stuck on edge? - AT&T Samsung Galaxy Note I717

Hi all, I am considering purchasing an AT&T galaxy Note, but I use tmobile, If I nlock the phone, will I be able to use the 4g network on tmobile or will it be stuck on 2G Edge only?...Thanks in adavance.....Larry

Just buy a t-mobile version of the note. Avoid all the jerking around everyone does when they buy a phone for the wrong network.

That still doesn't answer the question..I can her a good deal on this phone

you could flash the blaze modem to get 4g on T-mobile but from what I hear is it can be unstable at times

Blaze modem use for running the SGHI717 on the T-Mobile network, will give you marginal performance, with the risk of damage to the device.
1 in 10 users have suffered device sim detection failure when running this device on the tmo network.
The cause for this failure has not been identified...but if the problem occurs, the device will be rendered unusable.
Your question did get answered, as a senior member did advise you to avoid the risk by using a device designed for your network, and I agree with his recommendation.
Buyer beware....g

Its not a good deal if it sux to use. Its possible to get 4g but as ^^^ said it's pretty rough.
Do you really want to hear the daily complaints about dropped data/slow data from your sweetie? Money doesn't matter--wife/girlfriend happiness matters.

[Q] Question About Atrix's bandwidth

I hate AT&T but I do like the Atrix. If I manage to unlock it, I know I will be able to connect to T-Mobile's edge network, but is there any chance it would be able to connect to T-Mobile's 3G and 4G networks? Before anyone says no out of hand remember an unlocked Vibrant can connect to AT&T's 3G network.
I know this seems like a dumb question but I really do hate AT&T and would rather stick with my Nexus S on T-Mobile than use an Atrix on AT&T. So I'm hoping that the unlikely possibilty exists that I can use the Atrix on T-Mobile's network.

Short answer...NO.
I was afraid that would be the answer, but out of curiosity you said the short answer was no, is there a long answer that is yes?

lol, you don't give up do you? Well it's still no. This phone was not built with AWS bands in mind, which are 1700/2100mhz. In case of the Vibrant, I guess Samsung wanted more world support and offer the 1900mhz which is also supported by AT&T. Either way you take it, it's just not going work.
I suggest you wait for now, your Nexus S will keep you happy until T-Mobile gets some dual core love as well. Just try and be patient, sometimes this pays off in the end ..
Besides, you have more dev support right now, so go flash some ROMs.
Thanks, for taking the time to answer my question with such great detail. I will stick with my Nexus S for sure now. I knew it was a longshot when I posted but a guy can hope.

T-MOBILE note users...information needed !!!

T-mobile note users ....
I'm posting this thread as a request for information today.....let me explain.
Within the past few weeks, many members have reported sim card errors on their tmo devices after root and flash of custom roms.
I personally know about 5 devices within the week that have suffered this failure.....3 of which, have been recovered by downgrading to Gingerbread .....
I'm sure there are many more sim issues we haven't heard about, as they likely haven't posted.
My intent here, is to have as many tmo users as possible, post your flash success or failure, in an attempt to prevent more sim failure issues.
Although I'm an ATT note user, I'm willing to help monitor and collect data here, so future users won't suffer the same fate.
2 of these failed devices were sent for repair, even though they were only days old, and worked perfectly prior to root and flash.
So please, if you are using the T-mobile network........please post your history and results.
Together we will likely find the cause .
And perhaps generate enough attention to the issues, that a fix can be found...
I am not attempting to cause panic, but I feel we need to fix the problem now, before we have dozens of affected units, rather than just a few.
Many thanks in advance ....g

I would mention that many t-mobile subscribers cannot get good data and voice while using the at&t version of the note. With the choice of an at&t and a t-mobile model, you should get the t-mobile model -- you will be happier in the long run.
Happy T-mobile user

