I have a problem with the reverse switch, i already check the hardware and everything looks fine so i think is something related to the software.
Is there any update for this headunit? i attach some photos of the MCU and system version.
Thanks in advance.

Generic (XY Auto) Android Head Units Firmware Update
Hi, I checked if it there was a post about this but i didn't found anything, so, here we go. For those that have a generic or FY Auto firmware, here is a website where you can find the correct firmware for your head unit...

Hi...
Is device having a reverse wires ? (on wires harness cables)
And are they attached one to another (pink REV marked wires)?
If yes, problem is in software as you mentioned, mainly the cause is in the factory settings of device.
If board has AC8227L chipset then go to factory settings with pin code 8888 and go inside "OTHER" menu.
There must be option REVERSE or REV or BACK or something like that, if value is at 0 set it to 1 and restart device.
Then see if system recognizes reverse. If not recognized, return and set back old settings.
In other menues of factory settings are also solutions, try to find a setting for your reverse.

Yes it has a pink cable on the harness as a reverse switch, all well connected, in the factory settings (in this case the code is 000000) there's no reverse option or anything related

Take a picture of whole factory settings, including submenues in order to look for that setting. Or better, make a brief video.
Also, from that build number of yours you should check this
https://romprovider.com/stock-firmware-head-unit-zxdz-01/
for additional help guidance and firmware update. Inside are options to flash and install update- this is provided as is and I cannot help anymore if device is bricked, so read carefully and inform your self before flashing. If doing just firmware update its ok, no harm will be done just better software installed. Flash of unit is last resort!

The only doubt i have about that firmware is that my head unit is 10" that could affect at all?

It's an 8227l, the most common headunit, so yes, you can change the rom.
From that video : (take a picture of all settings before changing - for turning settings back if no effect)
-put setting EXTERNAL DEVICE to ON or 360VIEW or REARVIEW CAMERA (must be phisically present)
-PARK RADAR OPTION - change to other than default (if has reverse camera or something like that choose that one)
- for INTERNAL DSP option - if your device supports it activate this option also
- OPTIONAL (just see if will have any effect if you change that) - STANDBY OPTIONS - it must be "0 minutes" or "never standby" - it says to device to actively writing in internal memory
If any of this changed settings work please notify, if not revert to old settings.

I already try all the settings recommended but unfortunately any of them solve the reverse cam problem, im new in this, is there any ROM you recommend me to install?
If this not solve the problem it will not installing an update either.
First thing, remove the fuse from multimedia head unit and after 10 sec or so put it in again and power up headunit , then see if this removes any problems (various static electricity are causing also unit to underperform)- if not resolved try next step.
Next step is to HARD RESET a unit - when head unit is up in android system, press RESET button (ussualy in small hole). As soon it restarts start tapping with all five fingers on screen rapidly untill system goes in recovery mode (message will appear DETECTED - but keep tapping until you see recovery mode). In recovery mode system will erase all settings and tweeks that has been made since moment of unit first power up.
After unit boots up, when in system, install everything again. Prior to tweek up settings in factory menus/infotainment see if your problem is resolved, then turn off unit and restart (cold start with engine shut down).

Your device is having a different method of getting into recovery mode. We must find one specific for your device.
Do you have in factory settings "erase all data" or "turn to factory settings" option ?

I tryed to get to recovery using adb, but i only get a android image with a "no command" text, also tried to install TWRP and only get a blue screen, fastboot doesn't work, shell either. also i installed the rom you shared before, it work a little more fast and has a better launch, i contacted the seller and he promese he will send the original rom.
The settings menu has a reset to factory option but it didnt solve the reverse problem so i think nothing will or the problem is actually on the hardware.
If I would be in this trouble I would play with various settings of device in factory settings till found a culprit for problem. But first, I would take picture of all settings to make sure that if something changed wrong I can reverse again later to old settings.
It's just that, some setting is preventing that (I have in menu options "detect camera" and it is on "1" value) or some wire is damaged and not operative. Maybe it is a "streched" wire that is causing problems if wires are put together in a lot / harness cable. Faulty antennas (GPS, WIFI) or rearview cameras can make also problems.

