I come across trying to fix my lte by selecting other bands by using the sammy service mode app to access settinga to change the lte bands but it says it's blocked by the system. So does anyone know how to get it to work correctly? Know what is blocking me from accessing the bands? I know*#27663368378# takes me to the main service menu but no bands under CDMA to choose. Then the *#0011# brings up a no service imei certi : na. So that way seems blocked to. So any help? ?
Any help???

Hey guys,
I recently noticed that the default network mode on the Google Edition 4.2 dump is set to 0, or "WCDMA Prefered". Thus not enabling LTE on our devices by default.
It can easily be changed by using *#*#INFO#*#* on dial pad.
Im wondering if anyone knows where the default network mode is set or how we can modify the default network mode.
Im assuming its somewhere in Phone.apk or Settings.apk or some bool god knows where, if anyone can shed some light would be appreciated.
didnt work for me is there a diff code to enable lte or have i got to reflash a diff rom
I always used *#2263# to modify network mode

You guys are off topic..
I would also like to know how to change preferred network mode on my GE rom. None of the suggestions above work for me. If I enter the code *#2263# it tries to start something, but then it FC.
*#*#4636#*#* set it in there.
Set your default network mode in your build.prop too.

What are you using to set in build.prop ? The CM10.1/2 methods of doing this does not work.

ro.telephony.default_network=(8 for me because I work with CDMA)
With that I also add a lot of prop lines for the Verizon network specifically. You'll have to add your own network's information
No matter what you set it at though, if you go into network settings it will auto-switch back to WCDMA. I haven't fixed the link and switching yet but I did change that menu link to automatically open up *#*#4636#*#* instead of the menu that switches it to WCDMA. Kind of a work around for the time being.

The point is to hard code whatever property that menu is changing right into the rom.

I agree, and I haven't been able to get it defaulted to my network by the any decompile/recompile system edits I've tried that i found through researching/reading. I'd welcome the direct answer as to where that specific bit of code lies but given this thread and the lack of answers I'm going to guess that help isn't coming.
I've been slowly working through each core app and framework editing everything relating to GSM, baseband, and radio. But I've not found or fixed that menu setting that defaults to wcdma. I've found the menu but nothing that would initiate it automatically changing to WCDMA without even clicking the dropdown menu.

Does anyone know how I could lock into LTE only mode? The phones I am using (T-Mobile & AT&T S5) is not rooted. Nor am I allowed to root it. I've search through all of the debug menus and its seems like I can only lock into certain bands. I havent had any success sending AT commands either....but I am not sure this would still even be capable as I do not know the Qualcomm AT commands to lock into a certain RAT.
Try this: Dial *#*#4636#*#*, look for LTE only option and select that. Hit home to clear out of dialer. Hope this works!

Ok, so I figured it out. If you dial *#2263# and select "LTE Band Preference" it will lock it into LTE only (I am using an unlocked T-Mobile phone, not sure if that makes a difference). I have confirmed this via AT Commands. I have a new question. I have queried what bands can be selected. Does anyone know which one would be for LTE Band 17? What is "41.WLAN_US_5000"...

If anyone is interested, and using xposed, I created an xposed module that allows you to have a widget on your homescreen which easily enables you to change the network mode of choice.

That link shows an LS990 ZV4 unlocked on an international carrier. Sprint has always been willing to unlock the SIM for use with an international carrier. Even with Google Translate, none of the posts on that site make any sense. Were you saying this somehow meant domestic GSM unlocking was now possible?

because the user indicates that they are cell phones with bad ESN.
this will unlock for domestic use? I have internationally unlocked, but would love to unlock domestic
Someone said change SPR to OPEN setup SIM and APN then change OPEN to spr reboot recovery wipe cache and this will make good for Domestic APN..I will try later on today and report back
Yeah it works...4G US GSM carriers
Im stoked to hear it works. 4g and spark hardly exists here. Can you report which carriers you connected to successfully with 4g? I heard only 3g was possible on tmobile (which has my interest for sim)

which parameter did u change in build.pro,I change the ro.build.target_operato and ro.carrier to open,the signal will show in satart quickly then instead of com.andorid.phone wrong all system ui wrong,u should toggle airplane mode then no wrong info. so I wander what u done could make it work fine with no wrong message? I need to wipe? or other operate?thx:laugh:
change ro.build.target_operator to spr instead of SPR.
changing it to OPEN will make the g3 crash over and over.

You need to fix the permissions to the build.prop to stop fc errors after editing the build.prop on the G3.
Everytime you edit the build.prop you need to fix its permissions before restarting your phone.

