hmm...

I have an I747 that I setup for my kid to use here a while ago... (cracked screen... but works and the price was right...) I flashed it with the ALJ2 rom that enables 1700 mhz ... so the "latest" 4.x stock rom that I can run is 4.0.4...

What is the best method to end up with something I can run a newer rom with? or can I simply run a CM/ASOP rom and have a 4.4 experience for him?

AWS Trick sticking

I haven't posted on xda in a very long time but I read all pages of this thread and I think I found a way for the AWS mod to stick on the i747m model. Each time you reboot the device you'd have to run the nv restore command in the terminal so why don't you guys make a script to automatically run on boot so you don't gotta waste your time typing it manually. Do you think it'll work? I was gonna try it out but the i747m I'm testing out is not gonna be unlocked until tomorrow can somebody try this method I thought about and see if it works?

I was trying to post the link but it wont work if you guys wanna try just pm me I'll send the link that way if I can.

It works Great and signal is stable!!!

Good Morning Everyone,

I did everything every single step, I got my 4G signal working without calls being drop or internet. The only thing I did have to make sure is to have the phone in PDA by dialing *#7284# and RNDIS+DM+MODEM by dialing *#0808#. After that the phone was able to connect to the computer without problems and finally able to accomplish the task. I download i747NV with AWS for my samsung galaxy S3 i747 with android Kitkat. :)

Samsung Galaxy S3 i747

Genuine Android Kitkat v4.4.2

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jblparisi:
And you have verified this after every reboot ?

Follow the instructions on OP :

If you'd like to make sure you are able to use the 1700 band.

1. In your dialer press *#2263# (*#BAND#)

2. Press WCDMA Band Preference then WCDMA 1700.

3. Press the menu key and then select back. You should have an asterisk next to WCDMA 1700 now, and after a few seconds your data connection should start on that band. Enjoy!

4. To revert to full bandwidth: Press the menu key, select back, and then in the service mode menu select automatic.

Did you guys flashed stock with odin ? The new bootloader and everything? Btw this is a i747m flashed stock 4.1.2 with odin. Now its sticking... tested every reboot.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] upncoming:
I've been pulling my hair out playing with this! A quick temp fix I found while playing, but haven't tested with the t999l backup just yet because I'm not near my computer:

1. I'm on stock rooted 4.1.2

2. I flashed the modem and csc from the other thread via mobile odin to enable 1700MHz (Takes 1 more reboot after the flash)

3. I went to terminal emulator and typed without quotes: "su" enter, and then "reboot nvbackup"

4. Your phone will reboot and run two quick commands to backup your nv data to nand.

5. I flashed the latest I747 modem and lost 1700 MHz after another reboot. (The band was still there after the initial flash)

6. I went back to terminal and restored my backup by typing: "su" enter and then "reboot nvrestore"

7. The phone rebooted, ran the restore commands, and the 1700 band was back.

The restore command will have to be run after every reboot, but hey it keeps it going for now... I'll keep working on a permanent fix. I've got plenty of ideas. I just need the time to try them!

Again, I have not tested this by loading the t999l nv backup. It's from using the other method to enable 1700 and then backing up. I'll give it a shot the other way when I can sit at a computer and load the qcn file again.

I tested this basically to see if we could have done it all along... looks like we could have.

Edit: Corrected commands.

I wish we also had the csc file in flashable format to try. It would be interesting to try the nv, csc and modem from t-999l.

It would also be interesting to flash all t-999L files once they have them all working. That is jtag territory though if it didn't work.

Does anyone know of this app? I want to try this, but am on Task's AOKP ROM, and the USSD codes don't seem to work under that one. Can we just install the stock dialer, perhaps?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] upncoming:
I think the ussd will only work on touchwiz. If you want to test a workaround for this:

1. Install nova launcher

2. long press the screen

3. Hit shortcuts and then hit activities

4. Scroll down to PhoneUtil and hit it

5. Choose the sub-option PhoneUtil with SetportUartUsbMSM8960 written underneath it in small letters

That should setup a shortcut so you can put the phone in diagnostic mode. I can confirm it works on touchwiz, but it needs to be tested on roms that use another base.

Sorry, I got tied up on wife duty. Don't use a normal T-Mobile modem. It won't work on this phone since it's AT&T. Go to this thread: http://xdaforums.com/showthread.php?p=28724736

It'll work better for your needs since this thread we're in is for a work in progress. That one is stable.

