AT&T Tilt Internet Problems on other carrier

Hello Everyone...
I want to first than everyone in the forum for all your posts.. With your help I have SIM unlocked my AT&T Tilt phone to work with my carrier (Einstein PCS).
I am not new to Smartphones.. My first being a Motorola MPX220 that I used a modified rom to have 2003... After that I had a iPaq 6515.... Now I have my Tilt.. I did a hard reset when I got it and rebooted near the end to precent all the installation of much of the AT&T bloatware... I got the settings I needed for my carries internet... But it seems to only work sometimes.. If I am simply web-browsing it is great, or using software like IM+... But when I try to run updates, or TomTom Traffic (among many other things) it does not work and seems to try to be connecting to AT&T or something to that effect. If I am connected via Wifi everything works fine. This becomes very irritating as I can't be connected via Wifi and be driving around... I loose the signal and there aren;t always Wifi hotspots available. We have bad traffic problems in this area and the TomTom Traffic usually helps reroute it well. Any suggestions? As I said, some stuff works, other stuff doesn;t. I will include the settings I got from my provider below. I also manually delelted the AT&T settings in the conenctiuon manager thinking that would help.. it did not.
under proxy settings check: this network connects to the internet
check this network uses a proxy server to connect to the internet
proxy server should be :192.168.254.251
click advanced
http: 192.168.254.251:8080
wap: 192.168.254.251:9201
secure wap: 192.168.254.251:9201
socks (blank)
under modem, your access point name should be : apn
name and password blank.
under advanced check use server assigned ip address
Those are hthe instructions given to me by my provider.. ANY help would be greatly appreciated! My carrier chargs me about $50 a month for unlimited Voice, TXT, and Internet, so I want to stick with them. (BTW< I am also having problems using MMS messaging).

First of all, you might want to look into installing the OEM htc rom... The ATT rom has hidden proxies that might be causing you issues, besides, you dont really want all the ATT bloat to begin with since its not going to work with your carrier!

Thanks for the advice.. but I had read people are having problems with the GPS chip when they do that.. is that correct? I downloaded a few of the roms, but not sure on how to install them, or to even know which would be best for me.. Any suggestions? Also, any step by step walk through on how to install them exactly? Preferabley something that will work with Vista as I run x64 ultimate... IF not I can get acess to an XP machine.. but not as easily... Thanks in advance

Many people, myself included, are using unlocked Tilts on other networks without any problems. It's hard to say which rom would be best, it's really a matter of opinion. No doubt, you will have to read...and I recommend you start with the wiki. All the info you are looking for is covered there.

this will give you a link to the official HTC rom
The people you read about with problems on anything are usually using cooked roms or using an incompatible radio. But for YOU, i would suggest using the OEM rom which is linked in that thread i gave you..

[Q] HTC Desire HD WiFi not connecting at house but does everywhere else

Hello. My phone connects when I go to other people's houses or at school, but not at my house. My router is set up with a WiFi access list so that you need to enter the MAC address before being allowed to even see the network. I have triple checked that the WiFi MAC address from my phone is entered correctly as I did everything else. Does anyone have some advice?
I appreciate everyone's time!

Make sure the channel is set to one which your device supports.

I downloaded an app called wifi analyzer; will that help me find which channel to set it to? How do I know which are supported.

Go to the wifi settings (on your device) and see what channel it is set to (usually under regulatory domain).

maybe you should set the maximum number of channels, otherwise some routers might be excluded.
controls which channel is your router and then try to configure the connection manually.

Sorry for the late reply; I have been pretty busy.
I tried a variety of different channels but none of them seem to work. I had seen that the phone does not work on Channel 13 but that did not seem to be the problem. I have also tried changing the security password type on my router but that did not work either. Are there any other suggestions? Thank you again.

your router is wireless network is to advanced for phone allow you network to be seen and just have to enter a password to work it will work been there
ps when it works hit thanks please

I'm assuming you did... but just in case, you did hit the "Wifi Protected Setup" on the phone right?
I swear i'm not trying to make you sound like an idiot, but we all have our "oh damn i forgot about that" moments, know what i mean? lol

Lol no problem. But yes I did do that

i'm also assuming then that you took ALL security off your network, leaving it open with no password, and that didnt work either.
past that, I don't know what to tell you. some routers are better than others.... maybe yours just hates you?

