...but luckily i had a second back up with someone else who was away and unable to give me the seed until today.

I see two issues in storing your seed in this way.

1. The other party can always access your wallet and empty it of any coins.
2. A third party can steal the seed from the person you gave it to and do the same.

Although you might trust that person never to steal your money he might lose your seed, misplace it or simply have it stolen from him.
It is not a good idea to give another person THE ONLY copy of your seed words.

Someone else had asked whether i have any of the addresses saved. I guess i can do that now i have access. Should i do this? If so could you kindly direct me on how to do so?

This isn't strictly necessary, but knowing one of the first addresses generated from the seed, or even better knowing the Master Public Key, can sometimes help in recovering the seed if you know most of it but are missing a word or two. Proper back ups as above negate the need for this step. If you want to do it anyway, open your wallet in Electrum, go to Wallet -> Information, and save the Master Public Key to a file on your computer or write it down, the choice is yours. The Master Public Key allows you to generate all the public addresses for your wallet - if someone else gained access to it they could see every address in your wallet, but they wouldn't be able to access your coins.

the problem with seeds is that there are many different clients and many of them are different from one another usually in the BIP32 path they use. so even if you have your seed you may not be able to recover your keys due to this difference. having one address can give you a result to compare with inside a loop and find the correct path specially when you don't remember the client you used to create the seed.
(that is why i asked him if he had his address in his topic which he was saying he had sync problem not showing his balance)

I have a back up too, i wasnt with it. But youre right, lesson learned, i will keep one accessible.

I travel a lot and wanted one in a permanent location. He provides that for me, though he wouldnt know what to do with the information even if he had you lot on speed dial.

Youre right the least i can do is admit my stupidity. I was using a 12 word seed that was simply not for Electrum. I still have no idea what it was for, but luckily i had a second back up with someone else who was away and unable to give me the seed until today.

This is kinda bad for your security.
What is the main reason for you to entrust the SEED to someone else? On top of that, you never had your own backup of the SEED until yesterday.

He still got your SEED and he can spend your coin whenever he wants.

One last thing. Now i have established access, what should i make sure to back up to avoid this again.

I have written and rewritten the 12 word seed that allowed me access. It isnt stored online or anything like that.

Thanks a million

First of all you should give back to the community by telling us exactly what the problem was. That way we can learn and anyone else who has this problem can also learn from your experience.

Second there is no reason to save the addresses. As long as you have the 12 words you are fine. The reason you were told whether you knew any of the addresses is because it would serve as a check for whether the correct wallet was restored. A check that could be useful if you needed to run brute force recovery tools. However non of that is necessary if you have the seed written down correctly.

What you can do is save the wallet file as well if you care about labels for transactions and addresses. You can do this via file > save copy.

This is the correct course of action. Write your 12 word seed phrase written on a piece of paper and store it somewhere private and secure. Best to do this more than once and store copies in at least two different locations to protect against things like fire or flooding destroying your back up. Obviously, however, the more places you store it in the more chances of it being discovered by someone else. Never store your seed phrase on an electronic device.

To make sure that you have the correct seed backup(Don't forget some address just for the future reference) you need to restore the seed as a new wallet in Electrum then check your addresses if it's correct.

If it's correct you can now save your seed somewhere safe or write it down on the piece of paper. Always make a copy 2 or 3 copies on the piece of paper is good.

Can you recall the original addresses? Do they start with "1", "3" or "bc1"?

Also, you said you've tried to enable the "BIP39" option, right?
If it happened to be a BIP39 SEED, was the message on the left side of the option said "BIP39 (checksum: failed)" or "BIP39 (checksum: ok)"?
Because any of the two will enable you to press "next" button to create the wallet but real BIP39 SEED will display as "ok".
If not, you might have miss-clicked one or changed the order (now or during the 1st wallet creation backup).

It's not bip39 because he says above that there are words that are not a part of the bip39 wordlist.

It just has the application file.

It's useless then, Electrum complies with backward compatibility with the SEED (not BIP39 SEEDs) and it's pretty much the same with the newer versions.
That's only an option if you still have the original wallet file.

No, some of them are not in there.

You did check both lists right? If yes then it's not an electrum seed.

I uninstalled Electrum and plugged in a external hard drive that has the version of Electrum that the wallet was on before.

