[Micromax Canvas Knight Questions & Answers] Mr.Ak:
Hey bro,sorry for late reply.I was a bit busy this days.

Okay so as you say(as you guessing) the power and touch is not working..so first of all just try flashing stock v3 rom through sp flash tools, I know its new for you and maybe you aren't even know what I'm talking about so lemme just help you there...

www.canvasknightroms.blogspot.in

Go to our blog and check out root section for all the info and also all other sections to get a basic idea on what you are getting into.What you actually need to do is,download a 1.1gb flash file and a software called sp flash tools and flash the file through sp flash tools and also first make sure you are setting up the drivers correctly,you can get all possible info on flashing and all the links through our blog.Anyhow as you are new to this,I will help you more on this topic if you want.

Now the ques. Possibly in your mind would be "why this lunatic guy is saying me to flash a rom(software) when the problem probably is with my power button and touch(hardware)?! Is this guy idiot or what?!

My answer would be,lol no! What I'm simply saying is that it might be a hardware issue but i have seen users practicaly getting this type of issues randomly out of nowhere but most of them just flash the stock rom and boom device back to normal as it was! Most of the time this issues due to nonalignment of software and kernel through hardware so sp flash tools is capable to solve this type of issues.

Now as flashing this all WILL format your internal storage so you might wanna consider a backup of your data.

Ok,so I'm considering that the device is still booting and fully working except touches and hw keys.and also I believe that your mtp is working(unless you have setted to other mode before touch dismantled :'( )

So just put your phone in mtp(media to phone) mode or PTP and connect through usb and copy all data in pc!

What if you aren't able to set your phone to ptp/mtp mode for storage and its on charging only mode?!

Now as your touch is not working you need to use any android screening software(just google it for tutorials and videos regarding) and it will cast your screen to pc and then you can easily set to mtp/ptp storage modes to backup data.

Now i hope that you made this far and you are already working on what i have suggested. ;)

Now my ques. Is touch working in custom recovery like twrp or philz touch? If yes! Then it's merely a software issues which will be solved by above explained method!

Depends on your luck :)

What if really your touch and hw keys are still not working after flashing rom?!

Don't ever to go to SVC guys for touch replacement and keys replacement if device isn't at warranty(which it won't probably :P) cuz they will take a month or so and charge like hell!

So what you can probably do?,

Just order a good display and hw keys through ebay or any site for A350(that way you will save a lot of money) and do the replacement yourself!

Yes it's very easy to do,just follow some a350 dismantling videos on youtube and tutorials and its easy unless you are lul and you break anything!

Disclaimer-I won't be responsible for anything you break while doing all this experiments!

Just a advice,be patient while doing all this :)

Anyhow i hope you like my suggestions so just drop a thank button as i typed such a big article just to help you :P
