Pine fun - Darling I bricked my internal storage

I somehow managed to brick my Manjaro distribution running on internal storage (eMMC) on my PinePhone. So, how do I re-install or install Genode in the future?

Turns out to be very easy:

  • Download SD card image of your choice

  • Download JumpDrive. JumpDrive is a small Linux setup that will export internal storage (eMMC) and external storage (SD card) as USB gadget mass storage devices

  • Flash JumpDrive on a SD card. Example

     unxz -c pine64-pinephone.img.xz | dd of=/dev/<sd-card-device> bs=1M conv=fsync

    (<sd-card-device>: We use a SD card to USB converter and pass it to our VirtualBox guest. For instructions on how to to do this please refer to the Sculpt documentation).

  • Connect the PinePhone's USB-C port to your machine

  • Insert SD card into PinePhone and boot from it. You should see the JumpDrive boot logo

  • The Sculpt report/log should say something like this

    usb 1-4: new high-speed USB device number 8 using xhci_hed
    usb 1-4: New USB device found, idVendor=1209, idProduct=4201
    usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
    usb 1-4: Product: PinePhone
    usb 1-4: Manufacturer: Pine64
    usb 1-4: SerialNumber: Jumpdrive
  • Pass usb 1-4 to VirtualBox

  • Load the g_mass_storage.ko kernel module within your guest Linux

     modprobe g_mass_storage
  • The log message output should show

  • Pinephone's internal storage is 32GB so

     unxz -c Manjaro-ARM-phosh-pinephone-beta24.img.xz | dd of=/dev/sdb bs=1M conv=fsync

    does the trick.

  • Reboot and have fun!
