Adding LTE band B38 (TDD 2600) - G3 Q&A, Help & Troubleshooting

Hey XDA,
I've been following this tutorial for how to add some bands but my phone simply doesn't see any networks when scanning for LTE on band 38.
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
I'm running CloudyG3 2.5 with ChupaChups kernel.
Has anyone ever changed their LTE bands on a G3 (and succeded)?
Thanks!

U have 4g simcard? I think your operator is digimobil, and u don t have yet 4g simcard.

I could not find the LTE on my phone with this SIM but when I inserted it in a OnePlus One I could browse in 4G. The SIM isn't the issue.

Nobody from all this smart guys that are here could not tell us how to make LG G3 to open band 38 on the LTE so we can get 4G internet on Digi Mobil ???? Right now since the android 6.0 update cant even access the hidden menu using that code.
Also another matter , since the root of Android 6.0 the micro SD card can not be recognized anymore.....don't matter what rooting you try the micro SD wont work no more. Nobody bother to fix this yet. Every one acts smart and writes here but all he does beat around the bush.
Awaiting for real answers.

Hi, I know that it has passed a long time since you've posted but here goes :
After trying to add band 38 to LG G3, i tried to update to Android 6.0, but couldn't because my phone was rooted. So i've flashed my phone to Stock ROM. If i remember correctly, my phone came with 5.0.1. Stock ROM is 4.4.2. After many, many updates i installed Marshmallow. Try to make all possible updates using the phone's software center, after that check with LGPCSuite if there are any other updates (they call it upgrades) and do them. Just like you i can't access the hidden menu anymore, and my micro SD card is recognized. Apparently after upgrading to Android 6.0 fixed it. (It shows 4G instead of H+ or 3G, now i only need to test the speed)

[Q] Why Does my Korean N7100 think I'm roaming and not connect to mobile internet?

I bought my n7100 on taobao here in China, and it's a Korean version. I put my China Mobile sim card in, and it makes and receives calls, and text messages and can use wifi with no problem.
The only thing is the mobile data doesn't work. I rooted and tried tweakker, and HiNet, to reset my APN and MMS settings, but that didn't work. My phone still thinks I'm roaming.. it displays
this message "Data Roaming, You have lost data connectivity because you let your home network with data roaming turned off".
I've also tried updating the APN and MMS settings manualy with information i've found on the web.
I've googled and searched this forum and I can't find much. I thought it would be an easy APN settings fix but it seems not to be...
I took my phone in to the local China Mobile store they couldn't fix it. I took it to a local android expert here and they didn't know what to do.
Any ideas would be greatly appreciated.
If you bought a Korean Note 2, you don't (shouldn't) have an N7100. I also purchased one through Taobao.
You should have an SHV-E250S, E250L, or E250K. Which one do you have? Check the baseband version under Settings > About device page.
No matter what, you're going to be limited to 2G only with China Mobile.
You're right, It's SHV-E250S, and I'm fine using the 2g in China on China mobile, but I'd just like to know how..any help?
Baseband Version is E-250SKSVLJK
Try removing all modifications to your APN settings.
Next, go into Settings > More settings > Mobile networks > Network mode and change it to GSM only. Also make sure that Data roaming is not selected. Run a new scan for network operators while you're in there to refresh your APN settings to the right ones.
In data network mode I only have 2 options "3g only" or "LTE Preferred" I have it on 3g only. I have now unchecked data roaming, but I don't see any place to scan for network operators. I have included a few screenshots here, sorry i don't know how to insert them.. http://tinypic.com/r/2198djn/6 http://tinypic.com/r/24dhfmx/6 http://tinypic.com/r/2zof98w/6
Now it's obvious why you don't have data. Is this the stock Korean ROM? Are you rooted?
I can point you to a decent ROM that will fix all of this, provided you have the patience to fix it. It's relatively easy.
Yes it seems to be the stock Korean ROM. I am rooted using http://forum.xda-developers.com/showpost.php?p=31801060&postcount=2 I'm more than willing to flash another rom. I've put about 20 hours into this so far, I imagine I can muster enough patience to finish it
Once they give us a damn Korean Note II section, this kind of information will be a lot easier to find.
Try this ROM for now, it's the one I've been using for a few weeks and I love it.

