Side not there is no step by step set of instruction for initiating updates properly.

@LEASoCal
there is a step-by-step guide using QFIL instead. It worked for me, though is not been officially approved yet. Use at your risk.

I had to also used QFIL to change R01 to R02 ( including making backup and restore via QPST).

After having R02 again no problem to use QFlash ! ( tried to change official R02 to modified and no problem, havn't tried to back to R01...)

@iamromulan
Any difference between R01 and R02?
I am using the 551E-GL Enginnering sample purchased in May last year. Will it accept R02 firmware?
