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 ...