Thanks a lot the rom (715mb) is downloading now, I have tried to flash ROM's on my old galaxy nexus, and on this note II, but I never succeeded, can you please link me to a good guide, on how to flash this rom? thanks.
Odin is included in the download. If you're using Windows 7 you may or may not have the drivers for the phone, and can grab them out of the All-in-one Toolkit. Just installing the toolkit should install the drivers necessary.

The ROM you're downloading has two files and two pictures, as well. Open the pictures and follow along. All you have to do is click two buttons, select two files, then hit start. It WILL wipe your phone.
I installed that rom you suggested, I went into settings and did GSM only, and had it automatically find my network (china mobile) selected it, rebooted, and still it says i'm roaming so there is no connectivity... any more ideas?
Can you try somebody else's SIM?
There's no reason you should not be getting service unless something is not right with your SIM or phone.
I installed the rom you suggested, i went into settings and made it GSM only, also had it automatically correctly locate my network (china mobile) and it said "registered on network".. but it still isn't working, same problem, it says no connectivity cus i'm roaming.. any ideas now?
my gf will be home from work in a couple hours, I can try her sim card then.. my sim card was cut by me for my old iPhone.. is it possible or likely that the phone can still make and receive calls, but that somehow data connectivity was affected by me cutting the card? also one guy at the phone fixing store tried his sim card (from another company) and internet worked fine he said..

China mobile have various sim plans, from local to province to national. Are you using the sim in the same city in which you bought it? If not and you don't have a national plan, it could be why the phone is showing roaming. In China going from one province to another is already considered roaming unless you have a national plan. This is from my experience back 2 years ago. Also, you best check at a China mobile shop if you have data activated, gprs/edge is not activated by default, you need to ask them to do it.
I would advise you to switch to China unicom as they have 3g/hspa which is much faster than china mobile.

For clarfication, I am in Hainan, and the card is from hainan. I use the same sim card in my galaxy nexus without any problem. I tried my gf's card just now, it didn't say any problem with connectivity, and did not display roaming.. And it shows the G symbol (for 2 or 3 G I assume), and has up and down arrows next to it.. but it doesn't actually work for browsing the web or using apps over the data network.. I even reset all the APN settings and let it automatically find the China Mobile network, but it didn't help.. what if I try to set the APN settings manualy? and any other ideas??
Showing the G symbol is GPRS, which is 2G. You will not get 3G on the N7100, N7105, or Korean model Note 2 on China Mobile.
Sounds like you need a new SIM card. You can try to set the APN manually to make the data work with hers. I've never had to set an APN manually and I've used many phones here with all 3 carriers, so it's a bit odd to me. No clue why your card doesn't work, but since hers is working fine, it's definitely not your phone.
For the record, her card displayed G, but even after messing with settings, I couldn't get it to have working data network..
Today I bought a new card, and had it officially cut to size, put it in the note II and it's still telling me no data connectivity due to i'm roaming.. i'm so frustrated
edit: after restarting a few times and trying to automatically make it register on china mobile .. it worked on the 4th attempt.. it still displays data roaming, and I had to enable data roaming... but now it works, even though it says i'm roaming?? wtf
Ive the same problem with my Korean galaxy note 2 all voice service work perfect but when I tried to turn on data it says insert Usim Card to access network please help

LG G4 not showing LTE or 4g icon

I've got this issue where the icon of 4g and LTE not showing on my H818P (G4 dual sim) only got H, H+, 3G and E
I've doubled check the LTE bands and it's compatible here in Saudi Arabia
I tried to enter the code *#*#4636#*#* and open the phone information menu but I get "This Application does not work on this device"
I tried some apps from the market but with no luck .
does anyone got an idea or a fix for that, I really like the phone and I hate to return it since it's crucial feature to me
i got the same problem, im here in abu dhabi and i cant see the 4g icon or h+
I also do not get 4g LTE even though my model is supposed to support the band's of LTE my network uses. It's a shame but them again he speeds I get on HSPA+ are really not that bad. I think I will learn to live with it. Hopefully someone can come up with a way to enable more bands or unlock something that is blocking 4g. When I do connect to 4g LTE I can't send text messages so that's a no go.

