Trezor Troubleshooting Guide

I've noticed some redundancy in some of the issues raised on this subreddit, thought I'd start a generic troubleshooting thread of what I've found useful. I'd appreciate any suggestions mods or other experts might have.

I - Prerequisite

  1. Read the FAQ
  2. Read the Users manual
  3. Read the Developers guide
  4. Search the Wiki
  5. Try the trezor Troubleshooter

II - Trezor connectivity / stuck spinning circle

  1. Try different cable / USB port / computer
  2. Try without crappy Antivirus software.
  3. Manually add the bootloader registry value just to be paranoid.
  4. Install WinUSB driver with Zadig.
  5. Try disabling browser extensions / ad-blockers.
  6. Try Chrome Guest Mode (easiest way to disable extensions)
  7. Try different browser (Chrome / Chromium / Firefox / Brave)
  8. Try WebUSB
  9. Try Android
  10. Try VirtualBox
  11. Try old-wallet.trezor.io
  12. Try beta-wallet.trezor.io
  13. Try beta-wallet.trezor.io/next

III - Updated FW, coins are gone

  1. Try Legacy Account section.
  2. Did you use the right seed?
  3. Did you use the right passphrase?
  4. Did you enter the recover seed words in the order the Trezor asked you to (hint: not first to last)?
  5. Did you verify that your recovery seed words are in the word list?
  6. Did you check all accounts (click add account) for transactions, or check all MEW ETH accounts (next page) as well?
  7. Did you check your transaction history (Legacy and Segwit) to see if anyone moved coins while you were dormant?
  8. Did you regularly do a dry-run recover to verify that you actually possess the recovery seed that the Trezor is operating with?
  9. Check to see if your brother-in-law found your seed and stole your coins.
  10. Check to see if the digital copy of your seed was hacked.

IV - Can't / Don't want to update FW.

  1. Try performing a dry-run to ensure you have the right seed.
  2. Say a prayer and hope you have the right passphrase.
  3. Use an old version of Electrum / MyCrypto / MEW to see if you can find TXN history.
  4. Use an old version of Electrum / MyCrypto / MEW to move most funds.
  5. Use an old version of trezorctl to move the other funds.
  6. Buy a second Trezor and update that.

V - I'm new to this, How should I backup my seed / passphrase.

  1. Make it simple, your kids / kin may be the ones doing the recovery.
  2. Make it secure in a lockbox or safe or something reasonable.
  3. Make it accessible in case there is market volatility.
  4. Make it resilient and redundant in case there is a fire / zombie apocalypse.
  5. Don't make it digital, hackers are smarter than you are.

VI - I forgot my PIN now I can't access my device

  1. Say a prayer and hope you have the right seed.
  2. Say a prayer and hope you have the right passphrase.
  3. Wipe your device then recover with the seed / passphrase to reset PIN.
  4. Don't forget again.

VII - I forgot my seed / passphrase, what now

  1. Nothing, you effectively put physical currency in an incinerator, no getting it back.
  2. Realize that you've learned a valuable lesson that will serve you well in the future.
  3. Advocate to others the importance of following section [V] above.

VIII - I want support for CrappyForkCoin and I want it now!

  1. Figure out what the fork_id is for CrappyForkCoin and write your own coin JSON file.
  2. Use your JSON file to compile your own CrappyForkCoin trezor FW.
  3. Flash your CrappyForkCoin trezor FW to your personal trezor.
  4. Use trezorctl to make CrappyForkCoin transactions.
  5. Read the wiki on how to add coins just to make sure.

Bitcoin and Ethereum gone after updating Trezor

So I have not used or checked my balance on my Trezor One in a good 7 months. I finally decided I should update it. I forgot my pin but I have all my seed words written down and stored in my safe. I did not have a passphrase. I successfully reset the Trezor and followed to input the seed words in the order they provided. Some were random works asked by the Trezor and some said to enter word 6 or enter word 1 etc. I followed this exactly. When I look at my wallet it shows 0 bitcoin. The legacy wallet shows 0 bitcoin. When I go to MyEtherWallet it shows 0 ETH. I'm freaking out. I have reset the Trezor multiple times thinking I might have entered a word wrong and the same thing happens. Can someone please help me. I would really appreciate it.

Blockchain.info | two factor authentication reset request

Hi, so this is my story: I was using Bitcoins a like two years ago, stopped working with them. A few days ago I wanted to take a look whats going on and found out bitcoins are rising again. I took a look into my bitcoin address and I still had like 2 BTC which I forgot about. So I tryed to login into my blockchain wallet (I still have most information written down) but it wants me to do an authentification, for that they send me an email. The problem is I don't have access to that email account (restoring is not an option as the E-Mail provider bascially shut down their service). So I found out I could use this https://blockchain.info/wallet/reset-two-factor form to have them put a new email address into my account. The thing is I have read that blockchain isn't really doing any support and not working through those forms. So I wanted to ask is there anyother way for me to get access to my blockchain wallet? I still have my wallet identifier, password and the passphrase (if it is the 17 words long thing)
TL;DR: Lost acces to my email account but blockchain wants me to authenticate myself using said email. Which reliable ways are there for me to restore access, using this form (https://blockchain.info/wallet/reset-two-factor) isn't really reliable as I heard. I have the passphrase.
