Due to a software bug in the pre-installed operating system on the PinePhone Pro, the bootloader ''U-Boot'' is booting into a boot loop if the battery is fully drained. In that case it is not possible to charge the phone. The battery can be charged by interrupting the boot loop by booting the PinePhone Pro into ''Maskrom mode'' or by charging the battery externally.

==== The installation is corrupted ====
The PinePhone Pro won't be able to boot if the installation on the SPI flash, the eMMC or the microSD card got corrupted. To boot a working operating system:
 
* Prepare a microSD card as explained in the section [[PinePhone Pro#Flashing to microSD card|Flashing to microSD card]]
* Remove any USB-C cable or device or add-on case from the PinePhone Pro
* Make sure the device is powered off by shortly removing the battery for a second
* Insert the microSD card into the top slot of the PinePhone Pro. Make sure the microSD card is inserted all the way and that the notch of the right side of the microSD card is not visible anymore.
* Power on the device while bypassing the SPI and eMMC as explained under [[PinePhone Pro#Boot order]]
 
The device should now boot from the microSD card. If the phone does not boot from the microSD card the microSD card was flashed with an incompatible image or the battery got drained as explained above.