I bought an AT&T note off craigslist about a month ago. It was unlocked, before I handed over the cash I put my T-mobile sim in and called a friend he said it sounded great so I bought it. I did a couple of speed tests with it and usually get between 3 and 6 mbps down and a lot slower up. I've had no problems, everything works great including GPS. It's running ICS 4.04 stock AT&T ROM and the baseband is unknown. I don't know who unlocked and set it up but they did a great job as far as I'm concerned. YMMV
off-topic, deleted.
It's all good ranger ....
Any and all info on the T-Mobile network while using the ATT note is welcome ....even the success stories.
I did request both in the OP, as I feel that we need both sides of the user responses to nail this thing down.
I do appreciate your response, and ask you for any assistance you can provide here.
This problem is so odd .....as it's not a brick ....but yet it is ....g
I sold my note to a TMo user...called them today(two days after) and they said it was working amazing....it was rooted and unlocked by an amazingly awesome person though(haha jkjk). The guy never rooted before and said the speed tests were rocking his gfs GS3 in TMo and the clarity of the call was great as well....ait could be a root issue or ROM issue though...
As far as unlocking if the pgones unlocked any way except for calling ATT customer care there is always that risk...plus a three minute phone call and giving someone your imei shouldnt be too much hassle .. So theres that dudes exoeruence from someone that knows what they are doing(kind of)...
The rom I left him on was AOCP CP3 by the collective jsyk

noting the unlock method here.....
I believe you are right.....We have many service unlock options, but only one that is safe....and thats the carrier method...
could this be as simple as users not unlocking the sim prior to root and flash ??? or an improper unlock ???
I'm hoping we can get some users in here to clarify that possibility for us.
Many thanks for bringing that up....g

Users on the T-Mobile network, are losing the ability too see or access the sim card, after rooting and flashing the device with a custom rom.
Generally they are flashing ICS, but we also have some users reporting sim loss while using GB roms as well.
We know a few things that are leading to a possible cause.
The first is the carrier offset (my term for t-mobile users with an ATT device )
The second is the need for carrier unlock for the device to be used at all with t-mobile.
The third is the inability to restore "any " sim activity after the failure....(although a few users have been successful after a complete unroot and downgrade to GB .
Although I haven't yet found a pattern in this ....I have reason to believe we are seeing a carrier related lockout of some kind, as the sim functions fine in other devices, and the device functions normally minus it's ability to detect the sim or any network.
Perhaps a good next step, would be to re-lock the device to the carrier again, after a complete stock restore of the device.
I wish that we had an affected device to try this with, but unfortunately, the affected users are returning the device for repair or replacement.
Not all users will, as they need a working device immediately, and are trying desperately to restore functionality.
That being said, I'm hoping this thread will draw an affected user here, so we can explore more aggressive, and hopefully effective solutions.
I can't ask anyone to risk a device beyond their willingness to try, and with some proactive thoughts from our fantastic user base, we will crack this problem open, and create a fix.
We all know the risks involved in flashing firmware images, but since we are now crossing not only the root/flash barrier, we are adding the carrier change into the mix. And that brings it's own unique set of challenges to the table.
I sincerely appreciate any and all help, in my search to help our note users succeed in fixing the ghost in this machine ....g
I know this is a noob question but I've been reading all these t-mo service/I717 threads cuz I'm thinking of doing this. Does rooting the phone unlock it? I'm on the liquid jb rom.
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
I would like to echo what rangercaptain said earlier in the thread, regarding the fact that the SGH-I717 was never designed to run on the T-Mobile network.
And although we have virtually identical hardware and operational features, clearly something is different enough to cause this issue.
And I "do not " believe it is user error.
In the meantime, I would advise any user thinking about converting the ATT note to use on the T-Mobile network, to think very hard before attempting to do so......at least, until a verified and working solution can be found.
Ultimately, we need a bone stock ATT note, and a t-mobile user brave enough to try the process repeatedly, until the cause is identified, by eliminating one process at a time ...g

Rooting a device simply gives it's user the administrator rights needed to access the protected system and data sections of the device, that are normally reserved to the factory, carrier, and programming engineers of the software.
It does nothing to unlock you from your carrier.
That is done by contacting the carrier, and requesting that service.
It is also possible to be unlocked by a third party, but clearly their are risks involved in doing so while using the ATT note on the t-mobile network.
We are working very hard to correct the current "no sim card present" issue ...g

I have been running the AT&T i717 note on the T-Mo network since Tomin figured out how to get the 4g working, many months ago. I have not had problems with voice quality or sim card issues. I have run the Saurom GB roms, Goldie's Only1, many ICS roms, and now am on the stock T-Mo rom with the Blaze ICS modem.Tried all the modems, and Blaze works best for me. YMMV. I got a new sim from T-Mo to enable wifi calling. My data averages 3-5 megs, upload 1-1.8 megs, but at work I regularly hit 14 meg download. But like everyone, the speed is erratic, but functional for everything I do, including streaming netflix. My speeds were faster and more consistant with the GB roms, but the ICS speeds are plenty fast. I unlocked my phone with cellunlocker.com I think was the service. Nothing but a success story with my AT&T note on T-Mobile. And I get to keep my unlimited, unthrottled $5.99/month grandfathered data plan with 4g (if I used a "known" to T-Mo 4g phone I would have to upgrade. The AT&T note is "unknown" to T-Mo, If I got the T-Mo note it would trigger new data charges). For me, this is the point of the whole excersize. I have been lucky, and the Phoenix area has good coverage for me as far as T-Mo. This has been my experience.

