Huawei Y625 Stuck on Boot Logo

Dear Sir/Madam
My Huawei Y625 has been bricked I suspect.
Basically my rooting software Kingroot constantly kept crashing so I rebooted my phone. Once that happened it would not go past the boot logo.
I did not install a recovery as my phone did not have one at the time I rooted it, so I only have access to the stock recovery.
Is there anyway I can flash my stock ROM onto my Phone using my Computer or my stock recovery? I am running Arch Linux.
I have tried a hard reset as well btw.
Thanks.

Huawei P8 Lite ALE-L21 stuck in black recovery bootloop

Hey there.
I've really f*cked up the Huawei P8 Lite of a friend, when trying to root it with CWM and Supersu package.
He once tried it himself, but that ended up with a new paperweight and he got a new one from the seller.
The old one could boot to TWRP, but ended up with a bootloop when trying to install supersu.
The new one can't even get into TWRP or CWM! Yes, both devices were OEM-Unlocked.
The new one shows a blank screen right after booting to recovery, but i was able to get to system and fastboot.
But after installing CWM (because TWRP didn't work either) it just goes blank after oem logo and adb tells me it is in recovery mode!
Code:
C:\Windowws\System32>adb devices
List of devices attached
W3D7N------------- recovery
So every time i try to power the phone on, it boots straight to recovery and same outcome on adb.
It is possible to reboot it with adb in recovery but it does nothing. Just goes to recovery.
Cant get into fastboot either. Adb on system not possible and key combination (tried VolUp+PWR VolDown+PWR and VolUp+VolDown+PWR).
I don't know..
Have i made a second brick? Am I screwed?
Because i don't know if the seller will give my friend a new one AGAIN...
Have i f*cked up?
Please Help!
UPDATE:
I played a bit around with the adb/recovery and i rebooted it somehow into a mysterious mode...
It showed up as "Red is the Red" in chinese symbols in the device manager..
That is quite mysterious and a lil bit scary... I wasnt able to do anything, tried drivers but no response in fastboot/adb
UPDATE II:
THANK GOD!!!
I somehow got it right with adb reboot bootloader!
You don't know how glad i am
So i would say: SOLVED!
How did you get it back to fastboot?

No Reboot After TWRP Flash

Hello, i had a lot of troubles with battery drains recently, by curiosity i wanted to restore my stock backup.
So i did and the phone was stuck during rom boot.
So i wanted to go back to TWRP to fix things but instead it went back to stock recovery.
Okay, so i wanted to flash TWRP again but after flashing the recovery.img,
nothing happens when i enter fastboot reboot
I forced shutdown and re tried many times with other twrp files, always the same issue i cannot reboot with the flashed recovery ! ! !
please HELP :angel:
To boot to recovery, shut down the phone, press volume up + power button, when the phone vibrate release the buttons and it will boot to recovery.
The command "fastboot reboot" will just reboot normally the phone.
sorry but my problem is that i cannot reboot in twrp anymore, it always reboot on STOCK recovery !
dunno what to do i got to meet foreign customers tomorrow without my phone i dunno how i'll do, so unlucky it happened to me today
i even tried flashing on another computer, and trying to restore with stock recovery or huawei app but none are working.
to make it clear, i can just fastboot.
so what should i flash to restore/unbrick my phone ? don't care if i lose data, just need to call tomorrow !
edit: some folks say to put update.app in load folder on sd card then boot with the three buttons but which update.app file should i copy ? i got a VNS-L31 should the SD card be in FAT32 ?
Are you sure you flashed TWRP? Try to download it again and flash it from fastboot mode.
yes sure i did it like 20 times this afternoon, i'm trying to fix it for 5 hours lol
in fact i just was able to boot the restore .app while booting with the three buttons, it's installing updates, hope it will fix all the partitions/recovery/boot/system... and all those necessary stuffs
edit: finally huawei animated boot logo is showing UP !

i was using meticulous TWRP v3 and some of his builds for several months and i had trouble with those roms.
so i restored my stock backup and everything was not working anymore, each i tried flashing it always went back on stock recovery a every reboot, impossible to flash twrp anymore...
looks like the phone is stuck in a boot loop lol pfffft
edit:
FYI what i just tried is restoring this image http://consumer.huawei.com/lk/support/products/downloads/huawei-p9-lite-lk.htm (the first one ASIA) but the phone is still booting looks like a fail, could it be incompatible ?
I see.
If you managed to restore with the update.app and the 3 buttons, everything should be fine. It will take some time to boot up, so just wait for a while. Also the bootloader probably re-locked so you will need to unlock it again.

it can relock ? i will check !
if it does not work should i fast boot flash system.img, recovery.img, cust.img, cache.img and boot.img ?
I think the best thing to do should be a factory reset from recovery, stock is fine, then reboot and wait for 15-20 minutes. If the update.app succefully installed there should be no problem

If you don't have to option to factory reset then you must be on eRecovery

Can only boot to bootloader

So I unlocked my bootloader on my Huawei P8lite ALE-L21 yesterday and flashed twrp recovery. Trough twrp I tried to root the phone by flashing.. It sort of failed and I got into a bootloop.. Then I tried to get out of the boot loop by trying methods I found online. Other's did nothing so I tried to flash boot, recovery, system images.. Now it won't get in a boot loop but I get the huawei logo for 3 seconds and the phone turns off. I can only boot in bootloader.. Is there any way I could still make it work or is it completely lost now?
Update: I flashed Boot.img and recovery.img again and now im stuck at the point where huawei logo appears, but not turning off phone. I am also able to get to recovery now.
Update2: I flashed a different system.img now and suddendly the phone started working.. Problem solved I guess.

Hard bricked P9 Lite- please help!

Hello,
I've bricked my Huawei P9 Lite (VNS-L21). It dont has any system. Fastboot unlocked and I can get into it. And now the biggest problem -> PHONE HASN'T GOT ANY POWER OF BATTERY! It cant get into recovering emui (3 buttons method) because it says that it hasn't got energy! I tired flash UPDATE.APP via fastboot but it stuck at "Your device is booting now..." I remember, that when I tried flash Elemental V3, it shows me black screen!!!! No bootloop, no working- BLACK SCREEN! Why? How can I unbrick my phone? Or how can I charge it? I think it's the biggest problem...
What did you do to it before that happened?
I flash Elemental V3, link: https://forum.xda-developers.com/huawei-p9lite/development/firmware-emui-5-1-huawei-p9-lite-t3768973 but I think that I did something wrong.
have you tried d-load?
Yes, it can't get into it, because the battery hasn't got any power ;/
Is fastboot working?
so, you wrotte :
And now the biggest problem -> PHONE HASN'T GOT ANY POWER OF BATTERY!
Yes, it can't get into it, because the battery hasn't got any power ;/
Maybe you just need a USB cable ?
It dont charge...

Since this happened, you was success? I have similar problem, device is booting and stucked in this point. dload, fastboot can not started.
Can you still access eRecovery? It is possible to install stock ROM via Firmware Finder, changed DNS-addresses and eRecovery: https://forum.xda-developers.com/showpost.php?p=76450388&postcount=20
