How To: Enable LTE without ROOT/FLASH (model: SM-N900W8)

It's been awhile since I was on the forum but thought I would create a quick post for those who wish to enable LTE on the Samsung Galaxy Note 3 (model: SM-N900W8) where LTE has been crippled. I have compiled the following steps and this should get you up and running without having to ROOT your device, install RECOVERY software or FLASH a new modem.
1) Obtain the device IMEI by pressing *#06# on your dial pad and record this number to reference later.
2) Type in *#272*[IMEI Number]# Where [IMEI Number] is the number you recorded in the step above.
3) You will be prompted with a 3 letter "Regional Settings" menu. Cross reference the 3 letter code with the carrier list at the following link: http://www.samsungis.com/Firmwares/SM-N900W8.html. You do so by hovering over the 3 letter code under the "Region" column. If the SIM you wish to use is from one of these carriers and the carrier supports LTE, we're on our way! The above steps are confirmation, do not modify anything yet!
4) Unlock your device using a preferred unlocking method. Myself, I use http://www.cellunlocker.net which charges $32.99 US for a Samsung Galaxy Note 3 unlock code. It's a reliable site with quick turn-around.
5) Once you receive your unlock code, put in the SIM from the carrier you wish to use and enter the unlock code when prompted.
6) Once unlocked, it may reboot and when at the main menu, follow step 2 and 3 above but this time, select your 3 letter carrier code for the carrier SIM you just inserted then click on OK or INSTALL.
The device will go through a boot up sequence but once complete, you will have LTE enabled. If you do not see this, go into your network settings and you should have the option to select GSM/WCDMA/LTE (auto connect).
Hope this helps those of you wishing to enable the crippled LTE band but do not wish to delve into all the technical jargon related to ROOTING, RECOVERY and FLASHING.

Thanks for this.

Thanks
Thank you for sharing this wonderful trick. I was looking for something like this for a long time.

Please be noted that the secret code *#272*[IMEI Number]# does not exist in many recent models.
You can use Phone INFO ★Samsung★ app > Menu > 'Secret Codes' to check if this code does exist.

THIS WILL ERASE YOUR PHONE...
But it works...

[How To] Write a PRL to V20

WARNING I AM NOT RESPONSIBLE FOR WHAT YOU DO TO YOUR DEVICE
MESSING WITH NV ITEMS CAN CAUSE SERIOUS DAMAGE TO YOUR HANDSET
USING THIS TOOL/INFO TO BREAK THE LAW IS NOT CONDONED
USING THIS TO VIOLATE YOUR CARRIERS TERMS IS NOT CONDONED
I WILL NOT HELP WITH WRITING ANYTHING TO YOUR DEVICE OTHER THEN A PRL
I DO NOT PROVIDE ANY LINKS TO THE PRL OR TOOLS USED. USE GOOGLE SEARCH BOLD ITEMS + XDA BELOW!
1. LG Drivers installed, Diag drivers specifically
2. MSL for your phone
3. QPST installed ( 2.7 or newer preferred )
4. SPRINT/VZW PRL file of your choice ( Sprint is on 54xxx) Universal sprint VZW is 00001 00002 etc, be careful as those can piss off your carrier!
Step 1 - Install your LG drivers and acquire your MSL from sprint.
Step 2 - Google and install QPST.
Step 3 - Find what PRL you want to use and put it in a folder on your computer.
Step 4 - Turn off USB debugging on your phone...go to settings > applications > development > uncheck USB debugging
Step 5 - Open the dialer on your phone and enter ##3424# Turn Diag ON
Step 6 - Connect your phone to the computer and select Charging only if prompted.
Step 7 - Open QPST Configuration wherever you installed it.
Step 8 - Click on "Add new port"
Step 9 - UN-Check "Select Serial and USB/Diagnostic Ports Only"
Step 10 - Select your phone on the list and hit OK.
Step 11 - Select your phone on the list.
Step 12 - Click on the "Start Clients" tab at the top and select "Service Programming"
Step 13 - Select your phone on the list and hit OK
Step 14 - Click on "Read from Phone' in the bottom left
Step 15 - Enter your MSL when prompted and hit OK
Step 16 - Click on the "Roam" tab then click "Browse" and navigate to your PRL file. After selecting your PRL click "Write to Phone".
Step 17 - Your phone will reboot at this point and you will see a couple popups on your computer that you can just hit OK to close. Let your phone reboot and don't close QPST until it is finished writing to your phone.
Step 18 - The PRL should be written to your phone now. You can verify it by going to settings > General > About Phone > Status
Once back on sprint prl, you should be able to UPDATE prl and get it to update to the one for your act/area!
Pleas feel free to post results or if you had to do something different!

