Is it possible to add a GSM or WCDMA options into a rom? I ported the VZW HTC Thunderbolt rom to HD2 (yah i'm crazy) but if I go into *#*#INFO#*#* , there are only LTE, CDMA, etc options and I don't get any signal. Replacing the Phone or Phoneprovider from another rom doesn't help.
Could a possible solution be to manually disassemble the phoneprovider apk and then add the extra options into it?
anyone?
.
Philip Mangelow's "Network" app allows you to switch to GSM (it really just lets you access a device menu). I don't know whether that would be enough, especially because the changes don't seem to persist over a system restart.
I have already tried that app, and it does give me any extra options, unfortunately..
Hello Xda, i have been a dormant user of ROMs on my galaxy s2.
I liked the cyanogen stable mod 7 because of a unique setting where i could toggle the 2g network.
Believe me the place where i live, the 3g bandwidth is crappy and for my use i prefer the 2g network.
My question is , are there any other ROMs which allow such an option of toggling between 2g network.To be more precise i have attached a screenshot below.
Any help regarding this is appreciated. I am not looking for an app or tasker script that allows me to toggle 2g network. I am looking for a ROM other than the cyanogen mod 7.
Thank YOu
this option is available on all roms. it can be found under mobile networks settings on samsung roms. Network mode > GSM only
Hi , is there anyway to force 3g/4g only on this phone..? I've seemed to try every hidden menu code and nothing seems to work.
The reason I ask this is that I've downloaded a global firmware (171) for this phone and unfortunately my carrier no longer does 2G and when im getting poor 3g coverage it switches to 2g and lose service completely. This never happened on my old carrier firmware as it was setup not to switch to 2g.
I also think it's because I have a single SIM version and this new global firmware is setup for dual Sim.
Anyone got any solutions? Sounds like downgrading firmware isn't a option at the moment...
4G only on Huawei Mate 20 Pro works!

Hello,
yes, now we finally found a solution.
Do exactly as described:
1. Download Settings Database Editor from playstore and open it
2. Look for hw_networkmode_preference and edit the stock value "9,6,2,1" to "11"
3. Restart the device
4. Open Settings Database Editor
5. Click on + Add new setting at the top
6. Type "hw_add_4g_only" (without " ") and press save changes
7. Type in your country code, example "502" Malaysia or "262" Germany. Press save changes
8. Type "hw_add_4g_only" (without " ") and press save changes (YES, REPEAT STEP 6)
9. Type in your country code, example "502" Malaysia or "262" for Germany and press save changes (YES, REPEAT STEP 7)
10. Restart the device and VOILA!
Now you have access to ALL network modes. Select "LTE" or "4G" for 4G only functionality.
Like this, you have stable Internet nearly where ever you go, without dropping back to overcrowded 2G/3G Networks.
Best,
Stefan
i know this thread a month old but i tried this and 4g only option is there but it also removes all other options which for obv reasons is not good if in a non 4g area, is there a way to add the 4g/3g option .
ps: i found an old thread to add the 3g again but have to manually switch between the 2 options
Hey,
My device updated to the new firmware yesterday and I have lost the '3G Only' option. Is there a way to unlock this?
Apologies if this has been asked before but I can only seem to find the 4G solution. Thanks in advance

I can't send any text messages over any network mode, and to make or recieve calls I had to change modes.
The phone is relatively new and since it's not mainstream most carriers don't support it yet. Some people say they have VoLTE enabled and it works but I personally switched to Singapore EX and it seems VoLTE isn't detected at all so I started digging and it seems this issue is present in most Chinese phones. (https://forum.xda-developers.com/t/guide-activate-volte-and-vowifi-simple-and-clear.4116051/) In this thread they used the Qualcomm tool and exploit the bug in EngineerMode on OnePlus phones which we don't have an access to and since we can't root or unlock the bootloader we can't modify build.prop or change any system files.
-----Maybe it's my carrier, maybe it's the Singapore ROM so please if VoLTE and VoWifi works for you could you post here which country you're on, which ROM version and if you changed region before or not.------
First a warning: If you aren't tech-savvy, experiencing issues or want to potentially turn your phone in a paper weight do NOT try this at the moment. We do not have the tool to restore your phone back (wiping data might work but idk). You can send your phone to Oppo for repair but you might have to wait for a month or two.
I don't know if you need to unlock your phone from the other thread to have access to this mode(I did have it all decrypted during this test) but in addition to the *#808# engineer mode and *#*#4636#*#*(Where you can check if you have VoLTE enabled) I found we have access to *#36446337#.
In *#36446337# I managed to enter "Protocol test switch" -> "MBN TEST" and switch my profile from Common-Commercial(I think it was this one) to Commercial-DT-VOLTE. The phone rebooted and everything is fine but "MBN Validate" is giving me an error when I run it and I can't test if it works because I'm currently out of the country and my temporary SIM provider doesn't support VoLTE.
It's probably nothing and the error is because of the lack of developer files on the ROM but I need people who can test if these profiles act like the flashing from the Qualcomm tool in the thread mentioned above.
So once again if you don't have VoLTE enabled and are feeling a bit courageous - give it a try.
I think the problem maybe for those that changed to Pakistan build on Android 10 and then switched to Singapore ex to get ColorOS 11 and dual SIM meant that things like VoLTE do not work on those builds.
I did it a different way as wasn't bothered about dual SIM. I was on A.46 UK , waited for EU to get ColorOS11 , then switched to EUEX on sec5 and downloaded ColorOS11 c.57 through Belgium VPN.
VoLTE is working for me. it's not present in SIM settings( WiFi calling is) however when I look at my call log there is a VoLTE HD icon next to all my calls, so is working.
Since being on ColorOS11, I have tried several different regions on SEC tool, EUEX dual SIM, Singapore EX, back to GB CPW to check still works and now back to EUEX. Build number always changes to different region in about phone when I have made any changes and check however VoLTE has always remained working for me and is showing as provisioned in engineer mode.
I am from Germany and have a phone with Vodafone FW originally. I switched region to Singapore EX, than installed the Pakistan FW and got C.5 and C.6 via OTA. I switched the region to EUEX (DUAL SIM) and didn't receive the update to C.57, so I switched back to Singapore EX and got the update to C.57 when using VPN Hongkong, which was quite funny.
VoLTE and Wi-Fi calling is working fine with Vodafone, but you can't toggle it in the hidden service menu, it's just active! You can activate or deactivate Wi-Fi calling in the regular settings, but VoLTE is just there, you can't deactivate it.
Both Wi-Fi calling and VoLTE are shown in the bar on the top. With the former Vodafone FW, VoLTE was not shown with an icon, but it was nevertheless working.
Hy here T-Mobile shown volte and Vodafone don't shows but on the status bar there is the volte symbol

