Witson Head units

This thread I started to get some help for custom roms for witson head units. This HU similar to MTCB with Configuration OS Android 4.4.4 system CPU Rockchip 3188(PX3) Cortex A9 Quad*coreRAM DDR3 1GBFlash Built in 16GB , But cannot be installe custom roms of malaysk .
I tried various ways to flash but has not worked yet. I am not a developer so would not able do much.
There is no way to enter recovery by buttons , I tried everything I could as per instruction from [ROM][RK3066/RK3188][SD/HD] Malaysk ROMs thread.
I tried these after getting latest factory firmware for back up.
1] extracted custom romes and replaced boot, system, oem and misc img files in stock firmware folder and flashed,
everything works but stuck at recovery. did clean wipe and install from storage but sd card does not show or failed to mount. please check pics.
2] when reboot at that stage , it starts without problem but no sound , what might be the problem? it reboots itself every 2 minutes!!
3] thought reinstall MCU but factory setting password does not work tried 126/ 3368 (stock rom code), is there any workaround.
I feel some problem may be due to mixing up stock firmware and custom firmware file( I don't understand as i am not a developer) . Attached stock firmware folder sceenshot, can anyone suggest how to manage these files.
Russian forum has a thread on these units but no much progress.
can anyone help me out to flash custom roms.
I attached couple of pics and firmware details with factory firmware link thanks to 4pda.

Yes, I do use the sdcard slot to update. for stock rom update, we need insert into sdcard slot( GPS Slot) then restart the unit. then it updates automatically till the end before reboots, it says to remove sdcard. once sdcard removed it reboots thats it. it never stops at recovery mode while factory firmware update.
I cannot use update.img file to update firmware.
I cannot enter recovery mode by pressing any buttons even I tried on pcb board, do you have any idea to overcome it?
yes i could root it with kingsroot.
I am looking for a custom rom like malaysk kind of to flash. I am waiting for someone who could help.

Try another rom friend maybe something wrong on that rom did you try malaysk rom for ur device ?

Hello, I have the same problem I cannot enter in recovery mode and install custom roms of malaysk .
I have a Witson W2-F9111T.
who could help me

there is no recovery implemented, no fastboot.. so I have no idea how to flash those

aren't the Witson head units the same as the RoadNavi S160? if so, then Kotix makes a ROM for them, check the S160 thread

Could you share the instructions you got from the seller?.
I'm also in the same lane, I cant seem to find any custom rom for my device, the good part though is that our hardware is way better
Now i have plenty of small issues, so I want to flash the original rom back.
Thanks !

Found this already on the russian website.
I think we CAN use malaysk rom if we use just the system image, and keep our uboot and MCU.
Will try this out and feedback here.

there "seems" to be a 5.1 release, however the build.prop shows 4.4.4 ?

Do you have firmware 5.1.1 from Witson?

I've updated my radio to 5.1.1. In my opinion nothing has changed, besides the information in the settings version of android 5.1.1
I think this is an old android only has written 5.1.1. The system looks the same as when you press the Application Manager can see the logo android 4.4 kitkat on the notification bar.

I think it's a hacked 4.4 to show 5.1
If you look in the build.prop of the download then it clearly shows a 4.4///
aaah... typical chinese cheating here, even on a firmware

Yes, i see build.prop earlier
As such a large company can just cheat customers.

Recovery is a blank screen, so is the os!

Hello,
I need some guidance. I flashed the latest version of malaysk ROM. Unfortunately both recovery and the rom give me a blank screen. I know the screen works because I see the malaysk logo when I attempt to go into recovery.
I am presuming I could use a PC and fastboit mode, but how is this fine on an android head unit.
I have a 1 din, flip screen type, KLD5, RK3188 model.
Please help me.

There seem to be a lot of units flashed with the latest rom that have lost the bootloader and recovery.. I'm not seeing any fixes for this. Has anyone fixed a unit that is now stuck at the bootloader with no recovery possible?
Sent from my SM-G928F using Tapatalk

I did not try it, but this might work:
Holding the power button while turning on the unit will get you into bootloader mode. **This is battery power not acc power** The screen will be black but plugging in a usb to the front usb will prompt the PC to install the RockChip bootloader drivers - this might help http://www.cnx-software.com/2013/11...install-rockchip-usb-drivers-in-windows-xp78/
(From http://forum.xda-developers.com/wiki/Hui_Fei_Type#Bootloader_mode)

I don’t have a power button on my HU, I wonder if the RST button or the smaller reset button above would work?

Corolla E120 with XRC7.1-0035 model K.O

Hello everyone ... I have the model XRC7.1-0035 for the toyota corolla e120 with android 7.1 MTCD_XRC_V2.54a_1 and for a failed update restarts normally but already in the main screen to the 5 seconds it goes away to restart and it does not give me time to enter the menu . I have tried all key combinations and I can not get into recovery mode. Someone who uses it can indicate how it could be done. Thanks for the help and sorry for the english but it is for google translate...

Which procedures have you followed?
Enviado desde mi D6603 mediante Tapatalk

Well in principle the radio worked well the only problem was that the calls by the hands free was heard very low, tell the seller and I recommend updating the DVD, he indicated a link to download the file new4_px3_7.1 (201700705) I put in the micro sd the 2 files then in the sd card slot and through the configuration menu update but something did not go well as the radio reaches the main menu but after 5 seconds it restarts. If I get to the recovery menu would be a solution but I do not get it in any way, is it possible that the drive does not have recovery installed?

