Rooting the Cosmo Communicator

The process above works also for V23.

Just extract boot image with Sp_flashtool, patch with magisk and then install using fastboot.

Hi All, I'm new here and want to thank all for posting here. It helped me a lot. I managed to unlock the bootloader, install Debian and rooted Android.

Now I want to start installing Devuan Linux inside Android (reference topic on this site from jjrv). It states:

"Unlock bootloader, install Magisk and Get Ninji's rooted boot image and flash it". Image only suitable for V19 and then continues..

Now my question: Is the rooted Android provided by PC (V23) different than the custom images (like Ninji's) and still needs to be flashed? Or has the rooted Android boot the same functionality (as it is rooted already)? If so, I can continue the installation provided by jjrv. If not, do I need to flash the boot image provided by ZimbiX for V23?

Thanks in advance.

My understanding is that
1) Planet's own images are signed, so no need to unlock bootloader, however
2) Planet's own images are built for their partition scheme, where you need to set up partitions like 90/30 Android/Linux - even if you are interested in just using the rooted Android, because you don't even get the "rooted android" partition without using *some* scheme where a bit of space is allocated for Linux

The multiple partitions approach do allow you to boot to unrooted android since it's preserved.
The problem is that Planet's bootloader does not seem to allow you to set the "default" boot partition. So you always have to manually select that you want root...

Thanks for your reply Zarhan,

That makes it clear.. I don't have to flash an other boot image again, as PC's rooted image is suitable enough now.

I can do a normal boot to install OTA's and yeah, I have to select rooted Android with each reboot, but I don't find that a problem at all..

So now I'm going to struggle to get the Devuan Linux to work..

As I saw you already did this.. If you have any additional tips on top of the instructions of jjrv, it is much appreciated.. : )

Not really - I've commented on that thread with my own additions.

Ah.. ok. Thanks.. I'm going to try after I receive my ordered 512GB SD card. Will update later on the right thread of jjrv.

Have a good day..
