I used this build last night:
20101215_235045-RHODIMG.NBH
and unfortunately it did not work for my rhod400. I got one good half lit flicker of the screen, and the rest of my attempts pressing power and end buttons I could see the backlight coming on after most presses about 5 seconds, but no 'front light' .
I just wanted to add that in the previous kernels before the changes were committed using the haret dump I gave ACL, when the 'front light' would not work, I would still get the force feedback when unlocking the phone, even when the screen was not visible. With the newest changes, I dont get that anymore after attempting to turn the screen back on. The device seems to be even more unresponsive now.
Here is my haret dump of wirq10. You can see the commands I used to get the dump. If there is anything I should try differently to get more info let me know. I am fairly tech savvy.
