ROM / Firmware/ Brick Recovery for 7" Android Head Unit AC8227l YT9217 YT9218 1/16GB

[bicer79]

yes, but you need Root access.

So how do I access root? Do you have a video about it?

Hi guys, I have this device:

Android: YT9217C_00005_V003_20190410_HIFI
System: Android 8.1
Kernel: 3.18.22
CPU: A7 1.3Ghz x4
Capacitance: 10000uF
CanPRO: Raise-09-12Fiesta-V4.1-Connect
DDR: 2Gb
Flash: 16Gb
Display: 1024x600 9" Inch
Amplifier: AC7315 MOS bile duct 45W x4
MCU1: HW8227L-3.3-SW0-1.9 (Then 3.1).

The steering wheel buttons do not work with the included Raise CAN decoder. However I noticed something:
If I go in Factory menu (8888 pin) and I click on "MCU info test" or "CANbus debug", I have no output when I click on Start. I tried to update the MCU firmware to version 3.1, still same issues. But from the system info I can see the CAN decoder being connected.
I have the feeling that my android firmware cannot talk to MCU and CAN, is there something I need to install to make it work?

Hello, I have the YT9213A / Android 9.1 / MCU 3.1, as you can see in the image http://prntscr.com/rzw9ll
My problem is that I can't control the balance or the equalizer. The icon doesen't appear on my device and when I move any slider from the equalizer, nothing really changes in terms of sound. I've heard that is a problem with the firmwire or something like that but I can't figure it out what should I do. Which are the steps in order to reinstall/reflash a compatible Rom for this model. If somone could help me I would really appreaciate it because right now this forum is my only hope. The sound is really ****ty and it doesen't worth to keep it at this state if I can't find any solution to fix it somehow. Here is a picture with the equalizer menu, where the audio settings icon is missing http://prntscr.com/rzwe9z
Also, when the rear (parking) camera activates, it doesen't make any sound to warn me about the obstacles distance.
Thank you and I'm waiting for any solution!

No one with this issue?

I've recovered a HU but when it boots up it goes into the android bootloader screen and moves up and the recovery - ADB and normal boot options. But as I have no touch screen yet I can't select any option. Anyone solved this problem?

I had a similar issue until I went into protocol settings and set it to the type of vehicle. Also, I read some steering wheel controls need extra wiring to the Key1 wires on the stereo. Sorry, not a lot of help but that was my experience

you need to push Vol- button to "ok" any option. there is a picture in 1st post.

I already went in that menu and select Raise - Ford - Fiesta 09_12, which was the factory default settings, and also doesn't work. Tried to select other CAN/Ford type, same issue. I am really curious, if you go in the factory setting, click on MCU debug -> Start, do you have any messages on the screen? I don't have any debug message for MCU and CAN. I suspect there is something wrong on my Android system, maybe a missing package or wrong MCU firmware.

Thanks mate touch screen not working but I managed to short the golden points to get the OK to work. Now just need to get the touch screen ribbon working properly.

MCU doesn't do anything when I press start, CANBUS runs a list of numbers as shown in the pic. Means nothing to me but might yo you.

Thank you so much!!! That help a lot

So apparently MCU doesn't output any info, even on a working device. But for CAN that means my android is definitely missing some CANbus APK or driver. I will look into that

I'm kind of a noob to this Android radio business but how exactly do you get the root firmware on the device I've tried to get into recovery witb the reset button and no luck ?

Hey guys no one seems to have answered the ques regarding Google assistant. The ROM I installed says that Google assistant isn't available for this device. Anyone solve this?

Information sharing re Video inputs

I just solved a problem I had where none of the video inputs would display an image. The problem was due to incorrect video format setting. To modify go into factory settings and select the second menu option, here you can change a ton of settings relating to reversing camera and radar. It's very comprehensive and full featured, well worth a look if you have a camera and canbus connected.

I tried to connect the Nokia AV cable to share smartphone to the device but I only got sound no video.
Probably worth a recheck. Which settings did you end up using regarding the AV inputs ?

You need usb male to male cable, attach it to usb1 on the device. but not yet connect to pc. Run the sp flash tool. and select the correct scatter file. Then run which ever function you need. after that connect the usb cable to pc while connecting these two test points (picture) with a small piece of wire to each other. After it is recognised and operation starts, you can release the jumper wire.
