I've been recently interested in custom ROMs for the past 2 weeks.
And amongst them, Project Infinity X caught almost all my attention.
The customization features it provides swayed me away. But it struck me hardly in my heart when I checked their device support list on their official website. My phone's model wasn't mentioned there.
Not only that, I tried to search for other Popular ROMs and they too didn't have a version for my exact model.
Then I posted in fb, some dudes told me to try gsm ROMs, or searching for ROMs with the exact codename for my phone. I didn't know what a codename is, they told to install an app from play store and then to check the codename. I still didn't understand what is a codename. Given below is a screenshot taken from that app which I think is the codename.
When I researched about gsm ROMs, I came to know that, almost all the gsm ROMs gonna cause at least one hardware-software integration problem. SIM card, or wifi, battery etc.
Then I came to know about XDA forums. I couldn't comprehend The website's UI at all. What I gathered that, the website was a place for unverified/unofficial versions of custom ROMs. Labeling that as unsafe, I couldn't trust the site.
[ Edit: As xda forum being unsafe, I meant, since it provides unverified/unofficial ROMs made by random developer, It could be buggy and unstable. So much so that it can be worse than gsm ROMs. ]
Only then, I stumbled upon LineageOS, as much as it pained me knowing that unfortunately they too, don't have a version for my exact phone, I came across all sorts of content where the uploader claimed that, they installed an older version of LineageOS in their phone which is also not cited in the official website's page, but the ROM just worked fine for their case. So I was wondering if the same is possible for my exact model. Not only with LineageOS, but with other ROMs too.
My phone model is Redmi Note 13 5g. Came with MIUI, android 13( I think, because I forgot ), then after 2 updates, it is now running android 15 on HyperOS UI.

Damn you, Mediatek !
