RR ROM / Nougat [ROM][7.1.2_r17]Resurrection Remix-N 5.8.3 For Grand Prime[OFFICIAL][G530H-W-T-T1-FZ]
unlocked via doctorSIM (accepts code)
2 issues.
1. on every reboot prompts for sim unlock code via generic dialog box
2. no cellular service - via chat ATT activated the existing SIM w IMEI of new phone and existing sim. Went to APN area in settings and tried to manually enter ATT settings but after save said 'customization not available for this user'. Have not tried the Wifi first trick but I can enter a new APN but settings does not stick. Assume the sim setting would be auto configured.
TIA
I havent figured out a root strategy quite yet but i am working on it. i do believe there is a way to unlock the bootloader and make it possible to flash custom recovery. I am just missing a few key things in regards to the Hidden Menus dialer codes. If you all could check it out and tell me if you find anything useful please let me know thanks.
Here is a list of the Hidden Menu Dialer codes i have found that work most with description. (some i am unsure of what they do)
*#9090# - Service Mode Diagnostic Control
*#197328640# -General Test Mode
*#0*# - Band Mode
*#7363# - Quick Test
*#9900 # - System Dump
*#0011# - Cell Information
*#8888# - SM FTA HW
*#0808# - USB Settings
*#638# - Tethering
*#2683662# - Advanced Services Menu
*#0228# - Battery
*#2663# Advanced Firmware Menu
*#0514# - Sysyem Dump Alt
*#1106# - Grip Sensor
*#15280*369# - Version Review
*#2228738# - Calculator Test
*#34971539# - Carmera Firmware Std
*#35789# - Device Keystriing
*#622# - Unsure what this function does
*#66336# - CP Ram Dump
*#7277# - reciever call mode (wifi/data)
*#77467# - IMS Settings
*#8736364# - Software update
*#87976633# - Unsure what this function does
*#2884936# - Crypt Auth
(big one hope you got your spc or msl available)
**05**(msl/mmi/spc code)# -unlock Sim (mmispc)
if you dont have your T-Mobile sim unlock code then it is easy to get. Simply call your T-Mobile hotline from another phone. Request that you get a sim unlock code because you have accidentally locked your phone. they will have you go through instructions to reset that number. the 6 digit code that they give you will be your msl/spc code that is necessary to unlock your device.
Please try these hidden menu dialer codes and tell me if you come up with anything that i may find interesting towards rooting and oem unlocking the phone. thanks

Found this on android.stackexchange.com don't no if it might help
I found one clue about CP/AP, and it's from a discussion at Android Central. One Galaxy S4 user with AT&T in the US had to use this service menu to switch from CP to AP, in order for Samsung Kies software on the PC to recognize his phone. It kept saying SGH-I337 does not support initialising. It seemed to have something to do with a custom bootloader by AT&T, and it was probably set to CP mode by default. That's a clue, but not a clear fact. Switching it to AP made it recognized in Kies. – samirg Aug 31 '15 at 15:47

Maybe switching it will have u some kind if advantage with the bootloader I'd try myself but my cpu is down and out the moment
Using the *#0808# code of course

This actually isn't working on Samsung Galaxy S3 Mini Verizon in 2018. It actually tries to dial an actual phone number, not go to the unlocker. What is wrong with the Verizon version of the Samsung Galaxy S3 Mini? Why doesn't this work on the Samsung Galaxy S3 Mini Verizon on Android KitKat 4.4.2?

The correct code for extended Version Info is *#12580*369#
It will work on most but not all models/firmwares.
Why is the VoLTE provisioning option not active when you access the sim card menu. Any assistance will be much appreciated. My carrier supports VoLTE. Current O.S Oreo 8.1.0 April Security update.
Yes same problem. Not sure if there is compatibility test whith the operator to have have this option in the menu.
Someone told me that webhave to wait for the next android update to activate tgis option. Not certain though.
I think to activate volte your carrier must first verify it and it will update. Then only you could use. My previous phone had the same issue until a new update pops up and mentioned volte for my carrier is now supported
hi, I bought a note 8 mobile(SM-N9500 model number), but I am not able to enable VOLTE option in that.
Someone, please help me to resolve this issue. except that everything works fine. i have searched many forums and threads, but i did not find any helpful thread which can resolve the issue. Please suggest any custom ROM or firmware to enable VOLTE.
Earlier there was an option to enable volte through shortcut master, but now that is not working and they have blocked that loophole. kindly help me how to root or any other rom for sm-n9500
please find below my phone details:
Model - SM-N9500
Device type - greatqltechn
product name - greatqltezn
product code - SM-N9500ZKGTGY
Firmware CSC Code - TGY
CSC Country Hongkong
Bootloader version - N9500ZHS4CRH1
PDA version - N9500ZHS4CRH1
CSC Version - N9500ZZH4CRH1
Baseband version - N9500ZCS3CRH1
Android version - 8.0.0
Hardware board - qcom/msm8998(64 bit)
platform/chip - MSM8998
GPU - Qualcomm Adreno 540
please ask me if you require anymore
Kindly help!!
I Bought my note 8 directly from my carrier, fully paid for it, so it was unlocked, there was no Volte option, some days later I received a message from my carrier telling me that my device was able to use the Volte service, and asked me to take my device to their service center, I did, took the proof of purchase with me, they checked all the pertinent stuff, and they activated the service in their system, they issued a new sim card, and that was it, the volte option appeared in settimgs, that was my experience, so, I think that in some cases the volte settin switch depends on the CSC part of the firmware, I mean, it is carrier-dependant
Has anyone managed to enable the Full-Port Switch on a Realme Device yet?
This is needed to configure the LTE Modem to enable a matching carrier profile that supports VoLTE.
I have the Qualcomm QPST PDC programm and know how to do it on a Oneplus device.
But I can't enable serial mode and the Full-Port Switch on my Realme X2 Pro.

Just do it without the serial port ON also can enable the volte and vowifi.

How?
Is there a "easy" way to do it?
I've read you must enable the diag/serial mode via editing the build.rop
how do you do it? ive been trying to figure it out.
Here is the tutorial I found.
The code to enable serial mode is in the 2nd code box.

diag mode for realme x2 pro
nvm its fixed
There is any way to do this without root? In stock rom?
