What should I do with a 3.0 firmware unit? I want to backup the NAND. Not sure which program is best. I was thinking of sticking to 3.0 firmware and just using NSP files to avoid firmware requirements. Also is there anyway to stay at 3.0 + FAT32 and split the NSP files? For whatever reasons I don't want to upgrade with 5.1 I know I can do this without burning efuses. I would just rather stay at 3.0 if possible.
