MyMinUI
This is a community fork of the popular MinUI CFW. MyMinUI can be installed on the G350 by using the R36S custom image. This is a little more involved, as you will need ArkOS as a pre-requisite. The instructions below are as written in the Readme.txt that comes with the firmware download.
NOTE: This is still an EARLY way to get MinUI running on the device. If you have your heart set, it will work, but you may be better off waiting a little while for a dedicated release to come along for the G350. This is not an image designed for this device, and as such, there may be issues in places with compatibility such as controls and display. If you run into problems, check out the device channel on the RH Discord.
MyMinUI is built over the latest ArkOS image for R36s available here
At first, you must install ArkOS, and follow the installation instructions provided by the ArkOS support page. If you have a Wi-Fi dongle configured now the network to get is working even in MyMinUI.
Once ArkOS is successfully installed, create the folder <EASYROMS>/roms/MyMinUI in the SD card, all Roms/Bios must be saved here. You don’t have to use the rom/bios folder structure of ArkOS.
- In the release file (i.e. MyMinUI-YYYYMMDDb-0-r36s.zip), there is a folder called “r36s”. Copy that folder as is in the <EASYROMS>/roms/MyMinUI/ created the step above.
- Move (or just copy) the file r36s/EnableMyMinUI.sh to the folder <EASYROMS>/ROMs/tools/.
- Copy also the whole release zip file (leave it zipped) in the <EASYROMS>/roms/MyMinUI.
- Insert the SD card in the TF1 slot and boot the device.
- While in EmulationStation go to Options->Tools then run the tool EnableMyMinUI.sh and wait for the device to reboot. The installation process will start showing the screen “installing MyMinUI…”
- Once the installation process is completed press the PWR button to shut down the device, remove the SD card, and insert it in the pc.
- Now You can fill the bios and roms folders with Your files. Put the sdcard in the device and play your games.

ARKos or PAN4ELEC?
I’m a big fan of what’s happening with Pan4Elec on this device!
I installed ark OS and the right thumb stick mapping is wrong. Up is right, down is left, left is up, right is down
Any info on how to fix the right joystick issue? It seems that when ArkOS is installed the stick configuration is rotated 90 degrees anticlockwise. So left is up, up is right etc. I tried a few fixes that I found here and there but none fixed the issue so I had to go back to the StockOS ( even though I liked ArkOS more )
Go to https://github.com/retrogamecorps/G350-ArkOS-dtb and download Image and replace the in the boot volume
I wish I would’ve seen this before I played and created save states. I lost my save state in my favorite game and now I can’t save any game (it freezes and gets stuck at saving 0%). Is there a fix like a cache refresh in the original software or is it cooked because of the SD card? If so is it still salvageable to transfer to Arkos and keep all the games it came with?
I played my game when I got not knowing I had to do anything else to it now I turned it on and it says no SD card. What should I do I
My menu hotkey is not detected in retroarch can anyone please help me with this
Hi Paylyboy390,
I’ve had the same problem. Did you find a solution for this?
Yes a proper dtb swap is needed you have to rename the batlexp dtb to rk3326-rg351mp-linux.dtb
You can find Batocera and rocknix for the g350 at my github
