So I have seen many people trying to edit the build.prop to get small arrow that makes navigation bar appear/disappear. Many people sometimes brick their phone in trying to do so. Some people don't root their phone to avoid voiding their warranty.
SO here is quick solution for the problem
1.Download the attached zip. and unzip it.
2.You will find a folder HuaweiBackup after unzipping.
3.Now put this folder in your sdcard or internal storage.
4.Open Huawei backup software.
5.Select restore from sd card.
6.U will see an option of restore having only settings.
7.Press it And U will see the small arrow on Navigation bar.
Please Tell If This Method Works. Hope it Helps.
Ignore my grammatical mistakes as English is not my first language.
But unfortunately it doesn't allow me to restore in the backup tool.
Please could you assist? I've tried all kinds of folders. Even tried making a backup and placing it in the same folder.
I have a H60-L04 without root
Seems that the backup version I have is 6.30.36.L whereas the one you included in the RAR is 6.2.65 - it won't let me install your version either.
I have also tried this without luck as I can't find the Navigation bar option.
