Hello, I have a little problem after installing clockworkmod with tutorial inside this page http://xdaforums.com/showthread.php?t=1774560 (can't post outside link)

Instructions:

First time flashing CyanogenMod 10 your device, or coming from another ROM?

1. Root the device and install ClockworkMod Recovery. Instructions are available here.

Installing the ClockworkMod Recovery

This guide applies to a Samsung Galaxy Tab (GSM) on the stock 2.3 release. If the Samsung Galaxy Tab (GSM) already has the ClockworkMod Recovery installed, skip this section.
