I recently bought a second-hand SGS, supposedly locked to 3. The firmware was from 3 UK, but when I punched in *#7465625# it showed all locks are OFF.
Hot for tasty Froyo, first thing i did was to upgrade from the branded Eclair ROM the phone came with to an unbranded stock Froyo ROM. Kies gave me a hard time so I used ODIN. Then I inserted my SIM and realized I could not make calls or even register on my GSM network. (Had not tried the SIM before, so I don't know if the flash caused this)
I found out that the flash had changed my Product Code to KOR, but I managed to change it using THIS GUIDE. However, the step "rm -rf /efs/nv_data.bin.md5" did not work as it was write/read protected. After reboot, the SIM didn't work so I did the "busybox chown 1001:1001 /efs/nv_data.bin". The procedure changed the Pcode to H3G, which I think is the original code, although I was going for XEE.
IMEI has not changed (*#06# gets same no. as is printed below battery)
I live in Sweden, my present CSC is XEE, Product Code is H3G. Network Control Key is 00000000, could this be related?
I considering doing the Product Code change procedure again and see if I can change it too XEE hoping that will fix it, but I'm not even sure this is related to my problem.
Other than that, I'm running out of ideas. However, I'm new to the SGS scene. I'm reaching out for someone with more experience to give me some new ideas.
I've spent hours and hours at this and I've googled like possessed. If I'm being a noob or have overlooked something, let me know - just tell me what I should do to fix this phone.
Go into Settings > Wireless and Network > Mobile Networks and check that Network Mode reads as auto mode. Then open Access Points Names and check that APNs are listed that suit your carrier.
If all of that checks out, go into an app like SGS Tools and use the secret code to check Band Selection.
Thanks for your reply!
I have inserted APN for data. Though, is this really necessary just for 2G calls and SMS?
When I choose "Select Automatically" in Settings/Wireless and network/Mobile Networks/Network Operators then I sometimes get "Registered on network". Then, when trying to call, I get "Data network not available". Band Selection (from SGS Tools secret codes) show:
= BAND SELECTION =
[1] AUTOMATIC []
[2] WSCDMA BAND []
[3] GSM BAND []
[4] COMBI BANDS []
When I select the network operator manually, I get "Unable to select network. Select automatically".
An alternative Go to Rom Kitchen build a rom with
XWJS8 > Hardcore Kernel >CSC CPW > Modem JPY and whatever else you require that should give all UK main networks .

I got Data Network not available when I was investigating my phone (that is, messing about) and changed my Network Mode. Go to Settings > Wireless and Network > Network Mode and choose GSM/WCDMA Auto mode. If you don't have connection, then try first GSM Only, then WCDMA Only...then back to both.
And yes, you need to have a data network connection to make calls. Not sure why. Must be something to do with billing.
I would hate to be right but are you sure, as you've bought it second hand, that it hasn't been registered as stolen? Do you know any history of the phone?
Product code should be GT-I9000HKDXXX, where XXX should be your CSC which is XEE that makes it: GT-I9000HKDXEE, you should not use H3G at all.
double post...sorry

Weird, I was sure APN is only required for MMS and Internet, not for calls and SMS. Anyway, I have APN so that's not it.

No, I don't and I can't be 100% sure it's not stolen. However, I have a bill of sale with all his information and I know where he lives so if that's the case, it can be sorted.

I think you are right, and I managed to change it so now both CSC and Product Code reads XEE, which should be correct for Sweden. However, the problem remains the same.
There is a possible solution from HERE, however it seems rather ...old. Having no other ideas I'll try it unless someone comes up with a better idea:
Richthofen said:
Possible problems (I had them all due trying different thing to solve it):
No service.
There is no service even a functional SIM card is inserted.
You cannot receive or make calls, receive or send sms, etc (obviously).
Freeze / lock-down.
The phone will not react to anything besides pressing power key.
You cannot unlock the display to enter PIN code.
Wrong PIN code.
The phone will not accept any PIN code on any SIM (even the correct one ).
Phone displays "wrong PIN code" message even the try counter (three strikes you know) does not change.
Product code changed to KOR.
= Blocked Kies updates (without a registry "hack")
Here is how to fix any or all of them:
Downgrade to I9000XWJM9 firmware with Odin (as usual).
Remove SIM card from the phone (to be able to boot in first place) and start the phone.
Gain root access and install "Root Explorer" (or similar), ADB works too.
Open Root Explorer and go to the "EFS" folder in the root.
Check the date on .nv_data.bak and .nv_data.bak.md5 files.
If it is earlier than 08/26/2010 you´re clear, if it is later then you may stop reading.
Once the date has been checked, select files nv_data.bin and nv_data.bin.md5 simultaneously and delete (yes, delete) them. Reboot the phone.
Now your phone is in the same condition (atleast permanent memory wise) as it was prior I9000XXJPC update.
There is a safety feature I would call "a dead mans switch".
If the current nv_data files are deleted, the phone will make new nv_data files from the .bak (backup) files (if they excist). The new nv_data files will be signed automatically so they pass the checks (none of the errors listed above will occur). However if they do not excist, the phone will just write an empty / test file (= IMEI corrupted, no service, etc). Also if you just rename .bak files they will have wrong signatures and the same problems will occur.
There is no bootloaders included, so it is safe to flash for everyone.

