-Used flash wizard pro 5.0 on my D500 to update for -Gemini_200_DM500- image, all looked ok in the procedure, but my D500 starts with a black screen and do nothing....
-Used the Null cable i Bought (6) with dreamup , but no connection (nothing at all)
-Made number (5) null cable from scrach, also number (1), still nothing.
-Then i thought it was all dead, so used no (7) and it seems OK !!!!
(I didnd flash with it yet, because is totaly different , and the only one that has no 5-5 pin, and also other changes)
I ll just go to work now, and when i come buck, i will be really sleepy, but i have to test the dawmn thing....
Please tell me, should i Do the flash with that cable?
Should i try gemini ? or the original first? what version ?
Anything else i should be carefull of ?
THANKS a lot, and sorry for my english.
