This is an Allwinner T3-P3 unit (Quad core).
No "hardware buttons"on the face. Touch screen with side bar of non-mechanical buttons.
I am trying to get a different MCU on it as the one I have will not work with the radio or Aux Input.
So, I managed to load a rooted/moded rom and have root access.
The "upgrade start" screen flashes by and won't recognize a 64gig Micro-SD in the GPS location no matter what the format (extfat, NTSF, FAT32..nothing).
Phoenix boot doesn't seem to work or at least not with this card and the img files I have (img will not load in phoenix).
Doesn't seem and IMG file is recognized by the system either.
Also tried an 8gig USB stick on the external USB ports (marked USB and USB DVD).
I can get to the ADB screen (from recovery) however, it will not connect with any of my computers (2 of them one Window 10 and another Windows 7). Many drivers installed but the PC
will not see the Eonon GA2163. Device manager shows nothing connected/recognized.. no "!" either or "other" device.
Help, please.
Forgive me if this beginner posted improperly.
Hi all,
I brick unit 2 days ago after bad flash with Mekede Root.img via SDCard and now unit start with black screen, I only hear the cd running 2 sec and nothing else.
Problem on this unit, I never had USB connexion with my pc or my Samsung device (on each 2 slots) when android was alive, so now it's bricked, I opened unit and I'm searching everywhere.
When I plugged USB on pc without 12v, I hear CD inside. When I start with 12V + acc, it's the same, but nothing and black screen.
I installed all drivers MTK from the web lol nothing. I tried to solder a USB cable on USB that goes to the CD in parallel (because I hear something so it's working) but no success. I have 2 pc, 2 different cable so it's not related, I tried all combinations with button / reset (10 sec, 30sec etc).
I tried this from Jacotreus here : https://forum.xda-developers.com/an...its/how-to-enter-recovery-mode-t3280247/page2 no success too, but that was obvious because no recovery ..
BTW when I plugged sdcard with .img / .upd / .bin, nothing works
Where could I watch to activate this damn USB ? is it really impossible to do something ?
If someone can help, thank you :good:
ps : I bought this unit in second hand, so I can't contact seller. it will end up in a closet so I can hack it
Hi, did you manage to connect to the head unit, I have the same problem, cannot get it to connect to the pc tried test point method still doesn't connect!
Hi no I didn't. I bought a new unit PX30 rockchip witch is not seen either by my pc... but it's working so I don't touch anymore.
My AC8227is still bricked, hope to find how to solve one day
Hi, I know how to get the unit to connect to PC but have no correct rom to flash. Do one of you guys have the rom for this unit?
hello, you can explain to me how you did it
Hello friends!
I bought an Android Head Unit MIB4 (SC9853I) for my VW Golf 7:
https://www.alibaba.com/product-det...l?spm=a2700.7724838.2017115.25.71201862OEMWlE
Everything works fine but I'm having problems with the USB ports.. the 3 usb ports charge my phone but they don't read any usb drive with music. I don't know if this is a hardware or software problem.. I've tried formatting several usb drives (4gb , 1gb, 64gb) in fat32 but none of them are read by any usb port of the headunit.
Please, help me! and thanks in advance..
Hello, please help with updating and where to download new software for the above-mentioned radio. Chipset AC8227L, 1/16 GB. I downloaded programming from https://forum.xda-developers.com/t/help-with-this-chinese-hu-alps-8227l_demo.3930394/ ; every time ith throws an error to let me check the usb and files. I changed 3x USB stick and memory cards, each time the same, FAT32 format.
Hi, format SD card possibly greater than 4GB with standard settings - FAT32 or ExFAT file system and deafult allocation rate.
Next, download one of firmwares that suits your device (for 8227L it has a lot of them on this forum but your device maybe have different UI than XPH.8227_8_xxxxxx mentioned in this above link).
In my oppinion the ones that will work for your model begins with XRC,CHS, JC.
Firmware for download are like this example : CHS.8227L-8.UI4.Android_10_ver.6_xxxx(date of update)
After download and unzipping two files, .bin and .upd transfer those two files on freshly formated disk, nothing else just these two files. If transfering from PC or laptop make sure that you eject the drive before pulling out from PC.
Next step is to make the unit recognize system on SD card. Put the ignition key in contact mode or better turn engine on (before that insert SD card in memory card slot, not MAP slot !) and start tapping with one finger on center on screen untill message DETECTED is seen on upper screen area. If successful it will recognize files and start automatically updating (wait till finishes and enters system / UI), if not or fails to recognize files for update repeat process two or three times untill successful.
If still nothing, enter erase mode / recovery mode (purge of internal memory and files) by tapping with all five fingers on screen. When recovery is completed (it will turn to factory settings) device will be empty of all memory tasks, prevoius configurations etc. , just clean install of Android system, running and with no apps and settings configured. Then insert SD card and try update again.
If device even won't go in recovery mode then you have some factory settings like "protection" or "install" enabled. Turn this off both in factory settings / menu OTHER.
Good luck !

