Hi!
I've got a problem with my Mate. I wanted to update my smartphone to Nougat (My Mate is C636 B170) and I updated to B180 using Firmware Finder from Google Play without any problems. Then, I choosed B193 (I think) and something went wrong. Now i can only enter recovery, eRecovery or fastboot. My phone isn't rooted and bootloader is locked. I've tried to use rayglobe knife and SRKTool. Nothing helped. I can't flash via dload, update just doesn't start. In DC Unlocker I see, that my firmware is C900B172 (!) I don't know what to do know? Any ideas? (sorry for my English)
Unlock your bootloader and then unpack with Huawei Firmware Extractor from UPDATE.APP of B172 the following files: boot.img, recovery.img, recovery2.img, system.img, userdata.img and fastboot every single one into your device with the commands «fastboot flash boot boot.img, fastboot flash recovery recovery.img» and so on. It should be back on track.
How can I do that? I can't run my phone, so I'm not able to get Product ID and my Huawei ID that I made to get this code has only a few days. When I connect my phone in fastboot mode to PC and run DC Unlocker, there is only FRP erase and Network unlock whick is inactive.
EDIT: BTW, any B172 link? I can't find any active. My Mate is L29 of course.
Ok, I think I'm one step closer. Earlier I didn't see that there is a Mate 8 in "Select model" in DC Unlocker. Now, the problem is that when I click "Read bootloader code" response is:
Reading bootloader code...
unknown error (359)
What can I do with that?
Hello!
I'm still trying to fix my Mate. I know that flashing B320 via DC Phoenix but B320 is impossible to find :/ Can I flash any other firmware?
Now, when I reboot my device this is how it looks like :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I can enter into fastboot mode, so I believe that there is still a chance for my phone
Any ideas?
up
Can I flash any other firmware like C636B170 or any which is posiible to download? Please help, because I don't know if I can use my bricked Mate as a hammer or still trying to bring him back to life.

Anyone? Anything?

FirmwareFinder fail. Please help me the cheapest way to recover my phone.

I don't know why. I used erecovery with FirmwareFinder many time and it work all times.
But 1 day before, I unlocked bootloader, flash patched ramdisk.img (Magisk), and then reboot again. But then it meet bootloop, bootloader relocked, FRP lock. But this time, when I use Firmware Finder to recover, it cannot work, erecovery failed when getting package. I checked all step.

My mate 9 is briked in i install the last firmware oreo b369... Firmware finder
Please help me! 41$ for 5 credits FunkeyHuawei is too much for me. Could I buy 1 credit to flash firmware?
Are you still having issues, if so, have you been able to unlock your bootloader and flash a custom recovery? If you have I think I may be able to help you
@shae23: Thanks. If I have been able to unlock bootloader, I don't need to creat this thread. I had to bring it to a service shop (Viet Nam), it cost about 6.5$ US to reflash firmware.
someone know what to do ?!!
I unlocked the bootloader and flashed the recovery, the system booted successfully.
I tried to flash a ROM after that, it showed errors and didn't complete the flashing. since that time the phone has bootloop.
Unlocked bootloader and FRP
fastboot oem get-build-number : MHA-L29 8.0.0.374(C185)
I can access the TWRP recovery and erecovery and bootloader&fastboot
what I have already tried :
1-Fastboot flash ramdisk and kernel .
2-Tried to flash the stock firmware via TWRP.
3-Tried HurUpdater0.3
4- Extract update.app & HOWTA
5-Flash ramdisk and kernel from inside TWRP
Update: I can not access the recovery anymore. its just stuck at stock recovery with EMUI 0%
Tried to flash stock and custom recovery, but no luck
Update 2: I somehow managed to get into recovery. recovery is good now.
BUT still no luck with booting, I feel it's something stupid that I missed
Did you try this way?

Need help to get into EDL mode - PANASONIC ELUGA Z1

Hello. Some months ago I have I have tried to root my phone "Panasonic Eluga Z1". I unlocked the bootloader.
Then I tried to flash twrp recovery. But in fastboot mode I by mistake, entered wrong command: fastboot flash boot twtp.img
instead of fastboot flash recovery twrp.img. [coz= noobliness]
Moreover the twrp was not for my model it was for Panasonic Eluga Ray (like this).
Just after the flashing was successful my phone stop responding to any key, it is dead. no response.
However just when I connect the phone to pc it shows response in device manager, sometimes PreLoader USB VCOM Port (COM5) and sometime MTK USB Port (COM4).
(I have attached a file below for more detail)
I have of course tried flashing stock firmware with sp flash tool, but got no success. Before I did it without removing battery, now I try flashing without battery by sp flash tool. It shows several errors which vary conditionally. Errors be like:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
A more detailed file explaining these conditional errors is atteched here: [see attached detail.txt]
May be because, the bootloader thinks twrp is the actual boot image so the phone starts booting into twrp and the twrp dont know how to handle itself as boot image coz actually is a recovery.
I think going to edl mode is the way left for me. But I cannot guess where can be edl test point in my phone:
Please suggest something
Hi I started this thread today and thankfully today only I solved the issue. Sucessfully entered into edl mode without messing with edl test points.
For those members who are getting any sp flash tool error / hard bricked issue with any of the mediatek phone. I'll suggest trying below thread.
ALL THANKS TO XDA
solved my hardbricked / bootoader curropt issue.

QUALCOMM Crashdump Mode on boot even after using MSM tool

So long story short: I was on Flamingo OS A13, got a crashdump mode all of the sudden, I tried flashing again without success. Then I used MSM tool to go back to OOS 11 and after completing, the device just shows the OnePlus logo, screen gets distorted (see image below) and goes off. I try turning it off and on using all the buttons, and I can access Fastboot mode and Recovery only without any problem. But when I try to boot normally, it crashes on the OP logo again and goes into crashdump mode. I tried every latest MSM tool (OOS9, OOS10, OOS11).
Not sure what else to do.

for some reason I always get the same error after using msm tool.
try to boot to twrp recovery using all in one tool or any other way. then flash OOS 11 on both slots (don't forget to format data).
you should be fine. tell us if you managed to fix it by any way

Thanks for your reply. Unfortunately I can't boot to twrp since MSM locks the bootloader and I can't unlock it unless I boot the device first, which is the problem.

can you use fastboot roms?

No, because bootloader is locked and I can't boot up first.

Did find the solution. I have the same problem even the photo that you shared of the phone its the same with lines coming. The MSM tool does it all but again the phone goes black and i can just access Fastboot

Unfortunately, no. After researching about the issue, I found that it's a hardware problem where the RAM or motherboard needs to be replaced. I ended up buying another OP7Pro and decided to get my hardbricked one fixed sometime later.
