I am not responsible if you don't know
what you are getting into and end up messing up your phone

In order to root K6 Note you need to do the following,

1. Unlock boot loader. how to do that follow here >>
http://lenovo-forums.ru/topic/21685-...а-bootloader
( It will Wipe all Data)

2. Install Twrp from here>>
http://lenovo-forums.ru/topic/21687-...-by-sevenmaxs/

3. Modify boot image and flash modified boot image with Carliv Image Kitchen from here >>
https://forum.xda-developers.com/and...droid-t3013658

4. Changing Values in boot.img
Unpack the boot image using the above tool, once unpacked go the unpack folder then into ramdisk folder and edit the default.prop using notepad++ or wordpad
Change the value of the following lines
1. ro.secure=1 to ro.secure=0
2. security.pref_harden= 1 to security.pref_harden= 0
(Change only 1 to 0 nothing else & do not forget to save the file )
3.Once done repack the boot image using the above tool.


5 .Flash the modified boot.image through fastboot, how to flash through fastboot refer here>>
https://forum.xda-developers.com/sho....php?t=1752270

6. Reboot into recovery and flash supersu from here>>
https://download.chainfire.eu/1001/S...perSU-v2.78-20

The supersu installation should be successful now. reboot and you will see supersu app in the app drawer. Cheers

(P.S I have attached the modified boot image for firmware k53_s123_170216_ROW, so no need to modify the boot image if you are on this firmware.)

Sounds interesting thanks as I keep getting errors trying to flash SuperSU or Magisk.
I'm on firmware k53_s123_170216_ROW so I will be able to use your boot.img but how would one go about getting the boot.img to modify ? The Nandroid backup is in the boot.emmc.win format and the whole partition I suppose ?

Oops so I flashed your boot.img :
Quote:

tools>fastboot flash boot boot.img
target reported max download size of 535822336 bytes
sending 'boot' (24894 KB)...
OKAY [ 0.816s]
writing 'boot'...
OKAY [ 0.331s]
finished. total time: 1.151s

At the end on the screen it says in green at the top "flashing boot ...", rebooted into TWRP 3.0.3.0 with long "VOL UP+VOL DOWN" + "POWER" press.

Tried to install :
- UPDATE-SuperSU-v2.78-20160905010000.zip (the one you mention)
- SuperSU-v2.79-201612051815.zip
- Magisk-v12.0.zip

But they all fail unfortunately, same error message as before flashing your boot.img :
Magisk12 error :
"Unable to unpack boot.img"

SuperSU error :
"-Extracting ramdisk
--- Failure, aborting"

My model is K53a48

---------- Post added at 08:50 AM ---------- Previous post was at 08:36 AM ----------

ok, I updated to TWRP-3.1.0.1_K53a48_by_SevenMaxs.7z and I was able to flash SuperSU-v2.79-201612051815.zip without errors. All booted up and SuperSU in the app drawer and rooted, thanks for the tips, man !

A few more questions if I may :
- is there a stock recovery to put back the K6 Note in factory mode ?
- how does one go about getting the boot.img out of a device for patching ?

Why don't you want to use the patched boot.img ?

You tried with the new TWRP-3.1.0.1 and it doesn't work ?

So I need to flash the modified boot.img to flash the updated twrp and then to flash the supersu.zip successfully?

I Mean flash the modified boot.img and the updated twrp will work?

You cannot flash supersu without the modified boot image.
You need to flash the recovery and modified boot image to successfully flash supersu.

To receive OTA's you need to be on stock recovery, and stock boot image without any modification to the system partition.