I am in the same boat as you. I rebranded to Singapore to get ColorOS 11 update, to use 2 SIM and Call Recording, along with Theme Store, etc.
While on my previous phone (Xiaomi Mi9) I had VoLTE and VoWiFi and my carrier supports them and my SIM has that activated by my carrier, on Oppo Find X2 Pro it seems for them to work is needed special Modem Profile for the concrete carrier you use.
My Carrier is not listed at MBN Test Menu, I tried all the profiles available there, all Commercial ones and all Volte Branded ones and they are not giving me VoLTE and VoWiFi options available in Menu or VoLTE or VoWiFi functionality.
This method used to work on Xioami and Commercial EU Carriers profiles gave me the VoLTE and VoWiFi functionality with just Activity Shortcut access to this menu on Mi9 and simple dialer code to activate VoLTE and VoWiFi switch in Settings.
Oppo Find X2 Pro is not sold officially in my country and by all carriers here and that is why there is no Carrier Volte Profile for carriers from my country and thus it is not possible to activate VoLTE and VoWiFi with other Carrier Profile from MBN Test Menu.
Maybe if we find a way with a Dialer Code or some menu to activate the VoLTE and VoWiFi switch in Settings first this profiles from MBN Test menu will work...
I am out of ideas for now.

I'm pretty sure they force disable most of this stuff with region profiles (/etc/oppoRegion* folders)
At this point I honestly care more about GDPR protection,VoLTE and removing tencent/heytap crap than call recording and theme store which I don't use anyway.
So my plan atm is to wait for Oppo to release android 11 .57 .ozips so that I can flash back to european firmware then I'll see if changing region to EUEX Dual-SIM works and it's limitations.
This method might help people on EU roms with VoLTE, and I'll test it myself in the future, but at least for now *#36446337# lets us adjust MTU, 4G bands and some other smaller network optimizations.
Okay I don't know where to post this but I found *#649010# and this is where it gets into the spooky territory. I never tried toggling any of the options but I think "Full-port switch" option lets us connect our phone to the qualcomm diagnose tool just like the OnePlus phones from the Carrier profiles thread. I'm just documenting this code here so we know we have an alternative to the OnePlus LogKit.apk option in our Oppo phones.

Interesting to find out what these options do.
For some reason, non of these codes work for me now after doing the region change a couple of times.

We keep telling people - you gotta unlock every time you change region and even then the unlock lasts a fixed amount of time ex. 24 hours before it locks itself again

Unfortunately, the tool no longer works for me to unlock, the codes don't work. I'm stuck.

Works for me no issue. Try adding cloudflare dns to your setup, tether your phones connection to your pc while disabling your main connection and adding the number values from the original thread, fiddle with the loopback driver, disable firewall in windows or your router. Everyones connection and setup is different you just gotta find a way to make it work on yours.
Tl;dr it works you just got to tinker with it

Did you have the call recording option right after you switched region? I changed to Singapore Ex right after I got the phone, didn't see that option. Then I upgraded to ColorOS11, still did not find that option.

You have to give permissions to 'Recording' app, then open enable it in 'Call Settings'

Do you mean recorder App?
Already given all permission but still no call recording option, and the recorder only has cloud sync on its setting

Hello,
I own a realme gt2 pro 12/256 phone global version.
In my country(Turkey) I dont have an option for disabling volte.
As I checked a lot of sites, its told that there is a secret code for service menu and I can disable it from there.
But all the codes I tried arent working.
Do you know a way to make the volte option to appear or from where I can disable it?
I have tried resetting the network settings or apns

Sorry M8 but couldnt find it
I don't know if I understood correctly.Turn off 4G call?
I want to turn off volte
Turn off 4G call.
Dont have that option there
Settings - Mobile network - Select SIM 1 or 2 - there you will find an option 4G Calling
There is nothing like that also no volte checkbox
What does the option of the selected SIM card look like for you?
Why do you think you have VoLTE when you don't have that option.
I, on the other hand, lack the option of a Wifi call, but that probably depends on the operator's services
Because when ı make calls the volte icon appears next to time counter of the clock
Regarding VoLTE, I only have the option to use it with two SIM cards in the settings, but I only use one.
Try placing SIM in 2nd Slot and then check in settings
