[Q] How to restore to stock using boot.img & recovery.img - Barnes & Noble Nook Tablet

Hi
Trying to root my table tand get it to work, I have not succeeded something operational yet. I have made a root & CWD sd card, and in the process had backed up my tablet. I copied thgis backup to my PC as I had to try different things with the sd card.
So now I d like to restore (to start afresh) but... I google it around, and dont find any procedure!?
I am sure it is known... and am dummy... but can't invent neither.
I need use those files, because I still can't read .apks and try the apk based nook restore.
How should I go?
Your help appreciated
Thanks, Agnes

Restore method did not work....²
I have found my 3 neurons and realized I could just re do a CWD sd card, do a backup, and then take the card to my PC and add the other backup aside there (they are orgnaized by folders and date)
Then back to the tablet, go CWD / restore... but I only get a MD5 error and it does not want. Same with advanced restore.
I finally found this very simple method from Adam to restore to 1.4.0
http://forum.xda-developers.com/showthread.php?t=1402190
It semt it worked, but then when it starts again... I get the same broken rooted / whatever I have now .

Is your device 16GB or 8GB model? depending on that i can tell you what to do.
16GB model has more development and some modified stock ROMs , i even made 1 of them check here:

Veronica,
You wouldn't happen to have an un-modified stock ROM would you?

You want a sotck stock unrooted one? yet you need to reply me if your device is 8GB or 16GB model.

Yeah, an unrooted unmodified stick would be great. I've got a 16gb model.
Thanks.

16Gb device now messed uo....
Hi Veronica, thanks for the reply. I am deseprately in need of expert advice here, instead of guessing and trying...
I have a 16 GB Nook Tablet, that was bought with 1.4.0.
I now seriously again need to make a restore, as I did some bad mismanipulation and my tablet is now out of order:-(
One of my best chance I guess would be use one of the backups I have (I have several copied on my HD), but after I formatted and wrote on my SD card several times (is this the reason?), now when I try restore, I have this MD5 error.
I hope I would not run into other problems, as it seems my prop.build may have changed in the process....!
May I ask you to have a look what I did, and then confirm it would be wise try the restore you provided in the thread?
The history what I did:
- I initially had a 1.4.0 with some tweaks to sideload apps, and could no more sideload with 1.4.2 of course (and that is all I need: be able get Kindle, Le Monde, and few other apps!). I understood I had to root and was ready to try get CM7 on my internal drive, and tried a few things (Rooting with Indirect's method, ...), and could not get it to work, until I got very close:
- I restored 1.4.0 using this thread restore 1.4.0 from Adam Outler. It worked fine and apparently erased some of the problems I had that were previously preventing me to move with rooting etc.
- Then I used Albert Wertz's Backup of a rooted 1.4.0. It worked. It seems it had already OTA bloked (displaying version 9.9.9 or so)
- Then I was to install CM7 using this tutorial from ebook-reader, based on this Celtic XDA thread ("team B") (choosing the internal method) , and used the CWM flasher apk. That is where somewhere I did a mistake: after backing up and erasing all data, I somehow stupidly rebooted and got in trouble, and restored the old B&N I don't know how.
- Willing to go back to stage 1, I tried using the 1.4.0 basic restore from Adam Outler, but that did not work anymore, like if my build.prop had been changed in the process (where?)
It said "assert.failed: getprop ("ro.product.device" = blaze" or something alike.
- Then I got a long powercut (am in Africa) and some sleep
- The worse is, the NOOK does not boot and work anymore at all, it is stuck on "read forever" screen
- The curse is, I cant use other restores I have, it says MD5 mismatch
- I also can't use simple root procedures (with CWM and installing zips), as my basic system seems corrupted.
I guess a proper restore may work if I manage to do it, but I wonder what happened with my prop.build and why it was mentionned up there (was it changed in some of the process) - and whether it will create more trouble.
Your advice will be very precious!
Thanks, Agnes

