Hi eagleman and BitMaxz,
first at all thanks a lot for spending time to understand the issue, I'm really pleased to receive your answer.
I'm not happy to inform you that the electrum is still not working and, as I read, I'm not the only one experiencing this issue I have never seen before, after months of usage without any issue.
PS 1:
As I posted this topic two times (here and in the generic electrum thread) I will go on here to explain the problem details.
(previous posts with another user experiencing the same issue can be found here:
https://bitcointalksearch.org/topic/electrum-received-transaction-with-0btc-instead-of-0275-2829027)
PS 2:
I'm a senior php developer and not a crypto beginner, so please trust what follows and I'm happy to have found a way to "bring" electrum to show an error in windows so you can also experience it and debug.
Before going on:
1) The wallet is standard (no segwit) and btc address used is correct
2) I restored the wallet (originally in android) also in windows and problem still persists
3) Tried to restore 3.0.5 and also previous version 3.0.4: same error
4) Tried to change any server available (auto connect off on android and windows). Wallet stays in "syncronising" status for a lot and anything else happens
ANY OTHER TEST (I did several) FAILS, BUT I FOUND A WAY TO SHOW THE CRASH OF ELECTRUM ON THE BLOCKCHAIN IMPORT
I used this electrum wallet (installed to a non-expert friend under my suggestion) just to receive two payments through bitpanda.
PAYMENT 1) Jan 21, 2018 7:26:52 PM
https://www.smartbit.com.au/tx/c8a962695ee04ad479064b894170350d7140f36149470dc5374ea097ee36f8c8WALLET: 1LGMbP8kCeWJ8oQeVaoRfYRguFsrExaVnR (first address in the list of addresses of the wallet)
AMOUNT: 0.17004005 BTC
Status: payment received, balance updated.
PAYMENT 2) Jan 26, 2018 7:18:52 PM
https://www.smartbit.com.au/tx/b18a38be693a5dca1aae2326351cb80c3ca64616559f0c4c5c9b6d2d8841d9cbWALLET: 1LocrF7CRP9m9RcddKrVr94GfLUR66VVuM (third address in the list of addresses of the wallet)
AMOUNT: 0.27569181 BTC
Status: payment RECEIVED BUT 0 BTC AMOUNT, balance NOT UPDATED, electrum still in "syncronizing"
HOW TO SEE THE ERROR IN ELECTRUM (WINDOWS)
Tools -> Load transaction -> from the blockchain
1) FIRST TX c8a962695ee04ad479064b894170350d7140f36149470dc5374ea097ee36f8c8 WORKS AND SHOWS DETAILS
2) SECOND TX b18a38be693a5dca1aae2326351cb80c3ca64616559f0c4c5c9b6d2d8841d9cb ELECTRUM CLOSES WITH ERROR WINDOWS
I seriously hope it will be possible to understand the matter, because as you tell, the BTC amount is associated to the right wallet address but my friend cannot use his 2500€ in BTC (not little money!).
As I suggested him to invest in BTC, trust cryptos and use electrum as the safest software wallet... I really feel in fault for this situation... it was the second time he was changing EUR to BTC!!
So I hope there will be a solution for it.
I also hope to have provided enough information to test the source code until the problem is found and solved.
In any case the problem looks like to be something new, as you can see 5 days ago I did exactly the same procedures from the same exchange and everything worked perfect.
The only difference is that on the second tx I used the third address in the list instead of the default (first) address.
Can be bitpanda (or somebody else in between) changed a procedure from standard to segwit and this doesn't work on standard wallets anymore?
Let me know if you need screenshots or everything else can be helpful.
Best regards
Fabio
