New Stable China Version: V7.1.8.0.lhncnck

Apr 28, 2015
Hi, can anyone suggest if will be SAFE to update OFFICIAL CN Stable over this I have: MIUI 77. \Stable (LHNCNCJ) via Updater app. I have sms for bootloader unlock by Xiaomi, but the phone could not enter fasboot mode by pressing volume down & power buttons so I can't start the procedure for bootloader unlocking. If I update the Official China Stable will the Fastboot mode be available? Thank you
