Hi again,

@HCP

To test with different derivation paths did not solve my issues.

All 4 transactions are to different addresses.

When I look at it I see that I might have given you wrong information earlier, from what I can see on oxt.me it looks like this:

1. Trying to recover bitcoin balance on mycelium iPhone, showing balance 0 etc
2. Trying to recover bitcoin balance to  android mycelium, showing correct amount BTC
Ps. Both iPhone and android were restored using the same seed.
3. Sending all balance to the iPhone mycelium wallet, since the android phone wasn't mine. (In theory sending to and from myself, same seed)
4. A few days later selling 1 BTC at Kraken. First small transaction, then 0,99 BTC.

5. Then a year later wanting to check, finding mycelium on iPhone is not installed. Installing app, recovering with seed, finding the balance is 0,000X and not the correct. Also testing with android, but also showing 0,000X BTC.
Ps. We do not know what happened to the mycelium app on the iPhone, maybe we deleted it, but at least thinking it was the same seed, since we recovered with seed and sent between two wallets with same seed.

@nc50lc

The amount on our wallet is the same as the change address on the transaction 4.
For me looking it looks like it leads to a new transaction, from where the BTC is laying unspent.

What I make out of this is that we only see 4 transactions, all from transferring BTC from android to iPhone (same seed - no passphrase)

We are missing the transactions from a few days after, selling the BTC on kraken from the mycelium iPhone. This was also done in two transactions.
One to verify and one to sell when seeing it is working.

---

The question is why these transactions do not show up (not even on the iPhone), and that there might have been a glitch between the mycelium android and iPhone versions causing the two wallets to be different even with same seed? (One for the android and one for the iPhone).

And that is why the wallet showed 0 BTC, and that when we sent the BTC to "ourselves" iPhone version created a different set of addresses and did not manage to attach it to our wallet seed used in the android?

Ps. The phrase we had on the same paper is not our passphrase as we are 99,99999999999999999999% sure we never used a seed and only used the same seed on both phones, we do not have knowledge about this so we did check it throughly before doing the transactions. (Not throughly enough though it seems like).

Any ideas on where to go from here?

@BitMaxz

I am not sure I understand what you mean. But the balance is the same on the iPhone and the Android now when restoring.

When I am at the balance side (iPhone) I cannot see any address, I entered the public key, main account, (hope this is what you mean) into blockchain and the balance and transactions looks the same.

"there are 3 types of address on balance" On the balance tab, I only have Main account balance, send, receive and cold storage (iPhone). But that might be different on the Android, at the time of writing this I can not verify that. Probably I need the Mycelium app for android to check all three account types?

With regards to looking into the Electrum wallet it says:
Script type: p2pkh
Wallet type: standard
Seed available: False
Keystore type: bip32
Lightning: Not available for this wallet
Derivation path: m/44'/0'/0'

This makes me wonder, since I seem to remember that to restore my mycelium wallet the guide said to check bip39, could this mean something?

@HCP

Sorry for the stupid question, but are you referring to if the "output" addresses are the same in #3 and #4?

I tried adding new accounts (iPhone) with no success.
But did not get a question to ensure it was HD accounts.
I do not have the possibility to check the android at the time of writing this. Would you know how I could check this in electrum?

@nc50lc
Sorry for the confusion. Thanks for the assistance.
I think you are correct on the balance that it is the change of transaction #4.

I do not think it was backed up after the transfer, therefore no new seed. With "keep on restoring it with your commonly used passphrase." you mean that I should try to guess the passphrase?
(Most likely I do not have any). The reason why I am so sure about this is that I have the seed written down with one additional code, not for this. I had these with me when performing the transactions, so if any new seed and or passphrase they would most likely have been noted down on the same place.

Thanks :-)

Hi,

Thanks a lot for following up and assisting.

I have four outbound transactions in when restoring the wallet.

As I remember them:

All outgoing from Android Mycelium wallet:

1. Small to check that transfer from android to Kraken is working.
2. Sending 1 BTC from android to kraken.
3. Sending small portion from android to iPhone to see I it works.
4. Sending the rest of the balance from android to the iPhone.

