Crack executables with gdb?
Hi, I'm a beginner in hacking and I have some Linux executables(Elf) from which I have to extract some data, the first one use several system sleeps and very long loops to avoid this data print, the data Is generated procedurally so I cannot just search, find and decode It in the binaries, so my first question Is, Is It possible to use gdb to skip sleeps and loops and how can I do It? The second executable gets an input and does some operations on It, when I try to reach the part of code that I'd like to execute I get segmentation fault error, It seems that the code was written to have this error on purpose. Reading the assembly code I found that segmentation fault is generated on some variables copy in or from DWORD PTR and BYTE PTR, I've also noticed that most of the times the pointers point to nothing(0x000...), In this case what should I do to get over this error and execute the code I want? Note that I don't have debug symbols and source codes, just the elfs, both doesn't have canaries + I have installed gef to have some additional help.

Forgot my pattern (Poco F1, USB debugging enabled, bootloader locked) (will remove the post if it's against the rules)
A very desperate plea for help:
tldr: need to bypass pattern lock without losing precious data.
I changed my lock pattern a couple of weeks ago and forgot it since I only need to use fingerprint and face ID to unlock; I know very dumb!
I woke up one day to find a MIUI update that requested a restart. I've been locked out of my phone for four days and I can't even begin to fathom the amount of irreplaceable data I'd lose if I wipe the phone; which is seriously depressing me.
If you know of ANY solution to save my data or bypass the pattern lock please comment.
The phone is Xiaomi Poco F1 on android 10 with the latest MIUI (12.something). USB debugging is enabled, no root, bootloader unfortunately locked.
ADB doesn't read my phone when I type "ADB devices" nor connect through wifi.
p.s: please spare me the "no there's no solution you have to wipe it" comments.
