Failed to load Recovery mode One of my friend had a Huawei Y210, it locked because of so many wrong pattern attempt. Unfortunately he hasn't google account to login with it.

I want to hard reset it but it fails to load Recovery mode by pressing Volume Up + Power for more than 10 seconds or less!, I tested any key combination but only it normally boots and shows locked screen. 

I tried fastboot -i 0x12d1 flash recovery recovery.img and without vendor id, it only waits for device.

Also I added 51-android.rules to udev and restart udev but nothing happend and only wait for device.  

and adb only waits for device.

I have no idea what I should do. If I setup a bootable sdcard, Can it boots from it? 
or like NoteII that can goes to recovery mode by soldering some resistors to a male usb connector and plug it, there is something like this?
Finally I found the way:

Turned it off and then connect it to computer, adb found it as recovery then i ran adb reboot recovery and then it reboots to recovery.

I found that volume up and down keys are semi broken and for this reason it could not to load recovery mode.
