Jade crashes when attempting to select 24 words BIP85 with index # > 1230

[totallynarwhal]

On firmware 1.0.30, when I attempt to use a 24 words BIP85 index # greater than 1230, it crashes the Jade device resulting in a reboot.

Repro steps:

1. Select manual BIP39 Passphrase with Frequence Once
2. QR Pin Unlock with Blockstream's blind oracle, i.e. blkstrm.com/pn
3. Enter Passphrase to start session
4. Go to Wallet->BIP85 and choose 24 Words option
5. Use jog-wheel to increment index # towards 2000

[Expected]
I'm able to navigate and select a BIP85 index that's fairly large, i.e. 2000

[Actual]
When I navigate to ~1230, if I continue to press and hold the jog-wheel, I'll start to get garbled text in the ones and then attempting to increment the index further would then crash and reboot the device.

Note: This seems to only be an issue when holding down the jog-wheel, it appears that I was still able to slowly increment the index if I push the jog-wheel right but not hold. But this means I don't have the ability to fast increment! I'm still pretty far away from index 2000 :(

On a related note - having to use the jog-wheel to manually incremental the index # via the carousel UX is also pretty tedious for large index #... it'll be great if we have a UX similar to entering the unlock pin.

Yes, not sure what's going on there - maybe the wheel is generating events faster than they are being consumed and so eventually we run out of [some sort of] RAM or similar. I'll try to reproduce.

Definitely agree a better way to enter large index #'s is needed.

Will investigate using the 'pin-entry' type screens... ie. where you set each digit in turn

Will switch to above for next fw release 1.0.32

Updated to allow index up to 999999 as well - awesome!

Should be resolved in fw 1.0.32
