sample checksum table, 17 blocks, last 5 have checksum disabled:

start_addr end_addr cksum_val
00008000 0013F4FF 176EBB28
000FAE00 000FB8FF D9F0DD89
000FB900 000FC3FF 2423D83B
000FC400 000FCEFF F0CA38E8

000FDA00 000FE4FF 5AA5A81A
000FE500 000FEFFF 5AA5A81A
0013C300 0013CCFF 9CA358D7
0013CD00 0013D6FF E509C9A9
0013D700 0013E0FF 720C6238
0013E100 0013EAFF 5AA5A7DA
0013EB00 0013F4FF 5AA5A7DA
00000000 00000000 5AA5A55A
00000000 00000000 5AA5A55A
00000000 00000000 5AA5A55A
00000000 00000000 5AA5A55A
00000000 00000000 5AA5A55A

the version is block 0x0013F5CC-0x0013F5CF which is yymmddnn where nn is the number of rom saved for the date. just replace that with FFFFFFFF

Update: the BRZ/FRZ rom has another checksum table with 2 extra checksum blocks. The checksum fix has been made to RR but hasn't been released yet (check this update date) so you should use EcuFlash for checksum correction.
