I used https://xdaforums.com/android-auto/android-head-units/everything-yt9216b-t4007063 to flash my unit as I needed root to fix the bloody radio.

The seller was never replying to my messages so I gave up getting any software from him.

My unit is NOT this one, it's a 9" generic (Carlaoer) 8227L one (YT9216C).

I have to test your suggestion regarding TWRP screen timeout as this is EXACTLY the problem I'm having with mine...it craps out after a while. Didn't time it, but now 1 min sounds about right.

So happy to be able to talk to someone who has actually gone through all this pain :laugh:

As you can see most folks here are just either fishing for software thinking that newer is better or have never looked at flashing and are asking for a guide - which you and others have provided.

Oh...from the document you linked, the guy is using SP_Flash_Tool_v5.1352.01 and says <<does not work with blocks larger than 4GB>>

I used v5.1924 - maybe they lifted that limitation (FAT32).

---------- Post added at 18:32 ---------- Previous post was at 17:36 ----------

One last thing: you mentioned <<Note: TWRP crashes the UI if the screen times out for 1 minute, so go to settings and disable screen timeout.>>

I thought that would solve my TWRP backup but it didn't :(

It goes to around 500MB and crashes in a weird way: screen flickers like an old CRT TV that loses H sync - horizontal lines and bit blurry. I was counting on TWRP backup rather than system dump, as even starting the unsigned drivers is a problem on a Win10 machine that will NOT run in safe mode unless I put in the 56 BitLocker key...what a pain.
[Android Head-Units] chaveiro:
It crashes writing or reading and in what partitions?

Its nice to have more people interested here also., the Russian foruns apart from being in Russian, have too much information, missing links and threads with 1000+ pages. Really difficult to get anywere fast, but useful anyway.

Now i'm on getting the best user experience, do you recommend any Launcher in particular?

BTW: Just updated Root with Magisk instructions (much more clean and stable).
[Android Head-Units] Ipse_Tase:
It crashed after 500-600MB of WRITING the boot partition...USB stick or Internal flah, makes no diff. I REALLY hate SPFlash tools and would have preferred TWRP backup and restore.

BTW: I tried your suggestion to RST and touch the screen with 5 fingers...it did NOT bring me into TWRP. Still don't know how to get there other than from Terminal (reboot recovery) or Magisk Manager.

I use AGAMA for my launcher as after I changed the color it matched perfectly my red interior dashboard and info screen colors...looks like factory (to me :) )

Try Viper4Android for everything audio EXCEPT radio...it does make a difference. Got it with the ROM I flashed (see last post for the XDA link), but you can install it from Magisk Manager.

8227L-8.bin Upgrade

Hello,

I have tried to update my unit with 8227L-8 files, however nothing happens.

I have tried both USB sockets, unplugged the power for a long time, rebooted through Terminal and pushed the reset button for 20 seconds.

I have also tried your instructions to the letter.

I can see the files in the File Explorer.

I have also tried to format the USB stick with SD Card Formatter.

Tried atleast 4 different versions of the 8227L-8 files.

My unit is not rooted.

Anything else I can do to make it work?
[Android Head-Units] bicer79:
Takip
[Android Head-Units] zaborrilla:
Tray tapping the center of the screen continuously and intermittently after pressing reset button, if not works try the same but with the finger constantly in the screen (one long taping). The screen should say "detected" or something similar and the upgrade procedure should start.

I tried to put in 8227L-8.bin as download agent in SP Flash Tool but I get an error message.

Also I don't have a scatter file for it, just the 8227L-8.upg file.

I have googled SP Flash Tool along with 8227L-8.bin but can't find any relevant information. [MENTION=846158]zaborrilla[/MENTION]

Tried the various tapping and holding techniques but no luck. =/

---------- Post added at 12:43 AM ---------- Previous post was at 12:10 AM ----------

Okay, I think I'm starting to get it.

So in SP Flash Tool:

Download Agent needs to be MTK All in One

Scatterloading file, I use the one from the link I thought you meant.

However, 8227L-8.bin and 8227L-8.upg needs to be in the same folder as the Scatterfile, correct?

So I get these files:

Preloader

LK

ARM2

BOOTIMG

SEC_RO

LOGO

METAZONE

TEE1

TEE2

ANDROID

CACHE

USRDATA

I have selected all except for Preloader, should I uncheck anything else?

Thanks a lot, there is HOPE!

[Android Head-Units] grvdggr:
So I tried the new method in the description but it didn't work.

My unit won't recognise the tapping, so that method is out.

When I connected the unit USB male to PC USB male, nothing happened.

Might be the USB cable so I have soldered it.

Question: Should the unit be able to show in the PC when turned off?
[Android Head-Units] zaborrilla:
I read somewhere, at least for my unit, that the usb Drive used for updating should be connected to the usb cable that has 4 wires( in my unit, one cable has 6 wires).

[Android Head-Units] Ipse_Tase:
You will NOT get any notification from PC when connected.

The scatter file IS included in the software I linked to if this is what you want to flash. Methinks however that we're talking different units here. The topic was for the VW unit, the software nomenclature looks nothing like mine. So make sure you are looking at software for YOUR unit.

Use the 4 pin USB connector, remove power, and test doing a readback : only when you start the process plug in the USB cross cable and you will see the PC detecting the unit (red bar at the bottom, changing colors of read is successful).

