first impressions and rooting
Hi,

hope this thread is the right place - I'm new to posting on xda developers (but been reading here sometimes for a long time).
I received my Cosmo on tuesday (2019-11-26).
Overall I'm happy with the device. The keyboard is good and I can actually touch type with it - obviously not as fast as on a full sized one. But Sometimes it misses characters, expecially the space bar.
The german layout is a bit awkward for umlauts. To Type "ä" you have to press "Fn+a", for "ü", "Fn+u" and so on. There is only one Fn key on the left side so fluid typing of especially "ü" and "ß" is difficult.
Software on the cover display feels like an early beta. Very slow and e.g. music controls don't work with all music players - but it has it's value for checking the time or answering calls (and seeing who's calling beforehand).
Battery life is pretty bad but surprisingly unaffected by usage.
... well, it's a low volume device so I'm ok with the downside. And I hope some will be fixed.
Planet computers promised to release officially rooted images and linux support etc.... it's not there yet.
But rooting was pretty straight forward:
  • activate "OEM unlocking" in developer settings
  • install magic manager
  • adb reboot bootloader
  • fastboot flashing unlock
  • reboot to bootloader again (not sure if necessary)
  • fastboot flash boot boot-magisk.img

(most people seem to use SP Flashtool, but it worked for me with fastboot which is open source)

I got the boot-magisk.img from here:
https://www.oesf.org/forum/index.php...dpost&p=292918
https://mega.nz/#!U8sFVACI!J-TS3q11H...1YIVDipez05BvE

When planet releases debian images I will try them out.

If you have any questions feel happy to ask.

Great
I was a little concerned when I got it yesterday.
Before powering on the first time I inserted a micro sd card.
Powered it on and it just said starting up for 39 mins
Ended up pulling the sd card out, now it works great.
Not sure what's up with that.

deadman96385 is supposedly working on TWRP and lineage os

What filesystem do you have on the sd card?
The Android version is missing some filesystem drivers e.g. exfat and ntfs.
I have 64GB sd card formatted with vfat(32) and it works withoud any problems.

Not sure it was likely exfat.

Muti-boot and Linux Cosmo support update
From email

Muti-boot and Linux Cosmo support update

In this update we would like to discuss plans regarding Linux support on the Cosmo Communicator.

With the Gemini PDA, Planet offered experienced users the ability to install Linux on the device, by connecting it to a desktop or laptop computer and flashing the device manually.

With the Cosmo Communicator we want to improve the user experience when installing a custom OS, such as Linux. To do that we upgraded two key components, the LK and the recovery mode.

The updated recovery mode can be used to partition the storage space of the Cosmo Communicator - see the option "Change the partition table of your COSMO" in the picture below.



This will allow the user to reserve space for the Linux operating system. As you can see in the picture below, there are currently 5 options:

1. Reserve all space for Android
2. Reserve 90GB for Android and 30GB for Linux
3. Reserve 60GB for Android and 60GB for Linux
4. Reserve 30GB for Android and 90 GB for Linux
5. Reserve all space for Linux



Once the storage for Linux has been reserved, you can install a custom OS on your Cosmo, by choosing the related option as in the picture.



This option will scan the microSD card for compatible installers and will present you with a menu showing the available installers as in the picture below.



Whenever new or updated custom operating systems will be available for the Cosmo, you will be able to download them into a micro SD card and install it in your device.

At the moment we have initial support for the following:

1. TWRP (Team Win Recovery Project)
2. Debian using KDE/Plasma
3. Debian using LXQT
4. Rooted Android


Once you select a custom OS you have to select where to install its boot firmware as shown below.

There will be 3 extra boot partitions that can host custom boot firmware.



Once you select the boot partition, the custom OS will be installed on your Cosmo Communicator. A boot menu will then appear when you turn ON the device, allowing you to choose what to start as in the following picture. The boot menu is integrated in the modified LK firmware.



Using this method you will be able to install a custom OS such as Linux on your device without the need for a laptop or a desktop computer. All you need to do is to download the installer in a micro SD card and use the recovery mode to start the installation.

Finally, a big thank you to our open source community (in particular to Sean, Adam and Nikita) which is working hard to get other operating systems supported on the Cosmo. In the following screenshot you can get a preview on what the community is working at the moment. We will provide a detailed Linux status update in the coming weeks. Stay tuned!














More from us this still this week. There will be another update later this week updating you on the over the air firmware update and Cosmo shipping.

Best regards,

Team Cosmo

First Cosmo Firmware update - this week!
from email
Quote:


This week, Planet will release the first Cosmo firmware update.

The latest Cosmo firmware includes new features and solves a number firmware issues reported by users:

1. New settings: switch OFF cover display on power down



This feature helps saving battery when Cosmo Communicator is powered down by switching OFF the cover display. When powered down in this way, you will only be able to switch on your Cosmo using the Esc key and charge your Cosmo using the left hand side USB-C port. We are looking at further power saving firmware possibilities

2. Fix for power charging indicator being on while the keyboard backlight is on.

3. The Duraspeed and Background Power Saving settings status is now OFF by default. This fixes the operation of many applications which were reported to be closing in the background when Duraspeed is ON. Some services were being closed down after some time of inactivity.

4. The eSIM chip status is now fixed after Cosmo restart, so eSIM selection is preserved (instead of switching to SIM lost 2)

5. Fix for Reject ringing call during another call from cover display

6. Fix for sending SMS reject call when two calls exist

7. Fix for Switch calls and merge calls from cover display

8. The Cover Display will now support the advertised landscape mode.

9. The Cover display will also support two font sizes for notification text.

10. Fix for icon sensitivity on top row of icons on the cover display

11. Optimisation for Contact list update on cover display

12. Some stability fixes for cover display


Cosmo Support Web Site

We have also started Cosmo support pages on support.planetcom.co.uk.

We will be updating these pages with more content in due course.
