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.

   Herselffirmware(inside the same video instructions). The link is no longer available,mirror. 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.

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 PhoenixToolfor example goingin setwith firmware orthisWith a bootable microSD card, because updated flash drive image completely. Only one of the two slots microSD GU boot. See details infirmware instructionsThe fact that the December firmware from 2016 is true for this one. After firmwaremake factory resetin Settings-backup \ reset. Firmwaredeodexed. If the firmware freezes by 50%, you may need to download andwrite 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. In older GU versions, the second uSD slot happens 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 copyon 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.

Became the happy owner of this device. Installing in the car and rummaging in the settings I came to the conclusion that Android is somehow heavily stripped down. Can anyone have a firmware for this miracle of Chinese technology?

Hello!
Can you merge the firmware from the radio through dd? Or ask the seller for firmware?

I can probably if you explain how to read the firmware.

Through the manufacturer most likely it does not work out. tape recorder was bought in the online store. (((

If you copy to a usb flash drive, then instead of extsd0 in the way you specify usb0

Through dd mergemmcblk0p12andmmcblk0p13. In mmcblk0p12 there are firmware files (uboot, boot, system, MCU) in the format 92e82e86-1e25-11e5-bffa-000c29ba27c0 and they can be safely stitched from a flash drive through the "System Update" or Key to the mass. In mmcblk0p13, there are a lot of MCUs in zip, and in ZIP there are small firmware for updating MCUs via "MCU updates".

Slip does not work, every time loading from scratch.
Rear view camera fonit (but it can be a cable - today I will recheck)
Krutilka right switches radio stations, and changes the frequency.
Well, so in general - not bad.
Not bad at all.
If anyone knows how to solve the above problems, I will be extremely grateful!

Please explain the order and process of the firmware, I'm just new to this.

update.zip and mcu update separately
update OS first пјЊ then MCU

If the radio is loaded:
We write the update.zip file to the USB flash drive - insert it into the device, in 5 seconds the radio tape recorder will determine what firmware is on the drive and pop up a request - update? - click ok
The update lasts 3-5 minutes, at this time it is impossible to deprive the power device, turn on the rear speed.

After that, if necessary, write the mcu file and do the same.

If the radio is not loaded at the moment I do not know the solution.

In general, if there is no experience and no need to flash - do not do it. And read the branch headerGU on Android 4.1firmware from there is not suitable for this device, but a lot of useful information on the process. Especially "Neither the curator of the topic, nor the administration of the sitesavagemessiahzine.comare not responsible for your actions and, perhaps, dead devices! "
