N5X?
<egg>
yes
<egg>
and guild wars 2 doesn't have recovery codes
<egg>
so I need to get 2 codes out of the phnoe

current status: when frozen, phone starts bootlooping as I enter the screen lock pattern thingy
<bofh^28>
I take it you didn't enable usb debugging in developer options?

might be able to position it in some way to get it to boot (do not jostle)

<egg>
UmbralRaptop: aaaaaaa
<egg>
bofh^28: why are you not here to provide me with liquid nitrogen,
<UmbralRaptop>
egg: eg: having it lie horizontally on a surface
<egg>
UmbralRaptop: it is lying on a frozen burger patty
<egg>
unfortunately it is bootlooping on it,
<egg>
stabbity
<UmbralRaptop>
I mean, it's probably mechanical rather than thermal at this point, so have the phone lying on a flat surface?
<bofh^28>
egg: yeah unlocking the bootloader will wipe your phone if you haven't unlocked it via the OEM unlock
<egg>
bofh^28: how do i know whether it is locked
<bofh^28>
but if you're in the situation of doing an OEM unlock then you can equally well just use adb to copy over the relevant partitions
<bofh^28>
egg: try flashing RECOVERY (NOT BOOT, RECOVERY) as per that page, if it succeeds, you're good.
<bofh^28>
if it fails, it's locked
<bofh^28>
(as in ONLY run fastboot flash recovery)
<egg>
bofh^28: fwiw when the device is booted in the belly-up android with front panel open revealing черенков radiation state it says "DEVICE STATE - locked" at the bottom
<bofh^28>
ahh. yeah, you might be SOL flashing things.
<egg>
not sure why there is черенков radiation,
<bofh^28>
try plugging in a USB cable, booting it, then running adb backup -f myAndroidBackup.ab -all -nosystem
<bofh^28>
tho again you *may* need to unlock it to hit OK to a prompt
<egg>
booting it how
<bofh^28>
oh yeah you can adb shell input to send touch events
<bofh^28>
just normally, to Android
<egg>
...
<egg>
if i could do that i would just be getting the recovery codes and running away,
<bofh^28>
10:11:08 <@egg> current status: when frozen, phone starts bootlooping as I enter the screen lock pattern thingy
<bofh^28>
presumably you can boot it to the screen lock and if you leave it in place in the freezer it will stay booted?
<bofh^28>
this suffices
<egg>
yes but now it doesn't even get that far
<bofh^28>
augh.
<bofh^28>
hrm
<egg>
back to the freezer we go I suppose
<bofh^28>
like basically the idea is to leave it in the freezer but connected via USB
<egg>
aaaa
<egg>
bofh^28: apparently an alternate method is to heat it
<egg>
or insert a US coin in it Ꙩ_ꙩ
<bofh^28>
yeah heating the PCB is what I personally suggest since what you're trying to do is BGA reflow essentially (cc: whitequark)
<bofh^28>
not sure the coin method would do anything
<egg>
bofh^28: compressive maintenance\
<egg>
bofh^28: I could try percussive maintenance too
<egg>
fuck it bootloops right out the freezer now
<egg>
bofh^28: the coin method apparently works with a US dime, 0.01 EUR coin, 0.1 SGD coin, 0.25 THB coin, ...

bofh^28: also the latest bofhsec is in excess of 4 h
* egg|work|egg
almost typoed that as bofhsex somehow O_o
<egg|work|egg>
which would not be that outlandish a typo except my layout is dvorak so they're really not next to each other O_o
<bofh^28>
um.
<egg|work|egg>
bofh^28: does doubling bofh double the length of the bofhsec
<bofh^28>
I *think* they're uncorrelated, but not sure.
<egg|cell|egg>
喵
<bofh^28>
okay I am 99% certain you can have a faithfully-rounded double-double multiply if you have one double-double-double add step for the terms that are in O((2^-53)^2) and propagate its error forwards to the O((2^-53)^3) and O((2^-53)^4) terms.
<bofh^28>
(the last of those terms are necessary only for rounding, but we need rounding here so they're important).
<bofh^28>
sec.
<bofh^28>
okay now I just need to pick a renormalization scheme that provably works correctly, or prove that the dodgy-but-empirically-consistent one I found in a random paper actually *does* work (seriously, the proof is left as an exercise to the reader in the paper)
<egg|work|egg>
bofh^28: actually I have forgotten what result we are trying to prove at this point, aside from the fact that double^k is involved, k > 1 >_>
<bofh^28>
egg|work|egg: quad-double based on double-double has add/sub/mul faithfully rounded (and otherwise behaves nicely) if double-double is correctly rounded.
<bofh^28>
rofl
<egg|work|egg>
bofh^28: wait what, is double-double correctly rounded?
<egg|work|egg>
bofh^28: I thought it was only double that is correctly rounded, and double-double is whatever comes out of linmaaargh
