"Make sure phone is off. Boot into download mode. To do so, hold down the Volume Down, Home and then the Power buttons together until a Warning!! message is displayed on the screen. Here, press Volume Up to enter download mode. A green Android and the text Downloading will be displayed on the screen.

Now, open Odin by clicking on the Odin3 v3.07.exe file in the Odin307 folder which you obtained after extracting Odin307.zip

In Odin, click on the PDA button, then select the VRALEC.bootchain.tar.md5 file that you downloaded.

Important Untick every option under the “Option” section (on the top left of Odin), except F. Reset Time. Check the screenshot below for reference.

Then, connect the phone to the computer with the USB cable and wait for Windows to finish installing drivers. Odin will say Added!! in the message box on the bottom left if the phone is detected successfully. If not, make sure the drivers are installed and also try using a different USB port – preferably a USB port on the back if using a desktop computer.

Click on Start to start flashing the VRALEC.bootchain.tar.md5 file on the phone.

Wait till flashing is complete and you get a PASS message in Odin. When that happens, disconnect the phone from the computer, but DON’T turn it off and let it stay in download mode. Also close Odin.

Reconnect your phone to the computer (while it is in download mode). Open Odin again.

This time, click the PDA button and select the BOOTLOADER_I535VRALF2_618049_REV09_user_low_ship.t ar.md5 file that you download

Also, again untick every option except F. Reset Time in Odin. Then, click on the Start button to start flashing the BOOTLOADER_I535VRALF2_618049_REV09_user_low_ship.t ar.md5 file on the phone.

When flashing is complete and you get a PASS message, disconnect the phone and close Odin. But keep the phone in download mode, don’t turn it off.

Open Odin again and also reconnect the phone to the computer.

Click the PDA file and select the stock.vzw_root66.tar file that you Downloaded

[Important] Select the following three options in Odin on the top left: Auto Reboot, F. Reset Time, Nand Erase All. Check the screenshot below for reference.

Click Start to start the flashing process. Once the flashing is complete and you get a PASS message, the phone will automatically reboot. Disconnect the phone from the computer.

The phone will still not boot up completely. Now, remove the battery on the phone, then re-insert it. Don’t turn it on.

Now, boot into recovery. To do so, press and hold the Volume Up + Home + Power buttons together till the screen turns on, then let the buttons go. The phone will boot into recovery in a few seconds. You will see a few error messages in recovery, which is normal.

In recovery, use the volume buttons to scroll up/down and the home button to select options.

Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete (this will NOT delete your personal files on the SD cards).

Select wipe cache, confirm, then wait for cache wipe to be completed.

Then, select reboot system now to reboot the phone.

The phone will now boot up properly into Android and is fixed, and you will be able to use it now."
