I wonder... is a new .qcn file all that is needed to make this method work on the newer modems?
[AT&T Samsung Galaxy S 4 General] GuyIncognito721:
Correct. Unfortunately, no one has been able to come through and deliver on that QCN file
[AT&T Samsung Galaxy S 4 General] dhomas:
Thanks for these instructions. I'm unfortunately getting stuck at a certain point. For reference, here is my situation:

- I've been able to perform these steps while I was on 4.2.2. I got access to AWS under this version.

- When I got the OTA upgrade to 4.3, I lost AWS. Furthermore, I was no longer able to flash the qcn file on this new version (but I was able to connect to the phone with QPST).

- I followed the instructions above, but now my QPST no longer detects my phone. :(

No matter what I do, my ports are detected, but the phone never connects. Anyone get this issue? If so, any solution? Thanks in advance!
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Did you change the USB mode?
[AT&T Samsung Galaxy S 4 General] dhomas:
I went into the *#0808# menu and changed the "USB Settings" to "RNDIS + DM + MODEM". The PC installs the drivers after this. I see the COM Ports in Device Manager, and they are available in QPST, but no matter which port I use, QPST always says "No Phone Detected".

I'm not sure what I'm doing wrong. It has worked for me in the past...
[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
When I had this problem I had to use a different USB cord.
[AT&T Samsung Galaxy S 4 General] dhomas:
Thanks for the tip. I was really hoping this would fix it. I tried with 2 new USB cables on 3 PCs, with no luck. I also tried setting the phone to RMNET + DM + MODEM (RMNET instead of RNDIS). This looked promising, since it installed with different COM ports when I connected it to my PC, but I still didn't get it connected to QPST.

Anyone else have any ideas?

Hi all,

Here's an update. I was able to get QPST to recognize my phone using an updated version of QPST, build 411. You can find it here:

(N/B.: Do NOT download build 422. It apparently contains a keylogger trojan. See here for details:

However, when I try to backup my qcn or restore the one in the initial post, I get get errors.

Here is what I get during the backup:

Status: Memory Backup Failed

Errors: Disk Error while writing to file.

Here is what I get during the restore:

Status: Memory Restore Failed!

Errors: Received an invalid command from the phone.

Any ideas on how to move forward?

For reference, here is my situation once again:

- i337 on AT&T

- While on 4.2.2 (not sure which radio/baseband I was on), I got the tweak to work.

- Since I was on stock ROM, I got the OTA upgrade to 4.3 mk2. This broke my radio tweak and left me without AWS.

- I just restored my phone to factory defaults (using this thread: http://xdaforums.com/showthread.php?t=2573080)

- I rooted my phone (using this thread: http://xdaforums.com/showthread.php?p=48392009)

- I installed SafeStrap (http://xdaforums.com/showthread.php?t=2448925)

- I installed the radio from MF3 successfully (download here: http://d-h.st/ReU, procedure here: http://xdaforums.com/showpost.php?p=50591775&postcount=725)

- I tried the procedure in the OP again and was able to see my phone in QPST, but was unable to flash the qcn

Did you check if your phone was selected in the "DOWNLOAD SOFTWARE" window and have you tried other USB ports?

Thanks for the tips. I made sure that the phone was selected (I actually removed all unnecessary ports) and I tried other USB ports as well. Still can't get the qcn file loaded (or backed up).

Hi, With a Galaxy S4 thats 4.3 upgradable. What would you say is the easiest way to enable the AWS Mod. Do you have to root? Is there a new qnc file?

All The Best
[AT&T Samsung Galaxy S 4 General] sja44:
Finally got the AWS mod on my Telus 337m

here is the extra I found by user DUF on galaxys4root.com:

==========================================

You’re the Man!

I done with Fido SGH-i337M and use it with Videotron HSPA+

So I flash modem.bin from videotron stock rom SGH-M919V first.

And Use this trick to get out off the “not getting the (0) detection on QPST”:

1) enter *#9090# on dialer

2) CLICK on the #2 – DM/DUN over HSIC

3) phone should reset; just connnect the cable back in and try QPST again

Work like a charm.

===================================================

This is what I needed to get QPST to work. I needed *#0808# to set the RNDIS + DM _ MODEM

All the rest including the needed files is as described in this thread.

Well done DUF!

---------- Post added at 12:54 AM ---------- Previous post was at 12:42 AM ----------

===============

Can confirm AWS .. network: WIND .. NOT ROAMING

Also can confirm that TELUS LTE still fine (band 4)

===================

Can someone explain the 9090 menu?

1. DM/DUM over HS-USB *

2 DM/DUM over HSIC

For the record this is the newer hardware version of the S4 on 4.3 baseband i337MVLUEMK6

This is the one that none of the unlockers can unlock. Paid Telus their $35- after the 90 day period.

NOW will this hold when 4.4.2 rears its head? Anyone?

Not a clue.. that's why I asked. I did check and leaving it seemed to do no harm. I did put it back just in case.

So I dont have to read 75 pages of info, I am on MF3 still with the AWS mod with my ATT GS4. I have NOT upgraded to the newer versions even though I would like to because I have upgraded my friends phone and that made it impossible to redo the AWS mod. Is there a way for the MK4 or new Kitkat release to install the AWS radio back on the device? If so, how?

TIA
[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
For Mk2, you can install the MF3 modem and follow the guide to get was. For NB1, you should be able to when a root method is found.

