I just bought the Kuman 3.5 inch touchscreen display for the Raspberry pi, and I installed all of the drivers correctly using this link: How can I install the KUMAN 3.5 inch-display? After I finished installing them, the system rebooted, but i got an error saying:
---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)
and I don't know how to fix it. People were saying
What I found was that the root file setting in the "cmdline.txt" entry that the >driver tries to install was incompatible with the setting in the original "/boot/cmdline.txt". E.g. The original cmdline.txt has "root=/dev/mmcblk0p7" where the driver tries to overwrite it has "root=/dev/mmcblk0p2". After changing "mmcblk0p2" to "mmcblk0p7", the system boots up and the LCD screen works

tar xzvf /boot/LCD-show-YYMMDD.tar.gz; cd LCD-show/; ./LCD35-show
Touch function will work after restart...
They were all mentioning various .txt files, so I tried looking in my pi's microSD card, but nothing was there. I do not want to flash a ROM to it, because my computer isn't working well and I don't have that much time. Is there any quick fix to this problem? Thanks!
