is there any possible to format an 'encrypted' t5577 card
I got an encrypted t5577 card however I forgot the write password so it is read-only now. Is there any way to "format" the card? Means disable the password and the data on it could be given up. I just wanna this card re-writeable otherwise it is locked to read only permenante. Or only way to crack the password ? This is very urgent to me and your useful help would be highly appreciated. Thanks

You know PW is 8char long + only HEX, use anything you related to like birthdates (your/wife/child/concubine), or just simple certain number 00000000, 11111111 etc or 01234567
you did trial so it can't be anything sophisticated or serious.
use iceman fork there is a BF inside for t55xx PW

As @ntk mentioned, BF = Bruteforce , you could test it out but its a very slow one.
Use the default_pwd.dic dictionary attack first. You might get lucky

Hi Iceman, thanks for your reply, which firmware for this bruteforce command integrated in? now I am using 2.5.0,see the following information, but looks like no 'bruteforce' there listed in T55xx tree nodes? how can I work it out? is there any guidance? also, where can I find the 'default_pwd.dic' file for the dictionary and how can I refer to this dictionary when running BF? what's the command format with option? thanks anyway.