Finally the seller send me the newest version and now it has a option on the settings to activate or dissable the reverse detection, if any one has the same unit, only need to copy the zip file on a usb and get in settings/about system/local update and mark the system option, then only press the start update button.

Okay, so i've been searching around on the internet everywhere for a solution that will solve this problem and the only place i could think of that would help was xda developers.
So, one night i soft reset my phone and much to my surprise, when i tried to send a text, it was stuck in landscape mode and wouldn't go portrait. Then the same thing happened when i used Opera...then when i tried to phone a mate, it automatically went into landscape and turned my speaker phone on (as i was in the middle of my town, he couldn't hear me amongst the crowd of people).
I have tried restoring factory settings, wiping my SD card and formatting the phone, but it didn't work. My local Carphone Warehouse said that it could be the software on the phone, but i am completely clueless when it comes to the technical side of things, so i have no idea how to update my ROM - if that's what the guy meant by updating the software!?
So please, any sort of help to solve this would make my entire year as i have come so close to forgetting about the phone and buying a new one.
Thank you.
read 'stuck in car kit mode'
faulty / dirty usb port possibly.
Thank you for suggesting that topic. I read through the various posts, they varied slightly from the solutions people used, though.
Sending my phone off for repair is out of the question now as many people posted in that topic that the repair people returned saying that they couldn't fix the issue as it was a result of liquid...or something along those lines anyway.
Some said to clean the USB port, I've done this lightly with a toothbrush, but no change. According to some posters, they said that some moisture/dust may have entered the USB port.
I'm getting slightly annoyed now as my pc cannot even detect my phone when I plug it in, so i cannot update the ROM or anything...strangely however, it detects it for charging via both my HD charger & USB connection to my pc? :/
i sent mine to o2 with the same fault,replaced the mainboard no problem. you should try the firm but gentle clean with a toothbrush, perhaps?and don't forget you can flash from sd card...
I had the same happen to mine after it got wet in my jacket, Had to send it off to HTC, Replaced main board etc,I tried everything beforehand to no avail.
Problem Solved
I have the same problem and solved it by BsB Tweaks 1.6

1. Run Bsb tweaks.
2. Menu -> rotation
3. Select (check) All programs
4. Options -> Rotation status -> disabled
5. Close -> Exit
6. Soft Reset
For Loud Speaker Problem:
1. Run Bsb tweaks.
2. Turn off Phone Slide Cover Option(From General Section)
3. Exit

Eonon has a new Android 6.0 unit posted:
http://www.eonon.com/Android-Car-GPS/2-Din-GPS-Navigation/GA2162.html
However it is only 1GB of RAM, so I'll skip it, looks good though
I got this unit installed yesterday. I like it and it seems very responsive. When I was digging through the menus to change the boot logo. I selected model change, "Toyota Camry" The unit loaded new settings and rebooted. Now my physical buttons don't work and there is a software eject button. I guess what I selected is to change the software to match different radio designs. Any ideas on how to undo this? I've selected just about every option on this list plus done a couple of hard resets.

No, Eonon sent 4 files for me to put on a microsd card and then select software update from the menu. I don't think it really reset anything because it still booted up with the Toyota logo I had selected earlier. So, it would show the Toyota logo, go off and then the logo reappears and then it went to the Maintenance menu. There was no way to move the cursor. If I reset the unit or powered it off by holding the volume knob in, it would just go back to that screen. I could also hold down the power button, then hit reset to go to a screen that says "applying update", but it always just ended up on the same maintenance screen.
Anyways...they provided postage for me to send it back. They should be receiving it today.

