So let’s get started with a little bit of history. I’ve decided to write a short manual for newbies (just like me) who have just bought Redmi Note 2 device with MIUI.
As for me, my previous device was LG P9 & Samsung, and I’m really enjoying my new phone, it just seems may be a little small 😉
Device is made pretty damn good, the camera is quite good and battery lives long enough for me. MIUI seems very pleasing, everything works. Device actually works really fast, everything runs without any lags. But if you want to make it perfect, you’ll have to do some work.
Fortunately everything is fine and new firmware is released almost every day ….)
It all started like this: I ordered Xiaomi Redmi Note 2 from online store, waited for 14 days and finally device was in my hands. And like regular user, who used to buy working devices from store, I was a little bit confused. Normally you just need put sim card and you’re done. Not this time. I saw unknown firmware 66.66, which really does not work.
So I started searching for appropriate firmware while sweating at every manipulation with phone. In the end, it turns out everything is quite simple, the main thing is not to hurry.
Grab a pack of beer and let’s begin.
Before you did any manipulations with your phone it is very important to make NVRAM (!!!) backup. It will come in handy if something goes wrong.
NVRAM is the IMEI, and it is customized for each phone. This can be done by using custom recovery (TWRP), or by using script from this guide.
I did it with TWRP 126.96.36.199 bilingual edition for Redmi Note 2.

Firmware setup using custom recovery
Attention! Before doing any updates make a backup of your data! This method will remove all installed software and files.
I’m using this method when I change MiuPro to AOSP or Xiaomi.eu and back.
If you just bought your device and decide to install firmware updates, you can immediately start the process. If you’re already using your device (some apps are installed, custom settings, e.t.c.) make sure you’ve made a backup. You can use Titanium Backup or default Miui tools. Don’t forget to copy backup files to SD card or PC.
Copy firmware files to SD card or USB flash. Storage must be formatted in FAT32.
Enter the recovery using one of the method below. Method 1: Hold power button + volume up button at the same time. As soon as you logo, release the power button while keep holding volume up button. Recovery tool should start. Method 2: Update > Press the three dots at the top bar (…) > Select “Reboot in Recovery”.
Select “Wipe” > “Advanced Wipe” and put checkmarks near “Dalvik Cache”, “System”, “Cache”, “Data” and “Internal Storage”. After you’ve put all checkmarks, swipe to the right. P.S. If you put a checkmark near “System”, some devices may show installation error. In order to avoid this you just need to reboot recovery. And then go to step 4.
Return to main menu and enter the “Install”. In the top row, selectthe folder where firmware files are located.
We found firmare files, select it and swipe to the right to confirm.
After firmware installation is completed, you’ll see a screen where you can make “Wipe” and “Reboot” after.
Wait until firmware installation is completed.
Firmware for FDD & TDD, as well as for Prime are absolutely identical. At least for this moment.
Starting from 5.10.15 Xiaomi started to sign their firmwares with PRIVATE key. This means that: using STOCK (native, mi) recovery you can install only STOCK English – Chinese firmware. If you try to install custom firmware you’ll see “signature verification failed” error. Custom firmware can be installed only using Custom (TWRP) recovery.
