P9 EVA-L09 problem with software

Hi, I've got a problem with booting and generally doing anything on my phone - only erecovery is working right now. I've tried to install 7.0 update - and it got the NRD90M rom instead of b361 or b360 - then I've tried to do an update via dload - however, it failed - I read somewhere to flash extracted files like system, recovery (and sth else) via adb - i did it and now i've got nothing. Are there any posibilities to get my phone back? to install software? I've tried to install twrp but it also failed - i mean i can use adb in erecovery mode but i can't turn twrp on - 'device is booting'... Any ideas? (Sorry for my english)

Try to use the Multi-Tool for team MT,maybe it will help you to unbrick your phone,i`ve used yesterday to unbrick a Honor 5C NEM-L21.You will need the update.zip for you phone and Huawei Update Extractor.
Or try DC Phoenix

P10 bootloop problem

Hi there guys,
I'm having p10 VTR-L29, last software was C432B185, i tried to update it to oreo, dload folder metod.
It failed, now i can't connect to adb via fastboot, tried multiple version off software (B164, B175, B180, B185) none of them worked, again metod dload folder because that is the only way i can even try.
When i load into fastboot there some messages coldboot.
Any idea how to fix this problem and load any firmware?

Please help .. black screen

Hi, i managed to downgrade my p20 pro from Emui 10 to 9.1 and i tried to downgrade it even further to 8.1 using Hisuite software, i used hisuite proxy and firmware finder to get the firmware needed, after installing it a message popped up in my phone showing an error in the installation and that i should boot in Erecovery (seems a bad firmware) when i clicked the phone went black, i can't boot in any of the fastboot nor recovery.. i attached a screenshot it seems that the phone is identified on the pc. is there any kind of solution to enter the recovery so that it can be recognized on Hisuite please ?
ps : the device seems in fastboot but doesn't turn on
