# GCC-4241N External TSOP Recovery Observation

## Validated observation

The user reports that at least one GCC-4241N was successfully unbricked by
programming its TSOP48 flash externally with the available TSOP dump.

This validates the practical feasibility of external-programmer recovery for
that unit and dump.

## Not yet validated

This observation does **not** establish:

- that the failed unit was double-encrypted;
- that `XBOX_HITACHI_KEY` was used;
- that the historical XOR mask is correct;
- that the historical 32-bit bit-swap map is correct;
- the ordering of any encryption, XOR, bit-swap, byte-swap, or lane-swap stages;
- that the dump matches a known logical firmware image of the same revision.

Those transform claims remain pending Batch 06 comparison against the actual
TSOP48 dump and matched logical firmware evidence.