HTC Thunderbolt on PPC with 3g without using CDMAWS paid version

Ok everybody, after a few days of tinkering around with the help of many different forums and threads (sorry, i cant possibly start thanking individuals cuz i went through so many threads) i finally got my htc thunderbolt on PPC with 3g working. this is how
1.) remove the 4g sim card (if you have it) from the thunderbolt
2.) aquire all of the drivers you need for the thunderbolt and DM mode (hint, use htc sync)
3.) on the phones dialer dial ##3424# and press send
4.) hit the button that says reboot to modem+diag mode
5.) when your phone is plugged into the computer, has all the drivers installed, and is picked up in the device manager as 2 com ports
A.) The voice, text, and 1x com port is the htc diagnostic
B.) the 3g/4g com port is htc diagnostic 9k
6.) aquire a copy of cdmaws (2.7 is fine, there is a cracked version floating around, just use google no warez links
7.) open up cdmaws and connect to the non 9k port and connect
8.) go to the security tab and input your spc (000000) and click send, should say unlocked
9.) go to the other tab and under R-UIM Config make sure you select NV only then click write
9.) write all your nam settings, mdn, min, sid, nid, imsi and etc etc (other posts here at xda have all the details) repeat for name 2
10.) go to the other tab and under prl make sure it says universal and nam1
11.) click write and locate your pageplus evdo prl file (i used 51720) repeat for nam2
12.) go to the main tab and click disconnect but DO NOT CLOSE CDMAWS!!!!!!!
13.) connect the 9k port and repeat steps 8-12 but dont read, just write (all of your settings should still be on the screen)
14.) close cdmaws after all the settings are written to the phone
15.) find a copy of qpst 2.7 build 366 (again, google is your friend) and install it
16.) open up qpst configuration and click add new port
17.) find your non 9k com port click it once then click ok
18.) at the top go to start clients->service programming
19.) click ok then click read, click ok on the pop up that comes up
20.) go straight to the m.ip tab and create a new profile (or edit the one that shows up if it shows up) make it look like the screenshots i have below
21.) write the profile
22.) go to the PPP config tab and put *your 10 digit page plus phone number*@vzw3g.com for your nai and *your 10 digit phone number*@dun.vzw3g.com for teth. nai. password is vzw for um and an tab.
23.) close service programming and select the com port in configuration and remove it, close qpst configuration
24.) get a copy of dfs tools (demo is perfectly fine)
25.) see screenshots included at bottom of post
26.) make sure you start with the non 9k port, write what you need. and change ports to the 9k port without closing dfs tools, write everything to the 9k port (to be sure i pressed write for everything about 30 times but i may have been a bit excessive
27.) now activate the thunderbolt on your pageplus account by taking the last digit off of the imei number and they'll take it.
28.) insert ANY sim card into the sim card slot (NOT A VERIZON 4G ONE) i used a old nextel one to be honest
29.) turn on phone and dial *#*#4636#*#* and click phone information. change to cdma auto (prl) and close out.
30.) make a phone call and BAM 3g picks up and authenticates
Sorry if this guide isnt easy to follow, im not too good with wording things, lol. but it gives enough info for others to help including me.
also make sure under wireless and networks-> mobile networks-> that data roaming is allow for all trips, network mode is cdma only, and system select is automatic b
feel free to post to this thread with any shortcuts, questions, or comments

Thanks for the hard work you have done deathrow1993 ,I have been around in circles with this, It looks like you have come up with the answer. I have 2 questions for you.. 1: I have CDMAWS 3.9 a little different from the one you have..You mention go to the other tab and under R-UIM Config make sure you select NV only. In CDMAWS 3.9 the R-UIM config is on the main tap and there is also the button that gives the option of CDMA or CDMA2 or EDVO etc. and another button that gives the option of NAM1 and NAM2 .. Do I write to NAM1 and NAM2 under CDMA and CDMA2 and EDVO?? The last question 2: on the program page of DFS CDMA you have 765 2385692 in several fields is this the phone # thanks for all your work with this. I have had the 1X working for a bit now but getting tired of the slow speeds. Again thanks to you everybody else that has contributed to this... Merry XMAS

Thats my cell phone number. Forgot to edit the pictures i guess. If you have cdmaws 3.9 and its the paid version in order to get 3g go to the evdo tab and put yourphone#@vzw3g.com for all fields and vzw as the password. Then have pageplus do a esn reset and a data reset and 3g should work. If its not the paid version then the evdo tab wont write. It sounds like you already have talk and text working? also make sure if you write something (nv only, nam settings, m.ip, and ppp settings, anything) make sure you write to both nam1 and nam2.

Thanks a bunch for your tutorial. I am going to try to flash my spare tbolt to PPC and have been reading everything that I could find.

no problem. just make sure youre on the stock rom so you can get diagnostic mode working. after everything is flashed i know its safe to flash a custom rom and even a new radio. i was on a bamf rom after 3g started working i then upgraded my radio from .9 to .19 and everything stuck. if you have any questions just keep me posted

Deathrow you can still get into diag mode with ICS roms and probably other non sense ones as well. Google "GScript Lite" and you can put your phone in diag mode without the reboot. I am with PPC too and love sense roms for ease of programming your phone without ever hooking it up to a computer but have run into losing data when flashing roms.

