The "Looping" Update: If your TV gets stuck in a boot loop after an update, perform a "Forced Factory Reset" by holding the Power and Volume Down buttons on the back of the TV while plugging in the power cord.
USB Not Recognized: Ensure the drive is formatted to FAT32, as NTFS or exFAT may not be recognized by the 43W800C during the boot phase.
Slow Performance Post-Update: After a major firmware jump, it is often helpful to perform a factory reset from the settings menu to clear out cached system data from the previous version. Maximizing the Life of Your 43W800C
While the 43W800C is an older model, the hardware is still quite capable. If the built-in Android TV interface feels sluggish even with the latest firmware, many users recommend using an external streaming device like a Chromecast with Google TV or an Apple TV 4K. This allows the Sony hardware to focus solely on picture processing while the external device handles the heavy app lifting.

I’ll provide that complete guide now.
As of late 2018, Sony ceased firmware development for the 43W800C. The final release, PKG6.407.0138, carries a date code of October 2017.
The implications of frozen firmware:
Sony released several major firmware revisions for this model. The most significant was the leap from v3.905 (Android 5.1) to PKG6.404.xxxx (Android 6.0.1).
What the changelog didn't tell you:
Because Sony abandoned the 43W800C, the community has stepped in. Projects like Lineage TV (Unofficial) and LolliW800 attempt to replace the Sony launcher with AOSP (Android Open Source Project) 9.0.
The technical hurdle: The display driver (mtk-tv-disp) is proprietary. Without Sony's binary blobs, custom firmware cannot control the backlight or local dimming. Most custom ROMs run at 60% brightness, locked, or cause PWM flickering at 240hz.
The only successful long-term mod is to flash the "Samba Off" firmware (a modified official PKG that removes the Samba Interactive TV process which consumes 120MB of RAM constantly). Users report boot times dropping from 75 seconds to 42 seconds.
