D821 with USA band

Hi, i've got a strange thing , i bought an D821 in the netherlands and it's showing USB Band in the radioband section , shouldn't this be : EUROPEAN Band ?
I've got troubles with service dropping , that's why i asked
Thx for helping
:good:

I don't know what you mean USA band. How are you checking this?
All baseband software is interchangeable between the 2 models. It may just be the baseband you're using isn't good for you.

This gives the radioband you're using

Won't work on mine. Too custom

http://forum.xda-developers.com/showpost.php?p=54857245&postcount=84
no win so far. but hopefully will.
wife's phone was able to get into on the 3rd go.
my nexus now will not boot after flashing diag, working on it.

LTE only?

Has anybody been able to do LTE only? I I have weak LTE where I am but it still is faster than hspa here but it keeps defaulting to slower speeds.

Your phone decides when to switch over to 3G or lte. Depending on the connection.

I think he's referring on how to do it through the service menu. On the Nexus 5 it's *#*#4636#*#* not sure about Samsung phones.

*#2263# Choose LTE all bands. Been using it on my note 4.

Neither of these short codes do anything on the S6. Does anyone know a working one?

*#2263# works for me

I see. I'm running the H3G firmware. I'll happily flash a different operator firmware, any idea which one works?

Hi All,
My first post here, nice to meet you all. Sorry for digging this thread up.
Galaxy S6/S6Edge users, can you please let me know on what firmware (Baseband version), dialler code *#2263# works for you?
Cheers,

A lot of these codes are not working on the newest baseband, looks like Samsung restricted them. They are only working if you download the PhoneInfo app and launch the code with SuperUser (root).

If you root and flash XtreStoLite rom there is a LTE only mode.

Hi,
I'm on the latest Xtrestolite v2.3 and I do not have the LTE only options in the settings (i only have 2G only, 3G only, 2G/3G and LTE/3G/2G), does it work for you ?
The *#2263# isn't working either.
EDIT : I found out how to fix the bug : if you are using your mobile in Frech you have to switch to another language to make the LTE only option appear.

I'm on 2.3 and I have that option, in mobile networks

easy way to add is to write in your others.xml or feature.xml this >>>

Right, thanks davebugyi, you are right and I am aware of that. That is why I was wondering what Baseband version PunishedSnake and Djamog had in mind. I would like to know which commercial firmware exactly includes *#2263# features working, so I can downgrade/upgrade mine, on SM-G920F.

This works great, thank you for the answer.
Do you know any other network forcing related features and how to enable them? Menu *#2263# I am trying to access, similar to *#0011# (and Q0) in previous models, includes Band locking and probably more.
Thanks,

Edit LTE bands?

I have Samsung Galaxy S6 edge SM-G925P (Sprint verizon) it's already unlocked for GSM.
Now, I want to use LTE - but the model isn't support Band 3 and 7. Can I make them available? How?

You need to root or get your msl code from sprint. From there you have a few more possibilities.

I am rooted + have msl code. guide me please.

Enter ##data# on your keypad. Hit edit and enter msl. There are menus for LTE.

yes, but I can't see band 3 + band 7 in there.

Maybe the cdma version can't access those bands.

I heared there is a way to hack the lte band settings and enable all bands, but how?

Read this thread. Might have to upgrade to a different baseband http://forum.xda-developers.com/verizon-galaxy-s6/help/sm-g920v-capable-lte-band-3-5-7-t3115021

VoLTE/Wifi & 5G on OnePlus Nord

Has anyone been successful in getting these instructions:- https://forum.xda-developers.com/oneplus-8-pro/help/volte-vowifi-australia-t4095097 working on a OnePlus Nord?
I have the 8 Pro and have VoLTE/Wifi and 5G working perfectly on Telstra, but I cannot get it to work on the Nord following the same instructions.
It keeps erroring saying "Exception has been thrown by the target of an invocation."
I was hoping it was just a driver issue, but nothing I have done has been able to fix the issue and was hoping someone here had luck with it.

in the secret menu *#800# i dont even see the switch option.
I'm also on telstra but am yet to have a look if i can get 5G

We don't have 5G, but I successfully enabled VoLTE with that guide.
Sent from my Nord using XDA Labs

Which drivers did you use? I cannot get it to connect on multiple computers for some reason.

I only installed the apk and enabled VoLTE in the *#800# menu.

Just using logkit did not seem to properly work for me. Even though VoLTE option appeared in SIM settings, the VoLTE icon did not appear on status bar. I had to follow the steps in this YT video to get the VoLTE icon to show up. Only different thing I did was use a newer version of QPST

When check Serial on engineering mode apk close. The successive step don't work

If there's no error messages, then maybe try activating other carriers. Are Telefonica_UK_Commercial & Commercial-VDF available? In an older thread, a TIM Italy user used one of these.

I have new Nord. I just change logkit version and turn on volte and wowifi switches. Voila!!! All is working (From Vodafone/Türkiye)

I don't have 5g option. I don't understand.

I wrote to the my carrier /Orange - Slovakia/ and they say that more carriers will have enabled VoLTE and VoWiFi on OnePlus Nord in the next update 10.5.7
But you cann try code: VoLTE *#*#86583#*#*
VoWiFi *#*#869434#*#*

Can someone confirm if VoLte is working on telstra network on OnePlus Nord.

Yup, sure does!
Even 5G too
Refer to this post https://forum.xda-developers.com/t/volte-and-vowifi-in-australia.4095097/post-84111603

Has anyone managed to get VoLTE working on 3UK or Smarty Mobile UK? Got only VoWiFI option under SIM settings.

I updated OTA to 10.5.10 yesterday (and re-rooted with Magisk), but the update removed the 5G fix I did to get Telstra 5G working. What else is that I can install the EngineeringMode apk, but I can't open it with *#800# or *#801#. Is anyone having the same problem?

check if Google Dialer is the default phone app. If not, use an activity launcher and open EngineeringMode.EngineeringMode or change the default phone app

[HELP] Converting OP 7 Pro 5G Sprint to International Variant

I've a OP 7 Pro Sprint Variant, Model: GM1925. When I was in stock ROM, the latest build was 10.0.7.GM25CC. Few weeks earlier, I followed the guide here and was able to successfully convert it to EU firmware. The reason behind this conversion is to get the latest OOS updates asap. But it seems the updates for 5G phones are lagging far behind. My phone is running on 10.0.11.GM27BA currently.
Further, I tried to convert my phone to International variant by following the guide here but failed. More specifically, it stopped after 'Param preload'.
Now, I badly want to convert it to International variant. I don't mind if losing 5G would enable dual sim functionality on my phone.
Is there any way?

Late on the replies but converting to international is impossible due to different partitions. Dual sim WILL NEVER WORK because we don't have the config files for dsds on the X50 modem. Because of the 5G, updates are behind and will be for basically the phone's EOL. Custom roms are a grey area as modem needs porting and rotation needs fixing, and Android 11 custom roms won't work (due to no modem functionality)
