Visual NAND Reconstructor 5.1
Dear Users,
We are glad to introduce a new update of VNR 5.1!
We have been focused on the very specific feature of Sandisk and Phison controllers that is widely used these days – Block Rotation.
Flash controllers utilize this feature in microSD and SD cards mostly. We have developed special set of features and elements in VNR to handle all known modifications of this operation.
Here’s full list of features:
Block Rotation
The new element has several modes depending on the device brand as well as type of rotation (the article on the usage is being added to Help Center).
In case of multiple dumps, the block rotation element must be connected to each one.
Normally not all blocks have rotation, so the effect of transformation may not be significant for a portion of data, however in some cases data has vast corruption unless rotation is removed.
Below are several examples.
Phison – before block rotation
Phison – after block rotation
Sandisk – before block rotation
Sandisk – after block rotation
