some users report a password prompt while in Twrp, just press "cancel" then go to twrp home screen , WIPE-FORMAT DATA, after formatting data , go back to twrp home screen -REBOOT-RECOVERY , after that flash the root file (make sure your root file is on an external sd card .

Please upload video for how to root,twrp and adb installing..because i m a android beginner.
Well i guess if you follow it step by step there won't be any problem.If you get stuck at some point just comment here.And installing adb is just like the normal installation of any setup files in windows.Regarding the flashing of twrp there is nothing much to do than the steps mentioned above.If you still need a video go for this.https://youtu.be/kmq2Eyzl3wA NOTE:This video makes use of files for the sd410 model,so don't use the files in that video.Get the files from this post.This video can make you familiarize the process,but steps mentioned here is slightly different.

There aren't any custom roms available till now.Try using xposed modules for improved functionality(serves the purpose of custom rom to great extent).

Internal Storage Files Missing

After I flashed TWRP and then entered it, it asked for a password to decrypt my storage. I didnt set any password for my phone so I pressed cancel after which came the TWRP menu. But once I selected the install option so as to flash the supersu file, I was unable to find my zip file in it. When I searched for solution, they said it was because my storage is encryted that I was'nt able to acces the data. They adviced to format data through wipe option in TWRP. But still no use. And to add to the problem, when I tried to reboot into system, I was left with a black screen and couln't get to the homescreen.

Please consider my problem and hoping for your fast reply.

Boot back into twrp home screen - WIPE- FORMAT DATA , after that, also from twrp , REBOOT-RECOVERY, after that, go ahead and flash the root file and then try to boot into home screen.

Thank for your fast reply. By following your steps, I was successful in rooting the phone but when rebooting back to home screen, the black screen's still there.

I guess you have copied the super su file to external sd card.Formatting data as mentioned by jide1 did remove the encryption for me.If it doesn't work do advanced wipe with only the data,cache and dalvik cache boxes checked.Note:don't check any other box.Then reboot into twrp.Go to mount in twrp and see that your external sd is mounted.Now access the external sd card in install option and you will find the files of super su.

Need stock boot.img

I require the stock boot.img so if anyone is kind enough to upload it, ill be greatful. Or if anyone knows how to extract it from the raw image, that'd also be appreciated.
