What do you mean, that your camera is not hackable? Have you tried to hack it and failed? Or that your firmware version is 1.34?
You may failed to apply the firmware for various reasons and yet your camera could be hackable.
It is really about your firmware and not serial number. You can check your firmware doing this steps:
1) Turn camera off, and set the Drive Mode lever to Single
2) While holding both the "Display" and "Film Mode" buttons, turn the camera on.
That's it, now you can find the "ROM Backup" option in the setup menu. And, you can use the following to get to the error and counter menus:
3) With the camera on (from last step), press and hold the left arrow button and the "Menu Set" button together. Keep holding them!
4) While these are pressed, press "Film Mode". You can let go of all the buttons now!
Now you'll see the error codes displayed, you can use the arrows to navigate and you can hit Display to go to some other similar display of codes. Note, that in the 2nd and 3rd code display pages, the LCD is getting output from the sensor.
If you repeat the "Left Arrow" + "Menu" + "Film Mode" button press you find the "Camera Info" screen showing firmware version, a serial number (probably the main board), power cycle count, shutter count, and strob count.
