Galaxy S 3 on Rogers (Canada)

I have a Galaxy S3 on Rogers, it is unlocked but has stock ROM. I would like to enable AWS 1700MHz to run on T-Mobile network while in the US.

I read through the entire Forum and am confused with the steps to keep the AWS 1700 enabled once the mod is done.

I know all the details are spread out in the posts, but I dont want to brick my phone.

The mod is clearly outlined step by step, I am just looking for some clear details on how to get the mod to stick on reboot.

Gt-p3100 aws

Hi I noticed that you were using a Samsung GT-P3100. I just bought my wife a unlocked P3100. Have you been able to turn on 1700Mhz AWS band on this phone. Tmobile sent me a Cel-fi signal booster that works well with branded Tmobile phone ( I get 5 bars on my phone). However, the cell-fi will not work with the P3100. It appears that the Cell-Fi does not support 2G. It boosts 3G ( i.e AWS based frequencies). So she has almost no signal at home.

I would very much appreciate some guidance.

Thanks
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gonemad:
Once you back up the NV and then flash the proper file via QPST, if you are not rooted, you simply reboot the phone. It will only stick after that first reboot. You will have to keep reflashing with you pc.

You would only use the nvbackup and nvrestore commands through terminal if you are rooted. It will not stick on our Canadian version.

workaround for Rogers S3

So I am SOL if my phone is not rooted? That sucks. Will the NV restore with the nv backup restore app they mention in the thread work? I only use the phone a few times a year in the States with a ROAM mobility SIM card which uses T-Mobile towers. It's not a big deal if it dowsnt stick all the time, but I would like to be able to enable 1700 on the fly on my phone without a PC. It would be a pain if I needed to load everything up with a PC if my phone battery goes dead and shuts off while I'm traveling.

Hey, so i have a S3 i747m that is unlocked and rooted running stock 4.3. I am able to get AWS to work but i can't get it to stick on reboot.

If i just manually restart after the file is flashed, then AWS works no problems at all.

If i flash the file and at that point do a reboot nvbackup, AWS does not work on that reboot

If i do a reboot nvrestore at this point, AWS does not work

If i flash the file and do a manual reboot, AWS works but

If at that point i do a reboot nvbackup and the phone reboots, AWS does not work

If i nvrestore, AWS does not work

I have tried using terminal emulator, gscript and the app but they all have the same result.

Any help would be appreciated as having a way to get it to work on a reboot or battery pull etc when not near a pc is important.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gonemad:
It has worked for me both ways. Done the reboot nvbackup immediately after flashing and also after the first reboot. It has always worked after doing the reboot nvrestore.

Just thought of something,, when you are doing these commands in terminal for your reboot nvbackup, are you remembering to do the "su" command first, to bring you into root? Then doing the reboot nvbackup.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] GalaxyS3S:
Thank for the reply. Gscript and the app have su rights and i did su in terminal. Going to try a few things today so hopefully can get it to stick.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] GalaxyS3S:
For whatever reason i don't think it's going to stick. Thought i was on to something with enabling su at boot but that didn't work either.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Angry Black Man:
okay, so i have an i747u and after applying all this and then getting the asterisk, my cell indicator turns to "disconnected". no amount of waiting yeilds the expected results.

prior to trying this, i tried that AWS fix that involves flashing through odin, but that didn't work either - my network died when i did that fix, and i've since reflashed the modem to the JB version which as least gets me back to square one which is where i DO NOT want to be.

any ideas? this is making me beyond angry

hey would this work on s3 i747m 4.3 or do i have to downgrade for it to work
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] crazyut:
I followed the original post and it did get stuck on the reset/reboot part which based on your post was a blessing in disguise (I am using Android 4.3 on Telus SGH-i747m but without the 4.3 bootloader, most likely is 4.1.2 bootloader since I downgraded from 4.1.2 to 4.1.1 to unlock it, then back to 4.1.2, then later upgraded to 4.3 from the XDA site). Of course by the time of 4.1.2. to 4.3 upgrade, it was then SIM unlocked and also rooted.

You're advice is awesome.

I just had to remember to su once the terminal emulator opened before typing the reboot nvrestore command (blonde moment). A small price to pay to save $250 on another s3 (to go with my s4, note 3, note 10.1 2014 (all international)).

USB port is not working...

I need some quick help on this. I am not really worried about the change sticking I just need some help getting it to work at all in my situation.

I have unlocked i747. I have T mobile unlimited plan and sim installed. I need to get it working on AWS 1700 band.

My main problem is the usb port is jacked up. It will charge, but not make a data connection to any PC. I have ruled out the PC as the problem. I fear I have a physical issue with the i747.

Is there a way for me to make the changes to get the phone working on 1700 without PC connection? Perhaps terminal emulator or some other way?

I am stuck at a job site for a moth or more and could really use the connection. I don't want to buy anything because this isn't my permanent phone.

Thanks in advance for any suggestions!

Weirdest thing happened yesterday. Was at work and my phone was dead for most of the day. When I was leaving, got in the car and put it on the charger, Waited a few minutes and booted it. Was waiting for it to fully boot so I could do the nvrestore thing, but as I unlocked the phone, I noticed it picked up my network and had the 4G LTE up top. IT STUCK!! I don't know why, whether it has something to do with being the last time I had my phone off was at least a month or so. Gonna try my wife's phone and see what it does. If it sticks, then I know it's probably something the carrier did.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gonemad:
I just rebooted my phone normal two more time and the AWS stuck. Not sure why it is doing this, but it is working. Tried my wife's with a different rom and still had to use the nvrestore method with it.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
Is it connecting to aws "4g" on 1700 or connecting to 4glte meaning lte has come to your area? If it is that lte is in your area maybe your wife just needs the fast apn to connect also. Check your band and see.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gonemad:
My carrier is new, and was lte from the start, it never would connect to my carrier unless I did the reboot nvrestore method. MY phone and my wife's are identical. My phone is running what's in my signature, hers is just a stock rom auto rooted and still needs to reboot nvrestore to connect to the network. How do I check the band to confirm. If this is true that it actually is sticking, I wonder if letting the phone go for so long without a reboot and then running the battery completely dead had anything to do with it.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
I'm using tapatalk and don't see your sig.

