Huawei Y360-U61 (huawei-y360-u61)

TWRP
Clone this Git repo: https://gitlab.com/eloydegen/huawei-y360-recovery

Use the TWRP from the repo above, because it is not upstreamed.

It could probably be installed using Linux, but it has been tested using the SP Flash Tool running on Windows. A "Scatter file" (txt file of a partition scheme) is needed, determines the offset that TWRP should be flashed to. Get a copy of that file here.

Fill in the key and scatter file in the SP Flash Tool. Set a checkbox on the recovery partition and browse to the TWRP file.

Turn of the phone, connect it and click on "download", a green check should appear after a while.

Enter TWRP by pushing Vol Up + Power, then navigate to recovery.

Installation
It isn't yet upstreamed into postmarketOS. Kernel copy can be found here: https://gitlab.com/eloydegen/huawei-y360-kernel

Mainline
It seems there is some support for this SoC, but only UART according to kernel documentation.

Misc info

 * mediatek flash tool might work for this SoC too, not tested yet.
