GW's a9lh.bin payload will work up to 11.0.0-33 SysNAND. The problem seems to be that he didn't properly format his SD Card to remove his EmuNAND, as such GW still sees it. Black screen after seeing the dragon logo, is usually a symptom of this, from the people I've helped fixed this issue with in the past.By any chance your sysNAND is upated beyond 9.2? That might be the case...
EDIT: From your posts it seems you have 11.0 on sysNAND and 10.7 on emuNAND
All you are going to do is format your SD Card properly, so yes, it'll work. If you setup your A9LH setup the way Plailect's guide recommend you do. Then just hold Y at boot time, and it'll open EmuNAND9. From here we'll want to.It work with 11.0.0-33U if i do that? haha
