I have been using the Signal android app on my Xperia X with SFOS3.4 for some years now. It was working mostly OK so fare until the last update a few days ago.
The latest update stopped working after restarting the device. Trying to start the signal app takes some time but eventually it will just disappear without opening.
I am now looking for a way forward without loosing my signal message history.
One options is to reinstall an older apk. but trying that from the file browser fails with the message “App not installed”. I guess it does not like to downgrade as I never had an issue installing a newer version.
- Does anyone know how to downgrade the APK from the command line?
- Does anyone know how to save/backup my data without being able to run the app?
- Does anyone have a solution to recover without data loss?
Any help, to recover is appreciated.
