Huifei RK3188 lost Bootloader - Android Head-Units

Hi everyone,
I just bought one head unit Huifei RK3188 for Audi A4 with canbus, and after intalled the last rom from Malaysk I made something wrong because now I can´t see the bootloader, or go to recovery mode. Tried to install recovery from TWRP and CWM and nothing hapends.
Tried to reinstall a fresh "update.img" from rockchip tool batch 1.7 and it says " download IDB failed".
Tried to search for the NAND to make maskmode but I don't know what is the chip.
Can anybody help me?
Many thanks

Same here. It came with the latest Malaysk ROM.
Could it be that Malay forgot to include the bootloader?

Can anybody, who updated to the latest Malaysk ROM, confirm that the bootloader is still there? I just would like to know if we did something wrong or if the bootloader is really missing in this ROM. Thanks!

Up.

Ill check if you tell me what I'm looking for.

Same here, after update black screen. No logos at all, like there is no bootloader. I can't even get into recovery with the mathod that was working previously.

Still the same, the unit works but with some problems like no recovery, bootloader, when press eject of dvd the screen goes to black, when using the BT call the screen goes to black, reverse camera too....

Hi !
I was just about to install the latest Malaysk ROM "update_4_4_4_FUSE_1024X600_RK3188_16_MAL_17_03_2016" and now I see this post. Is there a risk for me to have the same problem as you guys with this one ?
When you guys say "the latest ROM", I see it's in January - the one I downloaded is from March 17th. Can anyone confirm this has been fixed and I'm not risking to loose bootloader and recovery access ?

Nevermind. I installed it - no issue to report.

My headunit has lost recovery after malaysk ROM
Hello, I have the same problem. Recovery is a blank screen, the os us also a black screen. Everything working fine then flashed malaysk rom. Interested to hear what I can do.

OK.... I've bricked my unit - totally my fault. I had MCU version MTCD and Malaysk roms are for MTCB.
I tried hundreds of resurrection methods and nothing worked for me. Now waiting for support from seller...

Same deal here.. Bricked the unit. No fix as yet.

Did someone manage to fix the black screen? Maybe via adb?

I had exactly the same problem. Tried to install an update.img using Rockchip Factory Toolkit v1.39 and got the same " download IDB failed" However, I tried a different usb port on my pc and it worked !! I suggest you persevere and try differnet ports/ different cables because it can be fixed.....

Latest Rom for joying 10.1 Need to root with rom

Having a hard time finding the latest or best Update.img for joying 10.1 head unit
Its still rk3188
Ive followed some links but the update. Img i tried failed I need link to the best latest rom for the 10.1 model Not sure if screen size is relevant for type of rom
Can someone please link me ?
Also should i out the .img on the nand flash or usb drive
What latest ROM? The official? Look on joying site.
Also, there are two different versions of 10.1. Both have different ROM requirements.
Is there a reason you need a new rom? That's a pretty recent product.

Yes there's a lot of necessary tweaks changes that make the unit desire able.
Mine is the 5.1.1 there is no rom for it
And I also just bricked it cause someone linked me to a 4.4.4 model rom..
Now I don't know how to try restore it
Cant get into recovery mode at all now

Sorry to hear you might have bricked it. Yes, at the moment there doesn't appear to be any community ROM available for these units. You may have seen other other threads on the same topic.
You will most definitely want to contact Joying support about any possibility of unbricking.

FLASHING THE WRONG ROM WILL BRICK YOUR DEVICE AND VOID YOUR WARRANTY WITH JOYING!!!
If you have a 4.4.4 (MTCB) Head unit you can get the latest Joying ROM on carjoying website or you can use Malaysk ROM.
If you have the Lollipop Android 5 (MTCD) Head unit you need to contact your seller for the ROM and MCU.
I have had few head units already which do not even go into recovery because of wrong ROM/MCU was flashed.
There is no Malaysk ROM for android 5 MTCD Head unit now.
You can donate to support his work so we can send him a MTCD head unit to work on and develop Android 5 ROM

So they are saying you need to change components to flash nougat?
They are full of s**t. If that was true then i would not be able to flash marshmallow back which i downloaded in the past from their webpage.
Very true . Just not sure why it won't boot as says it has flashed successfully.
I saw some posts that 7.1 works with the new burning tool v2.42. havent tried it yet though.
That would be interesting to find out . Didn't know there was a new tool .

Android Head Unit Identification MCU ZHAN(NOR)

Hello,
i buyed a Taffio S200 Android Radio for my Opel Astra J with an Octa Core PX5 2GB Ram and 32Gb
Can anyone tell me how i come into the Recovery Mode? The Radio havn't any Buttons, only a small Reset Button. I tryed it with Terminal Emulator but it's rebooting i see a little bit like Recovery Menu but than it's rebooting again to Android.
I search a Custom Rom too, but i only read about MTCD and MTCE but my device shows MCU version: 2018-04-16 17:04:06 ZHAN_(NOR)_90_C9RD6686_CAN(A)PX5D1804160.
I couldn't find anything about this mcu.
Have anyone an idea how to root this device? I can't try a lot of things, because i can't restore a brick without Recovery Menu and stockrom.
Does your HU have a USB port? If so, plug in a USB keyboard, reboot/reset the device and try pressing Alt + Print Screen while tapping i or e (both works)

Have you tried enabling adb over Wifi on the device using https://hvdwolf.github.io/Joying-RootAssistant/ (or even rooting ~ some risk is there, so try the adb method first) and using an adb command to reboot to recovery?

