TSP firmware upgrade revert

[dtandukar]

Hello, I upgraded TSP firmware through *#2663# and now bottom and right part of my touch screen (about .5 cm) is no more sensitive. How do I revert to original TSP firmware or is anything can be done?

Looking forward to hearing from all of you. 

Best regards, Deependra

No idea what you were thinking, and why you thought it was a good idea?

You could download the correct Samsung Firmware for your device to your computer & Flash it with Odin, or visit a Samsung Service.

thanks RedDogRabbit for your quick reply. Can i download firmware for the TSP and upgrade

I think that you might have to Flash the FULL Firmware for your device.

You need Samsung's USB Drivers installed on your computer.

Odin installed on your computer.

You can use Frija to download the CORRECT version of your device's Firmware.

For instructions on how to Factory the Firmware with Odin, you can see my post in the link below, or Search on XDA.

Still no idea what you were hoping to achieve? 

Flashing anything or modifying the firmware for any part of your device has risks, as you have discovered.

i had a problem with my touch screen so I upgraded the TSP firmware using the code *#2663#. after upgrading bottom edge and right edge of the touch screen are not working about .5 cm of both the sides), rest of the panel is working fine. So all i wanted to do is revert the TSP firmware. 

I hope it is clear now. 

Best, D

I had a touch issue on a previous device. I resolved it with a Factory Reset. Ultimately a lot faster & simpler than Flashing the Firmware.

Hopefully you'll manage to resolve your issue.

factory reset did not work. even flashing won't work according to other users with similar problem. this needs to revert or upgrade to newer version of the TSP firmware. but don't know how to revert or where to get newer version of the TSP firmware.

What was the problem with your touch screen? 

But sure, don't take my suggestions. Visit a Samsung Service center & get them to fix it.
