In the second part of the video where you say you are writing the display shows “reading RFID”. No matter how much I try I cant write to those cards.
Yeah, kinda weird that it says reading but it wrote it. I made more than 1 copy and tried different cards that I had and they all worked.
I did it again and it worked just fine. Edit: I’m on the new upgraded Unleash, the last one was done with an older version.
Have you found any RFID’s that you couldn’t copy to? It’s either that we both got different internals somehow but the same plastic cover, or theres something wrong with my flipper. It does emulate fine and write to one type of rfid so far.
The problem is definitely in your tags. The enclosure might look the same, but on the inside it can be anything. You’ll need something like a proxmark3 to know for sure what’s wrong with them, but I can certainly say that if you can write to at least one tag, everything is OK with your device
I have the same problem, but if the hex is equal to the token, flipper writes, if it is different it does not.
It doesn’t write at all. The hex is equal to the token so when flipper verify it did wrote the values are the same so flipper thinks that one of the methods to write did work while in fact it did not, it’s just that the data it’s the same so when flipper reads to see if it did write what was send the values that it read are the same it attempted to write so it thinks it did wrote…

As it says in the screenshot, this card is either non-writeable or write-protected
Also, what @Spildit said is absolutely correct
I think the majority of problems related to this will go away when flipper is able to write to EM4305 as those are most likely the most popular 125KHz RW tag …

Well, the most popular one by far is the T5577, to which the flipper can already write, but yeah, EM4305 are definitely on our minds

EM4100 don’t work either

The same thing happens to me that says, [@Spildit ] only write if it is the same hex, otherwise the message appears on the screen. the card is EM4100
EM4100 is not writable
EM4100 data can be written only to T5577 cards (and EM4305 in the future), as the EM4100 cards are read-only by design and cannot be written to.

thx
I do have several bags of 100 units that i did get from ebay and they are very cheap and all EM4305 … Even when buying T5577 there is no certain way to know that they will not ship you EM4305 because they are just the same visualy (look the same on the outside). Mines are cleared marked as EM4305 on the bag and i can write/re-write to them with other devices like the icopy and the NCF-PM5…
Fully true.
To follow up on this …
I’M NOT AFFILIATED WITH THIS SELLER BUT … I did buy those : (leaving here for reference) - 50pcs New RFID 125KHz Writable Rewrite T5577 Keyfobs Proximity Access Tags | eBay
And they FULLY WORK !!!
Those are REAL T5577 and they look like NFC blanks. The posted pictures of the amazon listing look exactly the same as my EM4305.
Tested to write Indala and IoProx. Tested with my work access card (IoProx) and it duplicates fine, flipper writes ok and reader detect the copy as original.
Another photo (sorry for bad quality)
My advice is to avoid chips that look like EM4305 as flipper can’t yet write to those…
Furthermore if i read my empty new tags i do get this :
While i can’t get a thing out of my empty/un-written EM4305 ones (i only get data if i write to them with other tools) Flipper can READ from written EM4305 but will not get a thing from full empty ones (will keep on trying to read them).
EDITED :
~
Just a follow up, i did FORMAT my new tags with KeySy and flipper now keeps attempting to read them using both methods without managing to do so unless i do write again to the tags,
Meaning the ones i did get and mentiones were simply pre-written by the seller with that empty EM41000 value.
And this reminds me … it would be GREAT to have an option on flipper to FORMAT the cards/fobs …
I am having similar issues with these exact fobs.
I am able to write EM4100 type cards fine, but am unable to write H10301 type cards.
Do you know which type isn’t working for you?

Out of curiosity, I tried writing every format that Flipper supports. Here’s what worked with the https://www.amazon.com/dp/B07GBSP8SD fobs:
- EM4100
- Indala26
- IoProxXSF
- Viking
- Jablotron
