Hey, i followed the guide because technical support from XYAuto sent me file what not matched my firmware.

This original firmware is a desaster. Now i tried to install this sexy project on my yt9216cj..... I did backup like in the guide. Then i deleted all data like in guide....but now i cant do aything. With Sp tool no download and no upload. Everytime i get an error message with: S_FT_ENABLE_DRAM_FAILED (4032)

The hint says:

Please check your load matches to your target witch is to be downloaded....

WHat does it mean. Now the radio will not start. Very strange
[Android Head-Units] ExtremeMOD:
This software package is not compatible with your head unit. You need to follow my other guides, either Android 6 guide or Android 8. Both can be found in the OP or my signature.

Restore your backup and try again.

DRAM failures and solutions are also described in my SP Flash Tool guide.

I've to buy a new unit for my step-dad car. Can you send me those sellers links?
[Android Head-Units] ExtremeMOD:
If you need to buy a whole head unit and not just the motherboard, you can do so on AliExpress. Just make sure to ask the seller to share the system info screen with you before buying.

The system screen info should start with: YT921...... and of course avoid YT9213A and YT9213AJ series

You can PM me and I'd be happy to guide you.
[Android Head-Units] shiner88:
I've tried again:

used scatter and preload from the old modified firmware(the same i've used to restore my unit after brick) and the ROM_USER from your package. This is the error i've got (also tried 0x0 as begin address):
[Android Head-Units] ExtremeMOD:
You need to use the scatter file and preloader from the package you downloaded. If you mix and match, this is the error you get.

If you can't flash the ROM_USER file with those files provided in the zip file, it means your head unit is not compatible with its current setup.

The software package should definitely not magically activate "HIFI". It's a sign that something's wrong.

Unfortunately, I can't help you as your head unit requires a much more complex flashing procedure.
[Android Head-Units] shiner88:
Yeah, I understand. No problem, thanks anyway for the help
[Android Head-Units] cheesmountain:
Hallo, ich versuche auch, das Gerät zu flashen. Nur komme ich im SPFLASHTOOL nicht weiter. Windows erkennt das Gerät nicht. Muss der Strom vorhanden sein?
[Android Head-Units] ExtremeMOD:
Please share pictures your System Info and Kernel.

Please follow the guides. All the information is there including electricity.
[Android Head-Units] ExtremeMOD:
You have a YT9213AJ head unit without the audio processor, running Android 8 API27.

This package isn't for you, I'm afraid.
[Android Head-Units] cheesmountain:
Wenn ich das Radio und den PC mit USB verbinde passiert nichts.
[Android Head-Units] cheesmountain:
That's a shame, is there a solution?
[Android Head-Units] ExtremeMOD:
I'm sure there is but not for this package as you would need to modify your hardware to make it work.
[Android Head-Units] cheesmountain:
Thank you for the information.

20 Sep 2021 - UPDATE​

A new tutorial video is published on how to recover your Android Head Unit from brick by Test Point Recovery method.
[Android Head-Units] calin978:
Hello.

I just installed this firmware and another 10+ firmwares ,and still i have this problem .

My orignal resolution was 1280x720 and now is 1024x600.

Navigation is 8" 2din with 2 button knob.

In second image is the original firmware
[Android Head-Units] ExtremeMOD:
In the guide, on the very first page, it is clearly stated that this software package only supports 1024x600 resolution.
[Android Head-Units] calin978:
Now i understand...

Exist any solutions to resolve this navigation back to 1280x720 if i don't have any backup?
[Android Head-Units] ExtremeMOD:
Again, read the guide on the very first page:
[Android Head-Units] waz000000:
need rom for: i did make a backup but the scatter file wont work so i get an error on flash tool
[Android Head-Units] ExtremeMOD:
Your head unit is not compatible with this software package. Your scatter will not work. You need to extract the scatter file using WwR MTK and same goes for your preloader file. Then restore your backup.
[Android Head-Units] waz000000:
black screen now, still connects to USB but thats all :(
[Android Head-Units] ExtremeMOD:
I'm sorry but did you not read any of the guides, looked at any of the pictures, and just decided that this would be a simple update? Your head unit is not compatible with anything in this thread. You have bricked it.

Hi,

Does this mod/launcher include volume adjustment linked to car's speed?

Has anyone figured out how to do it with these units?

I had it working on my previous PX5 unit (which died), but I think the software was specific to hardware.

