I am making unofficial iodéOS builds approximately monthly for the following OnePlus devices and host them on the iodéOS section of the LineageOS for microG download server, with OTA update support included:
| Device | codename | iodéOS | OTA Updates | Links |
|---|---|---|---|---|
| OnePlus Nord N20 5G | gunnar |
v7.x |
YES | Download Installation Guide Upstream Source |
| more coming as needed: - OnePlus Nord N200 (?) - OnePlus 12? |
To install, use the Download link and download all the files for the newest iodéOS version and follow the instructions in the Installation Guide link, but use the downloaded .img and .zip files instead of the LineageOS files.
The main motivation for these builds are the device availability in the USA (which make them great candidates for me to sell at https://openmobile.us), the official build availability from LineageOS, but the lack of official iodéOS builds.
NOTE: Bootloader re-locking on OnePlus devices risks bricking the devices, so it isn’t supported as far as I know with any custom ROM. As with all modern Android systems, your data is encrypted and safe unless your unlock pattern / pin is compromised, which is the same regardless of having a locked or unlocked bootloader.
The theoretical risk of an unlocked bootloader is that if some malicious and technically advanced entity gains physical access to the device then you can’t be certain if they possibly tampered with the system in your absence. In that case, if you feel your device may have been compromised, after you regain control of it you should reset the device from System Recovery before booting to ensure any malicious process doesn’t steal your data after boot.
To be clear, without physical access, it is not proven, as far as I am aware, that an unlocked bootloader poses greater threat to your data being compromised than an unlocked bootloader.