I have an I9505G Google Edition S4 on T-Mobile in NYC with 4.4.2. I get no HPSA+ or LTE. Google tech sent me a link to a Youtube video which demonstrates the QPST install.

I successfully installed phoneutil.apk and QPST. The procedure failed at the step where I dial *#0808#. When I enter that, the phone reports "USSD code running..." briefly before showing "Unable to process request" Without this step, the Samsung USB Modem drivers did not show under Ports in Device Manager. No com ports show with 0 in the Phone column in QPST and the .qcn file can not be transferred.

Is this a 4.2.2 problem? Do I need a different code?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You should never flash this on a different phone model, ever. Also, the i9505G has both AWS HSPA+ and AWS LTE already. You shouldn't need this mod.
[AT&T Samsung Galaxy S 4 General] ruidh:
A) Google told me to do it and

B) I'm getting neither HSPA+ nor LTE on T-Mobile.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Google (tech) told you to go to XDA and follow this mod? Google must be smoking crack...

As I told you, this mod is not for your phone model. Your phone should be getting HSPA+ and LTE out of the box. If you've exhausted every other resource (e.g. flashing a modem for the i9505G), then talk to Google about a warranty replacement, because doing this mod will only make things worse.

[AT&T Samsung Galaxy S 4 General] Product F(RED):
A modem flash is pretty simple to do. But anyways, can I get a screenshot of your network mode setting? I have a theory. You're sure you live in an LTE area, right?
[AT&T Samsung Galaxy S 4 General] GuyIncognito721:
The T-Mobile variant is getting their update now. So if anyone has access to one and can get the QCN off of it (build number NB4) that would be awesome for those of us looking to update.
[AT&T Samsung Galaxy S 4 General] ruidh:
Yes. NYC is an LTE area.

But the solution has been found. It appears that my 'very old SIM was not properly provisioned for LTE. Replacing it with a new SIM brought LTE right up. T-Mo replaced it without charge.

I don''t know why the T-Mobile rep didnt know this when I first called them.

Thanks, everyone, for the suggestions.

AWS after 4.4

Im running the Mod on 4.3 Jelly Bean, Stock, No Root.

[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:

[AT&T Samsung Galaxy S 4 General] Product F(RED):
Yes because OTAs usually contain a new modem (this one does for sure), and flashing anything modem related will undo the mod. Also the mod can't be done any modem newer than MF3.

[AT&T Samsung Galaxy S 4 General] Idan73:
Not quite. Since 4.2.2, through, 4.3, and now 4.4.2, the mod does not get overwritten. The only time I had to reapply patch, is the jump from 4.2.1 to 4.2.2.

Disclaimer. Never took ota, always updated firmwares with Odin.

So basically if you had patch applied, and are on at least 4.2.2, the aws should still be fine on 4.4.2. Mine is.

[AT&T Samsung Galaxy S 4 General] Product F(RED):
I have an i337 (AT&T) on a 4.3 T-Mobile-based ROM. No matter how many times I tried to update the modem, the patch has not stuck. I'm on MF3 modem with AWS mod (MK2 based ROM). I know because I can see that the phone is connecting to 1900 MHz (T-Mobile refarmed), not AWS (1700/2100 MHz).

EDIT: I see you did it via ODIN. Maybe it never stuck for me because I update the modem via zip (recovery).
[AT&T Samsung Galaxy S 4 General] Idan73:
For us, we were never able to flash modem with recovery, on sgs4. And even before, on old galaxies, it was only a partial stick (full modem flash was always possible only with Odin or with factory reset) , which in itself was good in some situations.

You shouldn't if you value your ability to Loki and use custom kernels and or recoveries, ever, due to your model locked bootloader.

If you have Loki flashable firmware, I would just go with custom firmwares like goldeneye etc. Only update modem, part 1 and 2 with odin, while rest from custom recovery.

No I don't have att model, so you should confirm with someone specific to your phone model.

Well my bootloader is locked down tight, so don't care too much about that. Losing AWS would suck a little, but it's my wife's phone so she barely uses it. At this point I might start a bounty in the T-Mobile S4 forums for a 4.4.2 QCN file. Anyone else willing to throw in a few bucks$$??
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I have no idea why it's so hard for people to make a QCN. I might just ask my friend who has a T-Mobile model if I could plug his phone into my laptop for a few minutes while I get the QCN (no promises, so don't wait on me).

Is there a benefit here for the average user? Or is this mainly for unlocked international users?

Why would was be disabled by Samsung or the carrier if this is useful?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
It's not for international users at all. It's for T-Mobile and other AWS-based carriers (carriers that use the combination of 1700/2100 MHz). This is only used in the US and Canada really on some networks. Samsung disabled it because not all carriers need it (even though yeah, they should morally enable it for the sake of having all bands enabled, like Sony does).

This mod is only for the i337 and i337M. On the M919/M919N/M919V/i9505G, it's already enabled (T-Mobile/MetroPCS/Canadian AWS variants/Google Edition). Don't flash this on ANY other model.

I'm using my AT&T S4 (got it for $300 off a dumb guy who was selling it, otherwise I would have just went with a T-Mobile model) on T-Mobile with this mod. Without this mod, I would get EDGE and LTE only (though I happen to live in a refarmed area, so I technically would get 4G/HSPA+ without the mod, though slower). This mod enables AWS (Band 4), so I get T-Mobile 4G as well.
