My Samsung Galaxy S4 Zoom phone has been automatically

This answer was rated:

My Samsung Galaxy S4 Zoom phone has been automatically upgraded to firmware version: PDA:NH1/Phone:NH1/CSC:NG1 (BTU), and ever since it reboots randomly, the zoom lens extendes and retracts without warning and the phone has become totally unreliable.

Is there any way to down grade to the original firmware version?

Thanks for your help.


Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Yes, there is a way to downgrade to the original firmware. To do that, you have to manually download the firmware file and use the Odin application to flash that firmware to your S4 Zoom.
On your computer, download and install Samsung Kies application from here -->
Then download the correct firmware for your phone from here :
(In the above site, enter the exact model number of your device and click Search button. From the resulting page, download the correct firmware version you want)
After you have downloaded it, you will get a zip file. Open it or extract it and you will get a .tar.md5 file and some other files. The tar file is the firmware file.
Then follow the steps below.
Download the Odin application from here :
or from here -->
Then open Odin application and follow these steps below;
Put the phone to Downloading mode. To do that, turn off the phone. Turn it on and immediately hold down Volume Down and Power at the same time to boot into downloading mode. Volume Up to confirm if asked.
Then connect the phone to the computer with the USB cable. A message saying "Added!!" will appear in Odin's message box at the bottom left of screen.
Click the PDA Button, and choose the .tar.md5 file (the firmware file)
Make sure Auto Reboot and F. Reset Time options are enabled. Also make sure the Re-Partition checkbox is not selected.
Don't make any changes to Odin. Click Start. Let Odin finish the process. Once it finished, it will show a Pass in the top left. Please let me know how it goes.
Make sure you download the correct firmware file for your phone. Also when you do this, you will lose everything from the phone. Let me know how it goes.
Refer this Youtube video -->
(the first part of video that is the firmware downloading part might be a little different when you do it now)
Hello Kevin, I'm just checking. How is it going ?

Thank you so much for your help. Whilst I could not get the previous version of the firmware to work on the phone, however I did find a more recent version that the version I was having problems with, which had not automatically downloaded to the phone.

I have now replaced the firmware with this newest version, the phone appears to be working OK and hopefully over the next few days I will be able to see if this has fixed my problem.

Once again many thanks for your help.
