I just took the A39 no shutter sound and with sound firmware and did a simple hex comparison, and I found that this block is different: hex 00621BB3 to 006222DA.

By doing the same thing with A53 firmwares, The same thing can be found.

I took the A40 firmware (with camera sound), and looked for the difference offset (attached). Then I set all the bytes to zero (00). I flashed my phone, and now I have A40 without camera sound!

Note that different firmwares have different offset on this block. Also, I do not take any responsibility if this damage your phone.

You can open the attached file with a Hex Editor. This is the difference of the sound/no sound firmwares.

You only need a Hex Editor. I use Hex Workshop. Then find the block of hex value, and set them to 00.

After you're done, just save the file, and flash the firmware with winmodo.

1. Hex Workshop or UltraEdit
2. You need to edit the firmware
3. Read my first post. I think you're not very familiar with hex editing, so I do not recommend you doing this.
4. Read: http://www.mobile01.com/topicdetail.php?f=10&t=2617

What should I do? Do I set all those numbers and letters in the middle to zero after I do the comparison? Well, honestly I'm not familiar with hex editing, however, I just wanna know how to get rid of the camera sound.
Please help if possible, thx.

其實如掌握修改firmware後,你可以自己製作照相的聲音

The camera shutter sound is in mfm format. In the firmware, all mfm sounds have an header "mfmp", and you can find one of them has a "shutter" word after it. That's the shutter mfm. The mfm has an footer like "trac..."

So all you have to do is, locate the block of hex (or ascii) of the shutter sound, try to copy it to a new file, and save it as mfm. See if you can play it with mfm player (on http://lostrebel.gsmhosting.net). If it works, you're on the right track.

Make your own mfm file, with approx same size, and replace its hex to the original hex. As long as you don't replace other codes in the firmware, then you should be ok. (i.e. only replace up to the 80 80 80 80 80 80 80 80 80 80 after that "trac...")
