Please help! Have spent hours trying to get this to work. Bought a used SCH-I800 tab that was rooted and I can't seem to get it back to pure stock to where it will take the MC2 OTA update!
Have read and read and read and following instruction exactly, but no go! Tried to Heimdall many stock rooted ROM images then unroot using SuperOneClick. It appears to unroot properly,
but still fails to take the OTA update (fails at around 25% after reboot and goes to triangle warning screen). Anybody have a pure stock unrooted Heimdall image they would share? Or please
tell me how to fix it another way? Tried a couple images that were supposed to be stock, but resulted in boot loop (errors mounting read-only file system on recovery screen).

Thanks in advance!
