[Nook Touch General] Crispy3000:
Suddenly increase of the people trying to root their devices recently.

Something goes wrong and either they have no backup or its damaged and then they have a lot of trouble.

So I'd thought a list a couple of things that you should do BEFORE you try to do anything else to your Nook Simple Touch or Nook Simple Touch Glow aka NST/NSTG

Now I strongly suggest making two backups in different manners detailed below. I personally do this before I even use my NST for first time.

NookManager:

Nookmanager has a great backup tool however it does save it directly onto the sdcard which if is not big enough or has other errors or you simply end up deleting by accident.

Pros: Convenient backup and restore. No need for PC. ADB over wireless to copy backup.

Cons: Must remember to copy off sdcard, at mercy of sdcard failing.

Noogie:

Noogie allows the NST/NSTG partitions to be completely accessible by a PC over a usb cable.

You then use a tool on the PC to backup all the partitions to a file.

Pros: Your backup is stored independent of your sdcard. A bit more verbose by default.

Cons: If your usb cable is dodgy or usb bus errors can be introduced.

Both systems have good points and bad points doing both means if one is not quite right you have an alternative. Its worth doing both.

A complete image of a NST/NSTG is around 1.86GB in size however after compression should be around 280MB.

Now to the details.

I would do Noogie first as you can then use the same sdcard to stick nookmanager on that you may want to do the root with (after backing up correctly).

Some of my nook's usb cables were charge only ones (very handy) so if cable is thin with too cores and long use a different cable.

I would try and avoid using class 10 sdcards for this process.

Noogie

###########

If you use windows use this guide

The same method you stick noogie img onto sdcard you can use to stick nookmanager as well.

After the backup check your event viewer [Start->settings->Control Panel->Administration Tools->Event Viewer->System].

Look for any error Red or yellow warning about disks.

Windows does not pop up something when your having serious disk errors (even to their latest version!)

Remember to "safety remove the hardware" before unplugging the NST.

You will end up with a 1.86GB image file I would suggest compressing it using rar/zip to get to a manageable size plus add some CRC checking.

If you use Linux use this one.

If you linux newbie be very very very careful with the dd command. Its very powerful and a simple typo can ruin your computer.

Make sure nothing is mounted during the process.

Run dmesg or sudo tail /var/log/kern.log to see if any usb or disk errors.

NookManager

##############

Read the Guide

You can use winimage mention in noogie guide to stick Nookmanager on a sdcard too.

When booting off Nookmanager say no to wifi, Rescue->Backup, Use rest of space on SD card, create backup.

Obviously make sure your device is well charged and choose a big enough sd card to hold the backup. Its about 280MB compressed.

Once backup is complete we want to get it onto our PC or something other than a single sdcard which are prone to sudden failure.

Nookmanager has stored the backup on a second partition on the sdcard.

Windows does not like mounting second partitions on removable devices by default so we can't easily be able to access it.

If you can either enable wireless and usb adb to copy which I won't go into now or connect your nook via usb while running nookmanager and it will appear as a mass storage device.

You are looking for a file called "backup.full.gz". Copy that as well as its md5. Make sure you check the size is around 280ishMB.

If you have already connect the stock nook over usb or used noogie over usb to your PC sometimes it will get confused and the drives won't appear in windows explorer.

This is windows getting confused. If you click on the safetly remove device icon you will see two drive letters are assigned its just explorer that can't access them. Easy fix is to reboot. If your like me and dozens of web browsing windows open and regard rebooting as something the power company forces on me few times a year you can do this to access.

Start->settings->Control Panel->Administration Tools->Computer Management->Disk Manager.

You will see the drive letters for your nook there. Right click (don't click format or delete!) and chose open. Explorer will now happily open a window with your drive contents.

Again as with Noogie check your event viewer system for any errors. (make sure hit F5 for refresh)

On linux you can mount the second partition no trouble so either remove sdcard and stick in a reader or use nook via usb cable. Mount and copy. Check size of file. I am sure if using linux and have mastered dd you know how.

So now you should have two full backups using different methods.

Now go forth and root, tinker and learn about with your NST/NSTG to your hearts content knowing you can safely recover.

Personally I like Version 1.2.X Nookmanager as a root method but I was also recommend if you have more than one NST trying out all of kuskro's hardwork on 1.1.X and excellent guides starting here (never tried on NSTG however)

Getting your SDcard back to normal

###################################

After rooting/backing up if you want to put your sdcard back to normal for storage you can't just simply format as the card has been repartitioned.

Easiest tool I have found for doing this is HP USB Disk Storage Format Tool which should be here I think.

Simple to use just select sdcard and hit format. It will automatically repartition and format to the maximum size of your card.
