OK, this took a lot of trial and error, some bravery on my part, and SEVERAL calls to AT&T, but I finally got it working!* I am not a Dev anywhere CLOSE to the likes of DG, but I do have extensive knowledge of hacking mobile devices in general, GSM networks, CS/PS infrastructure, and industry experience from the NOC side of several MSOs (aka ISPs), so I tackled this problem from a "what would I implement if I were AT&T and wanted to force a tethering package on subscribers?" Point of view, and worked backwards from there.
Many have tried the solution already posted, and I give credit to the poster of that original "fix" while respectfully pointing out that using this "fix" accomplished AT&T deleting my data package twice, and provisioning a tethering plan automatically once, all automatically done by the system. This was not the solution I was looking for.
So, without further introductions/banter on my part, here is the step-by-step... I will try to keep explanations to a minimum for now, if they are asked for I will put them in post #2.
*Prerequisites: ROOT
*Tools required: Root Explorer, SQLite Editor (both available in market, yes they are paid apps but they are WORTH EVERY PENNY!)
----note: this can also be accomplished using adb and a sqlite database editor on your pc, but requires many, many more steps, and won't work after reboot unless you have a working busybox and can successfully chown/chmod the .db file after you copy it back to the device, and even then I still had trouble with it after reboot, so... I had success with these paid apps, so I'm writing the tutorial assuming you have them. If there is enough demand I'll write an alternate tutorial on how to do this using free tools.
*******
++++++++++++ Edited, now shorter! Thanks to all for testing these settings, the new steps are confirmed working!
*(if you used the steps prior to my editing them, you're good, your settings will work fine, the changes reflect a different, shorter way to do this)
1) Create a NEW access point setting using the following settings: (SETTINGS>WIRELESS AND NETWORKS>MOBILE NETWORKS>ACCESS POINT NAMES> {press menu} NEW APN
Name: whatever you like here, I use att
APN: wap.cingular
Proxy:
Port:
Username:
Password:
Server:
MMSC: http://mmsc.cingular.com
MMS Proxy: wireless.cingular.com
MMS Port: 80
MCC: 310
MNC: 410
Authentication Type:
APN Type: default,agps,fota,supl,fota,tether,mms
(all settings I left blank, leave blank, make sure you press menu, save to save)</br>
2) Enable Airplane Mode
(hold power button for three seconds, select Airplane Mode)
3) Open Root Explorer
4) Navigate to: /data/data/com.android.providers.telephony/databases/
5) Click on "telephony.db"** (this should open the db using SQLite Editor)
6) Select "carriers"
7) You should see a long list of APN settings for various carriers, the ones you are interested in are rows 4, 6, and 7. Scroll ALL THE WAY TO THE RIGHT and the last column should be labeled "preloaded." You will notice that each is labeled "true" press and hold the word "true" in row 4 and select "Edit Field" from the pop up menu. Change the "true" to "false" and click "Save". Repeat this step for rows 6 and 7.
7b) Edit the type field of row 6. Right now the field says "tether". Change it so that it says "default,agps,fota,supl,fota,tether"
7c) Change the APN field in row 6 from BROADBAND to wap.cingular
8) Press back twice to close the SQLite editor and you should be back in Root Explorer. Close Root Explorer.
9) Disable Airplane Mode
10) Go back to the list of APNs you saw in step 1. You should see that the "locked padlock" is now unlocked on the preloaded APNs named AT&T US, AT&T US HSDPA, and AT&T TETHER. You now need to edit the one labeled AT&T TETHER. Change the following settings:
APN: wap.cingular
Proxy:
Proxy port:
APN type:
Press menu, save.
11) Select the radio button for the APN you created in step one. AT&T Tether.
12) Reboot phone.
13) Enjoy! Mobile Hotspot should now work first time no issues!
Note: (Due to some pre-existing (bug?) in the software, you do need to have wifi turned on BEFORE you enable Mobile Hotspot for it to set up properly. If you forget it will hang until you enable wifi.)

