Q: Macbook pro 8,1 late not booting after SMC flash via rEFIt

Dear all,

To be synthetic:

I had kernel_task running over 300% with my HDD WD Blue

I replaced it with a SSD and the problem was still here...

I looked up into settings and found that i didn"t had the correct SMC and EFI version: see below:

Nom du modèle : MacBook Pro

  Identifiant du modèle : MacBookPro8,1

  Nom du processeur : Intel Core i5

  Vitesse du processeur : 2,4 GHz

  Nombre de processeurs : 1

  Nombre total de cœurs : 2

  Cache de niveau 2 (par cœur) : 256 Ko

  Cache de niveau 3 : 3 Mo

  Mémoire : 4 Go

  Version de la ROM de démarrage : MBP81.0047.B2C

  Version SMC (système) : 1.68f99

As you can see i dont have the correct SMC installed, and have an unknow EFI ... I dont know how i have the wrong SMC and EFI ..

I tried to install the correct SMC and EFI from el capitan but it said that i needed 10.9.5 version, so i moved on and downgraded to mavericks and when i tried to install i got a message that i can't upgrade the version ... (or it was not needed )

I tried to flash the SMC with rEFIt and it has succeed:

I used the 201MBP13.smc which is located on the .pkg of the  MBP late 2011 update here:

Ofc i have a blackscreen so can't do anything..

Tried SMC, PRAM reset, nothing

Now when i'm booting, the fans starting at full speed 10 second after the boot, then turns about 6-7 seconds and then the mbp shut down ..

The mbp is out of waranty

Thanks for the help!