[Q] AT&T Samsung Galaxy SII blocked IMEI help

Okay so I found a nice new phone come into my hands from a craiglist deal, popped in sim card, everything worked great. Sometime over night my device had been blocked from network use. I understand AT&T now can blacklist a phones IMEI phone and block any network access onto AT&T's gsm network. My sim would no longer work in my older phone, so I called and got that fixed, but I now have a stupid nice phone that im using for a paper weight. Obviously the person who sold it to me either knew it was reported lost or stolen, or reported it after selling it to me, its whatever it happens right. I dont want to go on craigslist and rip someone else off, thats not fair and would make me a ****ty person.
So I still have the phone, I know ill never be able to change IMEIs even with samsung tools12.7, and I know ill never see AT&Ts network work on the phone. Now, I understand that t-mobile is also on the gsm network, and I know that t-mobile has the highest block/blacklist capability of all cellphone carriers, that will even block an IMEI just for a late payment. But does AT&T share the same IMEI block list as T-mobile? Would I be able to just root my phone, and unlock it for Tmobile use, get a tmobile sim card and go from there? Or since theyre both gsm is my IMEI gonna blocked from all gsm networks.
I just need a way to put this phone to use, I spend good money on it and would like it to work. Even if that means switching cell phone companies and starting up a new "go phone" like plan. If anyone with any helpful tips or any useful information could just throw me some of their time with a reply I would be so grateful.

Report the buyer to ATT and they can unblock the phone if you can prove you bought it from someone.

It will operate on TMo, but except in a very few areas where TMo uses the same 3G bands as ATT, you will only get edge data speeds.
Edit: once it's unlocked it will operate on TMo.

Yup, T-Mobile and AT&T will be sharing their IMEI blacklists soon so it will only work on T-Mobile for a month before they start blocking it, too.
You can either use it as something other than a phone or sell it on eBay to someone who doesn't want t use it as a phone.
Or track the buyer and report it to ATT. They will remove it if you can provide proof.

[Q] Contemplating Switching From Sprint

Hello forum-goers! It seems that I am at a crossroad right now. I have been researching switching to T-mobile for the past few months now (I was sold on the Wi-Fi calling feature). I just had a few questions before doing so.
1) Would you guys recommend switching over to T-Mo now or should I wait for the new, new to to switch over (I haven't owned an HTC since the Touch Pro 2 and the One is a pretty sweet device).
2) Does anyone have the insurance/JUMP program, I am pretty clumsy with my phone so I have the insurance with Sprint on my current Samsung Galaxy S II? Would you recommend getting a different type of insurance (like SquareTrade)?
3) Does anyone have any experience using this device in the SF Bay Area? I have heard plenty of good news, but it's mostly in different states.
4) I was flashing ROMs on the Touch Pro 2 (Windows Mobile 6.x) and the E4GT is my first Android phone, what is the learning curve with HTC Android devices?
I don't have much to add but I will say WiFi calling is great to have considering T Mobile's poor building penetration. Sending and receiving text is not an issue but when having an actual phone conversation the other party can't hear you to a few seconds after you said it and the whole conversation sometimes become awkward and confusing deciding who needs to speak next, but its serves its purpose.
As far as the jump program goes its really not a bad idea as long as you get approve for no money down on the original headset or else it really makes jump seems like a bit of a rip off considering you could sell the phone yourself outright and not lose out on the initial deposit you made on the phone.

i just switched from sprint to T-Mobile and havent looked back once. was worth the 180 ETF. I really really wanted to stay with sprint but their service just kept getting worse and worse as they "upgraded" towers. I do have the jump program and i dont see why you want to use a different insurance. its ten bucks for full insurance (sprint was 11 or 12 now i think) plus it allows you to upgrade every 6 months if you wanted to. I have the ONE and i really dont see myself upgrading anytime unless something amazing comes out. The phone really is fantastic.
I'm in NJ so no experience in SF.
Flashing is pretty simple once you do the initial setup which there is self contained programs here in forums that can help simplify that for you. right now im still on stock because i really like the wifi calling and most other roms beyond 4.2.1 dont support it yet. hopefully in the next month the update will be out.
hope this helps a bit.

