WhatsApp is stubborn about not installing to SD card. I have an unlocked bootloader, but have not rooted or installed a custom recovery yet. I am trying to avoid rooting because of SafetyNet, and because I need it pretty much only for force-moving WhatsApp (etc.) to an adopted SD card.
Since my bootloader is unlocked, is it not possible to:
- boot into custom recovery without flashing it
- create a flashable .zip containing WhatsApp
- instruct the installer to locate it in adopted storage, ignoring the app's
Why is it said that we need root for force moving apps, when the bootloader being unlocked should be enough? I don't have a problem with flashing a custom recovery, just ... why flash when one-time boot should be sufficient?
Likely I'm missing some limitations of
fastboot and the recovery here.
Edit: Trying out @DanHalli's answer gave me an error
