Onyx Boox M92 MFGTOOL Problem

I've problem with my M92. After the battery was disconnected, the e-reader came in recovery mode "NS BLACK CODEX". I can't flash it with MFG TOOL, becouse it freeze at "Getting device info."
I looked into the file (ucl.xml) and I know now it freeze at commend:
" <CMD type="push" body="mknod block,mmcblk0,/dev/mmcblk0,block"/>
<CMD type="push" body="send" file="fdisk-u.input">Sending fdisk input</CMD>
<CMD type="push" body="$ fdisk /dev/mmcblk0 < $FILE">Partitioning SD card</CMD>
<CMD type="push" body="mknod block/mmcblk0,mmcblk0p1,/dev/mmcblk0p1,block"/>
<CMD type="push" body="mknod block/mmcblk0,mmcblk0p2,/dev/mmcblk0p2,block"/>
<CMD type="push" body="mknod block/mmcblk0,mmcblk0p3,/dev/mmcblk0p3,block"/>"
MFG TOOL can't make node for mmc memory, becouse first commend is:
"mknod block,mmcblk0,/dev/mmcblk0,block"

This is IMX507. Can anyone help me with that?
Everything was OK before battery was disconnected.
I don't believe that the memory is burned.

Maybe there is another tool like "AdvancedToolKit" that support IMX507 and make this device usefull.
