Happy new year to everybody!
I would like to have a full backup from somebody who has SM-G906S of NV txt file with EFS professional because i want to compare with mine. I made a mistake and i think i modified also other values because sometimes my SM-G906S has full signal but if somebody is calling me it's like there is no network for 3G band WCDMA2100MHz.
Can somebody make upload here of his backup file (after backup edit NV 00550 to hide your imei).
I need also the original values of SM-G906S in one txt document of NV00441, NV00946, NV1877, NV2954, NV6828, and NV6829 to be possible to restore with Qualcomm NV Tools or can somebody help me to calculate again the values for all bands because i did a bad thing and now i don't have anymore GSM1800 signal - it shows Failed to register to network when i enter in network setting.
I need exactly help to calculate all NV fields for original config. of SM-G906S
2G - GSM900,DCS1800,PCS1900
3G -UMTS - B1(2100),B2(1900),B5(850)
4G LTE - B1(2100),B3(1800),B5(850),B7(2600),B17(700). In my country 4G is available in (B20)800, (B3)1800 and (B7)2600MHz. Even 4G for bands B3 and B7 is included in original network configuration of SM-G906S it doesn't register to the network when i enter 319712358 and pass 774632 for K version to access manual network config. (because i am using last custom firmware from xda) after i select the networks it shows (Failed to register to the network).
Thank you in advance !
Hi again,
I found the settings in this file "SGS5 SM-G906K v2.txt" on xda forum and i used the same settings only for the following networks 2G 3G and 4G. All frequencies are working except 4G. Everything is fine except sometimes if somebody is calling me, the caller can hear me but i cannot hear him. Even i use loudspeaker, i cannot hear the caller. This thing makes me crazy because i just bought this cellphone and i have already problems. I hope there is no problem anymore with NV settings. After this problem i restarted the phone and i was playing for a while selecting the networks from the menu and finally is working. Where could be the problem? Is there somebody else who has the same problem during calls?
I would try to use the settings from SM-G906S not from SM-G906K...
Thanks!
NV memory backup for SM-G906S
I had and i still have this problem with calls only when is selected in Automatic mode for network. For example, i select Automatic mode and then i make a call to other cellphone, then i enter in *#0011# to see the Status of the network and i see GSM900 and when it is changing itself automatic to GSM1800, i cannot hear anymore in the earpiece even in the speaker... nothing.
Also i see in the service mode pressing *#0011# GMM status: Registered/Normal and after a few seconds i see Suspended but the call is still ok until it is changing automatic to GSM1800. When i select manual to 2100MHz 3G everything is ok and also it is written GMM status: Registered/Normal.
I think the problem is still from that settings in NV memory, and what i did before, i did a big mistake... How can i restore again my NV data because i made a backup with QPST software download and failed and i couldn't restore NV backup... After that i found EFS professional which is working properly but it was too late because i already modified the settings...
Who can help me in this case who has one SM-G906S to make a backup of his NV memory.
Thanks!

Team,
***First off I am not responsible for damaged that occurs to any phones. Make sure you know what you are doing before making changes!!!***
I was having an issue with the mic gain recording distorted live concert audio so I was wondering how to access extended features on the Galaxy S.
The following is the code to dial in to access the hidden Service Mode menus.
Example how to access menus:
Dial *#*#197328640#*#*
This allowed me to adjust the mic gain to get better audio recordings at loud live concerts.
There seems to be several hidden menus on the Galaxy S and I am wondering how many more there are. Which led me to post this thread.
If any of you can find more hidden menus post them and i'll add them to this OP.
So far I know about:
Hidden Menus:
Service Menu: *#*#197328640#*#*
GPS Hidden Menu: *#*#1472365#*#*
Battery and General Info: *#*#4636#*#*
GTalk Service Monitor: *#*#8255#*#*
LCD / Speaker Test: *#0*#
Factory Data Reset: *#*#7780#*#*
Camera Information: *#*#34971539#*#* (Do Not Use The First Option "update camera firmware" you will break your camera)
Change Power Button Action: *#*#7594#*#*
Show IMEI Number: *#06#
Be careful in Service Mode that you know what it is your changing. If you hork up your phone you can reset it by doing a Factory data reset in Settings / Privacy / Factory data reset.
I would do a nandroid backup before making changes if your just experimenting.
I will add reference material below as I can:
__________________________________________________ __
Service Menu:
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Preferred Network types:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this.

