This board requires you to be registered and logged-in to view hidden content.

Make sure your device is fully charged.
Unpack contents to fresh SD card formatted FAT32
Ensure your device is fully OFF (not in standby), insert the card in device and power on.
"Loader" will appear on screen for a while then the device will boot up when the flash of patched firmware is complete.
Your device may reboot its self during the process just be patient.

Your SD card will have a new file named 154.bin this is a backup of the device's non-volatile memory region and may save your device later if needed,so keep a copy of it somewhere safe.

Thanks i guess it wasn't pulling up because i left the "B" in it . Also figured out i need RGN Tool.
