Q: restore firmware for macbook pro 13 mid 2009

Hello everyone!this is my first time using the support community so forgive me for any rudeness and sketchy english.

 

I recently purchased a used mid 2009 macbook pro 13" with no disc on it, i installed a new empty ssd 120 gb drive.

I asked a friend and he downloaded and made me a bootable usb with osx on it (lion). i successfully instaled the osx and got the macbook running and it was perfect.

I decide to update and went all the way to el capitan wich sucessfully installed. after the update i was trying it out, simple web browsing, when suddenly, out of nowere the mac shutdown (plenty of battery left and the led indicator confirmed it) and hasn't booted since... when i turn it on the led indicator flashes and it gives out the s.o.s beeping sound (3 short beeps followed by 3 long beeps and then 3 short beeps) the optical drive makes its usual looking for boot noises and the fan keeps spinning, i tried removing the battery for 10 minutes several time and nothing..i read a lot about ram issues tested with only one stick at a time in both slots and no improvements..bought a fresh pair of 2gb 1066mhz hynix pc3-8500 ddr3 sticks as recommended for this model and replaced the old ones..did nothing.

I have no original discs just the macbook itself and charger.Also tried booting from the usb drive ..no good.. tried booting in revovery mode..nothing only black screen and beeping sounds.

I have researched and read a looooot online and in apple discussions such as this, and found it to be the sound warning for bad/corrupt efi rom(as opposed to the majority of people stating it was a ram issue) wich needs to be restored or flashed..however apple doesnt provide or at least i cant seem to find a restore cd image for my particular model i know it's the macbook 5.1 (a1278/ emc2254). Is there no solution for this? please help in any way you can suggestions welcome!

 

Thanks

MacBook Pro, OS X El Capitan (10.11.4), mid 2009 13"
