. I had to swap my wallet to a bigger SD card bc the blockchain has become bigger. Everything went smooth until I wanted to restore the wallet. Typed importwallet /home/pi/Desktop/WalletBackup.dat and it indeed seemed to upload my walletbackup file from the desktop just fine. Alas, nothing happened for days, still everything on zero despite the wallet being fully synchronized and the backup uploaded. Then I thought no problem, I restore my wallet via the privkey. But the privkey has a black square among the numbers and letters, and I donât know how to type that in. Have you ever encountered such problem? Contacted the RDD team, alas no response.
Hi there.
Some questions, to make sure everything is clear:
-
Youâre using Reddcoin Core on a Raspberry Pi, correct?
-
How did you do the restoring/importing the wallet? Where did you âTyped importwallet /home/pi/Desktop/WalletBackup.datâ?
-
To import a private key (privkey), you need to extract it first. So, I assume you extracted the private keys beforehand, and tried to import them?
-
When restoring the wallet, to which location did you restore the wallet? And what was the file name of the file you restored on that location?
And:
- Are you using VNC to connect to your Raspberry Pi?
- Which version of Reddcoin Core are you using?
Â
Â
A lot of questions, please answer as much as possible, post as much information as possible.
Steps for restoring a backup of wallet.dat
:
-
Make sure Reddcoin Core is not running. If it is running, exit/close Reddcoin Core.
-
Go to your âdata folderâ. In this folder, all the blockchain files are saved, and also your wallet file (wallet.dat).
- This folder is located in your âHomeâ directory. It is a hidden folder named â.reddcoinâ (with a dot in front).
Open your home folder in the file explorer, and look in the âViewâ menu to see if you can see âhidden filesâ. - Open the â
.reddcoin
â folder!
- This folder is located in your âHomeâ directory. It is a hidden folder named â.reddcoinâ (with a dot in front).
-
In the â.reddcoinâ folder, there is already a file named âwallet.datâ. Rename this file, for example to âold_wallet.datâ.
-
Now, copy your backup wallet.dat file to the data folder.
- The data folder now should have a
old_wallet.dat
file andwallet.dat
file.
- The data folder now should have a
-
Run Reddcoin Core. The wallet you restored should be loaded.

Let me know if you have questions or need any help.
If you have a password on your wallet, unlock the wallet first before importing private keys.
- Settings -> Unlock wallet -> leave âFor staking onlyâ unchecked (only to import; when staking, do check it).
You can import a private key via:
- Help -> Debug window -> Console => enter this:
importprivkey <reddcoinprivkey>
For example:
importprivkey vrandomrandomsdfjsidjfji2232
Â
You can add a label to your address, for example, to give label âMainAddressâ:
importprivkey vrandomrandomsdfjsidjfji2232 MainAddress
- yes, on a raspberry pi, in fact the staking box from pi sales.
- they sold it with a 16 GB SD a year ago, then my box stopped staking this summer and it turned out there was no space left on the SD, fun fact: turns out the staking box is now being sold w a 32 GB SD bc the blockchain has become too big. I bought a 32 GB SD card from them on which everything was perinstalled, thus changed the SD cards in my stake box and have the latest version of the wallet on it, synced and everything.
- Then put the backup file on the pi desktop as well. Went to the debug window in the wallet. Thatâs where I typed the command importwallet etc. The upload bar showed, went up to 100 % and all seemed fine.
- I ve extracted the privkey from my old wallet with the command dumpprivkey and my receiving address in brackets. That, fortunately, I actually did before I went away for the summer and the wallet went dead / stopped staking on the old SD card. The privkey was displayed, all fine. It has 52 characters including that black square that I didnât worry about then.
- I transferred the backup file of my wallet from my usb to the desktop of the pi after I had put the new SD card into the pi. I only transferred the backup file when everything seemed to be working nicely already, that is surface of the pi looked slick, VNC was enabled.
- I executed the wallet protocol on the pi, synced it, when it was synced, I went to the debug window (console) to type in the âimportwallet commandâ
I canât see much on the screenshot, canât say anything usefulâŚ
By the way: Your current wallet has 0 RDD, correct?
