Hi Guys, Seek your help regarding my issue with Lenovo B490 Bricked after update BIOS. The issue before i updated the BIOS was failed to enter Setup and based on my research that BIOS shortcut key is locked by lenovo(altered). Here why i was done before the system bricked. 1. I tried to update BIOS to latest one from Lenovo website. 2. New BIOS cannot be installed before i update to advised version. 3. Download and flash BIOS using MS-DOS, showing flash bar but the result was failed. 4. Restart the system and it couldn't POST. Symptom: - LED Power Button: On While then off, Looping. - Try to Fn+R: ON more than a second, like 3-5 second, after that On While then off, Looping. - Minimum POST w.o memory: Beep No Memory. I suspected the issue w. BIOS Corrupted. Tried to Recovery BIOS: 1. Download BIOS latest and advised update by lenovo. 2. Recovery using Lenovo.Phoenix.Crysis.Tool 3. On this point i believed the disk i created was completed and able to use. 4. Fn+R, LED Flashdisk showing read activity like 3-5 second but it turn off and continuing LED On While then off, Looping. Based on my finding this system got 3 different BIOS and i also tried used all the BIOS 1 by 1 with result still failed. Next action: Re-flash BIOS using Flasher tools (Ordered online). I'm still not sure what BIOS file need to flash when the tools arrived, New BIOS / else? (Please suggest) Seek ur help or for any suggesting for my issue to solved my problem. Thanks !
It worked. Not exactly as described in the supplied instruction though. I used this version Instruction tells to flash same version of original bios first and after reboot use the patched one. When attempting to flash patched version afterwards I only had a message that bios version is the same, flashing is not needed and will not continue. I googled a little and found that some guys tried running WINUPTP.EXE -s. So I tried. For a few minutes mouse pointer was lagging badly while updater performed it's job without any messages or windows. Then lagging stopped and after a few more minutes and a check for running processes in Task Manager just to be safe, I shut down Windows, plugged in wifi module, turned the laptop on and it started flawlessly. Thank you for your work and for the quick response !
now not downloadable again, could you please upload it once more? (I have 83et80ww 1.50 version but it may be some later version, I can update) By the way flashed your bios 1.49 to my t520 - works, thanks!
