[Android Head-Units] ExtremeMOD:
I would advise against using this mod on your unit as it does not support "HIFI" models. I am currently working on an Android 8 super mod and that includes everything. Stay tuned.
[Android Head-Units] ExtremeMOD:
The new guide for Android 8 units is now available. It covers all Android 10 and 11 fakes.
[Android Head-Units] madsurfer1:
Can my unit follow this guide or should I follow another One?View attachment 5389371
[Android Head-Units] ExtremeMOD:
I would probably recommend the Android 8 software package instead.
[Android Head-Units] madsurfer1:
thank you so much for your anwser

I only want root so I can enable multi-window, is it an easier to get root?

Thank you
[Android Head-Units] ExtremeMOD:
The proper root for this unit requires modified firmware. You can of course try without it but chances are you'll either brick your unit or in "best" case get unstable root.
[Android Head-Units] ExtremeMOD:
First of all, really sorry to hear you had such an unfortunate experience.

Now let me add a few points to your feedback.

1. You need an understanding of both PC computers and Android devices to attempt this. Would you try to repair your car with zero knowledge or experience?

It's also a good practice to look through all the steps and tutorials before deciding whether this is something you wish to attempt.

2. The reason I create these guides is to give the users one-stop software solution in one thread. I couldn't find similar guides here.

3. Software packages are cleaned from the bugs and issues you would normally experience in these units and overall improvements are considerable. If you check the video in my signature, tell me - does this seem like a slow unit? And it's only 1Gb RAM one.

4. These software packages perform even better with appropriate hardware mods. Especially the sound quality. You can check out this website for more info.

5. Users who experience issues post here. But this package alone has over 300 downloads. This indicates high success ratio.

I also help individual users by PM.

Thanks again for your feedback
[Android Head-Units] sylcat:
Well, let's go point for point a little bit.

1.) Yeah but when was that in question unless you're mayyybe trying to sass a bit? 😆 My personal experience is plenty for this, enough to multimeter my harness pin by pin, design a custom wire harness with 3d printed parts, run debugs with my obd, reconnect lane cams, write my own android apps if I feel like and on and on. My point is to warn to readers that these instructions are pretty deceptive about how involved it is skillwise and just needs a simplification redo. My problems might have been isolated hardware failure, I still don't know after tons of debugging.

2.) Cool, noble, etc etc, you're very nice for doing it. I just want people here to write clearer I guess. Sorry I landed on your project to express it. Years of XDA and it's so much life lost to information gaps / gotcha tutorials. That gets pointed out and it's usually ego mania. Take some crit, XDA posters could really learn what a tutorial format that communicates to most everyone should look like instead of assuming their skill at that is also great thus providing good intented tuts that cause uh....pain.

3.) It'd be fun to test myself but it doesn't work. Looks functional sure. Speedy compared to current gen anything after esp hacks? Nawwww. If you're cool with it chugging after one or two background process I get it. Waze eats enough. While it won't be everyone, if you use a screen with more expectation I again advise against this hardware.

4.) Again for people considering this, how much extra hardware and wiring do you want to buy and staple to a piece of crap and shove behind the head unit to make it almost not suck? How many 3rd party peripherals do you want back there doing one job? Are the manhours you'll spend trying to reign this unpolishable turd in monetarily marginally close to worth it? Appreciative to the hack effort if you're stuck with this screen. If you haven't bought it friggen doooon't.

5.) I argue since silence is not success confirmation it could just as easily indicate people downloading it, the process failing, them not wanting to continue with a newly recognized tragedy of a device, and possibly just dying of dysentary right there while reading the instructions which are in 8 different folders 👍
[Android Head-Units] ExtremeMOD:
1. Why not explain what were the issues you encountered?

2. It has taken me a couple of years to learn how to properly work with these units. I tried my best to write as easy to follow guide as I can. I'm grateful for feedback as it helps me improve these guides. They are continously revised. I'm not paid to do this and it is a fairly time consuming undertaking.

3. Current gen Androids are an unfair competition to hacked and re-hacked Android 6 or 8. On the other hand, you can't do much with anything above API 27. Forget about rooting, Viper and TWRP. Also be prepared to pay hundreds of dollars for these units. People who buy Mediatek head units, normally can't spend such money but still deserve great results. This is why I share these mods packages. And it's completely free. All it takes is time and patience.

4. People here and on similar forums are many times interested in making improvements without spending loads of cash and might already have some basic equipment and skills. I haven't posted any hardware mods guides yet but I'm going to.

There are no 3rd party peripherals required. Most of the spare parts can be found in old computers. We at Extrememod.co.uk use premium spare parts as we sell these units fully modified (for charity, no profits) but it's not a requirement.

