Goodnight everyone .

Look my situation .

Bought an S4 i9500 the week of release in the U.S., at the end of last year the outer glass cracked a few weeks later I was replacing the screen with the technique of the " hair dryer " and ended up damaging the underside of the touch . The phone continued to function normally , with the exception of the bottom that was damaged . I bought a screen in mercadolibre of a seller with 100 % positive rating and over 300 sales , having exchanged the screen , the LCD showed the images perfectly , but the touch does not respond to touches of my fingers . I sent the screen back , he said the screen was fine, but he sent me a new one and the problem remains the same . Detail , with the old screen ( original ) I can feel the touch works, since the cell responds with vibration error when the default password . According to detail , my phone is rooteado with " Cooface CMM recovery 3.0 " .

What do you think it might be?
Some incompatible hardware or software of the LCD screen with cooface firmware or the database itself from the phone?
Some hardware defect motherboard ? Even working with the original touch screen damaged ?

What do you think it might be? Thank you!

Have you tried flashing a ROM to see if that fixes it

I did the "factory reset/wipe data", is not the same?

Is there a chance to be a hardware problem? In motherboard?
Thank you.
I would try starting from scratch with 100 % stock by Odin flashing full wipe tar of the same bootloader version you are on...you would again have to root and get recovery back...may fix it by just flashing...but the stock ROM has all the debugging tools and utilities to possibly recalibrate touch...I think on stock ROM there is a mode that allows you to calibrate all touch related and also test hard buttons...

I installed a CM 11 and the touch is working.

Now, I will install a stock rom, because I want air view, air gesture, camera working, multi-windows, samsung apps, etc...

But I have a doubt.

I bougth the phone on U.S., and I use in Brazil

In sammobile there is no firmware of USA, Can I use a Brazil firmware?

the model is i9500

thank you

If it says its for i9500 then it should work...if you have networks issues you may have to change apns to fit the service for your area/network
