Hi Sebastian, I hope nothing that follows is misleading, but I'm only a user. The people who do it are far better informed. The phones I've installed on each have their own unofficial development manager. Some mainline phones have an official path. Your 2014 Y550 is well off that track but there's a chap still posting monthly security updates to keep it current, the last was 23rd July. If you look at post 2 on https://forum.xda-developers.com/android/development/huawei-y550-development-t3425524 and click "news" you'll see he's still active. If you want to try, it ought to get you onto Android 7.1.2 - the hardware's too restricted to get you further. There's enough precompiled download files that you don't need to set up his virtual environment and compile from scratch though he shows how. In general and as a summary of what he writes, you need to unlock developer access on the phone, so you can install downloads. You might need ADB or Fastboot from your PC. You need to transfer an updated hardware patch (called Modem in his notes), which is a proprietary Huawei compiled blob for which no source code is released. There's a side-loading recovery system called TWRP specific to the Y550. There's the monthly updated Android 7.1.2 compiled by the current maintainer. There's the Pico or Nano Gapps to gain access to the Play Store, with instructions on how to import it at the same time as the Android file. All the links are in that post and if you follow it in the right order, wiping the instructed bits of the partitions as you go, it ought to give you a working outcome, he'd not put all that work in if it didn't. On the other hand it's a tightrope to walk and it takes a long time. You'd need to be prepared to scrap the phone and shift your SIM to another handset if the process doesn't work. Were it me I'd only set out to do this for bragging rights, if the upgrade actually succeeds.. John.
