bricked it?

GPT part:  0, name:        IDBLoader, start:0x40, size:0x3fc0

no find partition:uboot.

I note the end of this there is the error saying it can't find partition 'uboot'... where there is a partition called 'U-Boot' in the GPT table... wrong name?

And I have to ask... you've double and triple checked you're using a PinebookPro image, not a Pinebook image?

Ameridroid sells both usb emmc adapters as well as sdcard emmc adapters (I have on of those--and it works very well).  I believe anywhere in the US  you would receive the item in a few days max.  Check out their web site . 

I find the adapter very helpful--I have a couple of other pine devices that use EMMC, too,  But especially in this case with the laptop,  if one messes things up through software,  it makes it easier to start over again with a fresh emmc install.  

Can you, however:
use the switch to turn off the EMMC, remove the EMMC and boot from a fresh manjaro sdcard build?   If so,  you haven't bricked anything. 
Also note that when reinstalling and reenabling the EMMC,  you may need to press the reset button for the EMMC to begin working again.

It's also possible to write the EMMC with the rkdeveloptool device in maskrom mode.  see http://opensource.rock-chips.com/wiki_Rockusb#Maskrom_mode
