Hi XDA Gurus
I have an hw6925. It was unlocked by entering a code.
On the page for selecting my network I see a single button "Find Network". It gives no control to select a network by hand or to set a preferred network. I basically have only the top button of the three you can see in the attachment below.
In theory I should have those options... I have a hw6940 with those options and even the ATT/Cingular website for this model shows that I should have those options. (see http://www.wireless.att.com/answer-center/main.jsp?t=solutionTab&ps=solutionPanels&solutionId=54869).
The phone is also unable to detect that it is roaming. (The roaming triangle symbol never appears when I am roaming, and the activesync roaming schedule is never used.)
It is not clear to me why I am missing these options but I believe it may be because the firmware is not the last version. The Asset Viewer shows that the ROM is 1.30CIN.03ENG (bootloader G.39) and the Radio firmware is 1.02.00. My hw6940 shows firmware 1.48NA.00ENG (Bootloader G.39) and Radio firmware 1.08.00.
I really need to have these options so I am trying to understand how to upgrade my phone. There is no newer firmware for this model offered on neither the HP nor the ATT/Cingular sites. The HP site has the upgrade for both the main and radio firmware, but will not allow me to flash those to my hw6925.
I'm pretty technical but I dont have much experience with these HTC devices.
So, my questions:
1. Does anybody know a simple reason why I dont have the network functions in my hw6925? Is it because of the radio firmware? or the general firmware? or something else?
2. Assuming it is the firmware, any idea how I can upgrade it? Do you think it is possible to use something like HPRUU.EXE to read the radio firmware from my hw6540 and then load it onto the hw6925? Or am I likely to brick it that way? (Can I backup my hw6925 firmware, try it, and if it fails then reload the hw6925 firmware?)
3. Any other ideas how to convert it to a generic hw6945?
Your help is really appreciated!
Thanks

if anybody else finds this and needs to solve this problem too, I have found a solution.
indeed the issue is not with the ROMs.
there is some feature used by cingular to disable these features, and it is controlled somehow by the SIM card. you can see discussion of this in these two threads:
http://forum.xda-developers.com/showthread.php?t=284201
http://forum.xda-developers.com/showthread.php?t=266794
The solution is to edit the registry under HKLM\Security\Phone\, and set these values:
L: 0
ManualDisable: 1
PreferredDisable: 1
All three should be set to 0. (In my case I did not have a PreferredDisable at all, I added the DWORD entry just to be sure).
In the threads listed some people complained that these values were reset to 1 during reboot. In my case (with no cingular SIM, since my unit is unlocked) I did not have this problem.
Hope this will save somebody else a few hours of searching...

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...

I had cm7.0.3 running ok with radio:
October 2010: Radio_12.28b.60.140e_26.03.02.26_M - HTC WWE 1.32.405.6
I followed the instructions here:
http://forum.xda-developers.com/showthread.php?t=896597
to flash recommended radio:
4th January 2011: Radio_12.28e.60.140f_26.04.02.17_M2_SF - HTC WWE 1.72.405.3 R2
I'm not sure if it was because I didn't wipe but everything since was very jerky and the device was unresponsive, therefore I reverted to an older ROM I had backed up. Now I have found that I no longer have a 2g/3g data connection, the phone just states "unknown" within my quicker app settings.
Does anyone know why I've had this problem, or better still any ideas how I can resolve?
Punch in *#*#4636#*#* into your keypad and head into Phone Information.
What info is displayed? You may need to type it all out.
Cool, thanks for this info.
Right I have followed your instructions and before I write everything out I have notice that at the bottom of the first menu (which is: Phone info) the "set preferred network type was set to "WCDMA preferred", am I right in saying I should change to "GSM only" or "GSM auto (PRL)?
Mine is set to WCDMA preferred and I get 2G/3G/H. Try it, you have nowt to lose at this point.
Ok, changing that doesn't seem to have worked. I lost regular phone signal.
Phone info for you:

