If you have bought phone long time before with 4.1.2 then TPUpgrade process is very important.
Some experienced users can upgrade from 4.1.2 to 4.2.1 and perform TPUpgrade process which is required to be done carefully. After upgrade of rom, this TPUpgrade process runs automatically for one time and while it is in progress, user should not touch the screen of mobile until next message appears. Otherwise TPUpgrade fails and phone is bricked.
Coming back to Custom Rom discussion.
Generally custom rom can not damage your hardware because its just a software and at least it cannot damage touchscreen physically. But sometimes touch may stop working if there is any problem in rom or the rom file is corrupted or any other unknown reason.
The solutions is you flash any other custom rom or especially flash latest Stock Rom. Either recovery method (flash from recovery) or SPTools method (flash from pc). Mostly SPTools method solves any such wierd issues.
Hope this helps. Good luck.
Thanks for ur kind reply. Really ur answer means to me a lot.
Now I can safely assure that Custom ROM can make Digitizer not respond due to software error, but cannot damage the same (must work with other Custom ROM or Stock ROM)
For ur kind information, I Had 4.2.1 (updated from service center) before rooting (CWM recovery).
After the problem I flashed TWRP recovery with SP Tool and even in recovery mode the touch didn't responded.
After that I flashed Stock ROM using SP Tool and still same result.
So Surely it must be a hardware failure.
Once again thanks for ur timely reply, if there is anything else I missed out please inform me.
