Hi all
I have got a problem programming the BBS01. It can read the flash, but it wont allow me to write. Also when I read the flash im getting some very strange values ( 14 for all assist levels ) which is definately not correct. Have anyone seen this issue before ?
See attached screenshot

I've had no problem tweaking mine. Are you using the stock bafang program or the tweaked one? I wonder if the Speeed app on a phone might work? That works for me too.

Is the issue the prog cable ? Some of the cheap ones don't work.
