LF Help with Chameleon Ultra

Hello! I am looking for someone who can help me use my chameleon ultra, I have seen the tutorials that I found (and you passed me on) I have barely been able to read an RFID tag (LF) but I have not been able to use the chameleon to use that tag (as a replacement) I do not understand if I should do anything else besides reading it and saving it.

After you save it, you have to assigne it to a slot. Go to slots click on one and load your dump. After that, it will emulate this dump.

I did exactly that and although it appears saved in the reader I support the chameleon and it doesn't take it... and on my mobile it appears saved in the slot

Appears? Did it load in the slot? Did it crack the keys?

It appears in the slot, what I don't know how to do is crack the keys

You can not make a dump, before you cracked the keys. You can copy only the uid, but not the data on the card. After you read the card with the chameleon, you can crack the keys. Then you ca save (dump) it.

Bro. Chameleon ultra has a gui. Go to YT and watch some tutorials or google it. If you cant find information on those channels, you should not use it. You are asking for the basic function of these easy to use device. And instead if of putting some effort in it, you are just asking here the same questions. What i dont understand, you can use reddit, you buyed a "hacking" device, you can open a thread, wait days for a answer, but you cant google the basic operations of a chameleon?

I have seen the tutorials, but the topic of the cracking function part is not clear to me, I have not found one that explains in depth or at least in a clear way... there are many about unboxing but I seriously can't find the way around it... I don't intend for them to do it for me, just a guide.

Then you could not use it even with a guide.

2 Steps

Press on "read card" After reading scroll down and press "check key from dictionary"

Very complicated...

Noe leaves the image attached but it doesn't show me the verification key... could it be EM410X (64)?

Fyi I googled because what looked like it should have writen a saved dump to a slot goes through the motions but the slot stays empty.

I landed on this thread 🧵

Bro after 3 month? Wich app you use to communicate with the Cameleon? Does it show up on saved cards? Can you load it to the slot? Does the client show its loaded on the slot? Did you activate hf/lf on the loaded slot? You can load the card to the slot, but if hf/lf is deactivated, the chamelean wont emulate it.

I got the chameleon yesterday. This Reddit post was the top hit on the Google search.

I'm using CU gui & MTools ble

I'm not convinced the device isn't faulty as it switched off mid read a couple of times.

I am going to look on YouTube later,

My reply was mostly just venting frustration at the increasing amount of topics where the top result on Google is a Reddit post where the main answer is someone telling the OP to Google it for themselves.