This is also another option, but i haven't found a way to get it to locate a prl and write it.
maybe some oter people can figure out how to get this to work from the handset?
Ive tried running in production mode, in dev mode, made changes from user to debug and dev in the build.prop
but its still a blank screen when you try it.
using quick setting app you can search ( SPRO ) and click the 1st entry. This isn't for new users so stay outta this stuff lol!
the full entry is com.lge.lgdmsclient.ui.test.SPROmadmHiddenMenuForSprint
in a nutshell it would be exploiting a prl write test to get it to actually write a dif. prl

Verified that Cmda Workshop Trail will write the prl also, it wasn't mentioned in op due to it is NOT FREE, and will require a purchase after 30 days.

You sir are a boss

verizon users are stuck as usual

Enable VoLTE & Enhanced Messaging on Samsung Galaxy Note 8 and Note 9 Exynos [solved]

Enable VoLTE & Enhanced Messaging on Samsung Galaxy Note 8 and Note 9 Exynos [solved]
If you have a Samsung Galaxy Note 8 and Note 9 International Version with the Exynos CPU, you might have an issue enabling VoLTE and Advanced Calling & Messaging. After weeks of searching, I figured out how to fix this.
In a nutshell, using Odin you can flash the Germany DTM firmware onto your device, this release contains Advanced Calling & Messaging.
How to do it:
Enable OEM Unlock on your phone in the developer menu.
Go to sammobile and find your firmware, Look for "Germany DTM (T-mobile)" I realized that t-mobile contains the system and modem settings we need. It doesn't matter if you have something else like At&t. we just need the t-mobile modem and system and bootloader.
Download Odin v3.13.1 from sammobile as well, unless you already have it.
Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
Add each file to it's respective field in Odin v3.13.1.
Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
I used HOME_CSC, this preserved all my apps and settings. and did not install T-Mobile bloatware at all.
Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + BIXBY
Other options in case first option did not work or isn't possible.
Option 2 VOLUME DOWN + VOLUME UP than USB cable
Option 3 POWER + VOLUME DOWN + VOLUME UP
Option 4 POWER + VOLUME DOWN + HOME BUTTON
Option 5 (Note9) USB cable + VOLUME DOWN + BIXBY
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC! - you can install Kies and it will install the drivers)
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC.
Your phone should reboot and configure itself, the next step is to open "More Connection Settings" and enable Advanced Calling & Messaging. This will enable LTE and you should see the new LTE icon in your status bar. You should be able to now browse the web at LTE speed while on a phone call. and you should be able to make video calls (although I don't have anyone to call, to test it)
If you need the "Wifi-Calling" you will need to t-mobile apps.
[UPDATE]
INS or the INDIA version firmware seems to support VOLTE as well, trying that next. Might have more luck with this one.

What about samsung pay and secure folder?

