Samsung Galaxy S3 Neo (i9300i) in bootloop after attempt to uninstall Xposed manually

Greetings,
I have attempted to install a version of Xposed that wasn't compatible with my Android version (I only found that out later), and after trying to install modules I decided to uninstall it. I tried doing so through the app, but got an error saying there is no backup (or something of that sort), so I Googled for a way to manually uninstall the app through TWRP. After deleting and renaming some files following a post by someone on XDA (I'd attach a link to the comment but I don't know if I'm allowed), I restarted, only to find out it gets stuck during the Samsung logo and goes into TWRP (repeats every time I try to turn it on).
I tried reflashing the ROM I currently had (CyanogenMod 12.1) and flashing to Motion ROM, but both failed to install - as soon as I started installing them through TWRP, a black screen appeared and TWRP restarted. I also tried reinstalling a (supposedly) functional version of Xposed but that didn't work either.
Is my only option erasing all the data inside and reinstalling my previous ROM? Or is there any way to fix this?
