I'm well aware that this is a warranty voiding exercise, but stay with me for a bit...
I had an ER-Lite that the USB flash died in it. I've since replaced it with a SanDisk USB flash drive and will keep it in my lab for testing.
My issue is however that after restoring it and installing a new image on it with EMRK (https://help.ubnt.com/hc/en-us/articles/204959514-EdgeMAX-Last-resort-recovery-of-failed-EdgeOS-device) I can't log in to the GUI.
I can log in via a serial console with the default ubnt/ubnt user, I can create a new admin user and log in with that user also on the serial console, but I can't seem to use either of these accounts to log in to the GUI. Any pointers on what may be going wrong?
