Hi is there anyone on these forums that can repair one of these chinese units
I have one of these https://www.ebay.co.uk/itm/384770479698 in my 2006 Merc. its a MTK8667 Android 11 based unit. FF_866X is the device name, i'm sorry I do not know the MCU
I was sent some update files from the seller https://we.tl/t-UeDC40i6Ul XRC-8667 升级软件 Q腾实UI多合一-国外-1280x720_v32_20220223
during the update process it copied the superimage ok but then something came up in red but it came up to a kind of recovery and said erasing... it then rebooted it gets to the car logo screen, before android screen then goes to a blank screen with the following in bottom left corner...FASTBOOT MODE and wont go any further
I have pressed RST then two fingers on screen until i get "detected" but all i get is the same fastboot mode again,
I have redownloaded and extracted the firmware and reformatted my usb drive to fat32 and tried the whole process again and tried in both usb slots but no sucess.
I have obtained other mtk8667 firmware files 8667.bin and 8667.upd from this topic https://forum.xda-developers.com/t/firmware-junsun-v1-8667q-8g-128g-vhd-qled.4405475/ on this forum but I have tried many different ones and it just wont read the usb, still just goes straight to fastboot mode....is anyone able to help me I have messaged the seller but no reply
So far I have tried about 7 or 8 different firmware versions, the sellers own, some junsun versions, ossuret versions even xtrons versions(all in correct format of 8667.bin and 8667.upd on root of usb formatted to fat32 but it does not read the usb.
The usb slots are still working as I can plug my phone in and it charges but the unit does not seem to have a full recovery mode
I have tried using a program called adb and fastboot on the computer but will not connect to the head unit
I have manually installed MTK drivers to the computer and tries a program called magic thunder but again would not connect to the unit.
I have tried to find a memory dump online but nothing, all I can find for mtk8667 is firmware consisting of 2 files 8667.bin and 8667.upd
I have now removed the unit from the car so i tried removing everything but 1 usb slot and removing the power for 10 mins before powering up and attempting to flash again
So i think i'm in need of expert help, so i'm looking for a repair shop, or person that can take the unit and hopefully get it working, more than happy to pay a fair fee and to post it to you, or if you are within a couple of hours travel from Yorkshire(Leeds area) I will happily come to you

Hey guys
My car head unit is from royal for hyundai elantra and it's stuck on the starting Android logo and can't get past it so can you please help me fix it? Thank you
No one has any idea on how to fix it?

It is probably in a boot loop. What did you install or do to get it in that boot loop?
If you didn't do anything, you might try to rest the unit or disconnect if from 12V and wait at least 2 hours.
And edit your first post to change the title. I assume it is "resetting" and not "resting"

1- no I didn't do anything to it. It was working perfectly and I had to switch the car off and then turned it on the boot loop issue started.
2- how do I disconnect it from 12v? Sorry but I am have zero experience when it comes to cars.
3- and you are right it's resetting but I have no idea how to edit the title of thread.

2- Get it out of the dashboard and disconnect the harness or the power plug or take the fuse out.
3- like I said. Edit the first post. It will also make the title editable.
Do you have a small reset hole in the front of your unit? If so, try to reset it with a "pointy" thing like a needle or something else.
Try what surfer63 says, because he has way more experience than most of the people about Android Head Units on this board. If all else fails try what I did after having a bootlooping HU for nearly 4 months :S
Had the same issue. The HU (with 2 USB ports) was some unknown brand called Funrover loosely based on Joying firmware. What worked for me was
- Download the suitable Joying firmware : joyingauto.com/blog/post/joying-intel-sofia-android-car-stereo-software-update
- Extract it on the PC and then copy the firmware files on to a freshly (FAT32) formatted USB drive
- Plug in the USB drive to your HU USB port (1?)
- Since your HU is already bootlooping, plug in a keyboard and use the following key combination> Alt + Print Scr + tapping i (or e, both worked for me) to get in to recover
- Ideally the recovery option will detect the plugged in USB and start reflashing the firmware so that you will be able to use the HU again.
Hello!
I've recently got a Silverstrong Android 9 Head Unit: https://www.aliexpress.com/item/32822937592.html?spm=a2g0s.9042311.0.0.328e4c4dWZb7Fi
Can someone help me on how to get adb access or a custom recovery (mainly for rooting purpose)?
I have to mention that I've tried connecting a notebook with adb via and USB cable (male USB type A to USB type A), but it seems nothing happens. I can tell that the unit's USB ports are working for USB sticks.
I have also tried some combination implying the reset hole present on the front, but I couldn't make it work.
Any help is appreciated! Thanks!
Edit: I have to mention that the unit packs a MediaTek MT8321M if it matters.
Just an update: I have followed the instructions provided here for rooting: https://forum.xda-developers.com/showpost.php?p=76725981&postcount=740 . Everything went well until I tried to reboot the device. Now it is stuck in a bootloop (it passes the kernel bootlogo but it is stuck on Android bootlogo) and I really need to access its recovery. It would be my only hope to try to unbrick it. Unfortunately the only physical switch of the unit is just a reset hole on the front which will cut the power right away (tried multiple pressing combinations, none worked). I really need to enter recovery mode and I am pretty desperate, so any advice is welcome. Thanks!
I couldn't make it boot into recovery mode, but it did boot when I placed on a usb stick a file named "ZQ_MTK1B_UPDATE_HeXinDa_EN_8003_08152051.zip" and then it started to flash it automatically. After the flash completed, the unit recovered from bootloop, but now it seems there is no sound and no radio. I posted all of this just in case somebody ever will have to deal with same kind of trouble. It seems the unit is actually branded as alps ZQ8003 and I will ask the seller for some firmware/more technical info.
Hi, I have the same problem. Did you make it?
I just bought a Belsee Tesla style Android head unit with PX6 (double din, 1980*1080, 4G, 32G)
After installation for about 1 h, and I changed the boot logo to a new high resolution one. Then it did not work, stop at boot logo
The seller has send me a px6_format zip file and let me put it into a disk, plug the disk and restart the unit to recovery. But this method did not work. The unit kept at logo with no reaction.
I also tried many other method to try to enter recovery mod, but no luck.
Who can help me with this? Happy to pay for it! Thanks

