hold the “POWER, VOLUME DOWN and HOME” buttons simultaneously. You’ll be then prompted in a warning screen to continue or cancel.
Step 6: Connect the Phone to the Computer or Laptop
Once the phone screen shows in downloading mode, connect your phone to
the PC with the USB cable. You’ll then notice the upper box in Odin that
turns in yellow color., it also indicates the COM:ID where the device
is being detected and a word “added!!’ on the log box. If somehow those
things never showed up, check out the USB
cable connection, read again from the top of this post.
Step 7: Flash it!
Once all set and ready, hit he “START” button to begin flashing.
Do not touch anything that might interrupt the process to avoid any
fatal errors or failures, it may ruin your device if any interruption
occurs while already in flashing status.
It may only takes about 3 to 5 minutes, depends of your PC/laptop
speeds. A word “PASS” will display in Odin once it finishes. If somehow
you will not get the word “PASS” or just stuck in along time. Disconnect
the phone, remove battery, re-insert it, check the USB
connection, re-install the driver, disable Kies and any anti-virus. Set the phone in Download mode again, and repeat the whole procedure.
The phone will just automatically reboots if the firmware flashing
successfully completes. Just wait until it boots up on the “S” logo for a
while then into an android update screen. If it still shows boot logo
try rebooting and if it stays there, you need to wipe your phone.
