How to Enable LTE on iPhone 5 Model A1428 for T-Mobile?

As we have reported previously, T-Mobile is now an official carrier of the iPhone. T-Mobile will be selling a new type of iPhone 5 that will support the carrier's new LTE network. Because of this, Apple had to do a hardware refresh of the A1428 model iPhone 5, which is sold via AT&T and a simple firmware update will not bring compatibility to the new LTE network. This becomes a problem because if you own an A1428 iPhone 5 and wish to switch to T-Mobile, you won't be able to access the LTE network. You will be required to buy the new handset. Fortunately, the folks at Leimobile has found a neat workaround, as long as you are jailbroken.

Enable LTE on iPhone 5 for T-Mobile

This trick will enable you to access T-Mobile's LTE AWS connectivity on your A1428 iPhone 5. KEEP IN MIND: this will ONLY work with an AT&T iPhone 5 or with an officially Apple unlocked variant. If you have a Verizon iPhone 5, you are out of luck. We are also going to access Cydia, so this is for jailbroken iPhone 5s only. To jailbreak your iPhone 5 on iOS 6.x.x (except 6.1.3), refer to this guide (the process should be similar, except for the firmware used).

We're sharing this to you for the sake of information and unfortunately, we weren't able to test this. However, the feedbacks are mostly positive, so I think it's worth a try. Just do so at your own risk.

  1. Launch Cydia from your Springboard.
  2. Tap "Manage" at the bottom of the screen, then tap "Sources".
  3. Tap Edit from the top right portion of the screen, then followed by a tap at the Add button.

  8. After rebooting, launch Cydia and search for iFile. The package is free but you can choose to buy the product in order to access all of its features (it's worth it).
  9. Install iFile. You can reboot your iPhone again just to be on the safe side, although it's not needed.
  10. After installing iFile, close Cydia and click on this file from your iPhone and tap “Open in iFile”.
  11. Once you're in iFile, tap “Unarchiver” and 3 files will show up above T-Mobile
  12. At the top, tap “Edit” and click the dots with a check mark next to carrier.plist, carrier.pri, overrides_N41_N42.plist, and overrides_N41_N42.pri
  13. Then, you need to tap the clipboard icon located at the bottom and select "Cut".
  14. Now tap “Done” at the top, followed by a tap at the house icon at the bottom, then a tap to Library, then tap Carrier Bundle.bundle (the one in blue), and then tap Edit at the top again and tap the clipboard icon. Select “Paste” and it will auto inject the carrier files into the carrier folder overwriting the other files. It is recommended that you backup these files just in case something goes wrong.
  15. After the files have been placed, exit iFile and restart your iPhone. After restarting, allow it to acquire signal and display the T-Mobile logo, then go to where you edit the APN settings (Settings > General > Cellular) click Reset Network Settings.
