Today I restored 5th key and install 3.52 Sony fw. (when 5th key being not patched - the installer returned an alert message).

But when I returned to 3.52M33-4 cfw by restoring nand dump with pandora unbricker without restoring ID Storage keys - I got brick.

When I restore nand dump with restoring ID Storage keys - my 3.52M33-4 been success restored.

And we got for TA82 mother board:
unpatched 5th key - use only 2.71-3.52 official fw.
patched 5th key - use 1.50, 2.71-3.11 official fw + custom.
