OK , you got me there... I did not go back and get your chip model from previous pages in the thread, my apologies. But, then again; it wasn't my responsibility to be sure it works with the programmer. Even so, check the voltage of the programmer as I have mentioned before, there is likely a capacitor draining the voltage being supplied to the programmer and the chip which will cause it not to read. Use a usb 3.0 port if needed because they usually have more amperage. You could also plug in, but not power on, the mac to supply whatever is draining the power, if in fact that's the issue. Glad to see it is in working order and not fried yet. This means we still have another avenue of approach.
the programmer works perfectly, I managed to read the spare chip I received, I saved the dump on my hard drive. I could put it here, so everyone could use it, but it's not the original dump, is the one the company who i bought the chip put on it (largest company in europe selling chips for stolen property, just like this site, ahahaha).
no problem with voltage, at all. but again, you guys know the easy machines to solve. No imac, no mac mini...
The voltage may not be fine because ISP (in system programming) a chip is much different then just a single chip. Check the voltage at the chip and stop being stubborn. You need to test VCC to GND....
I got the last few posts aimed at both of us and this guy is an ass and I can't believe your still entertaining him...your a better man than me Ghost!!!
Me, my iMac with freshly written fw, my macbook pro with freshly written fw, my trusty PI and soic clip (as I'm not scared of writing a chip) are off this thread before I reply on his level which I'd rather not do!
Good luck Ghost
Some kind of personality disorder it seems ..all thanks and niceness a minute ago, then back to ranting lol...someone skipped his meds I think. Well done for staying polite to the end Ghost. If I'm ever over your way I'm buying you a drink haha
ok, back to topic. So i should try to read the chip with the machine connected to electricity? What do you think about the cell battery in the logic board? I tried to read the chip without that battery, should i try with the battery on?
I don't trust you any more, not you and not your knowledge. It's always said to read the chip without power on the board, otherwise the chip will get 2 times the power and will get fried, so no, thank you but no. I will not go that route. I will leave it as it is, or cut the chip legs and solder the new one.
Cutting the legs may damage a pad but I think if you're more comfortable with that method then go for it. Supplying power to the board with the machine off will not cause damage to the board. Also the chip can handle more power (amperage) than you will be supplying it. And the voltage will stay the same not double if that's what you meant.
the chip is on the other side of the logic board, on the inside side, so i have to take it apart to connect the clip. if i take it apart i can not give it power anymore, i could maybe connect the power supply unit... even with the board off.
In any case, why everyone always say to read the chip with the power out of the board, ALWAYS, and now you tell me to do the opposite thing? don't you think it makes very little sense?
I can understand the controversey, because it's the safest way to do things. But I am not asking you to turn the machine on which would be dangerous. Like I said I have a schematic for the board. If you don't feel comfortable please try your way first.
