How to get Ledger Nano X firmware `1.2.5-1.5` for NervOS? #164

I followed the tutorial and tried the Ledger Nano S and it works. However, the latest firmware version of the Ledger Nano X is 1.2.4-4, and if I try to install hw-ckb-app on this firmware version, I get the following error:

Traceback (most recent call last):

Hello! Unfortunately the Ledger Nano X firmware doesn't allow you to sideload an application onto the device. "Sideloading" is the term used anytime you load an application without Ledger Live. See the note at the bottom of this section of the docs - https://github.com/obsidiansystems/ledger-app-nervos#ledger-app-installation

If you'd like to use the app on the Nano X you'll unfortunately have to wait until it is available in Ledger Live. Ledger distributes development Nano X devices to teams building apps, which is how we've gone about making the app.
