Can't get this to work on that one. FRP with HCU fails, but that expected. That's the info that was read by HCU:

I tried with both bootloaders, v1 and v2 - same thing. I checked if it's possible to downgrade it, but similar issue:

I also tried with Old Algo checked, but it deosn't change anything. I haven't tried without "rescue recovery", i'm affraid it'll crap out mid flash and i won't be able to restore it to a working state anything soon.
