I have not noticed a speed difference between the two Apns on my i747. Only noticed the difference between my t999 and i747.

Lte however worked with my i747 and epc apn at my work but not near our church 30 miles away. Switching to fast apn enabled lte by our church and at my work.

It looks like not all towers connect lte with the epc apn. I have both and check both if I am in an area without lte.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] pre4speed:
I have what may be a silly question but reading thru the thread has confused me so much. I did the mod, and seems like everything took. I did the mods in the OP, then flashed the tmo twrp, then a tmo stock rom (can't remember which, but by enewman). My tmo sim is not active yet, but under mobile network type it said something like LTE. Anyway, can I now flash a jellybean modem and the mod will stick, or should I leave the tmo ICS modem? If I can, do I flash a t999 or an i747 or even a t999l? Thanx in advance for any help clarifying.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
No for the mod to stick you have to leave the ics modem alone.

And never flash the tmo, either version, modem. while on this phone it wont brick it, you will get no service at all until you put att modem back on.

many phones you would brick by putting wrong modem on.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SuperAfnan:
For me there was a speed difference. The epc APN gave me 4 down an 2.5 up. And the fast one gave me 1 down and .5 up. I have no idea why I'm getting slow service right now. Hopefully it's a good sign that T-mobile is refarming their towers and adding LTE. :) But it could always just be a slow day. :rolleyes:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
I live in an area with LTE. With this mod or the NV backup mod, I get LTE, 3G (UMTS), H+ and very rarely H.

Without the mods I only get LTE, and in areas where I'm supposed to get 3G/H+, I only get EDGE. I thought everything was supposed to work out of the box in refarmed LTE areas?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Product F(RED):
Refarmed does not mean LTE. Refarmed means that for HSPA+, it's running on 1900 MHz instead of 1700/2100 MHz. AWS LTE is different than AWS HSPA+. It's like comparing 850 MHz 2G and 850 MHz 3G; same frequency, 2 different protocols. However, most newer (in the last few years) AT&T LTE devices do AWS LTE out of the box. You should get LTE and EDGE at the very least.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
Ah, I knew they weren't the same thing, I just thought that the refarming and LTE deployment went hand in hand in T-Mobile's case.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
No, but in most markets they are.

Put it this way in most markets they refarmed for 1900 HSPA they also put up LTE enabled antenna's.

But they decided to deploy lte so fast they put lte up in other areas besides those that were already refarmed.:good:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
Hm... Boston is on the list of "Modernized Markets" http://support.t-mobile.com/docs/DOC-5736, yet I just don't get 3G or H+ on CM 10.1 with the newest radio.

Using the CSC and Modem from this thread I only got 3G but no H+. Using the NV method, I get everything, but then I'm stuck on an old CM version that has the 3.04 kernel and supports the diag mode scripts. Restoring a newer CM and doing "reboot nvrestore" causes bootloops.

All I want is to be able to use a newer CM/PA ROM with one of these methods. I feel like i'm missing something in this process, lol.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
I used cm-10.1.0-d2att and scripts worked fine, I don't know how 'old' that is though.:eek:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
Which release? The stable one? Anything using the new Linux 3.4 kernel won't work with the diag scripts from what I've read/experienced.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
Thats a great question, I dont recall if it was the stable version. I just sold the phone today so I can not check on any nightly's.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
Noooooo. No worries. I'm about to try this again.

Install newest PA nightly, make a nandroid

Install a stock ROM and then flash the Modem and CSC over it

Restore the PA nandroid

Should work, right?

Edit: Ok, I flashed Stockorama and the Modem and CSC over it. Chose the 1700 band with #*2263#. UMTS:3 started working, but now I get no HSPA/HSDPA. The stock rom shows 4G in the status bar, but Settings > About Device > Status never changes from UMTS.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
when Idle the status will be UMTS, its only when active connection and downloading is going on that HSPA shows.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
Yep, and that's how it worked when I used the NV method.

With this one it never kicks up to HSPA. Stays on UMTS the whole time.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
Never seen that happen, is that only on the aosp type rom?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
Nope, It's the same case on Stockorama as well.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jojo_whit3:
What modem are you using?

I've seen this happen to my phone when I don't use the LK3 modem. Flashing back to the LK3 modem has always restored my HSPA+ functionality.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
I thought we had to keep with the modem from this post?

I ended up updating my bootloader to the newest version. That gave me hspa back! But then after surviving quite a few reboots, all of a sudden I'm back on only Edge and LTE....
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jojo_whit3:
Oh ok. Yeah, I did the same thing a while back...flashed the Modem and CSC, but then I was also stuck at UMTS. Even when I ran a speedtest, it would never ramp up to HSPA. I always assumed it did this because I was using an ICS modem with a JB ROM.

