-----1st - I want to thank you for this fine work.-----
I have used this successfully with 2 different roms. Beanstalk Harmony a month ago and again today with Dirty Unicorn 5.0. Both roms had the SystemUi.apk located in the /system/priv-app folder. I found that your themer works for me only if I move the "SystemUi.apk" file to the /system/app folder. I'm not sure if this is a common issue, of if the devs are placing the "SystemUi.apk" file in the wrong place or should your app be looking in the /system/priv-app location instead. Just wanted to help. Hope I did. Also, should the OP instructions be modified with the following minor changes?
1. Download ZipThemer -
https:// play.google.com/store/apps/d...ipthemer&hl=en
2. Download the "aooga_h_to_4g_update.zip" file from
http://d-h.st/Hwy
3. At right upper corner push the 3 dot settings access icon and choose "Update Edify".
4. Verify your device is listed. It should be auto-selected.
5. Push "Browse" and select a flashable file that you have on your phone (choose the rom zip file or gapps zip file for example) but not my file.
5. Next click "Configure". You should get the toast message "Success".
6. Go back one page and then tap "+Theme" button.
7. Then use the green arrow to go and search to find "aooga_4g_to_LTE - TEST!!!.zip"
8. On the next screen you should see a check next to 4G to LTE.
9. Press the "Build It" button.
10. You will then be prompted to create a flashable "undo" file to revert the changes (may be a wise suggestion).
11. The app will then build the flashable files (One an update .zip and the other is undo .zip. Then the app will go to a Build Log screen.
12. You can now reboot into your recovery and flash the "4G-to-LTE-update.zip" or the "4G-to-LTE-undo.zip" as you need to. (Note: This name might vary, but it will always say "update" or "undo" at the end of the name.)
13. Enjoy!
