Hey Guys, I bought this chinese head unit and it was working perfect unless it started lagging and low memory message started appearing on the screen. I have tried factory reset and clearing memory how ever possible without root access but I am unable to clear dalvick cache.
There is not option to reboot to recovery without root, I have tried many hard keys combination so far nothing has worked for me.
There is an option to update ROM via update.zip file. So I was wondering if it is possible to have an update.zip file with instructions to reboot into recovery. if that is possible can someone please share a zip file that I can use for this purpose?
looking forward for support from the community. Cheers!

Did you get anywhere with this?
Hi,
I have the same problem and was wondering if you got a solution?

Is your HU a Joying? PX5 or Intel Sofia?
If your HU does not have any physical buttons, you could go in to recovery by restarting/rebooting the HU and connecting a keyboard to the HU USB port and pressing Alt + Print Scr + tapping I

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.
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!

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, 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
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

Hello guys. First of all, I've been searching for weeks for any similar situation with mine but couldn't find anything. I have Unbranded Chinese Android Head Unit running Android 4.2.2. with physical button and a reset pin. I tried tonnes of ways to get to the recovery with any possible method and nothing seems to be working.
can anyone show me how to get into recovery or force hard reset on the unit ?
I have attached a few pictures of the Unit info and the circuit board.
i tried to connect a USB keyboard to my Unit and pressed PrtScr + "E" but my unit did not show factory rest option. you can see what happened in the attached video
i will be thankful for you, if you tell me how to get into recovery mode of make a hard factory rest or install a new ROM.
Thanks in advance .
