[Barnes & Noble Nook Tablet] RevenantOne:
Here are my thoughts on the Nook Tablet and my rooting process. I try to write to be as friendly as possible for the newbies to rooting devices. This is really just a reflection of my experience with the device and my rooting effort thus far .

If money is no issue, by all means go with the 16GB. But if you really want the best bang for the buck, go with the new 8GB version over the 16. The main difference is the RAM but since we are not talking about a true multitasking device, the extra RAM does little. Even if you root and hack and upgrade and tweak the hell out of it, you'll never really do more than one thing at a time on the device itself so 512MB is usually plenty. I have found that the Nook is the perfect companion device (for references and reading) to go with my netbook (which is the pefect portable productivity device) and my rooted android cell (universal connectivity device with tether hack). Those three things working in tandum mean that I can get online anytime, anywhere, and work comfortably. Now, if I can just find an Android phone that has a battery that lasts for more than 4 hours with the wi-fi/tethering/mobile hostpot turned on.

I have successfully used jichauan89's Root for Nook Tablet 8GB (w/ Android Market) root method number 1 (the SD image). Thank you jichauan89! It was easy and worked great the first time. His procedure...

Here was my specific procedure and thoughts.

Prior to the attempt. Make sure that the device has plenty of battery power or is plugged in the wall adapter. This is a good practice for all rooting/hacking attempts on these types of devices, including cell phones and media players. I backed up the data on my SD card by simply copying all the files to a folder on my netbook's desktop.

Used Sandisk 8GB microSDHC card I had in my old Samsung Captivate. I used the SC card adapter it came with orginally to insert it into the built in SD Card reader in my Windows XP netbook.

Downloaded the SD card image from exactly where jichauan89 described.

Used Win32DiskImage.exe to format and write the image to the SD card. Worked without error. I used the safely remove hardware option in Windows to disconnect the hardware before removing the card from the reader.

Powered off the Nook Tablet 8GB.

Inserted the freshly formatted and imaged SD card into the Nook.

Held the power in until it powered on.

Saw a cardboard box. It reminded me of Amazon's frustration-free packaging.

Waited.

Saw the "Read Forever" Nook logo.

Waited exactly 3 minutes.

Held the power button in until the powered off.

Removed the SD card and set it aside. It's mission is complete.

Held the power button in until it powered on.

Routine booting began.

Upon boot completion, I clicked the n button and selected "search". I searched for "market". It found the Android Market. Don't look for "play". The hack itself uses an old version of the market that will upgrade itself to Google Play after you run it (as long as you are connected to WiFi).

At this point, your device is rooted successfully. Anything else you do is really just gravy. I suggest doing the NT Hidden Settings to allow sideloading and I also suggesting doing the hack to stop updates so that you get to keep all your hard (not really) rooting working in tact if and when B&N rolls out 1.4.3 of the Nook's firmware. Here are the additional steps that I took, again, this is all thanks to jichauan89's simple instructions and the feedback given in his thread. Also note, when I did have issues, I kept reading the thread rather than jumping the gun and posting my own questions. All the answers were already there...

I installed NT Hidden Settings from the market.

I immediately used the hack to allow 3rd party apps. There was some confusion and error here. I ran it a few times and it didn't appear to do anything, but then I pressed the n button once and a super user screen appeared asking me to give NT Hidden Settings rights, which I allowed. I tried the 3rd party hack a few more times to no avail. I rebooted the device and tried and tried and it wasn't working and the check mark on the previous screen for allowing Uknown Sources simply seemed to uncheck itself. I was watching the new episode of South Park on TV and at one point I reran the hack for about the 300th time it felt, a message came up that the app had been given SU rights, and I moved my attention to South Park for several minutes. When my eyes came back to the Nook, I checked the Unknown sources setting again, and it was checked, all by itslef. Lesson, I believe that the 3rd party app hack takes a few minutes to actually do anything after it is granted SU rights but doesn't give any notification that it is successful (or I missed it while grandma was trying to make Butters eat a urinal cake). I believe the app checks the Unknown Sources box itself as a part of its script and all the other times I had run the hack, I was just being impatient. After several reboots, the check now stays.

I then ran the NT Hidden Settings hack to keep updates from being installed. I was notified almost immediately that the installation was successful.

I then installed Go Launcher and HomeCatcher. I got Homecatcher from an XDA forum post and not from the Android Market. After running HomeCatcher, I clicked the n button and selected home and I was prompted to choose between a little andorid guy and the stock nook launcher. I made sure that put a check in the box to make this decision default (which i kind of wish i didn't, but it should be easily undone) and then selected the Andorid icon. Now whenever I select home, it goes to the Go Launcher app, awesome.

I also immediately installed File Expert and Titanium Backup and everything seems to work perfectly.

I then installed the Amazon App Market from Amazon.com in the Nook's stock browser. Every app from their seems to fail and says "SD card required" or some such thing. I am assuming that if I put the SD card back in everthing would work fine, but I'm not sure why this is an issue. Shouldn't it be able to use the Nook Tablet's internal memory? I'll keep testing.

The only thing I'm thinking about now is that I want to find the fastest way to switch back and forth between the stock B&N launcher and Go Launcher. I like B&N's ecosystem, even though it is limited, but I enjoy the advantages I get from walking in the store and getting to read books and even though the user interface of their digital store is one of the dumbest things I have ever seen, I find myself wanting to us it because I support Barnes & Noble a lot and wish them the best. I do, however, wish they would listen to all of us who are *****ing about their Market's limitations and ridiculous pricing and either treat the device more like a tablet like the name implies. But I'm preaching to the choir, right?
