[Q] Help Needed: Service Mode on SM-T315 - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hello,
I have a Samsung Galagy Tab3 8.0 (SM-T315) for testing purposes. I need to connect to an LTE network that only supports "Packet Switched" data connection (no voice services). To enable PS only mode i need to go into "Service Mode". On other samsung devices i can use the code *#197328640# in the dialer but this does not work on the Tab3. I have also tried some service mode enabler apps.
Does the Tab3 use an alternative code? Or is it possible to copy the service mode app to this device?
Thanks in advance!

Please check!

[Q] No phone message in qpst com port status

Hi guys,
To enable AWS on SGH I317M Note 2 I have to use QPST software. I can't use it because QPST doesn't find phone even though in device manager it is listed as Samsung Mobile Serial Port (Com14) and has no problem. When I click "Ad Port" in QPST environment I see it as COM14-USB/QC Data Modem with "No Phone message. I tried different versions of QPST on different computers with the same result. I guess , problem is in the PhoneUtil settings (*#7284#} and ServiceMode (*#9090#} I changed to unlock the phone with Z3X box. Now it is unlocked and works properly.
To enable AWS I put the phone in debug mode, in PhoneUtil settings #*7284# I put both PDA, Qualcomm settings are set to RNDIS+DM+Modem. What else do I have to do to see my phone in QPST software? What did I do wrong that the software doesn't connect with the phone? Do I have to flash it or just change some settings in the hidden menu? How to do that?
Did anybody have this problem / How did you solve it?
Thanks
I am having this problem as well. Any one have the answer?

[Q] Need help to access UTMS screen

I have a Samsung Galaxy S4 mini GT - 19195, I try different methods, and google this phone model with secret codes to access the UTMS screen, but none of them work.
I try *#0011#, it didn't work.
I try *#9090#, it only took me to USB debug, and DBG msg on or off options.
What other codes I should use to access the UTMS screen, then access to phone control, and network unlock? Any instructions you can give me?

You could try the app "service mode shurtcut"
most of the functions only work on stock
thanks
Finally it works.
After I enter the service mode, I hit [MENU] + [BACK]; then [MENU] + [KEY INPUT] + Q; then [MENU] + [KEY INPUT] + "0000", then I enter the service menu eventually.
Thanks guys!:good:

Add GSM and LTE bands in Brazil

I've spent 3 days trying to enable GSM and LTE bands in my Swift following this guide from here. But when I try to use the QPST, the software does not recognize my device.
Does anyone knows the secret code to enter in the USB Settings? I've tried a lot of them but without success.
My steps were:
Unlock the OEM - check
Install CyanogemMOD 13 (6.0.1. Marshmallow) - check
Enable Developer Options and enable debugging and Root Access (I couldnt install SuperSU coz I got bootloop twice) - check
Access to USB Settings to change from AP to CP - uncheck
Does anybody knows how to proceed?
I'm from Brazil and I really need to add new bands to get a better signal reception for GSM and the right band for LTE (700Mhz).
Anyone?
I just need the secret code to enable the usb settings.
The problem was my carrier and not the phone.
I've changed the carrier and boom... 4G working nicely.

Unlock network bands, enable voLTE and 5G on nonsupported countries

Hi,
Other phone models can use EFS Tool, QPST tool to do all the mentioned tasks.
And some phones to do that requires rooting phone since they dont have Engineering mode, and some with Engineering mode support doesnt need rooting to use the mentioned tools for example OnePlus phone.
So my question, does LG phone also has this thing called Engineering mode? since LG wing is not supported for bootloader unlocking by LG yet.
Anyone has more experience with LG phone and perhaps the mentioned tool can shed some lights on the concern? Thanks.
Goid app. Well made
on LM-F100EMW,
1) use dialer code #*462633*#100#
2) go to Field Test > LTE Data Test > Tethering Mode, and select QMICM
3) go all the way back to first menu and go to SVC Menu> Port Check Test> Port Check Test and select enable
after that I am able to connect QPST. I used EFS explorer to fix CA-combos and carrier policy for my region/provider.
After doing your work, revert the changes to have a regular USB connection!!
for VOLTE first try to
1) make a new file or folder with name "enable_ue" (without quotes) on your phone's internal storage.
2) use dialer code #*462633*#100#
3) go to Field Test> Universal Enabler > Create New Config , enable VoLTE and confirm.
to add VOLTE indicator next to battery and signal strength on notification bar
1) use dialer code #*462633*#100#
2) go to Field Test > GPRI VoLTE/VoWiFi > IMS> select Sim Slot > Registration > VoLTE > and enable VoLTE Indication.
after all these
1) use dialer code #*462633*#100#
2) go to Field Test> IMS Settings> select Sim Slot > Test > Restart IMS process > select Yes
now you should have VoLTE enabled with notification bar indication

For volte i didnt change anything from EFS.
The changes i did in EFS was to add 5G for any carrier, because my carrier was not supported, and also to take the CA string from another phone's firmware, that my carrier has good support, and paste it where the outdated ca string was inside my wing's EFS.

I'm on T-Mobile firmware,and I have tried and no go.If you extract modem_a or modem_b from the firmware it has all the carriers listed.
Hi. I have LG wing unlocked dual sim. But not getting volte. Tried the hidden menu option. It is showing in settings but looks ims not registered. Can you tell if you were able to get Volte on LG Wing without mbn loading. Also if mbn loading is needed, what is the process and where do you find the files for LG wing Malaysia carriers that I can use. I have another Samsung phone and that is fully volte supported. Can I copy something from it?

When i go to field test and click on ims settings it is showing not supported. I formated my phone and it became like this. Before formatting it used to work and I could see ims settings. My phone I bought from a shop and the shop keeper sent it rooted. Thatd when IMS settings were working..but after I did a reset saying not supported. How to bring it back?

Where are you located and what condition is your phone in? I've got an AT&T branded phone but I'm on TMO...maybe we can switch!
When I go to field menu in my Lg Wing, I go to IMS settings, it is completely blank. Someone please help me in registering the Volte in my Lg Wing. I am already rooted by able to patch the stock boot.img using magisk. My phone came with an unlocked bootloader and its the European firmware. I am trying to use this phone in Asia (Malaysia). Surprisingly, when I got the phone from the seller, it was not enabled volte but IMS settings in field menu would also show up (unlike now when I go there and it is blank), and also surprisingly, my volte worked also but by mistake I formatted my phone and after that it never worked. I then tried to flash the stock firmware and did root, installed voenabler but nothing seems to be helping.
I even tried loading mbn files of different carriers via PDC but no help. IMS settings always stay blank and volte doesn't get activated. Such a good phone but not able to work because my carrier here only supports volte.
If someone has an interest in helping, will be great.