5. All I can do is to encourage users to post here so I can help if needed.

Cheers

I spent a few days as I said fighting it after it all fell down during the USB unsigned driver portion of the project. Across 3 pcs, driver reinstalls, pin verifications, living in device manager, 12 tech forums tabs open and everything else under the sun the software just refuses to communicate with the screen in any way.

I don't remember everything, I'll get you verbose logs if I ever touch this project again but don't hold your breath. I'm surely bitter over wasted time but in general the nature of in car entertainment cheapouts that need these hacks to even start limping have caused me to reevaluate life itself and what not to waste it on so I'm just pulling the trigger on a Model 3 finally. Screen problem solved for me I guess 😅

My suggestion for readers considering buying remains to run far away if you're not already stuck with the hardware. But if you are and you have infinite patience trying to buff it up then I guess keep harassing poor iceblue here until your hack works and weeew I do wish you all luck!
[Android Head-Units] ExtremeMOD:
If you are unable to restore your unit, I can have a look at it if you can post me the motherboard. I live in UK. If that's not an option, why not donate it rather than throwing it in the bin? I can arrange pickup if it's within reasonable postage fees.
[Android Head-Units] sylcat:
I'd donate but the math will never work out. It's installed in the honda which I'm selling already, so it'd take pulling it out which us my time+shipping hassle from the states. If I pull it out it's easily worth the $250 cost of the unit in therapy to see it *explode* and I'm not joking so I doubt you're gonna front that too. :v I mean also I don't really want anything about these boards perpetuated. If the next buyer doesn't want it in there it's getting smashed. These kinds of posts I make again to save people time on caaaancerous base products.
[Android Head-Units] ExtremeMOD:
I understand. I actually care about people succeeding with these mods. You can clearly see how much time I'm putting into these guides and helping people with any issues that come up.

I even offer repairing boards, for free. Donation is a last resort if someone wants to throw their head unit into the bin.

Any modification, as it's essentially a hack - means you're taking a risk. But with proper backup, the risk of ruining your head unit is minimal, as you can always restore it back to what it was.

Again, I'm sorry it didn't work out for you but the issue isn't with the software nor the guides as the success rates are overwhelmingly high, judging from the feedback I receive here and on my website.

[Android Head-Units] lizama.academia:
Hello! I would like to know if this is okay for my unit or should I try another. Attached photos.

please if you can help me, thank you very much
[Android Head-Units] sraboudi:
Hello,

i tried to upgrade my head unit without to do a Backup before.

The Upgrade has failed and now i have only a black screen only the led panel light do function.

Could you please help me to unbrick him and revive him again

Thank you very much upfront.
[Android Head-Units] ExtremeMOD:
Normally I just change to full on black wallpaper so that it blends in when you switch between apps.

With the Car Launcher, you won't see the wallpaper at all other than when switching between the apps.
[Android Head-Units] gurgelrga:

obs sorry for the english
[Android Head-Units] ExtremeMOD:
Sorry to hear that. Please share pictures of:

1. System Info

2. Kernel version

3. Motherboard front and back
[Android Head-Units] gurgelrga:
Here Sorry for delay
[Android Head-Units] ExtremeMOD:
Sorry but even though the unit says YT9216BJ, the hardware setup is not compatible with this software package.
[Android Head-Units] gurgelrga:
Do think any other mod of your work in this unit ?
[Android Head-Units] ExtremeMOD:
None of my mods will work on your unit without alteration, I'm afraid.
[Android Head-Units] gurgelrga:
O have problem is to connect to PC the unit I can't make backup I follow the guides but still unable to connect
[Android Head-Units] biohazark:
Is it possible to update android 6 YT9216B to this android 8 version ??
[Android Head-Units] ExtremeMOD:
As I said, none of the mods will work on your unit. It has some alterations compared to standard YT9216BJ head units.
[Android Head-Units] ExtremeMOD:
Possible? Yes. But I wouldn't recommend it unless you really know what you're doing. This will require a specific Android 8 bootloader file unique to your head unit.

Frankly, Android 6 is better by far, when it comes to my mods for compatible YT921xx devices.

