Help/Support Il2cppdumper Metadata problem

[Scaleysnake 1.4k iPhone 14 Plus 16.2]

when following the usual steps of il2cppdumper I have come across this. 

Initializing metadata...
System.IO.InvalidDataException: ERROR: Metadata file supplied is not valid metadata file.                                                                                                                                                                                 at Il2CppDumper.Metadata..ctor(Stream stream) in C:\projects\il2cppdumper\Il2CppDumper\Il2Cpp\Metadata.cs:line 48                                                                                                                       at Il2CppDumper.Program.Init(String il2cppPath, String metadataPath, Metadata& metadata, Il2Cpp& il2Cpp) in C:\projects\il2cppdumper\Il2CppDumper\Program.cs:line 124

is there a reason this message has come up ive attempted redumping 5 times however this message seems to popup each time. any help would be much appreciated or if this isnt the correct area for such help assistance getting there would be much appreciated also. 

thank you in advance and have a great day/night.

1/ Metadata file is encrypted
2/ Unsupported unity version

For the option 1 you can try using iGameGod to decrypt it then try load the dumper again

@Laxus thank you for the reply, would this require me to download said app from decrypted store on my phone inject igg then try decrypt it again or is there a method on the computer for the same results?

If you're jailbroken then just use native iGameGod, I dont think this feature will work on non-jb

And no pc method supported

I am jailbroken however have to Inject Igg because Igg doesn't support Roothide at this current time. Should i cut my loses and wait for igg to support Roothide?? or could it be injected then decrypted?

I dont think we will ever support roothide
You can try inject igg into ipa ajd decrypt metadata

@Laxus With this information I’m now wondering if I should disregard roothide altogether, however I’ve extracted the Global data 🤞 

Thankyou for your help.

Just confirming downloading the decrypted IPA then injecting Igg into it, then loading and extracting the global data worked. Time to see if said game is hackable. 
 

thanks again @Laxus
