Installation of Android/LittleKernel Bootloader

Maxnet did a complete install of Android on the device before started to port. It shouldn't be necessary to flash Android, because you will overwrite it with postmarketOS anyway. It shouldn't be necessary to install TWRP too, but is is very useful, so it is recommended.


You will need some tools for Installation:

Backup Data

Postmarketos is not ready to use as a daily driver yet. So use a phone you do not need for the development. If you have some data on it, back it up now.

Clean Firmware Install

Use the Windows Device Recovery Tool to install clean Firmware. This is to avoid errors and to gain the FFU-image.

Check you Storage

Open WPInternals with your phone connected to your Windows PC. Reboot it into flash mode, to get more information. There it says, from which manufacturer your storage is. If it is from Samsung, it can cause a brick of your phone. If not, you are good to go.

Unlock the bootloader

Now use WPInternals to unlock your bootloader. You will need an FFU-image for that. Use the Download page of WPInternals to download it.

Afterward, you need the Emergency Loaders. You can also download the needed files with the Download page.

Then you need the Engineering SBL3 files, which can be found here Now unlock the bootloader.

Connect your phone in mass storage mode

Use WindowsPhoneInternals to switch to the mass storage mode. It could be that you have to give the device a drive letter.

Backup your phone

Use the WindiskImager to Backup your phone (the MainOS Partition). Therefore select the Device, select a folder for your Backup and give it a name. Afterward, switch to Normal Mode again by holding down the volume down and power key together for 10 seconds.

Flash the LittleKernel Bootloader

To boot to Android you need to flash the LittleKernel of Android4Lumia. Therefore use the iflash tool.

Install the CustomROM

At the end of the process the device boots into the TWRP-recovery. Wipe all partitions to avoid errors. Afterward install the LineagesOS with ADB-Sideload. In TWRP got to Home > Advanced > sideload. Then use:

$ adb sideload <LineageOS.zip>

Replace <LineageOS.zip> with a path to the downloaded LineageOS-file.


If your device stays black but is connected as QSUSB_DLOAD, use the WindowsDeviceRecoveryTool to make a clean firmware install.

Kernel configuration

  • CONFIG_USB_G does not show up, but it is described as required for USB-Networking
  • CONFIG_PFT, CONFIG_USE_VFB and CONFIG_KINETO_GAN do not show up in menukonfig. This options should be disabled due to the Kernel configuration guide.