Thanks for post the whole history of what you've done 'cause pfff that saves a lot of time.
Now in this part "after backing up and erasing all data, I somehow stupidly rebooted and got in trouble"
1. Did you get to flash CM7 succesfully
2. When you mention you backed up means you backed up CM7?
3. when you mention erasing all data you mean only wipe data (factory reset) or did you wiped maybe formatted anything else?
4. What method did you use to format your sdcard
Edit: i have a MIUI backup that i made for a guy that could not install it with the other way (install .zip) of the same ROM. So at list try it for now to see what happens, if it works then go ahead and flash back the ROM you want, and always make sure to check the md5 of what you download.
http://minus.com/mwIltnw1I/4f - NT_MIUI_Tweaks_backup.zip | md5: 3518f9a3289ca6e97b569777873b899b
* Uncompress the .zip and put the folder (do not change the name of the folder) in your sdcard and flash in CWM >> backup and restore >> restore

Thanks Veronica. Here is as much as I remember:
1. Did you get to flash CM7 succesfully?
No. While following the procedure, I did some mistake after backing up and before even trying to installing CM7. I did not realize I was in CWM within my existing rooted 1.4.0 (using the .apk), so somewhere I wiped and rebooted... to realize I was rebooting into nothing! Or actually into the original 1.4.0 B&N. And then I did some attempts to go back step by step (like restoring that 1.4.0 from Adam then the rooted 1.4.0 from Albert) and somehow went into more troubles.
2. When you mention you backed up means you backed up CM7?
No, since I did not go so far as to install CM7.
I have a backup of my initial (tweaked) 1.4.2 system, then one of Albert rooted 1.4.0 (not mine), then another one of a Nook normal OS that worked (not sure, I think 1.4.2) at some point later.
These backups were OK, I used at some point, I don't understand why then I got this MD5 errors.
3. when you mention erasing all data you mean only wipe data (factory reset) or did you wiped maybe formatted anything else?
I used the command within CWM, both to wipe data and cache
4. What method did you use to format your sdcard
I usually use Acronis Disk Manager, a quite powerful programme to change partitions on disks and also handle formatting. When I really want to make sure, I first use HP USB formatting tool, and then sometimes check on Acronis to get the partitions I want. I am not sure in what order I did that time, but was not using partitionning in fact.
I will redo it all again as I wonder if it is not a mistake on the disk that lets it misread the MD5, as I think my backups were fine.
I don't undestand:
- why my MD5 are wrong, and is it something I can fix by properly reformatting mys disks
- what is this story with "assert.failed: getprop ("ro.product.device" = blaze" and where I may have changed the build.prop. Is it somehting that will bother me further or should push me into one direction rather than another.
I will try your MUI backup. (What means MUI?). (It may take ma a day or 2 to download this through Lesotho poor internet :-(
Thanks and wil tell you what happens!

Try formatting your sdcard again, i recommend SDFormatter. Sometimes sdcard can be the cause of many weird errors and issues.
Then copy back one of your backups within clockworkmod >> backup folder
If no go with that then try the following.
* First you need adb working
Here is a tutorial i made about it: http://forum.xda-developers.com/showpost.php?p=22049356&postcount=1
* Plug your NT to your PC using USB cable
* Download the file attached which is 1.4.0 stock build.prop, uncompress it, put it in the same folder adb is located and push it using adb while in CWM
> cd path-of-adb-tools
> adb devices
(verify that you get a code with numbers and letters)
> adb remount
(if this command does not work for you then please mount /system manually from mount&storage > Mount /system in CWM)
> adb push build.prop /system
* Unplug cable
* Try Adams acclaim_update.zip again ( preferably with nothing else in your sdcard only that .zip
* Report back

OK I now was finally able to download the files.
- I guess I'll try first what you suggested with the MIUI backup after a proper reformat.
(I am just not sure which CWD file to use, as many dont leave any space on the card to put backups....)
- Then the ADB method if the 1st one does not work.
Though, part of the ADB tutorial is this "ADB root hijack" where they say you must already be rooted - that is not my case....
I'll try do tomorrow... and report! So glad to have your help here.

