I'd like to update my A912 from Android 6.0.1 (113M0) to stock 7.1.2. I understood that the best way is using the burning tool, but I have a problem as I don't have the cable (I know, can be bought) but also I don't have any Windows device available as I am on MacBook.
Is there a way to update from this version via SD card? I've read about possibility of brick which I wouldn't want to occur, so is there safe image, that can be flashed via microSD?
Tried to search the forum but without any luck.
Thank you very much.
