Hi, I'm in France, but macunlocks is located in london UK,
it should take a week or two I think
I recommend you talk with the guy by mail before to set up things et give him your right serial number
May the chip be with you ;)
Ok I have finally succeeded to reboot my mac,
thanks to https://macunlocks.com/
I've ordered a EFI card, and I gave them my serial number.
5 days later, I simply put the card where it belongs and bam, my mac booted like never happened before
I had a long discussion with a senior apple expert about that on the apple repair center online,
I explained my situation in detail.
He is surprised that verbose mode and online mode won't work, because they are the first to be called, even when the classical EFI boot is corrupted.
I'm in the same position actually,
I need to reprogram my chip.
Could you give me a link to a dumped original firmware to spare some time ?
Indeed I already spent many hours to find those explanations ...
Thanks in advance
My first attempt in a apple premium reseller store was "you need to change the motherboard", for approximatively 700$ (650€)
I'm very interested in your expérience, if Apple agree to do it, may be a simple flash of the EFI won't cost that much.
Ps : I didn't dare to say how I break my macbook...
I tried to boot on a USB hackintosh stick I prepared for another project on my real macbook pro and sadly I confirm this is a big mistake.
My EFI boot is not showing up anymore.
I saw the clover boot menu once and then black screen.
Reset SMC and PRAM did not work
Does anyone has an idea to...
