The Volla 22 (Gigaset GS5) Thread

This thread if for discussing the Volla 22 port and for me to post progress. If anyone want to test things, give me a shout and i’ll get you a test build and instructions.

Current progress is pretty good.Ive made calls, used mobile data, taken pictures, used wifi. Still some things to iron out before I make a more public test build though.


The current state is approximately, everything working except:
Video recording causes crash


The video recordong issue seems to be present on all aarch64 devices and SFOS 4.4, like my 10 III

It should… My understanding is the Volla 22 is a re-branded GS5

Ahoj Mr. piggz i would Test it on my Rephone…Please Install Instruction


Here is the first somewhat complete image. Pipeline · sailfishos-porters-ci / Halium Mimameid Ci · GitLab . Still development, so no complaining. Extract, run “sudo sh” and put the phone into fastboot mode. If it is the same product name, it will flash, if not, its up to you if you want to edit the product name in the script and try and flash it anyway.


Update of halium-android-rootfs (mostly) fixes video playback issues. Can be fetched with a zypper ref/dup.


Ok, the install works on a GS5 (128 GB version - GS5CTNB02845) with no issues. Ran the update and so far so good. Video recording didn’t work.

  • wlan/browser
  • fingerprint
  • camera stills
  • audio recording
  • bluetooth transfers in both directions.

Hello Mr.Poetaster

to flash sailfish on GS5 (bootloader must be open?)
I put the gs5 in fastboot mode and run the command “sudo sh” in terminal ???
i this way ok?

Thanks Mr.

Did you zypper dup to try and fix the video recording?

After you set up developer mode in android, you reboot to fastboot (vol. + volume up) and then run ‘fastboot flashing unlock’. After that you can run the script.

Yes I did. But, I’ll take a look if I missed something.

Thanks Mr.Poetaster :+1:

After updating to Sailfish can i flash back to android?

If it’s unlocked, sure. It’s more complicated to flash android, though.
