My story begins with noticing: eg25manager[2815]: Rescheduling upload since modem isn't on line yet, in 30s in the log.
Was this caused by not having a SIM installed? No. Was running sxmo, is it distribution related? No.
Looked at other eg25manager log messages, then found these messages in eg25manager source code. Reduced problem by switching to archlinux-pinepone-barebone, disabling eg25manager, and manually executing the power-on/off sequence using the sysfs gpio interface.
A review of the Pinephone schematics and the EG25-G HW Datasheet suggested variations to try. Regardless of these attempts, seems the modem just never boots [as evidenced by gpio233/STATUS always remaining high [the inactive or not-running state].
Next assumption: the modem is bricked. Remove internal cover to gain access to T1500 and T1501 to enable USB_BOOT. Still with eg25manager disabled, bridge test points and boot phone. No sign of the expected usb device in lsusb after numerous attempts. A look at the EG25-G HW Datasheet timing diagram suggests a dependence on PWRKEY, so tried applying a power-on/off sequence while USB_BOOT was active. No diff.
So now, Obi Wan Kenobi, your my only hope. I've exhausted my a ideas and find no other's with a similar problem.
If you've made it this far, thanks much for your interest.
