QA

What to test

1. FW upgrade for all our devices - happy path
2. FW upgrade failed
   • update rejected on device button request
   • cable disconnected during all different steps of FW upgrade
   • shitty USB cable (if possible)
   • when nothing happens for more than minute it should show button What if it gets stuck? (pressing buttons does nothing for now) and it should dissapear when something happens (progress or user accepts button request on device)
   • Retry button should work in all of these error cases
3. Test devices with PIN and also without PIN set
4. Test that remembered devices stays remembered and not remember stays not
5. Test that discovery doesn't run again for not remembered devices
6. BTC only FW should work too and stay BTC only and same for Universal FW
7. FW translations should work too
8. When system ask for permission after update, try to wait for few minutes before accepting it. It broke it for me once but I was not able to reproduce it then.
9. Everything should be nicely animated and smooth - I put lot of work into this so don't hesitate to be nit-picky if something doesn't feel right
10. It's not possible to start FW update during discovery
11. After installation end user is redirected to origin screen (Home in case of update banner or to device settings)
12. Changelog modal works correctly
13. You should have seed ready bottom sheet is displayed before update flow begins
14. It's not possible to start update flow for unconnected watch-only devices
15. Remote feature flag works correctly for disabling FW update (not sure how to test it on develop)
16. It's possible to install FW when I have different device remembered (for example I have TS3 remembered and I am going to install FW on TS3 that is not remembered)

Don't know if it's my slow tablet's issue, but this loading circle takes cca. 10 seconds before it changes to blue Update button.
Edit: it's because of coin discovery.

QA OK
Update T3B1 and T2B1 to latest OK ✅
Update T3T1 to latest OK ✅
Reinstall of FW works on all devices as well ✅
Installation of BTC only fw works too ✅

• tested both with PIN and without PIN

• what if it gets stuck modal LGTM and appears after a while when nothing is happening

• I tried to disrupt the FW update multiple ways and multiple times and seems to work nicely, when I connect the device back, I can easily continue with the update (works very nice imo 🎉 ) or I can just "quit" it and continue to dashboard or whatever I want

• view only devices stayed view only and vice versa

• correctly differentiates Universal FW and BTC only fw

• BTC only fws update works as well

• animations feels nice and smooth, haven't seen any stuttering or anything 🙏

• I wasn't able to replicate 8.

• update not possible while discovery is going (as @evgenysl mentioned as well)

• bottom sheet about seed displayed every time

• view only wallets are not possible to update

• tested also: TS3 and TT in view only (not connected) and update of TS5 (that was not in view only) and update went well

• works well also with biometrics (locked my phone after the fw update>unlocked>was asked for biometrics>FW finished fine)

• could not yet test the remote ff disable

• changelog is not present
