Possible to flash a Rogers modem on AT&T i747? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I would like to know if its possible to flash a Rogers modem on my AT&T GSIII so that I could turn LTE off and use HSPA+. I am running an AOKP rom which has the network mode option, it just doesn't work.
Would I mess up my IMEI number doing this? Thanks

You will not get any service if you flash an i-747m modem. Canadian users have temporarily lost imei numbers from flashing american modems.

Really? So Canadians who flashed AT&T i747 modems lost their iMEI numbers? Wow. Does that mean I'd loose mine too? What about a Telus modem? I just want the ability to turn LTE off.
EDIT: I just read through the other thread. That sucks that us AT&T folks can't flash Canadian modems. My next question is how does one unlock the AT&T modem so one can turn LTE off? Its rat locked.

you'd probably lose your imei if you flashed ANY Canadian modem. And plus Canada only has 2 modems. Why wouldn't you try to find a different apn for your carrier or settings> more settings> mobile networks> network mode?

AT&T is apparently shutting down its non LTE apns. I've googled many and none give me data, except the default one. This is on several roms. I hate AT&T for doing this. Why can't we shut LTE OFF. UGH

SGH-I747M from Telus

Ok, so yesterday i bought a SG3 from Telus(Im from New-Brunswick Canada, so its Telus, Bell or Rogers)... but the thing is i dont know if the kernels/recovery and roms in this section works for that model of SG3, its a SGH-I747M.... so i was wondering, if anyone knows about the hardware? Is it similar to the one from AT&T, Verizon etc? can i use the same roots/recovery/kernels etc? Thanks
Att telus same hardware different software. Interchangeable yes

Thanks you! so that means i can use all the firmware stuff the AT&T phone uses right?
It should work. I haven't flashed any custom roms yet, but rooting works with the ODIN/CWM/Root method. I don't believe we can use the no-flash counter method since ODIN should refuse to flash that firmware to our devices (based on previous experience with the S2 LTE/Skyrocket).
I just flashed a AT&T rom, it works fine, except it says at&t everywhere -.- now im looking for a more "universal" rom or something that isnt carrier related
Are you able to toggle off LTE? How is the cellular connection stability?

At&T version on Bell

I asked this question over on androidforums.com, but I did not receive a definitive answer. If I purchased a used At&T GS3, would I be able to use it with full LTE functionality on the Bell Canada network if I unlocked it?
Thanks.
I would imagine us they're the exact same phone both i747

Thanks. Can anyone confirm this?
Well you can use any unlocked phone on Bell. So basically it should work

No you can't. The LTE frequencies are different.

I can confirm that they are exactly the same hardware. You could flash the bell firmware from Samfirmware on the AT&T version, and it would be identical to what you get from a bell store here in canada. The LTE Frequency for AT&T is different, as another poster noted, but the Radio firmware for Bell would make it work.

No they aren't.. same thing.. you can flash a AT&T modem on a Bell phone, hence, the same.
I am running the latest att firmware on my bell phone so no issues

[Q] Rogers S3 on Bell network?

I just did a quick search, and couldn't find the exact answer (probably not using the right search terms).
If I got a Rogers S3, what needs to be done for it work on the Bell network?

You'll need to unlock the network first.

Rogers to Bell s3
Once unlocked, download selfserve and also make sure you have a Bell LTE MicroSim.
Than happy rooting or whichever way you decide to go!
Root. Unlock. Lte sim. Lte data plan. Lte provisioning.
I have the same thing. Rogers s3 on bell/virgin. Tho I an having issues with Lte but I think its a tower in my area.

wow you made that sound difficult could have just left it at unlock network and been done with it! You don't have to root first either.

No you don't have to root lol just unlock.
But for Lte to work you need to make sure you have you correct data plan, sim card and provisioning.

I can't say anything scientific or definite, but I just did this last night. I flashed the latest tmobile radio and the Novella Dos AT&T rom and it just worked.
Don't think so they are on different frequency

Really? If you did thats very interesting... maybe the new radio and rom opened the phone to at&ts lte bands.

I intially tried the ATT radio but it bootlooped. So I know for sure it was a the Tmo radio

Do you have a link for the radio? I would like to flash it because my t889 wont get a 4g lte signal either.
You think it would work without the at&t rom?
This may be of help for you guys. It was designed to use att phone on tmo, but it's a combined mod in that it enables att bands on our phone

Based on the tmobile jedix thread disccusion, looks like I must install the att modem to enable lte ontop of my normal tmobile rom

I think more than that, you have to enable the ATT LTE bands on the radio itself... that is a change made in the radio itself that doesn't change if you flash ROMs or whatever... ATT and T-Mobile use different frequency bands, so this may be all that you need to change... If you search here, I know I came across a thread about enabling those ATT bands... I don't have a T-Mobile Note2, so I didn't bookmark it... but I know it's on here...
Good luck,
Don

You can NOT cross flash modems. With ANY Device!!!. You'll end up with a lot of PROBLEMS.:banghead: Or even a brick!!
What you need to do is the AWS bands unlock feature!
Check here for what you need. Hope that helped you with your PROBLEMS!

Any galaxy s phone can use modem.bin or mdm.bin from any other galaxy s phone. As long as they are not sprint or verizon.
When did this change?

Well I haven't done anything like that. Don't think TMO GN2 modem will work well on a AT&T GN2... you'll end up with boot loops!!
Try it and let me know you out come.
I understand about the Verizon/Sprint.
