Mate 9 Bricked

[leandro9000]

Hello, I have a huawei mate 9 and I tried to downgrade android version, but I used the wrong file which caused a hard brick on the device ... I cant acess the recovery or bootloader mode... it does not turn on and don't gives any sign of life... it is possible to recover in this case? thanks!

Doubtful. Maybe using testpoint, method 3 from dc-phoenix.

Hey. I've made a similar mistake and hard-bricked my US mate 9. I'm interested in trying out the DC-Phoenix Method 3, however the download links for the firmware does not seem to work anymore. Is there somewhere else I can find the required firmware?

[Valdemaras]

All firmwares on support area accessed only from dc-phoenix.

Thanks for the quick reply. Those are the files I'm referring to. When I open DC-Phoenix, choose "Download Files", input "MHA-L29B C567" in search field and click the two links that appears, I get "File not found" on both of them. I tried some of the other MHA-L29B firmware builds and I get the same problem. Do I have to input a password somewhere, or something similar, for the files to become accessible?

[Valdemaras]

Please send screenshot with the error/problem that you get on your browser, you log in on software launch that is enough.

It seems the problem has resolved itself. I am able to download the files now. Sorry for your trouble. I'll try method 3 out at once.

I'm having a little trouble with method 3. I've managed to flash the board software on my phone and restore the phone data with HCU. However when I go on to flash the US firmware build unto my phone it hard bricks again. What am I missing? Has it something to do with the firmware I am flashing (MHA-L29B C567B190)?

EDIT: Okay I realize that the above file is OTA and will not work. I've tried yet again flashing board factory firmware -> update phone data in HCU but now with eu instead of us as country -> flash eu firmware from download section in DC-Phoenix. However a couple of seconds after flashing i get this:

Erasing ver .. .
Writing rescue_recovery_kernel partition
RESCUE_RECOVERY_KERNEL partition update ...OK

Hey thanks for trying to help me out. I'm not gonna put more time into resurrecting the phone. The software worked well and it was fun trying to figure out how it all worked.