The code is 277634#*#
Make sure you got the obvious set - network mode set to edge/wcdma/lte
Make sure provider data plan allows 4g, some plans/packages are restricted to 3g.

Well, I've tried everything.
At the end I've changed my sim card to a new one. It didn't work in the beginning but in a day or so it got LTE.
Hope it helps
Hi All,
I updated my LG G4 yesterday and i have a similar issue. the difference is i cannot connect to the 4G network. After i enable mobile data, nothing happens and i dont see the 4G sign. How did you get past this, did you factory reset or is there another way?
I tried to enter the code *#*#4636#*#* and open the phone information menu but I get "This Application does not work on this device"
Ideas?

edit : ok, I just figured this out, only software version v 10g OPT2 -H and v20e OPT2 -HQ have 3g+ and h+

Mine did the same. Go to "settings", then "networks", then "more", then scroll down to "mobile networks", then "system select". I switched from 'Global" to "LTE/CDMA" My lg g4 now says 4g lte
Pls help me fix my LG G3 issue. I can send messages and calls but cannot connect to the internet. No H+ or 4G sign on the network icon even I'm on internet settings. The issue even I changed my sim card.

Moto g5 no 3g and no 2g- no calls. Only 4g HELP!

hello, friends. Specially those who are worried about the so many problems with signal moto g5 users face. Im here asking for help. i have a moto g5 (cedric) i was working almost fine with oreo stock. i say almost because some times when i lost signal it didnt recover like any other phone woud, i had to reboot. now from almost a week ago i had lost signal and now i only have 4g. no 3G and no 2G, so no voice calls going out nor incoming ones. i ve done hard resets, flashing stock 7.0 and going back to stock 8.1 and nothing. on saw 3g for a little moment coming back to oreo. i also flashed carbon rom wich is android 9.0 to see if a custom rom helped but it didnt. i only have internet now and sms. and this is very frustrating. ive checked persist folder and everything is correct there. i have my imei right, this phone is like new but not being able to call is like not having a phone at all. also why i have to reboot to recover missing signal? is just a pain. this moto phones are really problematic when it comes to Signal management.
things to consider too: im currently on stock oreo, just rooted to be able to check if persist folder was correct and to backup efs folder. also my operator uses 900mhz band as 2g and 3g wich is an european frecuency not common in latin america. maybe that has something to do with problems im facing. the rom has cedric_latam_cust as the baseband. can anyone help me find one frome europe? im wondering if flashing one from there could help. the weird thing is that it was working before with that baseband.
so many people losing 4g, i could be glad if that was my case and had 2g and 3g only with full internet and calling capabilities.
im sorry i know it is a little bit too much information. but i really need the help

You could get your country firmware from here.
https://mirrors.lolinet.com/firmware/moto/cedric/official/
And don't flash older version firmwares as it will brick your device.and you should try a different sim card in your device to know if there is a problem in sim card or the device.

Thank you friend. I was able to download and flash an euro rom. Just to find that the baseband was not changed after flashing it. I even tried erasing modem and reloading non_hlos but I still have latam baseband on settings.

Not at all. I'm still having 4g only. As I mentioned before, in status it is still showing the same baseband that was in first place. One from Latin America. But I was trying to get it changed to an Europe one by fishing a new rom from O2. But it didn't change.

In my country we have 3 mobile operators. Movistar won't work (don't know why), the other works perfect on my phone. Mine from a week ago only work 4g. This afternoon it worked 3g but when I rebooted it stopped. Only 4g again. So no calls.
The first screenshot is with 3g and no signal
The other 2 is when rebooted having activated 4g

It seems the problem is API as you are getting 4g but no calls then it could probably API only, try editing the API or creating a new one. You can get the API configuration from the internet or the device which you get calls.

Did you try a different sim card in the device, does it working??? And does your service provider support LTE over call??? If it doesn't then change the preferred network type to LTE/CDMA/UMTS auto(prl). And switch your sim card to sim slot 2.

