Zip file installation

1. the files you want to flash on the device. In most cases these are firmware, additional components or patches in the format * .zipbut TWRP allows writing to memory partitions and images of files in * .img.

2. Carefully read the information in the source where the files for the firmware were obtained. It is necessary to clearly and unambiguously clarify the purpose of the files, the consequences of their use, the possible risks.

3. Among other things, the creators of modified software packages published on the web may notice the need to rename their solution files before ing. Generally, firmware and plug-ins distributed in * .zip DO NOT unzip with a filing cabinet! TWRP handles exactly this format.

4. Copy the necessary files to the memory card.

   To perform the operation, press thebutton. "Clean up" ("Clean up"). On the menu that appears, slide the special procedure unlock "Swipe to Factory Reset" ("Swipe to confirm") to the right.

   After the erase procedure is finished, the following will be displayed "Successful" ("Done"). Press the button "Behind". («Back») and then the button at the bottom right of the screen to return to the TWRP main menu.
