Kies brush machine, you may not need to brush machine, if you have the account of Yi Rui administrator, you can unlock Yi Rui with a sweep; Use Samsung

If kies brushed the system, it wouldn't unlock the bl lock, and Yi Rui didn't know it. However, this software is not open software and needs an internal domain name to download; When you finish brushing the machine, there will be no juvenile pie. You can do it and cherish it.
