I've got a Nokia 7.1, which in System-About Phone says it is a 7.1, TA-1096. But when I sideload a stock ROM (to move from Oreo to Pie) it says 'E: package is for product CTL_Sprout but expected B2N', and refuses to install it. My understanding is CTL-Sprout is the 7.1, and B2N is the 7 Plus.
It also:
- fails to find that any OTA updates are available despite being on 8.1;
- won't take a B2N ROM by sideload (says 'E:failed to verify whole file signature', 'E:signature verification failed' and 'E:error 21'); and
- interacts fine with ADB when booted or in recovery, but isn't recognised by the fastboot devices command when in 'download mode'., so I haven't been able to flash TWRP.
It all seems strange to me, but I'm not very experienced. I originally put the phone aside when I found there was not going to be a bootloader unlock, and am keen to now get it to Q and try to root it. Does anyone have any ideas? Thanks
