I have a H30-U10 Huawei phone that is not turning on. when I press the power button, it freezes on the logo screen and stuck at there. The current ROM on the device is
H30-U10 V100R001C900B127. Also, I tried to flash same ROM and higher versions. But, I get following error:
dloading module MBR..... dload:update partition MBR failed Update /sdcard/dload/update.app failed
The entire process I did is based on this tutorial. How to solve this?
