Hey all,
At the moment I’m using Cyanogenmod 11.0 on my Huawei Y300 (Rooted of course + CWM). All the versions are Nightly, but I don’t really have detected any flaws yet. You should try it!
You should google: Dazzazo Cyanogenmod 11 Y300
I’m sorry I can’t send you the link, but the forum doesn’t allow me to yet.
Beware with Dazzozo’s CWM: Recharging with your phone turned off will glitch (Phone will still be loaded, but freezes on begin screen so you should remove the battery if you want to start the phone). Even though I’m too lazy to change, I’d suggest to use TWRP.
