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.

The '''Explorer Edition''' comes with a modified U-Boot pointing to the microSD card pre-installed to the eMMC. The microSD card can be (temporarily) booted instead of the pre-installed operating system, when the power key is shortly held at boot. To always boot from the microSD card it is recommended to wipe U-Boot from the eMMC. When the pre-installed bootloader was overwritten with a bootloader without such a configuration, the ''RE'' button underneath the back cover of the phone can also be used to temporarily bypass the eMMC. The button may however only be pressed shortly for a few seconds during boot, otherwise the eMMC won't be initialized in the operating system.
==== Bypass the eMMC ====
===== PinePhone Pro: Explorer Edition =====
The '''Explorer Edition''' comes with a modified U-Boot pre-installed to the eMMC that lets you bypass the eMMC and boot off of the microSD card.  


The '''Developer Edition''', which was an earlier revision intended for development, was coming with an Android factory OS preinstalled. For details regarding how to remove the bootloader and the preinstalled OS of the eMMC for Developer Edition, please see the relevant wiki [[PinePhone Pro Developer Edition#Nuking the factory AOSP installation|article]]. The eMMC on the Developer Edition can be bypassed by shorting two specific contact points, please join the community chat for any questions regarding the process.
Ways to '''temporarily''' bypass the eMMC:
* Hold the power key at boot.
* There's a "RE" button underneath the back cover of the phone that can pressed shortly for a few seconds during boot.
** {{warning|If the button is pressed for too long the eMMC won't be initialized. This could matter if you're trying to boot into the microSD card to then install an operating system on the eMMC.}}
 
Ways to '''permanently''' bypass the eMMC:
* To always boot from the microSD card it is recommended to wipe U-Boot from the eMMC.
