My phone was working fine for a week or so. I had flashed a Legacy SERO phone over to this phone. Suddenly today the 3g icon disappears and under phone status, the mobile network state is always disconnected and I no longer have 3g data or MMS. Voice and SMS work fine.
The original donor phone works fine too (3g / MMS).
I've tried:
- flashing back to stock
- trying to reprogram NVItems (HA/AAA/Mobile IP stuff) back onto Note 2 (I think they were already there and I didn't change them, but it still doesn't work)
- tried to copy the APN for the donor phone over: but I cannot find a way to program APN on the Note 2, and isn't APN for GSM anyway?
- tried to copy the PRL from the donor phone over: but I cannot find a way to program PRL (tried DFS 4.0.1.1, which cannot read nor write the PRL)
This is really frustrating without data, can anyone help?

If anyone else runs into this, here's how I fixed mine:
I believe the problem was a combination of APN settings and the phone trying to go into LTE mode (which I don't have as a SERO classic user).
I had to turn off eHRPD and manually force the correct profile to load. I did this with:
##3282# => MSL => Edit => eHRPD (turn off)
then ##3282# => MSL => Edit => Others => LTE APN Settings => 3rd option (LTE - Sprint OTA). Oddly, before this change, none of the three options was checked, that could have been the source of my trouble.
Put it on CDMA mode only.
No cdma/lte. That will not work
I am using a HTC One V CDMA (Virgin Mobile USA) in India on Reliance CDMA network. The phone was flashed to Reliance and everything is working fine ie I can make/receive calls/sms etc. 1x / EVDO credentials have already been written to the phone.
Now the issue is that I am not able to enable data or the data connection doesn't get enabled automatically. When I try to enable data it says "Disconnected because service is unavailable". But if I press the "Activate this device" button in the settings section, an activation screen 1..2..3 comes up, then wait for 3-4 sec, the 3G symbol gets displayed meaning its able to make a data connection. Now if I go back to the settings page and enable data it successfully connects, and I am able to access internet at EVDO speeds. But after some idle time, the data connection is automatically disconnected and to reconnect I need to repeat the above process. Even if I intentionally disconnect data and try to reconnect, it doesn't happen and I need to go through the "Activate this device" process.
I believe some sort of initialization is missing which is done during the "Activate this device" phase and hence I am able to connect. What could be the reason for this? Is it some setting/configuration that needs to be enabled?
Please pour your valuable tips to resolve this issue.
Thanks
Fixed the issue with auto connection of data, not sure what fixed it exactly, but here are the last changes that I made after which it started working.
You need to use the tool QPST (I used version 2.7.378, an older version didn't work) for this.
In the M.IP tab, disable all profiles except profile 1
Then edit profile 1 and make changes (check attachment)
Then in RmNet tab enable auto connect for device 0 and 1.
After that
PPP Config --> Um --> Enter user/pass as "net" (Req Pw enc should be unchecked)
PPP Config --> AN --> Enter the EVDO credentials given by the MEID registrar (Req Pw enc should be unchecked)
Please note that I got it working merely by trial and error and some of the above changes may not be required and I am not even sure why they are necessary , but with the above configuration I am able to enable data without any problem.

Well, I had loaded the NVDump earlier, but as I had mentioned it would connect first but if you disconnect or get disconnected it wouldn't reconnect.
Check if the SPC is correct, cause I never got any error like that.

OP, I am taking a HTC One V for my dad and plan to use it with reliance, could you please tell me what I need to do ?
I already unlocked and rooted the phone. Do I just walk into a reliance store or do something more on computer etc before going there ?

You are talking about Reliance CDMA right?
If yes you need to get the MEID registered, will cost you about Rs 500. Reliance store guys will not do it, have to get it done through some 3rd party provider.
It says Read only NV Items for me too

Hello varkey bhai,
Please Help me with the problem.
1. my meid is registered with reliance.
2. my prl is 00005
3. i am using the handset since 10 months.
4. evdo is also activated on my number.
But i am just getting 1x speeds.
Only thing i feel, i am missing out is on the username,Password,NV file,akey etc.
I have not received the above details from my reigstrar
Can u please guide me how this can be done to start evdo speeds.
Thanks in advance

Without the correct EVDO credentials, you won't be able to get EVDO speeds. You need to check with your MEID registrar.
NV dump is not really required and the same can be configured manually if you have the credentials as I have described above. Since you are able to make and receive calls, it looks like the Akey is already set.
so that means if i dont get the credentials from the registrar EVDO can never be started on this handset??

You could check with some other person who does MEID registration, maybe they can retrieve the credentials. But without it, EVDO will not work.

Simply by loading the Reliance PRL file, you should have voice signal, if not you are doing something wrong.

I don't think that would be a problem.
Make sure you are using the right PRL file.
No above steps required.
You must have flashed NV Dump already.
Your phone must be activated via *228 already.
Just perform below mentioned steps :
1) Put your phone in Diag Mode by dialing ##3424#
2) Get HTC Diag Mode driver if you don't have it already
3) Download DFS Demo version from DFS Website
4) Connect your phone with DFS, send SPC
5) Now, go to Programming tab -> Data ->
6) Click Read
7) At PPP tab, write "net" (without quotes) to SIP NAI, UID, Pwd field.
Restart the device and here you go, your device would get connected to internet instantly.

