Huawei Honor 6x Repair (Camera and Screen)

I was looking through the site and was glad to see that there are Huawei phone repair guides, however, I did not find a guide for my model. I have the Huawei Honor 6x, is this guide available or will it be made available soon?

My issues with the phone are: 1) the screen is cracked, 2) the camera glass for the rear facing camera cracked and I removed it so now the cameras are exposed, 3) since this happened maybe about a year or less ago the rear camera (s) have accumulated little dust or debris within/on the camera so when I take pictures with that camera there are little specks making the images look terrible. Also, when the camera faces the sun or a lot of light is brightening the shot, the camera produces a weird glare that looks like the camera could be cracked or humid, I am really not sure. I really would like some help figuring out how to repair the phone, I would rather not buy a new one.

I have read about suggestions to replace the camera, or use a pressurized air can to blow the debris out? I tried vacuuming the camera with a small attachment my vacuum has but there was pretty much no difference.

Also, if anyone has information about the double rear cameras the Huawei Honor 6x has would you be willing to explain to me exactly how to make use of them both or how to use the feature? It really only seems like one of the two cameras is ever being used at a time and I think it’s the top one. Thanks!
