Huawei P9 Lite (Android 7) & General questions - Android Q&A, Help & Troubleshooting

Hi! First of all... Sorry for bad English! I am German and was smoking to much in school.
I hope you understand what I mean in this post. So lets begin...
I don`t want to call anything bad here on this forum, or criticize anyone of you. I am very grateful for the many work and time that most of you spend for all of this. But I am a newbie and must write something, that myself and many other newbies are thinking, but not writing, about many threads. As an example,
the Thread "{Android 7 - EMUI 5.0} VNS-L31/L21/L11/L23 C432B329 {FULL/LEAK} [28-11-16]", linked here:
http://forum.xda-developers.com/hua...t/android-7-emui-5-0-vns-l31-l21-l23-t3513816
I read about this Android 7 firmware and was very interested to flash it. But as a newbie, I wanted to collect as much information as possible about this firmware (general Informations, How to flash, Problems, what to do if it fails, ...). Because I think that this forum is the best at web, I searched for these informations here and began to read everything I could find about it. But on most threads, like my example thread, I have a problem, because I did not understand, if its up to date or not. And if the problems, other users write about are still there, or if they were fixed allready. There are to many posts, where users write about different problems. So it often makes me confused, because I am not sure if answers are for problem user1 posted or for problem that was posted by another user. If its quoted, ok. But its still very difficult to understand what is up-to-date and if problem would be fixed now or not. Sometimes I read all of these posts and at the end I understand nothing anymore, because everyone is writing about different problems. So it feels like chaos for me. Then it happened that sometimes users say that there are no problems anymore, and at next page someone writes that there is still problem. Some users post links to websites, threads or files and next user posts links to websites and files too. And then I am thinking about, if they are writing about same problem, if I need all of these stuff or not, what I must flash first, if problems exist if I flash linked file from user1 or if it might be fixed at linked file from user2, .... Then I asked myself which one of this is the newest and up-to-date and if this was the one I get shown at started post on first page (I mean If it was updated by thread starter or if someone posted a newer version at example page 23 of all replies)? How I know if these informations on page 1 are still up to date? At moment I did not understand if there are still problems, or not. And which of these files to flash, to fix problems. After many days I was reading now, I am still not sure if I could flash this firmware on my Huawei P9 Lite (VNS-L31 C432 B161) without getting problems, I read about. As an example, problems like these:
-Is camera working
-keyboard working
-display showing all ok
-mobile data working
-and others
And I don`t know if I must download and flash the files, posted on first page, to become most newest / most stable version, or if I might must read all pages of this thread, to find something posted, thats newer than information on first page? All together... my final question is: Are these informations and files that were posted on first page, all I need and up-to-date for flashing this firmware?
My greatest wish would be a general thread, where I could find all informations and files categorized in different threads, so that newbies like me could understand it better. As example, the thread "Huawei P9 Lite Firmware Compilations by ErvinSoliven", that were opened today by ErvinSoliven and linked here: http://forum.xda-developers.com/hua...huawei-p9-lite-firmware-compilations-t3517124
I opened it and it shows me all the information (hope soon actually ) I was looking for, without reading all of the replys on many pages. This I think is a very good example thread on how to categorize different themes. And I think it would reduce questions, that were allready asked by other users for 5 or 6 times before. So If someone were willing to invest so much time for things like that, I would be very happy and grateful. Who wants to be that hero?
But at first, it would be the most important thing for me, if someone could post an up-to-date information thread about
flashing Android 7 on P9 Lite (VNS-L31 C432), inclusive
-links to needed files (Recoverys, Images, Fixes for camera..., and how to do it)
-informations what is fixed or still not working
-what to do if I get problems during it
It would really really help me, because reading so much posts, in a language that I did not understand very good, is very hard for me and makes me not sure, if I am doing all of this right or if I might did understand something wrong or choose wrong file, ...
I hope you all understand these things, I want to tell you, in this post here. If not, sorry again for this bad English! I tried my best.
At the end of this post, I want to say something again...
"Thanks" to all the people that have so much patience, spending many time and many work, for this great forum and teaching newbies like me! You are the best! Many thanks!!!