Worst-case scenario, you might need to look for thev2 test points to short, but I only needed that because I screwed up the preloader one time...never needed after restoring it.
[Android Head-Units] zaborrilla:
Just updated my unit. All went OK. I post pictures of before versión, after version, different launcher after install, cpu-z (how can I see if is really android 10?), etc...

[Android Head-Units] Ipse_Tase:
Both work on mine (Carlaoer as well) with the sw in the link. Again, just the name does not mean much, it's generic branding. You need to make sure it's the same CPU (probably) and MCU (uncertain) before flashing anything. Do NOT jump. Read some more, look at the requirements on 4pda.ru and decide if that IS your unit.

It was 100% match for miine, so I proceeded with the flash - and still fked up. Have a Plan B to recover (I suggest ensuring first and foremost the SPFlashTools works for you and you grab a system dump).

BTW, I hope you know you need "Headunit Reloaded" to make AA work...find the forum for it.
[Android Head-Units] zaborrilla:
You were right
[Android Head-Units] grvdggr:
But still, that's Android 8.1 you got. =)

I have heard it's less demanding than 10 and our units are on the weaker side.

---------- Post added at 08:38 PM ---------- Previous post was at 08:31 PM ----------

So I got some errors in SP Flash while trying to root the device.

I followed a guide on how to get rid of those errors and formatted the flash drive except the bootloader.

I ended up with a dead unit.

Won't respond to anything except to light up the buttons when I turn on my headlights.

USB can't connect, no response.

I guess I can try to connect power and then try SP Flash again.

If that doesn't work I think I need to shortcircuit the points. [MENTION=4522071]Ipse_Tase[/MENTION] Did you just put a wire between the points?
[Android Head-Units] Ipse_Tase:
Mine ONLY works when the unit has NO power (I removed the black power connector in the back before anything)...start SPFT and an operation, ONLY THEN connect the USB cross cable.

When I fked my preloader I had to short the test pins WHILE connecting the USB cable....so that might be what you need to do.

Regular "Download" where you select parts of the image works without the short, writing to flash from the dump does not. At least in my case.

I can't search now, but I posted a few days ago the picture of the pins on the board.
[Android Head-Units] bicer79:
I added my MCU number in the picture. I have installed root rom on phones, I have information. But there is no tape main software, fear to be brick

Google Translated
[Android Head-Units] Ipse_Tase:
This is why I recommended going to the thread I got my sw from and following the steps very carefully. This is not as simple as flashing a ROM or a kernel from recovery.

IF you manage to get recovery (the link I provided has that in it) iy might get easier after...but know that you cannot invoke recovery as you would on a phone...so SPFlashTools is a must.

Good luck, there is not much else I can add.

I'll link it again...and

guys, this is totally derailing the thread which is about a completely different unit. So please be mindful of that.

Do I need to cross over the USB data + and -?

And does it matter if the scatter file is not correct for the memory test?
[Android Head-Units] grvdggr:
No, don't cross over the cables.

Scatter file, don't know.
[Android Head-Units] chaveiro:
If memory read is working you have everything needed to unbrick.

Load correct scatter file, select at least preloader, original boot, a recovery (twrp if you prefer) and all the small partitions you had originally to be able to boot and get into recovery.

Press download then short the jumper and connect the usb cable.

Depending on model may need to power externaly also by the same time you plug usb to have enought power for the cpu to run.

I wonder how many people are buying these headunits based on the FALSE claim that they run Android 10. lol Not just this brand, but to my knowledge, ANY brand. As far as I'm aware, there are NO Android 10 based headunits. The home button icons, settings themes, and kernel numbers give it away. 95% of the time it's Android 8.1.0. Not even 9.0.

Originally I had a YT9213AJ, however since I managed to brick it I couldn't get it back.

Now I'm on this firmware: Full YT9213A_ui2_8227L_20200417_Flash_no_data

Works perfect.

But when I have flashed Android 8 it stops at the boot screen.

The files I flash over the YT9213A firmware is just ANDROID, 8227L-8.bin doesn't have any other files in it other than USRDATA.

Atleast that's what SP Flash Tool tells me when I manually locate each file and tell it it's 8227L-8.bin, error message "Please check the load image file is correct or not?"

Here is an example when I have tried to point to 8227L-8.bin from BOOTIMG.

So my question is, how do I make it work?

Do I need another bootloader? Is that the reason upgrading from a USB stick doesn't work?

Ele amigo. Esse problema da rádio FM tem solução?

[/ CITAR]

Com a antena de GPS que já estava instalada no carro o fm, o som e os comandos de volante, tudo parava. Quando instalei o aparelho no carro, já tinha uma antena de GPS instalada - o cabo era bem mais longo. Quando eu desligava o conector da antena de GPS e afastava o cabo para longe a sintonia melhorava. Então resolvi o problema trocando a antena de GPS antiga pela antena que o vendedor adicionou no kit e também mudei a posição da antena GPS para uma coluna da porta esquerda na altura do painel da carro- essa antena tinha o cabo menor. O FM melhorou. Mesmo assim, tenho dificuldade de sintonizar a frequência de 100,5MHz e algumas outras. Conclusão: o rádio FM dele é ruim mesmo.
