how do you change w580i back to original state?

i have unbrand/flash my w580i just yesterday
but i heard ur warranty will be void unless you change it back to the way it was
im using rogers at&t's w580i
can someone tell me how to do so, and what are the files required?
thx in advance :)

You need to flash branded firmware to your phone, AT&T in your case. That's all

i too want to do this?

Just buy another credit at Wotan, and flash it back if you have to. Thats what I did.

You don't need to pay wotan for that operation. XS++ or SE Tool lite can flash it for free.

where can I find the original AT&T firmeware...does anyone know? thanks for your time ahead of time!

I don't know, haven't seen them yet, either. You could try a SEUS update. It should detect your phone as a AT&T phone and brand it.

Try an update with SEUS

EDIT: Networks would never probably know that anything has changed if you needed to have it repaired anyway

ahh ya i think using SEUS will do the trick :) thx alot

why would you want to make w580 to w910?

You must backup your phone first before you debrand.

If you want to get the original firmware, you restore backup.

where do i dl SEUS