[GUIDE] Enable 4g+/LTE-A Carrier Aggregation without Root on Stock Rom

As we all know, MiA1 has a Snapdragon 625 processor that comes with the X9 LTE modem which supports Carrier Aggregation (2CA) but the OEM has not enabled it.
With the help of this guide you can enable carrier aggregation in your mia1 even without unlocked bootloader and root access.
Tools Required
1. Minimal ADB Drivers
2. QPST Flash Tools
3. QxDM Professional
4. LTE Band Calculator for Android
Steps to Follow
1. Install Minimal ADB Drivers, QPST Flash Tool & QXDM Professional on your PC.
2. Enable USB Debugging on your MiA1 .
3. Go to Phone dialer and dial " *#*#717717#*#* " to enable Diagnostic Mode(See Update Section below before Proceeding).
4. Connect your phone to PC via USB Cable then your PC will detect the device and automatically install the drivers.
5. Open Device Manager on PC and look for Ports(COM & LPT), under this you will see your device listed as "Qualcomm HS USB Diagnostics 9091 (COM*)".
6. Now, Run QPST as an administrator then goto Ports tab and check if your device is listed there and it's state is enabled.
7. Run QXDM as an administrator then goto Options tab and click on Communications. Now a new window will open, in that select your device COM Port under "Target Port" and make sure that your device is selected under "PortType", then click OK.
8. Select "NV Browser" from drop-down menu under View and select "RF LTE" under Category Filter.Now scroll and find something like "RFNV LTE B* CA BC CONFIG"("*" denotes the band).
9. As MiA1 only supports 2CA. we can CA using only two bands
For Ex: B1+B3, B3+B5, B3+B40, B5+B40, B5+B5, B40+B40 etc..
You can select any two band combination that is supported by your carrier and is available in you region.
10. Now Open LTE band Calculator on your phone and select two bands (e.g. B3+B40). you will see a value like "549755813892" or something else(it depends on your bands selection).
11. In QXDM select "RFNV LTE B3 CA BC CONFIG", click on "Read" then double-click on Input and clear the default value "0" and type the value that we have calculated using LTE Band Calculator in step 10 above, then click on "Write". Now,do the same with "RFNV LTE B40 CA BC CONFIG".
12. Wait for few seconds and then disconnect the phone from PC.
13. Now,Restart your phone and turn on data you will see 4g+ icon in status bar. That's it.
Things to Remember
* In step 10 choose bands that are available in your region and make sure, that your carrier supports CA over that bands.
* In step 11, change the value of bands selected in step 10.
* You have to try and test multiple combinations to get the stable CA state because in some bands network is unstable.
* If you lose signal after this process or if you want to revert back then just repeat step 11 and put default input value which is "0" for MiA1.
To check whether CA is working or not
1. Open Phone Dialer and dial "*#*#4636#*#*" to enter in Testing menu.
2. Tap on Phone Information and check "LTE physical channel configuration".
If CA is working, It will show you two connections Primary and Secondary along with their bandwidth, otherwise nothing.
I have configured intra-band CA over band 40 on Jio4G.
You can look at the screenshots attached below for difference with or without CA.
Update
USSD code is now working on latest June 2019 Security Patch.
USSD code is not working on March/April/May 2019 security patch.
If the USSD code doesn't work then you have to root your device first to enable diagnostic mode and after that, you can proceed further from step 5.
There are two ways to enable diagnostic mode after root which are as follows:
1. ADB
Enable "USB Debugging"on your phone.
Connect it to your PC/Laptop.
Open "Minimal ADB & Fastboot" Command Prompt with administrative rights.
Type adb devices and press enter.
Type adb shell and press enter.
Type su and press enter.
Type setprop sys.usb.config diag,adb and press enter.
2. Terminal Emulator App
Install any "Terminal Emulator" app from play store e.g. Termux
Enable "USB Debugging"on your phone.
Connect it to your PC/Laptop.
Open "Termux" .
Type su and press enter.
Type setprop sys.usb.config diag,adb and press enter.

Thanks for good guide. is there any root way to this process easier?

I am using Airtel, I want to enable 4G+ but my bootloader is locked. So, can I do this? After doing this, will I face any problems in OTA because of new firmware and modem with upcoming updates and any random reboots will happen?

How To Guide How to enable VOLTE and VoWifi on Realme GT Neo 2 (and probably other Realme devices) when the toggles are not available in SIM info & settings

