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.

Hello. Is it possible in the settings of the radio to set that with a long press on the button the radio tape recorder was turned off completely, and did not go into sleep mode?



Rep: (0)
Hi guys!

A misfortune happened, I bought it on a well-known site.http: // not validlink / kAm, everything came, everything worked fine and everything was fine, but the seller threw me the android firmware from 7.1 to 8.0, and threw off the MCU firmware, I didn’t even know about what it was, they said I updated .... first everything was fine, departure for a week, everything worked ... but on Thursday, I went to work in the morning, went to listen to music all day and everything was fine, and by evening I sat down and started driving, I realized that something was not right .. The music did not play ... it rebooted the GU, and still nothing works. I'm trying to start the player on the radio, but neither does it react to the icon on the sensor or the button on the GU ... As a result, I have not opened any factory applications (radio, player, BT player, aux, dvd and others) , but the installed applications are launched (Es Explorer, Google, Play Market, Tungul and so on ... I had to go, did not bother to go ... In the evening, having decided to check what happened to him, I start the radio tape recorder, and immediately noticed that now neither any mechanical buttons on the PG are working, they just don’t react ... First I I reset the android, it did not help, then I found the MCU reset point, tried to do it, but nothing even happened .. Then going to the engineering menu I noticed that all the points there were reset or turned off, I tried to check such items as Disk. DVR, F.Camera and others, hoping that will help, but nothing happened.The next step, I noticed that the settings in the engineering menus are reset immediately, the settings are also reset in the android system but not all, but for example I could not adjust the date. Next, I decided to try to flash the MCU and Android on a new one. I put an android on another flash drive on another MCU (absolutely different flash drives), stick a flash drive with android into the GU and nothing happens ... The Upgrade window did not appear .. I insert another flash drive with MCU and also no result ... Then I contrived with all the ways I came up with: inserted flash drives after rebooting, reset, reset, flash drives formatted each time (not quickly), in general I killed an hour and a half, the result is zero! The next day, in the morning I got into the car and started to warm up, until I decided to warm up, let me stick around, at first it was strained that the sensor did not react in some places, I thought that I was cold ... then I noticed that the strip on the right and below on the sensor was not working ... flew calibration. On this day, I tried to find a recovery, tried everything, even with the keyboard, nothing helped, just tried to sew it with flash drives, also to no avail ... I tried to hook it to the laptop, the laptop didn’t react to it at all ... Today , I just wash my hands and do not know what to do with it .....
As I understand it, the radio on AllWinner t3 p3. At the moment, shows the version of the MCU: STM8, CAN module does not see at all? Here I recorded the video, sent the Chinese, he is still silent ...https://yadi.sk/i/_akbRPyMUzq-pA

Guys, I beg of your help ... what to do with it? ((

Hey. I can not flash on another firmware.
I insert a card with firmware. After the update from 0-100, it climbs 2 times here is a window with the process going from beginning to end and the radio is turned off. (The screen goes blank)
Then you can turn it on with the button. But the firmware remains the same, even the settings of the radio and TV.d. remain the same. True sentences all blows. What cant? Downloaded a couple of times this

My friend, I have exactly the same as yours!
Bl was sewn ... Tried all the options described on this forum, all the ideas ran out, nothing happens. The MCU crashed completely, poked reset 9 times - nothing, recovery does not work, although the keyboard and mouse work, etc. It remains to hope for the Chinese, perhaps this is a massive problem and they are already looking for ways to fix it. Those who wish can drop the update files, but now I think no one wants to update (upgrade to Android 8.0 and MCU, dated December 18). To the Chinese, wrote on Thursday, here is the answer: you can try again for the mcu software. On Friday, I still wrote to him, but he always answers once a weekday, early in the morning, I look forward to hearing from him tomorrow.

If I understand correctly, if they were confused, then with each reboot of the radio, the date, time and radio settings would be reset, but I do not reset, and the sleep mode sometimes still works, but rarely)) so I think the problem is soft. ..

Hello. Help is needed. Such situation. Put in kia rio our GU. With the standard acoustics, everything played well. Replaced the front with Kalon Ural, it became even better. Found for free 4 channel amplifier. He put the wires, connected two channels to the front, two channels with a bridge on the sub. I connected the amplifier to the GU, to the tulips Fr and FL. Rear kalonki and tweeters left to play directly with the GU. But when you turn up the volume, the rear cages and food begin to snarl very hard. And if you transfer the balance purely to the rear, everything is fine. That is, the locking of the calendars is performed while simultaneously playing the standard outputs and the amplifier. All head already broke. What do you think could be the case ???

Hello. Could you tell if anyone had such a problem as a non-working Asottu ZK28060 2gb + 32gb drive (bought from Irene Kia Rio for 2014) once only listened to the disc (not scratched), after pulled out and after a couple of months decided to listen again but the drive refused to accept the disc. Re-flashing the device did not help. It was in the summer, suspicions that the drive may be sticking from overheating? The radio tape recorder has not yet pulled out for inspection hands do not reach) decided to reflash thought will help but after reflashing in the settings where the information about the version of the android is displayed and the assembly, the system does not see the CD drive (accordingly, it probably does not receive power to it)

Greetings friends, I bought myself a CF-3017m (t8) and from the first days I started with it crap in the form of periodic reboots. Having written to the seller about this problem, he sent the firmware to the advised to reflash, and here's a question for you dear, I do everything according to the instructions, but the menu item does not open the firmware update (poking at it and not a fig). The seller advised me to change the flash drive that I did and without result , but now it has stopped communicating altogether. By the way, I bought Avtotok on the site, I do not recommend it to anyone.

You can, I have so configured. For a long press off, and somewhere else you need to put off and not sleep (unfortunately, I do not remember where)

ps. And, I found a screen - Panel learning - Power key function - Really shutdown.
