    What I got in this new update:
    – Sony has patched perf_event exploit (by geohot) with 20.1.B.2.15 kernel, so I need to flash 20.0.B.0.64 kernel to reroot this firmware.
    – Camera quality seems to be improved a bit
    – VPN settings FC bug still not fixed (although I can use VPN apps)

    Gonna bet that would be the last major update for E1. Enjoy your last update, suckers!
