I secured myself a never used 2001A with only 2.85 OFW installed, at the same time purchased an E3 NOR Flasher, I managed to mod the console without having to open/use the Flasher. I enabled the QA Flag on the console. I contacted the seller and I can return the Flasher, so do I really need to keep it? I asked and the answer so far is that unless I update it to a newer OFW, or I want to mod another console I won't be needing it anymore. But what about updating to a newer CFW? Some users recommend a downgrade prior to move it to a more recent CFW. Any opinions of different scenarios appreciated. Thanks.