Thanks

[Android Head-Units] CruzeRSLT:
I have same issue but my volume doesn't get loud until 20. My EQ doesn't work in mine either. Hopefully there is a fix but I do not know how to do anything but download the updates. I'm a noob at anything Programming Related.
[Android Head-Units] ExtremeMOD:
I hear you man. And trust me, this is where my journey began. Then I kinda got into it and now it's a part-time hobby of mine.

Frankly, there isn't much you can do unless you know what you are doing. Truth to be told, these units are cheap for a reason, however with some intermediate software and hardware modding skills you can make such a unit perform on par with the expensive ones ($ XXX / XXXX), especially the sound quality and it will only cost you a few dollars in materials. You will need to address things like software (especially Viper), built-in audio amp and passive cooling as well as improving WiFi speed and mic quality.

I actually buy these chinese units (many times bricked or broken), mod them and sell them (for around £70 - £150 depending on the unit and work done) on eBay and give any profit to charity. But really, anyone can learn this stuff. And if you don't want to, then best to buy a branded unit like Alpine, Sony or Kenwood
[Android Head-Units] CruzeRSLT:
Thx for reply. I'm swapping out the awful tda7388 amp chip and upgrading to a better drop in chip. My speeds are actually pretty good. I'm learning as I want to install viper. That's what's most intimidating thing for me. I'm still unsure how to properly do it yet. I'm willing to learn though. That's awesome what you do.
[Android Head-Units] ravindraaec1@gmail.com:
Brother , is it crooct ? "rom user file 14.4 GB". And no twrp file find in above download link.
[Android Head-Units] ExtremeMOD:
Definitely not, however this is a memory dump (once installed, you will still have like 14Gb of free space). Install it fully and you will have everything in there ready to go.
[Android Head-Units] EvilEVO3D:
Hello friends, I have 9.1 android fake aida64 says 8.1 api27, I have the volume issue at 19 and 20 where it pauses and loudness is activated immediately. It is really bugging me, I tried freezing the settings app so that I can use a different equalizer still it did not work. I used Ice box to freeze apps without rooting the device as I have no idea how to do it and I am afraid to brick it. As it was a pain in the a** to install it in my car, how does this memory dump work? Is it safe and is it ok me going back to 6.0 android?
[Android Head-Units] ExtremeMOD:
It doesn't matter what Android version you currently have as long as your hardware supports the Android version you are trying to install.

Personally I wouldn't recommend taking the risk of performing memory dump import or any other modifications if you aren't prepared to take the head unit out of the car.

You can easily power it with 3 jumper cables connected to a 12V/5A laptop power supply (AC/DC adapter) so you don't need to take the ISO harness out.

Trust me, you will want to do this by your desk, not the car. If you brick the unit, you will need to open it up to revive it with the Test Point method.
[Android Head-Units] EvilEVO3D:
Well this is not for me then, lol. It is fitted in a VW MK5 and they are very hard to remove it takes me about 40 mins and something always breaks in the plastics surrounding the unit. I could try the upgrade method with one of the latest firmwares released on xyauto website. It's not like I am looking to make it faster or have more options, I just want that damn volume bug gone, it is driving me insane. And sound quality is perfect cause I have an amp and a subwoofer installed. But you go from 19 to 20 and all hell breaks loose. And I saw your firmware on youtube, you have outdone the Chinese, their firmwares suck and what you have is just beautiful. Congrats to you
[Android Head-Units] ExtremeMOD:
Appreciate that mate. Thanks.

If you are using external amplifier then you are good. Just make sure to put noise filters on the power cables and magnet noise isolator clips on the RCA cables to avoid any background noise. You can find them cheap on both Amazon and eBay.
[Android Head-Units] Freddie1337:
Is there any possibility that one could get a better description, How to do? Maybe a video? Is new with androids hack. Is very experienced with Iphone jailbreak. :)
[Android Head-Units] ExtremeMOD:
There are already a number of step-by-step guides on this forum, you just need to search for them and follow the instructions. To make it easier for you, you can search for these topics (search parameters in bold):

1. How to make full backup of 8227L (or any YT92xx model really, you can also search for making backup of Mediatek unit)

2. How to import memory dump of 8227L (or any YT92xx model really, you can also search for making backup of Mediatek unit)

3a. If you brick the unit, search for: How to unbrick 8227L (or any YT92xx model really, you can also search for making backup of Mediatek unit)

