1. Download from the Market ‘root explorer’ or a similar program. I used the free ‘Super Manager’ with included root file explorer. You must enable the root function in Super Manager, otherwise you don’t see the folders.
2. root your Galaxy Tab –>
3. Within the file explorer you should go up to root map folder (in short: “rm”).
4. Then follow the instructions of Gadgeteer81. You can either delete the file or rename it.

To Fix Android going into “Obtaining IP Address” loop:
rm /data/misc/dhcp/dhcp_list
It seems to come from the fact that the phone requests its previous IP address to the access point, without any discover message, whereas the lease has expired from the AP point of view…
The previous leases are stored in /data/misc/dhcp/dhcpcd-eth0.lease and /data/misc/dhcp/dhcp_list. You just have to remove the second file (dhcp_list) to force the phone to start a new dhcp negotiation.
