GH 337 Firmware needed

Hi Guys,

i have an old (or should i say ancient?) Ericcson GH 337 phone that i
just screwed up by entering "Yes" to the Flash ? Question in the
secret menu. I only wanted to reset the phone but unfortunately i had
12V connected to Vpp Pin at that time and so the Flash Memory was
erased completely.

Is there anyone out there that has a Firmware File for this phone so i
can revive it ?

Best Regards,

Tom
