[Q] Urgent Cannot return to CDMA mode after international SIM usage - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hello everyone,
In the last 4 months I have been using a foreign SIM card. Last night I came home, and I cannot return to CDMA mode and resume use of my normal Sprint service. I cannot change the network type in the settings (screenshots attached)
I was told that I might need to do a complete factory reset, but honestly I would hate to do that and find out that my foreign SIM card will no longer work for some reason.
My question: Is there any way to reset the mobile network settings to Sprint factory defaults? I have a feeling that the foreign SIM modified settings unbeknownst to me.
Attachments:
In the first picture, you can see that the menu has the option to change to CDMA EVDO LTE, but once that's selected, it doesn't enact any changes. I am not able to revert to CDMA mode.
Hope you guys can help! Thanks in advance.

Another symptom:
All ##****# hidden menus no longer work.

Try *#0011# instead. It will present you with a debug screen. Press the left soft key (menu button that glows) and select "key input", type the number 1 and press OK, the press the left soft key again and select "back". Repeat this until the screen changes to a different menu. Once at the new menu press the left soft key and back one more time. You should see a selection for cdma, press that then select common. Press next page twice and on the third page there should be an option for "pref mode set", select that, then select cdma/lte (or something similar I can't remember off the top of my head), reboot the phone and you should be back to norm.
However if your phone somehow took an update when you got home from traveling and Is on mja now, you might have to to a clean wipe and odin a full modem/kernal/rom.
Let me know if this works!

Ah, regretfully, I never got in to bitcoins!
Anyways, I had another question. How do I revert to stock completely? I would like to get to the point where I can use the original dialer codes (still won't work). I do have data now, but 3434 or 3282 don't work. Also, cannot update profiles OTA/download updates. (See screenshot)
Also, what is the magic OTA that locks your phone? MJA? I'm still on MDL, but I wouldn't mind upgrading if it would benefit me at all.

Oh, I'm not out of the woods yet.
Cannot receive calls/texts, but I can make them. Also, cannot attempt to re-activate the phone, saying there's no network.

Android_Secret_Code String Revealed!

Hell yes!
After a few hours trying to uncover the dialing code string for the Fascinate, I finally figured it out!
I've dug into *almost* all the AndroidManifest.xmls to compose a list of hidden menus you can gain access to.
I shouldn't have to say it, but I will..
I'm not responsible if you brick your phone.
Play with these things at your own risk.
Even if I said it's been tested by me and confirmed to work.
It's not my fault if your phone takes a crap on you.
Make a backup of your phone.
I will be doing some more testing and will uncover more hidden menus, but this is what I have for now..
Some members of another forum where having trouble using these codes and I've discovered that you need Hiddenmenu enabled. To enable Hiddenmenu, do the following:
Go into the Dialer and enter *#83786633 then press the Home key
Go back into the phone dialer and enter *#22745927
Now a box will come up asking for the SPC code. Enter 000000
Press the Hiddenmenu Enable radio button.
Now you can use these codes.
The dialing code string you have to use is *##
Here are some things you can gain access to
Audio Tuning
*#28346#
Several audio tuning menus.
I've only tested the two items below:
To silence boot and shutdown audio go to Situation/BOOTSOUND and turn the values to 0. I've tested and confirmed this works.
To silence the volume key audio when turning the volume up/down go to Situation/VOLUMEKEY and turn the values to 0. I've tested and confirmed this works.
Full Bat Popup
*#3844228#
This allows you to disable the full battery pop-up.
I have tested this and it works successfully.
HwCodec
*#0002*28346#
Audio path volume controls. Most importantly, it looks like there's a sidetone adjustment.
I have not tested any of these items yet.
Shutdown
*#7594#
This enables you to shut your phone off by long-pressing the power/lock key.
No more pop-up confirmation.
I have tested this and it works successfully.
I also need to point out that this disables your slide lock screen.
Diag/Testing Mode
*#4636*1111#
Does this allow us to change intricate GPS settings, ala the "GPS fixes" for the earlier Galaxy S models?
Or is that not an issue with the Fascinate?

