Visual NAND Reconstructor 3.7 update

Dear users,

We are glad to introduce VNR 3.7 update with a new powerful features!
The greatest enhancement of this version is a new XOR analyzer tool that helps to autodetect XOR key fast and with a very high precision! Moreover we have significantly improved precision of ECC auto-detection and added many more improvements.
Among them are:

• New XOR analyzer mode

• ECC autodetection has got a new level of precision with automatic logging into a file

• MD5/SHA1 hashing for forensic users (works when saving image or anywhere you want in the workspace)

• New Read Retry algorithms (especially long waited AD3A180300 and many others)

• Pinout analyzer interface and functionality has been improved

• Many other minor improvements and bug fixes such as: multiple selection mode dialog, double click on Markers table to open, ECC window improvements, Premium Support status window, etc.

In XOR analyzer it’s possible to check each XOR key against every block of the dump (on the left side). Validation by current block will test all filtered keys against one currently selected block. Auto validation will do the same with key probability recalculation as you navigate across the dump jumping from block to block. We recommend to start validation on the very top blocks. If validation does’t bring positive results try to change bock size to 1/2 or 1/4 (1/6 in case if your NAND has WL protocol) and run auto-detection again.

The “Source” tab shows bitmap of current block, “Key” tab shows currently selected key and “Result” shows Source + Key (XOR’d). When one or several possible keys have high probability simply mark check boxes,   press “Apply key” button to move them into workspace for further analysis.

When scrolling the keys they automatically adjusted to the page structure. If you need to to look at the keys in original shape (as a catalog) simply press “XOR key browser mode” check box.

In order to extract XOR key from the dump in case of unsupported device check the top blocks in the left table that potentially have a key, select one or multiple blocks (mark check boxes) and press Extract current block / Extract selected blocks.