All units have
When I asked you about procedures....I meant which procedures for getting into recovery have you tried to not retellings the same method you tried

For volume up the Bluetooth calls you only had to enter into factory settings and increase the volume for Bluetooth inside the "voice" tab
Enviado desde mi D6603 mediante Tapatalk

According to the seller you have to press the left button (tone) and press on reset, all this with the micro sd card in the gps slotthen, release the reset and hold the left button until the recovery menu comes out, but it did not work for me.

Turning up the volume in factory settings I did until the 20th that I think was the maximum and it did not work.

Search on xda under mtcd units the different ways for entering into recovery.
You can try the bootable sdcard method
Enviado desde mi D6603 mediante Tapatalk

Thanks for replying, I will try bootable sdcard method and comment if it works

I tried it and it bootable sdcard method step by step does not work for me, it stays black screen and it does not respond

If you have reset button (hole accessible by needle):
Press and hold until you see the button lights blinking
Release and press again...holding it until you see marshmallow logo....release and wait for recovery
If it didn't succeed use the same method but with your power knob button
Enviado desde mi D6603 mediante Tapatalk

I have searched the forum and tried several methods to enter into recovery with MTCD units but for the moment I have not tried one that works . The reset button I kept it pressed up to 30 seconds and nothing appears ,We will continue searching and testing. Thank you and if you know something new I would appreciate it if you let me know

One video...
https://yadi.sk/i/gfJILxx93LHejF

Other procedure I seen before on other units:
*1. turn off a radio power
*2. Press "reset" button all time
*3. Turn on radio power, after 1-2 sec, release "reset" button immediately, then click reset button quickly again shortly, then wait*
4. after 0.5-1 min, you will see page the update
Enviado desde mi D6603 mediante Tapatalk
If you can't power off your unit....I suggest you to extract the radio from dash to ensure your radio is not connected (acc off and batt off)

Well there is no way, I tried all the combinations and I do not get the recovery menu to appear. The seller of aliexpress every time gives me a different solution that does not work which leads me to think that he only sells them but that he has no idea of ​​the operation of the unit. I do not know what to try...

Other procedures....
If you have no success with the reset button
Connect a usb keyboard
Press right ALT and PrintScreen
Start pressing repeatedly on E (not holding E pressed, but press...release... press... release..... rapidly)
The boot logo shows and after a few seconds the unit reboots itself
Release right CTRL & PrintScreen and continue to repeatedly press on E.
You should be onThe Recovery
Or.. you can remove the unit and short the cable labeled( KEY1 ) to ground then reboot.
Enviado desde mi D6603 mediante Tapatalk

Finally I was able to restore the unit, disconnecting it from the electricity several times and pressing the reset button for a while appeared the menu recovery, which capricious is android to times. But the problem with the volume of the calls continues. Is it possible to install version 5 of android being in 7.1?

Android 7.1.x Recovery.img file for Allwinner T3 P3 Quad Core Headunit

Hello,
I upgrade my T3 P3 Quad Core Headunit to Android 7.1.1 using the rom given at:
4pda.ru
/forum/index.php?showtopic=837879
(With the help of Google translate)
I missed upgrading the recovery in the process because of which I cannot run the system upgrade now.
I would be grateful if someone who has upgraded their T3 P3 Quad Core headunit to Android 7.1.1 could post a copy of their Recovery.img file (can be obtained using the terminal of and application such as Rashr).
Thanks.

1. You are mistaken. Recovery does not perform the update function.
2. If you had Android 6 and you upgraded to Android 7, then now you need to use the method of emergency firmware update.
3. What firmware do you want to install?

Thank you for the response.
I installed version V8.3.2_20180105.162617_AKW1-mod and would now like to upgrade to V8.3.2_20180119.100305_TW2-ZHC-mod.
Both of these are Android 7.1.x. When I run "system update" the processing icon shows for 1-2 minutes and then android reboots. However, after boot up the rom version still shows the same 20180105.
If I boot into recovery the version shown is android 6.0.1. Was assuming that the system update isn't working because the recovery was not updated.
Would appreciate your guidance on how to upgrade the Android 7 version & if the recovery update will help or not.
Thanks.

You need to rename the firmware files, as you did the first time.
Use these methods of emergency firmware update.
1. Hold Home (mechanical button), press Reset, and keep holding Home until the update starts.
Instead of the Home button, you can connect the KEY1 (Steering wheel controls) wire to the ground. Or press the button on the steering wheel connected to KEY1.
2. Yet another procedure might be needed for some units: Using a USB stick prepared as above and inserted in the unit, turn ignition to ACC, press Reset, turn ignition off, then after 5 seconds turn it again to ACC.

Hello,
Sorry for using this topic but I'm a new user...
I have an Android 7.1 radio that doesn't work correctly after disconnecting the canbus box from it.
I did a video https://youtu.be/PcQrKQD8FKs
Can you help with is?

Hi Intrusion4,
I know it's an old post but I'm having the same problem on a Allwinner T3 P3.
At first the Bluetooth stopped working 6 months ago but that didn't bothered me too much, instead this morning i found the GPS icon blinking and everything not related to the Android OS stopped working (Radio, Music Player, Navigation, Car Info, etc). I can't raise the volume and brightness either just like you in your video.
Do you still remember if you solved it and how did you do it?
Thank you

Select system update in settings or try Malaysk MOD App which forces the device to boot into the recovery, but actually the update should be detected from the android system itself
