that flashing it with usbasp programmer. It may be helpfull for those who 
doesn't have FTDI cable or have some problems with bootloader.

Here is manual how to fix firmware missing without bootloader:

1. Download precompiled OSD configurator with this patch.
2. Run configurator and select File -> Reset EEPROM to Hex (writes all default 
OSD  params to file)
3. Configure params and OSD elements how you like.
4. File -> Save EEPROM to Hex (writes configuration params to file)
5. Download OSD flash 
(https://code.google.com/p/arducam-osd/downloads/detail?name=MinimOSD_20.hex&can
=2&q=)
6. Burn flash
7. Burn default params (from step 2)
8. Burn config (from step 4)

I'm using Khazama AVR Programmer (http://khazama.com/project/programmer/)
Just run it, select valid AVR and use Command -> Write FLASH and Command -> 
Write EEPROM

Burning process using this patch is little harder than using original updater:

1. Burning FLASH.
2. Burning EEPROM default values.
3. Burning EEPROM custom values. (OSD element placement etc.)

Steps 1-2 done only once. Step 3 is repeated after changing something in 
configurator.

===

For the step 1 just download MinimOSD_20.hex and burn it using programmer 
command "write FLASH".

For the step 2 run configurator, select "File -> Reset EEPROM to Hex" and save 
to file default.hex. Than burn it with programmer command "write EEPROM".

For the step 3 run configurator, configure OSD elements how you like, select 
"File -> Save EEPROM to Hex" and save to file myconfig.hex. Than burn it with 
programmer command "write EEPROM". It will overwrite some default parameters.
