I tried coldboothax on sunday night and, you know, got a reboot loop. If I had read someone already bricked I wouldn't have tried.
After figuring out why, I thought, ok, I have a rednand backup so the worst will be I'll play with rednand forever. But I still wanted to unbrick. I think it's possible because we have custom code execution in fw.img. So probably I can write some code to recover the system.xml file.
So I dived a little bit into fix94's iosuhax repo, trying to understand how to read/write files. But suddenly last night I got a better/easier idea. Since I have rednand working fine and the same haxchi vc game installed (no rom replaced), why not just redirecting mlc but keep accessing the original slc? In this way, I'll boot into the vc game inside redirected mlc, so it stops the reboot loop. Then I can connect to the wupserver, which has access to sysnand slc! And the best of all, I'll only need to comment out a few lines of code in dimok's iosuhax repo!
I went trying today and it worked as expected! Now I have my sysnand recovered!
Well, that's my story. This approach might not work for everyone who had bricked by trying coldboothax. But you know, we have custom code execution in fw.img so we can always recover somehow. Don't lose hope : )
