As mentioned a few weeks ago in the video-viewing, an aspect that left us behind this new born in the Xiaomi family is the upgrade process.
It seems that for the RedRice, HongMi code name, there is no OTA update method and, even strangely, there is no MiRecovery version that allows updating the ROM directly from Updater.
Here's why this guide.
First of all I want to point out that this is NOT the only guide available for updating RedRice but it is the one I found best. True, it can be done by phone, but once properly configured, PC use simplifies operations.
Let's start with:
ADB Driver for Windows 7 / 8 - Indispensable for using the vROOT program correctly
vRoot - A simple tool that allows you to make Root to Xiaomi Red Rice
MobileUncle - Application that can install the modified recovery for updating the ROM (Requires ROOT)
CWM - Recovery modified for the WCDMA version of the RedRice (Extract the Zip)
Multilanguage ROM "Stable" 3.11.29 - Stable version of the Multilanguage ROM for WCDMA RedRice
Step 1: Install ADB Drivers
If you have already installed ROMs, connected smartphones with various toolkits, etc ... probably these drivers will already be installed.
If not, proceed with the installation of the ADB drivers downloaded previously.
NB. On Windows 7 e Windows 8 it is necessary to disable the digital signature drivers setting before these drivers can be installed correctly.
Step 2: Installing vROOT
Install the vROOT program by double-clicking on the previously downloaded executable.
Step 3: Smartphone Prep
Go to Menu (Soft Left Button) -> Settings -> About Phone
TAB 7 times below on "Android Version" to enable "Developer options" in the settings.
Go to Menu (Soft Left Button) -> Settings -> Developer options
and enable "Enable development" and "USB debugging"
Step 4: ROOT
Start vROOT previously installed.
It will start in "Waiting" mode until you connect your phone via a USB cable
Connect the RedRice to the PC via a USB cable. If the ADB drivers are correctly installed, a message should appear on the phone asking you to accept the debugging of the phone from the PC. Obviously answer yes.
If the phone is not connected on vROOT, close vROOT and restart it.
Once the phone has been detected, just click on "ROOT" and wait a few seconds.
RedRice should reboot. Done? Good! Your RedRice is now rooted!
Step 5: Copy tools and ROMs to your device.
If you have not already done so, decompress the CWM-WCDMA.zip file and extract the recovery.img file.
Copy the recovery.img, mobileuncle.toolbox_327.apk and ROM files (all zip, without decompressing) to phone memory (PHONE MEMORY, NO SD MEMORY SD).
If you do not see the phone memory on your PC make sure you have enabled "Mass Storage" in the RedRice notification area.
Step 6: Exchange Recovery
Once you have copied all the files on your phone, unplug the RedRice from the PC.
Using the file manager, install the mobileuncle.toolbox_327.apk application.
At the end of the installation, start Mobile Uncle. At the first start you will be prompted to confirm the ROOT permissions, press "YES".
Launched the Mobile Uncle go to "Recovery Update" and select recovery.img (the modified modified backup previously copied).
Mobile Uncle will ask you first if you proceed, once installed it will ask if you will restart the phone in the new recovery. Of course, answer "Yes" to all messages.
NB. It may happen that the phone restarts normally without getting into recovery. Repeat operations within Mobile Uncle
Step 7: ROM Update
We are in the new recovery but ... tatatataaaaaaannnn is EVERYTHING in Chinese! Now how do you do it?
Well, just follow the pictures (COMMANDS: Vol + and Vol- to scroll up and down and POWER to confirm):
1. Select the second entry
2. Select the last word
3. Select the last post (the ROM you downloaded and transferred to your phone)

5. Wait for the installation to finish ...
6. Select the last entry ("back")
7. Select the fourth item
8. Select the second entry
9. Select the first entry

Step 8: Enjoy the new Multilanguage ROM!
It will take a few minutes to launch the Multilanguage ROM ... wait!
