How Can I Pass Bootloader (Huawei Y200 stuck logo/ Boot-Loop)
I had the same problem with my y200. 


Go to huaweidevice.com and download the firmware. 
Extract the folder downloaded and copy it to the SD card. 
Insert the sd card into the phone. 
Press vol up &amp; down key at the same time + power button, then a message installing package comes up. 
Then wait until the phone reboots. 


That's how its done
