Device Information - ExtROM version unavaible

[Surfing]

Please help...

I've been upgrading and downgrading from WM5 to 2003, respectively. I've also upgraded my ROM version to 1.13.00.

I'm looking under Device Information and it shows:

ROM version: 1.40.00 WWE
ROM date: 03/10/05
Radio version: 1.13.00
Protocol version: 1337.42
ExtROM version: (blank)

I'm not sure why my ExtROM is missing if I missed a step while going back and forth from different windows mobile versions.

Please help. Thank you.

you should have a ms_.nbf file in your upgrade dir, if not then you won't get the extended rom

take care the 10th step, you should set the size for Extended ROM as 16348 (to copy file ms_.nbf later)

follow and finish this step (included A and B).

Have fun!!!
