There is no circular dependency. Notifications and prompts are going to show up on your old iPhone, and you got some 2FA backup codes when enabling your 2FA authenticator.

The user-side will work with all kernels that contain the matching driver, but the user-side will not necessarily work on future Android versions without modification.

by timschumi 2y ago
The kernel side of drivers is already published under a FLOSS license, it's just that the code quality is usually subpar and the important changes are crammed into a tarball together with (sometimes) millions of other lines of changed

GrapheneOS only supports devices that are still supported by the OEM, and they generally seem to have very few modifications that touch on frequently-changed parts of AOSP. In short, they can be relatively certain that nothing will break wh

Yes, donations are cool, without them there probably wouldn't be as many build servers (among other things). However, if donating means that you have to consider your current paycheck size, then it might be more appropriate to put that

To quote from somewhere else: Just to emphasize this for anyone else who is reading this: Please do not feel obligated to donate. Yes, it is greatly appreciated, since it keeps the lights on a little while longer and allows us to provide bu

Apart from the fact that this probably isn't common knowledge, this article is from 2021 (which the OP failed to disclose). Why not be mad at IEEE for a change? They apparently only managed to ban use of the image in April of 2024.

The programmer that I bought was already wired up for 24 series and 25 series chips, so I assume the pinout matches whatever is in that respective datasheet. The 25Q32BVSIG operates on 3.3V, so this particular programmer was compatible by d

It seems like that is no longer the case. I was able to successfully retrieve a non-standard variable using the `UEFIv2` PowerShell module [1] (which is just a thin wrapper around the undocumented `NtEnumerateSystemEnvironmentValuesEx` func

I haven't, and (as I already said) I also haven't tried any of the BSDs yet. I put both on the list of things to try.

Luckily, it was the type of flash chip that I could use an external programmer and a test clip for. I haven't actually ever tried reading/writing through the internal programmer.

I guessed which chip it was (with a little bit of help from leaked schematics for similar laptop models), bought the first programmer that I saw online that appeared to be compatible (anything with a CH341A in it, apparently) and ran `flash
