Then I suggest to search Google for the combination firmware for your device. Remove frp lock then flash stock firmware.

Not root my device

Okay download the B132 or B125 extract the archive and but the dload folder onto your SD card than reboot while holding power + vol+ + vol-. It should install the firmware right away. This will delete all your apps and app data. When this don't work try reformatting the SD card to FAT32 or use another SD card. That are all option I know for now.

Push via adb a custom recovery : TWRP.
Put a custom ROM on your sdcard and flash it via TWRP. That will also root your device.

Try wiping the phone through fastboot and then try to flash the firmware with stock recovery. So get into bootloader mode (power+volume down untill it gets stuck on huawei ascend logo), connect it with pc and use fastboot commands to wipe all on phone, flash a stock recovery again with fastboot recovery, and then try to isntall the firmware with the recovery.

Twrp bootloop

Hello,
i just unlocked bootloader and installed twrp and it all went fine..
until i wanted to fully wipe my device, i did this via twrp.
after 20Minuts, nothing happend, the bar was still white and gray (not even a little bit blue)
and it kept stuck on ''twrp formatting data using make_ext4fs function''.
i knew this wasn't a good idea, but i decided to turn off my phone,
and now, everytime when i turn it on on the normal way it just redirrects me to TeamWin in a bootloop.
even if i want to go to recovery mode i keep stuck in that bootloop, so there is nothing i can do right now, i only can stick at Fastboot Mode but nothing else,
Is there any way to fix this problem?
Using ASUS ZENFONE 2 551ML
I hope you did a backup of your system before? Otherwise just download the latest full image:
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-WW-2.20.40.174-user.zip
place it on your internal sdcard (via adb push) and then flash it normally with TWRP. Please note that the procedure can take up to 30 minutes, where the formatting is the procedure taking the longest time...

but i cant use twrp on my phone because its stuck in bootloop, or what do you mean? (english not my main language)
please give me some proper step by step instructions, i would really apreciate that!
thanks anyway your awesome!
Man, I misread your post, sorry...I thought you could boot only into twrp
If you still have fastboot, why not flashing twrp 2.8.x.x?
Code:
Fastboot flash recovery nameofrecovery.img
Fastboot reboot recovery
Otherwise you could flash stock system with this guide: http://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256
It's a lot to read
wow, that is something really helpfull, there is still hope to revive my phone
i'll let you know how it turnt out xd
thanks alot!!
i fixed recovery mode, so thats already one step further. Oefff @TheSSJ thanks for the help.
But now i get some other problems, when i try to wipe my phone i get the error like ''unable to mount /data'' and ''unable to wipe dalvik''
and all other kinds of these errors, i get the same problem when i was installing rom. isn't there anything or a way to fully wipe all this **** so i can install a fresh rom.
i flashed custom rom and this is error log i get. its all full written down.

Seems you don't have a WW image installed, do you have a CN Software? Then you need another Software of course
what do you mean with ww & cn software?
sorry but im new in this.. but im really interested so can you please explain a little bit?
how can i get this other software! thanks!!!
Where did you buy your Phone? what does the packaging state? WW, CN, TW, etc? These 2 letters must be written in uppercase somewhere, then we will know which software to flash, there is a check where your phone's software is compared to the zip you are trying to flash:
assert failed: getprop ("ro.build.asus.sku") == ''WW''
Which TWRP did you flash?
ohhh yes, i do have CN software Probably, as it is buyed from china.
Where can i find this other type software?
thanks!

There you go: http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-CN-2.20.40.159-user.zip
I think flashing will still fail though...but pls try first,maybe it'll work
i tryed it, i get the same error :/
Update: i changed from CN to WW.
Because of this i reflashed to twrp 3.0 and it works properly and now wiping shows no problem anymore.
I also got the WW ota zip but dont know how to install that.
Anyway, i tryed to install xaosp rom (even if my ota is still CN)
And it showed no problems at all!
BUT when i tryed to startup my phone it sticks with the asus logo and wont go any further, not a bootloop, it just sticks at the asus logo.
We are Always getting more and more steps further into fixing my phone, thanks for that @TheSSJ were almost there ?

You could try flashing cm13 first and then xosp:
First wipe data/cache
Then flash cm13
Boot up and hope that it works
Reboot to recovery
Wipe data/cache
Flash xosp and maybe a kernel that fits (FlareM?)
Boot to system again

HTC One M9 Hard Bricked + corrput download mode

Hey there!
I had problems with my HTC before but I managed to fix it by unlocking bootloader and reflashing the stock recovery.
Then after a few weeks my HTC suddenly rebooted itself and got stuck in a bootloop. It then said Phone Storage is encrypted and decryption failed. So i went to recovery mode and did a factory reset which did not work.
Right now bootloader says this: "STATUS:MODIFIED / RELOCKED / S-ON / SECURITY WARNING"
When I try booting to download mode it says: "FAILED TO BOOT TO DOWNLOAD MODE" with the security warning
When I boot to recovery mode it says: "MOUNT /CACHE FAIL" , "CAN'T FIND DEVICE NODE FOR MOUNT POINT /CACHE", but I can navigate normal through its options.
When I try applying an update from SD card oder sideload it always fails and puts out more "FAILED TO MOUNT /CACHE /DEVLOG..." warnings.
When I try to apply the RUU.exe it says my phone isn't charged more than 30%.
fastboot getvar all in bootloader mode wont say anything except my SN.
Wipe data/factory reset or wiping cache will fail and output more "CAN'T MOUNT ..." errors
I can't install a new recovery like TWRP since my bootloader is relocked and download mode is inaccessable.
Also, if my phone is connected to any power source and I power it down it will show the charge animation for a second and hop right back into bootloader.
Anything else I could try?
Thanks (can't put in any images because i just registered..)
I have same porblems but i have the phone unlocked with s-off. Can you help me to fix it? thanks.

I hate to say it, but you might be having some hardware issues with the motherboard. I'm not sure what solution (if any) is available: without download mode or recovery (and a locked bootloader), you may well be out of luck. I'm sorry.
