My pbp is a sleek, black, flat brick, and won't boot from any kind of media

My experience for what it's worth:
I went through all the suggested fixes (described in a previous post: flashing zeros to SPI, checking daughterboard cable, etc) and finally started over. I had tried so many approaches, that I was losing track. I used a second computer, a 2gb HP celeron laptop running puppy Easy OS on a usb stick.
I disabled the 64gb emmc and removed it. I had already flashed the SPI with zeros. That left only the sd slot for booting.
I downloaded balena-Etcher on the HP, unzipped it, and changed permissions to allow execution. I downloaded the Manjaro ARM KDE plasma... 21.06 . I put a 32gb Kingston HC1 "Canvas" sd into a usb multipurpose reader from IOGear Model GRR304SD and put  reader into a USB 2.0 port. I used Etcher to flash the 21.06 file onto the sd card.  After the file was flashed (5 min), Etcher ran a validation check which failed. I redid the flashing, and the validation check said the flashed image was fine.
So, I loaded the Kingston sd card into the bare bones PBP, held the power switch down for a minute, clicked the tiny reset button on the motherboard, pushed the power switch for a few seconds, AND, for the first time in two weeks, the PBP lit up and went into action.
One down, one to go.
I removed the sd card, enabled the emmc ,  pushed the power switch and got nothing. So:
I loaded the emmc card on to an Ordroid USBEEMMC (Olympian LED) reader that I bought for the purpose, and put it into the 3.0 USB port on the HP. When mounted, I looked at some of the files and found that I had previously flashed the Manjaro KDE plasma...21.07 file, the one meant for intel machines.  Using Etcher again, I flashed the  ARM 21.06 file that  worked on the sd card.
I reinserted the emmc card in the PBP, and it worked fine.  Put the sd card in as well; and that worked.
So, it was all my stupidity. I highly recommend Etcher, the Ordroid USB-Emmc reader, and the IOgear USB reader. I used the pricier sd cards to be safe. If I have trouble in the future, I would not flash zeros to the SPI  until every other option failed. It took me days to do and I'm not sure that it was needed.
Loving my PBP.


This is another NOOB who was reading your problem trying to solve mine.  This post did it!  A simple problem that looked like I was going to have to pop the back and get tools, etc.  I put the wrong OS on my SD card!!!!!   That is why it would not boot.  Sometimes - maybe most of the times - it can be the simple things that mess us up. Especially me.
