'Account not registered on blockchain' error when recovering from a Secret key (HEX code) backup

Recovering a Channels app account from a Secret key (HEX code) backup cannot be completed with ‘Account not registered on blockchain’ error.

Cause

A Secret key, or a HEX code backing up a Channels app account, is a 64-symbol code presented in 8 blocks 8 symbols each.

When saved from Channels app screen, it is presented in two columns with numbered blocks, indicating their sequence.

When copied and pasted, or sent via e-mail the code is presented as a string:
262b7e08 ade9fc59 69e1ad45 b39fe4a9 262b7e08 ade9fc59 69e1ad45 b39fe4a9

But when recovering an account from backup, there is a two-column unnumbered form to enter the code to:

It is therefore easy to enter the code in a wrong sequence, e.g. 1-3-5-7-2-4-6-8 instead of 1-2-3-4-5-6-7-8, which is a typical reason a Secret key (HEX code) cannot be associated with the respective ID on EON blockchain and hence is not accepted, resulting in app returning the 'Account not registered on blockchain' error.

Solution

  1. Make sure the sequence you enter the Secret key (HEX code) in is right;
  2. If previously saved, use a QR code based backup to recover your account.
