Did a hard reset on my Tab just now just for the purpose to see how fast it reboot - not long ; took about 8 minutes to fully boot back
Unlike the Samsung Galaxy S - hard reset will not erase/delete any contents of the internal SD card . This is very good feature , meaning all your supporting data/files/backups which are installed in the internal card remains intact.

Will later try to install a clockwork recovery or a modified kernel with CR so that I can do a nandroid backup. This will be very useful if you want to flash roms and if you don't like the new rom, you can restore everything ( all apps/data etc) exactly back to your last status

Anyone here had done any Clockwork recovery Mod - will appreciate some tips. Spend an hour reading through forum XDA on all the possible ways and user's failures/recommendations ; hope I can do a successful one try

Next step will be to flash a new firmware than only flash a new 3rd party rom

After you flash rotohammer rom, did you install a ClockworkMod Recovery ? If not, you can try Chainfire CF-Root which is compatible with rotohammer rom
