Arrow build Jpeg from hex

Hi everybody.

I need someone to help me with this big problem that I have.

I have a device called G200R from cybergraphy.com its a GPS tracker and it has a camera that takes a pic, this device has a chip who converts the image to JPEG format and it sends the image data through the internet... in the end I receive a hex string which has the image then I should convert this data to a binary file but the problem is that this image data does not has a jpeg image format.
In some of the lines of data (or frames) I find the start of image (FFD8) and right next to this I should find the JFIF marker (FFE0), but I find FFFE instead, I never find the "JFIF" string (4A46494600), and I never find the end of image (FFD9).
At http://zionika.com/log.txt you'll can see some of the image data inside V=xxxxx... the other variables are position etc.
Update: A bigger log file http://zionika.com/log2.txt

Please give me a hand with this.
My email is gigatron_7@yahoo.com
Thank you very much.