Dude where you getting all these code. Nice find. You have any more? LOL
I don't which is which. I don't want to mess up anything on it.
Do you know how to work these setup menus?
Updated OP with more codes
I know how to get to the volume service menus in the phone, but does anyone know how to make the earpiece volume louder? My phone is too quiet when up to my ear (rocker volume maxed out) and I don't know what exactly to change in the service menus. I did it on my eternity but this one is a little different. any help is appreciated.

Several there that say RX, which one exactly? And what's the maximum possible value to make the incoming ringtone/text/email notifications louder? Thank you for all this, btw.

could it be that that's because the phone is locked and needs to be unlocked by the carrier

I found out that if you go into the dialer and type in *#*#197328640#*#* that it will take you into a menu that will allow you to change it. From the main menu of the ServiceMode screen, select DEBUG SCREEN, then PHONE CONTROL at the bottom, then UE STATE CONTROL. From there select CHANGE RAT TO WCDMA to enable 3G only, and select CHANGE RAT TO GSM for 2G only.

Give that a try.
YES!!!!!!!!!!!!!!!!
Thank you. That works! I've been trying for days to get it to work but it always stuck to WCDMA. THANK YOU.

Did we figure out how to max out the volume on incoming calls/texts? Samsung is notoriusly quiet.
What does this do??? (below copied from ealier post)

Turns off 3G, and uses only GSM and EDGE (2G) to save battery life.

I found a code on nother forum but can't remember where.. When entered it asked for a password and an IME number and one other number.. I found it by accident one day when searching for 'unlock captivate' and I think it brings up the same menu that is brought up when you use a foreign sim... Would allow unlock without requiring the insertion of a foreign sim..
Anyone know this code?
Hello,
I have a huge problem with my Galaxy S5 SM-G900F. I bought it abroad and when I used it for the first time in my country I saw, that there is a problem with 4G/WCDMA connection. When I put my sim card to the phone and set all the preferences in mobile connection menu to "Auto" there is no possibility to call or to recieve calls (even if i saw signal strength meter showing some marks). I can only recieve and making call when I set "only 2G" option and manually select my network. But signal is also very poor.
What I have checked yet:
1. Other sim also doesn't work good.
2. After *#06# i saw my IMEI and it is the same under the battery and on the box (doesn't start from "00") so i think that it is not missed (efs folder).
3. Change firmware with KIES and ODIN for the other version - no changes. Also flash some other "modem" files with Odin with no success in better signal.
4. When im on the free air the signal strength is even at maximum level, but immidiately after going to my house - there is no signal. I saw also, that when im in the city i can connect with 2G network (only), but when im on a village there is no signal at all (even 2G...)
Do you have any ideas what can be wrong? Is this hardware failure? Maybe something with antenna? What should I do before going to gsm service center? Maybe i should change kernel and try some of the custom roms?
Thank you for your help.
regards
Mario

Maybe there is a region lock? Does the Imei start with 35xxxxxx? Does the S5 support the local 4G bands of your provider? Maybe ask your provider for a new simcard. Correct APN settings applied?
My IMEI starts with "35....". Samsung S5 should be able to connect with WCDMA/4G LTE bands in my country. My sim card was changed about 3 months ago, so it is good - i have checked it in nexus 5 and everything works very well. All APN settings are applied.
How can i check if the phone has region lock? The phone is from UK and now I live in Poland.

You can check on the box. If is has region lock, there will be a warning message printed on the box.
Is there any warning message in the notification bar?
And please check as below:
While the phone is receiving LTE/WCDMA signal, open the Dialer, enter *#0011# --> capture screenshot (1).
Then press Menu > Back entry (not Back key) > Menu > Key Input > Q0 > wait for some seconds... > MAIN MENU > DEBUG SCREEN > NAS INFORMATION > MM INFORMATION --> capture screenshot (2). And then Menu > Back entry MM REJECT CAUSE --> capture screenshot (3).
And post these 3 screenshots.
I was able to connect to wcdma signal (I think) for some minutes. I give you all screenshots.

