Initial comments

Note that there are different models of the Samsung Galaxy J3. To see which one you have, if you still have the original recovery image on your device, power it off and then hold down the home button, power button and volume up button. See at the top of the phone's screen for the model code. If it's J320FN(string of characters) you're probably good to go. If yours is J320F it will probably be very similar to port.

Alternatively, simply remove the back cover and battery. The sticker underneath should read: MODEL: SM-J320FN.

How to enter flash mode

Hold down home button, power button and volume down button for a number of seconds. Then once a prompt appears on screen, press volume up. You are now in download mode (it will say so on the screen).

Installation

Flashing works since pmaports!4315, so the image can be installed normally.

TWRP

Firstly, download TWRP from the XDA developers page. The download is in the section labelled "Attachments".

Use heimdall to flash recovery.img to the recovery partition of your device:

  • Put it in download mode (see above)
  • Connect to computer
  • Run heimdall detect to see if heimdall can see it.
  • Run heimdall flash --RECOVERY recovery.img, making sure you are in the directory with recovery.img

Charging-related recommendation

Note Information in this section may be outdated.

Disconnect the cable when you turn the device off. The device freezes on the charging splash screen if it's not disconnected.
