I just noticed that Huawei released a new firmware version for the U8950D version of the Honor+ (Ascend G600). The new firmware ( V100R001C17B949 ) replaces the previous version V100R001C17B939 and is available here. Unfortunately it is most probably a chinese firmware that should just include english as second language. However, the description says that it contains fixes for problems with nonstandard cards. This could maybe solve some compatibility issues that were reported with some SIM cards. Also contained in this new version is some change for the camera software that helps problem with red images (?!?).
Did anyone try this new firmware, yet?
