Hi,

Where to the this PKG file ? Can it be downloaded from official site ? or copied from some digipaper folder ?

[HappyZ]

Here is the link where you can download the original pkg:

<Distribution 
  ID="Firmware"
  InstallParams="" 
  InstallType="binary" 
  MAC="b13e781d7f6be196041421da629c375b"

Thanks ! The last question ;) Where I can get this removed from github files like start_eufwupdater.sh and so on ?

[HappyZ]

what you mean? start_eufwupdater.sh you can find it online actually.

@janten I have been thinking and reading the reversed code and below are several thinking directions

1. testmode needs special private key to enable - wait till RSA public key can be broken (if finding primes for it, which is highly unlikely)
2. pkg can be unpacked/packed but again require an 2048-bit RSA key to sign - dead road probably
3. finding security vulnerabilities in reslet framework 2.3.12
4. preventing usb ethernet mode + enabling adb
5. ?
   I don't have much time for 3) and 4) or 5) now, but if you have more thoughts discussions are welcome.
