Scarecrow

Hey all, new to the scene here. Last time I owned an Xbox was over 10 years back and I’d softmodded that console myself at the time. I bought a second hand Xbox last week though, opened it up and checked and it has an Aladdin Advanced modchip installed. On boot, it will load up blue Xbox logo before loading the standard dash. Holding the power button still loads to the standard dashboard as well so my guess is that something was reset to standard settings or the original owner just messed up and didn’t know what to do from here on. I’m looking to install a new dashboard (not sure which one yet, doing research on them) but is there anything I should be wary of if the original owner has done something to the internal files? beyond this I’m looking to them upgrade the hard drive once that is done. Is there any advice or warnings that I should know about before taking this on? Thanks!
