solved it. completely... apparently this varient of the BW screen really wants the RZC chip removed. Wired directly to the 3rd pin spot and everything is good.

Not sure I could get any better with solid connections. Still no fix

i checked with the mod's via the wiki and got rid of the maroon wire and powered the vcc straight to the pin. still happening

It is a BW screen from Amazon with the 5v mod.

i figured out what was causing my issue. Wiring has been fine, per se. I did a trial and error and found my screen board is causing the issue. it still works with power straight from the pi, but not through the power boost. If I remove the screen power and ground from the power strip, pi gets power....

i noticed that when i don't have a battery plugged in, my powerboost will show the charge led and low led lit up. i saw in a post while searching the forums that he had a possible shorting issue. I followed your diagram and fixed up my soldering, and i'm still feeling a dead end. My powerboost light...

The pi.

My wiring.

Does anyone have any experience with pocketadventures.com?

I've seen the site, but there is little information about it otherwise

Basically the helders diagram you put. I plug into the pi, and everything powers up. Power from the powerboost and it's only the powerboost with power
