Should I wipe bootloader on eMMC ?

I think the Explorer Edition does not have SPI storage.
Therefore I am not sure if this works yet, but maybe others can update me on that?


I have PPP EE, running Tow Boot WIP4 from the SPI.
I've had an unbootable manjaro on emmc due to the corrupted kernel image file after an update, installed Tow Boot without any problem using RE button.

Somehow that doesn't work for me.
I have flashed the SPI image to the microSD with: 

sudo dd if=spi.installer.img of=/dev/mmcblk0 bs=1M oflag=direct,sync status=progress

and then keeping the RE button pressed whilst pressing the power button, gives me a red light in the top left corner of the phone followed by a yellow light.
The next thing is that manjaro starts up.

1. "of=/dev/mmcblk0", are you sure this is the right device? It's usually /dev/sdX on a PC and /dev/mmcblk1 on the PPP.
2. I've used the following procedure: hold power button for a few seconds with battery removed, then install battery, then hold the RE button pressed and plug in the power cable.

Well The thing is , tow-boot boot the emmc first , so if you have tow-boot spi-installer on the SD , then the phone will read it and still boot from emmc .... you need to HOLD volume down to boot the SD card , so if you have an OS on the emmc the procedure is as follow

1.Power off the phone
2.Power it on holding RE for a couple sec
3. on the Red light HOLD volume down to boot SD card (should have light blue light instead of yellow)
4. ready to install !

Thanks for that, it got me to install tow-boot on SPI. I was a bit disappointed to find out that there is not yet a way to install postmarketos on the emmc. Currently I have the shipped manjaro on my emmc. Guess I have to wait until jumpdrive becomes available for the ppp. Please let me know if there is anyone who knows how to get pmos on the emmc without jumpdrive. Cheers!

See post 15 above for Tow-boot "version" of jumpdrive.

I have flashed the latest release (2021.10-004) of Tow-Boot to SPI on my PPP yesterday.
However I am now unable to boot Mobian from the SD card.
So far I have tried the Mobian PPP image (which I believe to be the wrong one for Tow-Boot?) and the efi image. Both the latest weekly version 20220306.

When holding the volume down button while booting the LED gets first red and then blue. It stays blue and does nothing until I shut the phone down.
The same happens when I hold the volume up button. According to the documentation the color should be blue for volume up and "aqua" for volume down, however I see no difference.

The preinstalled Manjaro boots fine from internal storage when I don't press the volume keys during boot.

What am I doing wrong?

My guess is a bad flash onto your SDcard, or corrupt download.
You should be using this image.

I have already flashed it twice but will try downloading it again.

Forcing boot from SD card by holding the volume down key does not work on my PinePhone Pro Explorer Edition.
I wiped the internal storage and now Tow Boot boots from the SD card.
