Firmware
Attention, all actions you do at your own peril and risk. If everything works well, everything turns on, turns off, does not puff, does not buggy - then you do not need to flash anything! This is especially true for the MCU, if something broke during the MCU firmware, roll back to the previous version and do not touch it anymore, the MCU flash drive has a very delicate memory, and there were cases when you received the MCU after the firmwarekripich, so think ten times before stitching an MCU. There are no ways to restore a brick with a damaged MCU firmware today, just replacing the motherboard.

If your firmware is older than December firmware, then updates in the form of ZIP will not be accepted by the system. You must first upgrade to December using a special bootable micro SD card,and then later on more recent firmware via ZIP archives.The boot is only one of the two uSD slots.
    The same December firmware from a bootable uSD card will help restore the Android (but not the MCU) after almost any problems with it and from any distorted state. , if it broke, or do something for themselves and did not work. Flash it, then upgrade to the correct version;

Attention! Those who had the android 6 out of the box, it is strongly not recommended to make the transition to 7 androyd, after the MCU firmware From 7 adroyd, there will be no way back, you will treat with the MCU firmware from 7k forever, if you return to 6, then flash the MCU to version 6 will not work. On Android 7, old motherboards may behave unpredictably, in most cases the built-in microphone stops working and the volume of the bluetooth will be reset on reboot.

  1. December firstsew through phoenix, then update Os_update, it has 2 MCU for both radios, a separate linkMCU for both radios from November 17!
  2. December second (7) for GU UNI707-2GT3,23.12.2017. In the same place MCU from 12/06/2017 (for radio 7786), put in the usual way after the Android firmware. Firmwareonly via PhoenixTool for example going in set with firmware or this With a bootable microSD card, because updated flash drive image completely. Only one of the two slots microSD GU boot. See details in firmware instructions The fact that the December firmware from 2016 is true for this one. After firmware make factory reset in Settings-backup \ reset. Firmware deodexed . If the firmware freezes by 50%, you may need to download and write it again , to another flash drive, through another card reader, etc. Do not forget to remove the microSD card after the firmware, otherwise the GU will start flashing again. It is impossible to update the GU on Android 7 with a USB flash drive, if you do not have microSD slots - look for where to solder them, or try firmware from a computer via USB.

Attention! When upgrading from old firmware (until April?)all the settings of the engineering menu flies. Go there and record / take a picture of them before updating.

Attention! If you have a radio module onTEF6686, you can see it on the line of the MCU version, do not flash the MCU from regular firmware -will stopthe radio will work, and the music will hiccup, even if you select TEF6686 in the engineering menu. In fact, since March 25, 2017, the MCU firmware supports only one type of radio module. Only a special MCU for TEF6686 is suitable for you.from hereor mirror - MCU20170505and20170601, or TEF6686 of p.17 firmware.

Attention! If you have GU1DIN with retractable display, do not flash it with firmware from here - displaystop working. You can fix the firmware with a special display driver in uboot. Here is the versionMCU dated 08/15/2017and uboot only for such devices. There is also a file with a list of changes in the MCU. Butother MCUfor 1DIN devices withdetachable front panel. Think twice before updating 1DIN devices.

Attention! To upgrade from old firmware versions until December 2016, as well as to upgrade to Android 7 (or roll back from it to 6), a special procedure is needed - with the help of the Phoenix Tool utility (complete with the December firmware, the same video) you need to create On a computer, a bootable microSD card with firmware from an .img image, plug it into the GU slot (only works in one of the two slots, if you have one of the slots unavailable - you can swap them in the engineering menu. inside, behind the display) and turn on the power. The firmware process will begin automatically, you do not need to press anything, instead of downloading Android, there will be a yellow-green progress bar immediately after turning it on. You don’t need to interfere with the process, it’s about 5 minutes. When the progress bar reaches the end, wait a couple more minutes, then be sure to remove the uSD card. Carefully, she can jump out and get lost. Turn off the GU and turn it on again - the download will go. Do not forget that the hidden partition with the boot will remain on the card until deleted, just formatting it in Windows will not remove it, and if you turn on the GU with this uSD card without cleaning it will start flashing again. You can delete a partition by formatting it in PhoenixTool or in a camera, recorder, etc. device. If the firmware is not running - try to download and write it again, another microSD card, etc.

