I seem to be having trouble getting the OS to recognize a Micro SD card loaded into the second slot on my RG353M. Is TF2 supported?

Hey there! If you've ever used Rocknix then this may happen, you'll need to unplug the battery and plug it back in for this to resolve. This is a side effect of moving between different bootloaders between Mainline and BSP systems.

I'm having some odd power-related issue on an RG353M. 1. When installing the OS, it doesn't reboot when it says it is going to during the installation process. 2. When trying to power down the console by holding the power button and then selecting shut down, it instead reboots the device.

How do I make Daijisho run when I boot?

Reboot with HDMI plugged in

One more issue: my RGB20SX cannot output HDMI when using this BETA2 version. The HDMI external Screen goes black. On ARKOS and ROCKNIX, the HDMI output works fine.

Which language? And have you tried any other card yet?

Gamma

Freeze at select language step on my RGB20sx. My SD Card : https://shop.sandisk.com/products/memory-cards/microsd-cards/sandisk-extreme-pro-uhs-i-microsd?sku=SDSQXCD-128G-GN6MA

I loaded this on RGB10MAX3. Loaded fine. This has a lot of potential. On this device the text is super tiny. I tried upping the scaling on Daijisho and in the Android system settings and it seems even at highest it is still pretty small. Is there a solution for this? Or something that could be fixed in a future update?

Going to try it out on the RGB10MAX3.... Loading on SD card currently.

How is this image written to sdcard? Neither Balena Etcher or Rufus will do it. Theres no partition data.

I'm excited to give it a spin! The first effort was fun
