I just fucked up real bad:

My phone was giving some error about not being able to install an update. Fair enough, i think to myself, so i try rebooting. Still nothing...

I then remember that i at some point OEM unlocked it for some testing, so i start up adb and see if i can connect during the update process. I can't. This is bad: I can't get into my home environment, nor can i connect with adb

Then i try booting into recovery, but instead of booting to ACTUAL recovery, it boots to some custom made "E-Recovery" made by huawei (my phone is a huawei p9 lite), which only gives me the option to download the update, which crashes, and no way of resetting. However, from here, i am finally able to connect to my internal storage via hisuite to make a backup

Next up: Bootloader
So i next load up the unlocked bootloader to try and manually flash the update. That works great, but it still wont boot normally. So i figure: it must think my device is in fact a different device. At this point i'm pretty fucked: Even though i have my data backed up, i can't manually download the update from huawei's site because i don't have the right keys, and i can't download an OTA because their site sucks and half of the downloads don't work, including the one i need. So now i'm stuck here with a bricked phone because EMUI doesn't know how to install an update.

I then did the stupidest thing i have done to date: i wanted to flash a custom recovery image over the "E-Recovery" in order to do some troubleshooting, but instead of writing
"fastboot (mydeviceid) flash recovery recovery.img"
I wrote
"fastboot (mydeviceid) flash boot recovery.img"
Meaning i flashed my BOOT partition with a custom recovery image that turned out to not be able to run. Great! Now i've totally fucked my boot sequence

I can't call their support line either, because as soon as they realize i've tried to restore it myself, and therefor had my OEM unlocked, they basically just hang up.