After staying up all night to figure this out, I have confirmed that using the Webtop without dock MOD combined with mine you CAN use webtop with your 3G/H+ connection!!! No wifi required!
Steps to make this work:
1) Connect Webtop
2) Using the window that allows you to control the regular phone interface, navigate to the ACCESS POINT NAMES menu described in step 1 above.
3) Select the radio button next to "AT&T Tethering"
Done! Open firefox and enjoy!
Credits to Fenny, author of the MOD to enable Webtop without dock!
Also designgears, author of Adeo, which is necessary to run aforesaid MOD!
And to t0dbld, who contributed significantly and led the discussion that resulted in said MOD.

It should, though I personally own neither, and therefore have not tested that particular functionality. There is no way that I am aware of that AT&T SHOULD be able to tell any difference between traffic from tethered devices and traffic from the device itself, so unless they are packet sniffing (illegal for ISPs, somewhat hazy regulation on wireless service providers, but would be a BIG shock to me if they were) or there is something in the actual webtop ubuntu software that would inform AT&T that webtop is being used somehow (also HIGHLY unlikely, as it would be a HUGE invasion of privacy) the answer is YES!
PLEASE if you have access to either of these $$$$$ expensive docks if you wouldn't mind test this for me and report back to confirm that indeed it does allow use without wifi.

Thanks!
or even better, attach the original sq file?
I hate that you are probably on final steps, but... You cannot re-create the AT&T Tethering profile manually, as this will break the functionality of the script that Mobile hotspot uses to "Verify" that you have a tethering plan...
Please go to your APN list, and press MENU>Restore Default Settings
Then (sorry) start over from step 1

I can confirm that this works great - you no longer get stuck at "setting up data link" (so no more changing APNs to fix that).
Although, I tried the newly found webtop hack which allows you to just connect the HDMI cable to a TV and run webtop - it does not work without wifi. If you try turning off wifi and use 3g, it says "communicating with ATT to see if webtop something something" and nothing loads.

Good work richhed!
Wifi hotspot works, but it does not seem to work with the hd dock over 3g only with wifi. There must be another check somewhere along the way. Too bad, hopefully we canfigure it out soon though.
I'm using the Atrix in Australia on the 3/Vodafone network, is there a way I can get it to work?

great find on unlocking there crap !! btw if you delete the apn type or the apn all together for the tethering etc you wont have to do the wifi on off thing, you have to do that because sometimes its still defaulting to the apn that is strictly tethering

Yes it does , i would check your settings again , jsut because the blue tethering active comes up does not mean it is tethering an active connection, recheck your settings and try again, working fine here

I for one would be interested in a tutorial with the alternative method!
Nice job! This hack is based on the same principle as the TBH NVRAM tether hack that we released for Droid devices except yours is done by changing the APN in the system and ours is done by changing the Tethered NAI(Network Access Identifier) strings in the NVM because that is where the carrier data authentication components are actually stored in CDMA phones. With GSM all of that is stored in the SIM card itself and is not accessible in the NVM.
The change does functionally the same thing, that being making all data use appear to the network as internal data rather than flagged as an externally tethered device.
Congratulations!
uhm I tried this, when i launch with internal viewer, i cannot edit. but when i try to launch with the db editor, it wont open cuz it says no network connect (since we turned on airplane mode)
EDIT: nvm I needed to download the editor from the market since I didnt have one installed.
Can we delete all of the other APN settings without ill-effect?

Click to expand...
Click to collapse
ikenley,
I am less familiar with your network, and I'll also need more information:
1) Are you using a US, AT&T branded Atrix?
2) What are the DEFAULT, working APN(s) for 3/Vodafone "smartphone" data plans?
3) Do these APN(s) require login credentials, and
4) Do they proxy their smartphone data plan
Unfortunately, if the answer to #4 is yes, then the answer is no, it (probably) won't work. Also, if they require a login, it depends on the type.

LOL, I was hoping that you wouldn't say that
Every time I personally tried I couldn't get it to stick on reboot, I think I may have been doing something wrong with the chown or something. Give me a few days I'll keep at it ;-)
BTW, if you have a basic knowledge of adb, and bash or busybox or any linux based command line terminal, basically you follow all steps the same except when you are editing the .db you'll need to copy that file to the sdcard, then to your pc, then edit it, then copy it back to sdcard, then back to /data/data/com.android.provider.telephony/databases/ and THEN you have to use adb shell to chown/chmod the file to the proper settings. I think it may be that the group ownership is changed to sdcard when you move the file... Anyway I'll work on it.

