Installation on Nano X using installer_s.sh fails

[valentinbud]

Hello everyone 👋.

I am trying to install the latest v2.3.1 version on a Ledger Nano X from a MacBook.

I have downloaded installer_s.sh from v2.3.1 release page .

I have ran the following

pip3 install ledgerblue

~/Downloads/installer_s.sh load

The device has an older version of the app already installed, v1.8.2. The firmware is at 1.3.0, latest, as reported by Ledger Live. Development mode is enabled.

The error sounded like the installer doesn't have the correct targetId value setup.

I have found here the following snippet of code to check the id of the device

I have updated the installer_s.sh file with the above targetId value

- LOAD_PARAMS="--tlv --targetId 0x31100004 --targetVersion=2.0.0 --delete --fileName bin/app.hex --appName Oasis --appVersion 2.3.1 --dataSize 8256 --icon 0100000000ffffff00ffffffffffff5ffcaffbaff5d7ebd7ebd7ebd7ebaff5dff53ffaffffffffffff "

- DELETE_PARAMS="--targetId 0x31100004 --appName Oasis "
+ DELETE_PARAMS="--targetId 0x33000004 --appName Oasis "

Running the installer again the error changed.

Am I missing something? What can I do to have the v2.3.1 app installed? Thank you.

Nano X devices are locked and do now allow sideloading. You can only use unreleased firmware in Nano S device and definitely it is only recommended for testing/development purposes.

Thank you @jleni for clearing this up for me. I'll wait for the v2.3.1 PR to get merged then.
