Hello,
I bought an android head unit last year with android 6.0 marchmellow on it, however through-out the winter, the mcu became corrupted which caused all of the following issues.
* All factory apps besides the iGo navigation app instantly crash (no radio, music, bluetooth, etc..)
* Nothing can be triggered in the settings menu as it also instantly crashes as soon as you select anything.
* Side buttons no longer light up
* All side buttons no longer work, only the power and volume knob.
* A precious cd stuck in it due to eject not working (factory app).
After multiple times researching a bit here and there over the past few months, I've determined it to be a corrupted MCU.
Head unit is this one:
https (u know what goes here) www (dot) amazon (dot) com/gp/product/B071XXBD9S
"EinCar
Android 6.0 Marshmallow Car Stereo Double 2 Din 6.2 Inch Capacitive Touch Screen Car DVD Player In Dash GPS Navigation Bluetooth Support OBD2 WiFi Mirrorlink"
I can provide more info if needed just have to power it up. j
If I go into the settings menu and look at the about info, the MCU and a few other things are completely blank.
I need help figuring out how to root & flash it. It has a bunch of female end USB, and two micro usb slots.
I've tried doing it from a micro usb, by holding the reset and power buttons but the recovery boot screen gives no options, simply says its updating, then starts up staying the same.
I do have a laptop but have to buy a male to male usb to connect it.
Trying to flash what I think will work with it is called V7.3.2_20171116.202256_KED1-mod
I can access the play store app as well and install app from there which work, just not any factory ones will work.
Any help would be... super helpful
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.

Dear, I found this procedure to root: https://4pda.ru/forum/index.php?showtopic=930058&st=340#entry82160226 .
I can't download the attachment cause I can't login due to Russian.
Did you try this procedure?
Tks.
Hi I cant login to 4pda too, and I doubt this process cause I can't even connect to my laptop (not recognise / no sound with usb)

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
Phoenix Auto PX6 13.6"
Hello, Well.... after only being installed a few days - some crashes - odd behavior - the unit seems dead...
I was changing the "Car type" image per their instructions - basically a new image file with a particular name on the flash root of the OS - reboot - However, I think - almost certainly erased a file when trying different images.
a reboot worked - and the radio functioned. Seemed fine...
However, when I parked - and the radio powered off - later when I started ....................the car - NO screen. (basically a hard reboot)
BT did connect to my phone - so the radio is working somewhat.
I can hear audio
Backlight is on.
Reverse sensors work - and I can hear the audio.
No images.
Reset button has done nothing.
Being a fusion hybrid titanium - I have NO physical buttons. No HVAC, Radio, seat temp, backup camera -etc just a big black slap of glass.
Is a bootable recovery image possible to restore it to factory? Phoenix support doesnt answer - emails, calls - etc.
Hello I have a problem, I accidentally did a factory reset of my ford edge 2012 and when I start it does not have the edge system and I can not control the AC or the radio from the steering wheel, the image of the vehicle does not appear, I need to download the OS from the ford edge 2012, someone knows where I can download the file to pass it by usb. please can you help me please!

When did you have this in your fusion
I'm having the same issue same car
I have an Allwinner T8 which had been working fine until yesterday. It's running stock firmware and unrooted. Yesterday coming home from work it started to boot loop. The radio would come on for a few seconds, then go off, the display constantly shoing the turning android.
I had hoped it was just hot as it was a very hot day, but was the same this morning. I've tried pressing the reset button to no avail, it just no longer plays a radio station as it's lost the stored stations.
I cannot seem to find a way to get into recovery mode, tried plugging in a USB keyboard and pressing "i" and CTRL-PrintScrn but nothing.
Can anyone offer any advice before it ends up as landfill?
I have the same problem with an Allwinner T8 team.
I have a 2016 jeep renegade sport plus. Supposedly the android team is a winca S300.
And it was in a loop, it does not start the system and it stays in the android logo.
I saw a way for the system to update itself.
1) the key must be connected - without starting - just making contact - power -
2) when the device reaches the android logo, it must be reset.
3) When the equipment is restarted, before the logo appears, the ignition key must be turned and removed.
4) After that, the start key must be reconnected. This should bring up an update banner.
The problem is finding that software, which should be previously installed on a flash drive.
Does anyone know how to get it?
Sorry in advance for my bad english, I actually speak german and translated it
Hello, I bought a new used car (Honda CR-V 2006).
The previous owner installed a Junsun V1 Pro display.
When I test drove it, it all still worked without any problems, but the previous owner completely reset it before selling it and that's why I now have probable following problems.
Problem 1:
The buttons on the left side (not on the touch screen) do not work, nothing happens when pressed and the buttons also no longer light up.
Problem 2:
There is no longer a T-Link app in the menu and therefore CarPlay no longer works. I have looked through every menu setting but have found nothing.
More info:
In general it seems to me that the software is not complete, there are some items in the settings that seem buggy. When I want to make a software update via USB, no confirmation button comes, when I want to log in to the developer menu, doesn't happen (I already tested all possible passwords from https://forum.xda-developers.com/t/junsun-v1-codes.4282299/).
The steering wheel buttons work, I can turn the music up and down and also change the radio station.
My solutions:
I have already tried to make a software update via the internet or via a USB stick, both without success, via the internet it says there is no new update and with the USB stick there is no confirmation although the stick is recognized by Android.
I have also tried to reinstall the software with a USB stick but there is no installation popup, although the USB stick is recognized.
I have also tried downloading the T-Link app via APK, which all worked, but as soon as I try to open the app, it crashes.
I'm starting to get desperate because 2 days ago this all worked, but since the reset it no longer does.
Do you guys have any tips and solutions on how I can fix this?
Hello,
After a factory reset I have the same problem 1 of you. Unfortunately I not have find the solution, but the buttons is not on all headunit those junsun add by activation menu or by an apk this option.
Finally the solution of problem 1 is remap the button in factory menu 8888.
Thank you, it works now!
