why is there a Numworks logo instead of a black background ?
gray grail
I dont know but it is there just for a very sort time
fluid nymph
when did you update to 19.5 ?
gray grail
Never it was always on 19.5
fluid nymph
You bought it new ?
gray grail
Yes
fluid nymph
it was asking for update ?
gray grail
Yes it was
fluid nymph
@stark helm come here, something looks wierd
gray grail
maybe some more information i have installed .nwa applications.

don't do anything with your calculator, we're gonna need it
short answer, you can't downgrade because it has been sold with E19
but plug your calculator into the pc and open up this page: https://ti-planet.github.io/webdfu_numworks/n0110/
gray grail
done
fluid nymph
ok, connect your calculator, then click "Dump internal", it should download a file
gray grail
fluid nymph
ok
let your calculator and wait for @stark helm he will know how to get important files from your calculator (it's not always needed but since your calculator has been sold with E19 and we never saw that before, we will need this)

your calculator has been sold with e19 or you upgraded just after because it was asking you?
gray grail
Upgraded just after because it was asking
fluid nymph
Oh, it's not the same !
hollow cradle
everything's normal
fluid nymph
but the bootloader background
fluid nymph
I know that, but Numworks bootloader has a black background, not a Numworks logo
thorn coral
Never it was always on 19.5
.
gray grail
Sorry for mistake
hollow cradle
Can you make a video so we can see what happens please?
fluid nymph
ok, so the numworks logo was just a reflection
So at this point, if you can't tell which was your version before updating for the first time, it may be 16.4.3
the thing is, if you update from this version, your calculator is locked
gray grail
oh ok. But thanks for looking at this and helping.
hollow cradle
To unlock the calculator, you have to use a rasberry py
gray grail
yes i tried but. I am bit stupid so i can't open it anymore. Opend it like 2 times before i had the raspberry pi.
thorn coral
If you have the rasp pi, what prevents you from unlocking ?
gray grail
Being very hard to screw them off
