Bitcoin Gold is now accessible on the Ledger Nano S. Hooray!!!!! The software for the Ledger Nano S is available, but I don't believe their tech support is actively supporting it as of this post. So use caution. Here is how you can access it.
Step 1 ) Verify that you have Ledger Wallet Bitcoin Chrome app v.1.9.9
Step 2) Verify your Ledger Nano S firmware is up to date v.1.3.1
Step 3) Install the Bitcoin Gold app on your device via the Ledger Manager
Step 4) If you do not have room on the device, simply delete one of the other apps.(don't worry your coins will be safe, just re-install app and they will be there)
Step 5) Launch the Ledger Wallet Bitcoin Chrome app on your computer
Step 6) Launch Bitcoin Gold app on your ledger device
Step 7) Click on the "BTG split tool"line on the chrome app (near the bottom)
Step 8 ) Select either legacy / segwit chain depending how your wallet is set up.
Step 9) Let the app sync - This will take a few minutes.
Step 10) Viola!! There is your Bitcoin Gold
Step 11) Now you can either hold your coins in this wallet or send them to an exchange.
Replay protection has been enabled so your original BTC is safe.
**Be aware that one of the complaints about BTG is that it is unstable. So there may be risk associated with moving it around. Please understand the risks and exercise caution.
Cheers
BTW: Ledger Wallet Bitcoin Chrome app has changed to v.1.9.10
Problem: There is no "BTG split tool" line on the chrome app showing up.
I did the whole procedure but at the end when I enter in BTG I have 0 BTG. I had some BTC before, while and after in Ledger Nano S at the time of the fork (I did not move them).
I miss something?
EDIT: solved.. I did refresh page and voilà there were my BTG
