downgrading to Android 10 to install Ubuntu Touch
-
Hi
I have gotten my hands on a OnePlus Nord N100 (BE83BA) that I was hoping to install UBports on, but unfortunately it has been "upgraded" to Android 11.
It seems the image in the UBports Installer is only compatible with Android 10, but I have difficulties figuring out how to downgrade it.
I did already unlock the OEM and enable ADB/USB-debugging but still cannot get root-access.
I am on Linux (debian) on my laptop, but it keeps saying that the .zip file with the downgrade cannot be transfered because it doesn't exist whenever I try to drag it to the device.
I did try to drag/drop via Windows as well, but that machine can't even see the root directory.
Please help me root this device.

@Lindisfarne You do not need to root the device.
OEM unlocking is not necessary at this stage.
You need a Windows PC (running Windows) and you need to download one of the Android ROMs on the devices page for that device, unzip it and find the MSM Download tool.
Please read here to understand how to use the Tool and take your time.
Once the tool has finished flashing, the device will reboot, then you can set up Android, unlock the bootloader , set up Android again and then install UT.
I have not got the MSM Download tool to run on Linux or in a Virtual Windows machine within Linux.
