Hi friends,
I decided to install manjaro xfce on my Pinebook,and after a quick review of websites and wiki pages,I have realized that the device boots surely from a SD,maybe
there are different procedures,but the straightforward one is the SD...But how can I write the image to MMC? I tried to write the image from an USB drive to MMC using dd from a live OS brought through the SD...Something has gone wrong and my device can't power on...I love this device and the underlying idea,can someone please give me an hint?...

Couple of questions that might help shed some light and help other members narrow down how to get your PBP back up and running:
What was the command you used to write the img from the sd file storage to the emmc?
did you unzip/tarball the img?
if you put your live os sd back into the PBP does it boot to the live os?
when you try to power on the PBP do you see any of the lights? (should at least see the red LED)

If, perhaps, you used an image for pinebook vrs pinebookPRO,
then this is expected (these devices have different cpus and different uboots)
Try a long press, press/hold pwr button +20 s, then regular 1s press
If uboot has been written to emmc you will have to remove/disable the emmc
This has happened to me, 2y ago or so

I am assuming that you get NO leds except charge?

I'm on same situation.
My pbp is dead. Nothing led, but still hot pbc and nvme.
I had problems with nvme on past so I decide to change battery and quit nvme.
I can't start pbp. No leds. Pressing a log time powerbutton. A sd card with manjaro created by balena etcher inside.
I have usb serial adapter but I don't have fuck idea how to use it...

Maybe you have wrong uboot on emmc,,,pinebook has WRONG uboot, you want pinebookPRO
right uboot will have idbloader signature at 64 sectors, 32K,, as so
3b 8c dc fc be 9f 9d 51
take uSD card you tried to install,,,, dd if=/dev/sd of=test skip=64 count=1 (/dev/sd is whatever sd card shows up as in working computer)
then hexdump -C -n 16 test ,,, this will show if you tried to install wrong uboot (if you don't use -C the bytes will be reversed ie 8c3b ...)
if the wrong uboot is on emmc, then it must be removed/disabled, then a long press(20+s) will work
otherwise, the wrong uboot will just be loaded again
OR maybe the hardware is bad
----
also it is easy to confuse arm64 with amd64, obviously the latter is for x86 computer, well 64 bit
I'll tried all methods to boot explained on forum and my pinebook pro doesn't boot.
I have problems with nvme disk, too hot and makes freeze cpu. So I disconnected it. I see battery was expanded and I quit it.
Trying to connect cables to bypass battery, doesnt run. Perhaps I burned the soc.
I tried manjaro and netbsd sdcard to boot. Quitting emmc and nvme all posible combinations.... Nothing!
So I cant boot my pinebook pro...
Any suggestions?
So you've removed the eMMC and NVMe adaptor, and can't boot from Micro SD card?
There are only four possible things left;
1 The CPU is locked. If you have removed the battery and disconnected power that should solve this. Else, I think you have to hold the power button for 30 seconds.
2 Something is running from SPI ROM. You'll have to disable the ROM.
3 For some reason the micro SD cards you are making are not bootable. If you are using the correct NetBSD image, for the Pinebook Pro (not Pinebook) then as long as you are writing the image correctly and have a good SD card; it should work.
4 The hardware has failed. This is fairly unlikely.

From the wiki:
Quote:Even if you need to recover from a defective bootloader written to the SPI flash, you can simply short pin 6 of the SPI flash to GND and boot. This will render the SoC bootrom unable to read from the SPI flash and have it fall back to reading the bootloader from other boot media like the eMMC or Micro SD card.

There is more than 1 way to skin a cat
There is a button, to short pin 6, the SPI clock (to gnd)
THIS BUTTON IS NOT RELIABLE
this button is located near the hard reset button
you can check if it is working by measuring R between pin 6 and gnd
with the button pressed and button not pressed
3 hands, either with assistant or a good jumper ,, gnd plane to meter probe
if there is no difference in R, then you have to do manual short (do wiggle the button when pressed if necessary, might help)
