Default [Q] Can't update Samsung GT SPH-P100 to Gingerbread?

I got this old model of galaxy tab 7" from sprint but I stopped its services....

An update is available but when I install the update it only finishes about 1/4 of the installation and a triangle with an exclamation point appears.

I also tried manual update steps in the internet but a small triangle with exclamation point is also appearing.

Firmware: 2.2.1
Hardware: P100.08
Kernel: 2.6.32.9
Build: SPH-P100.EB28
