I’m ready to debloat (with universal-android-debloater), but before I do that Id like to backup the OS in the device to my computer.
If I want to backup with the stock ROM, Im redirected to a commercial service Im not going to use.
If I want to backup with twrp, it won’t let me backup via usb cable to the computer.
There must be a way to backup from the computer to the computer via usb, correct?
ETA: Can I backup with universal-android-debloater?
What do you want to back up exactly?
You can backup all your saved stored data if you want like pictures, music, downloaded items, etc. You can use ADB for that.
But the installed apps? Why bother?
Just download the latest official ROM for your device from the manufacturer. If anything goes bad, you can reinstall the ROM.
