First post here, let me know if I’m doing everything correct. I’ve googled how to do this to no avail and its so specific I thought it warranted a new topic.
What I’d like help doing is using titanium backup to restore my calendar data from a phone that died to a new phone which is the same model and operating system (should be simple right?). The only catch is that the google account on the new phone is different than on the old one (which is why I think it isn’t working). As the old phone is dead, I do not remember which google account I used (I usually generate a new one whenever I get a new phone just so google doesn’t accumulate TOO much data about me, although I’m open to better ways to do this… in a new topic I guess?)
Both phone specs (broken one might have slightly different software but not vastly different):
LG G4 (model LG-H811)
lineage OS 14.1-20171128-NIGHTLY-h811 (android 7.1.2)
Flashed (a while ago) with open gapps arm64 7.1-pico-20180130 and su 14.1 arm64
Stock calendar app, Build version 7.1.2
Latest (Aug 12, 2019) version of Titanium Backup Pro (TBP) from google play
What I’ve done so far:
-signed into google play store
-in TBP, Checked “menu>preferences>migrate system data” as well as “menu>preferences>restore app external data” and “menu>preferences>restoration settings>always associate to chose account”
-successfully restored contacts list and a few other things with titanium backup
-attempted to restore green TBP entry for “calendar storage 7.1.2” (data only, not app+data), get notification “data restore complete”
-shutdown and power up once, reboot once (just to be thorough, I think once would do it)
-Calendar data does not appear in app even after multiple TBP restores and reboots. Sometimes the calendar app asks me to sign into my google account.
Any help greatly appreciated, I have no idea what is supposed to happen next week haha. I need to solve this soon but also open to any other methods of automated, backup that don’t involve google (preferably also with encryption and auto upload to cloud but not required). Maybe a new topic for that also?
Also how do I tag this topic with helpdesk ? Did that do it? haha
-Just for everyone’s information - the tag “helpdesk” is disabled for (very) new users
-I found the username/password to the google account I used on the broken phone, clicked settings>add account (top right) in the calendar app, signed into old account, restored calendar data from TBP (yet again), rebooted and behold! Calendar data!
-In the future I will probably be moving over to the Simple Calendar. It has import/export feature, doesn’t look like it requires a google account, allows importing of birthdays/anniversaries from contacts (but doesn’t look like this is automatic) AND can show holidays from one of many countries of your choice.
Some questions that would still be nice to have answered if anyone knows:
-How is calendar data stored in android? Is it tied to a specific app or is there a system wide database? If a system wide database, does that data have to be associated with a specific google account?
-How can you tell which google account a TBP backup is associated with?
-Can that google account be changed before a restore?
