Has anybody found a work around for the "application was not installed" when people try to install phoneutil.apk? I have checked the box to install from unknown sources, restarted the phone, tried various file explorers and still no luck. I googled everywhere and I have found no luck. It seems like people try to troubleshoot and just give up. I am running PAC MAN rom.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Well you can just replace the built in APK with a root capable file Explorer (like Solid Explorer or ES Explorer). Just go into /system/app/ and replace the APK and reboot. I had no problem just installing the APK though. WICKED ROM.

[AT&T Samsung Galaxy S 4 General] jmarsh24:
I moved the phoneutil.apk file into the system/apps/ folder and when I input the mmi code it says that it is invalid. I'm guessing this means the phoneutil.apk was not installed.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You replaced the original one? Because if there was no phoneutil.apk in there before, it wasn't the right directory. Like I said, for me it just straight up installed.
[AT&T Samsung Galaxy S 4 General] jmarsh24:
No there was no phoneutil.apk in the folder because when I try to install the apk, it says that it was unable to install. I'm am completely clueless as to why it wont install.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Did you enable sideloading?
[AT&T Samsung Galaxy S 4 General] jmarsh24:
By sideloading do you mean allowing installation from unknown sources? If so then yes.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Yeah, that's what I meant. Hmm. Then I'm not really sure. You need to find out where phoneutil.apk is installed to by default and just replace it. It's a system app.

i'm just a little confused with all the model numbers and frequencies so i'll ask this in simple terms.

Can i use a rogers s4 on wind after unlocking it and applying this mod?
[AT&T Samsung Galaxy S 4 General] neysito:
Yes, you can use it. In fact I have been using one with mobilicity since almost a year now. Just remember you will not get lte with Wind, just hspa+.

GS4-I337M
[AT&T Samsung Galaxy S 4 General] ericl619:
thanks. if i may also ask, after adding this aws mod, will my s4 be considered pentaband where it can be used with almost any carrier?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Yup. It basically becomes a T-Mobile S4 in terms of supported frequencies (at least in terms of HSPA+).

You guys in Canada use a combination of US and European LTE frequencies. AT&T uses 700 MHz (not used in Canada I think), and T-Mobile uses AWS for LTE. Rogers uses I think 800 MHz and 2600 MHz (neither used here). Though some carriers you use like Wind use AWS for LTE I believe. Both AT&T and T-Mobile devices support the same frequencies. AT&T is just an assh*le and asks manufacturers to turn off AWS for HSPA+ since only T-Mobile uses it. If you're wondering why they don't Alps disable AWS LTE, it's because they themselves use it in a few areas.

I think it's called Pay Your Way or something? $40 gets you 6 months. Free incoming calls and unlimited text/pic/vid :)

(P.S. Rogers also has a similar deal for $85/yr).
[AT&T Samsung Galaxy S 4 General] ericl619:
Oh it looks like it doesn't include data and is that a promo? Because all I see is the 10/month of expiry at .20/min. Or maybe it's different in GVA. Yes please send me a link if it still exist, I am gonna transfer another line over to them
[AT&T Samsung Galaxy S 4 General] toysareforboys:
Yep, no data included, I just use WiFi everywhere for my phone.

It's the plan on the left: http://www2.windmobile.ca/en/Pages/voice-plans.aspx

$0/mo with the $5/mo add-on. Wind has a thing called "service life" where if you spend $40 you get 6 months, then the suck the $5 out of it every month, that's where I get the $6/mo from :)

[AT&T Samsung Galaxy S 4 General] Product F(RED):
Oh, dude, PacmanROM is an AOSP ROM? If I'd know that I could have told you from the beginning that you have to be on a Samsung based ROM.

Woah. Well the phone supports 700/850/1700/1900/2100 MHz LTE, but it does not support 800 MHz...That's really weird.

When that happens again, can you please go into the dialer and dial:

*#27663368378#

Then choose [1] UMTS -> [1] Debug Screen -> [1] Basic Information, and please post the screenshot here. It will tell us what frequency exactly is being used.

Oh, dude, PacmanROM is an AOSP ROM? If I'd know that I could have told you from the beginning that you have to be on a Samsung based ROM.

Yep! Pacman ROM is a AOSP ROM. lol. I guess instead of just saying the rom I should specify if its a samsung or AOSP rom next time! Well at least the issue has been solved. I know various other people have had the same problem in the forums. It should be added to the original post to troubleshoot.
[AT&T Samsung Galaxy S 4 General] att85:
Hi

now here are some screenshots. I had to use the *#0011# since your code doesnt work on my firmware.

1st pic with the "4G" icon.

2nd pic with "4G LTE" icon.

3nd pic some speed measures:

The first 2 measures were with "4G LTE" icon (with 3-4 barsbars)

The 4th measure is with the "4G LTE" icon, (with 2 bars)

The 3rd measure was with wifi, ignore that.

Does this help you?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Yes. Ok so, on "4G" (meaning 3G or HSPA+, because our stupid carriers brand it as "4G"), you're on 2100 MHz (Band 1). On LTE, you're on 2600 MHz (Band 7).

