Unable to import old wallet

I invested in some zcash in the past

Now I find that the wallet I used in the past is no longer developed

The last wallet I used was downloaded through this domain name



I have a backup file, how can I import it to an available wallet?

I tried to import “ZecWallet FullNode” but failed.
Or my import method is incorrect
under debian

What kind of failure do you see when using Zecwallet?

Can you explain in detail?

Prompt me to check the log. Faced with the large log file, I lost my interest in checking it. I am not a developer.

Pass “./Zecwallet.Fullnode-0.9.22.AppImage --no-sandbox arguemnt”
I have successfully run it under debian

Now I just want to import past wallet backups.

You would need to rescan for each wallet by issuing zcashd -rescan

I copied and pasted past data, But the format is wrong

This is the backup file, the version shown inside

Wallet dump created by Zcash v1.0.10-1-eabd83a-dirty

Are you getting any error after issuing zcashd -rescan from the command line after installing latest Zecwallet Fullnode?

If so, what error?

I am confused why do I need to execute “zcashd -rescan” when importing wallet backup

At present, I can only use the AppImage package to run normally

In the past, I encountered a prompt to execute zcashd -rescan, but the same error still appeared after execution

Since it takes a long time to synchronize the blockchain, I don’t want to test other installation packages.

AppImage is the only one that successfully synced the blockchain after I tried it for a long time

Please tell me how to import zcash4win backup files

The zcash4win backup file seems to have information that ZecWallet does not seem to recognize, such as time

My English is not good, please forgive me if there is a vocabulary error

If “zcashd -rescan” is executed, does it mean that my backup file needs to be placed in a specific location? Can be recognized by “zcashd -rescan”

Do you have the wallet.dat file from Zec4win?

That is all you need, don’t copy anything else.

  1. Start a fresh ZecWallet Fullnode and let it fully sync 100%. (You can choose fast sync option)

  2. Stop ZecWallet Fullnode and replace new wallet.dat file with old one from Zec4win.

  3. Restart ZecWallet Fullnode with -rescan so it will search the chain for your funds in the wallet.dat

Glad to see such a reply.

The problem is that I now start the wallet like this

./Zecwallet.Fullnode-0.9.22.AppImage --no-sandbox

Should I change it to start like this

./Zecwallet.Fullnode-0.9.22.AppImage --no-sandbox -rescan

My Zec4win backup file is human readable, ZecWallet’s default wallet file is not readable, I renamed the backup file to wallet.dat, compatible?

I just tried again “Zecwallet_Fullnode_0.9.23_amd64.deb”

Tested under debian10

Can you check debug.log and db.log for errors? There should be something in the last 20 lines.

Also, it would be very helpful to run under gdb.

$ gdb zecwallet

Type r and press enter.

After it crashes, type bt and press enter. Then post the backtrace here.

If you’re on debian, you need to start with --no-sandbox. This is a debian-specific issue.

To rescan, you need to pass the argument to the zcashd binary. If you installed the .deb, you can just run zcashd --rescan from a terminal, which will start the zcash daemon. You can then start zecwallet, and it will connect to the running daemon.

Can I run “zcashd --rescan” like this “./Zecwallet.Fullnode-0.9.22.AppImage --no-sandbox -rescan”

I am confused about the testing environment before the release of zecwallet. Why did the developer not encounter the problem I encountered

Aditya is the ZecWallet developer and answered above:

Oh, I am confused, I pointed out above that I can only run normally “./Zecwallet.Fullnode-0.9.22.AppImage --no-sandbox”

But what Aditya told me is the .deb method

I need to know how to run “zcashd --rescan” using .AppImage

I think the reason why zcash has not been widely used is because ordinary users cannot run wallets.

I planned to invest when zcash was public, because there are many difficulties in running the official wallet of the wallet. Until after zcash4win appeared.

zcash4win is very good. It is very easy to run and has never encountered any problems. I am very confused why it disappeared.

If the zcash wallet is as easy to run as other mainstream currency wallets. Its usage rate and price are more than that.

It’s much simpler and faster if you just use ZecWallet lite and don’t have to download the entire blockchain :slightly_smiling_face:

I mentioned earlier that I used the .AppImage package to run normally and synchronize all the blockchains. I need someone to tell me how to import zcash4win backup files
