Has anyone else experienced a SDHC card disconnect after using NVBackup? I'm currently using the 680's slot driver to enable SDHC support on my 700p - and I'm guessing that after the backup completes, the driver is reset and the card disconnects. Is there any option to exception a file from the backup?
Try Treonauts. There is a link to a file: SDIO 8gb Hack.prc Follow the instructions to the letter. This will most likely fix your problem. However, if you ever need to restore, do not select that file. Put it back on the phone the same way you did the first time. I suggest keeping a copy of it somewhere else.
The link is contained in a blog about his 8gb card.