Did you try use a pin to reset the unit?
Also, where did you plug in the USB with the new update PX6 zip?
Try to put it in the USB slot on the unit, not the two from the connection cords.

I've tried every method, but no luck.
I removed the core board, and post it to the seller for an exchange. Then it works again. But the radio now cannot find any channel.
Terrible head unit, strongly suggest every one do not buy this type of trash.
Hi all, a need help. After an unsuccessful update, I received a bootloop. There are no physical buttons on the device. Found instructions for recovery through ANDROID TOOL. I connected it to the computer in maskrom mode, but I can’t find the firmware that needs to be uploaded in order for the device to work. Share a dump that suits me or give instructions on how I can restore the device.
They're all there in the MTCD forums.
Thanks for the answer, but all I found is different ota update.zip. And my device is loaded only in maskrom mode.
That's why I'm looking for a full recovery version.
Hi, you have to use the IMG file that contains the recovery and then update normally via OTA. For example, the IMG is:
CHS2_RK3399_10.0_IMG(20200424)
HCT7_rk3399_10.0_IMG(20200415)
OLS_rk3399_10.0_IMG(20201012)

I downloaded the firmware, I start to flash it and every time it breaks off by 50-60%. I used different firmware from the attached ones and different versions of AndroidTool. And different driver versions. Log attached.

Erase first
I did, first cleared, reboot and firmware. The result is the same I read a lot of documentation, they wrote that there may not be enough power, but the power supply is 5A.
I noticed that the device turns itself off after a couple of minutes of operation. Possible overheating! I will check it.

I had the same problem I bricked my headunit (rk3399 PX6 Android 10) trying to recover root after updating magisk to 25.1 went into maskrom mode but device lost connection to my PC and flash fails at different percentage.
Cause ended up being the adapter i was using to power the device I used 12v 2A adapter
After switching to 12v 10A adapter it finished flashing. BUT make sure the chip has cooling like a heatsink or it will overheat during flash.
I changed the power supply to 10A. Installed cooling. The result is the same. The device reboots even if nothing is done.
Have you tested another USB cable? @s.danyliak
I have tried two different cables. But I connect via usb which is from the device kit and also the usb a - usb a cable is possible in this problem. There are also only 4 contacts, and for otg you need 5. I did not find information on the board I attached the photo.
Does anyone have any ideas ?
Ask seller for schematic and share here for feedback
So I was able to achieve some result and broke everything even worse. In maskrom mode, I flashed boot. And was able to see the device as fastboot. But my joy did not last long. After rash actions, I flashed the wrong boot and now I can’t enter maskrom as I did before by closing the contacts on the keyboard. Approximately as in the photo below. The question is, how can I force him to enter maskrom mode?

Hey there,
If the update completes really quick, maybe it's because it isn't going properly.
Try various other usb sticks.
Normally you should have the time to read every steps during the update "writing partition blabla1, writing partition blabla2 ..." aso asf.
I had to try a dozen usb sticks before finding one that worked for me.
May be worth the try.
Godspeed
