How to revert back to original ROM?

[Guest jcvendetta]

I have upgrade into Sector's latest ROM. and now, for my phone is faulty and I need to send it back for warranty purpose, and they wont accept the phone if its installed with custom ROM!

I tried to revert back to the original ROM from the Samsung website but it says " you have the latest version of ROM" and it wont let me install it! Please teach me how to revert/ downgrade back to the original ROM. Thank you very much

There's no way to revert back to your old ROM unless you have a backup of that ROM, or get a copy of that ROM somewhere else.

You can install an official ROM from Samsung website though. Download the ROM for your country...

Then go here http://www.modaco.com/content/i900-general...rsion-tutorial/

Read that tutorial to tell you first how to change your phones country code (with a custom ROM you most likely have the incorrect country code) then follow the tutorial to flash to that official ROM.

Hope that helps.
