How to upgrade oppo R7s Android 4.4.4 to version 5.0 or above?

First, download the rabbit brush on the computer and install it on the desktop.

1. Turn on the Qitu brush, connect the mobile phone and turn on USB debugging mode. After Qitu Brush detects that there is a model connected, it will automatically install the driver for this model. After the driver is successfully installed, it will automatically connect the mobile phone and keep the mobile phone in a normal startup state. 2. Click on the one-button brush machine and select the ROM package of the mobile phone model you want to brush. If you haven't downloaded the ROM package of your mobile phone, you can download it in the ROM market of Qitu Brush Machine. After selecting the ROM package of the mobile phone, enter the data backup interface, and the mobile phone will clear contacts, short messages, call records and applications. I suggest you back it up and restore it after the phone is swiped.

3. After data backup, the computer will be refreshed.

4. After the operation is completed, the mobile phone enters the automatic brushing mode. At this time, just wait patiently for the phone to automatically restart. If you can't restart, click Manual Restart.