This isn't working for me. Nothing happens after I do this.
I enter the first string, press home, press dialer, the first string is still there and I enter the second string. Nothing happens.

You can gain access to a GPSSetup menu using this short code-
*#1472365#
The settings are set to the "fixed" values by default.
You don't need to change anything.
You can go into Command and then start GPS and force a satellite lock.
There's other cool info there too.

After pressing Home and entering back into the dialing, clear the first code and enter the second.
I will update the directions to include that.

awesome that you figured out how to enable secret menus...now how do we enter into diag mode? i wonder what code that is. i tried 8778 but that didnt work out
*#7594#
If your enable this, it appears to not only shutdown your phone with a long press of the power key, but it also disables your lock screen (puzzle/glass screen).

The proper spelling is "dummies. " Using an apostrophe-s shows ownership. Dummy.

It looks like the message goes away, but the screen still turns on when the battery is full. I love how bright the screen is, but even at the lowest setting this phone can light up an entire room.
Thank you SO much for including the "disable battery full popup". That thing was annoying as HELL!
Bummer that it turns on the screen, still. Also, I agree that the screen is extremely bright, even with "night mode" in the Desk Cradle app. I'd like it if I could decrease the "minimum brightness" value even more, so I could use this phone + cradle as my alarm clock replacement.
Way to go egg_head!

How disable Full bat. notification!

I found this on
sefanboy.com/2010/10/11/samsung-fascinate-hidden-secret-codes/
I tried it, It seems to work, I will know tonight!
Go into the Dialer and enter *#83786633 then press the Home key
Go back into the phone dialer (clear first code) and enter *#22745927
Now a box will come up asking for the SPC code. Enter 000000
Press the Hiddenmenu Enable radio button.
Go back to the phone and dail
*#3844228#
Click the box that says Disable Full Battery Notification.
done and done
That's been around for quite a while, and most people still get the pop up
Sent from my SCH-I500 using XDA App
Doesn't work on DL30. The hidden menu will enable but the audio and disable full Bat menus will not show up. The codes probably got changed for DL30.
The last time the codes worked for me was DI01, the changes I made wouldn't stick on 05/09.
Haven't seen if anyone has found the new menu codes for DL30.
Any devs have luck or any ideas were I could start I have looked in sys files no luck

How do I find the IMEI on CDMA Wildfire ?

I have a Unicel HTC Wildfire CDMA that I would like to unlock, but for the love of ...you know who, I cannot find the IMEI.
Not under battery, not with *#06#, not under Menu Settings, etc.
I even tried ##786# and enter service mode....nothing.
Anybody can shed some info ?
Thanks
Open the dialer and press *#*#4636#*#*
Wait for a menu to pop up and choose phone information, it should be right at the top of
the screen.

[Q] Having a problem with the free unlock . Service Mode: Limited

Hey I am having an issue with the free unlock for my Fido S4 running 4.2.2 . It isn't rooted to my knowledge but when I go through the first step of dialing the *#0011# And theni press menu back, menu key input 1, then press menu back... I don't get booted into the UMTS Main Menu. Nothing happens. I did look at the screen shots for the free unlock guide and i think the main difference in where is says service mine says 'Service: Limited" instead of "Service :Active" . Has anyone else run into this problem? Or does anyone know why my phone would say "Service: Limited"?
Here is a screen shot. Thanks in advance.

UK Galaxy note 3 - Sim Network Locked - Help

Hi
i bought a used Galaxy note 3 on ebay UK as the seller said that it was unlocked to any network
i am originally from UK but now live in Czech republic
so when the phone arrived i put my cz sim card into it and the phone has a grey screen asking me for a sim network code
i took the phone to a local service which can unlock phones - but the people said that they could not unlock the phone
as it has UK software on it and their methods they were unable to get the code ..
i tried to flash a CZ official rom onto the phone but it did not seem to work well on the phone..
unable to do any software updates - as it did not allow
can anybody recommend a place in London to take this phone to get it unlocked
or i have seem some web based services which offer to send a network code when you make payment
but i was unsure about this web based service method
right now the phone is useless to me until i can get it unlocked
no help either from the seller..
so i hope someone on here can point me in the right direction
thanks a lot
I m interessed too