5. Deleting mycelium on iPhone
6. Restoring and balance is same as Android Mycelium, 0.000X.

I am trying to look into oxy.me to fully understand the transactions, but since I am before beginner, it takes some time.

All ideas, assistance,  "dummy" guides for transaction explanations and oxt.me guides are heartly welcome :-)

Thanks again for all the answers,

@hosseinimr93
I am 99,999999% sure no passphrase was added. That makes it a bit weird. And leads me to thinking sending coins from yourself (android) to yourself (iPhone) leads to the seed not being updated on the changes on the iPhone after and the coins being sent to another address.

@BitMaxz
We deleted the Mycelium app from the iPhone after the transfer. (At least that is what we think happened)
The iPhone is now showing 0.000X and not the complete balance on the iPhone, so if we backup now this is the balance we backup (0,000XBTC) and not the balance with the total amount of BTC?

Looking at the Android vs the iPhone both balances are identical, also both showing the same transactions.

@khaled0111
The phone was my wife's, so not to worried :-)
We have tried to restore in Electrum, showing same balance as on the iPhone and Android, 0.000X and not the complete amount of BTC.

@nc50lc
That is correct, but also before transferring to the iPhone we sent one BTC to Kraken to sell it, sold this one.
And the rest should be on the balance, but as mentioned it now says 0.000X instead of correct amount.

ADDITIONAL INFO:

iPhone vs Android

Now both Android and iPhone shows same transactions;
Looking at Android and iPhone
   1. Balance 0.000X
   2. Transactions identical

What I find on the Android mycelium app that I do not find on the iPhone mycelium app is this:

Android says:
Bitcoin HD 1
Account 1
Contains 9 private keys
Balance 0.000X BTC

Could these private keys be hiding the coins or would the balance then be correct?

Once again, thanks for assisting.

Hi again,

I think there is a chance they are lost, we did not take a backup of the wallet on the iPhone after transferring balance from the android.
We thought they still would be attached to the seed. And that we could recover them from the seed.

It also could be a glitch in the Mycelium wallet if they were supposed to be recoverable from the seed.

Is there a way for me to trace the transactions and prove they are mine?

Thanks.

Hi again,

The thing is that when I restored the seed on the iPhone I could not see the correct balance.

I could only see the correct balance on the android.
I then sent the coins to the iPhone. (Which was restored with the same seed, but not showing the coins)
Then sold one.
Then deleted app.

I am not an expert on transactions but I have been digging into a bit today, and that's why I suddenly came to think about the change addresses.

In the transaction history all transactions are done the same day as when we sold the one.

The remaining looks to be on a change address (As mentioned I am not expert and this could be wrong).

But maybe then they are on a change address created by the iPhone mycelium and not the android from which we sent them...

Should I have backed up the iPhone wallet after selling one coin? Since the remaining was sent to the change address?

My question now is if this is correct and I find the change address, can I regain access to it? and how?

Thanks again, priceless help, it is much appreciated.

Thank you @Charles-Tim,

I restored the seed on both the android and the iPhone. But the coins only showed up on the android.
Same seed was restored, but the iPhone did not display the coins.

Since the android phone wasn't mine I sent them to the iPhone.

Then the coins appeared on the iPhone, I then sold one coin. It displayed six...
Later probably deleted the wallet from the iPhone.

When I tried to restore about a year later the balance is the same, both when trying to restore on the android and the iPhone, BTC lost, hopefully temporary.

Where would you suggest to try from here to recover the coins?

I have the original seed.

Thanks a lot for your answers.

INFORMATION UPDATE.

Thanks for trying to assist me in this matter. I realised one vital thing that I forgot to include in my information.

When I had sent the money from the android phone to the iOS phone I sent one coin to kraken to sell it.

Could this have caused Mycelium to generate a change address on the iphone? And that the remaining BTCs are in this change address?

I am 99.99999% sure that the same seed was used on both wallets when we sent the BTC from android to the iOS, if that is the case is there a way to get back the money from this change address?

