Back 2 days ago, RIM released the R9 OS for BlackBerry Dev Alpha devices. However, those who did a wipe on the device itself seemed to have I screwed up or totally non-functioning from the start. So after playing with it for close to 2 hours, seems like it can be fixed.I got mine working using the following:
1) Plug Dev Alpha into computer
2) Open device manager (right click on my computer, properties, hardware)
3) uninstalled the “RIM PlayBook CD-ROM” drivers that were installed
4) uninstalled USB Mass Storage Device that connected to RIM Playbook
5) unplugged dev-alpha
6) killed all processes that have “RIM” in them
7) Reinstalled AppLoaderWebSL_126.96.36.199.msi
8) ran desktop manager
9) rebooted dev-alpha (at this point, there should have a popup saying “BlackBerry smartphone driver installing”)
10) reboot dev-alpha again and desktop manager should prompt you that it can’t connect – click “repair”
11) press and hold power button again until you see red LED and now, it should recognize the device and sees an update and updates again.
Let us know if it works or not!
