How to enter flash mode

Odin Mode: While turned off, hold POWER+HOME+Vol-

Fastboot: Hold Vol- while booting.

Installation

Download uboot from here:


https://github.com/novathor-mainline/u-boot


Flash while in Odin Mode:


heimdall flash --Kernel u-boot.bin


Setup postmarketos on PC:


pmbootstrap init

pmbootstrap install


Enter Fastboot mode, then flash kernel:


pmbootstrap flasher flash_kernel


And flash rootfs:


pmbootstrap flasher flash_rootfs


Reboot:


fastboot reboot

Installing recovery

samsung-codina uses weird proprietary Samsung boot format to boot recovery using the main kernel. u-boot can only boot recoveries that are in Android boot.img format. As a workaround, you can get vmlinuz from postmarketOS installation(do pmbootstrap export after pmbootstrap install), and create boot image with mkbootimg(using recovery CPIO).

Known bug