I wonder if a USB Keyboard would enable moving the cursor and making a selection...I didn't try it because I don't have one
So I got my new radio from Eonon. This one is working better. I'm able to use the screen mirroring whereas before I couldn't connect. The option to switch models in extra settings is now blank. I really like the resolution of the screen and the 16gb of built-in storage. The only issue I've had is Poweramp will sometimes quit playing music while I navigate with iGo. It seems to be overly aggressive in killing background apps.
has anyone who purchased and hooked up to steering wheel controls able to program the speech/mic button to run "ok google"? another thing...are you guys able to run netflix? i can hear and see normally, until i play a show, then i only have audio...the image doesnt show

Power off the radio, connect an USB keyboard and power back on; got to recovery and use the "arrows" of the keyboard to select the item that you want; once selected press "enter" on the keyboard

Just curious how you got to recovery mode. I'm in a boot loop on my GA2155 and can not figure out for the life of me how to get into recovery with only a reset button. I have a usb KB hooked up but I never get an OS to boot so I'm trying to get to recovery mode right from power up *somehow*

Hi all
I bought a second hand car stereo 8.1 reference 8227l Chinese without name ... see pics
I have several problems : impossible to find how to go into recovery and therefore impossible to root for now ... (I tested all possibilities: reset / power and all keys)
But more serious: impossible to have access to settings / accessibilities necessary for google maps which bug in navigation, or install a program like "velociraptor" to have the speed in real time
Cannot find out how to do a hard reset too : rolleyes: there is a reset / settings function but it does not do anything ... reboot everything stays in place
Thank you for help and good day
Usually reboot and volume +
Thanks for help but not possible with vol+. I'm not sure buttons are enabled during boot they're lightning only after android is running.
Android Head Unit 8227
Good day to everyone, ive also got a head unit 8227L from ebay, its a 7" android 8 head unit, none if the physical buttons do anything, they died after i changed the boot logo, i have tried putting it back to the original one but no help, on top of that, the touch screen dosent work in the cold, and here in the great white north, its 30 degrees below freezing for months, Ive tried everything to get them working again but no luck. I have to use a USB mouse to even do simple things like change volume, so needless to say, its a useless radio until i can get the buttons working again. Any help be greatly appreciated. Ebay just refunded me for the radio they quit trying to help, all they said was to just press the reset button, which dosent help

I do not have an 8227 unit but try to help here.
With my px3/5 and T8 units, I can remap physical buttons using either a built-in app, or Settings/Car Settings menu. You may try to find out available options on your unit.
There is a Russian forum for 8227 units and you may use google translation to see its contents: https://4pda.ru/forum/index.php?showtopic=930058 .
Thank you for your response, the touch screen works when the truck gets warm, and only when it gets warm, says on ebay listing that it only works to -10 C, and well it will be awhile for that to happen here, the real problem is the no buttons work, i went to that site you provided and google did a great job translating it, but unfourtnley didnt help my problem, also the picture provided looks different then mine, im not sure how to add photos so i cant even show you what mine looks like, but ebay item 273656041408 thats the one i have
I have an 8227 device but its a hizpo not the same as yours so I dont know if you have the same options. But on mine, when you go into the about device in settings there is a gear icon you can click on which the code 8888 works so you can access deeper settings. One of which is the buttons on the front.
yes, ive tried that option, i can key into the key learn option, but it wont program any of the keys, what i dont understand is, how would changing the boot logo affect any of the keys, it is the 8888 code as you said to get to the other menu page, there is however a slider bar at the bottom of the key study option, has Chinese writing before it, i can slide it from 0-55, not sure what it does or if thats my problem
defective gps module ?
Hi everyone.
I recently bought an 8227L chinese 8.1.0 android car head unit. Everything works well, except the GPS: it can't find any sattelites. The connection of antenna is properly made, I tried to put it in different locations, even outside of my car, but no sattelite found.
Is there any setting I can change (e.g. factory settings or so)? Maybe the GPS chip is defective ? How can I get into that ?
Thanks.
hi there and welcome here, possibly you plugged GPS ant into wrong spot, i know on mine the radio and gps ant look very similar, tho im not sure if thats even possible, it is normal for the radio to take up to 5-10 min for the first calibration. You may be correct on a defective gps antenna, if your antenna has a clear line of sight and its been on for 10-15 min, if its still not finding any satellites id go with a bad antenna, but im sure theres many more people here with much more experience then myself, hopefully someone else has better suggestions

