I'd like to share the knowledge I gained from the Vietnamese forums
To get into Stock Recovery of Xolo Q1000 Opus (Mobiistar touch Lai 504Q in Vietnam) do the following:
1. Hold Power button for 3 seconds till phone vibrates.
2. When Phone Vibrates, Leave the Power button.
3. Quickly press and hold the Volume up button till recovery loads (you probably don't have to hold it that long).
Note: The Stock Recovery doesn't allow you to flash ROMS to /system or /boot etc.. I don't know if its the same case after rooting though.
I have been lead to believe that you cannot flash any ROMS with the stock recovery.
Luckily, minhdangoz from Vietnam is working on an open-source CWM Recovery for this phone.
EDIT:
post kit kat update.. to enter stock recovery:
