If you arrived at this page searching for , there is a strong chance you actually own a Skyworth 55E381E (or a closely related model like the 55E381S or 55E386E). This is a 55‑inch Full HD (1920×1080) smart LED TV that was widely sold in the mid‑2010s.

That version specifically addressed a “slow MHL detection” problem and is generally more polished than the original VER01.00. If your TV is a 55E381E, it is likely compatible with VER01.01 as well—but always verify with the manufacturer before flashing.

At this time, no public release of a VER01.02 or newer version exists for the 9R20 platform. If you find a website offering a “latest” version beyond VER01.01, treat it with suspicion; many third‑party ROM sites repackage the same old files.

This comprehensive article will dissect the keyword, provide actionable steps for updating your firmware, compare the top stable releases, and offer troubleshooting tips to ensure your THV55381 operates at peak performance.
