One of the main reasons why the Motorola Droid sold like hot cakes in the U.S was because of its unlocked bootloader. The unlocked bootloader allowed the modding community to play with the phone to their hearts content. Thanks to the unlocked bootloader users could flash a custom ROM with tweaked settings, overclock their CPU etcetera. Sadly, the European version of the Droid a.k.a Milestone featured a locked bootloader due to which it did not do sell very well.
When Motorola announced the Droid X, the modding community hoped that the Droid X will also feature an unlocked bootloader. Sadly, it was found out that the Droid X uses the same bootloader as the Milestone. Now in a shocking move, Motorola has officially announced that it won’t allow Custom ROMs on their handset from now on.
Securing the software on our handsets, thereby preventing a non-Motorola ROM image from being loaded, has been our common practice for many years. This practice is driven by a number of different business factors. When we do deviate from our normal practice, such as we did with the DROID, there is a specific business reason for doing so. We understand this can result in some confusion, and apologize for any frustration.said Lori Fraleigh from Motorola.
Motorola even suggest people to buy a Nexus One or a Google ADP1 developer phone for flashing and playing around with their phone.
Bad move from Motorola here! I am sure the sales of Droid X and Droid 2 will take a huge hit due to this.
