Didn't manage to crack it but anyway thank you guys for all your help, Much appreciated!!

are you able to share the wallet file or hash in private (after of course all funds are moved out etc) ?
it would be interesting to see if this is some hashcat bug/problem or not
of course we would need both the file/hash and also the password

I think by looking at this source code files:
1. https://github.com/blockchain/My-Wallet-V3/blob/c0bf5615c862fb8d7ec5e3f5031c2998b8ddc690/tests/__data__/wallet-data.json#L8-L22
2. https://github.com/blockchain/My-Wallet-V3/blob/c0bf5615c862fb8d7ec5e3f5031c2998b8ddc690/tests/__data__/signing-data.json#L3-L38
3. https://github.com/blockchain/My-Wallet-V3/blob/c0bf5615c862fb8d7ec5e3f5031c2998b8ddc690/tests/blockchain-wallet.spec.js#L18-L52
4. https://github.com/blockchain/My-Wallet-V3/blob/c0bf5615c862fb8d7ec5e3f5031c2998b8ddc690/src/blockchain-wallet.js#L447-L463
we are missing some patterns for sure, maybe this is a complete list:
guid
sharedKey
double_encryption
dpasswordhash
metadataHDNode
options
address_book
tx_notes
tx_names
keys
hd_wallets
paidTo
compare this with what we currently support in
https://github.com/hashcat/hashcat/blob/a4b39b7b9c8e3d9297261bd4cee1d2bb4324680e/OpenCL/m12700-pure.cl#L348-L423
the loop in the hashcat kernel is used because there could be tabs, spaces and parenthesis before those strings (see also the discussion over https://github.com/hashcat/hashcat/issues/1937#issuecomment-469038973)
So if we really are expecting/know that some of these patterns are missing, we should add them for sure. What do you think ?

@jennifer4682 We did some changes on the code: https://github.com/hashcat/hashcat/pull/2249
we would really need that you tests it to make sure that this fixed your problems (you can use the beta https://hashcat.net/beta/ which includes the fixes).
Could you kindly test it and report back. Thx
