How do I downgrade the ROM? - AT&T Samsung Galaxy Note II

Hey XDAdevelopers forum!
I need your guy's assisstance in trying to unlock my Note 2, Canadian Rogers. (I317M.)
Looking around the forums and doing searching, I've managed to download the ROGERS MODEM I317MVLALJ2, and looking at the thread for everything Note 2 AT&T I've also seen the Rogers Stock 4.1.1 firmware.
I'm trying to unlock my phone right now, but I don't want to call rogers and pay their absurd $50 fee or use a website like cellunlocker.net for something I can do for free.
So this is what I need your help with. I have the original 4.1.1 rogers firmware downloaded, and I have the modem, but I don't know what to do with them.
I'm rooted with a 4.4.2 ROM right now, and from looking around some have said that I can just use the modem and unlock my phone that way, without having to change my current ROM. This would be the ideal situation but I don't think it's possible for me to do.
The other option is to use the Rogers I317 firmware, which should work on my I317M (don't know the difference), and flash it on CWRP recovery and then use this method to unlock.
The original rogers firmware includes a "SS_DL" file and a "KIES_HOME_I317UCALJ2_I317ATTALJ2_215287_REV04_user_low_ship.tar.md5" file.
The modem includes a META-INF folder, and a modem.bin file. I have no idea on what to do with these files to be able to unlock my phone, and I need your guy's help.
Thanks!!

[Q] Is there a way to root using a different carrier's stock image?

I have the Samsung Galaxy S3 (T-Mobile) and it includes all the unneccesary carrier bloatware. Since I'm not a T-Mobile customer, I would prefer not to have all the extra T-Mobile applications, so I was wondering when rooting with Odin 3, instead of using T-Mobiles stock image, can I possibly use a different carriers, like WIND Mobile.
The instructions I got were from:
http://forum.xda-developers.com/show....php?t=1771687
When I tried using the WIND image on my T-Mobile device, rooting fails!
Any suggestions?

Never use another carrier's ROM unless it specifically states it will work with another carrier. What you need to do is root with the official T-Mobile image that has root/super user injected into it.
Once you are done with that, get Titanium Backup free version from the market and uninstall what you don't want.
Use this thread which is in the Android Development forum for T-Mo: http://forum.xda-developers.com/showthread.php?t=1949687
That is the thread I started with when I rooted my T-Mo S3.
Technically what you're trying to do can be done. As said above, you shouldnt flash another carriers rom as the bootloaders and modem would most likely brick if the flash was successful(although i think odin checks this and the flash would fail anyway).
That said the system+kernel alone would be ok to flash. I actually have a package made just for this purpose posted here. See if that does what you want. Only thing is it was made for someone on moblicity although from what i remember the system was the same for both wind and moblicity(no branding or carrier specific apps). I can do this with WIND if need be just shoot a PM.

[Q] Help install Stock Rom issue via Odin

Hi there!
I have a Galaxy S3 SGH T999 version. It has Tmobile rom, but I am trying to install windmobile stock rom via odin (3.07 - tried other older versions) and it fails the secure check.
Is there way to resolve this? I really want to install the stock windmoile rom , and did lot of searching and couldn't really find a lot of info, except that someone with AT&T galaxy S3 had same issue when installing Rogers rom.
I would really appreciate it, thank you!

If you continue trying to ODIN flash firmware which is not intended for your specific phone
you will end up with a nice shiny brick sooner or later, in your case it will be sooner.
If you want the appearance of a windows phone, the best way to do it is to find themes and
launchers which make the phone look like a winmobile phone.
There are a lot of themes and launchers at the play store which do exactly what you are looking for.
Check it out B4 it's too late..
It's not a windows phone style, I think you misunderstood me.
I just don't like T-mobile rom and its bloatware. The windmobile rom is more clean.
Both phones models are same, exact. I don't see how it would be bricked. It's just a mismatch of bootloader, thus secure check fails. I've seen people with windmobile SGH T999V flash T-mobile rom, and it works perfectly.
It's just SGH T999 tmobile version isn't able to install SGH T999V (windmobile, mobilicity) canadian variant roms because of some block T-mobile setup. Some people had done this, but didn't specificy how though.
I would like to know that please.
If you don't like bloat, then remove it. Don't flash another carrier's rom.

UK modem file

Good morning all,
I have a galaxy note 2 7105
well i have been reading the pages on here for a few days and i have managed to root my device but now i am looking to unlock the sim, i have seen the free version of the *#197 etc etc and select the option for sha256 and initialzie but i dont get the 4th option to do that due to being on 4.1.2. i have seen lots of threads on here saying to downgrade my baseband and then unlock using this method and then upgrade again. now here is my problem, i can find lots of 4.1.2 modem files but no 4.1.1 which i was i am told i need, i have used other countries modem file but these did not get the options i needed to unlock my sim. can anyone point me in the right direction of either a custom rom with 4.1.1 baseband for the UK or a modem file for the UK that i can use to unlock and then upgrade to the stock 4.1.2. i am currently downloading the stock 4.1.2 modem from samsmobile.
any help in this would be fantastic.

