Help - Unit on loop...

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.

Ownice C500 OL-6666G Boot loop

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

Skyline android Head unit

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!

Boot loop can't factory reset - softkeys only

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.

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

Suzuki Grand Vitara - M779 Head Unit PX5 Octa Core - stuck on Bootlogo

Hey guys,
I bought a Navigation System M779 (androidautoplayer.com) for Suzuki Grand Vitara from AliExpress one month ago.
At first, everything was fine and I was very happy about it. Nothing to conplain about.
Then I went on Holidays for about 14 days, in which the car wasn't used in any way.
Yesterday I started the car for the first time after Holiday, the battery still was fine but the radio did not boot. The screen stayed black and the Buttons did not light up.
After checking the Plugs on the back, the screen showed a Bootlogo, but got stuck.
I did not modify anything and everything was fine until Holiday.
Can you please help me?
Pressing reset did not change anything. Sometimes, selecting reverse does activate the rear cam. That's it.
I don't know how to enter Recovery or how to install the Firmware.
It is an Android 9 PX5 System. This is everything I know.
Kind regards
Robin

May be able to reflash firmware using this method - https://forum.xda-developers.com/showpost.php?p=79144579&postcount=2 assuming that the manufacturer posts firmwares on their site, or can provide it to you via download, email, etc.

Thank you for your reply.
I tried some Firmware-files, just to see If the head unit enters Recovery. This failed.
The manufacturer also replied to a Mail, telling me that they will hand me out a possible solution next week.
I will wait eagerly.

Hallo again,
unfortunately the manufacturer did not provide a solution to recovery my Head Unit.
I managed to get into the Recovery Menu and tried to wipe data, but this had no effect at all. Still stucking in bootloop.
The information given in Rcovery Mode are:
rockchip/rk3368/rk3368
9/PQ2A.190305.002/hct204281503
userdebug/test-keys
Recovery V9.0.5.
Supported API: 3
Can anyone please help me restore the Head Unit?
Kind regards

Did you try to disconnect the main connector from the unit and leave it that way for a few minutes ?
And then reconnect it again.

Thanks for your reply... But I think I did very stupid today and bricked the device.
Reagrding to this topic "forum.xda-developers.com/android-auto/android-head-units/head-units-rockchip-px5-mcu-csn2-t3912413" I flashed my device with "Fake Android 10 - July 6th 202007061156".
The flash ran smooth without any errors. But the screen seems dead now.
The buttonlights still turn on and do blink if I press the powerbutton for about 10s, but there is no bootlogo or anything at all.
I cannot enter recovery anymore.
**** happens?!?
Kind regards
Fisatec
