While the device has its own home on our forums, the T-Mobile Sidekick 4G has been forgotten by many in favor of the more eye catching flagships from both Samsung and HTC. However, there are still many users out there using the device as their daily driver. While it may lack the speed and amazing screen of the above devices, it still offers a decently fast 1 GHz Hummingbird processor and a capable slide-out keyboard for the more messaging-centric users.
However, one common complaint from device owners is that reception and data speeds don’t quite live up to its name’s 4G aspirations. Luckily, XDA Forum Member Reviewers (one of the maintainers of the GenericGinger ROM for the device) has experimented with various modems and has found that using the modem from the recently rootedGalaxy Blaze 4G instead of the device’s native modem provides both an increase in signal and data transfer speed. Others in the thread have concurred, sharing their overall positive experiences. The modem itself was originally ripped from the Blaze 4G by XDA Recognized Developer Master&Slave™.
Installation is just a simple flash through any custom recovery. However, users must keep in mind that this is intended for either Froyo or Gingerbread builds only. In the words of the thread starter:
Modem pulled from the Samsung Blaze4G.
Not hard to install at all, just put it on your sdcard and flash in Recovery.
Yes. This was not originally for Froyo I have to remove some /libs.
I made it work for the Sidekick 4G.
Credits to Master&Slave for pulling the Modem from the device.
If you’re adventurous and wish to give this radio a shot, head over to the original thread. However, it may be a good idea to create a backup of your existing radio (or make sure you are able to find one for download) in case you wish to revert.
