Hi, my girlfriend has a note 2 that was originally from rogers, she has gone over to bell and i was wondering would it be possible to flash the stock bell firmware on her rogers phone or would this end up with some type of damaging effect. any help would be great. her phone is the sgh-i317m
Really, the only difference between the roms is the carrier's apps. Changing roms doesn't improve connections.
What app is she missing? Or what does she hope for by changing? I always go out of my way to remove any carrier branded apps!
There's no advantage to running the bell firmware over the Rogers. Unless you need the bell apps, but those are on the play store anyway.

I find the rogers modem better than bell one
Sent from my SGH-I317M using xda app-developers app
The firmware is the same, and so is the modem. What differs between the two is the CSC, carrier specific content. You'd have to check if Fast Dormancy and HD Voice still work, but those are about the only two tweaks that changing CSC might affect.
I don't know for sure about fast dormancy, but HD Voice required a factory reset to activate in some circumstances.
There is a code to change the CSC from another already available on the phone, but I don't remember it off the top of my head (it's been posted on here a few times already). Caution, it does wipe the phone without warning.

If the phone already rooted you don't need to flash firmware again to get Bell's rom. Just go to playstore and install the app from link below. All ypu need to do is change CSC thats all.

Cool thanks I appreciate everyone's help, The main thing i was worried about was flashing different radios and messing that up but since i can just install the bell apps from the play store i see no reason to really mess around with it. thanks
Right. All North American carriers use the latest modem.
POSTED IN ANY QUESTION THREAD - CAN DELETE THIS AND PLEASE REPLY TO MY Q THERE THANKS - SAME Q JUST FIGURED EASIER TO POST IT THERE
Have a stock non-unlocked (no unlock) at&t phone with 4.2 android.
Could I use the 4.3 "no-knox" modem.bin I see in these forums that's for t-mobile and just ODIN it over top of the at&t 4.2 modem (mdl modem for at&t that came on the phone when it was purchased) and then use CWM to install a t-mobile rom and have the phone work under t-mobile?

Just because someone else is going to find this thread and start getting ideas...
NO!!!!
No one should EVER do this. Never flash a modem that was not SPECIFICALLY made for your SPECIFIC device.

Ok so tell me please what you mean? Do you mean specific device hardware or ???
Because the only difference I see in the 2 phones, At&t S4 and T-Mobile S4 is all in the software for modem and rom. They are 100% identicle in hardware, even being factory set for bands both carriers use. I would never attempt this on Verizon or Sprint S$'s lol - but I am cinfused other than a different modem bin file and different rom, and different model number since its 2 diff companies, what is the difference?
I am confused.
If I cannot do what I noted, then how does one use an at&t phone on a t-mobile network? I am great at flashing modems, roms, recoveries - but my 1st time switching carriers on an exact same model phone. The phone itself is same model far as samsung makes it - only changes to different model when its branded at&t ot t-mobile and uses that companies rom and mode,m files. But isnt the hardware the exact same both places and couldn't the rom and modem files be swapped to allow it to work on the other one's system?
Please help what I need to do - if I cannot do what I asked about then what?

If the two phones ATT i337 and Tmobile M919 were as identical as you say they are and even use the same bands then
why is the gsm baseband (modem.bin) and the lte modem (non-hlos.bin) different enough not to be interchangeable?
Not even the STOCK 4.3 firmware or any of the zipfile custom roms here in xda are not identical enough
so we would not need to have two different and separate forums for these two phones.
First thing you need to do is to get your phone on the Tmobile network is to unlock it or have it unlocked.
Then you need to get a tmobile sim card and root the phone if it's not already rooted.
You will also need to flash cf-autoroot to root the phone and then flash a custom recovery like cwm or twrp.
Then last but not least you will need to flash a Tmobile custom rom from the Tmobile M919 forum.
None of the custom roms found here in xda contain modem.bin or hlos-bin images.
Those you already have in your phone will work fine even though they are NOT identical.
The two .bin images are setup so the two networks can establish GSM and LTE communications
between your phone and their towers using different bands and different frequencies.
Good luck.

Thanks Got her phone working ok. So the key was if unlocked, the at&t phone will work on t-mobile even with an at&t modem file on it I knew the 2 companies could be used on the other's network just did not know the modem file works both ways if unlocked. I assumed the hardware is the same on both phones so just flash a tmobile modem lol - I learned I was wrong thanks for ur help. Years of rooting and never had an issue with using one carrier on another carrier's network, was my 1st time
Thanks a lot for your help. Its working great now!
I have a boost mobile s3 and want to know weather its possible to flash it with a sprint s3 stock rom WITHOUT complications
the Baseband version is L710VPUBMK5
i have downloaded the sprint rom and want to confirm its safe before i go ahead
its fresh from box and not activated, all i want is to use the phone on another cdma network outside the USA

Try HERE. I suggest you read 1st couple of pages. I think JDSingle's ROMS on that thread are stock and have been modified for you. Also you will need root and modified recovery from HERE. If your wanting to use phone on a different carrier, your gonna have to unlock phone, totally different than changing roms, but you wil still need to be rooted and have custom recovery that I linked above. Read HERE for unlocking. ALSO Im not 100% sure this method will work as thread is for unlocking the Sprint version. Ask in that thread.
So I have am using already a T-Mobile S4 (m919) on At&t's network... I have already rooted it, flashed Hyperdrive, entered the correct APN, and it works basically well...
Here is what I am wondering, my signal strength seems to be not the best and it makes me wonder, is there a modem, baseband I can flash on the T-mobile version of the S4 that could possibly help it work better on the At&t network... and do so with out making my S4 a paper weight?

Glad someone asked that. I looked for a few hours last night and came up empty(been working an off shift so I might have missed it). I am on 4.2.2 MDL and signal is definitely much weaker than my Active on 4.3 . Has anyone compared modems to see which are better?

