Hey there, i've installed the rom and my touch keys didnt work . I saw hot to fix them and all was ok untill i changed the rom with another rom . After this i bricked the device and was necessary to open it and to make concact between two dots on mainboard. I flashed with another rom and device started . After flashing headunit turns on and when desktop appears after starting my display touch dont work anymore . I wanted to flash again but i cant restart the unit . If i press headunit restart button this not restarts the unit for flash . Flashing now only works with usb cable and with connected wire on two dots on mainboard . Can somebody help me solving this ? Thanks !

Hi, maybe some of you can help me in any way - I have YT9216B 2G/32G

During flashing, I got DL_RAM Error, Iwhich was due to faulty cable.

I got another cable, it works, I can flash the device just fine. However, none of the firmware I tried works. I don't have a backup. I tried multiple firmwares - unofficial from this forum and official from xyauto file server.

Most of the time, it goes straight to black screen(no backlight) after flashing and turning on.

Couple of firmwares show Android (or DSP) splash, and after 2-4sec it blinks once and stays black (with backlight).

I tried to get the firmware from seller, he constantly sended me the same firmware, which did even load in sp flash tool (invalid scatter)

Any ideas what can I do?
[Android Head-Units] quixcraiova:
@lagakappa96 i have the same unit yt9216b 2/32 and at this moment im looking for the same. Unfortunately im now with firmware for 9250 and my touch screen and sensor keys dont work. Only with plugged mouse i can use the device. Tomorrow i will try with one of these and with the original preloader file from site : http://file.xygala.com/?dir=uploads/XY公版/9216/9216B/Android9.1/中文/横屏/1024x600/UI1_v6.5

I also am facing this issue. But I sent it back to the seller and he is able to use it in his car as well as on Artificial table setup. I have no idea what's wrong in my car that I see a black screen. It turned on initially and I was able to use it for an hour. But after that It went into black screen and never came back.

So I sent it back to seller and he is using it for a couple of days now. He sends me videos using it and says its working fine there.
[Android Head-Units] quixcraiova:
I tryed to install roms from xy site and as i expected scatter file gave me error... Someone with advice for this issue?
[Android Head-Units] lagakappa96:
Thanks for your response! I am a little relieved that i'm not the only one with such problem.

I have (I think) all of the firmwares for any 1024x600 devices. Even tried to flash couple of the with different resolution - it didn't work at all (as expected)

However - I can't open the scatter file from the fw you gave me.I'm using SP Flash Tool 5.1924. I also tried to open it in versions 3.1328 and 1344, aswell as in ATC Flash Tool 2017.07.14

Did you use other scatter file and map files manually, or did you use other method?

EDIT: I flashed it successfully, don't know why flash tool won't opened file, after restarting pc it flashed. But it's still the same thing - splash and then blackscreen.

Hello everyone,

I tried to unlock the bootloader with fastboot commands, but the confirmation system allows me to press the volume key +.

Unfortunately my HU does not have the volume buttons but only the wheel.

Attached is the photo of the motherboard, the highlighted points refer to the unlocking of the system in case of total lockout.

Can anyone tell me which is the volume + point to put mass?

Thank you
[Android Head-Units] rosrus57:
For anyone interested in the "Engineering test debugging" password after logging in, through the four eights...

It's no longer a secret - here she is:

26959910

From the menu there you could change the option for the stereo the system so that when the car is turned off, it not only stays stopped, but also turns off completely.
[Android Head-Units] rosrus57:
Sir Proff55 - These are exactly the points you mentioned ...

And here's how I took them out on the back cover ...

One (upper) volume increases and the other button decreases it ...

And do not give any of the conclusions "on the table" - both, as well as the others are not given to the table, but to the second with a larger diameter - in my case I soldered the white cable to this common point, namely the second point with the larger diameter ...
[Android Head-Units] Proff55:
Thank you,

so if I understand,

white / yellow = volume -

white / green = volume +
[Android Head-Units] Proff55:
Hello everyone,

I have a problem with TWRP vers. 3.0.2.0, which appears to be the only one to work on these radios.

