[MOD] Enabling tethering without paying for apps

Blatantly ripped off from richhed's thread. I'm a cheap [email protected]$#^&* so I wanted to enable wifi hotspot without paying for apps. Here's how.
I'm writing these instructions for Win7 x64, and assuming that your USB drivers and busybox are working. YMMV. No, I won't help you fix your phone if you brick it, and won't be responsible if it doesn't work for you.
1. Download Superoneclick 1.6.5 for rooting your phone. Your phone needs to be rooted, if you haven't done this yet you need to do it now.
2. Download SQLite database browser on your PC and unzip to some folder. Remember where this is.
3. Plug phone into PC and turn airplane mode on.
4. Open a command prompt as administrator (right-click, open as administrator)
5. Navigate in the command prompt to where your Superoneclick is unzipped (for me, it's in a folder on my desktop)
6. Run 'adb shell'
** note** all commands from step 7 to step 12 are in the ADB shell
7. su (if you rooted in step 1, you may have to allow access, watch your phone as it may ask)
8. mv /data/data/com.android.providers.telephony/databases/telephony.db /data/data/com.android.providers.telephony/databases/telephony.old
9. chmod 777 /data/data/com.android.providers.telephony/databases
10. chmod 664 /data/data/com.android.providers.telephony/databases/telephony.old
11. exit
12. exit
13. in the same command window which your second 'exit' command dropped you to, type 'adb pull /data/data/com.android.providers.telephony/databases/telephony.old ./telephony.db'
14. Run SQLite database browser and open the telephony.db file that you downloaded to the Superoneclick folder in the last step.
15. Click 'browse data' and select table 'Carriers'
16. You should see a long list of APN settings for various carriers, the ones you are interested in are rows 4, 6, and 7. Highlight row 4, named 'AT&T US HSDPA'. Scroll ALL THE WAY TO THE RIGHT where the title of the last column says "preloaded." Double-click the field that says 'true', and in the resulting dialog box change the "true" to "false" and click "Apply Changes". Repeat this step for rows 6 and 7.
17. Edit the 'type' (3rd last) field of row 6. Right now the field says 'tether'. Double-click and change it so that it says 'default,agps,fota,supl,tether' and apply changes.
18. Change the 'apn' (6th) field in row 6 from 'broadband' to 'wap.cingular' and apply changes.
19. Click 'save' and exit the DB browser.
20. Back in the command window, type 'adb push ./telephony.db /data/data/com.android.providers.telephony/databases/telephony.new'
21. Run 'adb shell'
** note** all commands from step 22 to step 32 are in the ADB shell
22. su
23. cd /data/data/com.android.providers.telephony/databases
24. su radio
25. cp telephony.new telephony.db
26. chmod 660 telephony.db
27. rm telephony.new
28. exit
29. cd ..
30. chmod 771 databases
31. exit
32. exit
33. Disable airplane mode
34. Go to Settings>Wireless + Networks>Mobile Networks>Access Point Names. Select radio button for AT&T Tether.
35. Reboot phone.
36. Mobile Hotspot will still validate but will turn on when using this APN. You might have to switch APN's after a reboot, I've had to and at least one other user has had to.
If you ever want to revert, we saved the file as /data/data/com.android.providers.telephony/databases/telephony.old in step 10. Just 'su' and 'cp' that puppy overtop of the existing telephony.db, remembering of course to enable airplane mode.

Not trying to start anything, but theres already a pretty good thread on this bro.

stop linking android-wifi-tether.
Infrastructure AP (what this and richhed's method and others enable) > Adhoc (what android-wifi-tether enables)
Google the differences. Ill give you a couple reasons to start
1) a lot of corporate laptops disable adhoc connections
2) Adhoc only allows WEP - crackable in 30 seconds, a huge security risk. Infrastructure allows WPA2...
so if you dont care about any of those, then yes, android-wifi-tether is fine... and much simpler.

