8.1.0/011019/1571038753
I purchased a Chinese HU off of Ebay (a Witson, DKS9625)and it's been working pretty well for the past few months. I went to turn my car on a couple of days ago, and it gives me the error "Can't load Android system" with the option to Try again or to Factory data reset. The thing is, I can't move the cursor down to factory reset because the Power/Volume +/- keys don't work.
AC8227L Quad-core ARM Cortex-A7 4*1.5Ghz
Witson, DKS9625
witson.com/en/displayproduct.html?id=3121437840622976
How do I get out of this bootloop? My softkeys don't work so I can't use Power/Volume +/-. I've tried plugging in a usb keyboard and a usb mouse but nothing is detected. I've tried cutting power completely (remove the battery) and that doesn't work either. The screen shown seems to indicate that this is Android 8.1.0 but I bought it with Android 10. Is that just a marketing thing due to it being Chinese? Do I need to reflash this unit and with what image as I don't have the original MCU. Is there a WIKI or a how to somewhere that would help? Thanks for all of the help.
Have exactly the same problem, i tried to plug a keyboard but not detected..
If someone have a issue please help

Hi
I recently bought a Joying UMS01N2 - 2GB 7" Single Din unit... I had previously posted about recommended upgrades, and was successful in doing some basic mods...
I changed the boot logo to a custom , and was then playing around with the bootanimation.zip file to get a custom boot animation (duh)... however, I may have messed something up because now the unit starts, shows the custom boot logo, and then goes to a lit black screen - almost as if in an endless loop... it will not load onto the launcher/app and stays as a black lit screen... I have tried to recover by restarting, and long/short pressing the PWR and RST buttons, but nothing is allowing a reboot/recovery...
Any advise?
I am running Android 6 as per the latest factory ROM (unit received in August) - not updated in Sep to recent update posted on the joying page
Thanks!
I would try to make a "blind" reflashing by attaching flash drive with latest FW.
How exactly is that done? Thanks in advance
Just connect flash drive containing unzipped FW files. Optionally do a soft reset with a toothpick into RST hole. Then wait. Hopefuly reflashing can wipe those boot animations for good (which I am not quite sure of).
As to me, I can not see any point in installing boot animations which under normal conditions one is not going to see on his/her HU screen ever. Only if something wrong happens and some sort of reset performed. Good reminder would be to me what a "beginner" I am
*Needless to say that USB flash drive should be error free irrespective of formatting option.
Would you not see the bootanimation every time the car is started? I say every time since I will probably only drive once a week (weekend toy) and I believe the Joying unit shuts down within 3 days of going into standby...
I will try to reflash using a USB... will post back if I need any further help... Thanks!
It worked!! Thanks!!!
I was able to reflash with a soft boot using the Sep 1 firmware... all my old apps are still there, but I will test them out later... for now the only issue I have is none of my left panel buttons on the screen are working anymore? I have a single din detachable screen with a column of buttons on the left side (power, home, nav, and volume)... and none of them respond to touch?? Is there a setting I need to adjust for this?
There is in settings - something like MCU HW buttons (do not remember exactly, may not contain "HW", but does contain "MCU" and "button"). Should work.
Hello,
It's my first post here, but I've allready read and found many informations on this forum. I'm french sorry for my english !
I have a big problem with my Ownice C500 OL-6666G : Few days ago, when I was BT calling the unit has suddenly stopped and reboot. Since this event, the unit is in a boot loop, it restarts, show boot logo then black screen for 15 seconds and then restarts, etc. I've made a video : h t t p s ://we.tl/t-7buTPOl1NZ
I have search for similar problem but found no solution.
I have tried to :
- Access recovery, but it doesn't work. I've tried many combinations of power button, reset and screen touching... Nothing works. It's only indicate in green "detected" at the upper left corner when boot logo is displayed, then black screen and reboot ;
- Launch a firmware update through USB and SD-Card, same problem, it doesn't launch, it's only indicate in green "detected" at the upper left corner when boot logo is displayed, then black screen and reboot. I've tested many firmware found on this thread : h t t p ://forum.carpad.vn/threads/huong-dan-chay-firmware-dau-owince-c500.23. I've tested 3561s and 3562s versions. I've tested the different USB port and remove all accessories (USb and SD).
