Brush package is usually divided into two types, that is, the card brush package mentioned by the landlord, which is generally in zip format, and the line brush package is generally in tar format. The card brush package is simple and convenient to brush, and there is no need to connect a computer. You just need to put the brush package in the memory card of your mobile phone and enter cwm. Generally, the line brush package needs to be connected to a computer, and the corresponding tools are downloaded. After entering the line brush mode, the mobile phone will be brushed. However, some brush bags, as the landlord said, are all in zip format. How to judge this? Then you unzip this brush package. If there are files in tar format and other files in it, it is a line brush package. You need to unzip this zip package and brush the line. Otherwise, the brush package without this file is a card brush package. Just use the cwm brush of your mobile phone directly! A little extra explanation, the risk of card brush turning into brick is smaller than that of line brush! Answer finished, hope to adopt!