Have you tried doing a factory reset? May not work but may be worth a try.
Could only be either apn related (doubtful), faulty sim or stolen/lost phone. Unless hardware related.

Thanks, it seems a long shot but I will try it tomorrow.
I've already flashed the phone to XWJM9 with correct CSC folllowing the guide in my previous post. Restoring nv_data.bin and nv_data.bin.md5 from the .bak files didn't help, the .bak files were just three days old so the data there might have been contaminated.
As far as I can tell there's either a hardware fault, the phone is stolen, or I've messed up the precious data in /EFS by my first ODIN flash, before I did the back-up. Every guide should have that backup procedure as first step, mine didn't. :'(
I've mailed my operator so hopefully I'll get an answer tomorrow to whether the IMEI is blocked.
"No service" sucks...

Hi all,
I am a bit new to this forum. So my apologies for any tips that i have not known yet
I got a note 4 from SK telecom KR (SM-N910S) unlocked verion running Octa core version. There are 3 issues currently exist on my phone. I am living in Australia btw.
1 : Every time the phone start up, it will ask me whether i want to enable networking or not and talking about roaming ??
2 : Sometimes MMS can not be sent, retry few time and its ok ?
3 : The networking on SM-N910S has a big issue for me, that model only has 2 kinds of network LTE/3G mode or 3G Only mode, on AU version we have GSM/WCDMA/3G/LTE etc so it look like i am missing WCDMA and 2G networks
My question is :
* How can i access the hidden menu for Note 4, i know there is a hidden menu somewhere on that phone allow me to change network mode
* Can i flash my phone with AU firmware to remove roaming message and other SK's stuffs. ??
I can list some of my phone info here

I have got the same exact problems ! with my N910S
I flashed another rom it fixed some issues but i got some new issues with the new rom !
but only lil problems nothing major for example the calendar will have some additional chines calendar and the phone log wont show names if the number includes +61*****
I tired to post the rom but i have to reach 10 posts in order for me to add a link to it ! so i will probably post it by tonight

4G and LTE is just preference in naming. If you choose 'LTE' option without 'preferred', it will fail to fallback to 3G to make a phone call. Different story if your carrier has VoLTE

Are this phone n910s not support 900 wcdma band?
note 4 hidden menu network settings
I got this note 4 off ebay and it kept wanting to roam, and not use my network preference. I went into the hidden menu and changed it to all LTE and it asked if i wanted to use my network data and i said yes. Fixed it and the roaming "r" went away, but......................it won't stay like this after you reboot the phone, it goes back to roaming again until you go back into the hidden menu and do it again. How can you get it to stay permanently?
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.

I never updated past the 5.1 bootloader, so I haven't tested it, but if you try booting with the BP tools option and see the 3 devices missing drivers let us know.

Before doing this I had gone back to the 5.0.2 baseband to get band 12 back, but the wifi reboot issues were starting to get annoying. Being able to add band 12 to the later basebands is nice because I don't have the wifi reboot issues and it's much more stable.
This guide is awesome
Can activate all bands? xD or is bad idea?
Anyone managed to use the Verizon version on T-Mobile band 12?

Can I reflash the original stock rom to get baseband 12 back, before installing a cyanogenmod update?

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.

Are you getting LTE band 4 on T-Mobile currently? It might work. If you try it let us know.

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?

Band 12 was and still is active on the XT1526.
Band 12 was active on the XT1527's launch firmware, but was removed in the first OTA update.
The other models did not have Band 12.
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

Hi,
I am much interested in changing the LTE of YD206, has anyone suceed yet on this phone? A tuto would be really awesome! As I am new to android it would definitly help!
@TheArt. could you eventually translate the post please? My russian is far not good enought and google translated does not make much sens...! Did you succeed modifying the bands?
UNLOCK LTE BAND B20 - 800Mhz and B38
I will translate here the work of three 4pda users who must be thanked a lot for their work! unkernet, ssho and BoyNG. Thank also to mamant1988 who put everything together.
The original 4pda guide can be found here (in russian): http://4pda.ru/forum/index.php?showtopic=797643&view=findpost&p=59716629
UNLOCK B20 LTE BAND ON YD206
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.

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!

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!

GSM : 900 (E-GSM) 1800 (DCS)

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?
