Fixing V3 ringstyles- By Thomas
Connect to P2k tools with V3, then click the refresh button it will load the files in your mobile. Next in the folder tree drop down you will see the audio folder, Hit the all silent button at the top of P2k tools, delete both MytoneDB.db and also Temptonedb.db, then click fix MelodyDB button at the top of p2k tools, then click the restart button. Then go backinto ringstyles and it wont kick you out. If some ringstyles let you in my other kick you out just keep doing the guide again till they all work.
