Hi, 

I am very novice to this. I recently got my Lenovo Y 50-70 Nontouch Model bricked. This occurred due to the ubuntu 17.10 bug. I had also wiped the data from my HDD and then I was unable to save changes to my bios setting. Because of this, I am now not able to boot from USB or a new HDD.

A method mentioned in another forum was to reflash your Bios using a CH341A programmer and a SOIC8 SOP8 test clip. I would like to try this method to get my Laptop back to life. To do so, could anyone help me on where to locate the bios chip on the motherboard and where to find the default BIOS file to reflash the chip.

I currently have a BIOS VERSION: 9ECN33WW(v1.16)

I already purchased a CH341A programmer and a SOIC8 SOP8 test clip from eBay. 

Any help would be appreciated. 
Thank you in advance.

Hello! I am a newbie and I have just started googling today about overclocking and found this site. Figured I'd have to mod my bios in order to achieve more than +135Mhz to my GPU Core clock. Can you guys help me how to do this? This would be the first time I would be modding a bios, so a step by step would be appreciated. Also I'd like to know how to donate here.

Hey
please unblock my bios
How to upload it if you can know?
And how to restore an old bios if something went wrong, in case something would happen?
