[Completed] How to repair Karbonn Titanium Octane Plus?

[SampathFrnd4Ever]

I have Karbonn Titanium Octane Plus from past 2 months(my 4months savings). I wanted my phone to have Android 'L' so i searched in google but couldn't find any. But found some custom rom of cyanogenmod cm11 of elephone. Installed it using TWRP v2.8.2.0 as shown in tutorials with all the adequate software to be install for my laptop. After intalling cm11, Android version got upgraded from 4.4.2 to 4.4.4. I was happy and exited for some period. after few days felt the earlier os was better as it had video recording and FM player. so wiped the phone to install stock rom of Karbonn Titanium Octane Plus but couldn't as the error occurs shows as mentioned below:

E : Unable to mount ' /system'

Please Help........

Hello,
Welcome to XDA.

When you flashed TWRP did you make a nandroid backup of your stock ROM in TWRP? Making backups in custom recovery is the most valuable part of having custom Recovery. If you did make the backup of stock then all you need to do is select the restore option in TWRP and restore your nandroid and you should be fixed.

If you didn't make the backup then you'll have to download your stock firmware and flash it via PC and your device's compatible flashtool.
you should find what you need in the thread linked below in post #3.
