[Question][blackbird] Is blackbird supported on iOS 12.4?

[krisanovdev]

Hi, I have some problems with blackbird exploit on A10 device (7 Plus iOS 12.4). Running checkra1n with command: checkra1n -c -k build/PongoConsolidated.bin -p Running Pongo-shell commands:

sep tz0 
sep fwload

Output:

0x120094> 0: ff 00 ff 00 00 00 00 00 8e e4 28 6f 21 15 7c 3e 
0x120094300x120094300: 93 41 64 f7 ab a1 d9 0d 9d a7 60 87 eb 0d dc fb

And SEP panic on the device side.

I guess checkra1n is not disabling TZ0 lock in iBoot for iOS < 14?

I actually don't know if our TZ0 patch works that far back, but there's a bigger issue even: we currently rely on sep-fw.img4 being loaded into memory by iBoot, and we only boot it if sepfw-booted is set in the DeviceTree.
We plan to extend this at some point; probably as a USB interface at first, and later as a NVMe+APFS driver.
