Writing in sector trailers

Hi,

I would like to copy card (A) data to another (B), but leave secret keys of (B) card just upload (A) card data.

HF MF DUMP1K / RESTORE1K copy secret keys so its not what I need

So I try HF MF WRBL <block number> <key A/B> <key (12 hex symbols)> <block data (32 hex symbols)> but it's only possible to write first block, how to write other 3 blocks of sector?

Re: Writing in sector trailers

block number = sector number * 4 + block num(0-3)

so...

sector 1 block 1 ===> blocknum = 5
