This post is a copy paste from my BS Mobile Neptuney post.
I haven’t posted a firmware in a week already, so today I’m going to post a ROM. The firmware is compatible with BS MOBILE Neptuney. The board version is ET-86V2G-V1.1 but the firmware is for board version ET-86V2G-V1.2. Using the firmware did not cause any unwanted issue.
“You can use your favorite archive manager for RAR format You can use 7zip or File Joiner for .001 file format”
For tutorial on how to flash your tablet, when you download phoenixsuit. The tutorial is in there. Credits to AndroidXDA for the tutorial. I can’t write a tutorial as of the moment because I do not have a tablet to flash.
