I've scoured the forums only to find no real answer to this problem so I thought I'd give this a shot.
Ok, so I've got an Alltel PPC6700 running Helmi's 6.1 with SDHC drivers. I also have a Transcend MiniSDHC Class 4 4GB memory card (FAT32). When I put the memory card in, the phone instantly locks up. Not slow down, but locks up the whole system. When I take it out, it unlocks the system and everything works fine. I'm using the SDHC drivers that came with the kitchen. I also tried a file called SDHC.777.cab and no joy there either.
Anyone have this problem and, possibly for the love of God, a solution?
