If you are having issues getting into recovery mode you could try to write this script. Save it in the same folder as where you have adb extracted. hopefully you have windows bc i don't have a linux machine running and haven't tried one for linux.
Open up notepad and input this:
@echo off
adb.exe reboot recovery
pause
adb.exe kill-server
goto:eof
Save the file as *something*.bat (fill in the name how you like, I did reboot recovery.bat) and make sure you change the save as type to all documents. Plug in your phone and run it. I found this is much easier than trying to use the buttons to get there. hopefully this helps