The Joying Root Assistant didn't work for you to root the device?
Some firmwares lock you out of the recovery menu, where it can be only used for updating your firmware. Maybe that's why?

Your unit is a WINCA/ROADNAV manufactured S200 and it can be rooted. I know because I have exactly the same MCU firmware and probably the same Android build. Check out the rooting thread on the first page of this forum. In there is all the info you need.

I could but my stock ROM will most likely not work properly on your unit. Each ROM differs slightly from car to car with the WINCA units. It's daft but it's how they chose to design.

Please send me the link to where you purchased your unit as well as all you know about the manufacturer.
Mine too is ZHAN_(NOR) i bought it in Polish Reseller, original seller is bluepowercn.com, the name of the unit is GREATSO S200. Cannot find in Russian Forums and XDA any information about that ROM or UPDATES/MODS. Alie Store:
Bluepower Electronics co., ltd
youtube.com/watch?v=AEvCX2bomoA - info from Witson with same MCU, Ok Found mine it`s: W2-W279
Is it possible to upgarade or install mod rom to W2-W279? I have some issues with OBD2 connection via Bluetooth and Bluetotoh contacts storage plus minor bugs... cannot find on XDA if ZHAN_(NOR) is possible to upgrade or change of the stock rom.
DennisBa unit is W2-W072 - Opel Astra J - i think its the same brand and topic is consistent.

Hi, my car is a Opel Astra J, too and I need to reflash the MCU. I flashed the wrong one... Can you share your MCU maybe? Thank you!
Or maybe someone could share this firmware to me like in the pictures? After flashing wrong MCU and newer system version, my Canbus Box and car won't be detected anymore.
I need this firmware with ZHAN(NOR) MCU (for Opel Astra J).

[Help] Upgrading firmware from Android 6.0 on 8227L unit

Hi
I just bought this radio 1GB/16GB:
https://pt.aliexpress.com/item/Silv...167.html?spm=a2g0s.9042311.0.0.2742b90apiEUzI
I'm new on the Android Car radio. I already intalled the unit all is functioning well. But mine came with the version 6.0 of android. The seller already sent me a lot of firmwares to flash but or they didnt run or the one it worked kept the radio on 6.0 version. (8227L UI06-firmware_v14_20190219.zip) - I uncompressed the two files for the root f the external sd.
Anyone have a firmware for this model? I can send the name the firmware that seller sent me that worked but kept the model on 6.
FOr updating the seller told me to make a reset and put five fingers on the screen.
By the way I was waiting for the update to see if the function will appear but this firmware doesnt have a favorite contacts widget so it's easy to call contacts. I tried some alternatives from google play but when dialingit said i cant find the phone app. Anyone knows an alternative to solve this situation.
Thanks in adavance and I'm familiar with android but this is my first car radio.
Is there any post regarding this model? I didnt understand yet if they are OEM with different layouts or if its a need for the seller release an update...
I see that this forum is not very active like other xda ....It's my first time with a car radio and there isn't one person who can help...
search thread for 8227l firmware or youtube ighostsgunnaz. i believe i have android 9 file that is for touch only. i needed file for touch and key press (volume knob). am uploading zip fiiles to file share host now hope u see and it helps.

Firmware update(8227l_demo)

Finally after searching I found firmware for this head unit(YT9216B) with less bugs .
Youtube Link:
Note: This update is for 1gb/16gb device and if flashed on 2gb/16 or 32gb might give errors.
Firmware link: https://drive.google.com/file/d/1CfdRfnzywmeR88inwqhxUXEXmAX8zt7x/view?usp=sharing
I bought a car with what appears to be the exact same unit, but the Android version is newer. Is it any point to upgrade?
Here's what mine says:
Android: YT9216B_00002_V004_20190906 (only the date differs from video)
Android os: 9.1 XY AUTO: 3.1 (8227L).
The firmware in the video aparantly has a lower Android os version? But the other is newer? I'm a bit confused. Will this be a downgrade for me?
check in cpu-z if its android 8.1 or 9.1 so i can provide you the latest firmware

Hi Rahul,
I have checked images and as requested here is the latest firmware.
if update is not detected format usb drive with Fat32 format and then just copy firmware zip file and paste in root directory of pendrive. For assistance do check the video. If still the android upgrade button is disabled then try another usb port.
Also try factory reset and then update the device.
Update at your own risk.

Hi Dear, Im not able to install this your provided image on my car head unit. I tried system restart/reset button even tried five fingers for boot options. But no luck. Can you please help. Thanks in advance.
If you really want to improve your YT9216B head unit - this is all you need - ever
There is little point in doing factory updates as they normally improve nothing.

When devicxe starts to boot try tapping with finger at middle screen until you see a message in upper left corner , then system updates automatically. It will says DETECTED or something like that. USB drive or SD card containing upgrade must be in port when DETECTED !
