No it won’t
you’ll often freeze tegraRCMGUI when you attempt to inject the payload twice (after you’ve already injected a payload prior without power cycling the console) so imagine this is normal.
Just use the Biskeydump payload here instead anyway, as if you haven’t got the correct files on the SD, you stand the chance of the newer hekate versions not enabling backlight (as, if I remember right, the newer Hekate versions won’t even enable text only mode - unlike the older versions)

Scroll down to the Biskeydump download section, download V9 and extract and inject this bin file (after power cycling the console)
