Since reformatting your phone, did you continue using the phone? And did you write much data to it?

There is a chance, albeit small that the wallet was not overwritten when you formatted your phone, you might be able to use a data recovery program (e.g Recuva) to retrieve the old wallet file.

For now, stop using the phone as the more you use it, the higher the chance it gets overwritten.

I'd say casually. I don't do something crazy with my phone. Phone calls and surfing on the web when need be & listen to music. That's about it I think.

Thank you for the info! How would I proceed to use Recuva on my phone?

You could just take the SD card out of the phone, and use Recuva on your computer to try and recover the files. This will likely be quicker as recovery processes with a deep scan can take hours depending on the side of the card. Just make sure you demount the card properly to avoid corruption and give the best chance of recovering any files which may be on there.


I succeeded to make it work on my SD card but not on my internal storage. When I choose the internal storage option on Android, the drive doesn't appear on Recuva. Whereas if I choose mass storage (only external) it appears.

I'm trying to recover the SD card first because I'm not entirely sure whether the backup was saved on internal or SD.

Edit: not on the SD card. Checked all the files. Now how do I get it to recognize my internal slot?

You'll need to enable mass storage on the device, this should be available in settings if you're using android. I'm not sure if it's possible on iOS.

Mass storage mode (MSC) is only for the SD card. I've used it to recover deleted files on it. As for the internal card, I have to use debugging mode which I turned it on and use the "transfer files" (MTP) but the phone doesn't show up in Recuva for some reason

Hi, I had created about a year ago a wallet through my smartphone. I had to reset my phone and I didn't back up my wallet at that time. I still have the public address and potentially the private one and I also have the password.

What can I do to restore my wallet?


Do you remember which client you used when you created that wallet?

this one: https://play.google.com/store/apps/details?id=de.schildbach.wallet&hl=en

Sorry about that. It's 32 characters in all. And 34 for my public address

Hmmm... I'm sorry to say, but a 32 character private key starting with a 9 doesn't sound like a commonly used format to me (i can be mistaking tough)... This doesn't mean that it's impossible that this is a private key, but AFAIK it's not a commonly used format, so "standard" wallets like bitcoin core, electrum, the (depreciated) multibit (HD), armory,... will probably not support importing it it.

I guess your best chance will be to try to install the wallet you had on your phone before (the one you used to backup/export/save/... the private key) and see if you can use that private key to restore your wallet on your phone.

I think it's a goner. Nonetheless, thank you for your help. I should have backed it up at the time...

Edit: Well, I just tried it. It's not the private key. Sad Sad Sad

Had 15 bitcoins on it.

Like i said in my previous post: if you tell us the first character of the presumed private key, and the number of characters, we can see if it's a private key in a different form (a private key can be shown in many different ways, and not every form can be imported into every client)

EDIT:
Alternatively, you can download the sourcecode of https://www.bitaddress.org and run it on an offline machine, then try your private key in the "wallet details"-tab. This tool does not support all formats, for example the Mini private key format isn't supported (AFAIK)


9--snip-- is the beginning for what I thought was the private private key

My public address and the password, those I am certain of but they won't be of any help apparently

Please, edit your post and remove everything but the first letter (you really, really, really don't want a big part of your private key floating around online), and please add the number of characters of your supposed private key, it'll help us to make an educated guess as to which information you might hold


Sorry about that. It's 32 characters in all. And 34 for my public address

Edit: 32 characters, sorry I can't reply fast enough cause my new account is restricted to a number of posts per minute.

Download Bitcoin core and use the command to import a private key and try what you think is the private key. If it works you should have a new address in the wallet which you should see your funds in.

I downloaded the client but I don't see any option to import a private key, any particular place I should look in?
