6280 unlock problem

[Speed_Demon]

I recently unlocked a 6280 (Hutchinson Branded) handset. I had problems unlocking it with version 6.43 (branded). I've unlocked afew 6.43s before so I did'nt understand y this phone wouldnt unlock. I downgraded to 3.81 and unbranded the handset and the phone unlocked first time. After unlocking i flashed back to 6.43 (unbranded). Phone came back to weeks later, when u power on the handset it displays Nokia logo and then screen just flashes white. I did software (v6.43 unbranded) and phone worked. Phone is now back for same problem. I had a problem with 6280 before branded with T-mobile software, 2 weeks after i unlocked it handset went contact service. I flashed it with 6.43 unbranded (and wrote back 308 backup after unlock) and handset has never been back.

Any ideas about H3UK 6280??
I'm planning on flashing it with 6.43 H3UK software so lets see what happens, in the meantime i would like sum input....
Thanks