Thanks again for your tips. I currently have voice and SMS working...Still trying to get data tho...

deathrow1993 if you ever make it near PDX I'm buying you a beer!
Process worked (took me awhile to find all the tools).
I haven't got a non-vzw-LTE SIM card yet so I have the Verizon one in there (wife's phone...keeps the phone from complaining) and it at least functions with text/voice for her.
I suspect it will start snagging 3G once I get the random SIM card in there.
Best part was that this avoided having to use the paid version of CDMA Workshop (their DEMO version you can download lets you mod only the CDMA pages, not the EVDO). I really didn't want to part with $99 just to program a used phone that isn't even mine
Thanks again! Learned a lot!

HTC Thunderbolt on Page Plus/w Voice/Text/MMS/Web
..Finally, after a week of trying to get data to work, IT WORKS!! HTC Thunderbolt on Page Plus 55$plan, Voice/Text/MMS/Web at 1xCDMA. I started with the tips from this thread and others alike, used cdmaws2.7, DFS4103, QPST366, and WirelessWorkshop dotcom. To be honest, it was the WirelessWorkshop remote software and the Technical help from them(Dwane was his name) that got this working. I could never get the com ports/diag driver's installed correctly. I thought they were but they weren't and WirelessWorkshop(Dwane the tech dude) connected to my pc through teamviewer and fixed my problem with the ports and drivers! Way more than I expected him to do since I only paid to use the software remotely. Before he fixed my pc I could only write to the htc diagnostic modem, not the 9K..So CHeers to him and the rest of y'all that have helped out...
Now I need to get 3G working. I did run across this from another site's thread but I don't know if it works to fix 3G cause there are no other references to it:

I am not sure if changing the "vzw" pass to one of these would work or not.. Has anyone else seen this and does it work to connect 3G?

Hmm...
I popped in a non-4G-LTE SIM card yet still no 1x or 3G data (no MMS or anything).
Any words of insight here?

After having everything working(voice,sms,mms,data1x) for almost a week, I tried to get 3G to work and now I have no data or mms at all...I have tried to re-flash and re-flash, gone over all the settings a thousand times, but nothing...
Brandon314159, wish I could offer some advice but I find myself also asking for help now... The last three times I called PPC and had them reset my data, I still haven't gotten it back yet..

I'm thinking the APN may be wrong on my Thunderbolt (still verizon?) because it wasn't a setting I had to change in this process?
I will have some more time here soon to look at it and see if I can figure it out..

I don't think the sim card really matters much but I'm using the verizon sim because it holds the PRL. 3G data is working for me, you need to be able to write your specific keys to the phone using DFS. This took me a while to figure out but eventually I got my hands on a droid incredible and was able to use it for my source to setup the thunderbolt. I am not sure if there is any other way to work around this or not but it worked for me.
Edit: It may be that you need to do all the programming as stated by the OP before you do the activation or have an ESN reset thru PPC.

EDIT: I was wrong about the sim card but if you have a new one that was NEVER programmed before, then it will work with the 4G LTE sim card.
I had 2 used & 1 new sim card but I could only get the NEW one to work correctly with 3G. Sorry if I lead anyone in the wrong direction.

I am only finding one port (9k) since I upgraded to ICS. Does anyone have a similar issue or could this be another problem?

I have found This rom here to be the most useful in setting things up to where you can reboot to diag mode and then set everything else up as stated in the OP. Once you are finished, flash the rom of your choice but don't go thru with the vzw activation process so all of your settings will stick. They may still stick, I don't know for certain as I have never allowed it to finish.

Coverage extend feature

In Dev settings there is this thing called wifi coverage extend feature, wth is that? I feel like it would make my phone work as a wifi extender for poor networks, but I have no idea if this is what it is or if it even works, could someone please enlighten me? Google, surprisingly, has no answer for this...which makes me more intrigued to find out.

I don't have that in my Dev Settings

Wierd... Had it on 5.1.11 where I first discovered it, and on the betas, and also some custom ROMs, not all of the 4-5 I've tried

In developer settings of 9.0. looks like it's hotspot related.

This thread is the first relevant result when googling for this function.
Might it be OnePlus exclusive?
Does it even work?

I too have it, and was wondering the same thing. Definitely since I can't get VPN hotspot app to work properly using this phone.

