ZTE Racer: ZTE-U X850 different camera model/driver

[Guest vitorgatti]

I bought a ZTE Racer X850 that has a different camera model or driver.

The stock ROM can access the camera's hardware, but no custom ROM from this forum can. I receive a message "no camera hardware found". Using the default camera app or any other.

For the record, this is a Brazilian ZTE X850 from the carrier TIM. It seems that a ZTE X850 from carrier VIVO has the camera working with custom ROMs.

I'm at stock ROM now and installed Android System Info app to get information about this model and camera.

As it follows:

----------------------------------------------------------------------------------

Clockworkmod Recovery installed without problems. Rooting was OK too.

With custom ROMs (tested all from this forum), everything seems to work fine, except for the Camera and the Call buttons.

I've searched ZTE's Brazilian website, but couldn't find any source code for this device.

Now the questions are:

- How can I find which camera driver is my device using?

- Is it possible to use this driver from Android 2.1 in a custom ROM with Android 2.3?

- In case all is possible, can someone help me to create a custom ROM with this new driver?

- Is it possible to make the Call buttons work as well?

If someone needs, I have a ROM backup made with Clockworkmod.

Thanks in advance

I have same problem, I tried putting some files in the lib/ of 2.1 to 2.3, but the camera still does not work: /

[Guest LeU]

Same problem here too

[Guest TigTex]

AFAIK, the camera is a kernel module. It's included in the kernel. I'll check if we have any zte-u x850 dump with the boot.img in there and i'll see what can I do.

edit, i can' do nothing... kernels are 1mb diferent in size.

Do any of you already tried to flash boot.img from the original rom in a 2.3 rom? It may brake a lot of things, but if camera works after that, it's a start. Be careful though, always make a nandroid before doing this.

edit2, I'm going to take a look at libcamera.so source, i have no idea what to search for...

[Guest TigTex]

ok! I may have found the solution!

The zte-u x850 has a different hardware, it's true.

How to solve? Well I need that rexchun posts how he compiled his rom.

The zte racer (normal) has this camera sensor enabled (copy past from the kernel config)

CONFIG_MT9T11X=y

The zte-u x850 has this one

CONFIG_MT9D115=y

CONFIG_MT9D115_QTECH_SUNNY_SOCKET=y

CONFIG_MT9D113=y

CONFIG_MT9D113_QTECH_SUNNY_SOCKET=y

That's the only difference between the 2 kernel config files.

So all I need is the 2.6.32.9 kernel config and source. There are some kernel sources but wifi doesn't work...

I'll contact rexchun and i will keep you updated

Could you share or edit your .config file of your ROM?

[Guest vitorgatti]

Thanks a lot, TigTex! I hope you manage to compile a working-camera ROM for us :D

EDIT: I tried to restore boot.img from Stock ROM to a 2.3 ROM here and no, it didn't even boot. Went back automatically to recovery after trying to boot once :P

Did you try this rom?

Your camera should work it.

I checked kernel config:

CONFIG_MT9T11X=y

# CONFIG_MT9T11X_QTECH_MCNEX_FPC is not set

CONFIG_MT9T11X_QTECH_MCNEX_SOCKET=y

# CONFIG_OV5642 is not set

CONFIG_MT9D115=y

CONFIG_MT9D115_QTECH_SUNNY_SOCKET=y

# CONFIG_MT9D115_QTECH_SUNNY_FPC is not set

CONFIG_MT9D113=y

CONFIG_MT9D113_QTECH_SUNNY_SOCKET=y

I´ve already tested, but didn´t work.

Just tried here too, it didn't work... :(

[Guest vitorgatti]

Confirmed: the Brazilian ZTE Racer X850 from carrier VIVO has the camera working with custom ROMs.

Just installed Mooncake 1.88 from TigTex in a friend's Racer and it worked.

In this model, it works without crash? With mine (TIM) I need remove the battery 2 or 3 times a day.

Yes, my friend is using without problems (VIVO carrier).

[Guest willngton]

Here are the diference (orkut zte community brazil)

ZTE - 850 From Vivo has : MT9T112-3.0MP-AF camera with autofocus

ZTE - 850 From Tim has : MT9D113-2.0Mp-FF (I think thas this have no autofocus)

:)

Maybe it's could help.

X850 from Tim has 3 MP camera too.

In my tests using the kernel Blade of TomGiordano, the module that recognize the camera is MT9V113 in ZTE Racer Brazilian TIM.

Check my tests here:

http://android.modaco.com/index.php?s=&amp...t&p=1728188

I'm adding the ZTE Racer in CyanogenMod Branch to build for he. I have an problem with screen bug after boot the phone.

I'm trying to identify this and fix.

If you need test to check if really is this module, i can upload the kernel to update in the tigtex ROM. So you need ADB working in your PC and do some shell commands to see that camera is recognized. But the camera application don't work.

[Guest gleidson]

It did not work.

It's still giving the message: Unable to connect to the camera.

[Guest brothermga]

Today ZTE has released an official version of the Android Froyo for Tim X850-U.

[Guest vitorgatti]

I think I have a solution, but as this is a problem only Brazilian users are facing, I'm going to write in Brazilian-Portuguese:

Eu tenho a solução!

Aparentemente a ZTE Brasil está fazendo recall desses aparelhos da ZTE X850 modelo TIM.

Entrem nesse link, liguem no número apropriado e falem sobre o problema da câmera no modelo da TIM que eles já até sabem o que é!

http://www.ztebrasil.com.br/support/zte_quick_collect/

Dei entrada na minha reclamação, esperei alguns dias e me retornaram da ZTE já começando o procedimento para enviar o celular a eles que eles vão arrumar a câmera. Provavelmente vão trocar o hardware da câmera pro mesmo modelo da VIVO, o que vai fazer as ROMs customizadas aqui funcionarem perfeitamente a câmera!

Corram atrás que não tem erro, a ZTE Brasil está ciente desse problema com a câmera (por ser diferente do modelo oficial, que o da VIVO segue, por exemplo) e está arrumando o aparelho de quem reclamar!

:)
