If you have difficulties to get in recovery/download mode
Hit volume up and keep pressing. Add startbutton and keep pressing and for last add powerbutton and keep pressing.
Keep pressed all 3 buttons until the phone shuts down and startup again (don't stop pressing in between). Recovery screen will show up.
If you do it this way, no need to pull out your battery first.
For me it works all the time.
To go in download mode just change volume up to volume down.
