I was following the instructions on how to patch an ELFpack on a W580i R8BE001 phone (Link)
And I got to the part where I patch the Elf, lib, and ico patches and it says not to turn it on, but me being the stupid dumba** i am turned it on, and the sony ericsson logo popped up and 1 sec later it disappeared, so I tried turning it on again, this time the logo did not come up, it just vibrated twice, now, when i try to turn it on it wont even vibrate, so at this time it is just a worthless piece of crap, i need help!

Reflash the main and next time follow the instructions more carefully.

2 other problems with that
1) Main as in the elf patch?
2) There is a byte mismatch and everybody knows not to flash it then so should I just try to find another one?

Main as in the Main firmware (the .mbn file)

If you get missmatch it means you have conflicting patches or you are using a patch that's not for your phone/FW

Edit:
It kinda worked, but some how the phone got disconnected during the flashing, didn't even touch it, and now whenever i try to nter bflash, it just disconnects the phone again... wow, my phone must be jacked up or something...

Is the battery charged?

i cant exactly tell because the phone wont turn on.

You must make sure its fully charged. If you can, use another battery or try and charge in another phone.

kk edit when done

Good luck

KK i charged it w/ my old se, and i tried it, but it kept on disconnecting as soon as I double clicked bflash.

Silly question: but have you added the QA (quick access) patch?

Yes i have...

bump

Are you using the latest JDFlasher, and the correct script?

Btw, don't bump.

yes, yes, and ok.
