NOOK GLOWLIGHT PLUS NOT RUN

[sbwtxj]

Hi ,
I accidentally deleted the core system files, such as nookbook.apk and nook.com.apk files , the device operation is not normal.

How to get the two files NOOKBOOK.APK AND NOOK.COM.APK ?
OR How to restore system firmware by other methods?

Using 7 times, of course, interrupt method to restore the factory Settings,
but the system doesn't run properly.

thanks

You can find latest update from http://www.nook.com/services/cms/doc...ifest_rel.json
Currently, it's http://su.barnesandnoble.com/nook/pi....14/update.zip

Nook will automatically detect update.zip and update if you put it on internal storage of nook.

===========================>
I download the update file,but my device display the only U disk, not include NOOK directory.
After the device starts, the black screen only shows.
I thinks the device no core file, such as nookbook.apk and nook.com.apk files.

http://su.barnesandnoble.com/nook/pi....1-release.apk File not found.

So can you help me how to backup the all system with good NGP, then how to rebuild the system with the backup?
thank,
alan

Hi,

I didn't carefully deleted the Nool.com.apk and Nookbook.apk files on the core file list with USB debugging.
The device did not display the home interface.
so i did the hard reset factory , but after this done, the system is playing boot animation continuously with three dots , until the power is empty and not performance the hard reset.

Now i don't know how to do.
