[Q] stuck in se7en v1.6 C00B138SP01 topic

First of all excuse me for my bad English so I am running se7en v1.6 on my huaweip7 l10 C00B138SP01 I'm trying to get http://forum.xda-developers.com/asce...11-14-t2945104 (that's [ROM] Se7en-Rom v3.8 / EMUI 3.0 / 4.4.2 / B602 *BETA* / 19.12.14) I've tried a lot of times but its just not working for me or can I at least get a stock ROM from huawei with emui 3.0? I've tried to remove this costume ROM by updating it by a default update from huawei . I needed to paste the update in the dload folder and after doing that I went to local update and it was saying there was an update so my phone reboots and I am still on the same version I searched it up but can't find anything on the internet there aren't a lot of people with a huawei p7 I think ... Or maybe my question is so stupid nobody makes a thread about it. I am new to rooting and custom ROMs so please explain it as simple as possible. Thank you a lot
