futurerestore 182 + iPhone8 + iOS 13.4 ipsw = Unable to extract baseband firmware ?

[bigrck64]

Hello All,

To be sure to have the latest releases, I build today on my mac Mojave those repo from github:

• libimobiledevice/libimobiledevice
• tihmstar/libgeneral
• tihmstar/libfragmentzip
• tihmstar/libirecovery
• tihmstar/img4tool
• tihmstar/futurerestore

Then I tested on iPhone8 futurerestore to iOS 13.3 with iOS 13.3.1 ipsw (BuildManifest + sep d201 + baseband ICE17-3.03.03), it was successfull as expected :)

To be sure, I also tested futurerestore to iOS 13.3 with iOS 13.4 released ipsw (BuildManifest + sep d201 + baseband ICE17-3.04.02), and futurerestore was able to send the filesystem on iPhone8, but it fail to extract the baseband firmware from ipsw.

• Full log
• ERROR: zip_name_locate: Firmware/ICE17-3.04.02.Release.bbfw
• ERROR: Unable to extract baseband firmware from ipsw
• ERROR: Unable to send baseband data
• ERROR: Unable to successfully restore device

s0uthwes previously report about uncompatible SEP but not about uncompatible BASEBAND.

• Does it means that iOS 13.4 SEP could be compatible with iOS 13.0-13.3 on iPhone8 ?
• Maybe the new baseband zip format could be understood by futurerestore and let iPhone8 restore correctly ?

Have a nice day, and thanks for any idea :)
