My lenovo tab 3 7 730m tablet has bricked and i can not find the sp flash tool firmware for it. I just find a similar firmware As tb3-730x but when i flashed it the imei was lost and i found no way to restore it.i tried to make a backup from another 730m device but i can not backup "preloader"with this command ...ge/sdcard1/preloader.bin bs=512c count=512 skip=4 ,I am taking this error "block size `512c': illegal number",made a preloader without number 512c,and flashed to tablet,now i can not flash anything,gives me this error in sp flash tool "error 5000 S_AUTH_HANDLE_IS_NOT_READY this is a secure base-band chip please select the authentication file first". So if anyone has a experience,thanks to share it to me.