I ended up pulling the trigger and so far the experience is great.
Stock, out-the-box the device is fantastic, I've never seen something so fluid without some tweaking done to it.
The service in my house is a bit similar to Sprint but WiFi calling negates that. When traveling around I get 4GLTE pretty much every where I go. I have yet to try it in my work environment, but since that is in SF I'm sure I won't have any problems. The only thing is, I signed up for the 2 GB plan. I've never really tracked my data usage since Sprint was unlimited, so I'll just have to wait and see if that is enough.
I am still reading up on how to flash the device, it's a completely different process from my old E4GT. But I am definitely excited to be onto something new and can't wait until I am able to figure out the whole process.
Thank you both for responding to my questions!

Thanks, so far I am definitely loving everything. The phone is super sweet and T-Mobile's Wifi calling helps when cell reception isn't up to snuff. The only downside is the lack of T-Mobile ROMs.

No kernel needed. I assume you're going to get the T-mobile One and not keep the S4 right? Then yeah, no kernel needed. Just root, install twrp/cwm and flash any rom you want from the international XDA section. Its what I've done (except I have the att model unlocked to tmobile) and it works great. You can even flash the Google play edition roms too.

I am using the $30/month 100 min/5G-4G Data. Since for prepaid, t-mobile wifi calling still eats minutes......I've swapped to using Groove IP + Google Voice for all my needs. Ported my old Sprint # To Google Voice for $20.00 and have been happy ever since.
Just have to make sure to setup Google Voice app to get all SMS's and call or chat with T-mobile CS to turn off T-Mobile voicemail, as prepaid cannot forward to google voice properly as post paid.
All in all, I'm very happy with T-mobile, and will never, ever miss sprint. Ever.

No kernel needed. I assume you're going to get the T-mobile One and not keep the S4 right? Then yeah, no kernel needed. Just root, install twrp/cwm and flash any rom you want from the international XDA section. Its what I've done (except I have the att model unlocked to tmobile) and it works great. You can even flash the Google play edition roms too.

Thanks for the reply I'm still debating on getting a tmo s4 or a tmo htc one but my current s4 laggs alot so the htc one seems like the better phone. Also how's the battery life?

I'm also considering moving to tmobile 99% chance I will. I currently have a sprint s4 so how would you flash the international roms? Just flash it then flash a kernel like on the S4 or just flash the rom. Thanks.

Coming from the Sprint GS 2 E4GT, flashing seemed so easy, with all the videos from QBKing77, the thorough guides on how to flash the phone, even the super easy one-clicks, flashing was a cake walk. After reading guides on how to flash the HTC One, I thought that I was going to end up bricking my phone.
Luckily I was able to find some videos from Flow Wolf and QBKing77 which basically walks you through the steps on Unlocking the Bootloader, obtaining root, and flashing the recovery. From there, flashing the ROM works just like it does on Samsung devices, with the exception of having to flash the kernel separately.
Last night I flashed TrickDroid 5.6.0 due to many people saying that you are still able to maintain WiFi Calling. So far, I'm loving it!

I've never had the S4 so I cant compare it to that. Its not great, but It will get you through the day fine.

Flash AT&T Modem on G900T?

Can this be done? I ask because I am using the T-Mobile version on AT&T. LTE reception is not bad, it just can be better, especially in low signal areas? Does anyone have any information flashing the G900A modem for T-Mobile? I have searched and can't seem to find anything on this.
Radio and antenna wise, I believe they are the same device specs, so not like a number of years ago where there were antenna differences between them. T-Mobile radio supports all of T-Mobile and AT&T, AT&T radio however only partially supports T-Mobile (NO 4G AWS band, more limited LTE)
There are a number of people that have compared the two variants and no significant reception differences have been found

Right. I understand that. But what I was asking if we could extract the AT&T modem from the G900A (AT&T Branded S5) and flash it on the T-Mobile S5 (G900T). That way the frequencies would be better optimized.
Now my T-Mobile S5 did pick up Band 4 LTE on AT&T and reception was excellent. This is mostly due to the fact that T-Mobile natively uses band 4 for LTE.

