How can boot from MicroSD after replacement of the main board - u-kidjp - 11-03-2024
I just got a new main board of the PPP and replaced it from old broken one.
After replacement of the main board, my PPP only boots into AOSP android after displaying "Rockchip kernel" splash.
I tried with powering on with volume-down button, couldn't boot. With volume-up button, it goes into the android recovery mode,
I also tried with RE-button, but I got no response.
Is there any way to boot from MicroSD?

I would start with finding out what Bootloader is on your SPI.

From Android OS?.

Are you sure you have a PinePhonePro?
I do not know everything, but the only android I know of is for the original PinePhone.

rough plan:
prepare tow-boot installer into sdcard.
use RE-button to boot that sdcard.
optional, wipe spi mem.
install tow-boot into spi mem.
prepare distro to a sdcard, could be same sdcard.
boot using volume down button from sdcard.
alternate plan:
prepare tow-boot installer into sdcard.
use RE-button to boot that sdcard.
optional, wipe spi mem.
install tow-boot into spi mem.
boot using volume up into mass mem mode.
optional, wipe internal mem.
option a, install distro into internal mem.
option b, install distro into sdcard mem, sdcard needs to be inserted.
if spi is empty or wiped, then phone boots from internal memory first.

Yes, PinePhonePro.
Android status says, Device Name rk-3399-mid, Device Storage Size = 128GB. These are compatible with PPP, no PP.

Thanks, I tried tow-boot installer with RE button once again and it seems to be finished successfully.
(but, android don't boot any more)
I will try to install Manjaro or Mobian.
