Hisense T92 is equipped with an optimized version of android 2.2. 1 native system, so its official and background services do not provide firmware ROM and services for upgrading the system.

If you want to upgrade, you can get permission through ROOT, and then brush the system firmware to solve it; For details, please refer to the forum post of using Zhuo Dashi software Zhuo Dashi Hisense T92 Brush Course, which has a high success rate. However, it is necessary to pay attention to using titanium backup before brushing, and take out SIM and SD card to avoid unexpected problems;

Choose;

1 .Hisense T92 original ROM: free navigation software is pre-installed.

2.T92 official brush package (March 3rd): system 2.2. 1

3.T92 Extreme Speed 2nd Edition Royal ◆ Dragon Gun: Pre-installed software and optimized system slimming background running ROM with power removed.

The above three packages are optional according to your own needs, but remember that non-original official packages may also cause warranty problems.

Good luck in the new year.