I can't even backup the system partition.

After less than a minute, the video freezes and the system restarts.

Backing up small partitions like boot - lk - recovery etc. It does it without problems.

Screen timeout is disabled.

Did the same thing happen to anyone?

Is there a remedy?

Thank you all for the work you are doing.
[Android Head-Units] rosrus57:
No, it's the other way around - white and green are for reducing the volume, and white and yellow are for amplifying the sound. In fact, the connection between the two big points is to amplify the sound. Only it is needed to recover a broken device.

In fact, the wires are very thin, but enlarged in the picture they look thick...

The cables are relatively easy to solder at large points, but you have to be very careful about the small point - you have to have good eyesight and a soldering iron with a very sharp tip.
[Android Head-Units] Proff55:
Thank you,

I had already found the post where it was described the unlocking of the bootloader with the photo you attached.

[Tutorial] AC8227L head units - how to unlock the bootloader

I had already tried but with negative result, the system wrote unlock failed.

In the post was also put this: In the image I attached, you're looking for the points marked 1 and 2. The caption on the image suggests they connect to Volume Up, but on every unit I've seen these points connect to Volume Down. Your mileage may vary. The layout of these points can vary from model to model, but they're always in this area.

Points 1 and 2 I used them for a hard reset after a total lockdown. (Big brick), fortunately fixed by restarting Flash Tool.

However, it does not matter, now I have no intention of taking the radio apart and trying.

Even with the bootloader locked, I rooted, installed TWRP, updated ROM, installed FMRadio with RDS, fixed the Mac Address that changed with each reboot etc.

Before doing anything, I had done a complete system dump including the userdata partition.

Thanks again for your concern.

I have the same HU as yours with 2/32 memory and also want to update, but could not download TWRP for the 2/32 HU. Is there any possibility getting a copy of yours?

Thanks
[Android Head-Units] motinka:
I flashed the radio, picked it up well, as you can see it in the picture. Then I assembled it, and after turning it on, it's the same as it used to be.

Black screen, side touch buttons illuminate.

What could be the problem?View attachment 5230795
[Android Head-Units] Proff55:
It could be the Preloader If you have the original dump try a flash of the Preloader only. Mine has no buttons but only the volume wheel, I don't know if it's compatible. Anyway this is mine without the userdata partition. https://mega.nz/#!XHhRDQaT!u5YAjmBN0BHIQNj1iOO_n3gQAXN8FonK5apXo4rToPE

If you think you need it, then you have to activate the keys. Good luck

Hello,

Unfortunately after Flashing a wrong firmware I made a Hard Brick.

Now connecting the USB cable is not detected by the PC.

I tried with the Test Point with current connected and also without, unfortunately

the PC does not recognize anything.

I also tried with the GND cable to do the Test Point but nothing ...

I have tried in every way, but nothing does not give signs of life the usb ....

Can anyone help me?

My model is originally a 1/16 YT9216B.

Thank you.

I use the USB cable out from radio, i ever use it to flash...
[Android Head-Units] quixcraiova:
This is another device as i see and its different from ours, can you make us photo to main board in the upper and bottom side?
[Android Head-Units] Proff55:
A Hard Brick happened to me too.

I solved with the Test Points, but be careful, I used a piece of electric cable, because with the tip of a screwdriver it didn't work.

Radio off and disconnected from the power supply, I start Flash Tool, I short the test points and I connect the USB cable. When the red line appears in the Flash Tool application, I can remove the contact on the Test Points.

Attention, after a Hard Brick, you must flash your ROM including the Preloader. (Full ROM)

Good luck.

