MBP won't turn on after EFI flash

My mac boots up but the boot up line only gets half way and hangs. I did wipe the efi a couple of times as the 1st dump I tried was wrong but I didnt re flash with original efi dump, I just wiped and used this dump and now Im stuck. Any help would be appreciated. Thankyou

i can't check your dumps from my phone, but...

after flashing, are you booting the mac installation? you should be booting USB install media

If you got the dump from the repo, it needs the serial number entered.

Search for "model number" w/o quotes and replace the entire string from < to > with your serial

Hello, this is my first post. Love your site, very nice design.

I'm having this same problem with an iMac a1311 2428 i5.
I used a raspberry pi 3 to do the dumps but since i wrote firmware, the mac won't boot anymore. The fans spin for a second then off, repeat. I have tried flashing both modified and original with same result. It posted fine before
Any tips or advice would be much appreciated! Thanks.
