Default [Solved] Unlock SGH-I317M Galaxy Note 2

My Note 2 is SGH-I317M (Canadian) locked into Bell Mobility. I tried the method described here but it as some people mentioned the option number 4 never show up.

- Should I downgrade the baseband firmware to 4.1.1 ? How can I do that?
- How can I backup my original baseband, so that after unlock I can put this back? (Ideally, I want the phone to be as much as close to stock as possible).

I would appreciate if someone can guide me into right direction. Thanks.

Baseband version: I317MVLUCMK5

I solved it and now have an amazing unlocked phone.

For future reference:

- Use TWRP to backup your modem
- Download ROGERS_MODEM_I317MVLALJ2.zip (Modem firmware from Android 4.1.1) from http://d-h.st/rJq
- Go to TWRP and install this zip
- Unlock
- Restore newer modem back using TWRP

For me, Odin failed!
Note II Variant: SGH-I317M

The J2 modem is all anyone needs to flash. I also had to go through a couple different files until I found a flashable zip that worked.

Will reverting to that J2 modem work if you are already at at 4.4.2 based ROM on the note?

So this allows us who are on android 4.3 to flash back to android 4.1.1 and unlock the phone via the hidden menu? How do you actually backup the baseband of the phone. When i last tried to flash a 4.1.1 stock firmware over my rooted note 2 running android 4.3, it said failed and wouldn't even load into recovery!