I have an i747u and used to use nvrestore to connect to aws 1700.(4g) Phone only does 1900 originally.

But it Always connected to tmobile 4gLTE as long as I had the right apn and it was in the area. There was no need for nvrestore to connect to LTE.

I'm running android 4.3 s3rx rom.

Strange behavior

So when I run "reboot nvrestore" I get a bootloop and have to re-odin my rom (stock 4.3 +root). Anyone have thoughts as to why this might be happening?

EDIT: an odd thing to note, after I re-odin the "nvrestore" operation seems to have worked as I don't need to re-apply the fix. Odd eh?

Model =i747m (Canadian Rogers variant)

Bootloader = I747MVLDMF1

Baseband/Radio = I747MUMUEND3

Other than not being able to reboot this is working quite well on Wind here.

After second reboot it is not working anymore for AWS

I have a Rogers S3 SGH-I747M that has been upgraged to 4.4.2 Android by Samsung Kies (Unlocked but not rooted). When I restore the NVData file and reboot the phone I am able to use it on WIND. But if I reboot the phone one more time I will not be able to use it with WIND anymore. The same story happens with MOBILICITY. I very appreciate any help.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SomethingAwesome:
This is just how it works for now. Unless someone picks up development/hacking on this 'feature', it will not be a persistent change.

The only other issues I've noticed is that Bluetooth doesn't appear to work. (I don't use it anyway)

I've found that it is possible to run the phone pretty much indefinitely without rebooting as long as you keep it charged up.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] matsix:
Is this supposed to stick on the I747? Because it did for me. My area uses 1700 aws for LTE and after using this I still didn't get LTE. After going over my friends house I got it probably because he lives closer to the tower. It stayed even when I went back home which was cool. At this point I've already rebooted it multiple times after applying this mod.

I noticed also that when I get a call it goes back to 3g. I ended up using an app called LTE discovery and made it run for a while and it basically kept going through networks and it eventually got to LTE. The app also allows you to see which band you're on and that's where I found out I was on band 1700. Which means it stuck after rebooting multiple times.

I know that the other hack to enable 1700 sticks on reboot only on I747 and not I747m but does that apply to this hack also?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
The I747 does 1700 lte out of the box. (4gLTE)

Just not 1700/2100 Aws. "4g" or 3g hspa+ as it is called by everyone except tmobile.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] matsix:
I've had 3g hspa+ before I did this mod. And I only got lte after I did this mod.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
This mod doesn't enable LTE on the i747u. If you didn't have lte it was probably not turned on yet in your area or your apn wasn't correct. Check att specs for it. Band4 lte was built in. It was only 1700 aws or umts that wasn't enabled. Therefore no tmobile "4g" on the 1700/2100 band.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] matsix:
Okay well then I'm very confused. It was active in my area for a long time. My brother has a tmobile lg g2 and he has had lte since he got the phone. I'm also fully aware of the APN's and I've always had it using the LTE apn. Before I used this mod my phone would sometimes show LTE but it would say no service. It wasn't until after I did this mod that It actually started working.

So yeah I'm sure you're right, I'm just confused.

I have been using a Virgin mobile i747m successfully on wind for about 6 months now on a few different builds. After accidentally updating to 4.3, I landed on using the s3RX Rom for my daily since the stability can't be matched.

What I've found is the key to having the nvdata "stick" is to perform NV backup after pushing the t999 data using qspt but BEFORE rebooting the phone. If you manually reboot or use a terminal command, the mod will work once, but fail to reapply on further reboots.

The data is applied on reboot, & "Reboot nvrestore" performs those tasks, in that order. So if you reboot manually first, the mod will take... But "reboot nvbackup" will then reboot the device, wiping the pushed t999 data, then nvbackup the original i747m data, causing the mod to disappear . I hope I explained that clearly, but here's my process

*#0808# to get to usbsettings menu

Select rsdis+dm+modem (don't press OK or leave menu)

Push t999 data to phone using qpst utility on computer

(I always get an error on qpst. Something about brew files... No biggie.)

When qpst is finished, select mtp + adb on usbsettings. Now press OK!

In terminal

/su

Reboot nvbackup

Device will reboot, and in top left of screen you will see 2 copy messages as the Samsung logo appears.

On boot, the device will connect to aws after about a minute, depending on your network selection preferences & signal strength. From that point after every power down or reboot

Su

Reboot nvrestore

Will successfully reenable aws connectivity. At least it does for me. Every time :-\

any suggestions i don't wanna flash if it might brick would it?

or if you can find some way to edit i747m modem with some of the t999 code regarding to NV Restore and change the default restore in the i747m modem to the T999 ASW band Instead of stock

And i was wondering is anyone has found a PERMANENT fix?

Tried this tonight, applied it, got big "4G" notices all over the place. Power cycled, still working.

Just retested because I'm paranoid. Powered off, removed battery, waited 15-20 seconds, put battery in, powered on, boom. Turned off Wi-fi so I could see band type, showed LTE, then HSPA+, then HSPA, then 3G, then back to HSPA+. Life is excellent!
