Huawei P8 B151 stuck in Rescue Mode loop.

hi, was trying to uninstall SuperSu and got stuck in Rescue mode Loop,
Phone is Huawei P8, GRA-L09, B151, EMUI 3.1
error message is as follows:
Error!
Func NO : 10 (boot image)
Error NO : 2 (load failed!)
read a page to do a factory reset which ended up formatting my internal storage and still didn't help me.
TWRP can still be accessed when(Vol Up + Power Button are held)
Please help me:crying:
Tried fastboot flash boot boot.img? (Where boot.img is your original boot.img backup you took before rooting etc)
Sent from my HUAWEI GRA-L09

failed Odin flash.. Now can't go into DOwnload mode

so my Galaxy Grand prime was stuck at boot Logo. I tried to flash it using Odin with a Firmware from Sammobile and it failed in the process.
Now I can't go into download mode. The error reads:
" AN ERROR HAS OCCURRED WHILE UPDATING THE SOFTWARE. USE THE EMERGENCY RECOVERY FUNCTION IN THE SMART SWITCH PC SOFTWARE"
I downloaded Kies and it says:
" THE CONNECTED DEVICE IS NOT SUPPORTED BY KIES. IF AN ERROR Has OCCURRED WHILE UPDATING THE FIRMWARE USE THE FIRMWARE EMERGENCY RECOVERY MODE"
so when I tried firmware emergency recovery mode it asks for model and S/N number. which keis rejects by saying it is not correct. Also, the device does not show up in the space where devices which need software update appears.
Any ideas ?:crying:

No fastboot no recovery nothing

I've posted something similar before but now I'm in another situation.
Huawei p10 lite WAS-LX1C432 only boots into error mode with errors: Func no: 14 (iom3 image) error no: 1 (verify failed)
This happened after I messed up Rom installation (https://forum.xda-developers.com/showthread.php?t=3801717) I recovered the dark screen with DC. And now my screen was working again. I could either go into fastboot or error mode. So in fast boot it said that my Frp was locked so I went ahead in hcu and unlocked it. Now I don't have access to even fastboot through the button combination always boots straight to error mode with the errors listed above.
But someone told me that I can use hcu client and that it can do its thing even without fastboot is that true?
How did you recover from black screen? What's DC?
