RM-75/6030b firmware update

**newegg1** · 07-10-2006, 06:34 AM

I have a RM-75 (6030b) that I had bought on the road to replace a dead phone. I want to change the frimware to either a generic Nokia, or Cingular. Right now it is Tmobile (I already unlocked it). I have been searching the net for 2 days now, and can't find what I'm looking for. Can anybody put me in the right dirrection or perhaps PM me some answers? Thanks

I'm in the US and I need the RM-75 version because of the bands. I have found all sorts of files but they were for the RM-74, european bands...

Just ran across your thread. Did you end up finding what you wanted? I just had my 6030b (RM-75) flashed by iUnlock with unbranded firmware.

Hello all,

I'm having a problem with my 6030b rm 75 ver.03. The phone has been locked up by T-MOBILE. The problem began when my sist has been wrong to enter code calculator for 5 times. I have tried re flashed with upgrading becoming Rm-225, now the stuff has no signal even there's no operator found. I have searching it manually but there's no help. I have also some T-Mobile phone which having problem like that. I would be very grateful if there would b someone giving me solution. Is it possible to make that the devices working normal while five times entering wrong calculate pass ???

Thanx