I got the information for LTE from here (just search for Vodafone Germany): http://en.wikipedia.org/wiki/List_of_LTE_networks

Holy sh*t! That means our phone supports 2600 MHz by default and our carrier is hiding it from us! I'm not surprised at all; AT&T is super sneaky. Wow, this is crazy. Thanks so much for providing that information. For all we know it also supports 800 MHz, but since in your area they're using 2600 MHz (I'm assuming you're in a city, not rural area), we won't know.
[AT&T Samsung Galaxy S 4 General] att85:
I took the screenshots in Stuttgart (pretty big city). So I ssume it's 2600Mhz. Anyway, Vodafone uses afaik also 800 Mhz in rural areas. I will keep on tracking

Maybe the 2600Mhz support works just with a foreign sim?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Well in the US, 2600 MHz is not used. However, it is in Canada. I believe it's there for the sake of business users who need fast data when traveling, but it's not advertised to the general public in order to prevent reselling overseas. I know for a fact that it does not support 800 MHz, but if you could prove me wrong, that would be nice.

I have family in Stuttgart, by the way, though I myself have only been to Berlin and Frankfurt (and Vienna, next door in Austria) :) Frankfurt airport was a maze, I'll never forget. Navigating it was hell :P

MF3

Damn, I went through the process and got AWS working, but then flashed a mf3 and it reverted the changes.

Will this work with MF3 modem, or do I have to use the MDL modem?

For some reason my work wifi doesn't work with MDL on MF3

MF3 also tends to give me better battery life.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You can do the mod again. The wifi thing is common. Look it up. I forgot the cause.

[AT&T Samsung Galaxy S 4 General] movielover76:
MF3

Yea, but the question is does it work with the MF3 modem? Using the MF3 modem is the only thing that fixed wifi for me.

I redid the hack using a mdl rom and mf3 modem and it seems to work.

Couple things I noticed

GPS issues at first

Once I clear agps and rebooted the GPS started to work again, sometimes a bit slow though.

Speed Tests with Speedtest.net app.

Upload speed test fails with network communication issues

I'll wait and see how that affects day to day operation.

This mod might not be 100% suitable for MF3 modem

After reverting to normal MF3 without AWS

GPS lock is quick

Speed Tests run fine, and speeds are quicker.

1900 Mhz HSPA+ and LTE are pretty well deployed round my area

so my choices are

MDL w/ AWS , no wifi at work, reduced battery life.

MF3 no AWS, wifi at work

and I take my chances of falling back to edge more often.

In my immediate area of NJ LTE and 1900 HSPA+ seems solid

but who knows what will happen if I travel :(

UPDATE

Seems you can fix the problems the hack causes on mf3 by reflashing the normal mf3 modem

after reflashing mf3 normal over my hacked mf3, the aws unlock stuck.

flashing mf3 over mdl w/ hack had removed the fix, so I assumed it would be the same

But *#2263# and *#0011# confirmed I can still force my phone to AWS

without any of the issues that I had immediately after hacking the mf3 modem.

Sorry to be so long winded, just hoping to save someone else some time

trying this, information on this hack + MF3 isn't very common.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Hacked MF3? What are you talking about? Also, the MDL w/AWS modem is a scam; it's exactly the same as an MDL modem; I compared the files myself. You have to do this mod on any modem (also if you flash or reflash the same or another one).
[AT&T Samsung Galaxy S 4 General] movielover76:
Hacked

Yeah, I know you have to do the mod yourself, I tried the hacked modem listed in the modem list and learned for myself it doesn't work.

I should have been more specific.

I flashed the stock normal MF3 modem after enabling AWS on the stock MF3 modem.

And unlike when you flash a new modem, for instance MDL to MF3

the AWS unlock stuck, and fixed the issues that I found with MF3 immediately after unlocking AWS.

I tested everything I posted by locking the phone to specific frequencies and confirming the frequency I was on

with *#2263# to lock the WCDMA frequency , or choose automatic for LTE

and *#0011# to check that it properly connected to the selected band.

I spent over 4 hours on this today because MF3 works so much better for me in general.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
That's interesting. AT&T modems specifically disable and will re-disable AWS for HSPA+ if you flash them [again]. So it's cool that you managed to get it to stick.
[AT&T Samsung Galaxy S 4 General] movielover76:
Flash MF3

I used the auto loki version of CWM, I don't know if the tool used to flash the modem matters or not.

When I flashed MF3 over MDL (that I had enabled AWS on) it did re-disable AWS

Maybe it only disables AWS if you're flashing a different modem?

At least in the case of MF3

[AT&T Samsung Galaxy S 4 General] AJ Newkirk:
I did this on my friends 337 while it had the MDL modem , but since he does not have a T-mobile sim all I could verify was that T-mobile was listed in Available Networks. I flashed the MF3 modem some time afterwards and it still had T-mobile listed in Available Networks. Is this an indication that AWS is working properly, or is there some way that I can check/verify without having a T-mobile sim?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
T-Mobile runs 1900 MHz in some areas (which non-AWS devices will pick up), so it's possible he's in one of those areas. Flashing a new modem undoes the mod anyways.

Modem found here: http://xdaforums.com/showthread.php?t=2496517

I attempted the mod and when restoring it gets to 5% followed by an error of "invalid command to phone" I believe that was it. Perhaps we need a new QCN backup from a T-mobile phone running a new 4.3 MODEM to get the new NV structure for 4.3 modems.
