On the '''PinePhone Pro''' the '''eMMC''' (the internal storage of the phone) has a '''''higher boot priority''''' than the '''microSD card''' (see [[RK3399 boot sequence#Boot sequence details | RK3399 boot sequence details]]). That behavior is in contrast to the original '''PinePhone''' with the Allwinner A64 SoC, where the '''microSD card''' has a '''''higher boot priority''''' than the internal storage.

==== Bypassing the eMMC ====
The pre-installed bootloader of the operating system the '''Explorer Edition''' came with can boot the microSD card when holding the power button at boot for a few seconds. If that doesn't work (because for example the bootloader got corrupted or is configured otherwise in a new installation) the eMMC can '''always''' be temporarily bypassed at boot to be able to boot from microSD card:
On the '''Explorer Edition''' hold the ''RE'' button underneath the cover for a few seconds, while powering on the device (holding it too long will cause the eMMC to not get initialized after the boot).
On the '''Developer Edition''' short the eMMC bypass contacts while booting.
For details see the section [[PinePhone Pro#Boot order|boot order]].
