*************************************************************************************
note alternative:

For users familiar with flashing and interested in a smooth fast process: you can flash combined first, and then *immediately* after that - without one 10th of a second of booting - directly continue with flashing the vanilla. The other way round doesn't work due to a bug in NOLO - so after flashing vanilla you need to remove battery to recover
