Buy the RG405V here: bit.ly/AdinGoGame
A HUGE THANK YOU TO "THEGAMMASQUEEZE" for all his hard work
I highly recommend watching this installation guide on a bigger screen (not your phone)
All you need is internet, a computer, a USB-A to USB-C cable and your RG405V / RG405M / RG505
This installation will work for either of the above mentioned devices.

Oh dear! Well according to TheGammaSqueeze the only reason it’s in Beta is because the fan isn’t working which I think is superfluous anyway.

i was stuck in deciding between the stock OS and the Gamma version of the 405M, I read there's been some issues after updating. And it's been a while since I rooted an old android phone years ago so i'm a little bit apprehensive. the Gamma version is a tad more expensive. This video made me take the plunge just a few minutes ago. Getting the stock OS version and I will tinker with it if and when it becomes overwhelmingly necessary. cheers!

[@poobs2361]

Hey man, this is a fairly new device so it's hard to find any modding info specifically for this model. I was wondering if you had any idea how to pull the boot.img for the stock OS to use for Magisk. I'm trying to get some live service android games to run that are currently detecting root on the device and don't launch as a result. I wanted to pull the trigger on gamma OS but I wanna wait for a build that fully supports fan control and battery optimization for sleep mode, right now the android OS does everything I need it to do outside of the hideousness.

[@adinwalls]

Okay. I haven’t gotten into anything like that. We would have to ask TheGammaSqueeze. I believe the fan is making a difference in some gaming situations but honestly the overall improvements are worth it for me. However OTA updates aren’t available yet so I can understand that some people want to wait before going ahead.

Zarchiver doesn't want to extract anything, 7zip does but dolphin tells me the file doesn't exist. I cannot believe how difficult it now is. I honestly wish I wouldn't have bothered with gamma. I had a good system before but now that everything is gone because I left it all on internal storage, I can't even get it back. So how does anyone else actually get games? Not downloading them, but getting them in the folders, extracting and making them work?

Hey there. Are you extracting games on Android or on your pc? Because it would be better to unzip the on your computer and then add them to a folder on the device. Make sure they are rhetorical correct file format. And then set them up in the emulator.
