I have an error android head unit and have found a way on how to fix it from the other thread, "Need Help To Recover Bootlooped China Head Unit (Android 8.1 Go) AC8227L" started by Azmil2307, here on xda.
I have followed the instruction such as installing mediatek vcom driver, flashtool, male to male usb, firmware, but the problem is the PC still could not detect the head unit's USB connection. When i connected it using male to male usb, no connecting sound at all.
Do you guys know whats the possible solutions for this problem?
thanks,

I opened unit and saw where the 2 usb go but I do not have enough experience to go further :silly:
I tried to connect directly to the cable USB dvd but my pc still does not detect, dvd makes noise when connected so it's powered, but no DATA goes to the computer
Any resolution to this, i have the same issue. I also cannot get an adb connection via wifi. Any help or knowledge on why this is happening would be great.
Thanks.

Hey all,
Has anyone been able to successfully root from a MacBook Pro 2016 with USB Type C ports? Having problem getting adb to list my Shield. This is on:
2016 Macbook Pro w/ macOS Sierra 10.12.3
WAWPI USB 3.0 A Male to A Male Cable
Apple USB-C to USB Adapter
Android Debug Bridge version 1.0.36 (Revision 84e3321d5db3-android)
System Information -> USB shows Shield but adb devices does not. I was able to connect with adb connect <IP> but not USB. I've seen various threads pointing to a possible issue with Mac USB Type C/Thunderbolt 3 ports.
Any help would be appreciated.
EDIT: adb command works with about mentioned cable and adapter. The real issue is fastboot. It constantly freezes/crashes macOS. I think my Mac was in a funky state preventing adb command from listing devices. Unfortunately, this still prevents me from performing a complete root from this macbook. I was able to complete root with another macbook with USB ports. So does anyone have a fix or workaround for fastboot other than running a VM or bootcamp?
EDIT2: In case anyone is following this thread... There's an open bug for this and a fix is in QA. New release coming.
Thanks for this post.. I was confused about what the issue was.
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

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..

Did you try to change your USB Connection setting from 'Charging' to 'File Transfer'?
Also, if in case you're using a cable other than the provided USB-C data cable, are you sure that it's a data cable and not just a charging cable?

I already tried usb debugging on, with file transfer/charging and debugging off with file transfer/charging. and I'm currently using original usb c. I always get this error saying that my device must be updated first (see attachment) , but I already at latest miui. I even formatted my windows lol, still no luck. But I still can transfer file between my pc and phone using windows explorer.
I have this Eonon Ga2168SR head unit, which has only USB Type-A male connectors. I got a USB type-A extension (male/female) and it works just fine when connecting cameras, flash drives, keyboard and mouse but when I try to use it as a connection with my laptop (male/male) no new device is recognized (device manager on windows and lsusb command on linux). ADB works just fine on wi-fi though but I need to flash firmware in fastboot mode.
I couldn't find out if the problem is the cable, the firmware that blocks this kind of connection or whatsoever. Has anyone had success on this?
I can post pictures of the unit's board, if required.
Thanks
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.