Successfully restored MIUI backup... what next?
YES!
@Veronica, I have been able to restore your MIUI backup!
I am not sure what it is... it looks like for a phone.... but it seems Market is working YEAH! 1st time on this Nook!!!!
Veronica you are a queen !!!
May I ask you what should be my next step now?
As a reminder, I basically want to get here Kindle (because I bought this Nook for Xmas for my Mozambican husband without realizing B&N does not have any Portuguese books, while Amazon does) and a few more apps I like. So this would do! But I d like make sure:
- my system is more or less stable
- I don't get messed up with more OTA updates
So I wonder:
- is this system recommendable? This is rooted, right? Should I prefer Launcher or Zeam Launcher here?
- should I rather use another system? Go into CM7?
Since I dont have even any Nook here behind, I am afraid of more troubles following the normal procedure, should I?
- Do I need at all to set the normal version of Nook behind (like I could use with the Nook button app) - in fact, I don't really care...

HELP PLEASE!!!! Nook 8Gb!
Can somebody help me? I bricked my nook tablet 8Gb!!
This is the whole story:
1) Rooted my NT
2) Used this apk to install CWM
http://forum.xda-developers.com/showthread.php?t=1458630
3) Tried to flash CyanogenMod 7 ROM but while it was flashing the tablet blacked out and rebooted
4) Now the tablet is stuck at the READ FOREVER screen
5) I can boot in CWM holding power+N button, but it can't flash anything, it freezes anytime I try to flash something.
6) I followed these 2 guides to unbrick my NT but they didn't work

@JohnDorian, Seems you got very similar problem to mine...!
It seems we got the same problem trying to do the same thing... So the same solution may work? (the only difference beeing I have not tried the unbrick mehods you did)
What I just did with Veronica's guidance, and worked for me:
- I created a 50MB sd card to boot into CWD, using this
- booted into CWM with it
- copied onto another SD card the MIUI backup Veronica provided earlier in this thread:
http://minus.com/mwIltnw1I/4f - NT_MIUI_Tweaks_backup.zip | md5: 3518f9a3289ca6e97b569777873b899b
- inserted it and did restore. It just worked and provided something that seems acceptable!
And at least, next steps may be possible...
I hope it works with you too!

Thank you for your answer!
Will this work also with my 8Gb NT?

Hello im glad to see you're back, about launchers, addons & apps it all depends of your likes.
What i gave you is MIUI ROM (operative system) without major modification (as-is) and yes it has zeam launcher but all can be modified.
I'm personally not a fan of gingerbread CM7 because i really like the eye candy of MIUI and even stock (which the buttons and menus are very similar to MIUI) so i use MIUI.
About stock i didn't mind using it even though i don't use B&N application and buy books from them buy i enjoyed the eye candy (interface/GUI), now that @cobrato released MIUI i immediately switched to that as im a huge fan of MIUI.
I have always used GO launcher as my main launcher but now im starting to use ADB in MIUI because it manages better the grid feature.
All systems you're going to find already come rooted which is standard and is the feature #1 of custom and stock ROMs, without root there is no fun. If you're in this community is because eather you have a rooted device or you came to learn how to root it and other stuffs.
If you like B&N stock ROM but don't use their apps and services you can bypass the registration and forget about the OTA updates, you can also apply on top of that the OTA block with titanium backup if you want to make sure. That is the methods i used and never ever had a problem. I also recommend you that when you flash a stock ROM do the whole procedure of OTA block and don't guess is already blocked, nothing better than do it yourself manually.
If you decide you want to make use of B&N services then you can eather go back to stock for a complete B&N experience or just install their app from the market if you're on CM7, CM9 or MIUI that is, nothing fancy but it does the job.
I have mentioned days ago that i was going to make a thread for MIUI users with how-tos and info about set it up but i've got very busy with many bricked devices around lol, but i eventually will do.

I don't have a 8GB nook tablet to upload a backup of stock ROM and actually is very important to have nobody has been nice to upload it and post it in development section. Anyway let me give you the link of the official update to see if that helps, i was checking yesterday and they provide one for both i think there is not a separate section for the 8GB model so i assume that update is for both models containing 1.4.2