This post records how I combine many tutorials online and finally enable VOLTE and VoWifi on my Realme GT Neo 2 while the toggles are not available at the beginning.
TLDR: Most Realme devices support VOLTE and VoWifi, but the toggles may not be available in countries where Realme is not sold officially. However, they could be enabled by editing the build.prop file. Root and Magisk are necessary. Using Magisk, services like Google Pay can still work properly (price is potentially less security).
As we all know, most Realme devices support VOLTE and VoWifi, and usually you can find and activate them easily in Settings->Mobile network->SIM-> SIM info & settings. There are many tutorials on the website. However, in countries where Realme is not sold officially, you may not find these 2 toggles. I'm not sure about the exact reason but some are saying that local operators have strict whitelist policy (like ATT and TMobile), and of course a device sold only overseas won't be on it.
My situation​I bought a Chinese version Realme GT Neo 2 and the bands are compatible with Tmobile 4G (link). After getting the phone, I refer to this post to flash the global version firmware. My operator is Mint, a mvno of Tmobile and I cannot find VOLTE or VoWifi toggles. After reading this post and using an app called ForceLTE, I'm able to use 4G data. But whenever I make a phone call, the signal jumps back to 3G and data becomes H+(HSDPA). Recently Mint sent me a message, saying that they are retiring 3G soon and my device is not compatible. After a certain date, my phone will not be able to make/receive phone calls if still relying on 3G.
IMEM check fails on Tmobile, Mint, and ATT websites.
On Xiaomi devices there's a code used to activate VOLTE directly, on Oneplus devices you can use log app, but no similar way can be found for Realme devices.
This method I find could be applied to other Realme devices in other countries when the toggles are not available in SIM info & settings.
Disclaimer​Please try the posts I mentioned first.
This method requires root. Take your own risk for any of your behaviors.
I'm not responsible for any of your losses (including, but not limited to device, finance, data, personal info)
Device info​Realme GT Neo 2 chinese version
Global version firmware (RMX3370_11_C.02) via TWRP
Bootloader locked after flashing the firmware
Steps​1. Unlock the bootloader (refer to this post). Attention: unlock will get all data wiped!
2. Install TWRP (refer to this post) and Magisk (refer to this post).
Attention: even after you flash TWRP.img to the recovery partition, if you keep using stock firmware (no matter what region/version), recovery will go back to stock one after the first time you boot to the system. You'll have to install Magisk (or use 3rd party firmware) to keep TWRP
3. Install MagiskHide props config (refer to this post) to allow us to edit the build.prop file. It is in system partition (ext4, read-only), and can no longer be edited directly (even if you try to remount it in TWRP or ZArchiver with -rw).
4. Install a terminal emulator from google playstore. Android is a linux system, imagine this app as a window you can open on your PC with linux to input commands.
5. In the emulator,
5.1 type "su" and enter
5.2 type "props" and enter
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
5.3 type "5" and enter (Add/edit custom props)
5.4 type "n" and enter (New custom prop)
5.5 type "persist.dbg.ims_volte_enable" and enter (the prop we want to add)
5.6 type "1" and enter (enter your desired option)
5.7 type "y" and enter (Enter y(es), n(o), e(xit) or an option from above)
5.8 type "n" and enter (do you want to reboot now)
5.9 repeat step 5.3-5.8 for the following props:
persist.dbg.ims_volte_enable, type "1" in step 5.6
persist.dbg.volte_avail_ovr, type "1" in step 5.6
persist.dbg.vt_avail_ovr, type "1" in step 5.6
persist.dbg.wfc_avail_ovr, type "1" in step 5.6
persist.radio.rat_on, type "combine" in step 5.6
persist.radio.data_ltd_sys_ind, type "1" in step 5.6
persist.radio.data_con_rprt, type "1" in step 5.6
persist.radio.calls.on.ims, type "1" in step 5.6
In step 5.8 after you finish entering the last prop, type "y" and enter (reboot now)
6. After reboot, check whether 2 toggles are there in Settings->Mobile network->SIM-> SIM info & settings
7. If you still want to properly use apps like Google Pay after root, refer to this post
Test if VOLTE and 4G network work​1. In settings->Notifications & status bar->Status icons, make sure you turn on VoLTE, VoWiFi and Mobile network
2. If you are connected to a wifi and VoWifi works, you should see a small wifi sign above telephone sign in status bar, like this
In addition, for Tmobile, in Settings->Mobile network->SIM1, the Carrier is shown as T-Mobile Wi-Fi Calling (for mvno like mint, don't forget to turn it on on mint website->personal settings first).
3. Disconnect the wifi, you should see "4G" above the network sign, as well as VoLTE sign in the status bar. Turn on data, make a phone call (such as voicemail), minimize the window, check if "4G" sign is still there. Finally, with the call going on, try openning a website like Google. If "4G" sign is there during the whole process, congratulations!
Let me know if this works for you, or if you have any questions/suggestions. Thanks!

Worked for me thanks. Couldn't get volte registered on network. But I now have my toggles.

Hi, thanks for the reply and it's good to hear that. I just updated the steps to check VoWifi and VoLTE, do they work for you? If not, try this post (developer options + ForceLTE) and reboot.

No my ims status is not registered. I spoke with my isp telus. Basically device not on list I won't get volte to work. So guessing the only option is some sort of spoofing.

Please do not give up hope. Using MagiskHide props you can even change your device name (RMX3370). Probably one plus device would be a good choice to fake.

