G-Prox (32 Bit)
Hi, I have the Id ( Hexadecimal: 527F83E3 ) for a 32 bit G-prox card, how can I use this to clone the card using PM3.
In other word how to get the Raw from this Id, so I can write the Blocks 1 to 4.
Is it possible to Clone a G-prox using Pm3, directly knowing FC & CN
Cheers

Re: G-Prox (32 Bit)
thank you all for your respond,
Sentinel, how did you get the value for block 1,2 and 3.
when I write these blocks, I get the different ID: 8E4D2E5D G prox 32bit.
Iceman : I tried " Lf guard " on my PM3 Does not work, What can cause this,
Thanks for your help

Re: G-Prox (32 Bit)
Thanks Iceman,
If I may can you help me with the following issue as well,
I am trying to Clone an HID prox II fob as well, the Id that I get from PM#3 search is 9e00001fd4827f000134320 (41360), I think is 84 bit
I use " lf hid clone 9e00001fd4827f000134320 l " to clone it
But when do a "lf search" on the cloned T5577 The read out is 9e9e00001fd4827f000134320 there is an added 9e in the beginning of the new id, what causes this?
Cheers

Re: G-Prox (32 Bit)
funny thing is that I notice the same thing for some weeks ago when I was remaking the "wiegand" part and were aiming for a more unified output from 'lf search'. I thought "noone will ever notice since its been there for a long time"... and here you come.

Re: G-Prox (32 Bit)
it is very rare to find a long hid formatted card. i bet very few if any have actually used that piece of code.

Re: G-Prox (32 Bit)
hi Fidel!
I use Mullion arming station G-prox, and Wiegand indicator 
When write to Temic this:
0 0x00150060
1 0x1BC6E5BC
2 0x6F395817
3 0xB9E81BDF
Reader show 527F83E3 (32bit)
G-Prox uses 10-bit polynomial to verify the authenticity of the card
To create the correct card has to go through all the options in 1024
10-bit polynomial remains a mystery

Re: G-Prox (32 Bit)
If U want a card number to make it a clone (the original card you do not have), you will need a card reader G-Prox, and a lot of free time, because at card will have to be written Temik 1024 times, and then test them on the reader G-Prox

Re: G-Prox (32 Bit)
Hi Sentinel,
Thank you for the info,
You mentioned If I need to copy the card use PM3,
Can you please let me know How it is done?
I do not see any command under G-prox
I am using bin-2.5
Can you please clarify the steps needed.
Cheers