If we did not use the same seed, is there then a way to retrieve the money if we locate the change address?

Thanks for helping me trying to sort out this issue, highly appreciated.

Thanks @nc50lc for your message and assistance.

Passphrase solution
At the point of writing this I have to assume I can not trust myself and will try all proposed solutions. Will it affect my wallet if I try to restore "another" wallet with a passphrase?

Lets say I:
1. Delete my wallet
2. Try to restore wallet as proposed with same seed + passphrase
3. Will I then after be able to restore my wallet only using the seeds? (no passphrase) after?

Regarding sending to same wallet, will the keys be different types in iOS / Android and make me have to search for other keys/account types?

Sadly not the wrong BTC mBTC :-)

Thanks a lot for assisting!

Thank a lot all of you for answering and trying to help, this is highly appreciated.

@dkbit98
I used the same seed on different devices since I could not restore it on my iPhone, balance showed 0 BTC, I was afraid they were lost.
Tried then the Android where I managed to restore the coins.
Then transferred the coins to my iPhone. Same seed was used on both.

I tried with importing the seed to Electrum, no luck.
When using blockchair are you recommending me to search my wallet public key? Or the transaction IDs?

@Charles-Tim
"BlueWallet, it will be a good wallet most especially for beginners that want to make use of lightning network". What do you mean by this sentence about BlueWallet? Is it good for trying to recover? Sorry, I am at the stage before beginner :-)

@NeuroticFish
I tried several times to recover the wallet on the iOS before going to the android.

I am not sure if I understand how to check the addresses, but:
- When looking at the transactions overview, red transactions, outgoing they all start with 1.

- When I enter the transaction I have a transaction ID but also inputs and output addresses, which are you referring to?

Transaction 1:
In transaction overview address showing starts with: 1
Transaction details:
Transaction ID starts with c
Inputs start with: 1
Output 1 starts with: 1
Output 2 starts with: 1

Transaction 2:
In transaction overview address showing starts with: 1
Transaction details:
Transaction ID starts with 2
Inputs start with: 1
Output 1 starts with: 1
Output 2 starts with: 1

Transaction 3:
In transaction overview address showing starts with: 1
Transaction details:
Transaction ID starts with b1
Inputs start with: 1
Output 1 starts with: 1
Output 2 starts with: 1

Transaction 4:
In transaction overview address showing starts with: 1
Transaction details:
Transaction ID starts with 2
Input 1 starts with: 1
Input 2 starts with: 1
Input 3 starts with: 1
Input 4 starts with: 1
Output 1 starts with: 1
Output 2 starts with: 1

The seed should be the same for both wallets, could it be that they are showing as different account types / address types in the iOS and that I have to restore them another way?



@hosseinimr93
"Are you sure that both wallets had the same seed?" Yes I am sure they had the same seed.

"The other possibility is that your IOS wallet wasn't synced at the first, got synced after a while and the balance was shown." What would happen in this case?



@BitMaxz
Sadly I did not find them in Electrum. Which address do you suggest I use to look in the block explorer? The wallet address or one of the transactions?
And if it is the wallet address is this the same as the wallet public key?


Thanks a lot for helping out guys, this is really highly appreciated.

Restored Mycelium wallet on my new iPhone, Seed X, balance showing 0 BTC.
Also recovered the same Mycelium wallet on my wife’s android, Seed X (Same seed) , balance showing correct amount of BTC.

Status at this point:

Wallet (Seed X) recovered to two different phones, one android and one iOS.
Android showing correct amount of BTC. iOS showing 0 BTC.

Action taken:
Transferred the BTC from the android to the iOS.
From my wife's telephone to mine.

Status at this point:
iOS mycelium wallet showing correct amount of BTC.

Actions taken later:
iOS mycelium app deleted. (99% certain this is what happened)
Then tried to reinstall mycelium wallet on iOS with the same seed.
Balance showing 0.000X BTC.
All transactions visible in the transaction window.

Also tried to go back to the Android phone and recover again with same seed, but also the wallet when restored on android is showing 0.000X BTC.

The big question:
Where is my BTC and how can I recover them?
