GrapheneOS, Pixel 9a, App, Wasted, Problem with USB-C wipe

GarpheneOSNutzer

Hello,

I have been using GrapeheneOS for a few days and have now downloaded the “Wasted” app. Unfortunately, when I try to reset the phone using the reset function as soon as a USB-C data type is connected, it does not work.

I proceeded as follows: App, Main: Delete data, Settings: USB enabled, but nothing happens when a USB-C is connected.

However, when I create a fake app and tap on it, the phone resets.

Can you help me? What am I doing wrong? What do I need to bear in mind?
I haven't changed any settings for this in the phone itself.

The Wasted app hasn't been maintained in years.
For having any chance that it can work you would have to allow USB connections – which is not a good idea.

KleinesSinchen Okay, is there another app that is equivalent but up to date?

Does USB tethering really have to be enabled? I vaguely remember that it worked without this setting.

GarpheneOSNutzer Even if it was maintained there are other issues: https://discuss.grapheneos.org/d/22341-how-to-set-up-wipe-phone-with-data-usb-attachment

I believe it was also said somewhere by the GrapheneOS account/devs or social media posts that a third-party app built with this type of feature could be stopped before it performs the wipe. (I've been looking for mention of this without any luck so I could be wrong).

Edit (X post)

X post about it being "Insecure and trivially bypassed."

Although it looks like the bypass may have been fixed by the time of the first X post mentioned here userofgos if I understood correctly.

uses the currently completely insecure approach of trying to wipe the device via the device admin API. You can see for yourself that you can simply hold volume down while it tries to while and will prevent it wiping by booting into fastboot mode.

All right, is there a way to wipe the data using the method where I connect a USB data host and a wipe is performed?

userofgos

GarpheneOSNutzer No, not natively

userofgos What approach would you recommend to implement the desired function? Is there an alternative app or something similar?

userofgos

GarpheneOSNutzer as far as I'm aware, there's nothing that provides this functionality in a way that is deemed sufficiently secure and reliable
