Using the instructions from http://huaweinews.com/2014/01/android-4-4-ascend-g510/ I have managed to root, unlock and install the 2014-08-02 CM11 nightly from http://getcm.thebronasium.com/?device=u8951
The CWM I use is the one from here: http://www.modaco.com/topic/367021-kk-444-cyanogenmod-110-rom-all-nightly-builds-available/
So far so good. Things are snappy, I was able to install the Google apps. I'm super satisfied with it.
However I have an annoying problem. When I try to download an OTA update of CM11, like the latest build from today 2014-08-04 http://getcm.thebronasium.com/?device=u8951 the download goes ok, but then when I want to install it (phone restarts into recovery) I get an error that says that file is not found! and the phone reboots in the current CM11
The only way I could install the update was to manually move it from the Internal Card to the SD Card, where apparently he expects it to be. After I manually made the move, I went again to the usual location in android where you manage the OTA updates and restarted the update process. This time it worked!
My question to you is: what do I have to do to make the OTA updates download to the SD card and not on the Internal card?