The only way I've been able to get this mod to work 100% is to use the NV Backup app. For starters, I was using Task's AOKP and was already on the latest LK3 bootloader. I flashed the Modem and CSC files from this post via Odin. Since Odin does a factory reset, I restored my data in recovery from a nandroid backup. I used the NV Backup app (http://d-h.st/irk) to create a backup of the NV data with AWS enabled. Afterwards, I flashed the LK3 modem in recovery, rebooted, and then used the NV Backup app to do a NV restore. This worked to get HSPA back, but it's not persistent through reboots. Anytime I turn my phone off, I have to do an NV restore to enable AWS again.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
You're my hero right now. This worked! I have no problem rebooting to get AWS. I set up a widget that does "reboot nvrestore" with one tap.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] post-mortem:
How did you do that in a widget?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
https://play.google.com/store/apps/details?id=nl.rogro.GScriptLite&hl=en

Just type "reboot nvrestore" without the quotes as the script. Make sure you check the "needs su?" (root) box. Save, and then the app should be in your widgets when you long press on your home screen. Select that script and you're all set.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
Oh if I had known you were ok with that method I would have linked you to

http://xdaforums.com/showthread.php?t=2344627

As that is exactly what this is doing.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] davidjavid:
With that exact method, you can't get into diag mode with the newest AOSP CM based nightlies. Restoring to a new nightly and then restoing the NV backup caused a bootloop.

This similar method of using the nv backup from after flashing the Modem and CSC works without causing bootloops and lets me have an updated modem as well.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
:good: cool, what works, works right.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SuperAfnan:
Right now I'm hoping that T-mobile can refarm the area around my house, and I won't have to rely on this mod anymore lol. I haven't tried the NV backup method yet but I probably will once I decide to flash an AOSP Rom.

There's also LTE near Orange Park mall. :)

Moving up to JB?

Okay, so I've read this thread from beginning to end. Super noob to all this. I have a million tabs trying to learn me some things before I ask questions but I guess this particular phone and this particular thing that we're doing here seems to be pretty new and thus I'm getting so many conflicting answers.

I flashed my unrooted i747 with the t999l files from the OP. Works no problem on Tmo, getting my higher speeds and I didn't have to do a damn thing after that. Still on ICS, though, and I'd love to get JB back on this thing. Someone pointed to http://xdaforums.com/showthread.php?t=1771021&page=86 for a close to stock rom with improvements.

Root first, then get TWRP, then install through recovery? Correct?

Sorry, trying to swallow this all at once.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SuperAfnan:
You can still install JB with the toolkit from mskip in the AT&T development forum. Root, twrp, and finally flash a custom JB rom like deTmobilized. You can't flash AOSP roms though. :( For that, use the NV BACKUP method. :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Jinsoku:
So if I just want JB I just use mskip? Or you're saying get mskip, root, twrp, and then flash? I don't necessarily need/want a custom rom, (yet. If I learn to flash with ease I may get addicted to this). I just want to get back on JB for now, worry about all these custom roms later.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] monkeysez:
Will any updates be made for the new modem that was released today?

Also, can I flash a custom rom and still get this mod to work?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SuperAfnan:
Yeah just use mskips kit for now. He should have an option for just that. You can still run stock with everything hacked/modded at least. :thumbup:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Jinsoku:
Awesome! So get mskips kit, find the JB rom for the Att i747 even though the phone thinks it's a t999l, got it. Thanks, man! :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DanteDFG:
WARNING

Guys if you can read this, and you're uder the influence at ANY time while flashing these files, DO NOT treat the phone as a T999! I was unfortunate enough to be thinking "Hey let me update those bootloaders since it has old T999 ones" and now I have a corrupt Bootloader! Whatever you do, ALWAYS flash the I747 radio/bootloaders, this ISN'T ANYTHING like the I727 and T989 (They could run the same bootloaders, kernels, modems and roms) Or else you'll end up with a S3 in Cyber-Heaven
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Jinsoku:
That's what's so confusing. I've seen people her say to get the files for a t999l and treat it as such, but now I'm seeing otherwise, which is why I've been so hesitant to continue. Is there something I'm overlooking?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SuperAfnan:
Well from what I am know, you must use the i747 files always, unless the mod tells you otherwise.

Even though you're using it on T-mobile it is still not a T999, nor is it a T999L.

In the toolkit make sure you choose i747 as your device. NOT T999 or T999L.

If you do this you'll be safe. :)

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] haroonie:
I was able to flash in odin the op's directions and get working on my i747 device. I then flashed d2tmo's version of liquidsmooth (after modifying to bypass bootloader check) and everything works great for a few weeks with the given kernel (CM 10 3.4 kernel). However, when i flash ktoonsez's kernel (cross-compatible with i747 and t999), the device reboots every 30 seconds or so; so i have to flash back to CM kernel.

