[Huawei Mate 10  Questions & Answers] Chito307:
Hi, I have a Huawei Mate 10 pro BLA-L29 C432 with unlocked bootloader frp unlocked that is hard bricked.

Reason why it was hard bricked was using HWota and flashing the wrong files

The device shows up in device manager as USB COM 1.0 (COM4) along with COMMUNICATIONS PORT (COM 1).

I have purchased the DC Phoneix + HCU timed license for 3 days ending on 3/4/2019 at 9 AM.

I have downloaded the "BLA-AL00B_1.0.0.35_Board_Software_China_Nonspecific_An droid_8.0.0_EMUI_8.0.0_05022FPT.dgtks" board firmware directly from DC Phoenix

I have also downloaded the "BLA-L29C_8.0.0.115(C432)_Firmware_Lithuania_Latvia_Norway_Romania_Hungary_Greece_Austria_Czech_Republic_Bulgaria_Poland_Slovenia_Croatia_Serbia_Nonspecific.app" appfile directly from DC Phoenix

I begin by selecting the "BLA-AL00B_1.0.0.35_Board_Software_China_Nonspecific_An droid_8.0.0_EMUI_8.0.0_05022FPT" file in the update file selection. Then i select the "BLA-L29C_8.0.0.115(C432)_Firmware_Lithuania_Latvia_Norway_Romania_Hungary_Greece_Austria_Czech_Republic_Bulgaria_Poland_Slovenia_Croatia_Serbia_Nonspecific.app" file in the update app file selection.

I click update and am provided with the following error message to the left of the screen

File to update: BLA-AL00B_1.0.0.35_Board_Software_China_Nonspecific_An droid_8.0.0_EMUI_8.0.0_05022FPT.dgtks

I then proceeded to try the "use bootloader" option under the udpate oeminfo tab and chosen the Kiring970_T2_A8.0_V3

and i have successfully gotten my device to be recognized as follows

When writing the board file, I get the following

when writing the update.app file directly from dc-phoenix i get the following error

i then though, okay let me try another more rescent .app file, so i downloaded the 8.0.0.158 BLA-L29 c432 "update.zip" file from the internet. I extracted the "UPDATE.APP" file and then selected it in DC-Phoneix and now i get the following message

Attention, this is OTA type file and can't be written via software. Writing it via fastboot may damage the phone. Please use files from our support area.

so I select no, because of this error. I chose to download more "update.zip" files from the internet, and they all give me this attention message.

i then proceeded to use huawei extractor tool to extract kernel,ramdisk,recovery_ramdisk, recovery_vbmeta, and recovery_vendor. I flashed them through fastboot successfully, but no life from the device. As a matter of fact, when i disconnect the device, I have to start from scratch again.

I am really running out of ideas here. =(
