Hello,
I have an Electrum wallet on my laptop. I lost that charger so I won't be able to get in it for a month or so.
So I have a hire laptop from my school. I want to transfer the wallet with the long code I wrote down, but I can't click next when I typed them all. I also noticed that I only have 12 words... Am I screwed? I do have a date stamp.

Kind regarts,
Papi

update to the latest version and try again. if that still doesn't work (it should work) then install electrum version 1.9.8 from here (https://download.electrum.org/), restore your wallet, then update to the latest.

Oke, I will try, thank you!

Are you sure its electrum and not multibit HD?

Yeah I am sure. I did have a Multibit HD so maybe thats where the datestamp is from. I tried downloading the old version and I connected my wallet, but I can't upgrade to the current version? I tried downloading it from the site but it doens't work?

you can't upgrade? does it give you an error message when you try to install? also what's you OS? people are having issues installing on windows XP.

Any errors or just the same not accepting the seed? Can you get it to work with the old version?

I deleted everything, and downloaded the new version, but then I am back at where I started, that I can't click next.
I will try the other methode again, hope it works..

If you can get any version to work, you could export the private keys. That would give you more options as they are not limited to be used with electrum.

Hello,
It downloads, no errors, but when I start it it just won't start. Currently running windows 7.
I downloaded the new version like I said but then it doesn't work anymore.
I will try to export the private keys.

I got so far I am in Electrum 1.9.8, typed my words code, but it doens't connect. So I can't check if the payment history is correct.

I got connected! But now the problem is, it says that my balance is 0 mbtc.... And that is not correct...

is it showing the right addresses and transactions? check any wrong addresses and transactions on block explorer and see if they match. if the block explorers shows your correct balance and transactions then you're fine and can just import the private keys to some other wallet.

also on upgrading electrum (if you want to try again): save the copy of your wallet and export your private keys(!), uninstall electrum, then try to install the latest version again (if you get a "permission" error message, run it as administrator) and open the saved copy of your wallet from there.

The problem is that in this version, I can't find my address anywhere?
It is like my code doens't work?
By receive there is no address.

looks like you didn't connect correctly. the a little ball icon beside the seed icon and it should be green if you're connected to the network. if it's already green but you still don't see any address, click the ball icon, uncheck "select server automatically", and try them one by one.

I tried all of them. With some of them I connected (green ball) but it did not show any address or transaction history.

sooooo apparently electrum 2.x.x generates 12-words seed AND 13-words seed. and looks like you only started using electrum in february so that means you used 2.5.4.
install version 2.5.4 (or any 2.x version should do) and restore it from there.

I just downloaded the 2.5.4 version and it is the same story as the latest version... I type my words but I can't click next...

Are you 100% sure you are typing the seed correctly? There is a checksum to detect typos. A single typo in the seed will prevent the "next" button from lighting up.

BTW, older versions of Electrum did not have the checksum, so if you type the seed wrong it will seem to work, but the addresses will be all wrong and you won't see your history/balances. That is why they added the checksum in newer versions.

I could try a brute force attack on the seed to look for a typo if Pappiony wants. Would require the seed, an address that belongs to the seed and an address where I should send the coins to if it was a success.

Hello,
If you can that would make me very happy :)
I tried it over and over so typo seems unlikely
Only problem is I don't have my address because thats on the laptop with no power :'(

If you open the wallet file with a text editor you will see something like this:


The first kind is an unused address. The second kind is a used one with a TX ID and the block (here 398218) the TX was confirmed. The address with the lowest block would be good, because the programm works faster if I only have to check a fee keys for each possible seed. E.g. if you could find one of your first 5 addresses (if you remember) that would be nice. If not, I will check the first 20 on the first run.

Sorry, I really can't remember. I just did like 4 transactions so I don't know it...
What else do you need from me?

The script[1] needs one of the following

#1 master public key
#2 address
#3 wallet file

to test the seed against. Any chance to access the data on the laptop even though it has no power?

Sorry, thats no option then. I need to wait till I have a charger (which cost 100dollars  :o :o :o). Thanks for your responses, but I can't reach the address or anything.

No problem, good luck with your search for a solution. You should probably migrate to a fresh wallet once you can access your coins again. Its odd that the seed is not working.
