Hi, just want to comment on your video. Based on the presentation your phone does not have ramdisk, slot A partition only and SAR = Yes. You need to qualify specs and level readiness as mentioned by Fendi (QEM Unlocking enabled, USB debugging enabled and etc.) Hope it would not misguide your viewer. FYI
Good question If I starts showing you how to install custom recovery the video will go longer BTE there's a lot of videos are available on RU-vid You can search for your phone
