[Q] Automatic LTE & LTE Hotspot

Has anyone been able to LTE to be enabled automatically after a reboot without going into the testing menu? Or get LTE hotspot to work?

Yep I've been using LTE
Here get root explorer
Go into your build prop
Look for lte.OnCdmaDevice
Now just replace Cdma to Gsm
So it should look like this.
lte.OnGsmDevice=1
reboot go into settings and change it LTE/GSM
I hope that helps. And LTE hotspot works

I didn't have the line "lte.OnGsmDevice=1" so I just added the LTE line to the end of the file. After I reboot and set LTE on in the Testing menu, then reboot again it doesn't stick
FYI I'm using the latest CM10.1 nightly.

You don't go into the testing menu. You go into the mobile network menu:
"After it restarts go into Settings, More..., Mobile networks.
A new menu option should exist called Network Mode. In this menu you can pick the default mode and change between then."

ohhh, i wasn't puting telephony in front of the string.
I now see the selection menu and it sticks with a reboot. I'll test the hotspot tomorrow.
Thanks everyone!

Unfortunately the AP while LTE is enabled still isn't working

Anyone?

I thought the N4 wasn't LTE enabled?

N4 is capable of AWS-Band-4 LTE

CM13 - LTE Enable

hi
how to enable LTE for CM13 or android 6?
or
for 5.1.1 (LMY48T) ?
how to get hybrid modem image...
thx all

For Android 5.1.1 you can use this flashable zip: http://forum.xda-developers.com/nexus-4/general/4-4-3-nexus-4-lte-lte-tethering-hotspot-t2416822

thx

Anyone have a solution to this yet? I have the hybrid radio on my N4 that worked great with CM12 (provided LTE), but now that I'm on CM13 I'm stuck on 3G/HSPA+.
The "LTE enabler" version 2.14 has a check to make sure you're on Android 5 before it does its thing, so it doesn't work for Android 6. Is it safe to disable this check? I'll have to dig into the script and see what it's actually doing. I think it just flashes a hybrid modem image and then makes the build.prop changes to make LTE work (maybe also adds some APNs? Beats me). Hopefully all that is the same on Android 6.

you can disable that check i was in canada for a while and i was using frank aosp 6.0 with lte enabled

Actually, I don't think you can. Looking at the "nexus-4-lte-enabler-v2.14" script that changed the network mode, it makes changes to this file:
/data/data/com.android.providers.settings/databases/settings.db
However, that file doesn't exist on my Nexus 4 running the 12/30/15 nightly. Only "settings.db-backup" and "settings.db-journal" reside in that directory, and nothing else.
Did the preferred network setting move to a different DB in Marshmallow? I also noticed that if I enter the service menu via *#*#4636#*#*, I cannot change the Preferred Network Mode there (I can open the dropdown and pick something, but it doesn't change the "WCDMA Preferred" setting when the dropdown closes. It does nothing.)

Cm13 has a known bug , somebody forgot to put an entry into the framework apparently. The radio won't switch. See the thread over here ;

Any update on this? I see that the radio switch issue fix got merged a few days ago, and I do see in my build.prob that my preferred network mode is "9", even after rebooting.
But my phone always shows H+ or 3G next to the mobile data icon on the taskbar. Even if I go into the 4636 menu and change to LTE/GSM or LTE/CDMA (which I can now do because taht bug was fixed), it STILL shows H+ or 3G (and frequently rapidly bounces between H+ and 3G).

The fix has been merged , 5th of january or later builds don'T have that bug. But i've seen some corrections on the code suggesting that wcdma and gsm should be enough. If they merge that then we won't be able to use LTE. 3g and gsm would be fine though.

Anyone figure out a way to enable LTE on the Nexus 4 in CM13 yet? Really don't want to use some random guy's AOSP custom build if I can avoid it. I want CM features!

So after hunting around, i decided to check why the LTE is not persisting after reboot and tried and old trick: change the build.prop to READ-ONLY and remove the write flags in any file explorer (ES/ROOT etc)

It's not that LTE doesn't stick on reboot. It's that it cannot be enabled AT ALL in CyanogenMod 13.

Can you tell me what CM13 build you're using at the moment, and what your build.prop looks like? If you don't mind?
No matter what I do, I cannot get off of 3G/H+ on CM13. Not in the 4636 menu (I can change to LTE/GSM auto, but no effect), and not in the Cellular Networks settings (only choices in the GUI are 2G and 3G).
I had no problem using LTE on CM11 or CM12. I'm on the same hybrid modem image I've been using forever (2.0.1700.33).
Thank you for your help!

