3 days in, slow/stuck or no boot.

Whatever happens, do not give up hope.  I might be wrong but I seriously suspect that every serious PBP user has been through exactly what you're experiencing.

Thank you for the supportive responses, @wdt and @KC9UDX 
1. I've used Linux for approx 5 years on Windows or former Windows laptops. With respect to PBP, I flashed images for PBP on Windows on this older Lenovo Thinkpad and then I changed over to Debian. Used Etcher on both and Disks on Debian. Am not necessarily a Linux newbie, but am not a techie, either. Am not entirely sure that I flashed some software images well- that is, archiving, extracting etc. so that I will go over the Getting Started version of Pine64, again. https://pine64.org/documentation/Introdu...g_started/

2. I use Pine 64 store's USB adapter for emmc module and it seems to work well https://pine64.com/product/usb-adapter-for-emmc-module/ I  put pmOS on a new emmc module and put Armbian on the older emmc module and then changed and put pmOS on it because pmOS was the only OS/distro that seemed to work.

3. I use Sandisk Mobilemate+ reader and IOgear reader, usually in USB 2 port. Also, I use either Sandisk 32 G A1 sd card, Lexar 64 g or Kingston 32. Tow-boot is on a Transcend 8G card. For USB sticks, I found that Kingston or Sandisk worked.

4. I left the PBP battery unplugged overnight  and pressed recovery, power off for about a minute each, after trying Tow-boot, sd cards with pmOS. As well, I tried a few suggestions from this 2 year old thread specifically ayufan's uboot erase and uboot flash. Nothing worked. https://www.reddit.com/r/PINE64official/...r_good_or/  https://github.com/ayufan-rock64/linux-m...t/releases
Yes, I tried sds with emmc removed or turned off--- is turning it on really turning it off. I read somewhere on here that it is this way?-
Nothing worked and it is very disheartening. The red power light at the barrel port is on when plugged in with charger.
This is a lovely laptop and I wanted to use it with either Abiword or Libre Office, to watch videos (yes, I did so already and the display or screen is nice); listen to music on Elisa and some more and learn a bit more about Linux and such laptops.
Although I am aware it is nearly impossible to totally brick PBP, I am not sure what else to do. Thanks again.
