On a non-technical note here, please be very cautious before handing over your phone to some unknown tech guy: he could easily fool you saying he was not able to recover anything and then he recovers the coins for himself. Just be very cautious on this: demand you can be present when he operates. Good luck with that anyway

p.s. also, if the recovery is successful you might gain access to fork (shit)coins too.  Wink

Also, be warned that in a lot of instances, "rooting" the phone will require an unlocked bootloader... if the bootloader is not already unlocked, doing so will often completely wipe the device as a security measure.

From memory, some of the US versions of the S4 were locked... but the "international" versions were generally unlocked and relatively "easy" to root.

If you are willing to try to recover the wallet file you can able to access the file with this path or folder location.

- /data/data/com.mycelium.wallet/databases/wallet.db

But you can only able to access it if your phone is rooted.

If you don't know how to root your phone post it here and let us find a way how to root your phone.
Tell me the complete details of your phone.

Take note: If you root the phone you are vulnerable to any attacks, malware, and virus. So make sure to don't connect it to the internet while looking for the wallet.db or something related.

However, based on your replies, it seems like there is a chance that if I root the phone as you suggest I can get access to those keys.

If the files weren't deleted, yes.
If they were deleted, only a file recovery could yield some results. But this is rather unlikely to be successful (might be still worth a try tho).

Android stores program data on the removable SD card so one thing you can try is take that out of the phone, insert it into an SD card reader, insert it inside a computer and running file recovery software on that drive.

@OP:
Don't you have any form of backup? Your mnemonic code?
Did you "just" uninstall myeclium or did you actively delete all mycelium data / wipe your smart phone? Uninstalling the application doesn't necessarily mean the wallet files get deleted. Might be worth to try this out on a second mobile.
Rooting your mobile without wiping the storage would be your best bet. Then you'd be able to access the wallet file and all private key.

It was a very fast install, transfer of funds, and uninstall. I don’t have a form of backup or the mnemonic code. The phone was never restored/wiped since. I do remember trying to re-install mycelium but remember that not restoring the original wallet. There have been some anecdotes of people trying this and it working. However, based on your replies, it seems like there is a chance that if I root the phone as you suggest I can get access to those keys.

No, definitely not.

Android makes use of the unix permissions as a security measurement.
The SD card is "free for all". Any application can read/write to it. That would be the last place the wallet file should be stored (and it isn't).

It is stored where it belongs to. In the data directory of the mycelium application owned by the mycelium application user.

I doubt so, I've used MyCelium in the past and if memory serves me right, I had to root the phone to access the secure storage and extract the keys. I forgot if I had it encrypted or not. Storing it in an SD card would be pretty insecure. That is, unless the wallet had a backup for which it'll be in PDF.

IIRC, S4 was generally fairly easy to root and wasn't as complicated as the S-Off in my old HTC. Since you've uninstalled Mycelium, I suspect the files wouldn've been overwritten already. No harm getting it to a specialist to try to get it recovered, the process could be slightly complicated but might be worth the try especially if you're sure it contains a certain amount of Bitcoins.

Do research on Android file recovery programs/apps. Unfortunately I haven't tried any so I can't really make any recommendations. Probably try this route first before spending money in hiring people. And while I'm definitely not guaranteeing any results, you pretty much have nothing to lose anyway and it wouldn't hurt trying.

Lesson learned: backup your recovery phrases people.

If you already uninstalled the mycelium all data will be also removed including the wallet you created from the mycelium app. That's why mycelium always gives notice or warning that you need to back up the seed before you use them if not then there's no way to recover the wallet after you remove the whole mycelium app.

Try to check your notes maybe you have a backup seed phrase it's a 12 words phrase that you can use for restoring your old wallet. If you can't find it there then you can't be able to recover your wallet.

Samsung Galaxy S4 can take up to a 64GB-sized SD card, so the chances of your wallet file being overwritten is very low, even if you have a smaller size like a 16GB SD card, considering you practically never used the phone after you removed Mycelium.

Mycelium is pretty annoying in trying to make you backup your wallet, which iirc means your mnemonic seed.
I'd start with trying to remember if I've done such a backup and where I've saved it.

It could save you from a lot of effort in directions that may get you nowhere.

Good afternoon,

I have an old Samsung Galaxy S4 that once had a mycelium wallet with some funds. Mycelium was installed, and then uninstalled form the phone in 2015 with the funds still in the account, and after some surface level recovery attempts I gave up on trying to get them back. The phone was not used very much within the past five years (maybe a total of two months as it was a backup), hasn't been restored, and hasn't had any storage issues for potential defragmenting issues. Fast forward five years and I am considering sending the phone to a specialist to try to find and extract the wallet.db file. Would something like this be possible or am I wasting my time?

Thank you,

Johnmark