I don't know! IDK the intended feature(plug n play maybe, just flip the switch n go?) so how would i try it out?... Ive tried to use it as an extender once, a vague try that didn't result in it working or not working... The other phone just had an acceptable and jumpy wifi altogether so it was a weak try so to speak
Would be cool to know

I was going through this option and I think I found out how to use it. Although my test has been unsuccessful I believe someone can tell me if I did wrong somewhere. So what I found out and what i did basically is
1. Obvious step - turn on that setting in Dev options.
2. Now connect to any WiFi hotspot. After successful connection go to the options of that particular WiFi - like where you see the connection details.
3. Click on the modify network option on top right corner.
4. Expand the "Advanced settings" drop-down option in that submenu.
5. You will now see a checkbox that says "Extend WiFi coverage"
As per my understanding I checked it and then tried to connect my other phone to that same hotspot but from a farther range to the router but within the range of my OnePlus device as if it's acting as an extender. My test was unsuccessful here as the signal was still weak assuming my other phone was still getting the actual signal from the router and not the OnePlus device.
I'd be grateful if someone here corrects me if I did something wrong/missing something and let me know if anyone gets it to work.
Thanks. Cheers!

On your first phone find our the BSSID of your original WiFi network. After you do that find out on your second phone whether you've connected to the original BSSID or your 1st phone's BSSID

I too want to figure out how to get this option working. Can't get it to work..

You need one more step , 6. Turn on your hotspot first than turn on wifi and connect to that wifi in which you ticked extend coverage option and your wifi,hotspot start working simonteneously (remember ssid shown in other devices will be router ssid)
7. If hotspot get turn off after connecting to desire network than try again step 6

How to change APN and update firmware on Samsung SCH-LC11 hotspot

I am debating whether or not to post this here, on Howard Forums or on CDMA Gurus, but I'll post it here as this forum seems the most popular and has a great SEO so hopefully someone googling how to do this will see this thread and find it helpful.
This summer I picked up a used Verizon Samsung SCH-LC11 hotspot. It is surprisingly small and lightweight but heavy and feels high quality.
I was surprised to see the built in web interface didn't have a software update button, nor any options to change APN settings and so on. I searched Google and couldn't find ANYTHING initially on how to do this, but found that there was a software update which mine didn't have that gave it the ability to choose LTE only, 3G CDMA only, and so on, which I thought would be nice to have. After a lot of digging, I finally found out how to do this.
First you'll need to install the latest Samsung USB drivers from here https://developer.samsung.com/mobile/android-usb-driver.html
Once that is done, you'll need to download the Samsung firmware update utility for this hotspot which can be found here
Verizon: https://www.samsung.com/us/support/downloads/?model=N0020110&modelCode=SCH-LC11ZKAVZW
US Cellular: https://www.samsung.com/us/support/downloads/?model=N0020124&modelCode=SCH-LC11ZKAUSC
Download the one listed as "PATCH,OTHERS" and run it, and follow the instructions, once that's done you should now be on the latest firmware!
This next one is something that initially was reported as impossible, changing the APN settings. There is nowhere in the web menu to do this and when you plug this device into your computer nothing happens.
After months of searching though, I finally found a thread on CDMA Gurus related to flashing and doing more involved things with this hotspot, and this showed how to enable debugging mode!
To do so you'll need to power your hotspot on and connect to it's wifi network, and then head to the admin page at http://192.168.1.1/ and login with the wifi password found on the sticker underneath the battery cover. If your sticker is missing the password is the last 8 digits of your IMEI, ignoring the last digit of the IMEI. For example if your IMEI is 123456789123456 your password is 78912345.
Once you're logged into the admin page go to http://192.168.1.1/selectusbmode.html and enable USB debug mode and click Save. Then go into "Configuration" and "Diagnostics" and click restart and connect the hotspot to your computer via USB. You should hear the device connect sound.
Now you'll need to use a program called AT Command Tester available at https://m2msupport.net/m2msupport/download-at-command-tester/ as we will set the new APN of your choice using AT commands, and this program let's you do that all through a simple, easy to use GUI.
You will need the latest version of Java installed on your computer as AT Command Tester requires Java to run, you can obtain the latest Java here https://www.java.com/download/ie_manual.jsp
Once you have the latest version of Java installed and have downloaded and installed AT Command Tester, open up your start menu and launch AT Command Tester, if this doesn't work navigate to C:\Program Files (x86)\AT Command Tester and run "atc.bat"
You should see AT Command Tester open, and now you'll need to establish a connection to the Samsung hotspot. Click on "Find Ports" and wait, now you should see 3 COM ports available from the dropdown selection list, in my case it was COM16, COM17 and COM18 and the one I needed to use was COM16, however yours may vary and you may need to try each one until you establish a connection, I'd recommend trying the lowest numbered one in the list. Once you have selected the proper COM port click "Connect" and in the log in the right you should see it detect the hotspot and list Qualcomm as the device type.
Now you can follow the instructions here for setting up the APN https://m2msupport.net/m2msupport/how-to-setup-access-point-network-apn-in-cellular-modules/ and once you have set the proper APN you can restart your hotspot and you should have everything working!
If you for some reason need to change other settings, you can use DFS Qualcomm Tool to do so. This device will also be detectable via QPST and CDMA Workshop too.
