How do I update my Miyoo Mini + to install Onion?

[Q113P]

my stock firmware on my Miyoo is 202305052130 and I'm having trouble updating it so I can install Onion. I got the Miyoo mini upgrade 20220419, took a new sandisk sd card formatted it to fat32, than put the firmware from the firmware folder and also the stuff from TF card 1. However it didn't work so I went and searched for a newer most recent tutorial video. I found one from Retro Handheld. I added their updated img for miyoo mini + on the sd card. Then I finally got a firmware update screen. However about 5 minutes the screen glitched then it glitched again in another 5 minuets. I never got a charging screen so I unplugged the device like 5 minutes ago so it doesn't overheat and cause a fire (since it was more than halfway full anyway). Now my device doesn't boot at all and only a black screen. I need help not only to get it working again but to install Onion on it too. Can I pleasev get help.

Fw version 202305052130 is the latest version for Mini+. You shouldn't be trying to downgrade, especially not to 20220419 which is for regular Mini only.

oh it was? dang I had a feeling. Is there a way to fix it? like try to find that fw version and reinstall it.

The only one that's available for download is 202303262339, afaik.

oh dang. I'm going to see if Onion could still install.
edit:
dang can't install it either. I hope there's somthing else i can do

[Q113P]

I no longer need this since I figured it out and reinstalled both firmwares and have the device working now
