Unfortunately this is sort of common for Manjaru to do this.  But if you keep up on incremental updates, it doesn't happen (as far as I know).

3 ways to recover from that,,,
unplug battery for some hours, perhaps a day
equivalently, press reset inside OR hold pwr button down, 20+ sec
I think you can figure which is easiest
Don't ever put a sd with an A64 OS in (and try to boot), or you will have to do this

But reading again, it (pbp) is not locked up
I assume your 16G armbian sd still boots???
Why not write tow boot to emmc,, use ONLY these not anything with spi in name

In the normal location, ie 64 sectors, 8M

This is most likely  a BUG in Tow-BOOT Display Driver.   which is why I can not install it at all presently.
I am able  to Install OS on emmc, so I'm fine there.  What held me back for many days was trying to get Tow-boot to work and that is not happening because of  this bug in display driver that boots with the Tow-Boot SPI.installer.

My SD cards all work, my SD Armbian works, I ever got  SD Postmarket to work, and SD Manjaro to work.
I'm able to install OS to  EMMC also  since I put both  Manjaro on there (which I broke on purpose yesterday deleting the UBOOT since that was one method from 1 poster in Tow-Boot issues and we wanted to try every  method posted in Tow-boot issues as well).  Then I installed Postmarket OS just fine using the Postmarket  Install  SD,  but that did not fix the issue either. 

After  many days of testing many different things with several  volunteers in  Pine64 Pinebook  chat room (discord)  and doing pretty much every possible thing except removing the SPI  chip and getting the same symptoms,  Screen would just  turn on Dark blue and no Tow boot Icon, no text, no error messages. 
It  turns out it's probably a Display bug in Tow-Boot affecting some  editions of Pinebook Pro.  Many people are having similar problems and reported it to  Issues ticket in  Tow-Boot also, I hope they are able to  release a new one with a fix for the display bug.

TL_Lim  was following  the attempted troubleshooting in  Pinebook Chat and said this last night:
[T] <tl_lim>  ...I suspect is tow-boot's display driver bug. From your description, your PBP indeed boot up from the tow-boot SD card and your observe the green status LED. My takes the LCD display driver that tow-boot using may not have correct LCD timing and cause some LCD display cannot lock the display team and this is why no display. I think someone already file such issue on tow-boot GitHub and hopefully this issue can be resolved soon by update LCD driver. I think your PBP SPI Flash is OK and no need to desold


The Troubleshooting  we did was pretty exhastive of every single  suggestion posted in Pine Forums and also things people did in  Tow-Boot Github Issues:

- wrote Tow-Boot..bin  to  SPI directly from inside Linux on PBPro  but when it boots, just see empty dark blue screen and nothing happens.  (this was attempted 10 times from inside 3 different Linux distros on PBPro).
- burned over 20 copies of  SD cards with tow-boot  SPI.Installer.Img in different ways and using different machines to make sure.  when booting with cards, got same dark blue screen with no words, no tow-boot icon, nothing.  It's an issue of Display,  I think it is indeed loading, but I can not see it becase of display driver bug.
- used over 8 different SD cards. (even ordered more from amazon, just to be sure but those did not change things)
- tried to write tow boot directly to SPI  from  2 different OS  (manjaro and  Postmarket) & also from SD armbian card boot.
- made  different versions of  Tow-Boot even older 2 older versions, non of them booted up
- made SD cards of spi.installer.img from inside linux and inside  windows Balena Etcher on different machines just to be sure the SD's were good. tested the SD cards also (not the problem).
-  all of them do same thing  when I boot up. Screen goes from Black  to  a Dark Blue ( means I have power)  and then  is empty, no  tow-boot icon, no text, nothing.  even if I spam  ESC key when hitting pwr button, nothing happens , no error messages either as some people see in Tow-Boot Issue tickets.
-  I even tried all the different advice from Tow-boot github issues.  one person showed how to delete the Uboot from Manjaro  with 2 lines of CLI.  I did that and it broke manjaro of course.  then  he  basically booted with SD with tow-boot SPI.installer and was able to see menu. This did not work, still just empty dark blue screen.
When I boot , I go from black screen (off)  to  dark blue screen I see if (a)  I load Tow-Boot...bin  into SPI  from inside OS.  it's like menu is invisible.
looks same if I use  any of  8 different SD cards  I made with spi.installer.img.
