[usufx6]

Recently my brother sent me 5230 mobile wich is network blocked. Is it possible to unlock network blocked by changing product code then flash. Means change product code to unlock phone product code then download unlocked phone firmware flash with jaf or phoniex?

You can buy unlock code from network provider.

@ usufx6, Jual is correct if your phone is locked to one network then it needs that networks unlock code. But if im reading your words right your saying its blocked by the network. That is a completly different thing & they will not re-open that phone without proof of ownership.

Its possiable if flash software don't copy sim restriction file from phone current firmware and replace it again after flash your phone with new firmware. As far as i know phoneix do that because it developed by nokia. May be jaf can unlock by this way. I never test it you can test it yourself. I will come back if i got something new.

here in holland you can go to the shops and they will change it for € 10,-
but i think you also could do it with software

Yes it can be done by jaf unlocker interface. Some phone need box.

seems to be a long process. y don't you try codes to unlock your phone from your network. get your unlock code either from your service provider or from other online providers like Mobileunlocksolutions.com and unlock your phone.
