53.0.1
Hello,
If it's any useful information: I just flashed the latest w/ aroma and TWRP 3.1.1.0. It succeeded but it was stuck on the boot screen for about 15 minutes before I rebooted it. My install of Maximus was only 2 days old at this point, so I don't think it to be accumulated dirt.
After rebooting, normal sequence resumed.
