Cannot refresh dump once it has been downloaded (App) #299

rsurgiewicz commented 3 years ago

Hi,

I don't know if I'm doing something wrong but steps to reproduce:

Using app

  1. Clone a card e.g Mifare Ultralight
  2. Download dump
  3. Modify content
  4. Upload dump
  5. Download dump for verification --> modification is "present"
  6. Clone same card again
  7. Download the dump --> still dump is a "modified" one, but should be cloned from source card //expected to see source card data read
  8. Close app/ change card type/ refresh etc
  9. Close same card again
  10. Download the dump --> still dump is a "modified" one, but should be cloned from source card //expected to see source card data read

The only way I found to completely "clean it" is to connect to windows app and "Clear" Then again in app Clone same card & download the dump --> finally shows the source card data.

Q: Is it a bug? Q2: How to re-read the source card content and dump?

Hi @rsurgiewicz, I suggest you open an issue on the repository of the app you are using. This repo is for the official firmware of the Chameleon-Mini. If you encounter a problem specific to the Chameleon-Minis firmware I am happy to help.
