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.

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.

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

That's fine. Its only for one particular NVITEM. Just ignore it.
Hello varkey bhai,
Please Help me with the problem.
1. my meid is registered with reliance.
2. my prl is 00005

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 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?
I just installed the HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H14_AROMA-Installer.zip on my HTC Verizon M8. After doing so I can only get data via Wifi, it does not connect to 3g or 4g. I was wondering if this is a known issue if someone could direct me on what steps I should take to troubleshoot. I should mention that even though its a verizon phone I am using Smart talk.
Here are my current settings:
Preferred network Type: Global
CDMA Subscription: RUIM/SIM
Access Point Names : VZWINTERNET.
Network Operators : receive "Error while searching networks"
SIM status -> Cellular network state : disconnected
You used this version? http://forum.xda-developers.com/verizon-htc-one-m8/development/rom-vzw-stock-gpe-5-1-lmy47o-h9-t3212413
Did you do as the thread states:
[*] If you have issues with 3g/LTE data hand off, do a full RUU and do a factory reset with the stock recovery. Alternatively just flash the stock recovery and do a factory reset. Theory is the stock recovery rebuilds NV data. Getting a new SIM card has also been reported to work. Calling customer service and asking them to reset your connection has also been reported to help.
I'm having similar issues but I'm using page plus(Verizon network with Verizon m8 and only text and calls work but no data. Also using Verizon APN any suggestions
UPDATE: 4G/LTE wouldn't work without erasing all possible APNs except Ting's (with some messing around to get settings correct). LOS14.1 continued to throw errors with this install though so ultimately re-flashed with RR and it's working perfectly now.
--
I'm trying to port an S4 Mini SPH-L520 (CDMA) for use with Ting. Has anyone successfully done this with full access to phone, text and data? Having updated the carrier settings while stock, then flashed LOS 14.1 I've got functional voice, SMS, WiFi and can see 3G sporadically when I refresh network settings, but 4G/LTE's a no-go -- I get a "Your mobile data service couldn't be activated" error from the setup wizard every time the phone starts. It's definitely seeing Ting's SIM card because it's showing the correct ICCID, but won't work at all in RUIM/SIM mode ("No service", "Select SIM Card" with no options) and defaults back to NV. Haaaalp? I'm very computer literate but cell phones are terrifying and mysterious black magic...
