first find when we have actual state found give big timeout because it can take a bit of time

$ cast rpc --rpc-timeout=9999999999 --rpc-url=localhost:3545 debug_getAccessibleState $(cast
to-hex START_BLOCK) $(cast to-hex END_BLOCK)

where START_BLOCK is the beginning the search and END_BLOCK is the end of the search

Get the block hash and rewind the chain to it

The instructions were tested on a Lenovo X1 Carbon 5th Gen (X1C5) on Arch Linux but should be applicable to other Lenovo models and Linux distributions.

BACKUP YOUR DATA! I created a bootable Ubuntu Image like this:

$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.

then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:

Creating bootable Linux USB using Mac

CentOS, Ubuntu, Slackware, etc. Whatever Linux-based OS it is, you can create a bootable USB for it by using a Mac.

1. Prepare the .iso file

Download it, copy it, whatever it takes to prepare that Linux-based OS .iso file

2. Convert the .iso file into a .img.dmg

Upgrade to at least 0.8.4

Using newer compiler versions and the optimizer gives gas optimizations and additional safety checks for free!

The advantages of versions 0.8.* over <0.8.0 are:

Safemath by default from 0.8.0 (can be more gas efficient than some library based safemath).
Low level inliner from 0.8.2, leads to cheaper runtime gas. Especially relevant when the contract has small functions. For

Build in CMake with these params:

CMAKE_CXX_FLAGS:STRING= -fsanitize=address  -fsanitize=leak -g
CMAKE_C_FLAGS:STRING=-fsanitize=address  -fsanitize=leak -g
CMAKE_EXE_LINKER_FLAGS:STRING=-fsanitize=address  -fsanitize=leak
CMAKE_MODULE_LINKER_FLAGS:STRING=-fsanitize=address  -fsanitize=leak

Which can be done with:
