[Q] Cannot reset Nook Tablet
Recently my Nook Tablet 16Gb stopped opening ebooks. It is quite essential feature since I only use it to read books.
The story started ~2-3 years ago. I have bought Nook Tablet and wanted to get root access (to get some nice apps from android market). To get root access I used something like zergRush tutorial os similar. It worked fine until the B&N released new update 1.4.3. I have lost root access. Yet I was able to run already installed apps. It was totally fine with me: ebooks + a few apps from android market.
Yet as I said in the beginning, I could not open ebooks anymore. So I decided to erase & deregister device (and say goodbye to limited root). I clicked it and after Nook restarted the message "Please restart your device and try again...." showed up. After the second restart the message disappeared but Nook was not erased. The same data, the same issue.
Then I decided to google and try to "unbrick" (despite it is not really bricked). I made bootable microSD, and tried loading 1.4.2 factory recovery zip. Everything was fine, I even saw a green checkmark on a screen "Do NOT Turn Off Your Device Installing New Software....". Yet after I ejected microSD and Nook restarted, nothing changed. It was still the same system with exactly the same data.
Next thing that I have tried is to follow steps from github of succulent under acclaim_recovery_sdcard. The same story. After restart Nook always keeps running the same system.
I even formatted the following partitions in one time:
The same system after restart...
Tried to apply root for 1.4.3 and install different rom. The same system as before any manipulations.
How is it even possible?! What should I try next? Any ideas appreciated.