Number 2 is kinda a mute point as if your using your phone to tether i doubt its going to be your primary connection. Also the fact that your not even going to see your phone after about a 100ft for tethering it would be pretty easy to narrow down someone hacking into your wep

Number 2 is pretty important; it only takes about a minute to hack through WEP when the connection is in use.

Yea think you missed it completely

Yes. I flashed Motorola Atrix 4G U4_1.5.2 last night, restore my apps with mybackuppro this morning and this was the first thing I tried.
Just loaded it. Didnt have to do jack. Changed SSID, changed encryption. Not letting me change password, wanking the 13 character requirement when I enter a 16 character ASCII password is too short.
But the app worked beautifully. I have tried the other methods, modding db's. That didn't work until I added this below.
Tether without at&t tethering plan: (thanks to Fixter)
http://forum.xda-developers.com/show...&postcount=193

after doing this. mobile hotspot is still greyed out in settings. It says 'high speed coverage required'. granted i am on edge with no way to test 3g atm. I am wondering if this is normal and if there is a way to enable the hotspot over edge? (yes i know it would be impractically slow)

Finally got around to doing this and it worked great.
A few corrections to your steps.
Step 3. Plug phone into PC. (I know stupid explanation, but some people may forget.)
Step 15. Select Table 'Carriers'
Step 34. 34. Go to Settings>Wireless + Networks>Mobile Networks>Access Point Names. Select radio button for AT&T Tether.
Finally, I had a ton of APNs listed in my phone. Something like 80. The ATT ones were listed near the bottom. I am not sure if this is because who I purchased my phone from, Walmart, but maybe you should give some description of rows 4,5, and 6 so that people will not get confused. I figured it out fine, but you never know.
Finally, this works in webtop, but it appears that on every reboot of the phone you have to change the APN setting when you first use webtop. It doesnt seem to matter if you are already in tethering, you have toswitch away and then switch back. After you do this once everything works fine until the next reboot.
Thanks again.

It isn't so much someone could access your wifi tether, but more that the data can be captured and easily decrypted. Anything you do over that connection may as well be broadcast for all to see. (Unless you're using https etc for everything)
I use the android-wifi-tether app on bluetooth only, unfortunately it also sucks battery more than the usb port on my mac can supply so the battery depletes in a few hours.
Thank you to the OP for providing a way to enable the built-in tethering.

Thanks for the step by step

I am not sure if it made any difference to it working, but as I'm with Telstra (Australia) I added 'default,agps,fota,supl,tether' to the entry for "Telstra Internet" and it works perfectly.

Not sure if this has been beaten to death yet, but do we for sure know that AT&T cannot track this? How are connection speeds?
I've read a few posts expressing concerns about AT&T automatically switching people to the tether/4GB plan (I have the 2GB plan), and also slow (<1mbit) download speeds. Can someone shed some light on this?

i think they can tell when we swtich from "phone" to "wap.cingular," it showed a record of me switching between the two. I also looked up my data usage and got 2 reports of usage rather than just one. still my data plan has remained unchanged. this also happened when i would switch out my sim card b/w my windows 7 samsung focus and my dell streak, and att didn't do anything. i figure if they contact me about this i can just say i've been swapping my sim card between phones. don't think they can tell the difference there (may be wrong).

[Q] MY Phone Number

I have been successfully using the Verizon FIOS remote control app to control my TV FIOS STB and it is much nicer to use than the standard IR remote.
To get it to work originally using a nightly (circa 128), I had to persuade the Nook that it had a phone number as this is registered against one set in the STB. I did this by going into Settings/Call Settings/Additional Settings. This gives a network or SIM card error but when OK'd allow me to manually enter a phone number which then worked fine and continued to work through many nightly updates.
Something has now changed (I am currently on nightly 200) as I find that I have to re-register the FIOS app almost daily to get it to work.
On checking I find that the Phone Number setting gets lost periodically and set back to Unknown and I have to manually enter it again.
Does anybody know whether CM7 behaviour has changed with respect to the storage of the Phone Number? I realise it would normally be on a SIM, but it does seem to stick around for quite a while on the Nook before getting lost.