Rogers Note 2 ~ SGH-I317M unlocked...

Since I can not reply to the genius post - "[REF] Your One-Stop Shop for the Note II (Kernels, Roms, Guides, Modems, Etc.)",
thread#:1987541 --> http://forum.xda-developers.com/showthread.php?t=1987541
I will post here, in case some one needs it
Rogers Note 2 ~ SGH-I317M ~ Android: 4.1.2 ~ ROM: I317MVLBMA3
===============================
I rooted my Note years ago using CFRoot.
To flash ROM, please follow the youtube video:
https://www.youtube.com/watch?v=KVrhNO__9JY
using all the files from thread: 1987541
files you might need: Kies 2 + ODIN3.07 + TWRP + ROM zip files
///////////////////////////////////////
Tricky thing: the latest TWRP from Google Play won't work on my phone,
so I used ODIN 3.07 to install open recovery TWRP , also used an old version of TWRP 2.7.1.0 ,
download this file - > twrp-2.7.1.0-t0ltecan.img.tar 7.5M
from link:
https://dl.twrp.me/t0ltecan/
After successfully installed TWRP, things will be easier, follow the video using Rogers Modem/Radios zip files
to flash ROM downgrade to: I317MVLALJ2
///////////////////////
You also need to install Kies from Samsung to make ODIN work, which is mentioned in the original thread.
If you use a PC, make sure you use USB com port on the back, not the front ones.
Would it not be easier just to flash stock 4.1.1 from sammobile.com using Odin if the phone is running stock 4.1.2? After unlocking, odin can be used to flash to the latest 4.4.2 or, since the phone is on stock 4.1.1, ota updates would work too but takes a lot longer to get to the latest rom.
I had a i317m on Koodo with stock 4.4.2. I recall flashing stock 4.1.1 which tripped Knox but allowed me to unlock the phone for free. This was about a year ago.
4.1.1 MODEM
Old thread I know but I am not having any luck finding the 4.1.1 modem (Rogers?) for the note 2 SGH-I317M .Updato doesnt have it ,nor sammobile, anything else I came across was very slow downloading and never finishes or were links that lead to unrelated sites. I want to unlock it for free if at all possible but finding this modem is proving to be impossible.If anyone knows where I can download or anyone can provide it that would be great.
Doesn't matter whether the modem comes from the stock Rogers, Bell or Telus ROM on sammobile.com. You need the LJ2: https://www.sammobile.com/firmwares/galaxy-note-/SGH-I317M/BMC/download/I317MVLALJ2/8189/
Now I see why I couldnt find it on sammobile.Only for premium users.I guess forking over 10 bucks to get it unlocked would be a bit cheaper.I suspected any 4.1.1 modem would do but thanks for comfirming that.All this unlocking crap is supposed to come to an end by years end anyhow in Canada.Locking phones will no longer be legal after that here and supposedly any that are locked are supposed to be unlocked for free. Cant wait to see what the carriers will try to pull.
There is no need to pay to download. It's slow, but free. I have a free account and I am able to download.
I feel dumb for asking but how do I download the file. Ive got the free subscription but it still says that its only available for premium?
Are you trying to downgrade an sgh-i317m from Rogers, Telus, or Bell?
LJ2 modem is here: https://forum.xda-developers.com/showpost.php?p=67958065&postcount=8
There is no free download for the LJ2 ROM.
No I was trying to downgrade from AT&T 4.4.2 to unlock my SIM but soft bricked it.
Ohhhh man Im so freekin happy. I finaly got my hands on the 4.4.2 file and got it back to its original state.
I still dont have sim access. Any ideas on how to do that via a root maybe?
What do you mean by sim access? Do you mean the phone doesn't recognise any sim card when inserted?
Companies in the US lock their phones to use only their SIMs. When I boot the phone, there is a prompt to give a code to use my local SIM here.
Oh, you mean the phone is asking for the network unlock code to use a non-usa sim? If yes, you will have to either request and unlock code from the original carrier or buy an unlock code.
This thread is about the sgh-i317m which can be unlocked using software. If the phone is an sgh-i317 and it is not running 4.1.1, you'll have to unlock using a code.

SGH-M919N Domestic SIM Unlock?

I've been seeing many other threads being created about this sort of topic and none of them really came to be useful in my sort of situation. I'm in a need of seeking help from anyone that could help me domestically (not internationally) perm. unlock my S4 without anything coming out of my pocket. The thing is, the S4 is locked towards MetroPCS and i'm unsure if T-Mobile will let me since both company's are considered to be one, but the phone is originally from Metro and not them, so I doubt they'll do it, I also doubt MetroPCS will let me either since I haven't had service directly with them for over a year, and this phone is extremely old. Any advice will be appreciated.
Which ROM is on the phone?
The only free method that may work would be to replace the phone's current modem to the 4.2.2 modem, root, run regionlockaway, flash back to the phone's current modem.

That seems useful actually, will try as soon as possible. Also i'm on the stock 4.4.4 ROM, so things should run more better. Thanks for the help
Edit: I haven't had any luck to grab the 4.2.2 modem and fw from any other providers. Do you know anywhere I could get the modem off of? Thanks