Has anyone got a different kernel to work besides stock or CM kernel with this mod?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] aspirin240:
I just completed this mod and everything works, except that I would like to get JB back. Wondering will it work if I get the ATT i744 4.1.2 stock rom and flash it thru the recovery? will it revert it back to original like before the mod?

Thanks in advance,

Clarification question on flashing these files?

Hi all - I'm about to bequeath my ATT S3 to a friend on Tmobile. I'm presently running i747zVLDK4 (4.1.1), and it's been so rock stable haven't messed with it since. And, I don't need/want to trick it out, because the friend who's getting it is absolutely *not* a power-user.

So - my basic question is - the OP didn't make this exceedingly clear - do I need to flash to stock before flashing these files, and then flash to whatever custom ROM I need/want? Or, can I probably (yeah, I know, no guarantees) just flash these with what I have right now?

Many thanks with any insight you can provide!

I don't see that version anywhere. This is a usa i747?

---------- Post added at 10:34 AM ---------- Previous post was at 09:53 AM ----------

This worked for the US version. I would do the CSC file and the modem only. Make a nandroid first. With that I747u on T Mobile you can flash T Mobile roms but you need to keep the bootloader, CSC and modem files from the I747u or the engineering T Mobile files.

Flashing T Mobile ROM that is somewhat stock should enable wifi calling and text messaging.

---------- Post added at 11:08 AM ---------- Previous post was at 10:34 AM ----------

I live in an area that has been refarmed by tmobile(phoenix az). Many areas have lte and others have 4g on the 1900 band. Because of this I used the nv backup method instead. I only run the nv restore when I leave town and head to areas that are not refarmed. I use stockorama v2 rom. I removed the asserts and installed it with tmobile options. (Carrier and kernel). Then I edited the build prop in a couple spots to show i747 instead of t999 just to look better in about phone and signatures .

Currently im running jellybam 10.2 and love it and would like to keep. From what i understand i can do what was mentioned in post #925, and that is install the OP files then make an NV backup, install desired ROM then restore NV backup and then i will be off of edge network.

The 3rd link looks to be working. You should also be able to just flash the modem and csc file.

back up your nv data first. Use the terminal command "su reboot nvbackup"

Then boot to recovery and make sure to nandroid back up.

Then boot to download mode and odin flash the modem and csc.

After reboot you may need to go back to recovery and wipe cache/dalvik cache.

Then reboot.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
First you need to backup. You need to read about nandriod back up.

Then read about nv backup.

Then the instructions for flashing the modem file and csc file are in the instructions that are with the download.

Basically you will just choose modem and csc not bootloader and pda/platform.

Anyway to get an updated modem that does aws 1700.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] VQ30DE:
I've read the thread--really great work by everyone involved. I wanted to confirm a few things:

If I put a T-Mobile SIM into my AT&T i747 (unlocked, running CM 10.2 d2att nightly), it will work for voice and data, including LTE, but not 3G/HSPA+, right? I'm not too dependent on mobile data so I think this would be OK.

I understand that T-Mobile is "refarming" a lot of their towers and has LTE support in most larger cities, but if the LTE connection is poor it can be pretty slow, and 2G is really slow. Will they be upgrading all towers to support the bands the i747 supports in the near future, or is 1700 MHz AWS going to be important for a long time? In other words, am I likely to be frequently frustrated with not having 3G around town?

Is there any way to do the flash suggested in the OP and then flash a custom i747 ROM (e.g. CM 10.2) and have it stick without special rebooting/reflashing procedures? It sounds like no, but I wanted to confirm that. Also, the wifi calling feature will not be available, correct?

I really like T-Mobile's new no-contract system, and their family plans are great. I calculated that if I switch from AT&T (2 lines) it will save $200 over the next year even though I'll have to pay hefty early termination fees to AT&T....

Bootloader > BAM Android ROM

I am not super savvy with android but I followed the directions and i'm getting way better speeds on the i747 using t-mobile.

thanks for all the info here!

..and to anyone who is trying to figure this all out...it was WAY easier for me than all the pages of discussion suggested on first glance.

my current issue is this....

i really love the BAM Android ROM (formerly Jelly-BAM).

When I try to install BAM Android 1.0, it gives an error.

I believe this is because I changed the bootloader per these instructions.

Is there any way to get BAM Android to work after following these instructions for using the faster data speeds with the i747 on t-mobile?

thanks!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
All that is required for this to work is installing the csc file and modem from odin. If you made a backup that included your bootloader you could restore it then flash just csc and modem.

Otherwise you could search for new flashable bootloader and modem for i747 to flash, then restore your backup or flash bam. Then flash these csc and modem files.
