Finally there is some great news for Samsung Galaxy S II owners as CyanogenMod team will start pushing CM 7.1.x Android 2.3.4 Gingerbread nightly ROMs soon. The announcement was highly appreciated as soon as it was made on twitter and some other portals by a vast majority of SGS II users. However, as Nightly builds are auto compiled and pushed to a specific web location, so it might take some time for this ROM to show up on your ROM Manager Premium.
But if you can’t wait and really want to have a go at CM 7 official nightly build for Samsung Galaxy S II, then the ROM is available for manual downloading and flashing. For those who don’t know, CyanogenMod ROMs are third party Android firmware designed for rock stability and for enhancing overall user experience. Nightly ROMs are highly experimental builds, possibly filled with issues and glitches, which are consistently tested, improved and optimized to grown into release candidate and stable versions. It is needless to state that nightlies aren’t advised for folks with less exposure to flashing, rooting and fixing any errors that occur post flashing the ROM.
In case you are ready to test the awesomeness of CM 7 on your Samsung Galaxy S II, then follow the guide below:
