Hi everyone. I have a Samsung S20 FE running LineageOS 23 (Android 16). I’d like to disable the Wireless Emergency Alerts service. The plan is to run:

adb shell
pm disable com.android.cellbroadcastreceiver.module

Questions:

Is it safe to disable this module this way?

Will the phone go into a bootloop after the next reboot?

Does anyone have verified information or real experience with this on the S20 FE / LineageOS 23 (a-16)?

I want to automate the installation of ubuntu-desktop v24.04 hybrid.iso using autoinstall.yaml. I found that the steps for this are described here: https://danielpersson.dev/2023/08/07/looki-looki-no-hands-automatic-install-of-ubuntu-server/

After making the necessary changes and repacking the ISO, I ran into a problem:

• when flashing the image with balenaEtcher, it shows an error that the partition table is missing;
• if I still write the new image to a USB stick, it doesn’t contain an MBR/GPT partition table and therefore won’t boot on a PC.

My question is: what am I doing wrong? Do I need to manually specify the partition table when repacking the ISO, or is the cause something else?

Thank you in advance)
