There is getting to be quite a bit of information to look through when looking for tip/solutions related to the new Joying 2GB / Sofia units. Since this is not a MTCB or MTCD unit, the threads seem to be scattered all over and very difficult to find in searching. I have seen roll-up threads for other units, that contain information such as ROMS available, tips, tricks and useful information. Kind of a "one stop shop" for the newer Joying HUs. If you have useful software, mod, tips, customization's, get something to work, etc please post here and I can include.
CPU Information - Rockchip Sofia x64 C3230RK / mali 450 GPU / Up to 1.2Ghz / 4 core / FYT5009 SoM - rated to run at up to 85C. My particular is unit clocked at 1.04Ghz.

https://forum.xda-developers.com/an...d-units/joying-intel-update-feb-22nd-t3561285
People have experienced issues with the Joying Launcher (UI3) after the update. This seems related to having other packages (google voice search ) installed prior to installing the ROM. Install time 25-35 minutes.
Recovery from non-bootable system - Without being able to access recovery, about the only solution is to reload the ROM package. Unzip ROM to SD card or USB stick, put in unit (GPS Maps slot, if using SD card ) and press the 'recessed' reset button. The unit should find the update and reload the ROM. This will wipe your data, but does leave the apps. If you use titanium backup, and have a backup, you can restore your data fairly easily. See blog article above for step by step instructions.
Root - Unit comes with root accessible in adb. SuperSU can be installed easily. There are 2 methods for installing superSU. The first method is an overwrite of the boot partition with a pre-rooted image. Problem here is if future upgrade makes boot partition changes, this method will overwrite with an older version. I recommend method 2, which modifies the existing boot partition ( need source so I can provide credit ).

https://drive.google.com/file/d/0B4qmTV7N4JliSjZMdGg3Z18wbkU/view?usp=sharing ( modifies existing boot partition )
OS & Google Apps - Android 5.1.1 ASOP based w/ pico installation of google applications. Voice actions are supported with installation of 'Google App' from play store. No support for google search talk back.
Recovery- A recovery partition is present but does not have any type of graphical UI. It does look like a complete stock android ( command line ) recovery, but no access using USB is available. It maybe be possible using PC-PC OTG cable.
SD Cards - I have not heard of any sdcard size limitations, up to 200GB have been reported to work. Must be formatted as FAT32. NTFS, exFAT, and ext3/4 do not work. You can format a USB stick with ext4 and it will work fine.
Google Voice Calling - Stock BT dialer crashes when being called from google applications ( such as google voice search ). Workaround is available.

Apps not working after resume - The joying code will kill most applications when going into standby. This is really bad for apps that are supposed to be run at boot and background process, as they are not restarted when exiting standby. Symptoms include, widgets not updating, apps not getting GPS lock, process show running but background services are no longer running. This can be fixed by installing an updated apk file in /system/app/Sofia-1-C9-Server-V1.0 which removes the task killer. Also the key/button mods V2+ (below) will remove the task killer.

Yes this is really needed. A FAQ with overview links and tips in just one post
Some people mentioned it was possible to boot into a restore function from a memory card with the update zip. If true, do we know what the exact process is? Any keys need to be held down?
Update, verified this procedure works:
sonof said:
I did recover from endless Android logo (resulting from trying to root with Joying HU root.zip found in this thread).
I did the following:
Put latest Joying update files to microSD card and insert it to GPS slot. Press and hold both reset and power buttons. Once it boots continue holding reset button.
This lead to automatic install of Joying update files and my HU was back alive but I hate the Joying company for not providing means to enter recovery and a complete ROM.
Edit: For me it did not ask if I want to update or not. It just began updating automatically. In contradict to the post above. But I was unable to boot to Android when I tried this.

My VW has reverse parking sensors. Does it not support those?
Just installed this unit. Speedwise it's night and day compared to my old Erisin (1gb 3188). Display is nice and crisp. Bit of a fiddle getting it mounted because of all the crap that needs to be stuffed behind it, but after some swearing and elbow grease I got it secured.
From the instructions, I cut an orange wire because I don't have a backup camera. I do however have optical parking sensors. On my Erisin this was supported (it showed a car model and visual indicators on screen). This unit doesn't appear to have this function. Can anyone confirm? I still get the beep from the speakers, so it's not really a big issue, but would be nice to know.