3b. If "3a" doesn't work, search for: How to unbrick 8227L via Test Point (or any YT92xx model really, you can also search for making backup of Mediatek unit)

The way I made this file is that you don't need to know anything about jailbreaking, only how to backup your unit (in case something goes wrong) and how to import a full memory dump via FlashTool. Make sure that your MCU and Android version is same or very similar but your unit has to be:

YT9213AJ / 1Gb RAM / 16Gb FLASH

Good luck!
[Android Head-Units] reganEZ:
Hello,

I would like to ask for some help if possible. I dont have the tools or the know how to open this unit and since i bought this from a reseller i am pretty sure i have no warranty.

You seem to know your way around with these unit so I would be ever grateful if you can take some time to answer my questions.

I have a android unit that i dont know the make of. Its specs are

YT9216B_00002_V004_20190728

Android 8.1GO

XY auto 3.0(8227L)

can bus 3.0

DDR 2G Flash 16G

CPU A7 1.3ghz*4

display 1024*600

MCU 3.1

Any help here upgrading my unit? i found this on the internet would this be correct?

http://file.xygala.com/?dir=uploads/XY公版/9216/9216B/Android9.1/外文/横屏/1024x600/UI1_v6.5

also, if i dont want to root, can i just install this from SD? or can i root from SD without taking the head unit?

Thank you for your time
[Android Head-Units] ExtremeMOD:
To be completely frank, there's really no point in risking bricking the unit with upgrades such as you mentioned. It will not make it better in any way.

The reason I mod these units is to make them considerably better in performance spending very little money. The latest project I completed outperformed a £500 branded head unit in speed but most of all in sound quality, according to the buyer. And I bought it for just £25 on eBay. This is just an example. And about half a year ago I knew nothing about modding.

You can either try to do some research and make improvements that will make a difference, stick with what you got or buy a branded unit such as Kenwood, Sony or Alpine.
[Android Head-Units] reganEZ:
we are under lockdown due to covid as well and thought tinkering would be a good idea/fun. just wanted to have a safety net( someone with technical know how before doing it).

thank you for your time. best wishes
[Android Head-Units] ExtremeMOD:
Your safety net is the low price you paid. In addition, just make sure you got these things done before starting the "tinkering":

1. Ensure the Mediatek drivers are properly installed on your computer

2. Don't do mods in the car. You can easily connect your head unit to a laptop AC/DC adapter (12v 5A)

3. Do a full memory dump (backup) of your unit and then import it back just to make sure it works.

After these steps you should be fairly safe to go. Good luck!
[Android Head-Units] reganEZ:
actually, I paid 30000 NRs ( about 253 USD) for my unit. things related to cars are really expensive here in my country.

Thank you for your helpful suggestions.

regards
[Android Head-Units] ExtremeMOD:
Oh wow that is very expensive indeed! Best not to risk it then. Here in UK these units go for under $100

Hello, I do not understand, you have to connect the car radio to the pc to flash your firmware or simply start with a usb key to install your firmware?

Impossible flash, this is the error following the tutorial
[Android Head-Units] ExtremeMOD:
Try to use my video guide instead. It's in the first thread and in my signature.

If that doesn't work, it's a driver issue. Follow my guide on how to install Mediatek drivers and make sure to use the drivers I attached.

Let me know how it goes.
[Android Head-Units] ExtremeMOD:
The symptoms are described in detail in my SP Flash Tool guide. I am releasing a full video guide, probably tomorrow, on how to successfully backup and upgrade your head unit.
[Android Head-Units] biker_boys:
Update another wrong rom and remove the preloader and I think the error is because of that but I can't install it.
[Android Head-Units] lince_0011:
Thanks for your answer. In fact I have used your video for the test point and my laptop detects the device without problem, just like flash tool. The problem is basically that I don't have a backup to fix the problem, and I'm trying to fix it by searching here on xda.
[Android Head-Units] ExtremeMOD:
Okay, please try this package:

YT9213AJ Bootloader Restoration (Android 6)​

Remember to install the full firmware package after you have restored your bootloader.

If it doesn't work, describe in detail what you do and what errors you get and we'll troubleshoot further.
[Android Head-Units] biker_boys:
I think I need the preloader file for MT8127 but there is no preloader file in the folder. Tried putting in supermod yt9216 file and flash file but it remains black. Is the preloader always the same or does it change?
[Android Head-Units] lince_0011:
Ok I'll try.

