Poco is unlocked.
There is no brick on any, they're boot loader bugs and unrelated to the exploit. Recovery "reboot" was used.
You need to modify it to root, the example only crashes the kernel.
Good news for reusing old phones and taking control.
*as in replace
Backporting an old kernel should be possible, but the only indicator is the system update changelog that explicitly mentions it, I rarely see CVEs mentioned in changelogs on any smartphone. A tool to test the vulnerability is the only way.
Any compromised app on the Play store or external can get root access instantly, but we can still rely on trust and audits when installing apps which should always be the rule.
I suspect that this will be added to all Google Play integrity levels, limiting many apps from being installed on unpatched phones in the future.
That's not the case with browsers with random sites and ads which is hardly avoidable, having any sandbox escape is now more severe considering that it bypasses the app container. It's similar to JailbreakMe on iOS [0]
Two boot looped, I had to enter recovery and the other just powered off [0].
The demo modifies the wallpaper on supported Pixel devices.

Tip: Install a Chromium flavor browser (Chromite) separate from the main browser.
Disable Javascript and hardware accelerated video decoder (commonly exploited) from the flags page and enable reader mode to fix broken JS-dependent websites when browsing blogs and random sites on your personal devices, else dedicate a tablet.
On my Lenovo laptop, fixes that would take over a day to enable and patch on most distros:
- Wake from sleep
- Nvidia GSP firmware workarounds and correct version OOTB (proprietary)
- Mouse lag/jitter
- External display hotplug
- DDC/CI over type-c
- Embedded controller power profiles from taskbar with correct TDP limits for CPU/GPU
- Battery charge limiter support right from KDE settings
- Working `switcherooctl` in hybrid graphics mode on AMD
- Firefox with video decode acceleration (YouTube) on almost all GPU models
Currently using BPFland which makes multitasking as responsive as idle while compiling Yocto/Chromium in the background.
Windows, Mac (mini M1), and kernel built-in scheduler Linux jank and become almost unusable (Ryzen 5800H).
There were no mentions of requirements for 802.11r in the comment. You removed "much faster than K/V." from the quote. "only" was referring to 802.11r exclusively. You can have the same results with different channels with K/V, provided that the clients support it as the rest of the comment mentions.
802.11r-only on different channels is ineffective for devices without K/V, since the reductions are insignificant.
You will be shaving 100ms from a 700ms delay on scan and association, compared to no-scan association which is around 20ms, hence the 75ms note.
And even then, FT is only needed for short buffer streaming like VoIP and VoWiFi. It's more important for WPA3, since handshake roundtrips are even longer (~300ms) which can degrade video/voice internet calls with a lengthy time to recover and complete silence for second or two on VoIP, it's not really needed for the average user back when WPA2 was standard.
Android and iOS will first scan on the same frequency, then rotate through the channels, which is now even longer on 6Ghz capable devices with the total number of channels.
The transition time is significantly faster with equal channels on most hardware, this is where 802.11k helps with different channels, especially in iOS. Without it, they cache scan results provided that the farthest AP is detected, this rarely happens since the scan time is so short.
Scanning different channels while connected causes large amount of jitter on station optimized WiFi SoCs, affecting VoIP on mediocre connections while the user is moving and actively losing signal, so its done as quick as possible, often missing many beacons. They can scan longer on the same channel without degradation. [0]
Without K/V, iOS/Android goes to the extent of doing frequent rescans on low network activity on body movement, you can install a Wi-Fi diagnostic profile to view the current activity on iOS, logcat on "fused" for Android.
The suggestion doesn't bash on 802.11k/v, it's just a compatibility alternative, considering that very few clients support it, let alone off the shelf consumer AP support.
> Setting them to the same channel will cause the APs to interfere (when they can't "hear" each other) or block each other from transmitting, or both. You set APs near each other so they are on non-overlapping bands. Always.
> This is basic WiFi networking 101
This is only true under large air time traffic and in large scale indoor setups. Not satellite APs that are far. Qualcomm, Mediatek and many systems implement their own spatial reuse technology. WiFi 6+ introduces BSS coloring for channel width overlaps to further improve speeds on mixed traffic, not to mention the generally low penetration / TX power of 5Ghz+ on SNR.
>> Samsung is known to push protocol support early: 802.11r in 2013
> 802.11r was released in 2008 and rolled into 802.11-2012.
> Also, the iPhone 5S (2013) has 802.11r support.
The Samsung line in the comment was referring to Androids, many Android didn't support these until 2020, some non-flagship still don't (disabled), Samsung was notable to include it early, there are three paragraphs underneath referring to old phones and smart TVs, both Androids. It is not enabled by default on many off the shelf APs for these reasons.

