I have put together some previous articles on upgrading the firmware on your Linksys WRT600N wireless router using various versions of DD-WRT. One thing I have not included in the articles is the specific DD-WRT download location for the firmware branch that I prefer which is called BrainSlayer. So below is a brief explanation of DD-WRT FTP structure where the WRT600N firmware is located.

How To Unjailbreak GreenPoison, Remove GreenPois0n From Your iPhone

Insights13 Comments

I had been wanting to jailbreak my iPhone 4 for quite awhile but since I had upgraded to Apple iOS release 4.2.1 there was not an untethered jailbreak available at the time and since I typically turn my iPhone completely off I didn’t want to deal with the untethered jailbreak. So needless to say when GreenPois0n rc5 was released I was pretty excited. GreenPois0n rc5 made it extremely easy to jailbreak iPhone’s running iOS 4.2.1. After running it for around a month now though I noticed that I really don’t install enough applications outside of what is available via the iTunes App Store to warrant the jailbreak and especially because I have personally noticed that with my iPhone jailbroken it had slowed down a bit. Not only had it slowed down but my battery appeared to be draining much quicker which I assume was from more processes running. I made the decision a couple days ago to roll back to the stock iPhone 4.2.1 firmware to see if my phone started running more efficiently. Below are instructions for rolling back the GreenPois0n firmware on an iPhone 4 to the Apple iOS 4.2.1 firmware release.

Get Dell Wireless 350 Bluetooth Module Working With Backtrack, Dell Bluetooth 350 With Ubuntu

InsightsLeave a comment

Getting this module working is not very much fun if you are on a single boot system with Backtrack or Ubuntu installed however it is much easier if you are on a dual boot system that happens to also boot into Windows XP. I personally ran into the issue of the Dell Wireless 350 Bluetooth Module working with Backtrack on a development laptop that luckily didn’t have much data on it because to resolve the problem you need to install Windows XP, run a executable within XP from Dell to upgrade the firmware on the Dell Bluetooth 350 Module, and then reinstall Backtrack. Below is more information about how to get the Dell 350 Bluetooth Module working in Ubuntu or Backtrack Linux.

I recently ordered one of the newer Asus routers just to stay up on the wifi world and I decided on the RT-N16. I normally like open-wrt firmware however its still listed as a work in progress for this router. This left me with 2 options, Tomato firmware and DD-WRT firmware. For the first run I decided on DD-WRT. Below I will outline the relatively simply steps to get up and running with dd-wrt on the n16