The guide to use would be this?

Full Restore with SP Flash Tool - MediaTek Android Head Unit.pdf

drive.google.com

Or should I just use the scatter file?
[Android Head-Units] ExtremeMOD:
First you need to recover your head unit. Then simply "Download" the firmware in SP Flash Tool, ticking all the boxes aside from preloader.
[Android Head-Units] lince_0011:
I have performed the procedure using test point:

first to recover the bootloader I have installed the scatter file just marking preloader in the format option.

second I have installed the boot1 in advanced mode following your video.

The above steps were done without any errors.

Third, I have installed the firmware by checking all the options in download mode without any error, the result was a black screen.

Did I do something wrong?
[Android Head-Units] SykoraLukas:
Anyone updated to 7.0?

what´s new?
[Android Head-Units] ExtremeMOD:
Here's the video I just uploaded. It should help.
[Android Head-Units] ExtremeMOD:
When installing the firmware, the Preloader box should not be ticked. Especially if you successfully uploaded BOOT1.

Also, it can take the head unit up to 15 min to boot the first time.

Have you done the full format of your flash by the way? I.e deleting everything including the bootloader, like shown in the video?
[Android Head-Units] ExtremeMOD:
These units run on Android 6 or Android 8.
[Android Head-Units] lince_0011:
I have repeated the process again from the beginning, this time when installing the firmware I have not marked the preloader option.

I have connected the unit and it is on a black screen, according to your indication I will leave it connected for a while, waiting and it works.

About your question, I have followed your video to carry out the whole process.

edit: only the lights turn on but not the screen.
[Android Head-Units] SykoraLukas:
I mean version of XYAUTO, not Android.
[Android Head-Units] ExtremeMOD:
Then you're in the wrong thread. This is a thread for non-factory firmware so anything from XYAUTO is moot, as the so called "upgrades" from the manufacturer do absolutely nothing.
[Android Head-Units] ExtremeMOD:
Okay, try this. You do not need to remove the preloader for now, so don't use Format ALL.

"Format All Except Bootloader" in SP Flash Tool

Download and install (via SP Flash Tool) the latest (Android 6 API 23) factory firmware for YT9213AJ - link - it's fake Android 8.1 (same way you did before, i.e preloader unticked)

If step 2 still gives you the black screen after restart, repeat step-2 again, only this time

include

preloader tick box

If none of the above works, format everything again including bootloader and we'll continue the troubleshooting only this time we'll be uploading Android 8 API 27.
[Android Head-Units] SykoraLukas:
And is carplay there in your rom?
[Android Head-Units] ExtremeMOD:
No it's not. Or rather, whatever potential Carplay capabilities are there from stock, would still be there but I haven't touched it as such.

[Android Head-Units] ExtremeMOD:
I'm sorry but there's no more help I can provide. If the information in the video tutorials doesn't solve the problem, and you followed them and did exactly what was advised, then your head unit is broken beyond recovery.

All I can advise you is to try again.

If you decide to throw away your head unit, please consider to donate it to any of the mod developers here for testing and development.
[Android Head-Units] biker_boys:
When I made the copy of the rom, I accidentally deleted it and now I have no backup copy. And since my radio is a 9212b with audio chip it is a bit strange. Any of the 3 roms load me well but the black screen does not change, the version that is on the official page does not work for me ...
[Android Head-Units] ExtremeMOD:
If your head unit is 9212B, you can't use any of my mods.

If you don't have a backup, you will need expert skills to restore your head unit.
[Android Head-Units] lince_0011:
The result is the same.

Annex step that I have done:

1- In flash tool, format select format whole flash except bootloader.

2- I have installed the scatter file of the original firmware without checking preloader.

When I reboot I still get a black screen.

3- I did step 2 again including the preloader option, the result is the same black screen.
[Android Head-Units] lince_0011:
Do you think there is any way to revive it?

I don't know what else I can do.
[Android Head-Units] ExtremeMOD:
I can only assume that last option didn't work out for you either? Okay, please send me a PM and we'll try souple of more things.

Actually that "guy" is me, or rather it's a group of guys doing a charity project. Yes, SuperMOD packages are put together by us and we use them in the units that we build and we share them for free here and on other forums and also provide free support (to a point). You do not need to have an ExtremeMOD head unit to install these software mods however, as long as your head unit is compatible.
