I have my Evo flashed to revol. I want to know where or what i can edit to make my phone only use 1x mobile data. When i turn off my WIFI i get the 3G icon for like 5 min then it finally turns to 1x and i finally get connections. What i want is to change it so it doesn't even look for 3G it just goes straight to 1x. Someone please help me find where this is located in the system. There has to be a file somewhere that has this in setting it. I have been looking for days now and cant find the answer. I have googled and searched on here and have found notta. PLEASE HELP
EDIT: problem solved in post 5
If you are running a EPST enabled rom. Just use ##3282# then EVDO change the preferred method to CDMA instead of automatic. You of course need to use edit and your MSL.
Under mobile networks on aosp you can force 2g only which is 1x or you can use 2g+3g or 3g only etc on cm7 or decks you cab use the notification toggle and set the mobile network mode to 2g only and off and when you enable mobile networks you will only use 1x and not evdo
We are legion, for we are many
Thanks guys for your help
Ok so if any one out there wants to force 1X data here is how.
1: Download a copy of QPST ( http://www.fileserve.com/file/xaJaa5z )
2: Download a copy of the newest PRL ( http://cid-eabe29f3770d8d15.skydrive.live.com/browse.aspx/.Public/PRLs )
3: install QPST
4: Using RL Editor in QPST open the PRL file
5: Under System Records find any that don't have 95(A,B)/1x as the system type and delete them.
6: Change the Preferred Roaming List ID to what ever you want it to be
7: Save the file
8: Copy it to your phones SD card
9: Use This method to update your PRL.
10: Reboot and you are done
REMEMBER to only delete the ones that don't have 95(A,B)/1x as the system type. Also don't change anything else as i don't know what might happen. If you run across any issues just update your prl back to the original.
Also i am not responsible if you screw up your phone. You are doing this at YOU OWN RISK.
Here is the newest PRL already edited for you: http://www.box.com/s/6s4bkj8cbv3bud8c7a47
This is the one i am using right now so it does work. You will know for sure it did by going to settings,about phone,network, and look at mobile network type. It should say CDMA 1xRTT. If it does then you are all set. If not then you didn't delete them all.
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.

Thanks for the above method .. Did you use this method after loading the NVDump file given by the registrar ? ... ALso when i edit the UM and AM feilds and issue write to the phone its showing as the phone has a read only NV ITEMS.

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.

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,

I have received a p607t tablet, it was flashed by smb. to p905 firmare (with no imei). i re-flashed it with stock P607TUVUBOI2 firmware (4 files, so-called "service" firmare), imei is back (to what is printed at the back-side) but mobile networking *still* doesn't work: no connection. I'm using not t-mo sim-card, but looks like the tablet was already unlocked
From service menu *#0011#:
SERVICE : LIMITED
NETWORK : UNBLOCK
IMEI Certi: PASS, 1
From Advanced Signal Status:
Carrier:
Network Type: Unknown
Signal info: n/a
Neighboring CID: no neighboring cells --- wtf? >> other devices work ok with this sim in lte and 3g modes<<
GSM service: emergency calls only
GPRS service: disabled
Any ideas?
OK, so, what is done with p607t to the moment:
1) reflashed CP (modem/RF??) to latest stock (P607TUVUBOI2)
2) reflashed AP/PDA (core system??) and CSC (consumer stuff??) to P605XXU1EOI5 (from p605, have one right here - it never had network-lock from factory)
3) using qpst and qxdm changed nv parameters (extended lte bands, enabled gsm rf-bands - there were none in stock at all, only wcdma)
now the tablet sees my local gsm network with this sim-card, signal is 4/5 bars, but still no internet connection - WTF??
p.s. when trying manually to register in my local network - it fails with "try again later"
p.p.s.: what is i find weird, in service menu *#0011#:
NETWORK : UNBLOCK
- this line exists only on p607 - is this the key?
Then, i insert this sim into p605 (completely stock P605XXU1EOI5) - it works like a charm
need some help - where to dig next? point direction plz
UPDATE. i've been tweaking 607t nv items with qxdm, making it alike that ones 605 has. practically everything is alike now, but still it doesn't even try to establish data connection with cell...((
btw, 605 does not have "esf embedded file system", while 607t has one (can be seen through qpst-esf explorer)
also, some nv-items present in one model, some present in another

