Support patching .aea otas

[mduran80]

Is your feature request related to a problem? Please describe.

ipsw ota patch currently expects a zip file. New otas encrypted as .aea cannot be used with the patch command after decryption.

Describe the solution you'd like

Use ota patch transparently

Describe alternatives you've considered

I have tried a workaround to create the cryptexes but unfortunately didn't work as there's no BuildManifest in the archive contents.

1. Decrypt .aea into a temp aar file aea decrypt -i .... -o <temp_aar>
2. Patch the temp aar file into a temp folder using aa patch -i <temp_aar> -d <temp_folder>
3. Zip the <temp_folder> into <temp_zip>
4. Run ipsw ota patch rsr <temp_zip>

  ⨯ failed to get OTA folder: no BuildManifest.plist found

Has there been an RSR since the arrival of AEA? I think RSRs are dead

[mduran80]

No, not RSR, just the iOS 18 OTA for iPhone17,1 et al. I have been using the cmd "rsr" to obtain the cryptexes from full OTAs without prerequisites. I don't usually work with deltas and it was the only way I could make it work. Is there another alternative to extract the cryptexes?

[mduran80]

I finally found a way although a bit hacky... As ipsw was demanding a BuildManifest.plist, I just copied it from <patched_tmp>/boot/BuildManifest.plist to the root of the folder before zipping. Afterwards, ipsw ota patch kindly created the cryptex dmgs.

[blacktop]

you want the full DMGs right not just files from the DMGs?

[mduran80]

yeah, full DMGs