So I think I have figured out what's going on. After loading CM13-20160210-nightly, I did *#*#4636#*#* and changed "Set preferred network type" to LTE/GSM/CDMA auto (PRL), turned off then on the radio and saw only H+ come up. I clicked the options menu (top right 3 dots) and under "Select radio band" i noticed that the LTE Frequencies are not listed!! I added the 3 lines manually to build.prop then saved it as read only too just in case but it did nothing so I think we know why the LTE isn't showing up now. Only AUS, USA, Japan, Cellular and PCS band are in this build.
Could this explain anything by chance?? It seems only GSM frequencies are available.

FYI adding the lines to build.prop and setting it to read-only doesn't work for the latest CM13 build. I hope LTE is supported soon in CM13.

Take a look at query.sh script in Nexus 4 LTE enabler 2.13 zip. Script deletes and inserts 2 records in settings.db database.

[GUIDE] Enable LTE bands on surnia

After some trial and error I was able to successfully enable LTE band 12 on my xt1527 with the 5.1 baseband. This procedure only seems to work with the stock ROM, but then after it's done you might need to install a custom ROM like Cyanogenmod to actually make use of all the bands. Many people have done a lot of previous work to make this possible and they deserve credit, so don't forget to hit thanks on the linked threads. It might be possible to unlock different bands on the different models depending on what the radio will support. I have done my best to try to make sure that this is thorough, but there could be errors, so please let me know if any of the steps need to be revised or corrected.
**** Please note that by doing this it may be possible to permanently damage your phone, make it unable to access mobile networks, or cause radio interference, so you are doing this at your own risk! I am not responsible for any problems! ***
1. Be on a stock ROM (only tested on 5.0.2 and 5.1, see forums for how to restore stock ROM if you need help) Update: also works on 6.0
2. Make sure the Motorola Device Manager is installed https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
3. Select "BP Tools" from the bootloader menu (power off, hold vol-down, power on). The phone will look like it's booting normally.
4. You need to enable usb debugging in developer options. In Windows device manager you should see 3 USB devices without drivers loaded. I picked the first device and updated the driver by selecting Browse computer / Let me pick, and selecting Ports (Com&LPT), Motorola, Motorola QC Diag port. See this post for more info http://forum.xda-developers.com/showpost.php?p=54338876&postcount=3 You should now see Motorola QC Diag Port (COMx)
5. Install QPST and QXDM from steps 4 and 5 in this thread http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
6. In QXDM select Communications and you should see the COMx that you saw in Device Manager. Make sure the Target Port has this COM port selected as well. If it's not connecting double check that the driver is still loaded in Device Manager.
7. In the View box select NV Browser towards the top of the list, and in the window that opens choose LTE for Category filter.
8. The value that we want is in location 6828. Click on it and choose Read. Write this number down in case you have a problem! Convert this number to binary (I use Windows calculator) and these are your current LTE bands. Read from right to left and 0 means the band is disabled, 1 is enabled.
For example, the xt1527 has LTE bands 2,4,5,7, and 17 per the Motorola website.
The value in location 6828 is 65626, or 0001 0000 0000 0101 1010‬ in binary.
Code:
Binary Value 0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 1 1 0 1 0
Active Bands[B] - - - 17 - - - - - - - - - 7 - 5 4 - 2 -[/B]
All Bands 20 ? ? 17 ? ? ? ? 12 ? ? ? ? 7 6 5 4 3 2 1
As you can see from this example, each bit corresponds to an LTE band being on or off. Different models (xt1521, xt1528, etc.) will obviously have different bands enabled. To help fill in the missing info on the bands please post a reply with your model, the value of 6828, and the bands that your phone supports according to Motorola.
To enable band 12, I changed the bit in that position to a 1 and converted the entire binary number back to decimal.
Code:
Binary Value 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 1 1 0 1 0
Active Bands[B] - - - 17 - - - - 12 - - - - 7 - 5 4 - 2 -[/B]
All Bands 20 ? ? 17 ? ? ? ? 12 ? ? ? ? 7 6 5 4 3 2 1
So this new binary number 0001 0000 1000 0101 1010 = 67674 in decimal.
9. After you have calculated your new value, type it into the 6828 input field and click Write.
10. Reboot to recovery, make a backup of the stock ROM, and then install your favorite custom ROM, such as Cyanogenmod. The stock ROM might still restrict bands even if they have been enabled in the baseband. You can use the LTEdiscovery app to check your bands, and there are probably other apps as well.
11. If you have any problems try writing the original value that you wrote down earlier back into location 6828 (you did write it down, right?). If that doesn't work, see the modem thread, or extract NON-HLOS.bin and fsg.mbn from your stock image and flash them using the following commands in fastboot.
Code:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
Good luck, and don't forget that with the extended range LTE bands you might have data but not be able to make a voice call. You would have to go into Network settings and change the preferred network type to 3G to make an emergency call. Maybe a future project will be looking into putting the baseband from other SD410 devices that support VoLTE on surnia and then using this method to set the correct bands... Something to think about.
Update 17 Oct, 2016: Unknown bands have been replaced with question marks. Driver and utility installation instructions have been updated.

