TWRP Manual Recovery

This page is aimed at users that soft bricked their Cosmo Communicator by corrupting the the boot or recovery partition, for example because of improper use of TWRP.

First of all, if you can still boot into the original Recovery mode, then restoring a full Android firmware is easy. You will need to prepare an SD card following these instructions (Cosmo Android Firmware Manual Installation) and then use the Recovery mode to install the Android firmware.

In case you can't boot into Recovery mode, there could still be a chance of recovering the Android installation if you can boot into TWRP. The procedure here is a bit more complicated:

• As in the previous case, you will need to prepare an SD card following these instructions (Cosmo Android Firmware Manual Installation)
• In this case, please make sure you use version v23.
• After that, download this file and place it into the SD card under the cosmo-customos-installer folder
• Put the SD card into your Cosmo Communicator and boot into TWRP. Your SD content should be available in folder /auto0-1.
• Tap on "Advanced" and then "Terminal" to open the terminal application
• Finally, type the following commands (using the on-screen keyboard):

cd /auto0-1/cosmo-customos-installer

sh Cosmo_Installer_V23_TWRP.sh

This should restore your Andriod firmware on your Cosmo Communicator.

If you can't boot into either Recovery mode or TWRP then you will most likely have to send the device to us for repair.
