I am now unable to boot from micro SD card. The only thing I have done that would be considered sensitive was flashing the open source firmware for the modem. That was the last major thing I did on my Pinephone running mobian. I only noticed it wasn't working last night b/c I flashed the SXMO image to a micro SD card. I was so excited because it seems like the best OS for me on the pinephone, just learned about it. It was a bummer to get the red led indicator.
I thought I did something wrong or my SD card was bad, so I bought a pack of 3 extra 64gb micro sd cards. All the same issue, when I press the power button with a SD installed the LED turns red and does nothing. I have done some research online but could not find a solution. I read that red LED means it detects the SD but there is a issue. I have tried 4 separate SD cards, I am using balena etcher to flash the images btw. I have used 2 different computers just to be safe. I did format and delete all the partitions from the sd card before flashing the new image. I did put in a empty sd card with nothing on it to see what would happen. Same red led.
To be clear it was working before, I have tested multiple OS's on the SD card previously. Manjaro Phosh, Mobian and I even used the SD card to make the pinephone's emmc flashable to install Mobian on the emmc. Only after flashing the open source modem firmware did I discover this issue. I only mention updating the firmware b/c that was the last major thing I did. I am not assuming it is the cause of the issue. I used GNU/Linux on and off for about almost 15 years. But I will be honest I still don't know much. So help a brother out. Thanks in advance.
TLDR: what steps can I take to troubleshoot my issue of not being able to boot from SD card?
