Hi @olafwriggers

This is a known issue that being handled by the ledger team and we are waiting for the response.

Here are 2 tricks that may help

1. Change USB slot, this trick worked for several users;
2. Send a transaction with small amount before sening the large one;

This error is still being processed and I will ping here once it's fixed.

[olafwriggers]

both tricks don't work for me.

I'll wait for your ping, thanks

Hi @Panthers14 The Ledger team is still working on it, they treat this high priority because RGB++ is under the spotlight in the BTC ecosystem.

Just checking in to see if any progress has been made on a solution for this issue.

No, they cannot handle this, and we take over the maintenance of ledger app this month.
We are going through the code and fixing issues we've found during the code skimming. We will give priority to this issue when we are familiar with the codebase.

Issues we found and are fixing now

• Incorrect address in come case: Debug timeout of LedgerHQ/app-nervos Magickbase/neuron-public-issues#406 (comment)
• Outdated address format: Multisig addresses are different between Neruon and Ledger when signing with the hardware wallet Magickbase/neuron-public-issues#413

@olafwriggers @Panthers14 I got the logs, but found that only the logs are not enough to locate the exact error, can you export the transactions and send them to neuron@magickbase.com?

[Keith-CY]

We are going to update the nervos-app on ledger device for straightforward error messages instead of unknown error