Thanks for the reply. How do it do that? I only changed the "spr" and changed the APN on the LTE and the MMS.
Hey!
I've had my Honor 5X for about a month and I haven't yet been able to connect to my carrier's LTE Network.
I know the bands match and my phone even shows my carrier's LTE network when I turn off automatic network selection, but I can't seem to connect to it. It defaults to 3G and the highest I've gotten is HSPA+. I've tried different carriers as well but it doesn't connect to ANY 4G network.
I have 4G enabled in the settings. There's no way to force LTE as Huawei has disabled the hidden network selection menu.
Any ideas?

There is a way to edit build.prop to force it to choose but I read it somewhere and now can not find it. May be someone can explain how to do it.
editing build.prop may help
search for this line in build.prop
ro.telephony.default_network=9
change it from 9 to 10
disclaimer: always do a backup before proceeding , and do not blame me if you did something wrong of if something wrong happens..
Reset APN.
I can't edit the build.prop file because I'm not rooted. Once I do root, I'll probably install CM13 so that won't be an issue.
What I wanted to know is why this is happening. It should connect to LTE whenever it's available without me having to force it.
Anyone else having this issue?

I recently purchased a refurbished phone Samsung Galaxy S21 5G. I just got it yesterday, and found that I am not able to use my mobile network. The sale said it is factory unlocked, and according to the descriptions, it should work just fine with my US Mobile SuperLTE network as well. When I switched on the phone, I see Verizon on the screen and so, I assume that it was locked to Verizon in the past.
When I tried to change the network settings, specifically the APN settings, I get the message "Access Point Name settings are not available for this user." The three dots on the top with reset to default is also greyed out along with Network mode in the previous page. When I click Network Operators and try to connect to the network manually, I am only able to connect to Verizon Wireless and no other. But, calling and messaging seems to work fine. Is it that the unlock process has not been completed properly? Did any of you face the same problem before? It would be great if there is something that I could do to unblock the APN settings as the rest of the phone works really well. The specific model is SM-G991U.
Thanks!

So, you need to go into the settings menu and find about phone, software info. What you want to find is the CSC information.
It will basically look something like this: XAA / XAA-XAA / XAA (or some other letters like VZW or ATT or TMB etc etc.
What taht will tell you is very helpful in determining what rom the phone is running and what kind of device it was originally. Find that in your device and post it and people will help you to figure out what it means.

So the csc info is complicated, I'm no expert on it. But it does look like the OYN indicates it's a multi csc rom. It does have XAA as a part of the code, and that indicates it's 'open' for that specific part. But all the others are VZW. So it's running a vzw rom, obviously.
Your sim US Mobile uses both verizon and t-mobile networks. So it working for calls and texts makes sense, as a vzw phone. You could use patched Odin and flash a different (open) rom, but first you should verify that the device really is unlocked from vzw.
Best way to do that would probably be to insert another carriers sim card and see if it can make calls / texts. If not, it's not unlocked. But are you saying everything works now except mobile data? IOW, no internet access?
I had an international sim card at hand and I put it in. Interestingly the APN settings are no longer blocked. But, I do get a notification from setup wizard saying the inserted sim is not from Verizon and some services may not be available. But, messaging still seemed to work and I was also receiving 4G.

Oh then yer okay. That message from verizon can be gotten rid of a couple of ways; 1) use adb commands to disable the specific packages 2) use patched Odin and flash a different rom
VZW is the only rom I think that does that, and it's very annoying. I don't remember exactly which packages have to be disabled, but search google and use xda and vzw in keywords and u should find it.
The 2nd option would be my choice. It would do away with vzw crap and with an open rom you may find volte and vowifi will work also.
cheers
Thank you so much for your reply. That sounds great! To just give it a try, I tried putting in a TMobile sim and phone restarted to install software for TMobile. After that the APN settings were unlocked and now I am also able to connect to the internet using my US Moblile sim. The only problem is the the network mode is greyed out.
This rom I think only recognizes network from major telecom providers. So, just flashing with an unlocked rom would just help to unlock all the features and also remove telecom specific crap. I will try to flash it today.
Thank you again!
I also just flashed the stock firmware which is fully unlocked. And there is no bloatware from telecom OEM's. I am now able to use the network and set the APN's, but the Network Mode is still greyed out. Is it possible to know why? I am guessing that if the phone is fully unlocked, I should be able to change the Network Mode. Is there any other info that I can give you to help understand what is happening? I do not see vowifi as well.