Lucky to get a full refund. lol. Go to Car Settings, Factory Settings, enter password 8888, go to Physical button study and have fun. Remember that some buttons have multiple features like the power button is power and mute.
Btw, it is very hard to find info on these units. Weird since they are awesome for the price.

Oh yes you are absolutely right, in settings/ others/ enable USB2 debug and save/reboot at boot I can see a line at the top (don't remember exactly ... "waiting usb" or something like that.
Now I'm really afraid to try root as I don't have any backup and it's a second hand radio :silly:
Did you try rooting
Hello yes but flashtool.exe is not working on my laptop (I tried with Windows 7 pro)
Ok I gave a new try to Mekede root... so flashtool.exe must be at c:\ on the computer to work but when I put AC8227_android_scatter nothing happened, all is grey, 0kb/s. I tried to connect USB on unit but impossible to recognise (I tried to enable debug USB in dev settings) drive me crazy...
Edit : I totally bricked by flashing MekedeRoot via sd card. I opened unit and saw it's MEDIATEK MT6323LGA 1831AGAH CTG39W03
I'm searching drivers for Windows to connect USB but no chance for now
It looks like I may have come to the right place.I have one of these units from Ebay. It reboots every time power (ACC) is applied and again when you start the engine. I went back to the Chinese vendor and they suggested I do a hard reset. Now the left hand side of the touch screen X0-X200 doesn't work. Nor does any of the soft buttons on the left hand side.
I've gone into the factory settings screen and found the touch related functions; Touch Settings, Touch Test, Physical Buttons Study and debug touch.
The Factory Setting App looks similar to this guide on the Joying website dubdubdubdot joyingauto.com/blog/category/head-unit-problems-solved (I cant post links yet) particularly the Physical Buttons Study and step 3 where the X/Y deltas can be set. However, when I select 'config' in the unit I get a config file not found error.
So would it be possible for somebody to post a copy here of that file for me?
Also in the 8227L Factory settings Menu is the "export Config" option. That creates a file metazone.bin on the USB drive. Could I get a copy of that from a working system please? Mine is 1Mb but checking with GHEX it is pretty empty (0x00's). Also any clues on where it is located or how to import the data?
In /storage/emulated/0 is a file calibration.ini it has zero bytes does that have anything to do with it? A copy of that would be appreciated as well please?
Then there is the reboot problem. I have another, different, Android 7 unit in another vehicle it comes on and stays on immediately power is applied.
I have found this file auto_shutdown.sh in the root folder
I hope you can help please? I'm having trouble with the vendor etc to get any resolution or refund
Please help identify and brick the device.
I suspect this is some kind of KLYDE device.
The device freezes at the boot stage on the logo of the automaker.
Here is the link to aliexpress where I bought this device: /item/4000060317419.html
Does anyone wonder how to get into the recovery? There is only a reset button on the device, there are no more physical buttons on the device. Or how can I connect to the console?
On the motherboard there is a marking KD-ZXW-MB (V1.5)

You would get into the recovery, but that makes no sense, because the recovery is not usable without hard keys.
The only possibility is to use the firmware to get it back to life.
PX6_format.zip --> https://drive.google.com/file/d/1gXU13McO7XdTEMxOncy5pyW-5-OI1bF0/view
If you have the firmware of the unit, just put it on any formatted USB stick, switch off the unit, use the front USB for mounting the USB and reboot the unit.
All personal data and apps are gone in this case.

