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 all ,
I am facing a problem with my Joying Head unit JY-VL130N2.
I tried to update the system from website with the latest file ( carjoying.com/blog/joying-head-unit-after-sale-support/59.html ) , but unfortunately the installation was not successful , message coming that "System has not enough space ". Please see below photos .

I tried to reset the headunit through the small button on the right bottom side , unplugged and re-plugged the USB stick , same message after. Tried as well with three different USB sticks (FAT32),same thing . I wrote a few emails to Joying support team , but no success until now as they keep telling me to do factory reset and then update again , which I cannot do it as the system does not load at all.
Can anyone please help me to solve this ?
Many thanks
Do you have lots of 3rd party apps in stalled? Do full factory reset and internal storage clean, then repeat flashing FW.
See edit's FAQ thread for details:

Hi ,
Can you please tell me how to do a factory reset and internal storage clean as the head unit is not loading into Android system ? Many thanks
Oh, that...
1. First I would leave HU ON, maybe pressed reset and left (no sticks in USB). There mighg be a chance of magic self recover happening after several unsuccessive boot.
2. While performing step 1, I would search this forum for some key combination/long reset press or something of this kind followed by purple text output - only today have seen this instructions here or on carjoying forum, but can not find it again.
3. Continue to press Joying team for a solution.

1) like ste2002 says: be patient. It can take 20 minutes, but that is in case your system is correct but had 3 unsuccessful boots. But in this case when the unit already mentions that the update was unsuccesful, it will probably not work, but it is always worth a try as it is the "laziest and easiest" method.
2) The reset option is with a "pointy" thing in the reset hole until the boot logos appear. Then reset again. After 3 uncompleted boots this early in the process, the system will go into the recovery boot, which are the purple leds. Use this purple led boot to connect at that moment your usb stick with the firmware.
Have you tried to re-download the update rar file again? Maybe it got somehow corrupt.
How big is the file Allapp.pkg? It should be 302,066 KB (~295 MB)
In case this does not help...
You could experiment with contents of file SQLSOFIA.
Since Feb 2017 it contains
Code:
mass
twipe_all
#make_updates
Before that it contained only
Code:
mass
No idea if this could help to make sure that the system partition is reformatted before the content is written there.
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
Beers for anyone who can help!
I have Pumpkin ND0294B-A08, was trying for hours to get root for it, at one point an APK loader was supposed to root and reboot to recovery mode, it looked like root was successful but never booted to recovery, now I am stuck at either straight PUMPKIN load screen, or if I use RST button along with POWER button I can get it to "Starting update..." screen with android logo.
I have been working for hours and keep hitting dead ends and broken links and files that are missing from download sites and am now just stuck.
Unit is Android 8 PX5 MCU CSN2. I thought it was the same as my last head unit but I overlooked the MCU CSN2 and I think that's why it's dead.
Beers for anyone who can help me bring this back to life, extra for those who can help me bring it back to life rooted.
Thank you.
From what i remember from other posts is you can flash the standard (CSN2) firmware without booting into android. If you can get it into "starting upgrade" mode, try having an sd card in there with the stock firmware. Easily downloadable from the csn2 thread. I hope you have success!
I actually tried that once or twice just to get it back from being bricked, and it wasn't working. EDIT: found many extra links for firmware. I will try again.
EDIT 2: tried UPDATE2.BIN and KUPDATE.ZIP in a fat32 SD card that worked earlier on this same unit, tried several versions of the factory firmware from the thread and it isn't working for me. If I just power the unit with the SD card inserted, it sits at PUMPKIN large letter screen. Not in a loop, just sits at that screen. THEN, when I boot while holding power button it shows a display with a green Android character with the words "Starting update..." but I let it sit that way for an hour and it does nothing else.
Anyone else have ideas that can help possibly? My unit is bricked unless I get this fixed.
Thank you,

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.

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
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?
