NtxHwCfg


NtxHwCfg is a simple utility for dumping or comparing hardware configurations used by NTX. NTX is an OEM which manufactures Barnes & Nobel and Kobo eReaders. The utility is available for both Win32 and Android.

The configuration file itself is on the device in unpartioned space. You may make a copy of the configuration by:

dd if=/dev/block/mmcblk0 of=cfg skip=1024 count=1

You may write back a modified configuration by:

dd if=cfg of=/dev/block/mmcblk0 seek=1024

Warning: Note the difference between "skip" and "seek"! A bad configuration will break your device. You would need to disable the internal flash and boot up using a u-boot that ignores the NTX hardware configuration.
