A: Yes. Once unlocked via SigmaKey, the network lock is removed permanently. You can root, flash TWRP, or install LineageOS without relocking the network.

Follow this sequence precisely. Do not skip steps.

| Pros | Cons | |------|------| | ✅ Fast unlock (1–2 min if supported) | ❌ Requires paid SigmaKey box (~€200+) | | ✅ Works even after factory reset | ❌ May fail on latest security patches | | ✅ No need to request code from carrier | ❌ Some versions need test point / disassembly | | ✅ Also fixes FRP, IMEI, dead boot | ❌ Not beginner-friendly – risk of brick | | ✅ Regular updates for new devices | ❌ Void warranty |

This method works as of SigmaKey v. 2.38.04 and later.

: Once the correct VCOM drivers are installed, SigmaKey identifies the device quickly. The unlock process itself generally takes less than two minutes. Reliability
