Thanks CodeKipper for the tips. Dumping from 0x43000000 offset (that's what script-extractor tool does), I get just half-meaningful headers:
$ hexdump -C script_extractor.out | head 00000000 49 00 00 00 00 00 00 00 01 00 00 00 02 00 00 00 |I...............| 00000010 70 72 6f 64 75 63 74 00 00 00 00 00 00 00 00 00 |product.........| 00000020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000030 02 00 00 00 de 02 00 00 70 6c 61 74 66 6f 72 6d |........platform| 00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000050 00 00 00 00 00 00 00 00 01 00 00 00 f2 02 00 00 |................| 00000060 74 61 72 67 65 74 00 00 00 00 00 00 00 00 00 00 |target..........| 00000070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000080 02 00 00 00 fc 02 00 00 70 6f 77 65 72 5f 73 70 |........power_sp| 00000090 6c 79 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |ly..............| I mean, I can read section headers (product, platform, etc), but all are empty... I'll try to find some useful image.
