My E3 V2 is about 3 weeks old.  The board is 4.2.2 and does not have BL touch.  The lcd panel shows V 1.0.2.  I'm having a problem and was advised to get current firmware which is why I'm here.  I went to your downloads section where the best choice, to me, seems to be the Aug 24 version--

Ender-3 V2_4.2.2-32bit

Marlin-2.0.1 – V1.0.2 (Factory Firmware)

which I downloaded BUT DID NOT YET INSTALL.  After un-zipping the name is "Ender-3 V2_32bit_ 2.0.1V Latest Firmware_0814.  Now, it should be clear that I have very little experience and that I am confused, because of the different version numbers.  So--is the Aug 24 version above the same as I already have, or is it actually a newer one?  Thank you!

The one you just downloaded is as same as the one you have in the printer! Other firmware you see in that section are for different mainboard or Bl touch.

What problems you have with your printer?

Thank you for your reply.  I guess I had forgotten to reload the site until this morning because I just saw it.  As closely as I can remember, it was printing just fine and then it wouldn't.  I'd put in a new .stl file, get the temps up, press print and it would immediately show 'back' and nothing else would happen.  Tried reformating cards, different cards, different .stl files and nothing worked.  I haven't done ANY type of tuning or updating as yet so that should not be the reason.  After 3 or 4 attempts at flashing and .bin file renaming, I finally got it to make one print then it failed.  Renamed the .bin file again and it worked--still printing that file. Remember--I did not have benefit of your reply until this morning so I didn't know which update to use and it appeared that I already was using the latest one--a further doubt for me!  It loses a lot in translation considering that I know so little and my explanation is good only so far as you can read into what I'm trying to say.  It's a little like my trying to tell you my understanding of how to build a nuclear reactor!  You have an incredibly difficult job, especially as we have to type and there is no face-to-face. I admire you!
