How to unbrick infocus m350 (hard bricked and also soft bricked - updated for lollipop bricked users also)

Hello Friends,

I have come up with a solution regarding the hard brick and soft brick of your Infocus M350. Recently, i have purchased this mobile and had gone through the same issue. Hence i wish to give you some support regarding the unbricking of the handset.
IMPORTANT NOTE:
If you have bricked your device while upgrading to lollypop, then you need to change the text.
First open the updator-script in the below location
meta-inf<android<google<updater script.
Open the file and delete the first 4 lines in that file ( updater script ), save it and then re-zip the file. This should be done if you get boot loop while upgrading to lollipop and this is the verification of your zip. Remove those starting 4 lines and re-zip to update.zip ( do only in KITKAT update.zip).
This should solve the problem. (*Do this only if you get boot loop while upgrading to lollipop*).
After this small note, lets continue with the unbricking process,

DOWNLOADS:
1. Infocus M350 stock ROM in zip format infocus m350 stock ROM (KitKat 4.4.4) and 
   Infocus m350 stock lollipop update (lollipop 5.1)
   Download any one of the them
2. Infocus M350 stock boot Stock boot.img file 
    Infocus m350 stock recovery stock recovery file 
3. adb and fastboot files adb and fastboot files
PROCEDURE:
1. From your mobile, press volume down+power button at a time and then you will get intlo the fastboot mode. After that connect the device to the pc.
(Follow the above note if you find boot loop after the lollipop update)

2. Now copy the recovery file, kitkatboot.img and update.zip files to adb and fastboot folder. Copy both kitkat and lollipop zip files to your SD-card. 

3. Next open the command prompt window inside the particular folder.( Press shift+right click  and you will get the option called open command prompt here). 
In cmd window, type the following
fastboot devices
fastboot flash boot kitkatboot.img
fastboot flash recovery recovery.img
fastboot boot recovery.img
****If this last command doesn't get your device to recovery mode, you have to press volumeup+power at a time until you get into recovery.****

4. Now you will get into recovery mode and there you will find an option called "update from adb sideload" inside the install zip menu. Click on that option.
****If you already have a recovery, then you can start from here****

5. Now come back to pc and copy that stock ROM ( update.zip ) to the adb and fastboot folder.

6. Now in your phone, click on adb sideload update.zip. That's it . Now the flashing starts and it takes almost 5 min to complete.
