Unbrick NAND PS3 with Progskeet

I installed OtherOs with faulty dtbImage.ps3.bin. I didn't check dtbImage.ps3.bin file's MD5 after download and now my ps3 is bricked after install the OtherOS because of dtbImage.ps3.bin. So I'm planing to buy a new progskeet 1.1 with solderless clip. But I haven't any clue how to unbrick it. Or can it be done? What is dtbImage.ps3.bin, and where is the location of this file on the nand. What should I do to unbirick nand with progskeet?

I'll really be appreciated if you answer. I don't know what am I supposed to do.

I'm wating your answers.