Also bear in mind that YT9216BJ package is not compatible with YT9216B head units. Please visit my super mod thread for your particular model. Check my signature.
[Android Head-Units] TboneL:
I cannot get my TPMS sensors to work with my yt9216bj AHU. I downloaded a BLE app and it never locates a device. Same app works on my android phone. Is there a setting or a driver that I need to install? I'm running android 9.1 car edition, kernel 3.18.79, API 28. All other bluetooth devices will connect (phone, ELM327).
[Android Head-Units] ExtremeMOD:
Wrong thread I'm afraid. I only provide support on my mods.
[Android Head-Units] TboneL:
Sorry, I'll repost in another thread. I watched your video and it is the best instructional video I have found on XDA. I bought a spare AHU because it went down to $89 on Amazon. I will follow your instructions and try it on my spare before the one in my car. Keep up the good work!!!
[Android Head-Units] ExtremeMOD:
Thank you. Hope it works out well.
[Android Head-Units] BigMoneyHustlin:
i have same unit. had same problem. u need to start sp flash with radio on then hold RST button, plug in usb cable, then release button. screen will stay black and pc will read unit. when done hold RST button again to restart unit. i didnt read this post first so i bricked mine twice but was able to flash my backup and save unit
[Android Head-Units] Alboooz:
Hi mod Iceblue1980, i got a head unit for my bmw320d e46 no hard buttons, the XY AUTO, YT9216BJ and android 9.1 on it. My concern about my head unit is few to mention, the wi-fi areal is very low, hardly connect to wireless router at about 3-4.mtr, or direct wi-fi appears but not functional, and i face lag's on maps and music player a bit, so i am willing to downgrade to this android room v.6.1 if you recommend me that, and if you think this will solve my wi-fi troubles.

I tried to locate a hardware wi-fi external antenna pins but no success, so if you have any idea, would you show me on pic please.😊

Btw, i have some knowledge on flashing rom's on samy android phones.
[Android Head-Units] ExtremeMOD:
Look at this example - is this what you're after?
[Android Head-Units] Alboooz:
Yeah, the head unit is the same with this one on video link, and i already downloaded the rum and tools, i just have to find USB cable to plug in, but my question. is, will it have better wi-fi performance and longer signal area connection or not?
[Android Head-Units] ExtremeMOD:
To improve Wifi (and subsequently BlueTooth), a hardware modification is required. You need to install a WIFI antenna. I plan to record a video guide on this mod soon.
[Android Head-Units] Alboooz:
Please, it would be great, i already have open head unit few times to find out where is the external antenna pin print so i can connect external antenna wire that i have from other broken Laptops, but no lucky.

The Bluetooth works fine.
[Android Head-Units] ExtremeMOD:
There are a number of different ways to do it but we prefer our way which generates much more stable operations. Follow us on YouTube to get notified when new content comes out.
[Android Head-Units] gurgelrga:
You successfully install this room or the other ? Work fine ?
[Android Head-Units] RandCat:
Does SP flash tool not work with a head unit with a front USB port? I don't have the 4 or 6 pin USB connector and it doesn't seem to work with the front port. I may have a dead USB-A to A cable, but I want to confirm.
[Android Head-Units] RandCat:
Is there a way to verify the MediaTek driver is installed post removing the device? I tried another comment's suggestion with holding the reset button (in my case it's a pin hole) and plugging it in during that, but it just restarts and doesn't download on SP Flash Tool.
[Android Head-Units] ExtremeMOD:
SP Flash Tool will work with any MediaTek device. However far from all MediaTek devices have compatible, out-of-the-box USB ports. If you don't have the ports shown, this thread is not for you.

Yes, if you watch this video on installing the drivers and get exactly the same outcome, then you're fine.
[Android Head-Units] RandCat:
I found out the USB A to A cable I got is probably dead. I connected an adapter to it and couldn't even get power to my phone. New one ordered.

Unrelated to that, today I did a virus scan on my computer and it detected the file android-terminal-emulator-1-0-70.apk. A VirusTotal scan brings up more results. Can you explain this?

https://www.virustotal.com/gui/file...c934e016ed6023e93e4f4efeeff1d36811b?nocache=1
[Android Head-Units] RandCat:
New cable arrived, confirmed it transfers data by hooking it up to my phone. I press start on SP Flash Tool, plug in the USB, and nothing happens. I tried the reset thing too. I also installed the driver twice to make sure I did it correctly. Any advice? This is the correct thread I'm sure, my head unit is YT9216BJ (8227L-DEMO).
[Android Head-Units] ExtremeMOD:
That's a false positive. Here's the virus threat report done today on the same file:

Please share pictures of your head unit that show:

Hello, nice work.

I already have installed "Rooted TWRP firmware 20190523 HiFi" so my device has TWRP. Can i flash this firmware through TWRP app?
[Android Head-Units] ExtremeMOD:
At your own risk. I strongly suggest you follow the installation process as it stands.
[Android Head-Units] ExtremeMOD:
Thank you. You should not attempt installing this software package unless you are intentionally trying to rollback to Android 6 API 23.

You have Android 8 API 27 currently. You will find the link to the appropriate mod in thr first post and my signature.

Are you looking to rollback to Android 6?
[Android Head-Units] RandCat:
How do you know it's Android 8 API 27? I'm just looking to get better control over the system.
[Android Head-Units] ExtremeMOD:
We work a lot with these head units so we can tell a lot from the pictures you shared. If you look at our signature, you'll find a lot of resources on these types of head units and you can always visit our website to learn more.

Our software packages will certainly help you do that. Just make sure to install the correct one and follow the instructions. If you don't, you will end up with a bricked device.

