Forum discussion:

• Latest firmware for PinePhone modem! by Subsentient

About the latest firmware (version number 01.003.01.003):

In a GitHub issue sent by someone who updated their firmware to version number 01.003.01.003, repo owner Biktorgj replies:

There have been some reports of some issues during sleep with the latest firmware, so you might actually want to downgrade to EG25GGBR07A08M2G_01.002.07, which looks more stable.
Plus points, modem-power won't complain after downgrading

Thanks Biktorgj for all his work on it, that's one people vs. all the obstacle the hardware manufacturer creates.
