Getting started

From the project's README ("Quick start"):

git clone https://github.com/nimrc/sony-a7c2-fl23-linux.git cd sony-a7c2-fl23-linux ./a7c2-fl23.sh # guided: setup -> prepare -> install

Or step by step:

./a7c2-fl23.sh setup # download and verify the toolkit, create the Python env, install the udev rule (no camera) ./a7c2-fl23.sh prepare # back up and check (no program writes) ./a7c2-fl23.sh install # install (writes to the camera) ./a7c2-fl23.sh verify # check after the cold start (optional) ./a7c2-fl23.sh restore # restore the official programs from this body's backup ./a7c2-fl23.sh status # show workspace state and the camera's USB identity

The script's messages are in Chinese. Data lives in ~/a7c2-fl23/ by default:

DirectoryContents
toolkit/Upstream toolkit and its Python environment
work/Workspace: this body's original programs, settings backup and operation journal. Restoring depends on it
backup/Second backup copy. Put it on another disk with A7C2BACKUP=/other/disk/path
logs/Full output of every run and evidence from failures

Risk and recovery

Brick risk
High
Reversible
Yes
Requires opening the device
No

From the project's README ("Restoring the official firmware programs"):

Select ST on the camera, do a full cold start (shut down, remove the battery for 10 seconds, power on), then connect:

./a7c2-fl23.sh restore

Restore only works with the work/ directory of the same body. Do another cold start afterwards.
