FAQ
TL;DR: Since 2021, exactly 0 official .bin firmware files have been released for WIWA H265 ("It's very risky" [Elektroda, gumisie, post #20039405]), yet community-shared builds like v5.2.2.3 (2025) boost channel count by up to 20 % [Elektroda, java77, post #20414067] Owners should match the HW ID (e.g., 2.1.RC20.4.1UU) before flashing or risk bricking.
Why it matters: A mismatched file shows "INVALID SOFT" and can permanently disable the tuner.
Quick Facts

Where can I get official firmware today?
WIWA stopped publishing official .bin packages after mid-2021 [Elektroda, gumisie, post #20040716] The only reliable âofficialâ source is to e-mail serwis@wiwa.info.pl with a photo of your HW/SW screen; they reply with the last supported build [Elektroda, sleszek1, post #21130220]
What is the latest build for H265 / H265 NEW with HW 2.1.RC20.4.1UU?
Community members have shared v5.2.2.3 (dated 2025-02-25); it flashes successfully on H265 NEW units with the identical HW ID [Elektroda, blondynek102, post #21570183]
Which file should Mini LED owners use?
Use upgrade_MINI_LED_V5.2.1.95.bin. It installs cleanly after factory reset on Mini LED HW 2.1.RC20.4.8UU [Elektroda, czarny_alibaba, post #21332053]
How do I update via USB without bricking?
- Format a â¤32 GB pendrive to FAT32. 2. Copy the matching .bin to the root. 3. Menu â System â Software update â USB â OK, wait for auto-reboot [Elektroda, 2Tom, post #20824372]
What if I see âINVALID SOFTâ?
The file is for another hardware revision. The tuner rejects it within seconds and keeps the old firmware [Elektroda, dzg4, post #20740946] Download the build whose filename contains your exact HW string.
Can I update over Wi-Fi instead of USB?
Yes, but only models with built-in Wi-Fi or a MT7601 USB dongle show âUpdate via Internetâ inside Adapter Applications. Boxes without RJ-45 need the dongle to get a network link [Elektroda, gumisie, #20039330; CichyStaszek, #20967303].
What are the risks of using unofficial firmware?
Wrong firmware can soft-brick; recovery then requires a programmer such as CH341A to rewrite flash manually [Elektroda, gumisie, #20039405; 21577055].
My decoder reboots showing âbootâ repeatedly. Fix?
Continuous boot loops often trace to aging electrolytic capacitors in the power stage; replacing bulged caps usually restores stability [Elektroda, gumisie, post #21228275]
After update I receive 15â20 % more channelsâis this normal?
Yes. Users reported noticeably higher tuner sensitivity after v5.2.1.56, gaining several multiplexes (â20 % more channels) [Elektroda, java77, post #20414067]
Picture still pixelates after flashingâwhy?
Most drop-outs stem from signal quality jumping below 65 %. Check antenna alignment, eliminate LTE interference, or reduce amplifier gain to stop quality swings from 0â90 % [Elektroda, Lukas6432, #20826899; sq3evp, #20827283].
Can I downgrade if the new firmware removes 1080p?
Yes. Flash the earlier v5.2.1.95 through USB; the loader allows downgrades as long as HW ID matches [Elektroda, blondynek102, post #21570183]
How do I back up my current firmware?
Solder clip the SPI flash, read the 8 MB image with a CH341A, and save the .bin before any experiments. âA quick dump avoids permanent loss,â an expert notes [Elektroda, gumisie, post #21577055]