It's an interesting setup, looking forward to an update.
On iOS, equal channel with correct ESS will switch liberally. On Android 14+ with Broadcom chip it will start conservative, then switch liberally after the first poor signal switch-over event, up until disconnection.
Android (Pixel/Moto) will never switch (even with K/V) on large network activity, only VoIP/video call. It depends on vendor implementation. [0] I use "dp.logcatapp" log reader while roaming, "com.android.location.fused" can be used to show score and current load.
Samsung is known to push protocol support early: 802.11r in 2013, 802.11w 2015, some models do not use Android's default connectivity manager.
To add, WPA3 with 802.11r is known to have issues on Apple hardware before 2021 on all iOS versions, many Android devices, especially smart TVs don't support it, will not connect or are unreliable (protected beacon frame), can be searched in buried report results at OpenWrt forum mega threads and Ubiquity. WPA2+FT and forced MFP with a long password is a safe alternative. 802.11r use PMK push on WPA3 compared to WPA2, which was known to be problematic on older hardware.
802.11K/V is more suitable for campus and load balancing, tuning it based on RSSI and station metrics is very difficult, enterprise hardware rely on network traffic and air time.

I found a workaround by unplugging and replugging as quick as possible, it goes back to ~5.0V.
Tailscale works with "--tun=userspace-networking" [1].
I had it running on an old phone as a Frigate server with a solar powerbank in remote area, using the 4G as a failover. The uptime is almost a week without solar. Attiny hooked to the power button and a photodiode on the phone flash [2] (blink per minute) used as a watchdog for shutdowns/hangs to hardware reset. The button cap is removed without disassembling the phone.
Old phones are still more efficient than most off the shelf SBCs, especially under load. ~3W compared to 12W with a Pi5 in the same performance ballpark.

Currently using https://isit.mooo.com for daily usage and http://hnapp.com for advanced search.
I paid $200 for a Moto G85 5G with 12GB RAM, 256GB storage last year.
Alternatives in the same range: CMF Phone 1/2 and OnePlus Nord CE4 Lite 5G
Android phone to android tablet USB tethering is also local MAC and non-functional.
It now appears as eth0 and routes created only after turning off the Wi-Fi, DHCP is obtained regardless.
ECM scores 270Mbit, RNDIS 150Mbit.
Mobile hotspots/dongles with MAC address modification should work. (currently detected as usb0)