LG G710ULM UNSUPPORTED VoLTE ?!? (Straight-Talk US - T-Mobile network)

*********UPDATE********** I bought a new sim from straight talk and VOLTE works now! (GSM compatible Straight Talk Sim card) My old sim was from 2014, so it wasn't VOLTE compatible.
I have an ebay zombie LG G710ULM flashed to latest Google Fi Android 9 software, I received an email from Straight Talk (Wal-Mart US cell phone service reseller) telling me that my LG G7 does not support VoLTE and my phone will be unable to receive calls in January 2021.
-Using a network info app, the app is telling me it is connected to T-Mobile towers (so I have a Straight Talk T-Mobile compatible SIM)
-I can't find any options to enable VoLTE in settings, and wifi calling is erroring out
I was wondering if there are ways to get VoLTE and Wifi Calling working (Straight Talk supports it, but not my current ROM/SIM).
I can switch to the following sims supported by Straight Talk.
-AT&T Compatible Sim
-Verizon Compatible Sim? If my phone supports CDMA bands
OTHERWISE MOST OF US WILL HAVE A PAPERWEIGHT IN 2021!!!!!!!!!
Same problem
I'm having the same problem. Any progress on this?
I'd like to know this too. Surprised there is no traffic here with all the knowledgeable people on this forum.
G710EAW here. BTW There was an Android 10 update just two hours ago from Android 9. Someone with an 'EM' phone in another thread said VOWifi is "working now" but how do others know if it's working when January 1st comes around?

If you guys have cross flashed roms, then volte will not work. It doesnt work for any of us who have crossflashed. Whichever model.
You need to be on original software. Looks like some licensing thing that volte requires. They need to provision volte for all the phones. Sounds like they are not interested to provision it for g7. Odd that even EAW model which has original firmware, they sent that mail too....
Sad/Odd to see your carriers are suddenly changing to only Volte.
Is there a way to put it back to original software? I actually don't need it crossflashed to anything because it's a Verizon originally and I would like to use it on that network. Or does it not work that way?

Main issue is that your carriers dont want to provision volte for your G7s. So no guarantee if cross flashing back to original will work.
There is crossflashing guide in guides section with which you can go back to stock firmware. Do this at your own risk.
In our country we have a volte carrier called Jio. They provide an app called jiocall. Using that app you could use their service even if your phone is not volte capable. You will have to see if there are such apps for your carrier. Thats the only non technical, simpler solution.
I have some information that might make all of you guys happy.
I was told by Safelink Wireless that VOTLE is a function of BOTH the phone *AND* the sim card.
Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.
What's the correct service menu number for our phones?

Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.

Problem 4G+ Galaxy note 10+ (SM-N975F)

Hello everyone, first of all I would like to apologize because I am French and I don't speak English very well, but I think you are my last hope for the trouble I am currently experiencing.
I own a Samsung Galaxy Note 10+ (SM-N975F) with a Rom Surcouche Operator Bouygues Telecom :
- N975FXXU4CTE9/N975FBOG4CTE9/N975FXXU4CTE9
I wanted to remove my Bouygues Telecom Rom Operator to install a Samsung Rom Stock without any overlayer operator. The operation is well finished so I am now on the Samsung Rom Stock:
- N975FXXS6DTI5/N975FOXM6DDTH7/N975FXXS6DTI5
Except that since this change of Rom I have almost no more 4G+ where I live knowing that before I was always in 4G+ So I would like to know why just by having changed the Rom I lost my 4G+. ( Worries which lasts since September 21st, 2020 ) I wanted to go back but I passed from a bootloader 4 to a bootloader 6
Knowing that I'm with the Free operator, I tested my Free SIM card in my wife's Samsung, I'm getting 4G+ so the problem is not my SIM card, I also sent my phone to Samsung, the phone has no hardware anomaly so it's from the change of Rom, I tried to reinstall the same problem, I also made the wipe I tried everything ...
I also have at home a 4G+ router with a 4G+ plan with the operator Free and I am in 4G+ at full speed ...
I hope to get some help from you because on the French forums I don't have a single answer ... Thanks in advance for your help and sorry again for my english
Test the internet speed on both phones using your sim's data plan with speedtest. If the speed is the same in both then the problem of the 4G indicator is only aesthetic.
Hello bigcalvin, unfortunately I have tested but the speed is not the same at all in 4G+ I go up to 235Mb/s while in H+ I go up to 3Mb/s so there is no problem with the 4G indicator

Have you tried in different areas? What it seems like, is that the stock Samsung ROM is not compatible with your carrier. With system on a chip (SoC), carriers can turn off bands that they don't need, or as a means of locking you into their network.

