hi I have a Huawei s7 slim tablet and it wont boot properly everytime I switch it on it goes to a blk screen with white writing which reads : "enter into fastboot mode , you can press home + back to reboot ".I have tried to re=install the original updata which is v100R001c187B016 (dload) already from sd card and the tab went into fastboot mode and the process was done and it read "OK" with 100% bars but when I took the sd card out and battery the tab went back to that STUPID SCREEN ! PLZ HELP !
