TingedAce released a new version of XNand Healer GUI - an app that started off as an uncrippling tool but now morphed into a general purpose NAND dumping tool that should really aid the first part of the JTAG'ing process.

What's new/fixed:
- Much improved user interface including progress bars during NAND analysis
- Ability to cancel NAND analysis
- One-click bad block remapping
- Added dialog to let you choose how much of the NAND to dump just before reading
