File transfer problem between 2 k750i phones

[msa]

Hi

Just come across a problem which I am not familiar with. I will try to explaine best I can and hope you can understand what I am trying to say.

I flashed and de-customised Vodaphone K750i with R1L002 flash file (same as what the phone had Originally). Phone is working fine exept the following.

Now the customer and his friend who has another K750i phone, which has not been alltered in any way and is still on O2 network, tried to swap files using bluetooth.

His friend can access the de-customised phone and look into files etc but my cutomer can not do the same. Phone can be paird but when my cutomer try to access his friends phone (press services button on the phone) the timer barr comes on but nothing happens and it come back to the same menu.

My cutomer says he was able to do it before de-cutomisation.

I hope someone can shed some light on this problem.

many thanks
