Pyramid to t5577

HI guys.
I'm just trying to figure out the lf t55 config command and write commands for cloning my Pyramid tag.
Im not sure what LF t55 config command to use.


Heres the tag
Pyramid ID Found - BitLength: 26, FC: 9, Card: 33278 - Wiegand: 21303fd, Raw: 000101010101010101010161980efb6e         
Checksum 6e passed       


i wrote these to my t55 card and bricked it lol

proxmark3> lf t55xx write b 1 d 00010101
proxmark3> lf t55xx write b 2 d 01010101
proxmark3> lf t55xx write b 3 d 01010161
proxmark3> lf t55xx write b 0 d 980efb6e

what did i do  wrong? and can i fix my t55 so i can still use it ?

Tried a lf t55 wipe and
All i get from the t5577 is No Known Tags Found!

Still learning guys. sorry if this seems basic. Any help is much appreciated.

Re: Pyramid to t5577

you wrote a bad block 0...

and if you were unlucky you enabled the pwd bit.

Try writing a default block 0 with all zeros pwd.  or a all 0xff pwd.

lf t55xx write b 0 d 0x00088040 p 0x00000000
or
lf t55xx write b 0 d 0x00088040 p 0xffffffff

still bad tag..

thats what i copied from the wipe command..

Im not heartbroken that i bricked a $1 tag no biggie.

What should the block0 should have been? Am i reading that raw data wrong?

Re: Pyramid to t5577

Don't use 0x in the command.

-- try first
lf t55xx write b 0 d 00088040

--test with
lf t55 detect

- try second.
lf t55xx write b 0 d 00088040 p 00000000
lf t55 detect

lf t55xx write b 0 d 00088040 p ffffffff
lf t55 detect

Re: Pyramid to t5577

The wiegand raw data is what your t55xx tag must repeat.

b0  ... here goes a maxblock 4, pyramid config block..
b1 00010101
b2 01010101
b3 01010161
b4 980efb6e

Re: Pyramid to t5577

Go for @marshmellow 's fork,  he has some fixes that isn't in Pm3 master.
His fork is more similar to pm3 master too.

if you wanna go experimental, try out mine.

Re: Pyramid to t5577

That looks like an invalid block0,  so its not a good dump,  or config settings.

Look at your data plot,  post a pic of it here.

Re: Pyramid to t5577

if one of the mods wants to delete this thread thats ok with me. it got way off track. i ended up getting the pyramid tag working on a different t5577. the generic key fobs i have are not easy to read/write. i might just need more time with them in the config.

Re: Pyramid to t5577

ASK/Manchester, 32,   with STT which makes your demod not work..   STT get demoded to 0x77.

Where the actual start offset is doubtful, but this is your repeating pattern

Re: Pyramid to t5577

According to your link, you should be able to get the "LF T55xx" commands to work.

Use: ASK, 32  and play with the offset...

Re: Pyramid to t5577

After trial and error. Here is what lets me wipe and write to the these tags.
Thanks for all your Guidance Iceman. These tags were tough and will not respond to a t55 det or dump until you set this mod.
staying on topic i was able to clone a pyramid tag to both of these.
