I will let you know, so far i had to buy a 6 month suscription in drbios in order to download the dump, right now i'm about to test it. ( i dont know how to change serial number, any help?)

About the charger, it does nothing BUT i tried with a i7 dump (and it charges and powers just no video) which is GOOD and close to confirm efi failure

Are you flashing a dump from drbios?
I'm sure you've reset the SMC.
There's a blog on this site about replacing the serial. You can follow that for the most part, except you probably won't find <model number> in the drbios dump unless they've been poaching from here

Sure,

You were correct i couldn't find model string and i flashed it like that without changes and... it CHARGES but didn't power up

The best results i had with one cleared dumped from a1502 I7 from some user here in the forums (mine is i5) which powers on and charges but NO VIDEO

Please see attached file my S/N is: C02LN9FNFGYY (A1502 EMC 2678 INTEL I5)

THANKS AND BEST REGARDS
