@moncon got mine working to with the same instructions on Tmobile USA. having the same issues, can send sms but cannot receive them. Cannot send or receive mms either.

@hengyedev it just hangs or boot loops and tills me the software on your device is corrupt? I have been able to install lineage 17.1 on the device and sailfish os. Would a version of lineage os that is based on Android 9 work or does it have to be the Stock Android Rom?

Ok,Thanks @hengyedev , but unfortunately the emma tool does not support the l4293 model for the Xperia 10 Plus.

I have a Sony Xperia 10 Plus L4293 model and I have not been able to install Ubuntu Touch on my device. First issue is since I have unlocked the boot loader it appears emma will not present any roms for me to install on the phone.

2nd to that I appear to be having issues flashing 3rd party roms to the phone as well from sites like https://xperiastockrom.com/ and others.

Is there any way to forgo the Android 9 stock install and complete partitioning manually? I thought I read somewhere you need the stock rom in order to setup the proper phone partitions.

Thanks
