Lenovo B490 (20205) BIOS corrupted. No more display. Help!

Hello guys!

                   This is Kamesh. And I own a Lenovo B490 (20205) laptop that was provided by Govt. of TN. I had the B460 before. I tried to update the correct BIOS on B460 that was downloaded from Lenovo IN site. And it worked perfectly without any problem. The Govt. of TN logo disappeared and the normal Lenovo Logo appeared on B460. So this is fine.


Now that I have the B490 and I tried the same. I downloaded the BIOS update from Lenovo IN site by inputting my Laptop serial number and it showed my laptop as Lenovo B490 which is correct. So, I saw that the BIOS update was available. I decided to download and install it. I had Windows 10 64 bit in my Laptop. I installed it and I started the BIOS update it showed me the usual warnings such as Connect AC adapter. I did all the things (I've previous experience of updating the BIOSes). So, it started to flashing the BIOS and after some time the laptop didn't turn on. Found out that the BIOS didn't post. The screen was complete black. Now that my Laptop won't post.


I tried many methods on internet to recover the BIOSes. I tried the WinCrisis.exe method and found out that it works only with Phoenix BIOS. And I have Insyde BIOS.


Please let me know if you can help me with this.


How can I recover the BIOS and reset it to normal state. I have previous experience of BIOS update failures too and I recovered it successfully. It was an Acer laptop. It was so simple.


PS: Recently I got the BIOS backup from my friend's laptop. Let me know how to recover.


Please help me here.


I've been trying so much. Couldn't find any solution.


Found out my warranty expires on 05 Sep, 2016. And today's date is 04 Sep, 2016. Today is Sunday and Tomorrow is a local holiday. I couldn't ask them. It's holiday today at Service Center. Tomorrow could be local holiday for them.


Please help me!
