Wäre vielleicht geschickt sich als #iOS Nutzer*in jetzt schonmal über alternative #Hardware, #Bootloader, #Root und #CustomOS zu informieren. Ist überhaupt kein Hexenwerk und dürfte in den kommenden Jahren wohl anfangen eine größere Rolle zu spielen!

Yas! It finally works, #rustboot can load elf objects, resolve symbols and execute the the init method contained! Took me longer than I want to admit, mainly bc there was a 4byte bss segment I forgot to map correctly in the linker script that was messing with symbol locations of rustboot.
After scouring the internet, we realised that information on Rockchip MCUs is either scarce or hidden behind NDAs. So in our latest blog, David Lodge looks at the Rockchip boot process. He covers the boot order and how to force the MCU into low-level modes for direct USB access.
He also dives into essential tools like xrock and rkflashtool that let you read and write the MCU’s RAM and flash memory.

@Josteglitz @topio ist der #Bootloader entsperrt?
Weil wenn der Hersteller den nicht entsperrt haste nen Problem!

@andreasgoebel ja, musst dazu nen #bootloader auf dem Stick haben und #grub muss den per #chainloading ansprechen!
#Protip: Entsprechenden Stick als einziges Laufwerk bei Installation einer Sesktop-Distrobanschließen oder beim Installierennderselbennfestlegen, dass auch der Bootloader dort installiert werden soll!

Worked the last couple of days on a #bootloader in #rust ; got the bootsector working and even managed to write an clunky elfloader that sucessfully loads ELF relocateables, relocates the symbol and then executes them! Next thing is to rewrite it in a proper rusty style and then integrate it into the bootloader so I can start bootstraping the module system, very exciting!

The second part of my #WinDbg deep-dive into the #Windows #bootloader is up: Get ready for a decades-old registry structure, unique sorting algorithms, and lots of corner cases. The result is a modern Rust replacement for Mark Russinovich's LoadOrder tool: https://colinfinck.de/posts/nt-load-order-part-2/

Neuartiges Erlebnis.
#Stromausfall im Stadtteil. #usv
Neustart.

Genau in diesem Moment #bang krabaff peng, Maschine aus, black screen of death.
Also jetzt ist doch alles kaputt, inne Fritten!?
Nicht nur die Knie werden weich, es zieht einem den Boden unter den Füßen weg.
Mein Kumpel Philipp sagt, Netzteil von be quiet! mit #OPP (Überlastungsschutz) und #OCP (Überstromschutz), Kabel abziehen, 30 Minuten warten.
Alle Strippen dran — und das Ding läuft wieder!
For those thinking of getting a phone and putting LineageOS on it, do note that some phones do not allow the bootloader to be unlocked.
Here is a list of phones and whether or not they allow the bootloader to be unlocked (note, modern phones, rather than older models):
