Those who had radio on Android 2.3, may remember my firmware for it.
Today I want to offer you a firmware for the MCTD platform with a Rockchip rk3188 processor, Android 5.1.1 and a screen resolution of 1024x600 or 800x480. It's made on the basis of the latest official version from HCT.
You can install this firmware on your radio, if in Settings > About device > Version info>
MCU version starts with MTCD. After can be any letters, two, three, four - it does not matter.
Build number starts with rk3188.
Version info example:
Also, to restore the radio, if something goes wrong, you should be able enter the recovery.
The main advantages and trends of development of this mod:
New features.
Correction of existing errors and imperfections of the stock.
Best responsiveness in comparison of the stock + the ability for the user to improve this indicator.
The customizability. All critical changes made on my taste, you can customize for yourself or do as it was in the stock.
Twice the internal memory without using FUSE.
All changes made directly in application code without the use of Xposed framework for best perfomance.
Stability.
The stock design.
When switching from any other firmware, user data deletion is necessary.
If you are upgrading from a previous version, no data deletion is required, but it is recommended. Especially if you used microG in the previous version.
How to install the firmware ?
Extract the dupdate.img file from the archive to the root of the USB stick or SD card. It must be formatted in FAT32.
Remember to remove all other USB sticks, SD cards, modems and other devices from the radio.
Insert the USB stick in the USB jack. It is advisable to use the jack in which it is defined as USB1 (see, for example, in the player).
If you installing the firmware over a previous version, go to recovery mode, select the fourth item (update the system/mcu image from usb) and wait for system startup.
Otherwise, if you had a different firmware, go to recovery mode and select the fifth item (update the system/mcu image from usb and clear all).
After a while the flashing process will fail and the radio will reboot again in recovery mode.
Then the flashing process should restart automatically. But it is not always the case.
Therefore, if the process is not restarted, you must again select the fifth item in the recovery menu.
Of course, you can install the firmware from the SD card, but using a USB stick is more reliable and faster.
Also you can install the firmware through the System updates in Settings.
If you have an older version of MCU, I advise you to update to the current version.
If you like my ROMs and you want to thank me, I ask you to make a donation. You can find required details on my website or just click here.

How to install TomTom and other apps in Play Market that are not visible on the radio ?
You have to change just one variable in build.prop: ro.product.device You can do it with your favorite text editor or with this app
You need to change the value of the variable from rk3188 to another. For example, mctd or even rk3189.
Reboot the radio. TomTom will be visible in the Play Market.
In order to have TomTom connected to his server and downloaded the maps, it is necessary to add another variable to the build.prop: ro.serialno=right half of your serial number (16 digits) and reboot the radio.
Altered serial number will be shown in Settings > CAR > About device > Status.
This method has a negative side. Applications that are already attached to your serial number (e.g. russian navigation software Navitel) will require reattach.
So, after installing and running TomTom is better to return all back.
I know its a big ask, but I could help as I have 2 units and I m certain other MTCB owners would help test if you constructed an image that would theoretically work, send it to us, we test and report back problems, even carry on development ourselves to sort minor problems, the ROM looks so good.
stefcio007, this is my custom ROM with lots of changes. It's suitable for any MTCD device with rk3188 processor and Android LP 5.1.1
iGO and Torque work on it without any problems.
Installed your ROM, working fast after switching to MicroG. Have to test it a while, Torque is working perfect now, no "Adapter not found" issue *THUMBSUP*
Just one thing, where i can find the OEM Folder, want to install the DAB+ App.
quintez, thank you for your feedback.
DAB+ Application is missing in this firmware, unfortunately. I'll add it in the next version.
Currently, you can download it here.
