on my last post I wrote device is a redmi 9c. Turns out it’s a redmi 10c and the custom ROM I wanted to install https://xdaforums.com/t/rom-13-unofficial-lineageos-20-0-unified-for-redmi-9a-9c-10a-blossom.4609367/ won’t work.
Anyhow, to unlock the device the official way I have to identify to their services through a phone line, not internet, and purchase a sim card, which I’m not going to do to experiment with this device.
I have no use for the stock software in the device and I’d rather have anything foss that works or kinda works.
If you ever experimented with this particular model or know what could work, feel free to post an answer.

Your phone has a snapdragon which is very popular chip to make ROM for but generally hard to unlock unofficially -not impossible though it’s possible there is a workaround by now for your specific chip - on the flip side mediatek devices are less popular due to them refusing to provide the source code but to their partners. however they are well-known to be easy to unofficially unlock due to some vulnerability -in the bootloader- that they refuse to patch.
I did a leap of faith and I unlocked my phone unofficially (mediatek) but if you decide to flip that coin think hard about it and make sure you are well informed (like using your specific phone code name instead of brand name ex: instead of redmi 9 say “lancelot”)
