ICCID activation was once a popular way to work around carrier locks on iPhones. If a previously activated device is jailbreakable, its activation ticket can be backed up and restored after a reset, iOS downgrade, or DFU restore. The ticket is device-specific and only preserves activation on the iPhone from which it was saved. Here I use my iPhone 5s (A1453, au/KDDI Japan model) as an example.
The 360V6 ships with an A/B dual-partition design, but after flashing OpenWrt, sysupgrade only writes to the current partition while OEM remnants on the alternate partition cause upgrade failures. After figuring out the bootconfig slot mechanism, I submitted dual-partition upgrade support to OpenWrt upstream, which has since been merged.
A memory-modded 360T7 ran fine for years until I flashed OpenWrt's bl2 and fip, which bricked it with dram size: 0MB. Every rescue package found online failed. Eventually I traced the issue to a DDR3 frequency mismatch in the ATF source, compiled a custom bl2, and recovered the router via UART.
Running a BitTorrent (BT) or Private Tracker (PT) server at home can be challenging if your home network doesn’t have a public IP. Public IPs are essential for direct peer-to-peer connections, which significantly improve torrent connectivity. However, with the right setup, you can achieve similar connectivity and even gain extra benefits, like access to IPv6 peers, by using a VPS and WireGuard.
The 2012 Mac Mini Server remains a popular choice for Proxmox Virtual Environment (PVE) installations. This model stands out for its upgradeability: it allows for both memory and storage upgrades, making it particularly versatile. It’s also the last Mac Mini model with this flexibility, as the 2014 model saw soldered RAM, limited CPU performance, and eventually, Apple’s transition to ARM architecture in later versions, which limits virtualization capabilities.