After calling customer help for hours and getting useless tips, I thought why not post it here.
I have a P1000L Tab, and the internet for the tab seems to go through a proxy, which was setup in the APN section in the settings menu. However, only the Browser seems to work well. Every single other app, including market, just tries, but fails.
I downloaded the Dolphin HD browser, but only viewing pages work, dowloading gives me a "no connection" error, while using flash just crashes my browser. Again, these things work on the regular browser.
So, is there any way I can fix this? I'll go as far as rooting and installing some custom ROMs if I have to, but that's on my to-do list anyways.
TL;DR, Internet wont work on anything except stock browser. I suspect the APN setting are to blame. Any help is appreciated.
You didn't mention your country or carrier, but go to google, and search "my carrier my country apn settings" and you will get what you need.
You shouldn't be using a proxy.
I've seen a few different solutions to the spotty MMS issues on custom 4.2.2 ROMs floating around so I thought I would create a thread to catalog them here. For those wondering there is an issue with seemingly all the D4 4.2.2 custom ROMs that causes MMS to randomly stop working. It seems rebooting or wiping cache/dalvik seems to fix it for some but it eventually comes back. I don't send many MMS messages so I can't really attest to how well any of these work.
Solution #1:
1. You will need a root file explorer like Root Explorer.
2. Navigate to /data/data/com.android.providers.telephony/databases/telephony.db
3. Rename telephony.db to telephony.db.xx
4. Reboot your phone and all should be well.
(Thanks to NeoPheonixTE on DroidForums for this one)
Solution #2:
Use the Verizon Messages app from the Play Store.
(Thanks to ws6formula350 on DroidForums for this one)
Solution #3:
Go to Settings, Wireless & Networks, More..., Mobile Networks, Access Point Names. Scroll down until you find whichever APN that your phone is using - in my case, my phone uses "LTE - Verizon Internet". Tap on the selection - NOT the blue bubble on the right - and scroll down until you find "MMSC". Tap on that, and in the box that comes up, type "http://mms.vtext.com/servlets/mms", without the quotes. Submit, press the Menu key, tap "save", back out to the Home screen, and reset.
(Thanks to Jishkah on DroidForums for this one)
If others have suggested these solutions elsewhere let me know and I will give them credit as well.
Good luck and let us all know if any of these solutions work for you!
Hey. Made an account to say this: I'm not sure if Solution #3 works. More than anything, I've found that MMS in custom ROMs are a hit-or-miss; every once in a while, they'll send, but, a vast majority of time, they won't. I found that bit of advice - changing the MMSC setting - on another website, and it seemed to work for me. However, the Droid 4 jumps between EHRPD - Verizon Internet, and LTE - Verizon Internet, so I'd recommend applying this setting to both of those networks.
Once again, I'm not sure if that'll work for sure, but it's worth a shot, no? Another idea that I had would be to copy the APN settings from the stock ROM to whatever custom ROM that you're using - I haven't tested this out, but it may work. It may also bar you from using Wireless Tether, too. Once again, I'm not an expert.
This mod will enable native hotspot to work w/ 4G
You will need a root file explorer and sqlite editor to complete this mod.
Your choice to flash this- Do a back up
After that- GET S-OFF
Sunshine will cost you, but is well worth it.
Instructions:
1) Flash the attached aroma installer in recovery.
2) Select the appropriate option, click install, and reboot. Upon reboot your phone will optimize
3) Once rebooted, navigate to /data/data/com.android.providers.telephony/databases with a root explorer
4) Open the cdmaapn.db with a sqlite editor and select carriers.
5) Scroll over until you see the block of apns with a 1 in the current column
6) In that block you want to edit the apn labeled Internet. Open it and delete hidden. Just leave it blank, and hit save.
7) Go to settings>mobile data. You will see a new option named Access point names. Tap that, and then tap the apn
8) In the Apn type section add ,dun. IMPORTANT- no spaces. So you would end up w/ default,mms,supl,hipri,dun w/ no space after.
9) Tap the Apn protocol and change it to IPv4.
10) Reboot. After booting back up, tether should be good to go
Notes:
1) The flash will install a script that disables IPv6 for wlan0. If you need that don't flash this
2) It is a good idea to forget any wifi networks that you regularly connect to, and reconnect
3) When you are not tethering you can switch the APN protocol back to IPv4/IPv6 if you choose, though I have found no benefit to doing so
Credits:
@OMJ- He put the aroma installer together. It would be a lot more complicated to get this on your phone without it. I have been working on this for a good while, but didn't have 4G in my area until last week. Without he and @benny3 testing, this would have been a while longer coming out.
I have tested this on the following Bad Boyz roms- Stock Rooted, L w/ Sense 6, and L w/ Sense 7
EDIT: Please do a profile update after doing this.
EDIT2 New option added for Non- Bad Boyz sense 7 ROM's HERE
huge kudos to @chas123 for figuring this out!