Flash only the modem and csc files via Odin at the same time. Don't bother with the rest. Those two files are all you need. The phone might need a reboot after you flash for the fix to show up.

Let me know how it goes. :beer:

Many of the dialer codes will only work from a stock TouchWiz dialer.

Hey guys, any development on not losing aws unlock after rebooting? If there was no fix yet, what do you guys do to re-enable again without NV backup restore through PC? thank you!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jinxhyped:
Download any script program (i just edited the "reboot" script in busybox installer)

Follow the dialer code method outlined numerous times in this thread to replace your i747m NV data with the T999 variants listed here with QPST.. Now this is the important part... Do not reboot! Instead perform the "reboot NVbackup" command. This will write the T999 data to the devices NV backup storage. Once the backup is complete & the device reboots, you should have aws connectivity! ... Until the next power down.

Now the long way to restore it is just to use terminal emulator for

/su

/reboot nvrestore

Which will reboot the device and load the backed up Nvdata. I just edited the reboot script in BBinstaller to include the nvrestore command. Now whenever my batter is pulled or dies, when I power back up the order is

Boot, no Aws

Open BBinstaller,click reboot script

Wait through reboot

AWS connects about 20-30s after startup, depending on signal strength

Profit

This is how I understand it in simplest terms. QPST doesn't apply the new Nvdata until reboot. The NVbackup /nvrestore command also takes place after reboot, so if you wait until the device is functioning on aws before performing NVbackup, then the t999 data is wiped on reboot and you're just backing up the reimplanted i747m NV.

I ran this mod for 2 years on my daily device with Wind in Toronto. I never had to reinject t999 via PC beyond the first time. This was on S3rx final TW Rom.

I hope this helps, because I no longer own the device & will shortly unsubscribe to this thread.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Gonemad:
OK, I have been following this thread for quite some time now,,,and just to summarize everything and maybe answer some question,,

There is NO permanent fix for this. You cannot permanently write the NVram

You must be rooted to use any script editor or the /su method through terminal??

If not rooted, never let your phone die or reboot or you will be restoring via the QPST method all the time?

I think this pretty much sums it up in a nutshell if all is correct.

I can confirm this also works on the other method. Just make sure you backup the nv on terminal right after you flash the nv backup on the OP instructions prior to rebooting. Then every time you lose the 1700mhz band you just have to run restore nvbackup and you are all set till we find a more permanent fix.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:

Ok I am not sure if you meant it this way but I flashed the tmobile modem, the t999l version, which of course gave me no signal.

I opened cdma workshop and connected to the phone, it connected, I went to send the samsung password and it said not correct, so I sent 000000 for the spc it said incorrect.

So I just tried reading nv items and got

alot more of them actually.

then tried with qpst and got unknown error.

the backup is way too short but maybe you can make something of it.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:

This way is disabled. change it to

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] New Optimus:
Ok more checking and retrying I find that I can actually replace the item 01877 in efs explorer (part of QPST) and on the next reboot it will have AWS enabled. but after doing that I check that file again and its back to disabled.

So I think there is something that is changing it after boot is done. I tried this in both cm and in stock rom and it does it the same way so it might be part of the kernel?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] upncoming:
Good catch! I'm going to take a shot in the dark over here. I see 2 ways of going about it.

1. We figure out which value to change in recovery.img and/or possibly boot.img to stop the phone from overwriting the NV Data. Or...

2. Edit the modem so it writes the values we want to the NV.

I'm going to take the info you found and apply it to the modem. I've found about 3 spots that match your data, so I'm going to change them all and give it a shot. Think un-bricky thoughts...

Edit:

Ended up having 3 good possibilities and 2 maybe blocks to change. I tried changing the first 3 in every which way I could. All I got was loss of signal and loss of service mode. :( I'll play with the other 2 tomorrow probably, but I'm thinking it's time to go back to the drawing board...

I was reading that the sg3 has a nv backup that is injected during the boot process, one reason so many have had imei 0'ing problems, but trying to replace that with the modified backup (so it will always inject the aws enabled nv) does not seem to get anywhere. I read about using adb reboot nvbackup, the same as has been mentioned here. but that does not do it so its not reading from that location for the backup we are seeing.

I plan to look into the modem itself (assuming I can look into it with my linux system) maybe its coded into the modem itself.