I doubt that has any effect at all. Frequencies don't get optimized at least not on your end. I think the phone does have a priority list for which bands to use but it automatically switches when one is better than the other.

I don't know about that. Perhaps it is not "optimizing" but carriers definitely do something to their modems on smartphones to make them work best with their networks. While the T-Mobile S5 works almost flawlessly on AT&T, the AT&T S5 still gets better reception. Perhaps the difference is negligible, but its there.

I am comparing my signal with the T-Mobile S5 from what I experienced on the AT&T S5. While signal difference in good reception areas is not noticeable, signal in lower reception areas is much weaker. The AT&T S5 would send texts messages almost 95% of the time at my work. With the T-Mobile S5, I am getting about a 10% success rate on text messages being sent.

Yeah that's what I mean. But nonetheless, I still love the phone and this really isn't an issue the majority of the time. Hopefully soon, we can flash an AT&T modem.

The only way I have been able to increase texts going through successfully is by toggling airplane mode. I guess we will have to use that as a work around.
Having an AT&T modem on the Tmobile variant will make the device better handle connecting to LTE/HSPA networks and the phone will switch between frequencies them more efficiently. Now, I don't know if that's possible without bricking the phone.

I think some guy did it with the Note 3. But thing is, the AT&T modem on the S5 has not been extracted.

Extracting the AT&T modem is not a problem I can get it quickly using the stock firmware file. But, still i think it will brick your tmobile s5.

How so? Would it be the same as flashing a T-Mobile modem?

There's your answer right there. T-Mobile released a patch today to deal with poor SMS/MMS or texting issues. Doubt it has anything to do with signal.
Flash the latest T-Mobile update and then see it perform as you'd expect.

Well i was looking to this this with my t mobile s5 with no luck. like another guy said, in good signal areas signal doesnt change but i am in a bad signal area a lot and my phone jst doesnt switch frequecies like it should. I been using att on t mobile phones for a while and installing the att modem but with this one im having some trouble. i have the att modem.bin but when flashing it i get a bootloader response error
You're lucky to get an error and the bin file didn't flash! Please read and search more. There are many threads on xda about similar attempt types. Device-specific modem files cannot and should not be flashed on other devices. They are hardware specific and will cause your phone to stop working if you manage to get it to flash.
Setting up ATT APN settings will suffice for those using att Sim in a sm-g900t.

Yes i realize the risk, and I'm actually not too worried about them. I don't at all think the phone will stop working, however I still can't get the modem on here anyway. I have tried the tar, and bin with no luck. If anybody is willing to put something together I'm willing to test it out. Fortunately in my line of work, it wouldn't be a big deal to get another S5.

I have made all the proper backups. Not to mention I'm not a noob to this, having built a few Roms myself.

If it's not taking in Odin, then I really don't think its going to work. Odin is like the master of all things Samsung for end users. The S5 has a lot of tampering prevention measurements made by Samsung. It wouldn't surprise me if the bootloader is doing a reference check with the modem to see if the modem matches the bootloader.
Also, I wouldn't go about flashing full ATT tar files to the T-Mobile S5. The partition tables are now different in the Galaxy S5 variants when in previous models they were the same. So flashing the ATT full tar could lead to your download mode being wiped.
What exactly is your problem? When you say "not switching frequencies" what exactly do you mean? Like going from LTE to HSPA+ or HSPA+ to LTE etc.
I have created an xposed module for myself that allows me to quickly switch my network preference at ease using a widget. I may share that once I tidy it up a bit. If your issue is being able to switch between HSPA+ LTE 2G etc then the widget should help you. I only use it to force 4G when in a low 4G environment or to force LTE when in low LTE environment.
BTW: What line of work do you do that you can simply get another S5? I'm jealous

Yes I definitely wouldn't go as far as flashing att tar.... And sometimes when I lose signal it takes a heck of a lot longer to gain it back ad t mobile basebands as opposed to art ones. I get another phone about every month and a half to two months so I've definitely tested around on and and also yes when it switches from lte to hspa+ etc it doesn't switch it like any att phone I've had. Takes longer.
And as far as my line of work goes I just mean that I would be able to afford another one if this one broke.

Might be taking longer due to the different radios. Weird though cause if it has an ATT sim and ATT APN configuration, it shouldn't have any delay and function like an ATT phone.
And yeah I'm jealous you can afford a new one if you broke this one takes me a year to save up in order to buy my next upgrade.
