[ROM] [ROOT] [TWRP] [GUIDE] YT9216B Chinese Android Head Unit

then you must have flashed some wrong preloader. If you have a double din radio, you can disassemble it and shortcircuit the two spots to still flash a rom. If you have a single din radio, the radio is hold together with the wires against the outersides, so you can't disassemble the radio.

I do not have a double din radio.That means there is no way software or anything else

try taking the radio apart, i think it's all stuck together, so not only screws. But you can try. Saw someone who had only the pcb lying on a table, so it's good quality.

I do not speak English well. I think you said about the complexity of the wires.But I know I installed the wrong Android on the system and I know that the boot is gone.When it is turned off, it is a sign that it can not start the boot!

I know that Android is open-handed. And it can be fixed. But I do not know why it is no longer connected to the laptop system

ok, so you've got a 15 seconds boot. Then since the connection with spflashtool is within 5 seconds, you should still be able to flash it, or only another preloader.
So, you have a powerless radio, you should use the 6p usb connector(i think), so, put the usb cable in the radio, leave it disconnected from the laptop, then start spflashtool, load the scatter file, select 'format and flash' , then press the flash button, then connect the usb to the laptop.
It should start flashing right away.

I did it finally . My problem with touchscreen was with black cable . It was plugged not as required and because of that i had issue with touchscreen . Its not logicable thing because other two cables connects otherway. Im attaching pictures . So i`ve flashed my device YT9216B again with help of 4pda forum user sandr2010 , he told me to put otherway the black cable for touchscreen and after that i flashed with one russian rom token from 4pda forum and all its ok . My touchscreen works , my GPS works , my rear camera works. Only one thing i need to do , to connect external microphone , sandr2010 told me i need to unconnect from mainboard integrated mic (shown in white circle in the picture) and to connect the rc cable with 3.5 mm external mic and all will be ok . I give you guys link for the rom i use at this moment and all its ok .... I flashed with dissasembled device with wire method . Im attaching picture with what i have at this moment installed . The device works verry good without any lag.

Thanks for your help.I could not flash the device.I went to the repair shop and they said they should change the hard drive because it cannot be connected with a USB cable.

Just shortcircuit these two spots on the mainboard and connect the usb cable to flash a new rom.

you should stick the gps mouse to the front shield window.

 

[quixcraiova]

Same thing, satelites not in use. Is it possible to be because of the rom?

 

[mark-1978]

does someone know how to pair a bluetooth remote to the radio?

 

[quixcraiova]

What kind(type) of bluetooth remote?

 

[mark-1978]

What kind(type) of bluetooth remote?

Kebidu wireless remote for android. A small bluetooth remote for in the car. But although the unit finds the remote, it won't pair.

 

[quixcraiova]

If you want to pair them the kebidu password shoud be as your device bt password. Example for obd2 elm27 password is 1234, if i dont set my unit password to be 1234 it will never pair.

seems there's a pairing button on the backside.

*there isn't a button on the back, On the site it says that android go versions aren't compatible with remote through bluetooth.

Eh. I give up. Sadly, this rom isn't working for me. It's the same thing as before, splash screen and then black screen.
