Haven't had time to look for new exploit yet.
But if you install appmanager before upgrading, then you can access adb again on 220519
Last night I tried to update using KIA Navigation Updater software.
Forgot to remove my sideloaded apps, thus the update got stuck in a bootloop (insufficient memory i guess).
Luckily, I could solve tis problem using
@olega59's USB keyboard hack.
In the recovery menu I chose to revert to old SW version, but it seems the latest version got installed anyway.
To my great disappointment, I found out that all sideloaded apps were gone (including app manager) and ADB had been disabled.
My current config:
Software: DE_PHEV.EUR.SOP.014.6.220519
Firmware: DE_PHEV.EUR.0.5.430.210930.MICOM
Nav app: COM5.EUR.KIA.220519.04c1b0e
Map: EUR.15.41.54.013.223.5
