[Q] [q] lg logo pops up and nothing happens topic

I have a problem here.

I flashed a rom last week. It swapped my internal and external memory. After doing that I accidentally removed my sd card and now only the LG logo pops up. Tried reflashing it. Took it to a local mobile repair center to update software but no success.

Any help or advice appreciated...

Model No: LG OPTIMUS L9 P765
