Roms, radios and whatnot - AT&T Samsung Galaxy Note I717

OK I have been all over these forums and the T-Mobile forums and I am not 100% crystal clear. I know that you can use the T-Mobile ROMs but how come you need special radios if you use the stock T-Mobile ROM. I had tried to install the actual Tmobile modem but it slowed down my phone so much that it wouldn't work properly. So I guess my question is how come if both unit are the same why cant they use the exact modems and have the exact effects. From what I understand the modems we use have to be kinda tweaked. I am sorry if this seems to be an ignorant question but this is my first device since the HTC Raphael that I have used a phone that was not branded for my carrier..........

[Q] I want ROM for Atrix from Bell

Hi guys
I have Atrix 4g from Bell Canada which rom should I used with it.
Thanks
There isn't one right now available right now unfortunately...
You can factory reset to get back to stock
Sent from my MB860 using XDA App
the problem is that if ANYTHING goes wrong while developing the ROM, causing a soft brick (which can be done by loads of things, and is almost guaranteed to happen during development), there is no easy way (realistically no way at all), to recover from it. we have to wait until a retail .sbf gets leaked or released from bell before any real development using the system files can occur. Anyways, ROMs for the Atrix aren't really ROMs in the true sense of the words, merely heavy edits to the themes and cleaning up some bloatware.
In the meantime i recommend you go here, here, and here for now, those are the main things that can be done for Bell Atrix at the moment. make sure you read those threads thoroughly and understand what you're doing before you do it though.
Thanks guys
Is there any update about rom for Bell devices ?
There is a generic rom u can flash have a search around for it

[Q] How do I update radios

I have searched and have not found enough information to make me confident so my question is, how do I update my radios and such that just came out a few days ago? I am running synergys newest rom if that makes a difference and I want to see if these new radios will improve anything.
What's wrong with your device? If nothing don't mess with radios.
If it ain't broke don't fix it

pretty sure everything you need is in the radio thread.
also in the stock rooted thread there is a link to radio/pri update in one.
not sure why spastic doesn't like to flash radios... don't worry it's not a big deal although if you can't read around enough to find this info maybe you shouldn't be doing it

Japanese photon from au

Anyone know if any of the custom roms for the 4g will work on my model? Thx in advance
Sent from my SAMSUNG-SGH-I777
It's a Photon correct?
Edit...
So after thinking about it I would be kinda careful. If it is a Photon, I don't see why it would be an issue, but I remember reading people having issues flashing custom ROM's for the Galaxy S II (The unlocked version) onto their Sprint/AT&T phones and it screwing things up. So that's something to think about. It was mostly radio issues and such, so I think you should be fine, and if not, you can always RSD back to a stock build.
Ok thx
Sent from my SAMSUNG-SGH-I777
As I said though, just be careful.
Also, just for ****s and grins, I'm going to sleep shortly, but check what build you're on, it should be either 154_7 (I think) or 198_6/198_7.
the build number is 4.5.1a-1_kdi-92_le-24
I think that's a different build number
I wonder if we had a full dump from a unlocked photon if that could help with dev
Sent from my MB855 using XDA App
That is a different build. So I am not sure how it would play with it.

[Q] Does flashing back to stock affect T-mobile modem?

I've flashed a T-mobile modem and using with the HSPA+ for awhile, however the Saurom ROM I'm using has some bugs like I can't reboot my phone properly and I sometimes lost signals, so my question is: if I want to flash my Note back to stock android, am I gonna lose the capability of using the HSPA+ which I'm using right now? Is there any ROM you would recommend that would be stable for the Note and still have the T-mobile modem enabled? Please give me an answer because I've been confused with this for awhile. God bless you all...
Question
Anybody? Please?
I'm using Saurom 7.1 and ICS theme on,Blaze modem and its been running great. It isn't as fast speedwise compared to my Amaze 4g but stable and fast.

You will probably have to reflash the tmo modem. But it might still be there as others have had non-stock modems that were still there even after flashing a stock tar file.

Best way to be sure would be to flash the stock radio. Though, it would be nice to know if using Odin will put EVERYTHING back to stock.
I'll bet the answer exists on the forum already but it's a good question, regardless.

Oops. Read the question wrong. So far as i know, once you flash a radio, it's there forever. Unless you flash a new one. Depending on how someone makes their ROM, this could change, but I'm betting that most of the devs aren't worried about forcibly making the people flashing their **** switch modems.

Yes you will. I noticed that when i installed the at&t stock Rom

thanks for sharing. I've heard some infos about flashing back to stock could affect the radio, but I feel relieved when I saw this.
Dont worry about the modem in GB just flash it and it'll work
all ive heard is that the "ICS leak" doesnt play well with TMO modem
but idk to be honest

Two quick rooting questions

I'm going to root my friends GSII and have a few questions. I'm experienced with rooting since I've been flashing roms/kernels since my old Evo 4G and my current Evo 3D, but I am unfamiliar with Samsung phones. I've read the stickies but still was unsure about a few things.
What exactly is odin and what does it do? You can flash a rom/kernel normally through recovery right?
And last one, what is a modem? Is that like a firmware package that we have for HTC phones?
If you're going to do this you have to read around. Google will help you out big time
Sent from my SGH-I777 using Tapatalk 2 Beta-5
I have read around...I read everything for the rooting process as well. After everything I read, I have only those two simple questions. Is it really that much of a pain in the ass to just answer them? Whatever happened to a helpful XDA community?
I'm only saying this so you know how to do some troubleshooting if something goes wrong. If you Google "samsung modem vs HTC radio"or something it Will yield results. Also searching for Odin on wikipedia I know will yield results. This is xda, a developer site. You're supposed to search before posting whether it be Google or here because chances are people have asked the question before

For rooting or obtaining root access, I believe there are 4 options, all listed on the FAQ. It's your choice. For simplicity, I chose the first option.
Modem? Like radio, quality of call (?), quality of data (?)
Don't have enough technical knowledge to clearly explain to you, m8
To rest your case, rooting is easy.
Relax.

Odin is a proprietary software made by Samsung that runs on the Windows platform and is used to transfer firmware onto a samsung phone. You can flash firmware through ClockworkMod Recovery, which is built into the kernel portion of the firmware, but you cannot flash firmware from a stock kernel, you must first install a custom kernel which has CWM Recovery built in.
And last one, what is a modem? Is that like a firmware package that we have for HTC phones?

I'm not familiar with htc phones. Modem is like a radio on other phones. It is a separate piece of firmware that can be flashed separately, or along with other parts of the firmware, which handles the cell network interface, wifi and some other things.

Radios in HTC phones can't be included within roms, only RIL's can (RIL is software that matches up with the radio I believe).

i havent installed any modems yet. but i did change the apns that are in the aokp faq. it put me back to dload speeds of 6-8Mbps vs the 500kb - 1Mb i have been getting through att since october and the stock apns provided in the aokp rom. the modem itself i believe is included in the aokp rom.
i doubt any of that makes sense to you... but i tried.
and yes... some of the people around here would rather take more time to explain to you why they arent going to give you the info u need rather than just telling ya. i think it makes them feel superior. but hey... who am i to complain... they bust their asses to make the roms for us.

Aokp doesn't include a modem
I couldn't easily help him from my phone, he could have easily found this information though. It's not about the superior.