Any luck with this? I've been trying to figure out a way to do this for a while. I am unable to set a number as you described as all settings are greyed out. I'm also on nightly 200+. Seems like there would be a system file we could edit to fake the number, or something like that. Was thinking about setting up a SIP account to try it, but I doubt that will work.

I have made some progress investigating this but have not got a final solution yet.
First, I can set my phone number up even though it is not a phone. I go into Settings, Call Settings, Additional Settings. The screen blurs and brings up a dialog box saying Call settings Error - Network or SIM card error. If I OK that then I see 3 menu items. The first 2 are grayed out but the 3rd "My Phone Number" is enabled. I select that and can enter a Phone Number. Are you saying you get the error and then all 3 options are grayed out?
Once entered I can view the Phone number via Settings, About Tablet, Status.
So far so good. The phone number setting does not normally survive a reboot, and also typically reverts to Unknown after a couple of days even without a reboot.
I have traced the Phone number setting to be stored in com.android.phone_preferences.xml which is in /data/data/com.android.phone/shared_prefs
But when the Phone number disappears it doesn't disappear from this file so there is some more complex interaction with trying to read a non-existent SIM first. So far I have traced the code involved to MyPhoneNumber.java and MSISDNEditPreference.java which are in the CyanogenMod-android_packages_apps_Phone-5d2764c.
I am still working on understanding this to see if there is some work-around to make the setting stick better. Currently I just have to check the phone number manually and set it again when it disappears.

Hmmm. When I go into call settings, all settings are greyed out except for internet call settings at the very bottom. I see the additional settings field you are speaking of but as its greyed out nothing happens if I click it. Weird.

Yes. That is strange. All my settings in Call Settings are enabled even though most are inapplicable. I don't think I have done anything to explicitly enable them and I'm on a standard Nightly 240 with the updated SystemUI.apk which turns off the phone signal bars. But I've never had these greyed out with any nightly build before.
Anybody else comment on whether their whole Call settings are enabled / disabled?
There is also a setting in build.properties in the system folder with a key called
keyguard.no_require_sim
I think this may have effect on how the OS treats calls which access the SIM. On my system this is currently set to 1. I might try playing with other values like true, 0 to see what effect that has.

Another theory as to why your call settings may be greyed out is that it they may get disabled in airplane mode.
Now this could be an issue even if you have set and subsequently cleared airplane mode as I believe the airplane mode setting doesn't go away entirely and can cause problems.
There is a command line way of clearing this setting completely which I did once when I set airplane mode on. Search for something like airplane sqlite to find the instructions.

That was it. I was stuck in airplane mode, and must have been for a long time. I used Android Assistant to clear the setting and it worked. I'm able to set my number and use fios mobile remote now! Thanks for your help.
Where did you get that updated systemui.apk to clear the cell signal bars? Now that I got the airplane mode off I have the signal strength there for no reason.

I got the SystemUI.apk from here
http://forum.xda-developers.com/show...60542&page=547
I just replaced the one in system/app. If you overwrite then you might get status bar forced close but a system reboot will sort that out and I haven't had signal bars since.
I've now put this in a zip that I can use to install after any nightly update I do as I've now found there is a wifi patch to deal with any remaining SOD issues although I haven't had one of those for a long time now.
Hopefully this stuff will get put into the main build before too long.

Looks like your link got clipped. Getting a page not found error.
Also, do you have any instructions on how to put the .apk into a zip for re-install after you do an upgrade? I'm assuming its not as easy as just ziping the file up?

Updated link
http://forum.xda-developers.com/showthread.php?t=960542&page=547
Yes. It is as easy as zipping the file up, but you have to create a matching folder structure to determine where the file goes. So in the case of the SystemUI file you create a folder called system containing a folder called app, put the file in the app folder and zip it so that system is in the root of the zip.
Correction: I thought that zip method was working but it wasn't. I had manually put the files in anyway and that worked OK. Then I was testing the zip, but it was actually failing.You need to put the files in a zip with the meta-inf etc. I think this link gives instructions
http://alldroid.org/default.aspx?g=posts&t=855
No. That doesn't work either as it uses an older method of scripting no longer supported. Apparently it needs to use Edify scripting now. It looks like some people add files to the gapps package, but I'm not clear yet whether it has to be re-signed, and I don't particularly want to redo gapps just to do this minimal patch.