I'd like to work on this one.
But I have two questions;
1) did you manage to get any logs of how it failed?
2) When you made it unbootable, what was the exact procedure you used to recover the unit?
Click to expand...

I didn't get any logs, as I couldn't connect to it until I reloaded the ROM. If I was able to make a USB connection, at least I could have looked at the logcat.
Procedure to recover: Insert USB drive with ROM, push recessed reset button, wait 30m for ROM to install, set up apps again. I have this procedure down pretty good. - The joys of playing with the system partition without USB access or recovery tools.

Actually, it turns out it does, however only when there's an obstacle (hopefully we can change this). Yesterday I only tested while stationary. Today I used it while driving, and noticed that whenever the sensor picked something up, the unit does actually display the sensors. It feels next to useless for me when it only shows on beeps, but at least we know it's there.
Well, that is the way my discarded Newsmy worked. Takes getting used to, but you then again you don't really need confirmation that "nothing" is in your way
Will need to think about this then, thank you.. Cant make up if I want this or the Ownice C500.

After updating to the January firmware parking sensors are gone completely.
edit: enabling "radar" is the solution
Installed supersu (like described in this thread) yesterday and updated it from the play store. Worked fine.
Then I installed Viper4android, also from the store. I didn't expect it to work, but it does! Driver installed, and after a reboot it does exactly what it's supposed to.
Also installed Nova Launcher and set as default home. No issues with that so far. I have not frozen or uninstalled any of the original launchers.
On my Joying unit 130N2 (8 inch unit for VW) the backlight on the display does not work when it is cold. We had minus 8 degrees centigrade here and it took more than 10 minutes before the backlight came on. The radio is playing music and it is actually possible to change channel as long as you know where to touch the monitor. Today it was 5 degrees and it took only about 3 seconds before the backlight came on. I wrote Joying about it and they confirmed to me that there was an issue with 8 inch models for VW. They told me that they were working on a completely new firmware that would fix the problem. I told them that to me it seemed to be a hardware problem and how they wanted to fix that with a software. Their answer of course "No worry my friend ......". I told them that I wanted to return the radio because a radio that doesn't work when it is cold is useless to me. They told me that I would have to send it to China so that their engineers could investigate the problem. I then told them that I had bought it from a German website and it was delivered to me from Germany so if their wanted it to be sent to China then they would have to pay me for it - in advance. They told me that their warehouse in Germany did not accept any returns so it was impossible for me to return it. Then I opened a case with Paypal for selling defective merchandise. Then suddenly their warehouse in Germany was accepting returns. I had put this text also on the Joying Forum, but of course they deleted it. So when dealing with Joying and in case you have problems my advice is to be very tough on them otherwise they will BS you.

I have the same problem on the same unit. With the car headlights off, backlight is dim when it's cold, but gets brighter when it has time to warm up. And when the headlights are on, the backlight isn't on at all until it warms up.
I thought about writing Joying about it but I expected the kind of response you got. Plus, I've had my unit for a few months already so a PayPal claim isn't an option. Please let us know if you hear anything else about it from Joying.
Hi Joshnat,
Yes we have the same problem. Sometimes I can get mine to light up by turning the headlights on and off a couple of times. Are you sure that you cant make a Paypal claim? As far as I know you have 180 days.
Anyway, you should write to them and let them know that you know that many others have this problem.
Regards
Kurt

You may have a faulty screen, my first one did something similar and wasn't very responsive to touches. I returned and my second unit was like night and day with how much better it looked and worked.
Has anyone got a factory backup camera to work? I have a 2015 Camry and right now I have the older Pumpkin rk3066 and the place that installed it hooked up the factory backup camera. I got my new Joying hu yesterday and am going to install tomorrow myself. I'm really hoping I can use my factory camera with this head unit also.

