I have a k810i that I have tried to unsuccessfully to unlock. I have used setool 2 lite v. 1.11. Please can someone help me to rectify the problem. Please can anyone explain the firm ware patching process to me as well. I have read numerous guides on these forums which I found were no help. Thanks.
