hi guys,ChomsMaster you video of you tube machine a1534 show programming "in circuit",
but in the specification tell :
SOLUCIÓN
Desmontar el ordenador, ""retirar la BIOS"", editar el binario y reprogramar el chip.

please tell me? you desolder of bios? or not
You can disassemble it if you have to read it, otherwise you have to solder each wire to the connectors of the bios and it is very delicate since you have to know which ones are exactly, my recommendation is that you do it without disassembling the bios, soldering as it is Explains earlier,
ChomsMaster, my friend, I tried many times to connect wires or needles to the components. This board is small and components are tinyyyyyy. It seems impossible to make connections...
ChomsMaster I don't know how you're doing this but you are my hero!!
hola,he revisado otra vez las conecciones en mi a1534.y todas estavan bien
menos el pin 8 del bios que lo puse en el pin 2(PP3V3_G3H) del conector u6100
quizas desde ese punto, no le llega bien el voltage al bios

que creen?
What I personally think is that you do not read enough, I have already explained in detail where they should go and I do not intend to do it again.
Sorry for the delay @yolito, no i couldn't remove the password using the described way. There are tiny components and you should use microscope for sure. You should be extremely cautious because it may brick your motherboard...
I can read the chip, I edited the code, then when reprogramming the chip, it also works, but in verification it gives an error though... It's strange, because I also tried to program back the original code, and that gives no error, so i must be doing something wrong editing it. Which is weird, size was exactly the same and i edited the code just as i always did with other macs... please help!! If someone has a dump for this would be great. I can also send the original locked dump i have, in case anyone can help or edit it, thanks!!!
