[Big Issue] Allwinner T8, 2GB/32GB, 7.1.2, 7" Resolutions issue - Android Head-Units

Hello Brother's,
Could you please help me ,
i have 2Din Bonroad Octa-Core Allwinner T8 7 " 7.1.2
I made some changes on the resolution , i change it from 1024x600 to 4K from Develop settings in the Menu ,
just after this change i lost the control on the touch screen , and i can't change to original resolution or any another operation, also with external mouse :crying:,
i tried to update my 2din with more than 10 Upgrades , but still same issue :crying:,
i tried to made hard reset , but i can't find how make hard reset in this model , i tried to click on the power boton and reset boton for reseting , but without any result :crying:,
i tried to unplug the battery for 30 minutes also nothing !
i search in the many forum's and many Video's in YouTube , no result :crying:,
possible to help me brother's :crying:
Kind Regards,

Did you ever figure it out

If it is anything like my unit, if you try to change resolution in settings, you get a message saying something like not to do it but you did and it doesn't matter what you do, it is now probably a door weight. So take note of any messages on screen before doing something silly.
By the way, can I offer you a tissue?

8227L android unit 8.1 chinese

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)

I had that problem with USB and my laptop... I had to enable it in the 8888 settings. I dont remember the actual name of the setting atm but check my stereo later and let you know.
Try and post result please.

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

Hi, Ive been using your same head unit with Car Launcher Pro for a few months now. Its my 4th attempt at a double din retrofit and its easily the best so far. I too had radio problems. After I installed Launcher and tried it out I was so thrilled that I proceeded to load it up as I would a tablet.
Suddenly, I launched the radio and the bottom row of function icons were gone and the lower half of the presets were also gone. I reset the unit back to factory defaults and started over. This time, I just loaded Car Launcher, Maps, and Spotify.
everything is working great and appears to be rock solid so I am testing it all on the bench before I install.
I don't know what corrupted the Radio app.
If anyone has a recommendation for which Double Din Android head unit is considered the best, I would really appreciate it. So far, the Alps 9212 is easily the best build quality and best performance so far. I have to use the speaker level outputs feeding a line converter because the 9212 has no rear line out. connections.

What do you mean "the best"? 8227L_demo (device name in settings) is just rubbish, based on ancient processor. Any PX30, PX5/6 perform much better.
Good day! Please help with the firmware, I can't find the current firmware, more optimized and with a better interface. I have android 10.1, version 9212B. Kernel version 4.14.116. I will attach another photo. I will be grateful for your help
