Hey Maco, I'm so glad I found this, the blindingly-white always full brightness splash screen was such a pain to me. I flashed the inverted white on black stock screen you posted, worked great no problem...
I wanted to try making a small edit to it, so I took that zip, unzipped the contents, and edited the .bmp in GIMP... Saved it, put it back into the .zip, moved it back onto the phone (via Dropbox), back into the sdcard's root... I verified that zip is correct through opening the .bmp inside it in Astro. When I flash it, it says it's successful, but I still have the original inverted stock screen.
I'm guessing there's something that has to be done with the .img file... so I'm lost. xD What am I doing wrong?
I'd be happy to share it once I can flash it myself! I blacked out the EVO 4G part, centered the htc logo, and put SUPERSONIC in a light blue underneath..
