ROM / Firmware/ Brick Recovery for 7" Android Head Unit AC8227l YT9217 YT9218 1/16GB

Bro ,

Now I did download only and flash done the new firmware but with the new firmware still stuck on restart loop..

I tried " format all and download "

But giving me this message .

I did copied preloader and metazone you have given above to the firmware folder.

? Just add 'preloader' file manually, because it is still missing from the list, that's what the program tells you.

Edit: Scatter file has writed to look just for 'preloader.bin' so it didn't find it because of different filename.

 

[ericgonzalez]

I understand. it is as I described above

Can I press the two contacts of the test point with needles? I have tried to do the test point but nothing the pc does not recognize the usb port

Yes you can, everything that works is good.
So pc tells you that 'doesnt recognize the device'? Or just nothing happens?

If it 'can't recognize the device', then there's probably something wrong the usb cable you're using or with the drivers.

I used adapters from 'usb c' to get 'usb a' to 'usb a', and when the adapter is loose, I receive info that 'the device is not recognized' when I fixed the cable, the process begins.

 

[ericgonzalez]

Sí se puede, todo lo que funciona es bueno.
Entonces, ¿la computadora le dice que 'no reconoce el dispositivo'? O simplemente no pasa nada?

Si 'no puede reconocer el dispositivo', entonces probablemente haya algún problema con el cable USB que está usando o con los controladores.

Usé adaptadores de 'usb c' para pasar de 'usb a' a 'usb a', y cuando el adaptador está suelto, recibo información de que 'el dispositivo no se reconoce' cuando arreglé el cable, comienza el proceso.

¿Será que los drivers que instalé no son los correctos?
tienes los drivers? a ver si los cambios a ver si es eso

I'm glad everything works.

But yeah, Unfortunately.. Many people have already mentioned that the RAM and storage is often faked. Even android 10.1 its a 8.1for real. You could try to write down the names of the ram chips from the board and google it how much you've got, just for sure.

Ps.
You can do a launcher update thru usb 'android upgrade' it contains 21 ui sets. XY92xx UI 1024X6001280X720 --21 checked and working

Thanks friend but nothing my pc when I connect the radio via Usb does nothing it's as if it weren't connected, I'm about to resign myself that I lost the radio

 

[Dragon_159]

Her şeyin işe yaramasına sevindim.

Ama evet, ne yazık ki.. Birçok kişi, RAM ve depolamanın genellikle sahte olduğundan zaten bahsetmiştir. Android 10.1 bile gerçek bir 8.1'dir. Tahtadaki ram çiplerinin isimlerini yazıp Google'da ne kadar olduğunu aratabilirsin, kesin olarak.

Ps.
21 ui seti içeren usb 'android upgrade' aracılığıyla başlatıcı güncellemesi yapabilirsiniz. XY92xx UI 1024X6001280X720 --21 kontrol edildi ve çalışıyor

9I updated 9216BJ to android 10 but it is stuck on boot logo, can I be successful with sptool?

Thanks bro, you are continuing on surprising me ..
I wouldn't make it without you help.
I will try UI's you have given.
I liked AGAMA luncher I like it, but it's not build in like these UI's ..
I noticed voice is lowered after flashing new firmware especially on Radio,but it's still better than stuck loop because it was draining my car battery, I was willing to through in the trash ,but I wanted to give it try because I knew it was firmware problem.

Are you connecting unit thru 4pin usb from motherboard? and are you plugging in the power?

9I updated 9216BJ to android 10 but it is stuck on boot logo, can I be successful with sptool?

yes, read the conversation above you have written everything how to flash it. you can use firmware from link 9216bj/9216cj.

I also noticed that the sound has a completely different volume. I haven't tried to find a solution yet but ill do.
I've had the radio for a few months but I haven't used it in the car yet because I want to configure it properly.

pleasse help where tespoin mainboard JAC8229B1_ver_0.5

 

[Dragon_159]

Üniteyi anakarttan 4pin usb ile mi bağlıyorsunuz?

evet, yukarıdaki konuşmayı okuyun, nasıl flaş yapacağınızı yazmışsınız. üretici yazılımını 9216bj/9216cj bağlantısından kullanabilirsiniz.

Ayrıca sesin tamamen farklı bir ses seviyesine sahip olduğunu fark ettim. Henüz bir çözüm bulmaya çalışmadım ama yapacağım.
Radyoyu alalı birkaç ay oldu ama henüz arabada kullanmadım çünkü düzgün bir şekilde yapılandırmak istiyorum.

Bilgisayar kullanmadan başarılı bir şekilde yükseltme yaptım, satıcı bana bilgisayar kullanmadan usb'den nasıl oda kurulacağını söyledi, şimdi sadece Zlink'in etkinleştirilmesi gerekiyor

Im asking just to make sure, did you connect the 12v power supply when connecting the usb?

 

[Dragon_159]

Sadece emin olmak için soruyorum, usb'yi bağlarken 12v güç kaynağını bağladınız mı?

n You can install software without using sptool and a computer, check out the topic I opened.

Dragon_159 Great news Bro

 

[ericgonzalez]

Im asking just to make sure, did you connect the 12v power supply when connecting the usb?

If I connect the 4-pin usb, but how do I connect the 12 V power supply if the radio is outside the car?

 

[Emilson]

Omg... such a misunderstanding...
Sorry but you have to plug 12v to make it work, thats the whole problem of 'not detecting the device'.
I thought you read about it from a conversation in the thread.

Im using an 12v ac adaptor from my old internet router. You can try to use some car battery charger/rectifier/jump starter however its called, anything that gives you 12v.

Can you send me an image to see what the adapter I should use is like?

 

[ericgonzalez]

And what part of the radio does that adapter connect to?
