F350 Variants and Hidden Menu

I've been stalking this phone for sometime now. I live in the U.S. and know I need the F350 version. However, I'm confused as to which F350 I need. What is the difference between the S,L and K versions? Also, I know the phone has a hidden menu which allows you to change the LTE settings. However, has anyone been able to actually get the changes to stick and work? My G Pro 1 has the same menu and when I tried to change the LTE settings it wouldn't save them.

Msl code

I have a note 5 sm n920p. After i ugrade to mm. The mobile data toggle was disappered.and i cant access 4g lte data only on 3g data. I ve senn that you need a mls code to change the settings and have access to modify options. Does anybody how to activate my phone to use it? I live in europe i dont know how thing works for sprint

##data# from the dialer then click edit then LTE. Check lte enabled to see if its checked and change your lte bands if needed. Or instead of clicking on lte scroll down to more then click HDR/1x selection then set it from there

Endri, Was your phone's original firmware 5.1.1 and with the logos of Andoid-Al-Yemen...?
SM-920P does not have the necessary 4G Bands to use in Albania. I mean, the modem is capable but I DO NOT recommend trying to engineer the Qualcomm processor... By the way look for a sticker on the upper bezel of your phone if it has any "QUALCOMM 4G" adhesive sticker...
Anyway, don't mess with the settings on the data or service menu or you will sim lock your phone back to sprint. If you are brave enough and want to mess with the settings, my advice is: Do not touch anything that has "NV" written to it! Probably you will re-lock you phone back to Sprint as this model's NV golden backup locks it back.

Best T-Mobile APN settings?

I have a metro variant moto g stylus/pro. I know since metro and T-Mobile are on the same network you can switch between the 2 APNs. What is the best T-Mobile APN? Also on my old LG using code 237634#*# 8f im correct on the code unlocked a menu that allowed me to change different network settings and unlock locked APNs also a metro variant. Does anyone know if there is w similar code for moto phones?

In settings, you can go to mobile network, then advanced, then access point names. You can't change what is already there, but you can add one. Here are screen shots of the TMO default settings.

That's why i was asking about the code. Because on my lg stylo 4 (metro) i could use 277634#*# and unlock the preinstalled APN and modify it.

Can you flash ATT, VZW to XAA Branded in Download Mode

Forgive me if this has been covered but I havn't found the answer. I've flashed just about every phone I've ever had but my question here is can I / how do I flash to where the phone reads as XAA in download Mode?
The situation is my phone was originally on at&t. They unlocked it and I'm on Verizon. It all works great (it still says at&t on download Mode screen)
My problem is that if I log into the my Verizon app it disables my visual voicemail. I finally got a Verizon tech on the phone that explained that it is unsupported due to originally being on a different carrier and their system identifies that and disables the VVM. The only fix I can find is to put my sim in my backup S9+ that came from Samsung unlocked (or any Verizon phone) and I can then reactivate my VVM by resubscribing.
I currently have 3 Note 20 Ultras. One Each originally from Samsung, ATT and Verizon but the AT&T is the only one that is 512GB or I would just switch phones. I have flashed them all to U1 firmware but notice they all still reflect the original carrier in Download Mode so again my question is can I change this by flashing it / or is it just a matter of what sim card is in it when it's flashed? I need it to be seen as XAA by Verizon system so not to loose VVM... Pics attached.
Any advice here is greatly appreciated in advance.

Just a try... You can try the *#272*imei# method... But thats If it works. Not sure if the sims has to be in the phone for that to work.

Yes it brings up this menu... So I just select the XAA and that's it? I've been reading forums and this method is reversible it seems ... I'm familiar with Odin and all that but these hidden menus are new to me...
Thanks for the reply btw

You may have to activate the bottom most option to stay.
Don't worry if you can't access the menu after the change. You can download samsung band selection and change to automatic or one of the lte options then back to automatic to get to the menu.

CSC Guide
CSC (which I think means Carrier Service Code) helps to set what options for settings show in the device for things like voicemail and wifi calling, as well as sets network code information for things like carrier aggregation combos.
When you go to your phone settings->about phone->software information and look in the Service Provider SW ver. section, you will see as the last line a combo like XXX/YYY/ZZZ. This indicates what carrier sales and network code is set and what brand the phone was manufactured as.
I think of the XXX/YYY/ZZZ configuration as follows
XXX=Sales Code-What kind of features are setup in the firmware like wifi calling, video calling and settings menus
YYY=Network Code-What kind of network features are set for things like carrier aggregation and LTE/5G bands
ZZZ=Manufactured as Code- What model the phone was originally manufactured as. Ot has no affect on the system settings or options. THIS CAN NOT CHANGE. IT SHOULD ALWAYS BE THE SAME. ONLY A ROOTED PHONE WOULD BE ABLE TO ACCESS THE FILES NECESSARY TO CHANGE THIS.
for more details, refer to post:-

Hello All, Many people have asked about service mode and CSC related questions and I thought we should get a discussion going that is all in one place. *DISCLAIMER* I do not take any responsibility for any issues that may occur from changing...

Activate 5G network capability on the Velvet

Thanks to paolotheking and this thread about an important secret code for the Velvet and other devices:
LG Velvet Hidden Menu code
Enjoy: #*462633*#900# Works with G900EM
forum.xda-developers.com
I could finally activate the 5G network capability of my phone.
I have a Dutch (NLD) genuine SIM unlocked Velvet LM-G900EM with latest Android 11 v20d-EEA-XX installed.
If you hit with the phone dialpad this sequence:
#*462633*#900#
it will lead you to a hidden menu where you can find all sort of information and tweaking options.
You have to choose "Field Test", then "Modem settings". You will have here many things you can change. Go to "RAT Selection", it will give you many more options than the ones you find under the regular "Network settings".
I tested here first "LTE(5G NSA) Auto" and it instantly made the 5G icon appear in the task bar! So I then hit the "GSM/WCDMA/LTE(5G NSA) Auto" option. I now have up to 5G automatic network selection!
Only issue is that under the regular Network settings, "Preferred network" states now "26" and if I want to see what other options you have, it only lists the options up to 4G preferred and it will go back to 4G maximum. So you have to go through the hidden menu again to activate it.
I also tested that if you power off the phone, 5G maximum stays activated when you power on the phone again, good to know.
You may also try to tweak your 5G bands by selecting them in the corresponding menu "Band Selection" in the "Field Test", "Modem Settings". Some of them might not really work though, as it might be hardware related depending on your model.
Hopefully it can help people finally being able to use the 5G network of their provider with the Velvet, and possibly other LG 5G phones like the V50(S) V60, Wing. You just have to put your model number at the end of the secret code ...#900# for the Velvet, ...#510# for the V50S ...#100# for the Wing, aso, if I understood it good.
Edit: works for the LG Wing too, just tested it!
