[Redmi Note 2 Q&A, Help & Troubleshooting] maxx_hr:
OK,

lets's start.

1. If you rooted, please install terminal app on device (eg:https://play.google.com/store/apps/details?id=jackpal.androidterm)

You can do all of it and over adb, but...

2. Open terminal, and type:

su

hit enter

3. Save your present recovery, type:

dd if=/dev/block/mmcblk0p8 of=/storage/sdcard1/recovery.img

hit enter, and on root of your SD card you can find recovery image. Move it somewhere on safe.

4. Collect some info, type:

cat /proc/partitions

ofc hit enter

after that:

ls -al /dev/block/platform/mtk-msdc.0/by-name

then:

cat /proc/emmc

and result MUST look like this:

cat /proc/partitions

If your layout has differences do not proceed further.

5. Download (I use it now) TWRP 3 from: https://mega.nz/#!dwEg2DaZ!rYZr59M__x2tsYGm4jPzvUSHUZ4dnIEEYc4Du7lo_x8

and place it on root of sd card (/storage/sdcard1/recovery.img)

Next step is extremely sensitive, but I flash recovery on my device several times on that way.

6. Open terminal app (on your device), and type:

su

hit enter, and type:

dd if=/storage/sdcard1/recovery.img of=/dev/block/mmcblk0p8

enter

now you have TWRP

type:

reboot recovery

and if you enter (finaly) recovery, don't miss to swipe to allow modifications

Good luck.
