Using the new official unlocking method, SL04 of any firmware version can be upgraded for free, This upgrade will use a simpler and more convenient operation method. Please pay attention to the announcements on our website, where download notifications will be posted.
In addition, the development of the SL04 box’s automatic firmware update program is currently stuck in the final stage. The chip manufacturer originally promised to provide the chip burning protocol and IAP SDK. But now, the chip manufacturer has changed their mind at the last minute, fearing protocol leaks, and is unwilling to provide the burning protocol and IAP SDK, At present, we can only use the chip manufacturer’s own burning tool.
Currently, we can only reverse-engineer the burning protocol, Please be patient, in due course, this problem should be resolved.
If you cannot wait, you can send the SL04 box back to the manufacturer for an upgrade.
Note: The latest firmware version is currently V6.7 (2026-05-25), We recommend waiting until firmware upgrade V6.8 before sending it back, as V6.8 is planned to include new features.