I think this is a great tutorial! I wonder if by adding the USA band (which I have achieved in the past) other carriers could be used? Just thinking out loud.

It's possible to make changes to 2G/3G bands also, so it might work if you add the right bands and the radio hardware supports the frequencies.

First thing i thought..
I was assuming this was a hardware issue more than a software config issue.
I had done similar on phones before too so i see what your doing
but i had no knowledge on doing this with more recent phones.
I use to use com ports with QPST (a Qualcom leaked tool) and some other phone tools..
to clone my one pay/go phone from one company to another or vice versa.
I cloned them back & forth because sometimes i bought the wrong type of minutes LOL
For example i had my favorite phone from Telus and i sometimes used another one from Virgin
Different phones totally Samsung + LG and both ran very different systems too.
But get this..
I actually cloned EVERYTHING.
Data settings + MEID / Phone # and even managed to get free unlimited TX messages which were suppose to be 50 cents each. HAHAHAHA
I told my brother and his wife and they laughed and he said you got it on you?
I pulled out both and he phoned then txt'd me
And both phones received the call and received the TXT simultaneously.
So.. OP
Thanks for the info i might want to play around with that sometime.
I had struggled losing LTE support to on my Canadian Telus phone before after using US retail firmware.
I had to put it into 3G mode
So i am curious if this will actually work properly though.
Just because you change a setting does not necessarily mean there is actual physical hardware support for it.
I learned something i think here cool good work!
I like the manually installing Windows Drivers tip too.
I tried side-loading for the first time the other day and i had to manually install the driver for it to work.
So lets see if people come forward proving this works.. i hope so
EDIT:
I will be clicking Thanks simply for showing me what the "BP Tools" was for hahahha

I talked with a sprint rep, according to him, anyone on my particular carrier (sprint), needs an msl code to change two specific values (I can't remember the names right this second) to reprogram it to a different carrier. I'm not sure about it, but there it is if anyone wants to give it a shot. I think one of the values was mdn, if that helps.

Wondering if it works on the Marshmallow update too ?

QPST will interface with this phone also, but it seems to be out of date because it doesn't read the full range of NV values. It would probably work for making 2G/3G or other changes like you mentioned, but it wouldn't read any LTE related values.
BP tools probably stands for "baseband programming" or something similar.

You can use an app like LTE Discovery to check when you are in a known band 12 area. I have an area near me that I drive through frequently surrounded by farms where I get a strong band 12 signal, but basically no service if I just have band 4. You could also check the value in NV location 6828 and use the method in the OP to calculate your current LTE bands.

That should work, but CM13 works best with 5.1 and newer basebands. You will likely have wifi and reboot issues. That was the whole reason for finding a way to add band 12 to newer basebands.

Probably a bad idea. The RF hardware in the phone can only physically support a few different frequencies, and it might vary by model, so probably only Motorola and Qualcomm know what will actually work. Best case if you try to activate all bands would be you just don't get a signal, worst case maybe you melt something in the phone radio, or get agents from your government radio frequency enforcement agency show up in black vans and take you away.

Did everyone have them? and across all the various original modem firmware?
Also amongst the firmware that have band 12 is there one that was more up to date then the others?
Band 12 got stripped out of all the 5.1 firmware and all the 5.0 or older firmware had band 12, which probable
means no right?

Yotaphone 2 signal boost trick/unlock band ?