This is amazing work and a huge step forward.
I have a question for you though.
Is there a way to cut out any of these steps by flashing a modified file to the corresponding location?
My idea is to write a modified cdmaapn.db to /data/data/com.android.providers.telephony/databases
and possibly even a modified APN config.xml.
Would it be the same across roms?
I know most would frown on this because if you want the goods you should be able to make a few edits and reboot, but if it can all be done by flashing something in recovery or through the same aroma, it could save time and cut out user errors.

It was tried. Flashing a modified database causes the phone to fc, and revert back to the old apns. Sprint doesn't use the apn config file. It uses a .dat file in /system/customize

Here is a log. Log should begin when I use the tether in the quick settings. I connect my windows surface pro 2. Everything connects and I am able to successfully browse for a couple minutes then the data connection on my phone will disconnect then reconnect several seconds later. I have to reset the tether connection to get back online. Does this on 3g and 4g. I have flashed the aroma file and made the edits as necessary. Think this is related to this being a windows device which would be red flag to tethering without a plan? If this device was pinging a MS server for an update it would be very obvious. On the plus side my market WiFi tether app works good, however having the native app to work would be great. Many thanks for your contributions.

Hey everyone I'm rooted and everything so I've been trying to find a way to get around paying $30 for a hot spot that should come with the phone. anyways I found a way to disable the "you are not subscribed to hot spot" thing but when I connect anything to the hot spot I keep getting errors saying the DNS couldn't resolve server names. I tried for hours with different DNS servers so I'm guessing it's something vm has done. If anyone could help me with this I would greatly appreciate it I used it a lot before I got this phone and now I'm kinda stuck :/
I know from experience that you can usb tether with pdanet and it'll hide your tethering with metro. It will not however hide hotspot HOW EVER you can use its experimental feature internet sharing which is essence creates a hotspot however I've only ever been able to connect to a phone that was with metro AND the phone that was hotspotting was not with metro. Trying to do so with my metro phone give me dns errors as well.
I haven't tried to use USB tethering yet only because some of my things can't be tethered via USB. I just don't see why I'd be getting DNS errors now and never did before. Oh wel. Surely someone here will have a solution for me soon.

Are you sure? I tried this app before and it wouldn't broadcast the network. And yes I am rooted. I found a way to partially get the native hotspot working but it's a pain in the butt. If I could figure out how to edit the apn settings I'd have it going in 5 seconds but they're locked and htc phones don't have a "hidden menu" like lg phones.
Weird... Well, If you can't get that working, I'll let you know my current configurations for that app.

I'm looking for a solution for the hotspot on my 626 from Verizon.
native mobile hotspot and tether on cricket
I was able to use the phone as a wifi hotspot by doing the following:
1) install the following apps: MK explorer, Axel (xml editor)
2) phone must be rooted
3) using MK explorer navigate to the following folder (root directory): /system/customize/ACC
4) make a copy of the default.xml file and rename it in case it gets corrupted
5) run Axel and open the default.xml file for editing
6) scroll down about 80% from the top of the file to find the entry (find didn't work for me):
<app
name="Tethering_provision">
^ <item
type="integer"
name="TetheringGuard_Rule">
. 3 (note:dot is in middle)
7) edit the entry to change the 3 to 0
8) use "save as" and save modified file
9) rename the edited file to default.xml
10) reboot
11) go to settings->more->mobile hotspot and tethering, click on Mobile Hotspot, click on OK, change the hotspot name and password to what you want
12) after this step the phone just sat there so I rebooted
13) hotspot now works
I have no idea if this is hidden from the carrier
