Porting Ubuntu Touch to Motorola Moto E 2020 (ginna).

@arjune Maybe you can get some help through this Telegram group:

@arjune Don't use the halium-install script. Use only the commands at the end of the standalone kernel method.
Build:

./build.sh -b workdir
./build/prepare-fake-ota.sh out/device_genia_usrmerge.tar.xz ota
./build/system-image-from-ota.sh ota/ubuntu_command images

Install:
Flash boot.img to boot partition.
If you have systempart in your cmdline flash system.img to system, otherwise push rootfs.img to data partition as ubuntu.img.

As stanwood said, the telegram porting group is more active.

@ikoz so just dont use the halium installer and just flash and then just boot and it'll work????? (oh and TWRP says that boot.img is larger than target device)

ikoz

@arjune Yes, just flashing the 2 partitions is enough. Also, boot.img can be flashed in either bootloader or fastbootd mode, while system.img only on fastbootd (it is a sparse image).

TWRP says that boot.img is larger than target device

It should be flashed with fastboot flash boot boot.img, make sure deviceinfo_bootimg_partition_size is set correctly. TWRP is the recovery, I don't get how it is involved.

@ikoz ok I did those, now do I just boot and it will boot into ubuntu touch? (I flashed the boot partition as boot.img and renamed rootfs.img to ubuntu.img, and moved the ubuntu.img to the data folder. Is that what I was supposed to do)?

ikoz

@arjune Yes, and make sure that /data is formatted to ext4 (with fastboot format:ext4 userdata) and mounted when you pushed it.

Be aware that the device will probably fail to boot on first try.

arjune

@ikoz bootloop

arjune

am I supposed to put the ONE FILE (ubuntu.img) in the data folder or do I flash the image?

Was /data mounted correctly when you pushed the rootfs? Did you format userdata? Also, you seem to have overlaystore enabled but overlayfs in kernel is not enabled (unless I missed something).

Anyway, it is better for you to ask in t.me/ubports_porting, there are more knowledgeable than me people there that can help you, and real-time communication is preferred because porting can take a long time to succeed.