Helo from Slovenia,
perhaps i found a way to boost signal or unlock bands in Yotaphone 2.
Go to android secret menu *#*#4636#*#*
Then go information about phone menu and scroll down.
There is a option for choosing priority band, normaly its choosen LTE/WCDMA
Klick on this and switch the options to TD-SCDMA,GSM/WCDMA and LTE or TD-SCDMA,LTE,CDMA,EvDo GSM, WCDMA
Now watch the signal boosting
I checked same locations driving yesterday and today with car. Where i yesterday got no signal, today i got fully edge signal.
And no signal outage today no matter the location
Check this option and let me know if it works there too. I tried on Android 4.4.3 and 5 work both.

I put the first one, but how can I see the difference? the problems was not getting the 2G signal at all if I force in 2G. But if I force it now, your suggested settings will change.
What is the difference between TD-SCDMA,GSM/WCDMA and LTE or TD-SCDMA,LTE,CDMA,EvDo GSM, WCDMA?
May I ask you which mobile operator you have and which radio & firmware you use on your YotaPhone2?

you have to go to spots/locations where you got no signal before and try it now ?

Setting your phone to the wrong settings so it fails over to 2G will no doubt improve your signal strength no end. But personally I would prefer to get fast internet on the move, and leave your radio settings well alone!
There are apps you can get that are called 'signal boosters' they just work by turning off your phone radio and then on again. If you were not connected to a nearby cell but one farther away this will 'boost your signal' ...
You're probably experiencing either or both of these effects. as well as the 4G effect - which is that if you have a local 4G aerial all the cellphones that can do so will be connecting to that, leaving you free to connect to an empty 3G cell instead with lots of bandwidth. Maybe not what you had planned to do, but actually improving your performance by setting the wrong settings

Did anyone already find the secret USB menu code to put the device into Modem mode? As the YotaPhone has a Qualcomm processor, this could be used to enable additional LTE bands, which really would help with reception like in [GUIDE] Add all GSM and LTE bands to your phone.

seems cool! We have to test

Starting point is a rooted YD206 with latest RU 134 firmware, TWRP and ADB-USB-debug enabled. Do this procedure carefully and write down all the modifications and default values. The changes are performed on NVRAM level, so flashing firmwares will not affect them. Flashing firmwares will, however, affect modified baseband, as any other "radio" part as usual.
Download here the .zip archive which contains what is needed for this guide, including some screenshots of how things should be displayed.
Download the modified baseband RU-CN here and put it into the internal memory of the phone: it will be flashed in the end.
Install QPST and QXDM Qualcomm programs on Windows, they are in the above archive.
Enable the installation of unsigned drivers in Windows (like this). This is needed to install drivers for the diagnostical port later on.
Download Terminal Emulator from Play Store.
In the Terminal, write the following to get root access:
Code:
su
then:
Code:
setprop sys.usb.config diag,adb
Connect the phone via USB to the PC, in the Device Manager it should pop up as "Android Device" or similar, without a specific driver.
Right click on it and perform these actions: update drivers, search on this computer, choose driver from already installed drivers, show all devices, next, install from disk, there point to the .inf file corresponding to your system (32bit -> x86, 64bit -> x64) found in \YotaLTE\Modified HTCDiagDriver\Win x64HtcUsbMdmV64.inf (for 64bit).
After installation, go to properties of this new driver HTC USB Modem and check the number of the port displayed there, COM3 or COM4, for example.
Lower the 38400 value which you find there, click OK.
Execute as an admin C:\Program Files (x86)\Qualcomm\QPST\bin\QPSTConfig.exe.
Choose the second section Ports, then "Add new port".
In the field Port put the one which was displayed in the modem section, COM3 for example.
In Port Label field write "Yota" or whatever, and then OK.
In the first section Active Phones the smartphone should be displayed.
KEEP QPSTConfig.exe PROGRAM OPENED.
Also, start C:\Program Files (x86)\Qualcomm\QXDM\Bin\QXDM.exe using admin privileges
Here, click Option, then Communications.
In the Target Port choose the same port as before, then OK.
Click View, New, Common, NV Browser. In the Category Filter choose LTE.
Choose 06828 LTE BC Config and then press "read".
Correct the number you see, for example 1099511627781 in 1099512152069 for B20 and click Write to save.
Close all the programs, and reboot the phone directly into TWRP (VOL UP + POWER), here find the update_S01_003_4240_RU1_M05_patched.zip baseband and flash it.
At this point it is advised to clean dalvik cache and cache with TWRP.
Done! Reboot.
If it is not working, reset everything by flashing stock baseband, putting back the values changed above and start again. It is not necessary to flash the modified RU-CN baseband, if with the CN one the phone is performing at 100%. I suggest to flash to see the differences. By the way, remember to unlock one band at a time.
To unlock B38 band (there is lack of information about YD206 already having it or not) the number is 1236951105541. For example, if the initial number found in LTE config was: 1236950581253, it means that the bands LTE B1/B3/B38/B41 were active. To verify by yourself download LTE Band Calculator.
Some attempts have been made also to unlock B7 band, but without success for now. It seems that the baseband crashes after a second when triying to connect to that LTE band. Further research needed!