Thank you very much. I havn't firmware of this unit. PX6_format.zip - is this firmware? So i need to unzip it on FAT32 formatted flash? Right?
I wrote a request in support of klyde. I asked them if they produce this model? I asked about the firmware, model, instructions. And I received only the answer yes, this is our head unit. And nothing more.
So. There is no activity on USB. Somehow (rather accidentally when turned on), the Android logo appeared instead of the automaker’s logo (it was the same in the car once, while the rear view camera turned on when the rear speed was turned on). I inserted a flash drive and it appeared active. The process of updating the firmware has begun. Then there was an inscription (not photographed), saying that something went there successfully, remove the disk. I pulled out the disk, the head unit rebooted and again the same logo of the automaker and that’s it.

Yes, this unit is produced by Klyde and is sold with software adaptions by other reseller too. Slight differences in the menu but that seems all.
Did you use the update as written?
...as PX6_format.zip ?
After the first setup (graphic turning something) the unit goes in a shell based screen. Did that happen?
Have you pushed the micro switch for Reset afterwards?

I put the archive itself and its contents on the flash, as I did not know how to. Now I pressed reset several times and the process started. Probably I still have a hardware failure, since the USB does not work. When ANDROID appears instead of the logo, the LED lights up inside. Well, on a flash drive too. Then I photographed everything that appeared on the screen. Then I pulled out a flash drive. The screen turned black, the LED inside also went out. I pressed the reset and the automaker logo appeared again. The seller with aliexpress promised me to send the firmware. We'll see.

You need to wait for the first boot up after the update...
Just try it again... and only the zip file should be on the stick, nothing else.
I would format the stick again and copy the zip file again to it.
Switch the unit completely off, put the stick into the front USB behind the screen and power on.
Wait until the update process is ready, remove the stick and let it do the shut down and reboot automatically. That takes some minutes to get all the stuff done in background.
Then and only then do a reset.

And so, I tried to do as you advised. When i turn on with a USB flash drive connected, nothing happens. All the same logo of the automaker. By manipulating the USB flash drive in the connector or by pressing the reset button, I managed to start the firmware recording process 2 times. For the first time, suspecting a malfunction of the USB connector, I pulled the plug out of the board itself, after the message appeared on the removal of the flash drive. But it did not help. The head unit immediately rebooted and again hung on the automaker's logo. The second time I pulled out the flash drive itself. But the result was the same. I found the pads, apparently, this is UART. I'll try to buy a UART-USB adapter and connect the console. I checked with an oscilloscope, there is some activity on the TX connector until the automaker logo appears. Pictures of the connector in the attachment.
So yes, this is UART. There some logs. It seems to me that one of the processors is not working. The one that dual-core ARM Cortex A-72 MPCore. =(
Hey all,
So i have this android 8 Secaine head unit in my truck. Yesterday it booted and failed. It shows try again and factory reset as options. But none of the touch buttons will move the selection. I plugged in a mouse and can scroll up and down but it will not activate either selection. It was working fine the other day. When i press the reset button it will reboot show the navigation software logo then go to the screen i have attached a photo of in this thread.
Any Ideas ? Is this a hardware failure ? Can i use a jump drive to re-flash the mcu ?
Thanks.
Well, there are 2 points visible...
Try again
Factory data reset
Seems you need to try the second one in this case.
It is written in the yellow colored part how to switch and choose.
Yes i saw that but nothing you touch on the head unit will move the selection or allow you to enable it. The touch function on the radio is gone. I can how ever move up and down the 2 options by plugging in my mouse, but clicking on one of the options does nothing.

If you don´t have physical buttons, take some USB-keyboard and use the arrow keys and the enter key.
Going to try that this weekend and cross my fingers. I have a few MCU's that are specific to this model i can try to flash if i can get it to factory reset. Just hoping the hard drive hasnt failed or the Rom is ok. It has been hot here this week.

Just get it out of the car and on your desk, connected to a 12V power supply.
That is nothing which should be done in the car, at least not if it is hot or stone cold.
