Electrum wallet stay on "synchronizing" last few days

[HI-TEC99]

If this not help there is a possibility that some file in Electrum folder is corrupted,so you should try to delete blockchain_headers file in Electrum folder.It is located on  C: \Users\YourUserName\AppData\Roaming\Electrum\wallets (or %APPDATA%\Electrum\wallets) but to see appdata you need to click on File - View - Folder Option - Show Hidden Files(in Windows)

A faster way to open the hidden folder containing the blockchain_headers file is to click the windows start button, then copy and paste the line of text below into the search box that appears, then press the enter key to open the folder.

%appdata%\Electrum

This is what your search box should look like after you have copied and pasted the line above into it.



Deleting the blockchain_headers file fixed the problem for me.

Thanks for your help!

"Deleting the blockchain_headers file fixed the problem for me." - if I delete this file, will this transaction appear in my wallet and balance? Because, as I said, now this transaction is verified and with amount +0.
Now my wallet is working and all other transactions are verified. Just the last one is verified and with amount +0.

Like I said earlier I was under the impression that this was an old bug that had been fixed which why is partly why I recommend upgrading rather than this, but it's worth giving it a go.

It is possible that with deleting of this file your problem could be resolved,but it is not 100% that will succeed in your case.There is a possibility that another file is corrupted also,so only solution would be to uninstall Electrum and manually delete all files in Electrum folder on the path which we mentioned earlier.

As long as you have the correct seed for your wallet there is no danger that you will lose your coins,so check your seed by clicking on symbol right next to the green dot and enter your password(if it is protected)then when you are 100% sure it's completely correct you can try to do some of the above procedures.

Hi again, friends,

yes, I posted my question there also, because I am trying to find the best solution of my problem. The transaction's amount isn't small for me. I worked hard for it and don't want to lose it.
 I got 2 blockchain_headers file: blockchain_headers and blockchain_headers.tmp. and don't know which one I should remove from the folder.
Thank you in advance for your help!

I think you should try to solve your problem with clean install of Electrum,as I suggested in post above.It means uninstallation of Electrum program and deleting of all files in his folder.Then download latest version and restore from seed.

Regarding blockchain_headers file,I just check and have only 1 file,no tmp.,but you should delete both,it will not harm your wallet in any way.After that just start 3.0.6 version of Electrum and give it some time to sync.File is about 40 MB,so time for sync will depend of server you are connected and your internet speed.

Thanks for the reply!
If I understand correct, .tmp mean, that the blockchain_headers file isn't full downloaded.
I am scared to unistall the wallet and to restore it from seed, because I just checked the seed in my saved txt and see, that I got 13 words. Is it possible to have 13 words instead 12?

At the beginning of Electrum seed contained 12 words,then from 2.0 to 2.6.4 version it have 13 words,and from next version to today it have 12 words again.But you should not to worry because Electrum seed is compatible with all versions,so your 13 words seed should work in last version of Electrum.

You can also make a backup of all files in Electrum folder before you delete them,just in case you need them.If you have some other PC you can try to install Electrum and use your seed in that way.

But before that try option with blockchian_headers file.

I just deleted both blockchain_headers files and restart it. The synchronizing process took just a few minutes. Nothing changed. Now the wallet is connected, but the last transaction is still +0. 
Yes, I have other PC, but is on Linux. I will try now to download the 3.0.6 for Linux and to restore the same wallet, using the 13 seeds.

[GerGys]

Thank you very, very much! I really appreciate your help!
I downloaded and installed 3.0.6 on different computer (Windows) and restored my wallet, using the seeds. Now everything is fine with the transaction and the amount is in my balance.
Just have some more questions and will be happy if you help me again!
If I copy blockchain_headers file file from the working wallet and paste it to the previous wallet (which is on different computer), will make it work fine? What do you think about it?
Is it fine to have one wallet on 2 computers?

You can try if you want but now that you know you can restore from seed I'd probably prefer to delete Electrum and all the data files and do a fresh installation.

Yes, no problem at all.

I'm glad that you solved the problem, probably issue was about some corrupt file which is caused by upgrade from old version of Electrum.Since you try deleting blockchain_headers file before and that did not solve problem you should not do that.Just make clean install and your wallet will work without problems.

You can have one wallet on many devices,this is not problem-only be sure that they are on clean PC,and that you set strong password.

Thank you very much, friends,
I uninstalled everything from the computer (the one with not working wallet), do the installation again, restore it from the seeds and now everything is working and the last transaction is in my balance. Now have one working wallet on two computers.
Thank you very much to all, who helped me! Hope I also will be able to help to someone here!
You are all great, nice and intelligent people here!
A huge THANK YOU!
