fredfunk (and other Benq drive owners):
If you haven't updated to the new dashboard yet, you'll want the pre-13141 firmware. If you already have upgraded, you'll want the post. Though if you haven't upgraded yet, your best bet is to use Jungleflasher and reflash your Benq to stock, using the OFW firmware in the firmware bundle under the pre-13141 directory, spoofing the drivekey from your modded firmware to the stock firmware, flash, then do the upgrade. You could always directly flash either pre-or-post dashboard upgrade to the 1.9 firmware, but the chances of MS detecting your firmware increase.