Thatâs correct 0 RDD, no transaction nothing there. The screenshot needs explanation: thatâs the âblack squareâ in the privkey.
EhmâŚ
You extracted the private key before the summer, right? That private key has no black squares, right?
Did you do these steps to import?
- Unlock wallet and use importprivkey. Explained in a post above.
- It can take a while to import a private key, so if the wallet seems frozen, leave it as is, itâs busy importingâŚ
No, thatâs unfortunately the privkey from b4 the summer that already had the black square in it, only I didnât think of it as weird then. Today, I ordered a new / plain 32 GB SD card, was thinking that I could put an image of the old 16 GB SD card on it, then plug that one into the raspberry and see if the old wallet (that was also already running on the latest RDD wallet update) opens on it like it used to, and if I could retrieve the privkey from there one more time. Side note: after the 16 GB SD card wallet had stopped staking at the end of summer, everything still seemed fine except it was not staking since there was no space left, when I looked at the pi again a day or two later (wanting to have another after summer backup and recheck the privkey again b4 putting the new SD from pi sales in) via VNC and then also directly via HDMI monitor connection the pi was black, so another backup or just checking the privkey one more time was not possible.
HmpfâŚ
I myself never had the issue of a black square. Always had a letter/numberâŚ
I assume something went wrong when exporting or copy/pasting the private key.
- Do you still have the 16 GB card (with your old data)?
- Do you have a backup of the wallet? In this case, the backup is a â.datâ file (like: âwallet.datâ).
A backup can be made in Reddcoin Core, using the âFileâ (menu) -> âBackup walletâ option.
Have you ever heard of TeamViewer? Itâs a program that can be used for remote control, so somebody else can help you via the internet.
Would you be willing to let me help you using TeamViewer? I know it is crypto, so I know I understand if you do not want this.
What I would do:
- I see a WalletBackup.dat file on your Desktop in the screenshot.
- I will place this file in the correct folder.
- The steps I will take are detailed here.
Yes, I still have the 16 GB, which is now black when put back in the pi. My guess is that it ran out of space. Thatâs why I was thinking about making an image of it on my PC, then transfer it to a plain 32 GB SD, insert that one and see if â hopefully â- the old wallet opens again and I could dump the privkey again.
And yes, backup files .dat from September 19, April and June 20.
Re the black square - yes rmmphh I thought it was a display error, first I mistook it for an m but when u zoom into it, see above, it is a black square, right? Thank you! I ll keep u posted
Okay, you have a backup file. We can use that to restore the wallet! :).
You can try doing that by yourself, using the instructions I posted earlier. Or I can help via TeamViewer.
And? Any updates? Let me know if you need help.
Hey there, no update as of yet except I ve managed to make an image of the old SD card on my PC. Took about 5 attempts. Will transfer the image to a new, bigger SD card, put it in my PI and see if I can get the old wallet running like b4 and then hopefully retrieve the privkey one more time! I ll keep u posted! Thank you for hanging in there with me.
OkayâŚ
But did you try to use the backup file you have uploaded to your Desktop (the WalletBackup.dat file)?
I have made a video for you:
Steps:
- Make sure Reddcoin Core is not running. If it is, exit/close Reddcoin Core.
- Transfer the backup of your wallet.dat to your Raspberry Pi via VNC.
You already did this. - The file is now on the Desktop of your Pi.
- Rename the file, to
wallet.dat
(all in lower case). - Open the file explorer. By default, it opens on your
'home'
folder.
Your home folder has folders like: Desktop, Documents, Downloads etc. - Now, make hidden folders visible. You can do this via âViewâ -> âShow Hiddenâ (or by using CTRL+H).
- You will see some extra folders/files appear. One of those folders is
'.reddcoin'
(with a dot (.) in front). - Open the
.reddcoin
folder. This folder is the âdata folder of Reddcoin Coreâ. - In the .reddcoin folder, you will see a
wallet.dat
file. Rename this file to something else (for example: old_wallet.dat). - Now, copy the wallet.dat on your Desktop (your backup) to the .reddcoin folder.
- Start Reddcoin Core.
- Check if your balance is restored/as expected.
And, how did it go? Did you see the video and instructions above?
