Ledger device turns off making it impossible to sign certain transactions

[314159265359879]

See here leather-io/extension#5857

Ledger Nano S+ firmware 1.1.2 and stacks app 0.24.2 (I checked with two devices same model).

Reproduction steps
Connect Ledger to Leather (Stacks)
Click swap in the wallet
Choose a token pair and any amount
Click review and swap
Click Swap
See error: in leather shows loading animation with "Waiting for your approval"
Ledger device turns off, or screen goes blank which makes it look turned off.

[314159265359879]

Retested with Xverse, the issue is the same there, screen turns off.
used app.bitflow.finance/trade to initiate a transaction to sign on the device.

Received a user report that attempting this multiple times caused their Ledger to reset completely, with them needing to re-enter their seed phrase. It happened multiple times after multiple attempts.

Withdraw LP on Alex have the same issue and Alex LP tokens can't send to another wallet, so my fund have been stuck because of this bug.

Thanks for sharing, I am checking with the Zondax team for an update on this issue and its resolution. We are aware this is a serious blocker.

This is not an issue with 0.23.3 of the Stacks app, perhaps Zondax has a step by step guide on how to revert to an older version of the app to allow transactions in case of a dire need.

Is the sideload the app only work on Ledger Nano S and Nano S plus ?
I only have Nano X.

Hi again, sideloading doesn't work on the Nano X, because that device doesn't allow sideloading by design. In addition, I tested side loading 0.23.3 and that wasn't supported via hub.zondax.ch/stacks when I tried a couple days ago (with nano S+), I have asked someone from Zondax to see what is causing the issue, I have not yet heard back. I will share here when I do have a viable workaround.

You should be able now to install through Ledger Live the previous version on your NanoX while this issue is being investigated

Hey guys, I'm not a developer but an web3 user and ether.fi moderator :)
I'm here to share my experience in the previous 3 days, where I've tried to use Bitflow's pool (stx-ststx) and at the moment of signing the transaction, my Ledger Nano X would bug, do not show the approval part and reset completely to fabric conditions (3 times) in the same scenario. Once, when trying to figure if the problem was in Ledger/Stacks app or Leather/Xverse, I've taken the device out and he went to booting mode for 3 full days on the plug.
Anyways, I see people are aware of the bug and hope to be fixed soon. Thanks!

[ainhoa-a]

Hi @rzucher we have rolled back to previous version while we keep investigating this issue. You should be able to instal 23.3 again from Ledger Live. Sorry for the inconveniences.

[neithanmo]

Hi @rzucher @314159265359879
I am investigating this issue, so it happens after transaction is reviewed and upon approval(where the transaction signing comes in) it crashes?

[rzucher]

Hello Natanael, actually my problem went a little bit further my device actually reseted to fabric conditions three times. it would bug when the transaction should be appearing, and then it would turn off and back to fabric. Once it even went to a booting screen where it took 3 days on the plug to come back working normally *Rodrigo M. Zucher*

thanks @rzucher
i have done some improvements to the implementation although it is not going to fix the issues could possibly stop it from getting into that state and return an error instead.
but it is kind of difficult to figure out what is wrong without transaction data being passed to the device.

from the description I think the transaction being created as part of the swap operation is a contract call:

• Does the device enters the review, and user can see the transaction info on device's screen?
• crashes happens upon user approval?

can someone answer this? and maybe provide transaction data. I am trying to reproduce the issue myself and see if there is a sort of debug mode where I can get the serialized unsigned transaction being sent to the device

[rzucher]

1- No, the transaction (entering stx-ststx pool on Bitflow) never actually goes to the device screen, it only appears as generating/generated on Xverser/leather (tried both)
2- crashes few seconds after requesting the transaction

If you want, drop me your email I can share my logs if you think is useful :)

[neithanmo]

@rzucher
Can you share those logs here? so everyone can be aware of the data we are looking at. and we can share here parts of it while going through, anyways you can share that to
[email protected]

[rzucher]

yep sure, I was double guessing if its ok to share it, anyways here u go:
Uploading Logs RMZ.json…

[314159265359879]

@neithanmo

In case helpful in debugging, here's a Leather build that logs the tx before it's passed to the device leather-io/extension#5885

it seems the link is pointing to this issue, no logs file

[neithanmo]

@neithanmo

In case helpful in debugging, here's a Leather build that logs the tx before it's passed to the device leather-io/extension#5885

it seems the dev run(to run in testnet with some funds) does not allow doing swaps which I believe is the transaction type that triggers this issue sometimes

[neithanmo]

We could reproduce the issue and got the testing data we needed. fix on the making via #173

[neithanmo]

I could signed a swap transaction:

so will close this issue via #173

[rzucher]

@neithanmo hey guys, bringing that up , now on Ledger Flex 😭 , it's not going back to fabric conditions, it just doesn't load transactions. but it was indeed working before Nakamoto... idk

[314159265359879]

@rzucher what is the version number of the Stacks App and firmware shown in Ledger Live?

[rzucher]

@314159265359879 24.2

[neithanmo]

@rzucher what is your firmware version? maybe you should update it in ledger live

[rzucher]

@neithanmo OS 1.1.1 , no update available on my side , could developer mode cause any issue alike?

no, I do not think

[neithanmo]

I is difficult to tell, the fix was in the UI section, way before transaction is loaded and parsed
the fix was using a rust library that does not use core::fmt implementation for integer to string conversions, we actually have a test from the blob I got here, and runs just fine on flex device.
Let me check again, but it could be dev mode or something, flex is new and we are still adding support for in other ledger applications we have built

[rzucher]

Just got my device reseted for the 4th time, I've also raised this matter on support channel of stacks community. It happened specifically when trying to use Bitflow's swap aggregator. Isn't it possible to return the app to previous version like you guys did with nano x? (using ledger flex)
