Are there any tech folks from blockchain.com here? Honestly, I'm not sure if their support team really gets my issue...
Back in 2014, when blockchain.com still went by blockchain.info, you could upload your wallet.dat from bitcoin-qt to bring in your addresses and keys into the wallet.aes.json. I used this feature and imported my stuff there. But then I ended up removing the keys, keeping only the addresses for viewing.
Time passed, and I accidentally deleted my original wallet.dat (way too long ago to recover it now). So, my question for blockchain.com is: do they still have copies of uploaded wallet.dat files on their server? Can I get mine back from there?
By the way, the wallet.dat file was uploaded to their server instead of being decrypted locally, which you can see in the "uploadWallet" function link.
Blockchain.com or .info are online wallets we do not know what they do to the wallet files you uploaded to their site even if they have your wallet.dat or not I don't think they will let you have it.
If you accidentally deleted the wallet.dat have you tried to use some recovery tool like Pywallet? It can recover deleted wallet.dat.
Or alternatively, if you still have the wallet.aes.json file use the link below to recover your wallet.

Thats why I asked at the beginning of the topic if there were blockchain representatives here.
It was deleted a long time ago and has already been overwritten with new data.
I have this wallet.aes.json, but it only contains addresses, without private keys.
No luck if it only contains addresses and how did you know that it had already been overwritten?
Why not try your chance to recover it using the Pywallet? You don't have any other choice but to try it.
Only if you still interested you can follow this guide https://bitcointalk.org/index.php?topic=38004.0
The encrypted payload from wallet.aes.json contains only addresses and other useless information.
There is only one private key, and not from wallet.dat
The data on the hdd is overwritten, part of the ckeys from the berkeley db is missing.
If I hadn't tried anything, I wouldn't be writing this.
No one from blockchain will ever write to you here, they only go through the original blockchain.com webpage.
You can ask for support here: https://support.blockchain.com/hc/en-us
Knowing a bit how blockchain.info used to work, it all depends if you migrated to a new wallet ID or kept the same.
Also, did you ever keep the original wallet.aes.json file?
When you remove addresses/keys from the wallet, they sometime create a new wallet ID, and the new ID has only the requested data. So if you ever saved an old wallet.aes.json file or kept the original wallet ID you might be in luck.
The way the server works if you didnt login for a lets say blockchain.info v1 account since 2014, they still have that original wallet, but if you logged in and did transactions, its upgraded to v4 (March 2024) and has a totally different encryption and format.
If there is anything else try the support link above.
Good luck!

Yes, I have this original wallet.aes.json, but it contains data in this format (decrypted data, keys section):
that is, addresses 2 to 5 without private keys (decrypted using btcrecover).
BC support eventually answered me by email that they do not store files on the server (the expected answer).
I have about twenty of these wallets and in one of them is 14 bitcoins. I have no idea which and I have no idea if I can guess the passwords either. What I think happened is that I was arrested and then forgotten about these 14 bitcoins since I had already written it off back then - and ended up taking a 10 year prison sentence not long after and the police surely couldnt have decrypted my phone back then since at my trial they had not entered anything digital against me even though they had seized around 7 or 8 phones across a span of time.
So how to fucking restore these, I have the wallet identifiers but not the original data or anything else.
This looks like a wallet you can import to electrum, it will show balances but you wont be able to move unless you have a password
Hashcat has now some new interesting electrum modes in version 6+
