[T-Mobile Samsung Galaxy Note II] theromanone:
So here's the story, I followed these instructions to allow tethering to my rooted note ii (stock rom, no flashing, no counter trip), which all worked fine until yesterday morning I now have only Edge, which barely works. I tried flashing the APN below again, to no avail. I had to call tmobile and do a new APN with their settings, which I will post under the 1-30 instructions. After doing that, 4G worked, but after reflashing the APN for tethering I have no data. After doing the t-mobile instructions, I still only have Edge again. Help anyone?!:

01. Have a T-Mobile T889 Samsung Galaxy Note 2

02. Download these files: http://xdaforums.com/atta...1&d=1351716949

03. Extract files to folder on Desktop

04. Root your T-Mobile T889 Samsung Galaxy Note 2

05. Once rooted, make a COMPLETE backup using CWM or Titanium Backup (I did BOTH just in case, I like to be double sure I have a backup)

06. Once backed up, go to Google Play Market and download "APN Backup & Restore"

07. Once installed, open APN Backup & Restore and press on "OK" on the warning message that comes up

08. Close APN Backup & Restore (from task manager too, just in case)

09. Open Titanium Backup and press on Backup/Restore

10. Find the application "APN Backup & Restore" and long press with your finger on it

11. Once menu comes up, press on "Convert to System App"

12. Once done, close Titanium Backup (from task manager too, just in case)

13. Open APN Backup & Restore and press on "OK" on the warning Message that comes up

14. Press on the menu button on the phone and press on "Disable ICS Check"

15. Close APN Backup & Restore (from task manager too, just in case)

16. Open APN Backup & Restore and press on "Backup APNs"

17. Select a name or leave the one in there

18. Once backed up, close APN Backup & Restore (from task manager too, just in case)

19. Connect your phone to your computer

20. Once connected, navigate to your phone drive in My Computer and go to "Phone > ApnBackupRestore" > Copy the created XML file to your computer (once again, just in case)

21. While still in the "Phone > ApnBackupRestore" folder copy/cut/paste the "T-Mobile-APN.xml" file to that folder

22. Once the file has been copied to the "Phone > ApnBackupRestore" folder, open up APN Backup & Restore application on your phone

23. Once open, press on "Delete APNs" and press "Yes"

24. Once deleted, press on "Restore APNs" and select the T-Mobile-APN.xml (the one we originally copies from the zip folder that needed to be downloaded/extracted to a folder on your Desktop, and press "OK"

25. It will then restore the newly modified APN file

26. Close APN Backup & Restore (from task manager too, just in case)

27. Go to Google Play Market and download "Tethering Widget"

28. Once installed, go to the APPS icon on your phone and select Widgets tab on top and drag the Tethering Widget to a new page

29. You should now be able to successfully enable native tethering via the Widget

30. MISSION COMPLETE

*NOTE: DO NOT GO INTO THE ACTUAL T-MOBILE HOTSPOT APPLICATION AS IT WILL OVERWRITE THE APNS AND TETHERING WILL NO LONGER WORK. IF THAT HAPPENS, REPEAT STEPS 23-30.
