Restoring Pixel 6a to factory and keep data

angeloweb

Daughter's going off to college. Got her a pixel 6a and put grapheneos on it. Visual Voicemail will not work, and she needs it. So looking at moving it back to stock os, without losing her texts, contacts, & pictures. Not sure if using the web installer can take it back from graphenos and keep the data intact and usable?
Any insight or directions, please?
Thanks

angeloweb You can't switch OSs without wiping the device - this is a fundamental security feature.

I think you want an app called "SMS Import/Export" - export; store the file off the device you will be wiping; wipe; install; restore the file & install the app; import.

Importing should be done with all networks disabled, because you need to temporarily set SMS I/E as the system SMS app, and it doesn't receive SMS well.

This can do SMS, MMS, and contacts - not other messages. Edit: You will need to do photos manually.

angeloweb Visual Voicemail will not work

Have you had a chance to read over the usage guide's carrier functionality section.

If you are having issues with Visual Voicemail, please be aware that AT&T USA users are unable to use this feature currently due to a lack of AOSP support. Other carriers are done on a best effort basis. We would suggest using Google Dialer with sandboxed Google Play if you are unable to get this feature working.

Additionally, perhaps this may help as well - Visual voicemail support

No. Please read replacing GrapheneOS with the stock OS
However, there maybe several methods to do that, one of which would be to use a Google account to back up the contacts, messages and photos.
