Cellular issues #13

Closed j1xlte-gtelwifiue closed 1 year ago

Sometimes the modem won't boot (solved with a restart or restoring an efs backup). Seems to be fixed, but BACKUP EFS ANYWAYS!

Followup for #3

SMS can be recieved properly, but sending reports as failed and yet sends four copies of the message to the recipient (so it didn't actually fail).

This is because RILD is looking for files created by Android's TelephonyProvider, which does not run on Ubuntu Touch. This RILD is not open-source, so not quite sure how to get around this. Copying the files from android seems to do something, but then RILD can't find /proc/net/xt_qtaguid (because it doesn't exist, even though it is enabled in the kernel config)
