Hi!
I have a similar problem which was described in the topic "PBP booting but stops at flashing power led".
1. history
1.1. PBP worked fine after arrival, Manjaro booted.
1.2. Installed a nvm ssd (with x86 linux boot image from my other laptop, planned to format) I could read the files from it from the booted Manjaro
1.3. Shortly after I started up the ~3rd time I tried to update the OS with the official update tool
1.4. From this point the machine looked dead. I read forums and blogposts and I was able to install Tow-boot to SPI
1.5. Tow-boot works reliably but unable to boot anymore to any OS not from emmc nor SD
2. symptoms
2.1. tow-boot boots every time, reliably
2.2. when booting from emmc it's always start booting but rarely boot up
2.3. newest images (2022 summer) never worked since the update attempt
2.4. void linux console only image sometimes booting up and I can log in and machine looks good but wifi/bt never found
2.5. when switching to SD boot in tow-boot (or disabling/removing emmc) it starts booting exactly every second time
2.6. when it "starts booting" (regardless of success) there's a digital noise image flashing up (will attach it if I can figure out how, but similar than the lower part of the image attached to the PBP booting but stops at flashing power led topic)
2.7. I was able to boot up a Manjaro release from 2021 once (tried ~20 times one was successful)
3. recovery attempts
3.1 ordered second emmc (same size 64) -- no luck
3.2 ordered serial cable, not much help, when it starts booting and the garbage screen flashes, it is in "starting kernel" state
3.3 tried to remove ssd (read about potential power issues) -- no luck
3.4 ordered usb emmc and tried to flash images to that with rpi Images -- no luck that way either
3.5 tried to "hard reset" with the button inside, no effect
3.6 tried various images manjaro/ubuntu/void/etc on SD and on emmc
3.7 tested two SD cards, sandisk 16 (which I learned that not supported) and an other one
What should I try next?
