[TUTORIAL] how to unlock hidden tabs in lenovo g50-80/Mod lenovo g50-80 bios
#1
First of all wants to thank dudu ,member of this group to help me in all odds..I m giving all the images in attachements


1. you will have to buy these components
 a) ch341a programmer
 b)SOIC8 SOP8 Flash Chip IC Test Clips
you can buy these item from ebay or banggood.

2.now disassemble the laptop..I'm giving you the youtube link for this ..the video is of lenovo g50-70 exactly same as lenovo g50-80
https://www.youtube.com/watch?v=F9C8XZMotDU
3.now the next step is to find the bios chip which is written as uc3 bios chip number(A1h1512) at the backside of motherboard..I'm giving the pic of bios chip in attachements


4.Now the next step is to plug the programmer in another pc or laptop and install required drivers..link for software
https://mega.nz/#!uJtTgAxC!r0ys8c-DlST8O1mSNpHjOTTCvNEsqFVi2Muf_1UCnh8
when you extract all files then install driver and run ch341.exe  as administartor
5.now connect the clip to the bios chip..the dot on the chip is first pin.

6..open ch341a software and click detect.
the ch341a will not auto detect this bios chip as it is latest chip..so you will have to manually select the chip..click on manufacturer and select gigadevice and name as GD25Q64 like this

then click on read it will take 4-5 min and then click on save and save the bios file..
7..now you have to make thread in this group and send file to senior member..dudu helped me you can ask him also and dont forget to donate him.
8.then he will or anybody who is helping you send the mod file..now you have to erase your chip before programming the chip.then select the mod file and click on program ..this will take around 10-15 min when programing is done assemble the laptop and check whether bios is unlocked or not...dont panic if blackscreen comes while booting the laptop..keep the laptop on for 4-5 min it will definitely boot up..if its not booting up program the chip again and make sure connection are tight while programming...
