So after googling the serial number my phone thinks it is, it appears that the phone was unlockec with an octoplus box?
As the serial number appears in several threads for not reg'd on network.
What is now the best solution to the problem?
Find a shop with an octoplus box to restore my original serial number and reflash official firmware?
The rogue serial number is R31C80HWG1F
How likely is it that the Samsung service centre will repair this?
