Switching to custom rom on android device with data (infosec.pub)

submitted 1 year ago by [email protected] to c/[email protected]

Hello all,

Currently I am debating whether or not to switch to a (preferably private/secure) custom rom on my device, however said device had been in use for a while now.

My question is the following: For those who have been in this situation, how have you dealt with the existing data on the device in terms of migration? After all, switching ROM usually involves a factory reset. Creating backups of everything is a bit tedious and timeconsuming and there is always the possibility of forgetting something.

Yes, I wish you had quoted the entire text.

Data

The private app data in /data/data/ or /data/user/*/ that stores your app preferences, login info, databases, etc. This is the most important part to restore apps potentially with their state preserved.

Requirements:

⚠️ Root required for backup & restore

⚠️ Shizuku mode (ADB access) cannot read/write at these path

Nowhere in my instructions did I say that I used this feature (“backing up app data”) or that it should be used. You do not need root to backup SMS/MMS & call logs & APKs & external data (Android/data) / expansion (Android/obb) / media (Android/media) of the apps installed… I have also stated many times that I use the in-app backup/export method for application data.

Right sure, but everyone else uses backups for the app data. I can install apps in a couple minutes, but the data takes ages, if the app even offers a built-in ability at all. It'd be like saying 'I have backups' but just of your computers operating system and programs, but no personal documents or data. It's technically a backup, and it's useful for someone with some use-case, but it's not the general definition of a 'backup'.

To quote your quote of my quote:

This is the most important part to restore apps

I have also stated that I am "skimming this thread", so getting all defensive is hilarious.
