02 panel is available in the kernel package.
- The panel S6EVR02 is currently disabled. Expected to be enabled in the near future.
- Solution: Enable CONFIG_DRM_SAMSUNG_S6EVR02 in the config file.
- The display brightness is too high when the display turns on.
- Solution: Change the brightness so it changes to the correct value.
- The sound output is distorted.
- Note: It seems to be based on the cpu load.
- Headphone jack doesn't seem to work.
- USB OTG currently doesn't seem to work.
- Note: USB itself seems to work just fine. Note II is detected as "Netchip Technology, Inc. Linux-USB Ethernet/RNDIS Gadget" with
lsusb
command. Able to connect via SSH after adding required rule to nftables. - Note: External power to the USB device doesn't help.
