Hi guys. I had the unfortunate pleasure of sending my Samsung S5620 phone to my local Samsung recommended service store. They have been a nightmare ( but thats for another day). Basicially they have sent my phone back to me , and its saying "SP lock" and prompting me to enter a code . The last time they sent it back to me it did the same, and then locked as soon as I tried one go at the code. Can somebody please advise me what this code means, and how I can safely get the code ? Thank you.