Started with Android 4 KitKat, stuck with Linux kernel 3.4 :)
5.4mm thickness, 3GB RAM (enough for 32-bit), 2TB SD card works, watching movies/shows with the AMOLED look as good as a recent OLED TV. Truly ahead of their time.
SDR content with mDNIe dynamic enabled comes surprisingly close to HDR content on an HDR display, colors can be a bit too staturated though.
After a decade, the battery lasts a week for daily hour e-book with black background. 3 hours of video playback. However, it restarts at 30% battery when running at full brightness with a white background. Disabling Wi-Fi significantly extends standby time compared to modern hardware.
Caveats: Slow web browsing and no H.265 hardware decoder. 1440p H.264 60Mbit is the max (Display is 1600p). Most content providers and streaming services are slowly moving away from AVC, so it's stuck at 720p H.265 on CPU.
Back in 2014, I couldn't have imagined using hardware that was over a decade old.
The Go binary runs everywhere including most NAS except at least 1GB RAM is needed for decrypting the master key due to Argon2.
E2EE solves all of these issues as long as it's open source and reproducible.
Efforts like these should be praised.
Since dart/flutter is multi platform, using Random.secure for animation has it's own performance issues with interfacing host entropy RNG.
The majority of Dart/Flutter users are creating UI apps.
Few browsers with security policies and OS combination does not allow access to the entropy with Flutter Web in which Random.secure will fail, this isn't exclusive to Dart/Flutter. [1]
NaCL [0] offloads these concerns for developers, especially indie/startup.

DTD is local host or over SSH due to the unecrypted websocket.
Browsers block unsecure WS over HTTPS. The key generated is for tagging multiple instances per IDE not security.
Random is instant and is used for runtime collision prevention and performance especially UI, not uniqueness, PRNG is not truly random anyways.
Random.secure has a large overhead accessing OS entropy and isn't always supported. [1]
Go 'math/rand', python 'Random', C# 'Random' to name a few are also not unique or safe for crypto.
Their secure equivalents: Go 'crypto/rand', Python 'SystemRandom', C# 'RNGCryptoServiceProvider'.
This isn't a Dart or Flutter issue [0]:
"A generator of random bool, int, or double values.
The default implementation supplies a stream of pseudo-random bits that are not suitable for cryptographic purposes.
Use the Random.secure constructor for cryptographic purposes."

The domain redirects to github due to the changing commit hash raw URL.
You also have to cross-check the 4 kexts checksum with the origin in the OpenCore ISO, including binaries in other projects like OSX-KVM. Thankfully there are no binaries that require reproducible build setup.

The original intent is to avoid custom hardware configurations by using PVE as a layer. Hackintosh on bare metal can take days to figure out on new hardware.
At 60%, the battery will drop to 45% percent before recharging to the specified percentage for coulomb counter drift compensation.
Most lithium UPS avoid this by using LiFePO4.
Moto G04 with 128GB Storage (UFS - 400MB/s read/write), 4GB RAM and 2TB capable SDcard UHS-I slot is just 90 USD.
ZRAM is enabled by default at 2GB and 2GB storage swap, it's adjustable under "RAM boost" setting.
Disabling the app background killer is one toggle away for Termux.
No root required.
Wi-Fi does around 350Mbit with no buffer bloat, and supports simulatenous softAP and station mode with a dedicated DHCP by enabling hotspot without mobile data. This is useful for out of band management, e.g if Wi-Fi AP goes down, there is a small hiccup though.
You can combine Speedify and Tailscale (for NAT) to have 99% uptime with seamless failover since there is a mobile modem in there. ;)
The Type-C port is dual role and will charge from a powered hub in host mode. However connected devices power is disrupted for a split second if the charger is removed, so the phone isn't really a UPS for external peripherals unless you don't mind the brief reconnection.
I do hope a Pi A+ or something similar and popular exist in the future at a reasonable price, considering that we have phones that are cheaper than the Pis while missing GPIO but adding camera, speaker, screen, case, charger, LTE, and a headphone jack which was also removed on the Pi 5 (USB DACs aren't consistent with pipewire).
Mini PCs vary and they aren't really portable, hard to setup headless, especially projects utilizing an easy DIY approach like the Pi-hole or kit/pre-flashed SDcards.
For comments comparing a new Pi with used PC: used Pis exist and are a lot cheaper after shortage.
Note that save data is in browser local storage, no way to export for now.
Runs well on recent Android tablet and Chromebook with mouse, despite a debug build which affects performance.
8 FPS Firefox, 40 FPS (original game limit) on Chrome.
Like OpenTTD, multiplayer doesn't work since there is no websocket server support yet.
