MacBook Pro A1502 EMC2835 problem

Hi everyone,
Ok so i have this problem.

I have a A1502 with EMC 2835 that i removed icloud from but now it doesnt boot up again.
I'm using Sofi SP8-B programmer, I need to remove the chip from the mainboard to program it because the programmer doesnt recognize it other way
I have tried with the original bin file, the original cleaned, and some others that i found on this forum but anyone worked
at this point i dont know what can be failing, any help will be appreciated

i will attach the Bin files that i used in case that someone wants to take a look
*a1502s3.bin is the original file
*a1502cleaned.bin is obviously the cleaned original
*cleana1502orj.bin is the one that i downloaded from this forum

Hi, it doesnt do nothing, not even spins the fan...Its like nothing happens when I press the power
But it charges... when I plug the charger the light turns on green, then changes to orange, and stays there on orange

hi,
wich brand chip you programmed?

Hey,
It is a Winband 25Q64FVIQ
Im trying to post the pictures, but for any reason the page crashes

hi,
If a chip burns, can I still read, erase or programm it anyway??
Because i can still do it..
maybe the programmer isnt working like it should (?

i think you soldered the chip not very good ( one or two pins are not connected well)
Or one of the mini resistors next to the chip are loose
try to solder again heatgun use flux and when you see the solder is melted press the chip with a knife ore something else in his place and hold till its hard

Hey,
thanks both of u for suggestions...
Im going to try and solder it again right now, lets see what happens, i will keep you up with it...

About the Raspberry, anyone will do it? or i need a specific model?
I will attach a picture of the setup so u can see it...

I cannot attach the picture.. dont know why but anyway here's a link to it

Hi,
I got the ame issue with the same model of Mac and the same EFI.

After checking tutorial for EFI unlocking:
- I got desolder EFI chip which is WINBOND 25Q64FV,
- read it using SPIPGM2
- but after dumping it to BIN I had chip erase issue which was caused by bad connection, I had managed it and erased
- I had edit BIN with WinHex then ERASED first occurance of $SVS as in instruction
- then program chip again and solder it
- then my notebook is bricked
- I had program again original dump but no results, bricked, I mind CPU is getting hot but no screen appears

I understand that in this case each of BINs are prepared especialy for ones motherboard so there is no way to flash it using other BIN ?
Could you check is everythng ok with the BINS ?
What could be issue ?
I had using SPIPGM2 with other BIOS and everything seems fine.

Thanks. I'd uploaded only original dump without cleaning $SVS, but anyway thank you for cleaning out the file.
Moreower problem still exists, when I solder in the chip my mac won't turn on and CPU get hotter, cooler won't turn on.
Is it possible to affect KBC while programming bad flash ? There is no additional KBC bios programmable chip in mac ?

Finally got the issue

Here is my solution:
- i get dump no 1 from one of the other post, thanks to mr. Leon the Professional
- i had changed the Serial Number then write clean ME region according to Ghostlyhaks.com tips
- i test my programmer hardware using acer motherboard is it correctly working: erase chip, program it with new bios from website, passed ok
- desolder chip again, erase it, program it with new dump no.2
- put more solder on motherboard pads because this efi is new flat one
- sodler it, and put MB back to case push the power, and suddenly after a longest time it turns on the screen yep
thank you Ghostlyhaks.com

I think something went wrong while dumping for the first time and the dump was incorrect, even looks like good one. Chip is the same all the time.
So for me helps downloading other efi dump from the same motherboard clean it and set my SN then write it back to chip.
I hope it helps someone in the future.

Hi..i have this problem with my macbook.. doesn't turn on..when I have removed the chip the micro resistor near the chip it has been removed taking away the right pitch..there is a connection near the resistor for make a jumper and repair the motherboard?thanks!excuse me for my bad english..thanks