Does this help you at all? Thanks, appreciating your support.
It does a bit. GPRS service reads "Discontinued". If you had disabled data on your phone it would read "Disconnected".
What I would do is try the same SIM card in another phone. If you cannot try that you can check your APN settings.
Settings > WiFi & networks > Mobile Networks > Access Point Names > check you have the correct settings.
I can't try the SIM card part until tomorrow.
Prior to leaving work today I did check my phones APN settings against a work mates (since he has an unrooted DHD) and they appeared correct. Both phones has two Orange UK (-orangeinternet) and Orange UK MMS (orangemms).
I removed the SIM and battery and then re-assembled.
I have been changing things and then checking, now it states the following (with regards to the list I provided you earlier):
Phone Number now appears
GPRS service now states disconnected
and the GSM disconnects still states:
=========DATA==========
State: DcInactiveState
disconnected with last try
at 12:59 AM
fail because No Error
PPP sent: 0 pkts, 0 bytes
PPP received: 0 pkts, 0 bytes
this is all with "WCDMA preferred"
I have also re-flashed with the radio that was previously in the phone (26.03.02.26), but still no data connection...
The only sure fire way to find out if its your setup is to run the 1.32 RUU and flash back to stock. If you get data then its your system / radio / RIL setup.
If you flash back to 1.32 you can be fully rooted / S-OFF / etc again in about 1 hour.
Ok, thanks for that.
Just to provide a little more detail:
I had to downgrade before rooting to CM7-RC4, then I moved to CM7-final, CM7.0.2 and then CM7.0.3 before I decided to upgrade my radio from 26.03.02.26 to 26.04.02.17.
This is when I hit my data problem.
Since then reverted to an older ROM backup and I have re-flashed different radio's to see if it would come back to life.
I have now applied the CM7.1 update (since I guessed I have nothing to lose).
Tomorrow I will try and make time to drop to 1.32 RUU.
Am I right in saying the RIL is the tie-in between the software and the radio? It sounds like this might be my problem now?
I'll need to research the procedures to do what you suggest since I'm still pretty new to all this...
Thanks again, I'll let you know how I get on.
Yes you are correct the RIL sits between the Radio and software.
An incorrect RIL could be the cause. Have you tried flashing the recommended RIL?
Ok, thanks.
I have some time now to play with this, would you happen to know if it matters which order I do this in?
radio, RIL, then ROM?
Sorry for that, I found the answer to my own post, RIL last!
I have now re-flashed radio:
Radio_12.28g.60.140f_26.05.05.27_M3
and then applied RIL (using ROM Manager):
HTC-RIL_2.2.0099HM
Still had no joy.
Ran the 1.32.exe application to return to stock (it informed me that it was changing 2.36.405.8 to 1.32.405.6) and my data has returned! My voicemail icon has returned too!
Would be ace to have these with CM7!
Any suggestions on the quickest and more reliable way to get to CM7?
1. flash newer radio
2. test vm & data connection
3. flash cm7
Just to let you know that after flashing radio vm and data still worked and then going onto cm7.0.3 my data still works - fixed! Although, I have lost my voicemail Still happy though, thanks for your suggestions.
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

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

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?
Hello XDA...
Ive been reading up on this for a few days and im confused and curious.
My IMEI is showing unknown in about device / status and entering *#06# into the dialer shows / 17. The weird thing is 4g LTE, MMS, SMS, and phone calls all work. I got the phone off of eBay already Sim unlocked. Since then I have rooted the phone and updated to official 4.4.4.
I did some research and I read that the IMEI is stored in the nv_data.dat file which I do not have in my efs/imei directory. I use Root Explorer and I have it set to show hidden files. As I said I got the phone off of eBay so I don't know if it was unlocked using a code, a box, or if it was factory unlocked.
Here is what im wondering.
#1. When you sim unlock a phone does the nv_data.dat file disappear? (This might depend on the method? Maybe? IDK...)
#2. Does 4.4.4 handle the storage of the IMEI differently? If so how does it store it.
#3. Can I get the IMEI to show up again?
I do know my IMEI as it is on the sticker behind the battery along with the model number and serial number. But why android isn't showing it is really bothering me.
Additional Information that might help.
Model = SGH-I337 (AT&T Branded)
Android Version = 4.4.4
Rooted = Yes
Busy Box = Yes
Baseband version = I337UCUFNJ4
IMEISV = 17
Carrier = NET10 (Using NET10 AT&T Sim)
If additional info is needed please ask. I have tried to give all the info I could think of that would be useful to this question.
Thanks in advance for your time and patience.