I think I now understand how to produce an update zip that works.
I first took a gapp zip and stripped out all the existing files under system leaving the meta-inf alone. I put in the patch files in the appropriate folders under system. I then modified the updater-script in the meta-inf tree to just mount system, run package_extract_dir("system", "/system"); and unmount system with changes to the ui_print
I then signed the zip using the win-sign utility available here
http://forum.xda-developers.com/showthread.php?t=629151&highlight=sign+zip+files
I tried this out by first updating to nightly 246 and then applying my patch containing the SystemUI and the wifi driver that fixes SOD and that seemed to work OK.

[MOD] Native Hotspot- Working 4G

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!
Chas put a lot of time into this, make sure you thank him!!!

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

None of this is necessary with a tethering plan. If you want to post up a logcat of when the data disconnects I'll look at it.

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.

[TIPP] Remove S Finder and Quick Connect from Menu

hi guys,
many of you will find the space taken by the "quick connect" and "s finder" buttons in the pulldown menu wasted.
since i already read requests on how to remove them, here is the simple way:
caution: you need to be rooted
grab a file explorer like "root explorer" and navigate to /system
create a backup of your build.prop-file
now edit the build.prop and change the line "ro.product.name=trltexx" to "ro.product.name=trltevzw". save the file and reboot your phone.
your phone will now think it is the verizon variant and hence show a different 4g-logo, but apart from that your quick menu is clean and you don't have that menu space wasted anymore.
as always, i am not responsible for whatever harm you do to your phone.
btw: you could also change the value to "trlteatt", but that will change further stuff (like boot animation) so rather go for the verizon variant.

There's also a positive side to it: When using the phone with one hand you can reach the notifications much easier.

Thanks. I changed mine from tre3gxx to tre3gvzw on my 910H and that annoying row is gone.
Oops: It didn't connect to network. So back to tre3gxx.

Is this the exynos version?
In this case you need to either write the whole string to what I have or check what other values are legit for exynos phones.

Yes it is exynos version. trltevzw didn't work too. That bar was gone but it didn't connect to network. Btw there is here is no LTE in my region.

there is no reason that this only works for the snapdragon version.
if you have a exynos version you need to find the product code of a exynos note 4 variant and provider who disables it by default and choose that.
what you basically do by changing it to treLTEVZW is tell the software that this is the verizon variant and the software will disable those menu features because that was a deal struck between samsung and verizon. so if you find a provider that has those features disabled on an exynos version you just need the product name and use it.

i tried this on my exynos version and upon reboot, i lost my IMEI, it was showed as null/null..luckily i had EFS bacup, tried restoring that but then my phone went crazy, restarting every 20 seconds, restored the original build.prop aswell, reflashing the FW from odin fixed it! Phew

Are you sure you did nothing else? The build.prop has nothing to do with your imei.
What you describe is usually result of bad modding or flashing.

The OP actually works. Make sure the permissions are rw-r-r.

Thank you for the author. Good work.
Edit:
Unfortunately the feature to increase/decrease the brightness in "auto" mode disappeared. I need this function, therefore I had to revert back.

[MODULE v17.x] VoLTE & VoWiFi Enabler (2018-09-20)

