Yesterday while working, my PinePhone, from what I can tell, ran out of battery. I plugged it into a charger but it wouldn’t boot. It wouldn’t boot with or without the battery. I tried flashing a brand new SD card but it still wouldn’t boot. On investigating, I appear to be getting the following boot loop.

EDIT: When the battery is removed and power given via cable, the device boot loops as above. When the battery is inserted, it boots only once before halting at the kernel line.
If I hold down the RE button on the back, it does see MMC devices but it simply bounces between the two. From what I can tell, MMC1 is the eMMC and MMC2 is the SD card. But in the uboot prompt, MMC 0 is the SD card, MMC 1 is the eMMC, and MMC 2 is…nothing?
UART with RE Button and fresh Phosh, or, Tow Boot, SD card

I’ve poked around the uboot prompt, but I’m unsure what if any action I should take. Is there anything further I can do for troubleshooting?
