Wipe iphone 4 system clean E-mail 此主題給朋友 [按此打開] [隱藏] Iphone 4 16g, with Limera1n jailbroken, 4.1. I tried to wipe the whole file system clean by writing zeroing data, but encountered the following problem: I successfully sshed into the device, and force the two partitions (root partition and media partition) to read only mode, but have to unmount the media partition before doing that. So when typing the following command \"umount -f /private/var\" the system returns the error with \"not a directory or special device\" So anyone knows what\'s the cause? Thank you
