BRICK WARNING!!!
You have to make sure the correct flsh.hex file is on the flash drive and in the far right USB slot!

4.82 flsh.hex MD5: 8e156c99101bf36ec3edb832982ae46d

=================================================================================================================
PLEASE READ FIRST:
It's essential not to flood the browser memory with junk before running the exploit.
The reason for this is that due to javascript core memory usage limitations
we are scanning several times a small range of browser memory (a few Mb) to find some essential data in RAM,
if the memory is flooded then the range to scan becomes much larger &
the probabilities that our data is found in the smaller range decrease dramatically....

So in short, never use the browser or set a homepage you cancel before running the exploit!
If you need to, set the homepage to 'blank', close the browser then reopen it to start the flash writer.

Usage Tips:
1) Try using a LAN connection or a solid WiFi connection during exploitation. A weak signal can cause problems.
2) If the exploit takes more than 5 minutes to work, reload page, browser, or restart console and try again.
3) If you are using a LAN connection and experience network issues, make sure all cables to router are in working order.
