Now I have a potential warranty issue, so I'd like to try to revert everything. Since it's still running stock, I only need to remove CWM.
I found @bhsiddharth's guide to unrooting, but of course I need to get hold of the original bootloader.
The phone reports that its baseband version is I9082XXAMA9, and I'm in Australia. I haven't been able to find this bootloader anywhere, including these forums.
Can anyone point me in the right direction to find it?
