DO NOT UPDATE! There are countless posts being made asking this question "should I update?" with people telling others to update. We don't have enough information about Memchunkhax 2 or Homenuhax v2.1 or how downgrading even works wait for official releases and info from the Devs themselves people are excited I get that but updating and ruining your chances of CFW on baseless speculation is a horrible idea so i'll say it again. DO NOT UPDATE! Update : If you own an Old 3DS on any firmware do not update as we don't know how downgrading works or if it can be done (smealum says it can be done with a work around but more info is needed) if you have a N3DS or XL on firmware 9.3 and above you can (if you want to) update as 10.3.0-28 is a safe firmware and is downgradable so update to that firmware while you can.
