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.
As far as I know, there is no way around making a backup. Titanium Backup may help with moving your apps, you’ll probably have to deal with other files with your favourite file manager.

If you want to change your ROM, you’re going to need to do it back up, there’s no way to get around that
The only secure phone operating systems are either grapheneOS or stock. All the others usually are behind security updates.
For migration, I would just use a USB C drive and transfer files.
Uhm, not necessarily. First of all, aosp should get security updates at the same time as graphene (or earlier, which is more likely); then there are non-pixel phones (yuck, I know) that aren’t supported by graphene guys, and when those go eol, custom roms often keep pushing [software] security updates for some time at least (source: this message is sent from a 1+5t running DivestOS based on android 13); finally, stock roms may arguably ('cause vendors introduce bloatware, which can potentially be used in ways not intended by its developers) be more secure, but they suck at privacy department in like 99 of 100 cases
AOSP does get security updates first because GrapheneOS is based on unmodified AOSP. They are quick to port over updates though and they have extra features like hardened malloc and better user profile support.
Non pixel phones aren’t secure because GrapheneOS doesn’t support them. They aren’t secure because they either don’t have secure elements, broken verified boot, or don’t properly support alternative operating systems. This makes phones like OnePlus, Fairphone, etc not secure enough for GrapheneOS.
DivestOS I would say is the least worst option when it comes to supporting EoL phones. They’re at least honest about what they do and don’t provide unlike what other OSes do. On their website, they tell you they aren’t a secure OS and they can only try their best to reduce harm on an EoL device. DivestOS Security.
Pretty much agreed. Although, onepluses used to be quite good before they decided to stop allowing setting custom vb keys.
What I wanted to say is that security is a spectrum, and stock roms aren’t necessarily the best.
P.s. other roms sometimes use stuff like hardened malloc as well (ik that its developed by graphene, tho) yet none (except graphene itself, ofc) I’ve personally tested have storage (and as of recently cobtact) scopes which is quite sad.
I fear that everything around custom ROMs and data security comes around as tedious;) Creating backups may be one of the less bad ones tho
Lol, so true.
No two phone setups have had the same process. Similar, but not the same.
I’ve written Project plans to ensure nothing gets missed. It’s nuts.
I use DivestOS which is based on LineageOS and these have SeedVault integrated in it as a backup solution, but since it doesn’t work well I’ll tell what I do (If your OS has Google’s backup solution, it works well to a certain extent, but there are times when it cannot restore things like call log/sms even though it backs them up).
- I backup apps, SMS/MMS and call logs with Swift Backup
- Since I don’t have many applications, I examine each application one by one to see which data can be transferred and in what way.
- I backup data of the apps like Aegis, NewPipe etc. to their respective
Android/mediafolder, which means I basically export Aegis’ backup file into/storage/emulated/0/Android/media/com.beemdevelopment.aegis/backups, with this way, I can back up and restore themediaalong with the APK of the application using Swift Backup. If you find this step unnecessary/complicated, you can create a folder calledBackupsanywhere and put all your backup files there.
- I backup files and folders with Syncthing, it basically sync’s 2 directories between 2 devices and I sync all my folders into my PC with some ignore rules (for example, to avoid synchronizing the
.thumbnailsfolder unnecessarily). Also if you stashed all your backups/exports into some folder, it will also sync. - Technically there is no need for a non-APK backup for applications that have their own cloud based backup mechanism or are cloud-based.
When I take these backups, I can completely restore the phone to its previous state even after factory settings. Of course, for a cleaner start, sometimes I don’t sync some folders back or don’t reinstall some applications. To do this the way I want, I reinstall and restore data of the applications one by one.
that’s all great, but Swift Backup requires you to have a rooted device first.
I does not require it. I don’t have root.
I’m skimming this thread but, uh
⚠️ Root required for backup & restore
- I backup apps, SMS/MMS and call logs with Swift Backup
You could root your OS and get a full backup. Otherwise, ADB (which doesnt backup app apks iirc)
Unless the bootloader is already unlocked you won’t be able to root without a factory reset first. It’s a security feature, though an annoying one.
For my non-rooted phones, I use SMS Backup & Restore to backup SMS/MMS. It runs on a schedule.
I also use
to keep all my personal data (such as SMS Backup, downloads, whatever) synchronized to a desktop at home, which has its own backup service.
I also use Syncthing to keep all photos synced to my laptop, so I can easily review and manage them (I have it set so changes/moves/deletions sync back to the phone).
