Help lg f3 stuck on logo after unlocking

[rachid]

the phone was working until I entered an unlocking code. the unlocking was successful but when it rebooted, it got stuck on lg logo. the only thing I can do from there is enter download mode or factory reset . both didn't help. I spent the last 24h browser the web with no success . any idea?
thanks

What do you mean by "unlocking"?

i meant sim unlocking code, but never mind , i fixed the problem, used kdz to flash a mirror file of t-mobile firmware, it's up and running again. thanks anyway .
