PBP won't boot (no amber or green LED)

[ian-s-mcb]

Has anyone recovered from an unlit power LED state? I've seen plenty of posts with people fixing their amber LED boot problem, but this is different. Also, can somebody tell me what it looks like when PBP is in maskrom mode? Does the laptop screen display anything? Should the power LED light up?

Here is my situation:

While using a working Manjaro OS on my eMMC, I tried flashing my SPI. I used instructions on this wiki (https://wiki.pine64.org/index.php/Pinebook_Pro_SPI), but I may have followed it incorrectly, leading me to the broken state of my PBP.

Currently, the power LED on my PBP, which ordinarily shines amber then green, is unlit, but the red charging LED is lit when I plug in a charger.

I cannot boot using any of the following methods, which all were previously successful but now result in an unlit power LED:

• microSD Manjaro OS
  
• USB ARM Arch Linux OS
  
• eMMC Manjaro OS
  

I also tried booting with all bootable devices disconnected, but that too results in an unlit power LED.

I tried the two methods of booting into maskrom mode (the one involving recovery/reset buttons and the one with the two chip pins that need to be shorted), but rkdeveloptool outputs the same message: "not found any devices." I tried two machines with rkdeveloptool installed on and two USB cables, but still no luck.

I'm seriously wondering if my PBP is totally bricked
