Hi Matty, I'd like to briefly reply to this previous message you sent me:
1) why should I remove R51 resistence (also if the cable is working fine?)?
2) I updated suggested ept file on ftdi by Mprog;
by PonyProg2000 I updated firmware (1.92) + eeprom (vers. 6 for 11.11.5-12.12.0 eeprom 512 rl.hex) even if probably is not a 512;
3) by PonyProg2000 set fuse and bits on security and configuration bits (it should be 256b words), this time I did NOT use v. 512b words fw;
4) power supply with a proper voltage stabilizer: 12V
5) 12V power supply applied to LM7805, GND connected as pdf procedure
GND of 12 V to GND of LM7805, everything works fine during the uploading/flashing procedures.
6) after every flashing and verify told me that check was successfull (ok).
Hope it helps.
Thanks again to all of you.
Cheers,
sgtp

First step that you have to do is to remove the R51 ( I saw this resistence soldered in your hardware )
The you said that you did this and did that but please tell us what exactly you are doing?
What programmer you are using, what software you use to flash the Atmega
You said that you set the Fuse bits but you didn't tell us what fuse bits did you use it
Please share pics with fuse bit set it
Ask Mr. Mladen76 how he did first time. He if he rememebr he said as you now that he set well the fuse bits in the Extream Burner software and after I took a look in his compouter he realized where he did wrong
Now i do not help anyone like I did with him in that time. Now I only can give you advises and tips if I want. So share pics adn tell us step by step how you did.
I forgot
What power supply did you use? 5V or 12V?
Where you plugg the power supply?
Did you solder together the power supply GND with the programmer GND?
I ask you all of this to figure it out what you do there exaclly.
Even you think that you did all the steps as at the book but maybe you forget anything and thats why you cannot flash the Atmaga. Or Atmega could be blocked. who knows
As you could see in Mr. Fantomel collection he said there 512b words firmware but actually there is only 256b words firmware. So if you di a wrong step and you set the fuse bits for 512b words firmware then of course that your Atmega it is not flashed well
Good luck