Here's the thread for Android 8 for YT9216BJ 2/32 GB.

A side note - this package will not work on your head unit as it is made for YT9216BJ 1/16 GB.

So, here is few pics and version of my head unit, still not rooted, i did fix the Wi-Fi signal as its shown on one of this pics jack pin out nr.10 but internet connection still slow and direct Wi-fi i can't get to work even i establish connection between head unit and the phone.

As for the USB wires is the same trouble, the phone connects to the head unit to charge the phone battery, the pop-up request on the phone for data transfer i accepted but i don't see the devices on Myfiles app, so if my USB is not fully functional, i'm afraid i'm confused to root my head unit device in this conditions for now.

[Android Head-Units] ExtremeMOD:
First off, this isn't the right thread for you as you have Android 8 API 27.

What you're trying to do, requires modified firmware and root at the very least.

The WiFi speed issues can only be solved with a hardware modification.
[Android Head-Units] Alboooz:
How that, it says it's Android 9.1, is that kind of a fake or what!

If so, which rom is suitable for my head unit, or isn't any of them, bcz. I already downloaded this version in hope i would be able to install on my head unit?
[Android Head-Units] ExtremeMOD:
It is fake indeed. You should try this instead.
[Android Head-Units] Alboooz:
Thank you very much for advising me, so i have lot to read on that topic before i can make move.🙂
[Android Head-Units] ExtremeMOD:
A lot of information is provided in the first thread. Also when you follow the guides as you install everything, you'll learn a lot more. Happy upgrading!
[Android Head-Units] android@100%:
That's really a helpful guide for beginners. I am facing a problem. drivers are installed correctly and the HU also connects and shows up in the device manager but SP flash tool is unable to get/read anything from the HU, I don't know what I'm missing here. plz help me out i really want to update my HU. tried with 2 different PC both running win 10..

EDIT: Found the solution. Now going to try the update.
[Android Head-Units] android@100%:
Waiting for an update. or u can just share the pic of the pinout. Thanks for your efforts dear
[Android Head-Units] Alboooz:
I haven't updated jet my head unit, because i'm confused a bit with technical issues i'm heaving with my head unit.

I fixed USB female cabe and Wi-fi as long as i have at home connected to 12.V +- adapter, it's snappier and i can connect to my USB phone and data transfer all though i don't see any connection possible on my win10 tabletPC, but i don't complain for this it's because i haven't install drivers jet on my tabletPC.

The technical issue is...when i place head unit on my car and connet to it, the android OS is quite lagging, the wi-fi capacity data transfer is about 25% when i check at this site www.teestmyspeed.com the internet speed, BoatBrowser takes about 5.sec to launch, and google maps very lagging up to 20.sec, that reminds me lagging old and forgotten Amiga 500 game computer graphics. Music and movies work fine, BT phone is okay, so i have to find out firstly what is bothering my head unit when is connected in my car that it slows down.
[Android Head-Units] ExtremeMOD:
You need a laptop or desktop PC. Tablet won't work.

As for the issues you mentioned, they have to do with both software and hardware.

This software package will not make your wifi faster unless you install a proper wifi antenna.

The package will make your head unit faster if you follow the speed hack guides. But if you really want to improve it, modifying the hardware is necessary
[Android Head-Units] Alboooz:
Thanks for your quick answer to my complaints.😀

I have one laptop with win7 and one other tabletpc with winXpsp3, but then question is, what kind of USB cable i have to use, is it pc2pc cable or what, the tabletPC with windows10home got tiny Usb mobile jack like the galaxy note4 kind of, the other laptop and win10home got standard USB.v2.0, i mean the win10home tablet is olso like laptop with it's keyboard extension.

As for wi-fi antenna, i have add wi-fi antenna from one laptop, using pin 10-wi-fi outlet and pin 9.gnd, on this pics i uploaded weeks go, it just, when i have at home connected to 12v adapter seems to work better, but when i connect to car cables it slows down, and the cables i never modified anything at all.
[Android Head-Units] matsam9800:
Hello mate,

Please can you confirm that I am in the right place for my Head-Units.

Actually, I would like to update it to SUPER MOD but I am afraid to lose it, Please can you support me with this update.
[Android Head-Units] ExtremeMOD:
Yes this package is the correct one. You don't need to worry about ruining your head unit if you follow the instructions.

If it doesn't work then you can always restore your backup.

You currently have Android 6 installed (fake Android 10.1).

If the package doesn't work, after restoring your device, you can try the Android 8 mod. Link is in my signature.
[Android Head-Units] matsam9800:
Thanks a lot for your reply,

Actually, I am from Syria and you know the situation, the problem is it is very difficult to take of the head unit from the car and connected to power suppler, So can i do it in car with full connecting to the car battery?
