May 20, 2019, the ampere is  redefined such that the elementary charge (charge of electron or proton) would be equal to 1.602176634 × 10−19        

  ampere now  μ0 is no longer equal to 4π × 10-7 weber per ampere-metre and must be experimentally measured. However, [μ0/4π × 10-7] is 1.00000000055

  Requirements

• root access.
• pv, tar and cgpt packages/binaries 

STEPS::

1. download recovery image from https://cros-updates-serving.appspot.com/ 

2.download and extract brunch from https://github.com/sebanc/brunch/releases

sudo bash chromeos-install.sh -src rammus_recovery.bin -dst /dev/sda

 it will wipe /sda completly 

for dual boot :: 

see readme in github brunch 




 win+x run cmd/powershell as admin 

  wmic path softwarelicensingservice get OA3xOriginalProductKey

##this gives oem key in bios/uefi i.e key that came with hardware

run notepad :: pasta