After all the hassle I just went through to obtain a YD201 instead of a YD206 so I could have Band 20
Great news for YD206 owners anyway, thanks for sharing!

Me too.
Tried drivers installation with a yd201 (just for take a look about the wifi issue) and they are not compatible.
I guess modifying the inf files would do the trick.

Hi, I try to unlock LTE band, but su command doesn't work in terminal .... it said su: not found.

Do you have root? Do you give root permission to Terminal Emulator?

Just did the procedure, can't confirm if it's working on 800MHz B20 yet because I can't find a way to force it or even know if its available in my region from my Network, because I live in the city and they use mostly the 1800MHz, 2G Only works correctly and it seems that somehow it also solves the Proximity Sensor, I will give feedback at how it behaves tomorrow when I will be on the move, but until now everything seems well and smooth, Many Thanks for the persons that worked on the fix, I guess Yota should be hiring! And to @TheArt who translates all the good stuff!

band17
Hello,
Would it work to unlock band 17 At&t? Is that enough modify config 6828 number by calculator?

Hello,
I am from Bosnia and got Yotaphone 2 from China (YD206) and installed latest RU software 1.132, but I noticed that my phone only works in big cities. As soon as I leave for the countryside, there is no signal/service.
Is there another version of software I can try to upgrade to, to get these bands in the countryside as well, or the problem is with the limitation of phone's hardware?
Thanks!

Whats the coverage in your contry?
Maybe outside big cities there are not mobile connection in the frequency that yotaphone can support

GSM : 900 (E-GSM) 1800 (DCS)
UMTS: B1(2100) UMTS B8 (900 GSM)
That is what I found out from google. I am not sure what is the better way to find out what Yota covers and what is available here.
If someone knows please let me know.
If I perhaps flash the phone with EU software rather than RU which I currently have, would that unlock some bands?

Network problem or poor network on Jio try with band selection

If you are facing problems of poor natwork whatever network on are u there is something for you to get Best network coverage
There are money tips n tricks are making round all over the internet
I'm also the one of them who has searched n searched on google about jio network
Than i found artical about network band
Band 3(1800)
Band 5(850)
Band 40(2300)
All above all are Lte band is jio provide to us
In my case I'll always get band 40 it's slowest band in my area why beacuse a phone automatically switches between band according to the strength of the signal in different locations
So 1thing i know that i have to control my network band or lock band 40
Than i searched and searched on google
I have read lot of article about changing your band easily
Read about different code for different mobile
For example *#*#4636#*#* or phone info to select network mode lte only nothing change same result
Than shortcut master to creat "service menu" or "Engineering mode" still no luck with different 2 device
Than *#001# it's work but can't change or lock anything
Than i finally found on Xda a magical code *#2263#
this is really magical code for Samsung devices
If it is work for you than you don't need any apps or U don't need to root your phone
Stil no luck
It doesn't work on my phone
Than searched about how to make this code to work i found small artical on xda and it's work
But you need root to access system file this guide is not work for non-rooted samsung phone
i have just tested on my s7 cutome rom of kill-switch black diomaond v7
So u need esfile explore
To perform this action
In Esfile explore goto
System/csc/etc Or System/omc/INS itc
Now look for the file name with
INS_keystrings.dat and rename it to something like xyz.keystrings.dat
Now go back to System/omc/XXV/etc and copy the xxv_keystrings.dat and paste the same where u have change file name
Omc/ins/etc and rename it INS_keystrings.dat now reboot phone
And U will see *#2263# code will stated to run
Now u can chhose any band you want or lock any band which u don't want
Note:-- what if you dont have xxv or sin csc than you look for xxv or sin csc and flash it
I think it will work without above trick but it doesn't than do it manually
