Samsung Galaxy Note II (samsung-t03g)
WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) pmaports#599 has been considering dropping it. The processor of the device may support the armv7 architecture. If so, you can modify the device package and change the architecture accordingly. |

Basic info
What works
- Compiling the kernel
- Flashing with Heimdall
- Booting initramfs
- SSH
- Touch screen fully calibrated
What does not work
- Sound
- Weston
Not tested
- WiFi (needs kernel modules compiling first)
How to enter flash mode
Press and hold "volume down + home + power" simultaneously. Then click volume up to confirm.
Installing system
The device package and kernel is now available, pre-built, from the repositories.
You can install the OS to an SD card or your system partition. I've only tried an SD card:
$ pmbootstrap install --sdcard=/dev/sdb
You will need a 1GB SD card in order for this to work, also keep in mind that this will format the sd card.
Please also note, that you cannot flash directly to the system due to an error in Heimdall.
Next you want to put your phone in download mode by holding power + vol down + home
all together until you enter download mode, press volume up again to continue past the warning.
Now you can flash the boot image:
$ pmbootstrap flasher flash_kernel
We're using flash_kernel
because the N7100 packages its kernel and initfs file into one boot image, where as some other phones have separate partitions for each unlike the N7100.
If everything checks out OK, your N7100 should reboot and you should see the Samsung logo. Dont worry if the screen is flashing on and off and its taking a while, after a minute or 2 it should show up the pmOS splash!
Issues
- Weston does not run, presumably because of missing API calls. This should be fixed once the device runs mainline.
- The kernel seems to have a bug which causes it to reboot a large number of times. It will eventually be able to boot properly though. ([1])
Mainline Kernel
There is currently no mainline kernel available but it should be possible to mainline this device. Have a look at Midas on Mainline for work on mainlining very similar devices.
Work to create a DTS for this device can be found here: [2]
The n710x upstream DTS is here: [3]
Replicant is interested in further mainlining this device and replacing the bootloader with u-boot and would like to collaborate with us [4].
This device's Qualcomm Gobi MDM9615 Modem seems to have some mainline kernel support: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/clk/qcom/gcc-mdm9615.c?h=v5.2.7
