[Honor 9  Guides, News, & Discussion] waterboy1602:
First of all sorry for my poor English. If you see any language errors, you may always tell them.

After a long road trying to fix my Honor after a bricked it with flashing wrong files with fastboot, I finally fixed it. Because it was so hard to find the right manual, I will write my method down.

This will work for any kind of brick. By example: black screen or reboot cycle. It will also work when you were on EMUI 9 or on a version with a security patch later then June.

Requisites

Access to the inside of your phone

DC-Phoenix + HCU license

ChimeraTool License

TWRP Files for your phone. I used this one.

Huawei Update Extractor

HUAWEI USB COM 1.0 driver installed

You can only install this driver with driver signature enforcement disabled. For this is Google your best friend.​

Firmware files

You can find those on androidhost.ru. Be sure you download the right files. You need two files: one with a security patch later then June 2018, but with EMUI 8 and also a firmware that was released just before June. Unzip already the files you downloaded.

I used the versions B378C432 and B366C432 for the Honor 9 (STF-L09).​

Fixing your phone

Go into test point mode. See the attached picture. You need to ground this point with some metal plate of the phone. For this you can use a paperclip. You need to press the power button while grounding the test point. You can see in Device Manager if you succeeded when you see HUAWEI USB COM 1.0

Start DC-Phoenix and go into the 'update OEMINFO' tab. There you need to select the right bootloader. For me it was the selected on in the picture. You can try as much if you want. This won't harm your phone. Unlock FRP and Update OEMINFO don't need to be checked. Press update and when you get the message with completed you can go to the next step.

Close DC-Phoenix and open ChimeraTool. Cholera will see your phone, if everything went right. Now you need to go to the update firmware tab. Select there the update.app and update_xxx_hw_xxxx.app files from the firmware with the security patch later then June. Otherwise there will be errors while flashing the xloader partition. Now flash these.

Normally your phone reboots automatically. Check in the settings/about if you still have your IMEI. If its not 0000000000 your lucky, otherwise go to the next step.

Shutdown your phone and go into fastboot. You have to extract: kernel, system, vendor and ramdisk from update.app from the firmware with a security patch before June. Flash those files with fastboot:

fastboot flash kernel kernel.img

It's possible that you get an error while flashing vendor. We fix this later.

Try rebooting.

fastboot reboot

If it doesn’t boot, go back into fastboot. Flash TWRP:

fastboot flash recovery_ramdisk twrp.img

.

Go into TWRP by holding volume-up and power. Be sure your phone isn't charging, otherwise it will boot into erecovery. In TWRP you need to flash NVME.zip (you need to flash it 4 times, it's a security precaution). After flashing NVME.zip it should be possible to fastboot flash vendor and reboot correctly.

Check your security patch in settings/about. If it's lower then June, then you've done everything right. Before you use HCU, you need to flash the right recovery_ramdisk (recovery_ramdis) again. Extract it from update.app and flash it with fastboot. Reboot again and let now the magic begin with HCU.

Check in settings/about if you can see your IMEI. If so, then you can use Hisuite to go back to an official firmware.