I have the same car and HU, my oem backup carmera works. I bought a harness on Amazon including backup camera, USB, and aux in.
https://www.amazon.com/gp/product/B01BM3QGCO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Quick tip:
You can adjust backup camera brightness, saturation and contrast by touching the screen while backup camera is on.
Is there a trick to putting in the sd cards? Mine won't click in so it won't mount.
Edit: Forget it i just had to get the edge of a screwdriver and push it in. Had me worried for a minute.

Within the zip there is a file with instructions - HOWTO.txt
How-To install:
1. You need a Windows PC that is connected to the same WiFi network as your HU.
2. Unzip the attached file somewhere to your disk.
3. Run CMD.exe as Administrator
4. Change directory to the folder that you unzipped.
5. Run the install.bat script with an IP address of your HU as a parameter:
C:\Users\<username>\Downloads\Joying_JY-UL135N2_SuperSU> install.bat 192.168.123.137
6. Wait until script finishes and reboot your Head Unit.
7. DONE!
You should now have the SuperSU application working.
Hi folks.
Firstly, please excuse me if this is not the correct forum for my query.
I recently purchased a used Ford Focus car, and it came with a stereo powered by WinCE 6.0. From what information i could gather, it seems to be a Chinese made car stereo. And i don't know who manufactured it.
Unfortunately, when i select SD card from the touch screen, the screen turns a green colour. If i am lucky, sometimes, the SD card plays my music. However, most of the time the screen is a green colour when i select the SD card. Everything else works fine, Radio, GPS, Bluetooth.
I have used three different SD cards and different music files, still the green screen appears when i select the SD card.
Anyway, I 'restored' the stereo through the settings, but this had no affect whatsoever. Also, i was prompted for a pin number to do a factory reset. The pin number i do not know. And i used a needle to reset through the pin hole.
Does anyone know where i can get firmware and how i can install it please?
Specification:
MCU/DVD/BT Ver: A4-USB131128 / 1014 / JQ_LM_505_2012_09_28_V01
System: Windows CE 6.0
App Ver: 20131205
Boot Ver: 014b0000
Flash size: 128M
OS Ver: A4-CZGB0-130823-01-CE6-V2.2.6
UUID: C7D0600C-DE3A-4113-5438-583042445F30
Any help would be greatly appreciated.
Thanks in advance.
have you tried using a different card? if it still happens, i am afraid you may have to change a new headunit.
as these chinese "OEM"s are of no branding, there is little to no support for any firmware issues.

Don't think i can afford a new Stereo at the moment.
Besides, everything else on it - GPS/BT/Radio/Camera works perfectly, it is just the SD not playing music (50% of the time).
Do you know what the Factory pin/password/code may be??
Thanks for your reply though!

hi guys,
i recently upgraded my mcu to the sound patched version. sound is much better, but now the dam head unit cold starts every time. when before it almost never did. any ideas? i have already, factory reset, wiped cache, loaded my old mcu settings(like recommended saving them before the mcu update.) but still the same..... i have tried 3 or 4 different MCU's all with the same result. i read there is an option in extra settings, but mine doesnt have any option there except "play music for usb/sd card on start" or something along those lines.
Any ideias? its really anoying, as backup camera only works 30-40 second after cold start....
ps: my first mcu was mtcd_gs_v2_23_1, its a px5 unit. running stock rom, android 6.0. xtrons for the bmw e90
any help greatly appreciated.

