Comparing...Takes a while on big nands
Bad Block ID @ 0x006F [Offset: 0xE4F000]
Bad Block ID @ 0x0088 [Offset: 0x1188000]
Bad Block ID @ 0x006F [Offset: 0xE4F000]
Bad Block ID @ 0x0088 [Offset: 0x1188000]
Nands are the same

I try re soldering and reinstall drivers but the erros continues, is safe to create .ECC and continue do RGH?:facepalm:

Im not too sure but from what I was reading all that means is you have 2 bad blocks and j runner successfully remapped both of them for you so you should be good. 378 thru 37f (8 items) = 1 bad block. Same with 440 thru 447

 

[lucifer]

yes! you are safe to write the ecc file.

As AllyNerd rightly stated, you have 2 bad blocks for which the data has been located in the spare area.
