I own a LG G2 D802, and my software version is D80220c-AME-XX. I recently found a open source code on lg website for LG G2 D802, It was a lollipop 30d source file. I wanted to ask that wether I could flash this source file on my model and if there will be any problems. Here is the link of the source file on Lg website : www(dot)opensource(dot) lge[dot]com/osSch/list?types=ALL&search=d802 {remove 'dot' and replace with "." }
My phone has middle eastern version of software as you can ses there is AME in thd software version. If the kdz file present in the link is fine for my model, can you also describe the process of upgrading software using kdz file.
Thank You
