Honor 6 Plus Bootloop/Brick. Can't boot into system or recovery or fastboot.

I have a Honor 6 Plus PE-TL10 running Android M. i bought the phone from Japan so probably the stock OS was Lollipop chinese or Japanese variant (not sure). Since there was no upgrade available to marshmallow in original OS I downloaded Indian upgrade file and locally upgraded my phone to Android M india. The phone was running smooth and fine for almost one year but wasnt rooted. So i flashed TWRP 3.0.2 successfully and then tried to flash SuperSU.zip meant for my phone but it failed and phone got stuck in bootloop. Then with no option left i tried to flash stock rom by extracting System, Boot, Recovery.zip from upgrade folder using huawei upgrade extractor and flashing through fastboot. The flash failed and now it just gets stuck on huawei logo right before the booting starts. So I think it aint even on bootloop. Its probably bricked. I cant enter into fastboot or recovery as its not taking any volume+Power key commands. I waited so that the battery drains out and i charged again but still nothing changed. The service center refused to fix it as it is not bought in India.
P.S i think the flash failed cause i tried to flash Indian Rom instead of original Chinese?Japanese?what-so-ever Rom.
Please help. What shall i do?
Thanks

S8+ stuck on boot screen after QF7 flash

I tried to flash TWRP on my S8+ and my phone got a bootloop . Then i tried to root it by Odin(SuperSU) and after the boot screen an error "Verification failed" came. Then I flashed the QF7 BL from Odin in the BL tab( which was a success in the first try), but then instead of a bootloop, the screen was stuck on the boot logo. I cant access TWRP now but can access download mode. I then tried to flash TWRP again but i cant access it( Odin shows successful).
Please help what can i do?? SM-G955F. OEM unlocked.
Thanks.
u need to flash BL,AP,CP,CSC (frimware ) files all together to get back to factory defaults
next time flash custom kernel using twrp after flashing twrp

G930F bootloop, stuck in download mode, only turns on when connected to power

Dear xda-forum,
It seems like I bricked my "new" S7 (SM-G930F).
I wanted to root the device according to this thread. https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-root-android-8-0-oreo-t3840271
Since I didn't turn off the OEM lock, I got the FRP error.
After that, I tried to flash the Stock ROM again, however it just got stuck in a boot loop.
Device only turns on when connected to PC/Charger
Device only works in Download Mode
Device is recognised by Odin
Recovery not working
Binary FRP Lock when trying to flash TWRP
I sadly found out, that Smart Switch with it's Emergency Recovery doesn't work anymore.
Is there any possibility to unbrick my device or do i have to get a new Motherboard?
Best Regards
IJOJOI
Did you try to flash stock rom with odin?
This should be able to fix your problem
I think u need stock firmware and s7 930f pit file it will solve almost all problem related to stock rom
