How to Unroot, Restore to Stock, Unbrick, and Manually Upgrade Sprint Galaxy J3 SM-J320P

Prerequisites:

Before you proceed prepare these necessary things as follows so you’ll not  messed-up your phone:

Backup all your personal data – Use “Samsung Smart Switch for PC (Google it) to easily make a backup of your Contacts, Messages, Applications, Pictures, and Videos, so that you will not lose it. You must do this because the recent firmware packages will wipe out your device stored data.

Recharge the device battery – Make sure that your Galaxy S7 battery is fully recharged to ensure its stability. A power failure during the installation process may harm your device.

• Prepare a PC as this process will not tend to work in Mac computers.

Enable OEM unlocking mode – This thing wan’t there before during the old times, but if this feature is already enabled in your device.  Just go to Settings > About device > then look for the firmware’s Build number and then tap that build number for around 7-times until a message pop-up that says something like “Congratulations you are now a developer!”. Then hit back in Settings > About device > Developer option > OEM Unlocking.

Enable USB debugging mode if you are having issues connecting your device to the computer try to enable this option.go to Settings > About device > Developer option > USB debugging.

TURN OFF the Reactivation Lock – This also necessarily needed if your device already have this feature. This is only needed if you already turned it ON, from which you cannot modify the system when and if it’s turned-ON.

To do this just got to Settings > Security > Reactivation Lock, and then uncheck the Turn Reactivation lock on.

Grab these necessary tools

  1. Odin3_v3.11.1  downloader or the latest version –  This is best for flashing the Android 6.0.1 Marshmallow stock firmware
  2. USB Driver – only needed if you haven’t installed the latest Samsung Smart Switch in your PC.

Extract/Unzip the download stock firmware

Extract the downloaded firmware. Use any decompressing program you have had in your computer.

Reboot the Galaxy J3 into Download mode

Reboot the Samsung Galaxy J3 into Download Mode: Turn it Off first. Now, Press and hold the Volume Down, HOME and Power ON button at the same time. You will then presented into a “Warning Message” screen, just press the Volume Up to continue. Once the Android robot and a “Downloading” message appears. If you can’t get into it, repeat the 3-button combination again and again.

Run and Configure Odin3 Flasher

Run Odin3 flasher program. In Odin window DO NOT tick the option box that says ‘Re-Partition’. Leave the  ‘Auto Reboot’ and ‘F.Reset Time’ check-marked by default.

If the stock firmware packaged contains a single tarball only, then simply load it in the AP button. But the if the packaged contains individual binary files  just load each firmware binary files to their designated slots in Odin such as: the “BL” (bootlooder) file goes to the “BL button/slot“, same goes about the “AP” (phone), “CP” (modem) and the “CSC” (consumer code) files. Once loaded, you need to wait for a while as Odin3 will check the files compatibility and authenticity.

Connect the Galaxy J3 into the computer

Connect the Galaxy J3 to the computer using the supplied USB data cable. In Odin window, the ID: COM box will turn to a bluish color when the phone is properly connected and it’s an indication that it’s recognized with Odin. It also states as “Phone Added! in the log-cat.

Begin flashing the stock firmware

When all is set and you are ready into flashing just simply tick the ‘START’ button located at the lower part of Odin.

Avoid interrupting the process

DO NOT disconnect nor do anything when the phone is already in download mode and flashing status. You’ll messed up the phone if you accidentally interfere the installation process. Wait until a word “PASS” appears on the left side of the Odin screen, it is an indication that the installation successfully completed. However, if you get failed errors, check the USB connection condition, repeat the whole process or read the troubleshooting section below.

Wait until it says Pass!!

Odin3 will display a message that says “PASS!” when the process finishes. Wait until the phone completely reboots, then unplug it from the computer. However, if you might get the error message “FAILED!” you may check the troubleshooting procedures down below.

Troubleshooting if and when firmware flashing failed

Do performing factory reset after flashing is necessary when the device previously runs on any modified ROM and unofficial firmware images?

This process is optional, but this method can get rid of the unwanted bootloop, rebooting issues, freezes and lag issues after the new firmware installation.

Press and hold Volume Up+ Home+Power button, then select the Wipe Data/Factory Reset, to gain a fresh firmware installed.

Odin keep on failing and I’ve tried everything from A to Z but still nothing works. What else can you suggest?

You may have attempted rolling back to an older firmware version. Noting that newer updates will not allow you to downgrade to an older firmware version.  This is why Samsung and Google frequently released the Android security patches in a monthly basis. You must carefully keep an eye of each firmware build version. Please check back my insights about the stock firmware above.

Also,  if you’ve use the stock firmware to unroot and or restoring back from a modified system images but cannot get through the during the flashing and you get Odin3 fail error, you may first sort  things out like what root kernels and custom ROM, and any modified system images you have previously used before and try to find an answer to why it causes a flashing failure. Sometimes the problem is not on the stock firmware but lies in the modified system image you’ve used that causes the problem of not letting it through pass in Odin3.
