Prerequisites
In order to install postmarketOS on your device, you must have one of compatible devices in the list above and ability to boot at least into recovery mode.
Unlocked bootloader is not necessary unless stated otherwise on the respective device's page.
- U-Boot - bootloader.
- fusee-tools - extract BCT, SBK and pre-load U-Boot into RAM; nvflash included.
- re-crypt - re-partition TegraPT to make it usable with U-Boot and Linux overall.
Installation process
Step 0: Create backups
To enable nvp3server on ASUS Transformer devices with vendor locked bootloader, use BlobTools to extract bootloader (blob.EBT ) from the stock firmware and pre-load it with fusee-tools to your device in the APX mode.wheelie is not required in this case. |
If you have Google Nexus 7 (2012) or ASUS Transformer, backup partitions with nvflash. Refer to this (download files are here), this, and this guide for more details.
You should have a set of images (bricksafe.img
and other) which ensure that original bootloader and stock firmware can be restored. Additionally backup all valuable data from your device.
Step 1: Build and prepare U-Boot
Preferred source is the master branch of mainline U-Boot repo. U-Boot documentation contains most of stuff needed to prepare it to be flashed onto device as primary last stage bootloader and covers use of re-crypt.
In order to correctly use re-crypt you need to get SBK of your device. Fusée Gelée exploit in fusee-tools is used for this purpose. Refer to this section to get SBK of your device.
Step 2: Flash U-Boot
Once you get repart-block.bin
or split images from re-crypt it can be flashed using nvflash or using U-Boot fastboot interface. To check if U-Boot correctly boots on your device refer to this section of fusee-tools README to pre-load U-Boot into RAM. If everything works correctly you should flash processed U-Boot as described in board U-Boot documentation.
Step 3: Install postmarketOS
For devices with microSD available the preferred method of installation is flashing to microSD. In case of eMMC-only devices installation can be performed using pmbootstrap install --disk /dev/sdX
when exposing eMMC to the host with U-Boot.
There are also prebuilt images at https://images.postmarketos.org/bpo/edge/nvidia-tegra-armv7. Use xzcat xxxxxxxx-xxxx-postmarketOS-channel-ui-nvidia-tegra-armv7.img.xz | sudo dd of=/dev/sdX status=progress
. Where /dev/sdX
is the block device exposed by U-Boot. You can also flash with GUI tools like gnome-disks.