GOOD JOB! I have a rmx3366, Realme GT Explorer Master Edition with the original chinese version firmware(RMX3366_11_A.16), realme UI v2.0. Do you think I can follow your steps without flashing the global version firmware?
I will be ready to go with Tmobile 2g for voice/text otherwise.

Yes I believe the method should work for most Realme devices, even with UI 2.0.
If you have your bootloader unlocked, feel free to give it a try without flashing global firmware. All properties you set in MagiskHide props config are reversible. Start from step 2.
If your bootloader is still locked, the unlocking process will wipe all data anyway (for personal info security). For a better chance, I suggest to flash the global firmware. I'm not sure whether Chinese version firmware has any restriction (software side) on specific 4G bands used by carrier in US/other countries.

It is helpful! Thank you! My phone does not have a global version, but it works well with Tmobile so far except the volte part. I will try on the Chinese stock firmware.

Did you do step 5? I didn't see "(active)" behind your "5 - Add/edit custom props". So basically, these props are not added to magisk successfully. In addition, in your screenshot I see 5G signal available. If that's the case there's really no need to worry about 4G VOLTE.

Maybe check firmware starting with C and RUI3 then. Sorry I cannot provide a solid solution.

As I said, somehow these custom props are not added to your Magisk successfully, as 5 is not active in your screenshot.

I haven't done any of the steps, but the weird thing is, is VoLTE enabled by default?
I use Google Phone instead of built-in call app, and it shows HD next to the numbers. Does it mean VoLTE is enabled?
My model is RMX3370, Chinese version, running Realme UI 3.0, RMX3370_11_C.08

Not necessarily. The best way to check is if you are on a call check if you can still access the internet using mobile data. Without VoLTE, the modem shifts to 3G/2G, and you can't use mobile data simultaneously.

Hey XDA,
I felt obliged to contribute since the following steps worked for me and I got VoLTE and WiFi Calling switches in settings in my Realme GT Neo 2 global version RMX3370 that is on Freedom Mobile in Canada.
All factory, no root required, no bootloader unlock required.
May work on other Realme models.
Source: https://realme-gadgetlife.net/how-to-enable-volte/ (in Japanese, I used Google Translate). I can't remember where I found this link, all credits go to where they are due.
Steps, check pictures in the above link:
1. Enable Developers Options and USB Debugging (search online if needed)
2. Connect your phone to a Windows laptop
3. On the phone choose connection type Transfer files / Android Auto
(first time you will be prompted on your phone if you want to allow USB connection from this PC, choose Yes)
4. On the laptop install platform tools, open a command prompt and change directory to where they are installed
5. Enter command "adb devices"
6. The output should say:
List of devices attached
<your realme serial number> device
7. Enter command: "adb reboot fastboot"
8. The phone will enter the fastboot mode and display language selector. No need to do anything on the phone.
9. Enter command: "fastboot reboot recovery"
10. Nothing changes on the phone, no need to touch it this time either
11. Enter command: "adb devices"
12. The output will be:
List of devices attached
<your realme serial number> recovery
Here I installed realme Software&Driver Update tool from
Software Update - realme (India)
Update the latest software version on your realme phone.
www.realme.com
This may help if you're having issues at this step.
13. Enter the commands listed below ONE BY ONE. For some reason they didn't work when I entered them all together.
adb shell setprop persist.data.iwlan.enable true
adb shell setprop persist.dbg.ims_volte_enable 1
adb shell setprop persist.dbg.volte_avail_ovr 1
adb shell setprop persist.dbg.vt_avail_ovr 1
adb shell setprop persist.dbg.wfc_avail_ovr 1
adb shell setprop persist.radio.rat_on combine
adb shell setprop persist.radio.data_ltd_sys_ind 1
adb shell setprop persist.radio.data_con_rprt 1
adb shell setprop persist.radio.calls.on.ims 1
adb shell setprop persist.data.iwlan 1
adb shell setprop persist.data.iwlan.ipsec.ap 1
adb shell setprop persist.radio.volte.dan_support true
adb shell setprop persist.radio.VT_ENABLE 1
adb shell setprop persist.sys.cust.lte_config true
adb shell setprop persist.rcs.supported 1
adb reboot
14. The phone reboots and the VoLTE and WiFi Calling switches are there in Settings - Mobile Networks - <SIM> !
Note that I am not saying that your phone will display VoLTE or VoWiFi in the notification area but at least the switches (options) become available in settings
