Lenovo Legion Go gaming handhelds are reportedly being bricked by a BIOS update. According to reports, installing the N3CN42WW update results in a black screen and systems not booting correctly.
It's not clear how widespread this issue is, but I suggest holding off on installing a BIOS update on your Legion Go until Lenovo has clarified the situation.
The problem affects the original Legion Go (often called the Legion Go 1 by fans), including both the Z1 and Z1 Extreme models.
In some cases, the Legion Go failed to boot immediately after the BIOS update was installed. In other cases, the failure occurred later.
Some users have said the performance of their Legion Go has gotten worse over time, such as the controllers not working.
Several Legion Go owners have reported issues on Reddit. The mods at the LegionGo subreddit shared the following:
"It has come to our attention that some of the Z1E and Z1 versions are being bricked when updating to the latest BIOS that was released on June 17th, 2026.
Please do not update your devices unless you are willing to assume all risks. We the mod team are trying our best to understand and get help on this."
They also asked people to share if they've run into the same issue.
Reddit user mherold11 said they reached out to Lenovo support to have their Legion Go repaired. They were told that fixing the gaming handheld would be a chargeable repair since the device was out of warranty. The quote for repair was €237.16 (roughly $273.81).
Other people in that same Reddit thread said their Legion Go gaming handhelds were repaired at no cost when still in warranty.
One Reddit user had luck performing their own repair, but that fix was complicated and is not recommended for general users.
This is a developing story and we do not know the extent of the issue. If you have a Legion Go and have been affected by the issue (or have upgraded and not run into the problem), please share with us through the comments below and reach out to Lenovo and the mods of the LegionGo subreddit.