Hello folks. Today I bought a second hand Galaxy S9 (G960F) phone after I totally smashed my old one.
At first, when I ran the service test code (*#0*#) all sensors/the screen/inputs/outputs seemed to work fine. However, after a short time of leaving the place where I met the buyer, I discovered that the phone started restarting randomly.
The first impression, based on experience was that the device is water damaged. I looked at all corners and there is no sign of cracks or splits in the glass. Moreover, I examined the water damage indicator near the sim tray (galaxy s9's have one of those). The indicator was dry white.
I excluded the water damage from thinking temporarily.
So here comes the dilema: Could those glitches be from software? Either firmware or ROM? I tried updating the firmware and the samsung fails to download the latest firmware. The last firmware update is from August 2020.
I have the following information:
- One U.I 2.1
- Android 10
- Baseband version: G960FXXSBETG8
- Kernel version: 4.9.118-18847185 # 1 Mon Aug KST 2020
- Build number QP1A.190711.020.G960FXXSBETH1
- Knox 3.4.1 API level 30 TIMA 4.0.0
- Service provider SW ver.: SAOMC_SM-G960F_CKH_DRE_QQ_0009 / 2b282a7f23017ece (DRE/DRE/DRE)
Lastly,
- Android securit patch level - 1 August 2020
The phone seems to function well. It doesn't seem to be locked on the network which bloats the ROM (3 (Three/Drei) Germany/Austria?)
However, sometimes it just restarts with a open padlock showing on the screen.
I can make this work, I know it and I have the following options:
- If you guys can help me, I could debug the curent software/firmware and get it to shore
- Find out how to install official firmware/rom that is not spoiled (Note: I need all security features and no ROOT. I need to use bank applications etc)
- If these fail, tear the back plate open and change the mother board with my old phone's.
What do you think? Can I achieve something here?
Later edit:
I tried doing a recovery mode factory reset after a cache wipe. When I booted up again I was warned that "A unauthorized factory reset attempt was made".
On the other hand I ran a geekbench and I obtained normal scores without having the phone restarting on load so I think the assumption that the hardware works fine and the phone is still sealed shut is right (?).
Anyone with experience in this - flashing stock firmware?
Hi,
I have a PX30 head unit with Pumpkin branding.
I've updated the ROM to Hal9k which is great but the unit often fails to boot sitting on a black screen. Repeated attempts to reset the unit, and it eventually turns on.
Auto sleep is not working either so its always cold boot, even if the unit has only been turned off a few seconds.
I would like to try updating the MCU software but cannot find a file.
The version info is: MTCE_HT_V3.60_1, Aug 14 2020 10:19:07
I have tried to register for manufacturer forum to ask there but didn't get a response for account approval.
If there is a newer version that would be great, equally the same version or an older version that is known to be stable could also help me.
Thanks!
Looks like I managed to answer my own question, I found version 3.71 on a German forum, here is a link to it.
210.4 KB file on MEGA
mega.nz
Still don't have the sleep working, if I change it to delay shutdown or sleep it makes no difference and its a cold boot every time. I've checked my wiring and I'm sure the unit is still getting +12v from the car when ignition is switched off.
Anything else I can try or check?
Hello, try if you don't have Default power status - OFF: Factory settings/126/Other/Default power status - set ON or if the radio does not remember saved stations, then set: remember last state.

Hi, I tried this, the power settings don't make any difference.
If the unit is only off for less than say 1 hour, it will boot up again OK. It's not instant on like some youtube videos, maybe 10-20 seconds. I guess this is still standby mode?
If the vehicle is parked overnight, unit will not boot, just get a black screen. It takes several (usually 10+) attempts to reset it before it eventually boots.
This is really annoying, is there anything else I can check? The only thing I didn't change yet is the "customer type" number, would this make any difference?
Changing the customer version is not recommended, serious control errors and sometimes a black screen may occur, but it is up to you if you take that risk. Sometimes a new MCU update will make this change. The last number after the underscore indicates the customer version, MTCE_HT_V3.60_1, the last one is 1 so the customer version will be 1. If you have updated the MCU this may have changed. It is best if you have saved the factory settings in the dmcu.cfg file, with this file the MCU will be updated and all settings will be returned to the original settings. Factory settings - EXPORT button and save the dmcu.cfg file to external storage, if you do not specify a path, it is saved to the root directory by default. If the error was caused by the update to Hal9k, then the problem may be with this update, try to update again with wipe data or reinstall the original ROM. If that doesn't solve the problem, try a different car type in the canbus factory settings. Or the canbus adapter may be faulty.
Thank you, that is helpful. The unit was already doing this before any updates, I was hoping that updating the ROM and MCU would help but it seems to have made no difference.
I don't have a canbus adaptor.
