Cosmo Communicator - Linux / Installed TWRP & Debian/KDE Plasma - Some Issues

« on: February 27, 2020, 11:13:01 am »

OK, I've figured it out:

You need adb on your PC, with that comes fastboot tool, what you need to do is run

`sudo ./fastboot reboot`

If you are stuck in the fastboot option, I have found that if you hold FN/ESC for several seconds the Cosmo will switch off.  You can then switch on normally to get the boot menu.

Cosmo Communicator - Android / Boot error after setting up rooted android

« on: February 26, 2020, 12:04:34 pm »

I have now unlocked the bootloader using fastboot following instructions in this post   which advises https://www.thecustomdroid.com/unlock-bootl...fastboot-guide/.

The Cosmo now boots into normal android and the SIM works!  I will have to reconfigure everything again as the unlocking wipes all the data, but there was no data on it anyway.

Cosmo Communicator - Android / Boot error after setting up rooted android

« on: February 26, 2020, 10:30:43 am »

Thanks SwordfishII for a very clear explanation.  After posting I looked around the forum again and came to the conclusion that the non-rooted android image was shared with the rooted version (but only after I ran into problems of course).

It seemed to be the installation of Magisk which prompted the verification failure, but this step is called up by the Planet Linux installation guide.  Have I missed something here?

Do I need to unlock the bootloader to get past the verification check?  If verification has failed does this mean that future OTA updates will fail?  There is nothing in the Planet installation guide for Linux about this.

Alternatively, I could try to flash the original android V19 using images from the forum, but I have no experience of this process.  AFAIK Planet do not provide a method of reverting the Cosmo to V19.

I can run the rooted android, but it fails to recognise the SIM and so I have no phone or 3G/4G data, and normal android fails to boot.  The SIM is PAYG and has no PIN, and it works in another phone.  I really need mobile phone and data services on the Cosmo before I can use it.

Help and advice needed on what to do next.

Cosmo Communicator - Android / Boot error after setting up rooted android

I have followed the instructions from the Planet support website to re-partition the Cosmo and install rooted android and Linux.  However, some of the boot options don't work. Is this to be expected?  Have I missed something?

Initally NORMAL boot started up android, but after installing Magisk it now says:

Code: [Select]

Your device has failed verification and may not work properly
Please download boot image with correct signature or disable verified boot
Your device will reboot in 5 secondsI installed Magisk using the instructions on https://magiskmanager.com/

TWRP boot starts TWRP with it asking for a decryption key

ROOTED_ANDROID boot works and Magisk shows it has been rooted.

DEBIAN_KDE boot also works.

FASTBOOT boot hangs

Is normal boot intended to provide an option for a non-rooted android?  I haven't been involved with the Linux beta programme that has been running recently.

PC Pro in the UK has a 3-page review of the Cosmo as its Product of the Month in the Jan 2020 issue 303, about two issues back from the latest issue.

Cosmo Communicator - General Discussion / Belt cases for cosmo?

« on: January 17, 2020, 04:14:07 pm »

I ordered a vertical belt case in brown and it is very good.  The case is made out of thick good quality leather with a secure belt loop.  This is much better than some other designs which have a hook that can come off the belt much too easily.  Mine came with antlers but would have been better without.  There is a loop for a hand strap but I have never used it so far.

Delivery is somewhat slow and attracts a customs bill (£4 plus £8 handling charge) in the UK.  I was confused by an email from Aliexpress telling me that the case was delivered and signed for when I had seen nothing.  I queried the non-delivery but I couldn't get a coherent reply.  A couple of days later a card popped through the door telling me that I had to pay the customs charge before I could take delivery.  I then went straight over to the local Royal Mail depot, paid the charge and collected the case.  It would have been much simpler if Aliexpress had told me that it was in Customs.

Overall though a good quality case that makes it easy to carry the Cosmo around.
