@gpatel-fr That´s perfect! Thank you very much for solving this stubborn problem. Now I can put the Pixel 3a into ‘Nokia 3210 mode’ with a single click. Calls and text messages work, and the battery lasts at least three days in this mode. #!/bin/bash # ==================================================================== # NOKIA 3210 MODUS: CPU throttling + All offline services (Pixel 3a) # ==================================================================== if [ "$EUID" -ne 0 ]; then echo "ERROR: Please run the script using: sudo $0" exit 1 fi echo "Enable Nokia 3210 mode..." # 1.

@gpatel-fr Using the installer won't work, it hangs on 'waiting for fastboot' because the device won't reboot. Not sure if that's related to the issue causing failure on OTA update though. I also get a 'device not supported' when the installer is detecting the device: [image: 1779724735779-screenshot-from-2026-05-25-16-54-17.png]

I wouldn't use a META product if there were alternatives. But there are a lot of people who are very resistant to change. There are groups for their kids' school activities: soccer, tennis, music, and so on. If you use Ubuntu Touch every day, a lightweight QML app like Greenline is perfect. You can check WhatsApp messages when needed. In an emergency, you can send a message like, “I'll be 10 minutes late.” Personally, I prefer a WhatsApp alternative that is fast and stable, uses few resources, and adapts well to changes in WhatsApp’s data structure—such as the Go library, whatsmeow, protobuf structures, and WebSocket conditions on the servers. I don’t need features like video or forms. If someone wants all of WhatsApp’s features (including META AI) on Ubuntu Touch, then they have the wrong device. Keep Greenline lean, efficient, and adaptable to changes at Meta for a long life on Ubuntu Touch. Many people and groups still need some time before they’re ready to switch to alternatives.

@Turbolqk said: @kugiigi I see, I haven't used UT in a few months, so I might've missed a few things. These things you think you might have missed have been implemented for years, so even the few months ago that you used UT last, you should have come across them.