Keval,
I recently bought a HTC One E8 and am using Reliance CDMA on Slot-1 and facing this issue.
Would the steps jotted by you help me?
Thanks,
Vinay
I've been working on a fix since a long time now. If you are in SD community then you prolly know me. Anyway I was able to fix this on two of my phones and it's now working fine. I tested for 12 hours now. I'll also tell you in the end what problems I'm seeing. I'm also working on a fix for that.
I noticed that a service is started when the fallback happens but if I kill that service the network also dies. But if you follow the below method it safely starts a new service which kills the one that's responsible for killing the 4G/LTE
1. Upgrade your phone to 13B firmware
2. Root 13B
3. Now download Shortcut Master lite app from play store.
4. Now add these shortcuts to your favorites in the "Shortcut Master lite app". You can search for "LTE" and click on search button
LTEBandSelection
LTETestMain
LTE System Selection
CDMAPreference
5. Now click on "LTEBandSelection" and enable all the bands
6. Save and reboot
7. You now need to enable your data and turn off your wifi. Make sure your phone is in Global mode (in settings >> Mobile networks >> System select)
8. After your phone is rebooted open "Shortcut Master lite" app.
9. Now tap on LTETestMain
10. Select Click on CDMA preference.
Now choose Band preference and select "any"
P_REV_Preference ---> "MOB_P_REV 3
This is important.. EVDO Revision --> Rev A
11. "LTE Connect w/o IMS PDN" must be checked
12. Now go back to your main menu in shortcut master lit app
13. This step is very important. Changing the timeout is important. Tap on LTE System Selection
Except "Scan duration" add a couple zeros to all the other timers. For eg: T_mpsr timer (Min) is 200
The fallback timer will reset itself after reboot. But don't worry the configuration is already updated with the new value. For some reasons the shortcut master lite app is not picking it up.
14. Now finally click on "CDMA preference" in the main menu and make sure it has the value you set in Step 10
At step 10 or 13 your network should go away and your phone should complain about "no network". That's fine. just ignore the message.
Now finally reboot your phone. That's it. You should now have 4G LTE and it won't fallback to 3G or H+
The only problem is when I'm on a call my 4G LTE is dropped to 3G/H+. But after I hang up it goes back to 4G LTE after 12 seconds. I don't know if it's an expected behavior. But I'm trying to see if there is a fix for that.
I tested this with Tmobile. Make sure your APN settings are correct.
Thanks @motorhead_biker., you rock!!!
I am on rooted 11a, flashing stock back and then will go to 13b to try this out. Was waiting for this.....
Isn't this thread a duplicate of http://forum.xda-developers.com/verizon-g4/general/guide-fix-vs986-dropping-to-3g-h-4g-lte-t3272434? Can they be consolidated?
Thread closed as there is already a copy in General and that is where it belongs.

Hello,
i have some problem with my nexus 5Xwith cyanogenmod 13.
Problem was started when i download application Field Test for Nexus 5x/6p
In lte data menu i try change LTE On/Off and change disable and enable band 26 and 41.
From this time all LTE not working. - maybe some parameters was change in modem.
Serveral times i try reflash original rom and CM13 and reflash radio...
I install application QPST and QXDM and in NV browser i have on line : 06828 and 06829 value : 1786875150815
I dont now if this value is correct, but if i try put new value according NV calculator or some numbers from this forum, whitch i found. New values is saved in phone only while i make reboot the phone and LTE still not working.
Backup original NV values i dont have.
Can somebody help me please ?
Thank you
Thank you ...

Just a quick question. Why were you trying to change LTE On/Off in the Engineering Screen? Were you only trying to enable LTE bands or did you have a problem with your data connection? If you were having data problems before downloading the Field Test app, did you know there are some know data issues with CM13. Did you lose your LTE connection?
Also, what gave you the idea to download QPST & QDXM? Do you have prior experience with these applications?
Also, since you have CM13 installed on your 5x, did you try and restore a backup in TWRP that you have saved to see if it corrected your problem?
Which carrier are you with?

Hello,
thank you for your answare, and sorry for my english.
Before problem phone was new and all was worked, but i tryed make some changes, because i searching solution for changng band and editing priority for diferrent LTE band.
Now my problem with no connection on lte is solve, i write zeros to partition modem1 and modem2 from modem filesystem and modem itself after restart phone reset factory setting, but i dont now where modem took IMEI, because i think IMEI is save on this partition...
-----------------------------------------------------------------------------------------------------------------------------------------------------------
But i still dont understed why, after reboot changes on line ID 06828 and ID 06829 comming back originaly number .
Bestest solution for me wold be if i find in NV parameter band priority according signal strenght. Or some application (IN Phone) for disabling and enabling all LTE band without computer.
My most-used bands is : 800,1800,2600Mhz

Shortcut Master Lite in the Play Store will allow you to access the LTE Engineering to set band priority. Open the app and click the 3-dot menu In the top right corner. Click on "secret code explorer" and allow the list to populate. You will be looking for a numbered code like "3282” or "33284". Click on each one, select explore from the menu and look thru each selection. The one you will be looking for will say something like Sprint LTE bands editor. You can enable bands 25, 26 & 41 and set band priority. When asked to enter your MSL, enter 000000 and tap verify. You can figure the app out. It takes a little time to get used to how the app works. Good luck and let me know if you need any more help.
P.S. I dont know why you would start changing NV values without any experience using QPST & QDXM. You can make a mistake very easily. Be careful when making changes. I would start fresh by fastboot flashing the factory images, bootloader and radio and start over. Just my opinion.
What carrier are you with and where are you located?

Why i start Edit without experience ? It is easy, because i need get experience
Band 25,26 And 41 is not important for me.
I need disable and enable and set priority for 800 1800 and 2600mhz, quickly from the phone...
My location is czech republic and switzerland.