It installed nicely once I connected the flash drive in USB2. but it gave error in USB1. Also remember to format usb using sdcard formatter (FAT32). Note: the version 20190624 is Not HiFi.
[Android Head-Units] cafsta:
Yep flash drive was formatted using SDCard Formatter. I used USB2 as with my previous update.

What difference does the HiFi not being there make?
[Android Head-Units] EagleSoldier:
Did you installed it via System Update, or via boot update ?

Best regards
[Android Head-Units] fani:
System update.
[Android Head-Units] fani:
No Difference.

I have not noticed any difference in performance or otherwise by updating to 24.06 firmware from 22.05.

The same is the case with MCU 2.8 and 3.1

They seem exactly the same.
[Android Head-Units] ramnkc:
Any idea how to update it via twrp?
[Android Head-Units] EagleSoldier:
You can boot in recovery mode via android terminal emulator: reboot recovery

And after that you can mount USB storage.

But you cant go back to main page of TWRP.

You have to unmount usb again to go back.

That means, Im not sure you can flash the rom via TWRP
[Android Head-Units] shiner88:
I think it does.

If you press go to home while listening to any radio station, in the notification bar, you will notice a new icon. The icon shows station name and info. Also if you download MTK engineering mode, under radio, you can see rds infos. Another clue is the autofrenquecy function (that works really bad, and i want to turn it off). So, I'm quite sure the problem is only the radio app.

Ideas anyone? :confused:

Sorry I am far from being a technical guy .... does it mean that one will heat more than the other ? Some additional explanation will be highly appreciated

Thanks
[Android Head-Units] edit4ever:
This shows the power draw as the units goes into deep sleep when you turn off the car. The nice thing is that it doesn't immediately shutoff. So if you stop for gas...turn off the car...but then move the key to the accessories position, the radio will just stay on.

If you turn off the car after 50 seconds it reaches deep sleep - and the 10.7 mA is very low and won't drain your battery under normal use. What's also great is that it wakes up from the deep sleep in just a couple of seconds. So best of all world's!!

Hi, Headunit-Users.

I have successful upgraded a 8227 L 2GB/32GB alps by sd-card. But now im stuck, I lost control over the device, because I didn’t reset it before, I think. A year before in my googleaccount, there was an option to setup a PIN. I did it and every time the unit restarts, I filled it in. The same procedure like in my smartphone, no big deal. So now I flashed it with a newer firmware-upgrade found at xda. Its booting normal with the pie-logo and shows the pin-entry. But now my pin, I haven’t forgotten, didn’t work no more. Steering Wheel Controls are functioning partially. I can get in adb-mode and boot recovery, then I’m lost, because Vol up and down didn’t work. The device is disconnected from my google-account since the upgrade. In the background I can see a task like account-action.

With adb I can erase apps. Are there some more tricks with adb, to get it work? In Recovery mode it stays on the entry reboot, but even an external keyboard wont work here, because no usb-drivers loading at this time. Is the only way to get it work open the device and recovery it with a pencil bridging two testspots??? By the way, the radio works and I can

change stations, I can hear music by Bluetooth-connection, I can set on and of wlan and connect to open networks, someone can call me and I can hear him, but understanding me is bad. Only the f… pin don’t let me use the device …

For now Ive learned, before upgrading do a factory reset!!! Was never before on my china phones a problem …

Maybe the geeks here can enlighten me, how to start again with my head unit.

Greetings

I have one of these units with Android 10.1 (in my case build is ZXDZ_2020[...]) and I can't seem to pair OBD-II dongles. I have BT 2.1 and BT 4.0 and neither works. I am going to resort to a wired ELM327 dongle but if anyone has any tips I'd like them. Unfortunately I haven't found anywhere on this unit where I can set a BT PIN. I tried clearing data for the Bluetooth app but that didn't do the trick. I have tried a whole bunch of different bluetooth apps including the force pair one that claims to take your pin. I can pair the dongles with my phone. Ultimately I don't expect much from a $90 HU but this is still irritating.
