[GUIDE] Android 6 SUPERMOD for YT9213AJ, YT9216B, YT9217B, YT9218CH - root, Viper4Android, TWRP, custom UI, brick recovery and more

[aadamuss]

Witam posiadam prawdopodobnie radio yt2913aj. Nie sprawdzałem tego wcześniej, a kilka dni temu przerwało się podczas ładowania Androida. Zresetowanie i leczenie z nienaprawianiem tego. Zdecydowałem się na sflashowanie, ale nie zrobiłem tego za kulisami. Kilka wersji, które istnieją, nie zaczyna flashować, a następnie znajduję zrootowaną wersję z tego forum i działa. Trwa to pomyślnie, ale kiedy wkładam radio do samochodu, nic się nie dzieje. Próbuję sflashować go jeszcze raz w domu, ale trzy też nic się nie dzieje. Myślę, że zamuruję. Czy jest szansa na naprawę tego z powrotem?

What kind of material is that where the TDA7850 comes in?

Hello propably i have radio yt2913aj. I don't check version before and few days ago is freeze at android loading. Reset and take out from battery don't fix it. I decided to flash it but find few versions what don't starting with this radio. Next i find one rooted and it start, it's show sucessfull. When i put radio to car nothing happen. I take it back to home and try flash it one more time but at home nothing happen too. I think i brick this radio, is any chance to repair it back?

We can repair it for you if you wish to send it to the United Kingdom. Alternatively, find a similar repair shop near you

The UI is so painful. My immediate goal is to run Android Auto so I can plug in my phone and do what I know. My later goals are custom everything. So I need a root and image that plays well with this unit. Can someone help me on my journey?

good morning friends attached photo of my board of my radio yt9213aj board model t9260 v1.2 but I notice that it is not the same board that they posted here to update the dsp chip. If you have the schematic and the location of the components for this board, I would appreciate it. Thank you so much.

You should invest into an Android Auto unit, if this is your main area of use. A full-on Android will do everything AA does, including all phone functionality. Our ExtremeMOD head units are deliberately blocked form using Android Auto and CarPlay

Your mod sounds like what I need then. Is there an issue if mine reads T9812B and not YT9812B?

What it 'reads', doesn't always correlate to what's inside, it's a general direction. Here is an example of one of the ExtremeMOD Android head units built from an XYAUTO YT92:



You have to look at the motherboard itself.

In any case, if you don't skip the backup procedure then worse case, if the mod doesn't work - simply restore your backup.

Your motherboard should have these microchips as the bare minimum:

.....

And look very similar to this motherboard in terms of layout:





Good luck!

My recovery at step 2 has failed for the second time.
I'm not totally hurt about $130 down the drain, so I was wondering what unit you would recommend? I dont mind spending a little to find something that's flexible and smooth.

Hello ExtremeMOD.
I have the model from the picture without physical buttons. Everything works fine for me except the microphone, because the person I'm talking to can't hear me very well and the FM radio doesn't receive the stations very well. Will I improve with this if I install and can this work on my model? Thanks a lot.

Unfortunately it will not, but you can improve the radio and mic audio in the Factory Settings (pw: 8888). You can find a lot of info here on XDA on how to do that.

This is my device inside and I believe it doesn't have a radio chip. I looked at your pictures from the beginning of the post and in yours I see that there is a chip in this place, but not on my device. I don't think I can fix the signal for FM, because I tried with the FM amplifier and I didn't get a better signal. I don't think I can help him Thank you very much for your reply and for the very helpful post.

Yes, your model does not have the NXP chip which delivers HD Radio. But it can be installed.

Is the one I could install the same as yours from picture above? Should I search by number from yours?
I can't clearly read the letters on the radio chip from your picture. May I ask if you have a clearer picture of the chip somewhere?
Thx.

Here is the product link. As well as the datasheet. Bear in mind that you need to add all the surrounding components (resistors etc) for it to work
