Is it possible to wipe Pixel phones?

OpenSource-Ghost

The other day I learned that if I perform full factory image re-flash (unlock bootloader, flash both boot slots with full factory images, relock bootloader) then it doesn't actually wipe phone at all because eSIM part is somehow separate and needs to be wiped separately. What else needs wiping separately? How to truly wipe phone to actual factory defaults, including eSIM?

Hi, actually I did not really take attention to the following paragraph in eSIM management :
https://grapheneos.org/usage#sandboxed-google-play-esim

Privileged eSIM management

By default GrapheneOS always has shipped with baseline support for eSIM, where users can use any eSIMs installed previously on the device. However, in order to manage and add eSIMs, proprietary Google functionality is needed. This is fully disabled by default.

Does it mean in case the phone crash and we have to factory reset / réinstall GOS, the eSIM is still registered inside the phone ?

I mean currently, with my provider, if I cannot access anymore to my phone number to receive an SMS, I can't transfer/register eSIM on a new phone.

I was a bit afraid about it because in case of system crash I thought I would have to register again the eSIM in the phone, but without able to receive SMS, I would have no other way to ask/pay a new physical SIM card to my carrier, wait to receive it, then switch to eSIM from this new physical SIM.

I'm curious to know if eSIM is still there in case of factory reset.

I don't know about your carrier, but at least Google Fi eSIMs cannot be wiped with full factory reset. They cannot be wiped with any "Reset Options". I made a specific thread about it here - https://discuss.grapheneos.org/d/1085-google-fi-esim-not-removed-through-erase-downloaded-sims-in-reset-options

I thought it was counter-intuitive to not include eSIM wipe when performing full factory reset via ADB, but after reading your reply, I began thinking that it was the right approach. It simply should've been worded differently, such as "Full factory reset (does not include Privileged eSIM removal)"

What I want to know is what wipes are needed to fully wipe phone?

Full factory reset
eSIM
???

Bump! Really need to know how to fully wipe Pixel phones? Is it just eSIM + full factory reset or are there more parts (partitions) to wipe?

Esim wipe and full factory wipe should be all you need to do to make sure all your personal userdata is gone, and if you want it to look like you have never used graphene wipe graphenes verified boot key and install the stock google os.

OpenSource-Ghost factory reset and check the box for wiping esim should be enough.
