I previously created an issue but needed to reopen as my understanding of the issue has changed.

Specific info that may be useful:
I have an NTSC-J 50000 console with a dead clock.
I have the PSBBN english patch installed to the internal bay with an SSD.

Issue:
After installing mechapwn, the software works as expected except PSBBN stops booting entirely.
Upon booting the console, The intro plays, and after 15 seconds of a black screen, I am greeted with the default browser without any input from me. I can assume PSBBN is attempting to load but disagrees with something.
I have troubleshooted with the PS2 Scene discord, and CosmicScale himself and they all have not seen anything like this before and was directed here.
(Youtube video attached shows what happens, The video is copied from when I was talking to the discord to ignore the fluff. skip to 0:10)

I would love to know if there is any way I can fix this and go back to playing my PAL games I own.

Currently I have MP uninstalled and PSBBN running as I can only have one or the other.

There can be various reasons for such behaviour. First: there is modchip installed. Second: you were using old version of the mechapwn that does not work properly with japan models (please use latest dev build). Actually, I dont heave any other availabilities for this. Please provide ps2ident dump after mechapwn installed.

This console is pretty mint and untouched by the looks of it, however i tried all the usual boot combos and nothing happened, plus my VOID seal appears to be untouched as well.

I have the MP running from your hyperlink, However I can only boot games from uLE and not the "Launch Disc" menu item, If i do, it will just loop the console in and out of the main menu.

PSBBN still has the same booting issue as before, hopefully the PS2ident dump will help. Thank you so much for your time.

Are there any updates on this issue? Otherwise I will remove MP to get the console functionality back for now. Thx
