I have been experimenting with several different roms for the huawei m835 and these are my top three: 1. Miui (v6) for the Huawei u8150. 2. Cyanogen mod 6 for the Huawei Ascend. 3. DroniX (v4) for the Huawei m835. Note: If you like any roms that are not on this list, please feel free to comment and tell me. I would like to try them out. Thanks.
