Visual NAND Reconstructor 3.9 update
We are glad to release a 3.9 update for both products VNR and eMMC-NAND Reconstructor.
Here’s what we added
The new chips have been added to database
VISUAL NAND RECONSTRUCTOR
New automated tool for Bad Column analysis and removal.
Thanks to our new binary statistical analysis platform that works at the heart of VNR we have been able to automate one of the most time consuming routines in the chip-off data recovery workflow which is a Bad Column removal. We have created special presets for the most popular controller vendors that helps to identify and remove all bad columns at once using simple filters. It not only works on typical cases with visible bad columns (white/dark contaminated columns) but also in cases when bad columns are XOR’d. The precision of the algorithm is high but in case of false positives there’s a very flexible set of tools that will help to fix it in semi-automatic mode. We fused the new features into existing interface, so the transition to new mode is smooth and easy, while old mode may also be used.
BCH ECC codeword analyzer now supports brute force of new ECC types (new bit rotations), e.g. SM3259, SM3271 and other families of controllers
XOR element can now be adjusted to any existing or custom area (SA, ECC, etc)
File system corruption analysis mode has been significantly improved with ability to point to the problematic place in block translation of Markers Table. In case if part of data is shifted/corrupted and the reason of that is missing/doubled/wrong block it is now easy to locate the problem with precision of several blocks.
“Paste till the end” option is added to page structure viewer
The file carver now has completely revamped interface with much simplified workflow and file selection /extraction.
Results of carving now categorized depending on file type and displayed in file system viewer-like mode
New option to ReRead memory chip by ECC map of selected files.
DOC/XLS office document carving is now supported in addition to existing formats
New mode of Exif metadata parsing for carved JPEG files (metadata of picture such as camera mode, timestamps, etc)
New monolithic chip pinouts
New NAND chips
several more configurations have been adjusted
New XOR keys
