can any of you help me with a dump of the files in the NV (NAND). I played a bit with them

You need Qualcomm PST 2.7 Build 264:
1. Put your ICON 225 into USB
2. Install Qualcomm PST 2.7
3. Click Start - Programs - QPST - Software Download
4. Select tab "Backup" and click Start (qpst will save NV items as *.qcn file, for example nvt.qcn)
5. Close Software download
After that could you upload the file somewhere and share the link?
Thank you in advance