I've done many search and maybe there is other solutions, but I need some help :
- Access recovery in order to wipe data or factory reset. But what is the procedure to access recovery on C500 unit ?
- using sdimage like C200 to force firmware update. Unfortunately, I have not found any sdimage for C500. Is this method also compatible with C500 ?
- Using USB cable to connect a portable PC and launch firmware update with RK3 firmware tools (or similar for C500), but I'm not sure this will work since the unit is continuously rebooting ;
- Unlock the bootloader, but I've found no information for ownice unit...
Thanks in advance for your response !
to factory reset:
reset the unit with rst buton, then tap tap the screen with 5 fingers. hope it helps
or when you put the usb with firmware on it, reset the unit with rst buton then slide one finger in the right part of the screen in up/down motion
Hi everyone,
I hope you have experience with mentioned head unit and could help me with the problem I have.
Mine head unit is running Android marshmallow 6.0
And was working without any problems until few days ago when it went into a boot loop.
I have tried many options mentioned on this and other sites but I am unable to recover Android installation. It doesn’t go into the recovery mode with any combination I have tried, reset+power button.
Only success I had to get into recovery mode is with the usb keyboard, and alt gr + pr.scr. + I combination. This way I can boot into recovery but problem still remains, when menu pops up keyboard stops working and I can’t navigate through the menu, buttons on hu are also not responding.... I have tried different USB ports, also tried to navigate with the mouse but I am still stuck here...
So what could I do? Any advice will be so appreciated!
Hope someone can help. I have an Android 8.1 head unit (Chinese) which has been working fine. I removed it from my car and powered it up in the house with a PC PSU, this enabled me to sit for a few hours and set all my apps and home screen up just as I want it. Once all was done, it was running great. I installed back in the car and on powering up, everything was good. A couple of days later, I got in the car and the android displayed “Erasing" and took about 10 minutes to boot. On boot it has gone back to factory defaults and deleted everything. Even worse, the original launcher screen will not come on and it just says “Starting android" but does not progress any further and I cannot get into any settings.
Does anyone know -
1) How to access recovery mode, either by the reset button combination or taking the motherboard out and shorting?
2) or How to Install the original or another Android that will work with my unit?
Or any other ideas? I'm fairly confident when it comes to fixing stuff, just need a walkthrough to get me up and running again.
I had the same issue after installing a new firmware in my Junsun V1 Pro with Mtk8257 CPU. Unfortunately you're just writing that you have a Chinese head unit but all Android head units are from China...
This happened only once and after configuring everything again I have no further problems. The "Starting Android" screen appeared several minutes. So still stay patient and wait.
I thought the erasing happened because I remounted the vendor partition for write access in a wrong way. Maybe you installed a software component or performed some special actions which may be the reason for the erasing?
Dear users,
this is my first post since years here and I really need your advice. I recently acquired this headunit here:
Loading…
de.aliexpress.com
Its called H30 Plus and its an Android 12 12.3" inch head-unit for my W176 A-Class Mercedes.
In the beginning it worked fine, but after a while (and a reset) the screen stayed black - even the boot logo didn't appear (also after a power-disconnect). But the system itself is working, because if I press the "return" key on the original car's command wheel, or if I activate the backup camera the system shows my NTG 4.5 original system on the screen.
--> It just doesn't switch back to android.
On the side of the radio, there is a RST button, but it simply restarts the headunit. The seller ignores and doesn't want to understand my messages, so maybe I can get some help here:
1) Does anybody know, where I can get the firmware for this device?
2) Is there any commonly known methods how to re-flash these units (especially this one)?
Please help me out, because in working mode it is a really nice system and I want to try as much as possible to recover it!
