How to write block0 data on t5577

I have an v2.5 updated  proxmark3 v2 from china.

At frist
I'm trying to read the block 0 data with

lf t55xx read b 0

the proxmark response ::

proxmark3> lf t55xx read b 0
Reading Page 0:         
blk | hex data | binary     

So I run config command

lf t55xx config b 64

the proxmark response ::

proxmark3> lf t55xx config b 64
Modulation : ASK         
Bit Rate   : 5 - RF/64         
Inverted   : No         
Offset     : 0         
Block0     : 0x00000000

After that read again

lf t55xx read b 0

the proxmark response ::

proxmark3> lf t55xx read b 0
Reading Page 0:         
blk | hex data | binary         
  0 | FFB3C002 | 11111111101100111100000000000010

I believe the data I got is wrong
So I do set the offset in the config command. The read output changed

So could you explain the procedure of reading/writing data to the t 5577 ?

thank you

Re: How to write block0 data on t5577

when dealing with the "lf t55xx" commands...    always run  "LF T55XX DETECT" first.

Re: How to write block0 data on t5577

this is what I got, after running the command
proxmark3> lf t55xx detect
Could not detect modulation automatically. Try setting it manually with 'lf t55xx config'

Re: How to write block0 data on t5577

anyway I figure out myself.
the firmware 2.5 doesn't work.
after changing to 2.4 things work fine.

Re: How to write block0 data on t5577

did you download the latest source from github,  or did you take @asper's precompiled distro?  The v2.5. from @asper is one month old,   that may have been fixed in the source on github.

Can you compile and flash the latest on github and test?
