I'm writing this post because I thing there is an error in page 10 of the Mali Graphics Debugger v1.2.1 User Guide.
When restoring the old egl.conf file it says:
cp /system/lib/egl/egl.cfg.bak /system/lib.egl.egl.cfg
and I think the command should be:
cp /system/lib/egl/egl.cfg.bak /system/lib/egl/egl.cfg
Feel free to correct me if I'm wrong.
Thanks for reporting - that does indeed look like a bug. I'll forward to our documentation team.
Kind regards, Pete
