Everything was working fine, till the 275 stopped working. Then I tried to do a bin upgrade to 276 - tried fwank, jvvh, saif, tronics and nikk - and then the sw-21 thing also. Nothing worked.
I am unable to complete the upgrade itself.
I identify the bin file in the updater and hit "write" when the P (in PUFF) shows up on swicthing on. But, instead of the usual 1% to 100% - the BL updater just does not start.