Honestly I'm not going to lie to you I've tried everything I've tried a Bouygues télécom rom (bog) a SFR rom (sfr) a France télécom rom (ftm) and a Samsung stock France rom (xef) with my old Bouygues télécom rom (bog) bootloader 4 I always get the 4G+ since I changed my rom and I switched to bootloader 6 I never get the 4G/4G+ again and I sometimes get the 4G+ logos but there are 10 seconds left and then switch to the H+. ..
Hello, sorry for the double post but I don't know where to find help you wouldn't have a solution to my problem? Thanks in advance
I don't understand anything anymore on this phone knowing that my wife and at free and I can receive the 4g very well. I have a 4g router, I can receive the 4g free and my phone since the update doesn't receive anything anymore, I have to go out of my house and walk a good 100 meters to hope to receive the 4g whereas I didn't have this problem before I made the really strange update...
No one would have a solution to give me or manipulation to do I take all the information.
Try a "reset network settings" if you haven't already.
Clear the system cache on the boot menu; it never hurts to do so.
Hi, thank you for your answer unfortunately I have already reset the network settings I have also done the factory settings system cache also reinstallation of a new rom I had to do it about twenty times but still nothing :/

Yeah pretty basic stuff... that's all I got
Most likely a settings issue but you probably know more than myself at this point to troubleshoot this problem.
Try doing Google searches and view the results for other Samsung phone models and years.
Most times I can find a solution like this or trip over it as an indirect result while searching.
Some of the Samsung software issues have been around for years...
I've already searched everything on google I'm French I've searched on English forums and everything but I can't find anything at all.
I am in France with the mobile operator "Free" which uses the frequencies 700mhz/1800mhz/2600mhz I would like to know if there is a possibility on this phone to choose the frequency that I want one by one I have the impression that it is my 700mhz frequency that has a problem on my phone :/
By using the free App 'Shortcut Master (Lite) from Google Play, you can get access to the Network Settings. In there you can make Band Selection, allowing you to test network connections and performance per band (=frequency) or combinations of bands.
See following thread: https://forum.xda-developers.com/ga...guide-hidden-network-settings-exynos-t3995501
Hope this helps!
Hello OnnoJ, unfortunately I have already tested with this application so it doesn't work. However I compared everything with my wife's phone a Samsung so I have exactly the same settings as on her phone ...
I have to go out of my house and walk a good 200 meters to hope to get 4G, however I specify that before I made this famous update I was always in 4G at home inside and outside of the house and this is not a concern of the mobile operator because otherwise my wife would have exactly the same problem as I have now and I would also have exactly the same problem on my 4G router ...
I think I've done everything and above all I've tested everything and unfortunately I had Samsung on the phone and they put the blame on the operator whereas as explained above my 4G router and my wife's phone have exactly the same mobile operator so they would have the same problem as me ... ...
I would try to revert to the newest firmware that your carrier uses, just to see if the issue is about the bands, search for the latest firm for your carrier, provided that it is of an equal or higher bootloader version to the one you currently have installed, that is what I would do
@thominekevin76000.
Not saying it may help you, but the application works fine for me to access network settings. I use it all the time, as it helps me at home and at work to make the optimum band selection for that specific location to prevent hopping between different cell towers and to have a stable and fastest possible 4G+ connection. CellMapper app allows me to see connection possibilities with the various cell towers and their power.
Hello winol, I can't go back to my old Rom because I had a bootloader of 4 and now I switched to a bootloader of 6 so I can't go back :/)
