Hi i have just bought this reader/writer. is it possible for one of you to make a .Bin file for me so i can get the macbook unlocked? and can i use this type of reader to do transfer the .Bin file to the bios?

In my opinion this programmer is garbage. Most of the time you would need to remove the chip and insert the chip into the programmer to write the file to it.

Sorry but that programmer is junk. I have one myself and over the past year I have never gotten it to work.

I can't see the site since it says it is only available in Denmark.

How many amps is it?

That is only 0.08amps, you need at least 2.4amps.

I also have the Sofi Programmer and it is honestly not worth the time to try and get it working correctly unfortunately As Cygnus said in most cases the only way to get it to work is to remove the entire chip out of its socket and program it then solder it back which, unless you're good at doing exactly that and have done it many times before, will probably ruin more than it's worth. Which sucks because I happen to like the GUI that comes with the Sofi, the Windows FlyPro app suits every need I could hope for in a GUI like that!

If you've got your heart set on keeping this programmer there is a way you can get it to work, but it would require modification. First you would need to swap out the connector clip, the part that fits into the socket on the Sofi itself. The stock version doesn't have the option for modification, but if you look at this one in the picture I have attached to this message you'll see there is 2 holes off to the side for an external VCC & GND to hook into. If you are familiar with vaping at all you'd know that a typical vape pen battery is exactly 3.3v so, for instance, you could take said battery and solder two connections from either end into the two spots on that Sofi clip and when you go to access an EFI chip it will work flawlessly I hate that damn error FlyPro gives you about "voltage fault" or something, this was the only way I could find around it. Hope it helps.

Thank you therealjayvi! You may be on to something here. I need to look for a rechargeable battery for this. Thanks for a great tip!