Does that external hard drive also have a copy of the actual wallet file (not just a copy of the application) on it? If so, make a copy of the wallet file and then try and open that copy with the new version of Electrum.

I uninstalled Electrum and plugged in a external hard drive that has the version of Electrum that the wallet was on before. When i plug that in and go to open the wallet it says "Failed to execute script Electrum"

Not sure if this means anything

Thank you for your response.

This is what worries me, the words arent in there, but at no point did i opt to generate a seed elsewhere. What is this 12 word seed i have? Is it useful for anything? I am very sure i copied it down correctly, multiple times.

If it wasnt generated by Electrum does this simply mean i have lost access to that wallet?

The older versions accepted the words when i checked BIP39 but when i followed that process through (adding a password etc.) there was no balance in the wallet.

Thank you again

This is of great concern:

Quote from: cb327 on May 22, 2019, 05:00:40 PM

some of the words in my phrase are in that big master list, but others arent.

ALL of the words should be in the BIP39 wordlist... Electrum uses only words from this list to generate seeds... it is in the source code. So if you have words that aren't in that list, then you either copied them down incorrectly, or it wasn't generated by Electrum.

Quote from: cb327 on May 22, 2019, 05:46:18 PM

I have retried with older version (3.03 which i think is what the wallet was originally generated with) and 3.01 but they wont get past the synchronising stage..

Did those older versions actually accept the words? Did it allow you to click "next"? If it did and it opened the wallet but was stuck on synchronising, then you should be able to simply open the created wallet file in the new version of Electrum and it should sync.

I checked BIP39 and followed that through. It generated a wallet but the balance was 0.

Thank you again.

Which wallet you currently using right now the Electrum mobile version or the PC version?

Make sure that you are not using any VPN in your Android phone and if you are using PC version make sure that you download it to the correct website it should be https://electrum.org

If you download it on different website URL it's a fake one beware.

Have you tried selecting Options below the seed input box and checking BIP39 there? It shouldn't be required since you generated your wallet using Electrum but it's worth trying out. Alternatively, you can temporary downgrade Electrum if that doesn't work (previous releases).

Hello,

I have this same problem.

I have the seed written down and saved and have entered it many times but the next button remains greyed out.

I have restored this wallet before so i am sure this is the seed phrase! some of the words in my phrase are in that big master list, but others arent. It was Electrum that generated the seed, i am using version 3.3.6

Any help would be much appreciated.

Was the SEED created by Electrum through "Create a new SEED" option or the SEED was created through other tools like iancoleman.io and you used the "I already have a SEED" option to make a wallet using it?
If it is the latter, you cannot use an Android version to restore your wallet because it doesn't support "real" BIP39 SEED.

Usually, people who want to create a SegWit "3" address using Electrum do that.

However, it is possible that the OP has simply got one of the BIP39 words incorrect... there are very similar words in the list... things like kit/kite, kid/kind, keep/keen etc

Thus, it's also possible that OP didn't write the word in sequence, perhaps might jumbled sequence of words.

This is why I don't save my passphrase in my laptop or anything online and just wrote it down in paper and made multiple copies.
Hope you still recover your bitcoin.

The Android Electrum wallet has it's own builtin keyboard that prevents you entering "non" BIP39 wordlist words... Once you type in the first character of a word, ONLY characters contained in BIP39 wordlist words are available to type and you have to select a word from the presented list:

best way is to go on PC and then do that, make sure you check spellings of each word you type on google, typos are common
LIKE color -> colour

it is not safe to enter your seed elsewhere specially online ("on google" that you mentioned). Electrum (desktop version) has the option to show you a preview of the possible words as you type the first 3 letters of each word and that should be more than enough for spell check.

I created a wallet on or near december 31st 2018 with electrum. This was my first time using an electrum wallet and i wrote down everythin that looked important including the public key and the recovery passphrase.
there is some bitcoin in the wallet now and im trying to recover it because the notebook crashed and wont start at all. So Ive borrowed a friends notebook which is running android. I was running windows before.

Ive read other threads concerning this issue but I'm not sure how to solve the problem.
I'm absolutely sure there are only 12 words and that they are spelled correctly.
I'm using the electrum wallet from the google play store downloaded as of today, may 18th.
the next button is greyed out so I cant continue.
the wallet still has the coins in them according to the public key lookup.
Any help here?

make sure you select words not type them, sometimes you add extra space by mistake.
