Tinyhack is a security researcher's blog on reverse engineering, exploits, ransomware decryption, and hardware hacking.
HN links it for technical write-ups like decrypting Akira ransomware files with GPUs, and for a fix for a USB radio dongle.
Some cheap "blue" no-brand dongles don't have USB 3.0 traces:

"Factory reset" is a misnomer, a true factory reset would completely erase the internal storage and replace it with a clean copy of the OS.
If that phone is based on a Mediatek SoC, I believe a true reset is possible - look up SPFlashTool and read about this useful exploit:
