[Remix OS for PC] Enigma_tec:
Hi guys, at first sry for my bad English.

I have a big problem and i need help to solve this. One of my heater thermostat make problems. I started a firmeware update and make a big mistake. Now it is always in update mode. I found a solution for that problem with Remix OS.

Install a current (!) VirtualBox and VirtualBox Extension Pack for USB support DONE

Blacklist btusb module and possibly more specific device drivers like ath3k if it applies to your system to keep the Bluetooth USB device unoccupied (revert this later!); give chmod a+rw permission to the USB device file under /dev/bus/usb/xxx/yyy, see lsusb I skiped this step. I hope it was okay.

Install RemixOS in a VirtualBox VM, add a USB device filter to expose your Bluetooth chip to RemixOS DONE (Install Remix on Ubuntu 64bit Bluetooth is working fine and Remix OS show me the thermostat.)

Install calor BT on RemixOS, run it at least once DONE (app for the thermostat from the play store

Determine the device Bluetooth address: Open the device by unscrewing the four screws, then gently pulling the turning knob outwards, remove the cover; locate the "ADDRESS" QR code printed on the front of the circuit board; scan the QR code to retrieve the Bluetooth adress in form M001A22XXYYZZ (I had to take a picture, crop it and then run the QR scanner on the image); the Bluetooth address then is 00:1A:22:XX:YY:ZZ; replace the cover, again gently pulling the turning knob outwards, turn it to make it fit the turn encoder; screw the cover DONE MAC is M001A220EE2D5

Manually set up the calor BT configuration to address the bricked device. Save this as container.json, replacing all XX:YY:ZZ by the address determined above: {"clients":{},"devices":{"00:1A:22:XX:YY:ZZ":{"availableFirmwareVersion":null,"firmwareVersion":null,"groupId":"17f51411-4be0-4155-98f6-9a03bbde5681","groups":[],"id":"00:1A:22:XX:YY:ZZ","label":"Device","lastStatusUpdate":0,"lowBat":false,"unreach":false,"updateState":null,"operationLockActive":false,"temperatureOffset":0,"valvePosition":null,"type":"HEATING_THERMOSTAT"}},"groups":{"17f51411-4be0-4155-98f6-9a03bbde5681":{"channels":null,"devices":["00:1A:22:XX:YY:ZZ"],"homeId":null,"id":"17f51411-4be0-4155-98f6-9a03bbde5681","label":"Room","lastStatusUpdate":0,"lowBat":null,"metaGroupId":null,"unreach":null,"activeProfile":null,"actualTemperature":null,"boostDuration":0,"boostMode":false,"controlMode":"AUTOMATIC","maxTemperature":29.5,"minTemperature":5,"nextSwitchPoint":null,"profiles":null,"setPointTemperature":17,"windowOpen":null,"windowOpenTemperature":12,"type":"HEATING"}},"home":{"absenceEndTime":"","absenceType":"NOT_ABSENT","availableAPVersion":null,"clients":[],"connected":false,"currentAPVersion":null,"deviceUpdateStrategy":null,"ecoDuration":null,"ecoTemperature":0,"groups":["17f51411-4be0-4155-98f6-9a03bbde5681"],"id":null,"lastReadyForUpdateTimestamp":0,"location":null,"nonAbsenceGroups":[],"pinAssigned":false,"powerMeterCurrency":null,"powerMeterUnitPrice":0,"timeZoneId":"","updateState":"UP_TO_DATE","dutyCycle":null},"metaGroups":{},"weather":{"temperature":0,"weatherCondition":"UNKNOWN","weatherDayTime":"DAY"},"homeGroup":null,"inboxGroup":null} Maybe use http://www.jsoneditoronline.org/ to edit this. DONE change all the MAC address. I create the file container.json.

Now, install this configuration inside RemixOS: make sure the VM is shut down.

Mount the RemixOS VM image, first making the VM image available as a block device (using qemu-nbd from qemu-tools): modprobe nbd qemu-nbd -c /dev/nbd0 --partition 1 <path to RemixOS.vdi>

Now mount it: mount /dev/nbd0 /mnt

Copy container.json to /mnt/android-2016-06-30/data/data/de.eq3.ble.android/app_data/ (might vary depending on RemixOS version)

Unmount the RemixOS image: umount /mnt qemu-nbd -d /dev/nbd0

Boot up RemixOS; run calor BT; go to "Room", then "Device", then "Update firmware"

Firmware should be transferred (showing moving bars next to "UPD" on the device), then rebooted, device is then going to "InS" mode, turn it off and on again to enter date setup, etc.

up to step 7 I understood the steps so far. But now i'am lost and need help.

i hope somebody could help me to finish this solution.
