Wife's Nokia 8 is stuck in Download mode. I'm not sure how it got to this stage, but since it's been perfectly stable until now I can only guess it's an update gone wrong. Force restart, and restart via "volume down + power" simply returns to the black "download mode" screen.

I can probably recover it via fastboot but that will erase all data, and frankly - I'm not sure how good she is at backing stuff up, so would rather not do it that way.

Anyone else had this happen to them? Any ideas how to recover aside from fastboot?

You can enter recovery and reboot in normal mode

Would love to. How do I enter recovery? I've tried VolUp+Power and VolDown+Power - it just returns to Download Mode.

Quick update - fastboot was no help.

"Fastboot reboot recovery" reboots it back into Download mode. I got the sinking feeling it's bricked, but would love to try any other ideas.

If you turn the phone off, connect to charger, when the phone turns on and charging animation appears. Press VolUP & Power? Does fallen robot animation appear?

If not the probably recovery partition was buggered as well and the only option is go to service.

Nope. Can't turn it off either - it just reboots and goes straight to the black "Download mode. Powered by Android" screen.
I can't imagine how an upgrade could've messed up the recovery partition, but who knows.

Easily. I looked into OTA packages for Nokia 6, typical OTA update rewrites recovery, sbl, aboot partitions and selectively rewrites files on system. I reckon Nokia 8 is no different.

As far as I remember Nokia 8 supports seamless updates and has the double set of system partitions (except recovery partition). You can try switching A/B partitions via fastboot:

fastboot getvar current-slot

it should return either a or b, select the opposite slot

fastboot --set-active=<a or b>

and then

fastboot reboot

I guess nothing else unless you wanna open up the phone and short the test point on pcb. HMD hardened flashing process since Android 8 and tricks with shorting pins on usb cable no longer work. Official flashing tool OST LA requires login to update server since bootloader does encrypted challenge-response exchange.