It's on forum here just type in search bar 8227L firmware and find best choice for you. If not found wil send you a link.
Sorry but I am not able to find the latest software compatible with my radio, there is too much of it, please help.
I will add that my radio does not have slots for SD cards and Maps, there is only a female USB input to which I can connect a USB flash drive, the device is fully touchable without buttons.
it is probably a Chinese counterfeit I bought on aliexpress, there will be a problem with the selection of the update
Similar firmware to yours is here https://drive.google.com/drive/folders/1a9yoWoiuMZRoQVL5O677Y9tmQHHAtmbo
Try to install this one it is TSKJ/CHS UI firmware for devices with 8227L chipset.
Extzract and put downloaded files onto USB drive formated for FAT 32 and try updateing.
memory formatted in FAT32, tried for two different, only two files extracted, each time in green DETECTED and after a while in red "Fail, please check USB and files", I tried several times
restoring the settings with a five-finger touch also did not work
I deleted the data to the initial state, but the update still does not start
I noticed that if I detach the USB and I make a finger movement during startup, the symptom is the same, as if I would not see the usb
Do you have install option in factory settings disabled ? Or protection option ? If do deactivate PROTECTION and enable INSTALL in factory settings (pin code) / OTHER submenu. Then try updating again.
yes, I have it done, I also entered the pin, unfortunately unchanged
Use another USB drive with 2.0 speed not 3.0 if this is the case.
Maybe it's just some stupid thing like this that is keeping you from updating.
If this not succesfull either check your device usb ports if they are working thru USB debug command in factory settings, also turn on all USB to be 2.0 and not 1.1 maybe will help somehow. I think that USB port is missconfigured and are causing not to update.
Another thing , if you have by hand any SD card and USB card reader try with that.
I have debugging turned on in the settings after entering the code 8888, and the USB is switched to 2.0, I tried with a new pendrive and with an SD card reader that I put into the USB, unfortunately still unchanged, I also changed the USB input on the back of the radio by switching the cable

Hm, this is a hard one, has this unit of yours been rooted ?
Honestly, I don't know how can I check it? how to root?
If it turns out I have root, does that change anything?
Install from Google play any app that contains root tester and see. Yes if it is rooted device is modified and altered and do not have stock firmwares, which leads to undesired complications and problems.
If the device turns out to be root, it is possible to work around it in some way to install other software?
I checked, the app showed that my device does not have root
today I bought memory 2.0, but still unchanged, these are my settings, is everything ok?

Hi all,
Trying to update my Junsun headunit with 8227L_8军灿UI03-国外11_v3_20220714 however when plugging the USB into the unit, it won't boot/recognise the .bin & .upd files.
I've tried both USB ports, both ports read the USB, and I can access the files on the headunit through file explorer, however whatever I try I can't get the unit to boot the update.
I've attempted to reset the device using a pin in the reset hole, and also tried with the unit off and turn the key but the unit just boots normally - nothing seems to be working. USB debugging is turned on in developer options.
Any suggestions?
Platform: 8227L_demo
RAM: 2gb
Storage: 32gb
4 core
Did I read somewhere that you need to rename the files to remove the Chinese characters before they will be recognized? I could be wrong but worth a try.
Hi I don't know if this is the right place for this post, I'm new here.
I have a problem with my Junsun V1 PRO, it does not detect me the USB, in hidden configuration of the radio, in the code 8878, and in the Others section, I do not see the USB, instead there is Ihone-Eth ????
Are there any forum members, who have the same thing happening to them?
Could it be a firmware issue?
As it does not detect me, or not having the USB option, I will not be able to update a future higher version of the firmware.
The USB cables are well connected, I have tried with the two that came with the radio, and also another adapter to use the original USB of the car. With none of them the USB option appears in the hidden menu of the radio.
My car is HYUNDAI TUCSON 2015-2018.
