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

[lagakappa96]

that's the possible culprit, cause if you only overwrite newer files, it can bootloop.

Are there more folks with volume button troubles? Cause when i turn the volume up and down, sometimes it will spontanyously skip volume steps. So you suddenly hear the volume much louder, louder then the volume button rotates. It must be some variable resister thing, with the temperature.

Yes, I used flash+download.
Even tried flashing other bootloader, "format everything but bootloader" and then download without bootloader. With two points connected and disconnected. Everything gives same effect with splash screen etc.

@lagakappa96 I bet everything is because of the preloader. Try the preloader from the rom i gave link or from xy site where username is xyauto and password is 123456. You need to flash using format+download, he must be checked in flashtool. https://easyupload.io/ws80sq

I have a lot of roms at this moment, not everyone of them works. What i do is to copy the all files of rom who works, and after that i copy and overwrite the files of rom who not worked before over the rom who works. Few minutes later i have rom who works. Everytime i work with the same preloader i know it works without problem. If the preloader is f*cked it will show you black blank screen. You can try it when you find rom who works on your device.

Hi, I have this unit, and have an issue to resolve, everytime I start my car it goes to logo animation that is taking more or less 30-40 seconds.. and the date and time just continue from when i shut down the car... Hope you can help .. Thank you.

i would update your firmware, copy files from this link to a fat32 formatted usb stick and insert it in your radio.

Hello after updating, I no longer have the steering wheel controls, do you know how? (besides the can bus is apparently not detecting but I can change the ventilation and the other things)
Thanks

you can reprogram those through factory settings (code 8888).

Does anyone know how to show the rear parking sensors? I can hear them - just not see them on the overlay of the reverse camera. They should be shown on the image of the car. Ideas?

I solved the gps issue. I saw video about gps amplificator and i saw how they put gps antena on the table, after this they put on it andoid device. I followed that logic and did aproximate the same. I glued the antena near the device with 5cm distance between them. Now all works. I think there will be good solution for bad gps signal if we use gps antena amplificator. I've ordered one and will wait to come soon. Cheers.

I tried multiple preloaders - included with roms, downloaded from xygala and from 4pda. Some of them give only black screen, some of them give the splash and black screen effect

Keep on trying, maybe in the other usb cable, it should work.

@quixcraiova do you think the yellow marked checkpoints are the ones for spflashtool?

I've tried to bridge these two points but it doesn't work for me

Look at these pictures, maybe you can compare with your own radio? I thought the theory was, that if you shortcircuit those two spots, then connect the usb cable while holding, spflashtool thinks that the internal memory is empty and can flash it again.

Another day - another firmware update and new launcher

Login: xyauto
Password: 123456
(they have firmware for other models too - use google translate to change chinese to english)

copied gongban_YT9216BJ_ui-hw-ota-v6.8.zip to usb and extracted to usb.
inserted usb and <Android upgrade> button becomes available on the below screen.

After update - if PlayStore or apps freeze, reset Android settings and system settings fixed things for me.

Hope that helps some people....

Hello thanks for @mark-1978 for the help
Did you Know if we can change thé color of the touch Button at the left ?

Well I flashed everything, got the green check mark and now the unit seems completely dead. Screen will no boot at all, even with no other cables attached.

 

[quixcraiova]

@Moynia, disassembly the device and try flashing it with test points. You can see picture on mark's post here in this page.

@lagakappa96, dont give up. Im giving you the original factory rom from my device recieved after i spoke with seller. Format USB to fat32, decompres archive , copy to USB memory and insert it to the headunit.

Will definitely give that a go. I have a bench power supply I can hook it up to at my workbench at the autoshop I work for.

For reference, here is my device info (before I broke it LOL):
Device: YT9216BJ_00012_V0001

And here is my SP Flashtools:

2 things to note. I was getting an error for the flash so I did a Format Whole Flash except Bootloader (probably mistake 1). I also changed the scatter to one for the MT8127 (should I use the one provided in the ZIP file here in this thread aka. "stock" scatter?).

I still have USB access so not all hope is lost. I am just an idiot who did not back up his stock firmware . My experience with Mediatek processors is limited to a few BLU phones I developed software for back in the day.

 

[quixcraiova]

Keep calm. Even i did not made backup. From there began my journey in this forum . Everytime i use format + download with checked preloader, but not alltime preloader works. Try to download firmware for 9216bj from xy site and the factory preloader from there.
