Lenovo has withdrawn a recent BIOS update for the original Legion Go handheld after a growing number of users reported that installing the firmware left their devices unusable with black screens.
The update in question, version N3CN42WW, was released to Lenovo’s support website in mid-June with a brief changelog intended to resolve power button and standby issues. However, reports on the r/LegionGo subreddit and handheld gaming communities began surging as owners experienced black screens, faulty power cycles, and unresponsive hardware immediately following the update.
According to community reports, the issue specifically impacts original Legion Go models powered by AMD’s Ryzen Z1 and Z1 Extreme. The firmware update was not automatically pushed through Windows Update or Lenovo’s Legion Space software. Instead, it required users to manually download and execute the installer directly from Lenovo’s official technical support website.
Lenovo’s Response Regarding the Update
In a statement provided to Cloud Dosage, Lenovo officially acknowledged the issue and confirmed the temporary removal of the firmware update:
“Lenovo is aware that some Legion Go devices may experience a blank screen during installation of BIOS version V42. BIOS V42 was not distributed through Windows Update or Legion Space, and Lenovo has removed the update from its support website while we continue our validation work. Users who have successfully completed the V42 update should not need to take further action at this time.”
For users whose devices encountered a blank screen during the installation process, Lenovo provided a specific workaround:
“If a device encounters a blank screen during V42 installation, users may try pressing and holding the power button for approximately 10 seconds, waiting approximately one minute, and then powering the device on again. If the device does not resume normal operation, customers should contact Lenovo Support for further assistance.”
The company added that it “continues to evaluate and validate future BIOS updates for Legion Go.”
Prior to Lenovo’s response, community members voiced concern regarding out-of-warranty repair costs. Handheld owners with active warranties reported receiving motherboard replacements free of charge. While users whose devices fell outside Lenovo’s standard warranty period claimed customer support initially quoted upwards of $250 for motherboard replacements.
For current Legion Go owners, community moderators advise against attempting to run the V42 installer. If your device is currently operating normally on version N3CN40WW (or if V42 installed without issue), Lenovo indicates no further action is required. It is to remain seen if Lenovo publicly acknowledges the issue on their social channels.
