Despite not having their own forums, there are a lot of obscure and unpopular devices with outstanding developer support. It’s generally assumed that the big name devices will get updates and AOSP, but when lesser known devices receive support, it seems almost like a bigger accomplishment. Now, the Huawei U81xx series has gotten CM9.1 and CM10, the Samsung Rugby Pro has a 3.0 kernel along with an official update to Android 4.1, and the Rugby Smart has a 3.0 kernel.
The Huawei U81xx CM9.1 and CM10 ports were built by XDA Recognized Developer Alberto96. So far, users are reporting that the ROMs are pretty well done. Of course, these are early releases, so there are a myriad of small bugs and issues that need to be fixed. However, there has been no reports of any serious issues. They may not be daily driver ready, but they’re well on their way. So if you have a U81xx series device and you’re looking for some AOSP goodness, these are worth at least trying out.
XDA Senior Member kemonine96 has posted the CM10 for the Rugby Pro, along with the Odin package for the official Android 4.1. This is a double dose of Android 4.1 for the Rugby Pro as users can now choose between AOSP and official 4.1. For the official update, root and recovery from the prior versions still work.
Lastly, XDA Senior Member Motorhead1991 has released a 3.0 kernel for the Samsung Rugby Smart. It’s experimental right now, but most have reported that it’s still pretty useful. Here is the list of working and not working:
