[MOD] Tethering Fix for Rogers users running AT&T based ROMs

---

Seems the AT&T ROMs have some tether protection (entitlement check) built into them that does not exist on the Rogers ROMs. So if you are a Rogers user and have flashed an AT&T based ROM then you will need to make a change to your telephony database to be able to get tethering working.

This problem probably is not unique to Rogers and probably applies to anyone who is using an AT&T based ROM on a network other than AT&T. To apply this to a different carrier you will just need to change the APN, numeric, mcc and mnc values in step 5 to match your carrier values.

Update: Turge made a flashable zip to perform this update.

Just install the zip in recovery.

Flashable ZIP (thanks Turge):

------------------------------------------------------------------
Old Instructions:

1. Use a rooted filemanager (e.g. ES File Explorer) to backup the Telephony Database (/data/data/com.android.providers.telephony/databases/telephony.db) to a safe place (e.g. /sdcard/).

2. Download SQLite Installer for Root from the Market and open the app and install SQLite3

3. Open an adb shell

4. Type the following command in to open the telephony database:

su -c sqlite3 /data/data/com.android.providers.telephony/databases/telephony.db

5. This should have opened sqlite3. If it did then type the following command in to update the database:

INSERT INTO carriers (name, numeric, mcc, mnc, apn, authtype, type, insert_by, state, protocol, roaming_protocol, carrier_enabled, bearer) VALUES ("Entitlement","302720","302","720","ltemobile.apn ","-1","entitle","internal","hidden","IP","IP","1","0" );

6. To confirm that this has been applied you can type the following:

select * from carriers;

This should list all the carriers you have in your telephony.db and the one you just added should be at the bottom.

7. Type the following to quit sqlite3

.exit

8. Type the following to reboot your phone

reboot

When your phone reboots it will work with standard ICS/Sense tethering!

I tried to write an ADB script to do this but ran into problems with the INSERT command so I just wrote some instructions instead.

Someone more skilled at scripting could probably build an ADB script pretty easily I am sure.

I was bored, so I made you a recovery flashable zip to perform your changes

If you want to find out if it worked, just type "cat /tmp/recovery.log" via adb shell after flashing the zip. The output should look like this:

I just created a hack that will unlock the tethering on AT&T based ROMs without modding this setting, so I'll post it in a couple when I get the chance

This way is much better, it is universal.

Yeah the other method is carrier agnostic/universal but it needs to be updated for each new AT&T RUU.

Using the method in this thread you could create a flash file for each carrier and that flash file should be usable on any new AT&T RUU.

The method in this thread seems safer too because you are just modifying a few rows in a database instead of replacing functionality/executable code (which I think is what the other mod does).

In fact ROM creators could insert Entitlement rows for all the common carriers in the Telephony.db and we wouldn't need to worry about any of these mods.

I just flashed it and tried to run a wifi-hotspot and it doesn't seem to work.

I do get a different message now saying that if I want this to work, I should call someone from att or dial 611.

Anyone else try this?

i tried it and got the same result as you....

Same here, no luck. Rooted stock 1.85 AT&T, connected on "4G" (HSPA+).

(ADB method)

That is odd...hmm.

With the ADB method did step 6 (select * from carriers) show the new line that you added?

Also are you in Canada on the Rogers network? This is only for Rogers.

Edit: If you are both on HSPA+ and not LTE then maybe that has something to do with it. The APN that I used was for LTE. You could try replacing ltemobile.apn in the instructions above with rogers-core-appl1.apn.

I would do revert to the backup of your telephony.db first before I tried this though as I am not sure what happens if you have more than one Entitlement APN for a carrier. It probably just uses the first one in the list which would mean adding rogers-core-appl1.apn would have no impact.
