Need help to add LTE band 3 and 7 on tmobile version - Galaxy Tab 3 Q&A, Help & Troubleshooting

was able to put the tablet into diagnostic mode by doing this:
going to calculator app then typing (+30012012732+ this opens a small number keyboard then typing *#0808# gets you to the usb menu.
managed to change NV values but it didn't add additional bands.
does anyone have an opinion on how to make the changes take effect?
Thanks

did you flash with sprint files? (this is not a rhetorical suggestion but a question)

[Q] Network settings

Hi all developers! I have one question - have anyone information about where home network information placed? As I see radio settings is independent from ROM settings. Also I see that some settings placed in ROM, for example Call section's NBPCD and Assisted Dialing settings. Problem is that I use Incredible outside from U.S. and some programs wouldn't work fine because it have some limitations in US - for example new Skype work only in WiFi mode. Then I try to run it in 3G network it's write attention like "In the United States you can only make Skype calls over WiFi". Can we fix it?
P.S. changing NBPCD and Assisted Dialing settings give result only for call making process, not for global network settings.
P.P.S. I found one way - we can change file build.prop in ROM image (system/build.prop). There is two sections - ro.cdma.home.operator.numeric and ro.cdma.home.operator.alpha. I change it to my operator's default settings and bingo, I have stock Skype.apk, that work in 3G network. Next step is change stock's backup image. So, have anybody information about OS files, where this information placed?
Last update - simplest way for change build.prop at installed image is SDK's adb pull and adb push commands use. It's checked and really worked.

I thought I had read somewhere that verizon is letting Skype work over 3G. If I can find it again, I'll post it here.
Found a hacked APK over at DroidForums. I'll try to post the link.

[Q] Easy way to switch bands? Lock to GSM or WCDMA only?

On my Touch Pro 2, if I want to lock to WCDMA only, I have to execute the following steps..
start/settings/communications/phone/[network tab]Select "GSM/UMTS Only"/[GSM/UMTS Services tab] Band/Get Settings button/ then..
Select Your Network type and from the drop down select WCDMA.
Even switching to CDMA only mode requires a lot of steps.
Whew! That's a lot. I tried to write a little program to do this in C# for windows mobile, but I got stuck because the RIL interface has no op select mode for WCDMA. (Unless it's undocumented...)
Is it possible to have a "one touch solution" for all my bands in some sort of script so I don't have to navigate that ridiculous menu? Or does someone have a programmatic way to do this?

Is there an LTE 'OFF' option? Connectivity issues. Warranty Claim?

So I was issued a warranty claim to return my Note 4 for a replacement due to not being able to make and receive phone calls and text messages.
The AT&T store has replaced the SIM card with NO fix to my problem so I was advised to get a replacement. My issue is that the device will be a refurbish and I don't like this option when I purchased a brand NEW one.
My question, is there an LTE on/off option somewhere? This morning I'm connecting to AT&T but it's Edge network only.
It'd be nice to solve this problem and keep my 'NEW' device instead of dealing with a refurb that may have unforeseen problems.
Is there an option in the *#0011# service menu?
Update after going into the *#0011# menu, I went into HW TEST MENU and chose Option 7 to 'NV REBUILD ALL'.
After reboot I seem to have full network functionality, even 4G LTE. So we'll see how long this lasts.
Goto Dialer then type *#*#4636#*#* then device info. Change lte/GSM to wcdma
The above update worked and has since choosing the option 'NV REBUILD ALL'.
So anyone who screws up their settings can always choose this to fix it.

That works perfectly.
Follow up question: is there a way to make a shortcut to this menu on the home screen?

I'm thinking if you add that number as a contact then you can add a quick dial shortcut to your home screen ☺
You may have to use another launcher as I'm unsure if TouchWiz has that feature.
Nova is an awesome launcher.
I'm using nova. Doesn't seem to work doing it as a shortcut to a contact. And none of the play store apps work.
Oh well, not that big of a deal to just dial it manually.

Note 7 Service Mode?

I've scoured the internet for finding out to enter the service menu on the note 7. It seems that the s7 and s7e have been figured out, but no one yet seems to have been able to actually enter the service mode the note 7.
I do know that the service mode application opens if one dials: *#0011#, but I cannot enter further into the application to change LTE bands and what not.
In past Samsung phones, one could further enter the service mode by hitting:
Menu -> back
Menu -> key input -> Q
Menu -> key input -> 0000
Wait 10 seconds
This method does NOT work on the note 7...
Now while this may be a larger issue, I cannot get AT&T LTE enabled on my device. I have the N930-FD from Singapore. This is why I'm trying to access this hidden menu.
On key input type in: Q0
And wait 10 secs.
Still not working.
While I follow the procedure, there is no response. It still display the network information.
What is the whole procedure to operate?
Did you have any finding regarding how to change LTE bands?
Does this work?

How do you set a custom APN?

I just got a brand new unlocked HTC 10 today straight from HTC.com. My cellular carrier is Red Pocket Mobile - an AT&T MVNO.
I connected the phone to WiFi and applied the system update for Nougat. I'm trying to set my APN for Red Pocket and it's forcing me to pick a carrier from a list that doesn't include Red Pocket. I select AT&T to get passed this and it allows me to add my APN settings. It won't let me actually switch to that APN though. There's a lock icon next to the AT&T settings and it doesn't seem to want me to change.
I've never seen this behavior on an Android phone before. Is this something new for Nougat? Is there something simple I'm missing here?
Thank you for any assistance
PS: See the attached screenshot. Notice that there's no radio button for me to click on next to the APN I've entered.
The answer is you have to select "US Travel SIM" from the list of carriers for it to allow you to switch APNs. Of course I figure it out minutes after asking for help.. :silly:
In my defense, it's not real obvious.
EDIT: I am so confused. I selected US Travel and input all the APN data. It doesn't allow me to select it now. It allows me to when I don't fill it out entirely though.
EDIT 2: The instructions I have from Red Pocket instruct me to set APN Type to: Default,mms,supl It seems like putting this in disallows me from using the APN for some reason. I hope it'll work without this setting.