I can provide anecdotal evidence but nothing real...
MK2 is better.
Also, as for which modem to flash; T-Mobile's MK2 would be the one to flash. I've read you can flash other carrier's modems as long as they are the same version, i.e. AT&T MK2 or T-Mobile MK2... but that just doesn't make sense to me and I wouldn't recommend it. The modem you flash is independent of who your carrier is; you go by what brand of phone you have. If you have the M919 then you flash T-Mobile firmwares/modems/etc regardless of which carrier your bill comes from.

I've encountered the same thing with my M919. Switching between Android 4.3 and 4.4.2 modem.bin files made no difference.
I did notice that when I changed my network preference from 3G/2G to 2G-only, I gained about 10 dBa when the handset fell back to GSM-EDGE mode. It made a big difference. I verified that AT&T only uses band II (1900MHz) for GSM and UMTS in my county, so it wasn't because I switched to band V (850MHz) which seems to have better range. What I find annoying is that the handset isn't dropping down to 2G automatically when reception is poor. It'll stick with 3G even when the signal strength is as low as -107 dBa.
No LTE at the moment since my AT&T MNVO doesn't support it.
I'm thinking of buying an M919, carrier unlocked, to use on ATT, so that I can get a proper recovery and have full access to custom ROMs without the safestrap limitations.
Is it safe to say that:
1. If I buy a T-Mobile S4, and it comes carrier unlocked, it will work fine on the ATT network, including 4G / LTE? Lots of data points suggest this but I haven't heard it explicitly stated...
2. Though I could use the phone as identified as an M919, I really want Play Store to see it as an I337 (ATT version), so I can install some ATT specific apps. Is there any problem flashing a build.prop (available in the ATT threads) with the ATT identifiers & APN info, to enable this?
3. Are there any gotchas I should be aware of? Basically, I just want a phone with unlocked bootloader / kernel so I can play. Not too worried about Knox/warranty.
Any insights would be appreciated!

Will the T-Mobile S4 work on the AT&T network; yes it will work if it's carrier unlocked. I purchased my M919 full price out of contract while I was still on AT&T service. Once I carrier-unlocked I was able to pick up AT&T's 4G/LTE and was even able to make use of the AT&T 3G Microcell device which transmits a 3G cell signal and runs over your WiFi. I now have Net10 Wireless with an AT&T SIM card and I still get 4G/LTE when it's around.
Your second question: I do believe that's all that would be required. I'm not 100% sure if just modifying the build.prop would allow you to use the AT&T-specific apps in the Play Store. I never used them to begin with so I never explored whether or not I could make them work on the T-Mobile firmware. Now, I know this involves more than just a build.prop edit, but a 100% sure way to get AT&T Apps working would be to flash a custom ROM based on AT&T firmware. Being that you have a T-Mobile device and are using it on another carrier's network, always remember; when it comes to Odin especially, flash things meant for the T-Mobile M919 ONLY. It doesn't matter that you use AT&T service, your device needs T-Mobile Modems/stock firmwares/etc.
As far as gotchas... not that I can think of. The M919 has an unlocked bootloader and even with KNOX is very easy to root and use custom ROMS on. If you're not concerned with KNOX then you really don't have to take into consideration any special rooting method, no safestrap junk, etc. Without root, just flash a recovery in Odin and flash away.
I know this thread is a bit old, but the situation is very relevant to me. I just won a S4 M919 on eBay which will be delivered tomorrow. T-mobile has agreed to send me an unlock code. My motivation is to install TWRP recovery which I can't do on the i337. I intend to activate it on Cricket (AT&T network). Is it still true that I should stick with firmware, ROMs, and modems designed for the M919? I don't care about AT&T or T-mobile apps so that's not an issue. Basically, I want the best data rates available. Any gotchas that I need to be aware of?

Basically, you're best off bringing the phone to current M919 stock through ODIN. Is that NK2 or has there been a more recent version? I've lost track. But do the entire phone, and in fact as you will see from some threads it is often necessary to flash it twice in succession to get everything to stick. This will bring you to the latest modem. Remember, the modem is two parts: the modem.bin (also known as the gsm modem, which isn't specifically dependent on the bootloader version you have) and the LTE modem (non-hlos.bin, which is dependent on the firmware version, and bad things happen if you mismatch).
Since your phone is out of warranty, there's no downside to going to the latest, even if the phone arrives with 4.2.2 firmware (pre-knox). Tripping the knox bit is only a problem if you would be sending the phone in for warranty service.
I've got the M919 and am using it on ATT, with no problems. I've got the pre-knox firmware (MDL), and will be updating to the latest next time I flash.
Here is an old, but still relevant, thread about my experiences with M919 on ATT.

You will have to configure your APN to match your Cricket service. Sorry, can't help you with those settings but I'm sure they are on XDA somewhere!

Thanks a lot for that update. As I understand it, the current firmware is NB4 according to this site:
http://galaxys4root.com/galaxy-s4-stock-firmware/
Not sure what your reference to NK2 is? That doesn't seem to correspond to either 4.2.2 nor 4.4.2? I'm currently on Cricket with a S4 I337 and hope to move the SIM over as soon as my M919 arrives tomorrow.
I believe after NB4 there was NH7 then NK2. Check the firmware thread in the general section for details / links.

Robert417919,
I use my SGH-M919 on an AT&T network also. I use the OK3 modem firmware and it seems to work great here. Although I am in Alaska, so top speeds of LTE are only about 6 Mbps where I live. Usually I can only get about 3 Mbps due to the lack of coverage around here.
You can either update to the latest OH3 firmware on your phone, or if you have an old model, with the MDL bootloader, you could also use this guide by lordodin912:

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!!
