# HMD Global/Nokia
- Verdict: ** ⛔ Avoid!**
In the flaming pile of HMD's "great" decisions to improve Nokia, one stands out more than others: They decided to follow the fresh "lock the bootloader" trend.< br / >

Well, anyway. Models released before early 2019 can request unlocking using Hikari Calyx's unofficial service [hikaricalyx.com][hikari-service]

And for some other models, Hikari Calyx has a repo with prototype ABLs. [fih-firmware.hikaricalyx.com][hikari-abl]

Models 7.2, 8.3 and 5.3 can be unlocked offline, while others may require HMD Device Kit **which is not public and requires a service account.**

As for Windows Phones, most models have an [unofficial method][lumia-unlock] of unlocking, which is supported by most Nokia Lumias, except for the 620, 720, and 1320.
