Sorry for reporting again my little problem: Since more than an hour I began to upgrade firmware, but after formatting memory card with the GX100, I must constate, that the Template of the memorycard has gone and there is nothing to put the uprade-elements in. I can recover the Template, when I formate the card with Ricoh G700.
I must oversee something with the GX100. What? I tried with 2 cards, tried with two computers, made fotos, etc.
When I tried with a formated by G700 and put the elements in (by the G700 created Template), upgrade failed.
I can live without upgrading, but the phenomen, that template goes when formating seems strange to me.
