[Sony Xperia P, U, Sola, Go] WizaJ:
Seems I did something wrong?

I followed the instructions in this post using Crunchbang Linux on a virtual machine and I got the new .elf file (I was editing the bootsplash)

When I flash it, the phone doesn't boot.

I noticed that my RLE file was much larger at 112kB compared to the original one of size 7kB.

Is there a size limit? I also noticed that there was some output from the terminal during the unpack that looks like errors.

I'm new to linux so I'm not quite sure what that means. But could that be why?