Update: This module was a trial. The results seem to indicate that there is significantly more work to do to enable VoWiFi or VoLTE.
I will leave this module up for anyone interested in enabling the options, but please be aware it will not make these features work.
VoEnabler
This module edits build.prop to enable VoLTE & VoWiFi features on your device.
Download via Magisk Manager or from GitHub.
Important:
This module will not add VoLTE/VoWiFi support to a device that doesn't already support it.
The module will not add VoLTE/VoWiFi support to a carrier that doesn't already support it.
Notes: 2017/08/01
I've changed the module from VoLTE Enabler to VoEnabler and added VoWiFi options. I was going to split them into different modules, but I don't think there's really a point. If you want one you probably want the other and if your device doesn't know what the options are then it should ignore them anyway.
Suggestions: I'd remove the "VoLTE Enabler" module before installing this because the options are the same, but even if you didn't, it won't cause problems.
What did I change?
Code:
# Debug Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
# Radio Options
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
Why?
My carrier supports VoLTE/VoWiFi but not on my device. I made this module to forcefully enable it to test if it worked (it hasn't so far).
The only reason I've published this is to give others the chance to try. It may very well do nothing at all. If no one reports success, then I'll update the topic and ask the mods to lock it.
As I understand it, VoLTE and VoWiFi both require carrier side support anyway. Next step would be to see if it's possible to get the settings from compatible devices and see if it's still possible to make a module.
If anyone has any to add or suggestions for doing this, please let me know.
I'm not going to be providing any support for this because I'm not convinced it even works, but your mileage may vary. *shrug*

2017-08-16: Updated post to reflect that this module will enable the options, but won't make them work. Leaving module up for anyone who wishes to experiment.
2017-08-02 (v1.1): Removed "persist.data.iwlan.enable=true" as this was reported to break WiFi calling on some carriers.
2017-08-01 (v1): Renamed to VoEnabler and added VoWiFi options. Replaced attachment.
2017-07-31 (Beta): Initial commit.

It is not like that. It supposed to be your are on LTE, and then when you trying to make a phone call, it will immediately switch to HSPDA/3G, and get back to LTE as soon as the call ends. That is the symptom that VoLTE is not supported by the carrier. So if it is working, it should remain on LTE whenever you making a phone call.

What advantage does the flame make and is it maintained in LTE?

If it's working, you'll see a little VoLTE icon in the status bar like either of these...
Edit: Sorry. Just to clarify, if the module is working you'll see something like this... in "SIM & Network" in settings.

The advantage is higher quality voice when on phone calls. That's really about it.
VoWiFi also exists which lets you make and receive calls from WiFi in case you don't have signal.

Not only higher voice quality but faster dialing too. [emoji6]

Thanks

On my phone i changed the CSC-File to enable VoLTE and VoWiFi, i didn't know that it can be enabled in the build.prop too. i have a S7 Edge BTW.

From memory, that's a Samsung only feature? CSC files.
The build.prop stuff is generic so should work on any device. And Magisk so means not modifying /system.
I'm still not convinced it does anything by itself, but I figure it's easier to make a simple module and let folks give it a try. If it genuinely does nothing and no one can figure anything else out, then I'll delete the attachment and modify the first post so at least there is something to search for that says "THIS DOESN'T WORK. DON'T BOTHER".

Just tried this on my OP3, gave me the enhanced 4g option but when I turn it on it doesnt make any difference. On call the network drops down to 3g/H from 4g LTE

Yes in the CSC-File you can enable and disable, some hidden features specifically for Samsung Phones. I also made an Magisk Module to activate some features systemlessly like App-Lock, Floating Messages, VoLTE, VoWiFi and other but I will test out your Module and look if it works with my phone.

Just tried this on my OnePlus 3 that is on ATT and it did not work. I did enable it in settings as well before trying. If we could get this to work that would be great!

I have a Huawei P9 lite and I installed this module. New options have appeared in the settings but unfortunately despite my provider supporting VoLTE when I call it always goes to 3G

doesnt work with BQ Aquaris X5 Plus (Gohan)

With the 1.1 update I'm getting VoWiFi and it seems to work. VoLTE remains elusive.

I don't think it's that easy.
I asked the developer of the ROM I'm currently using for activating VoLTE.
He said maybe in the future, because a lot of modifications have to be made, not just editing build.prop.

Magyar Telekom also introduced the VOLTE service. I asked why it did not work on my OP3 phone. I got the answer that it would only work on Samsung phones on their network.
No comment...

How to edit the VoWiFi settings to put my carriers server to connect ? I'm on Orange ro and we have VoLTE and VoWiFi.
