3. **Start SSH** on the Pogoplug

   The Pogoplug's stock busybox-based Linux distro ships with the dropbear SSH daemon installed, but it isn't running by default.  Luckily, you can start it by sending an HTTP POST to the Pogoplug's web interface.
   
   If your local network supports resolving the Pogoplug's default hostname of `PogoplugMobile`, you can run this curl command:
   
   `curl -k "https://root:ceadmin@PogoplugMobile/sqdiag/HBPlug?action=command&command=dropbear%20start"`
   
   Otherwise, you'll have to stick it's IP address in there, e.g.:
   
   `curl -k "https://root:[email protected]/sqdiag/HBPlug?action=command&command=dropbear%20start"`
   
   The curl command will spit out a bunch of HTML in your terminal.  That means it worked.
   
4. **SSH into the Pogoplug**

   Again, if you can resolve the Pogoplug's default hostname, run this:
   
   `ssh root@PogoplugMobile`
   
   Otherwise, use it's IP address, e.g.:

   `ssh [email protected]`
   
   The stock root password is `ceadmin`.
   
5. **Download and run the script**

   Here's what the script does (have a look: http://git.io/vCtIl):
   * Prompt you to verify the Pogoplug's MAC address
     * (it is printed on a sticker on the underside of your Pogoplug)
   * Download some flash utility binaries
   * Download some uboot binary blobs
   * Burn uboot into flash
     * (it will prompt you for permission to do this)
   * Burn uboot's default settings into flash
     * (it will prompt you for permission to do this)
   * Tweak a bunch of firmware settings in the flash
   * `poweroff` the Pogoplug
     * (it will prompt you for permission to do this)

**After rebooting, your Pogoplug will be able to do the following:**
* Boot the stock Pogoplug OS
  * (just disconnect any USB drive and SD card and turn it on)
* Boot your Linux distro of choice from USB or SD card
  * (uboot expects a bootable ext3 partition labelled 'rootfs')

**Note:** If you are rebooting back into the stock Pogoplug Linux install, don't freak out when you can't ssh into it anymore.  You have to run that `curl` command again every time it boots into its stock OS.

**Note:** If you are running this script on several Pogoplugs and get tired of answering all of the prompts, you can instead tell the script to assume yes to all prompts via `ash uboot.sh -y`.

## Credits

This script is based on the instructions in Qui's blog post: http://blog.qnology.com/2014/07/hacking-pogoplug-v4-series-4-and-mobile.html

Qui's work was in turn based on work from the crew at the doozan forums: http://forum.doozan.com/

## FAQ

**Q: Why aren't you using a github URL in the above instructions?**

A: It turns out the version of wget (busybox) which ships with the Pogoplug doesn't do HTTPS at all, and github now forces all HTTP traffic onto HTTPS, which causes wget to fail like so:

**Q: I'd like to verify the contents of the script before running it.**

A: Run this:

## Changelog