Mirror firmware here , making copies is welcome. Mirror copy on 10/14/2017 from * edi_08.
What is an MCU and why should it be stitched separately?
The MCU is a specialized microprocessor that controls the entire PG, turns it on and off, adjusts the volume and equalizer (giving commands to the audio processor), radio (tuning to frequency, RDS), Bluetooth, switching audio and video signals, handles button clicks on the steering wheel and signals from Canbus where there is, etc. If you exaggerate a lot, you can say that this is one of the main devices in the PG, and the block on Android is only a beautiful interface to it. More details likehere. And the MCU file is its firmware (in encrypted form, decrypted during the firmware process). Firmware of something "wrong" in the MCU is a good chance to mimic the radio tape recorder, to lose control or functionality, but something "wrong" - to correct the existing glitches in the above (together with the correct configuration). The resource of MCU flash memory (pdf 1000 rewriting cycles, but there are nuances) is less than the board on Android, so you should not reflash it too often.Heremore details. If there was an MCU firmware error - do not turn off the GU, try to sew up the version that you had before, and hope that it will work. There are no ways to restore the state after an unsuccessful MCU firmware, except for a complete replacement of the motherboard, and, alas, there were already three cases of bricks (in one of them the seller, Marubox,replacedThe motherboard, after which the GU worked). But in most cases, everything goes fine.

I put myself on Skoda such a device (Allwinner 1.6 GHz T3 Cortex, 2GB RAM, SMARTECH).
Navitel earned only license, when you start the Yandex navigator, the sound from the radio and player disappears (occasionally adding volume to the settings helps). Updated ES Explorer with other applications, lost files from the backup folder. I had to restore the firmware from the one that the seller sent (os_update_20170210).

Hey. It depends on where you want to install the logo))
If as a screen picture, you go into the settings - the screen - the wallpaper and choose the desired logo.
If as a picture of loading the screen, then in the usual way I did not succeed ... I went another way ...
Through ES File Explorer opened the LOGO folder, chose the desired logo, opened it, clicked three dots in the upper right corner, chose to install in the opened tab as a screen load image

It is necessary to tap alternately. "Kernel version" - "OS version" - "Kernel version" - "OS version" - "Kernel version" - "OS version"

Dimka-77rus @ 03/14/17, 15:56*
When you turn on the Yandex navigator, the sound of the radio disappears, what could be the problem?


I have onthisThe model loses sound when you turn on any application that is assigned to the "Navigator" button in Settings - Settings FAKARD - Basic.
If instead of Yandex-navigator to assign some other application to this button, the sound from Yandex will stop disappearing, but it will be inconvenient to use.

However, in the FAQ in the next post it is written about the secret menu, if we have one, it may help to twist something there:
Settings, about device, tap kernel, tap os version, tap kernel, tap os version, tap kernel, tap os version. 3 Times each. Secret menu appear.


What does not like:
1) No sleep mode at all. Full load every time you turn it on.
2) Root does not work at all - when you start KingoRoot, the radio is restarted by 90%.
3) Cpu-Z shows the temperature of the processor 80-90 C - if not lying, somehow it is too much. CPU load at the level of 10%. I will disassemble and put the fan in a regular place and, possibly, a radiator.If anyone is not lazy, please see what your CPU temperature is.

What has already happened:
Due to improper power failure during installation (the navigator updated the cards at that time, it seems) a file system error occurred on the built-in storage - the SD card emulator. As a result, it was mounted as read-only and nobody could write anything there, and navigators gave out strange errors, besides, the ability to use almost 30 GB of memory was lost, which is just a shame. The treatment procedure involves either formatting (better on the computer), or getting root andtreatmentvia fsck_msdos, but neither did. However, when trying to get root through KingoRoot, the radio tape recorder restarted, and corrected errors itself. Lucky.

Perhaps someone will be useful:
Protectiveglass7 "size 153x85 mm - I don’t know yet whether it will work or not, I will write as an example.

Concerns many models of the radio tape recorder - if when you connect your phone via Bluetooth, the sound from it (youtube, navigator, player, etc.) is output to “nowhere”, you need to either launch the Bluetooth application (phone) on the radio tape recorder so that it will still go from phone via BT sound, or in the phone, go to the bluetooth pairing settings and disable the audio profile (A2DP) for the radio there. At the same time, the phone will not attempt to transmit via BT any sound made in this profile while the connection is established (and the radio tape recorder is not listening to the phone).

EML who managed to steal?
BT generally behaves in a strange way.
Sometimes the phone connects itself to the radio, sometimes not.
Inogoda you just need to click on the radio - pairing, sometimes you need to connect the phone with a new one and enter the code on the phone.
The code itself - I put 0000, it is reset to 1234.
In short, a glitch on a glitch with BT.
EML sees it in general, but it cannot, what code did not put the code on the radio tape recorder.
In short, why I did not buy HZ on R16 - I fell for 2GB of RAM ...
