Hey,

i have a big problem and hop that someone can help me.

I read a lot of articls about the keystore file. And I am now frustrated because my PC crashed and I havent made a backup of the keystore files.

I have a lot of coins and I am not belive that all my coins are now lost.

I can see my Etherum account on https://etherscan.io/ but can not access it. I know also the password of the account.

Do i have any possibility to access my coin? To transfer the coins to other addresses?

Otherwise I would lost thousands dollars!! :(

I would also be ready to hand the helper some coins out.

Thanks for any help!

At the end of the day, you are responsible for your wallet. Anything can happen, and has certainly happened with me but luckily I backed up.

If the files for Mist magically disappeared (keystore) you should've had a backup at hand, ESPECIALLY when handling with a large amount of coin. Are you sure the cause of the problem is the wallet, is it not your PC?

Yes of course i am self responsible for it.
Yes it is my PC and it crashed. I hop i can restore the keysore file.
Or do i have an other option if the restore is not working.
Maybe to remake the private key with the adress and the password?

@ethermining123 if your harddisk got corrupted/the OS doesn't start anymore, first step is to not "touch" it, meaning not deleting/writing anything to it.

  • use some linux live-cd to replicate the whole disk (basically create a backup)
  • research and apply recovery utilities on the backup disk

Note that there are also professional services.

Thanks for your answer @luclu
Now an expert tries to restor the files but he douesnt think thats working because the ssd crashed and it is much complicatet to restore files from a ssd as from a normal hard disk :(

But there must a way to remake the private key if i have the address and the password?

Thanks @luclu

But the expret is no so optimistic that he can restore it, because of the ssd :(

Maybe in the future its possible to remake the private key?

Do you have any of these?
-Keystore
-JSON File
-Mnemonic Phrase
-Private Key
-Parity Phrase

If you do have 1 of the above mentioned files/keys/phases, then there will be a possibility to recover your coins. And I'm willing to help you with that, and no I'm not going to ask you to send those files to me (never do that to anybody!), I'm willing to help you by giving step by step instructions over mail/skype/whatsapp anyway you prefer.

Hey Cryptolifestyle,

thank you for your answer!

where can i find this kinds of files?
-JSON File
-Mnemonic Phrase
-Private Key
-Parity Phrase

I think i had just the keystore file because i created my wallets with the mist/wallet one of the first version ('Ethereum-Wallet-win64-0-8-1').
As i know the mist/wallet just created a keystore file in appdata or are there also other files?

Thank you!

Rule nr. 1 You should use your hdd/ssd on which the %APPDATA%/ was stored as little as possible to prevent your system writing new data over the old one.

Could you be more specific about your crashed pc? And what you have done so far?
As I understood it had a SSD, but what kind of crash was it? Did you reinstall a new operating system (like Windows/Linux/Ubuntu etc)? Did you do that with the recovery option of the operating system you ran at the time of the crash? (Windows has an ''recovery'' option which reistalls a new operating system, but keeps the old files (in the folder windows.old or Windows.old.

If you have a file named windows.old in the C:\ directory, then your keystore or .json files could be found here. You can do this manual or using a file searching program, but I do recomend you doing it manual to prevent installing additional programs and getting a higher risk of writing new data over the old one.

Recuva is a recovery program that could recover lost data.
Use Recuva and try looking for the %APPDATA%/ and try finding your keystore file or a .json file, it is mostly stored in C:\Users\USERNAME\AppData\Roaming\Ethereum. Looking in the C:\Users\0007\AppData\Roaming\Mist directory could also be useful for finding your keystore or .json file.
You could also try looking for Ethereum-Wallet-win64-0-8-1 through Recuva, as there is a possibility that you unintentionally made a backup in that folder.
If you found the keystore or .json file then you're ''saved''!
Make a copy of these files on an empty USB drive ASAP! Just in case!
Go to myetherwallet.com and try to recover your funds, or install a Ethereum wallet (on a different pc/laptop! Because you are not safe yet as you are not sure if you can acces your funds! And you should not risking the new installed ethereum wallet to rewrite the files you just found....) and import your keystore or .json files.
I recomend you using myetherwallet.com (watch out for phishing websites! Make sure you are on the official website!) because here you don't have to wait for your wallet to sync to acces your funds.

I really hope this will help you getting back your funds!

I forgot to tell you that Windows 10 has the %APPDATA%/ or AppData folder as a hidden directory.
You can unhide it by:

  1. Go to C:\
  2. At the right top corner you will see the button ''Options'' or ''Folder Options'' or something similar to that. Click on that, you will get a pop-up window.
  3. At the top of the pop-up window you will have 3 tabs. (General, Display, Search). Go to Display.
  4. You will then see a list, go through the list and look for anything that hides files for you. And uncheck/check them to make all the files visible for you.

Watch out to not delete anything crucial as this options gives you acces to system files which should not be touched!

Unhiding files will make it easier for you to find the keystore .json files.

Good luck!

Hey Cryptolifestyle,

thank you so much for your answer.

I double checked now erything. I used recuva checked windows.old folder etc.
But no success. I hop the next time the developer will point more out where they store so important files. I made backup etc. i also have a NAS with Raid 1 where the wallet files are on but not the keystorefile. I know i am self responsible what i do but i made backup from all the other files expect the keystore file becaus i didnt know and nobody told me to save it. Now there are my actually 1/4 million in wallets and nobody can use it. The only way to get on my wallets is to re-generate the keystore file with recover its impossible. I have everything else...installation of the wallet where i created it...the password 2etc. I ckecked it 4 times and 2 expert companies too.

I have nothing from my 'luck'
