Cosmo Communicator - Android / Rooted Android issues

« Last post by CJ_Sucks_at_Life on December 08, 2025, 10:26:46 am »

I have been trying to get something proper running on this for a good while. Debian is out of date to massive degrees and most other linux's (ubports etc) are held back by the proprietary kernel.

I tried installing rooted android on the v3 pipeline. However whenever I install it through recovery mode. It boots and installs the option on the screen. However booting into the android install doesn't have a magisk installed to properly finish it. and Using a up to date magisk causes the boot screen to complain about "unverified boot". and just put me back in a distro where root is only half installed.

Would anyone be able to direct me to a proper up to date guide or help me with this issue?

Cosmo Communicator - Android / Re: Android Recovery missing partition and custom OS options?

« Last post by theGreedyGoblin on December 07, 2025, 12:34:36 pm »

it appears that the firmware for the codi now works, however i do not fully know what fixed this. The initial issue was that the firmware was an unrecognised version, and subsequently trying to update it appeared to fail, however seemingly by random the next day the codi was working again. im completely lost for why this could be the case but regardless this has left me with more questions than answers. However, my cosmo appears to work fine now, thank you for the advice.

Hi,

have you tried flashing with both 'Aeroplane mode' and 'Do not disturb' ON? What error does the CoDi Assistant return?

Cosmo Communicator - Android / Android Recovery missing partition and custom OS options?

« Last post by theGreedyGoblin on November 23, 2025, 09:00:11 pm »

I am using a recently bought second hand cosmo communicator which has since been factory reset. When trying to update the android firmware outlined at https://support.planetcom.co.uk/index.php/Cosmo_Android_Firmware_Manual_Installation I have the issue that the recovery mode in which the "Change the partition table of your COSMO" and "Install Custom OS on your COSMO" options are entirely ommited.

Ive so far ruled out the SD card being the issue as ive tried multiple of varying capacity.
Ive tried every provided version of android including 19, 22, and 23.
Ive also tried installing linux only to encounter the same issue.
Possibly worth noting is that the text under the android character just before the recovery screen is in japanese despite the system language being set to english and having a US keyboard.

I am fairly unfamilar with android and am hoping that this is a simple oversight on my part, but any help or information would be appreciated!

EDIT: was able to update to android firmware v22 using by following https://www.oesf.org/forum/index.php?topic=36336.0 which seemed to resolve the issue with the options not appearing, however the codi has stopped working since doing this with the firmware not being recognised and unable to update automatically or manually.

Hey,
I went for the GPD Pocket 3, but your needs may not be the same as mine.

Gemini PDA - General Discussion / Gemini PDA replacement

« Last post by covex on October 17, 2025, 03:18:14 am »

Here we are again in 2025 - hoping for better to come when Gemini was released but the Planet Computers seem to go havoc. My Gemini battery is sometimes suddenly dying and its Android is getting too old. So where are you (community) going now? I do not have a time any more to fiddle with devices, need something that works "out of the box". Any suggestions on what could replace the Gemini PDA?

Yeah, and directly filming the LCD was too difficult with a cam because the LCD reflects too much light and it acts as a mirror.

Code: [Select]

PDA ---- serial ---- laptop ---- VGA ---- VGAvideo-grabber


I didn't know this was possible. Too bad it won't be possible to do the same with a video output e.g. showing the Sharp ROM desktop GUI, not enough bandwidth on the serial port for a start...

I believe your bootloader is shown at

v3-rev, is shown at 13:16

Aha, missed it, it shows a bit more of this. Is that clip showing it running on an emulator?

Varti

It shows a serial connection to a C1000 running my bootloader as common application on GNU/Linux (Gentoo 2009, kernel 2.6.24).

The serial connection (115200bps 8data 1start 1stop no flow) was recorded on a GNU/Linux laptop running GNU/screen.

Screen works better than minicom in this case because it offers full terminal support!
