Xiaomi Mi2: MiFlash guide

We talked a lot about the terminal Xiaomi Mi2 and we have seen more ways to install a ROM, but we have not yet talked about MiFlash, the tool for flashing ROMs directly from PC. But be careful! This procedure is recommended only in extreme cases, an error could make your phone unusable and even if there are methods on the network to wake it up, it is better not to test them on your skin. So be careful, but above all do it only if you really need it

Before starting, we need to specify some basic points:

the ROMs we have seen so far are in format .zip, while those necessary for MiFlash have extension .exe
a Windows PC is required
it is recommended to use a laptop with a charged battery, if the PC goes off during the procedure, you may not be able to recover the terminal
if you have installed a cwm recovery with active dual boot, you must disable it (this will delete all data, make a backup before proceeding)

Required files

Download MiFlash | Download in English
Download the ROM | Download in English
Which one to choose? You will notice many ROMs, divided into Development e Stable, again divided into versions Zip e MiFlash, available in versions (MIUI) V4 and V5. Therefore choose the version MiFlash, with MIUI V5 version and what you prefer between stable and development, since they are a bit dated. Therefore it is preferable to update with an updated version at the end (obviously with the traditional method, from recovery or updater)

Method

Extract the downloaded files into two separate folders
Start MiFlash
Choose the extracted file of the ROM fastboot via the button at the top left: Browse
Using the key Advanced, instead choose the script to use from the following available 3
– flash_all_wipe.bat: erase everything! Format both data partition (system) and external one
– flash_all_except_storage.bat: format only the data partition (system)
– flash_all_except_data_storage.bat: does not format neither the data partition, nor SD
Then press Ok
Start the terminal in fastboot mode using volume key - e power button, then connect it to the PC
The drivers will be installed, at the end press refresh top right and you should see your terminal
All that remains is to press Flash to start the procedure
Finally, the terminal will start automatically, so be patient until the end