I had to flash back to the original kitkat firmware and take OTA to upgrade to lollipop. There is a known issue with the 607t losing data after roms are flashed. Some had luck with flashing the same rom twice but it never worked for me. Used Sam mobile to pull original and went from there. Good luck
I performed "device init and reflash" with Keis. The device is back to stock completely, except:
- nv items data
- esf embedded file system data
so... my guess - i need to restore these in order to have mobile networking working.
could someone post a qcn-file with factory esf-data?
ok, let's take another way: how can i get some gsm-module debug-output or log to understand, what's going on it?
i'm trying to write some custom modem.bin to /dev/block/mmcblk0p2, but after reboot data in there is reverted to stock modem.bin - how come?? is that bootloader doing? where is the stock-one stored?
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?
Sent from my Nexus 6 using XDA-Developers mobile app
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.
Hello
Here is my issue: I buy a second hand S4 mini plus (i9195i - serrannoveltexx) for its compact size and by considering the simple usage I make of my phone. So far I do not use so much data so I don't care about used network, but recently I start using more data and I notice I never get LTE. I change carrier because I was thinking LTE-cover was the problem, but not. I still have no LTE. So below, is more or less everything I tested:
at beginning, I was few months on stockrom. Then I go to LineageOs 14.1 (thank to dev for the work). In both case I'm almost sure I had no LTE (I checked APN and 4g/3g/2g enable in network menu. And I start to check LTE-cover of each carrier . And I very start to check band used by the different carrier).
I change carrier and I check APN once more : still no LTE.
I come back to stockrom (just in case) : still no LTE
I switch SIM card : my sim card in Oneplus One get LTE and sim-card of my friend do not get LTE with my phone. (So I try copying manually the exact same APN : not working)
I try to flash old stockrom and let OTA update make the work : no LTE
I make necessary to have CSC=XEF as I am in France.
I try flash with pit-file and re-partition.
At the end, the best thing I succes to get was H+ (and for some reason I have it when I clear and restore the NV in 'service menu'), so :
-I contact samsung and they recommend me to go to one of their after-sales office.
-I contact my seller and he tells me that LTE works in germany.
Does someone has an idea how to solve this issue ? something that could block LTE ?
Next step I have in mind :
-I read some topic where double-flash within wipe and clear factory could help (but I have the feeling that will not work because it is more or less what have done to change CSC)
-I would check the activated LTE bands (but in 'service menu', I find a LTE band hexa-value that meet with explanation of binary description (another thread in XDA - thanks to people who write this tuto))
-I am considering go back to LineageOS but 15.
-I am considering to change LTE antenna (this is part of middle frame - I notice if I enable Data when i have 'service menu' opened, the phone seems to looking for LTE first, so I am not sure this is only SW problem ... do you think it is possible that only LTE part of such a SystemOnChip could die ?)
Thank by advance for your help

Some older Samsungs eg Note 1 had reception problems due to poor connection (possibly oxidised contacts) that could be fixed by simply tightening the screw a fraction that secures the pcb or antenna so it was grounded (from memory) properly, though of course it could be your actual antenna that has failed. (possible cleaning contacts might be worth a shot if tweaking screw doesn't fix)
(or modem/baseband issue if software, try flash again or try another version, backup your baseband radio settings first with twrp or an app)
edit: also try reset network settings before paying for new antenna (edit: though suppose flash with pit etc should have done this)
Hello,
Some news on the topic:
I try to tighten the screw and I also try to clean LTE antenna contacts : I use very very thin sandpaper (usually used to polish) to be sure there is no oxidation
I also make the mistake to erase all EFSs and EFS_Backup
Reminder : in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'NV backup test' / 'Erase all EFS 1/2/3' => So never do this if you have no backup
After this, I lost my IMEI... no way to restore it with IMEI tool... What a pity because I was hoping to only set my IMEI in order to test with completely clear EFS. Finally I restore my IMEI thank to my very first TWRP backup (thank to TWRP team that it works for me because it seems not always the case)
I try 3 times consecutive reset factory : 2 in recovery and 1 in settings.
I try to activate new LTE band but it seems that as I am in StockRom, update is not properly done.
In fact just after the work with QSPT and QXDM, I can find the nez band in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'LTE band & CA combination. but after reboot I lose it. Probably I'll make the work one more time after coming back to LineageOS.
One last thing I want to try is going in front of 4G antenna and check signal power seen by the phone but I'm thinking this is not the true problem. I explain:
service menu (*#0011#) start to show Basic network information and if I force LTE_only (in service menu), I can observe these information. strange thing I see are sometime state goes to 'TAU_init' (and also 'deregistr' or 'register'). Some other time MCC-MNC goes to 151515-1515. I have the feeling the phone is trying to connect but something goes wrong and I do not know what...
if someone has an idea, I am still looking for.
Best regards
