T46-28.81.0.XX Firmware Bug EXP40

[russman]

We have some customers using the T46 phones with the EXP40's for sometime now and have never had issues with them. After updating to .15 firmware they called in reporting that none of the BLF LEDs would light up, just dark and the overall screen was darker. We found that the .20 update came out and tried that and she said it seemed a little better in terms of brightness but the buttons still weren't all lite up. We then reverted them to T46-28.80.0.130.rom and everything is working normally.