Is your network Polkomtel?
The error cause is: No suitable cells in location area - This cause is sent to the phone if it requests location updating in a location area where the subscriber, by its subscription, is not allowed to operate, but when it should find another allowed location area in the same network.
So may need to give this information to your network operator and ask them to fix.
So it is not the phone problem? It is my network operator error?
My network is Play P4, but this provider has no transmitters for his own in Poland (or has very few). He is able to use all of transmitters in Poland through the roaming (so teoretically i can connect with Polkomtel, T-Mobile and orange transmitters)
T-Mobile No Signal
Hi, este you able to fix your problem, ir so can you Please tell me how?

Hello dear XDA Community,
I have an american Nexus 6P (used with Verizon) which is currently used with a Russian cell carrier "MegaFon"
I had troubles with connecting to their LTE, for some reason my phone just wouldn't connect to the LTE and only stick to HSPA or HSPA+ even though an iPhone near me gets LTE signal just fine, the SIM card is fine in the other phone as well. So I started messing with my phone to find if I could fix it, first I started with going back to full stock, that didn't help, the phone still only accepted HSPA signal. Then I tried multiple ROMs and Stock Images but the issue of not connecting to LTE persisted. Then I found out about *#*#4636#*#* menu (aka Phone Info menu) and I started messing with it, which again did not do any good until I hit the menu button and pressed Select Radio Band (P.S. please don't mess with those settings) where I tried selecting all 3 different "GSM/UMTS" Bands. I tried USA band, Band mode 6 and Band mode 7, but this just broke down my signal completely, I cannot connect back to the carrier network no matter what I did. I've tried factory resetting, flashing radio img's, flashing stock/custom. NOTHING HAD HELPED/WORKED
I'm now stuck with a phone that doesn't work at all, and I'm on business trip so I'm just pulling out my hair for messing with those settings in the first place.
Does anybody know a possible fix to this? How could I go back to what I had before even though I tried all kinds of forms of factory resetting the phone
I really beg for your guys' help
Thank You
EDIT: Found this http://forum.xda-developers.com/nexus-6p/help/recovering-usa-band-to-auto-mode-4636-t3271347 gonna try that right now
EDIT2: That modified ROM helped! But I still don't get 4G
Have you tried removing the SIM card, rebooting the phone, then going into the Phone info menu and setting the preferred network type to LTE/GSM auto (PRL)? Maybe afterr another reboot with the SIM inserted the phone will connect.
Also check the APN settings -- they might have changed.

I think I've tried it, I'll give it another try after seeing if flashing this one ROM where you can select Auto Band in 4636 menu that I linked in the edit would work.
APN settings were fine.
Thanks
EDIT: That ROM helped! But I still don't get 4G
Looks like the post you linked should do the trick. Good luck!
code in Huawei *#*#4636#*#*
I have the same problem. My Huawei is Portuguese and the sms work and the internet to but no signal radio. Wen I dial a number tells me no radio found. Can somebody help me? Thanks
Good day
I am currently in Venezuela and I just received a Moto X pure literally just get it out of the box. When I plug the SIM on the device recognized it I could receive SMS and Calls but no data, no 3G no H+, no 4g. I double checked the APN and nothing. So I look some Info and found this app from the store called "Network" which i think its just a shortcut to the *#*#numbers#*#* anyway below there was an option "lte/gsm/cdma auto (prl)" i change this to other options to try to force LTE but nothing worked. So going desperated press the three dots menu on top and click "select radio band" and by mistake selected USA Band. Inmediatly lost signal and now the decvice doesnt recognize the sim card anymore. I tried to go back to this menu (select radio band) but the only options i see are "USA Band Cellular and PCS" none of this working for me. I ll really appreciate any help you could bring me cause i dont have a phone to replace this one. I also ask the moderator to move this post if this is not the right place for it, I ve been seaching for help but there is just too much information concerning radios, modem, and bands that i can really understand.
My carrier here is Digitel working with this bands
LTE 1800
3G 900
Hopefully you unlocked the bootloader and made a backup before messing with such things. If not, factory reset is probably your best bet.
thanks for the reply
I just did a factory reset and still the same... could flashing a stock rom help with this?
Likely reflashing the firmware will put it back to where you originally had it. If it asks you for a password for anything, it should be all 0's (00000).
