[Honor 8 Questions & Answers] kayro_:
Hey guys,

I'm not far from just buying a new phone - so, this is my last try to get my phone running again with your help.

Two days ago I tried rooting my phone (Honor 8 FRD-L09 - OS: Android 7.0 Nougat) and it miserably failed.

I'm pretty depressed at the moment, so please don't mind if I list every small detail I did, in hope that someone can help me:

Installed Minimal ADB and fastboot on my Windows 10 machine: Version 1.4 - 17.10.2016.

I plugged in my phone and started the fastboot mode (Vol-Down + Power).

Now I got my code for unlocking the bootloader from Huawei, started a PowerShell and executed: "fastboot oem unlock ****************".

The unlock was successful and after rebooting the fastboot mode screen said: "Phone UNLOCKED".

Downloaded TWRP (twrp-3.0.2-0-frd.img) and placed the .img file inside the adb folder on my machine.

Back into PowerShell I typed "fastboot flash recovery twrp-3.0.2-0-frd.img" and "fastboot reboot".

After rebooting I pressed Vol-Up + Power to boot into TWRP.

In TWRP I recocnized that my Internal Storage AND my SD Card were list under storage both with 0MB.

Anyway I went along: Downloaded and placed SuperSU-v2.82-201705271822.zip with "adb push SuperSU-v2.82-201705271822.zip /sdcard" to my phone.

When I tried to install the SuperSU-v2.82-201705271822.zip in TWRP over the Install Button there was an Error in the log console: "Unable to Mount /data".

I've googled the issue and stumbled over a thread in a random forum I can't remember - anyway, some user said I have to format the partition because /data is in some kind encryption mode.

I opened the ADB shell in TWRP and entered a command that user mentioned to format the partition - after that things got ****ed up!

Now when boot my phone I get an test screen: two rectangles in blue and red and an green background.

After the testscreen there comes the message "Your device has been unlocked and cant be trusted. Press: Power to continue, Power-Up to enter erecovery".

When I press Power-Up the EMUI logo appears and I can start "Download lastest version and recovery" -> This fails with the message "Getting package info failed".

So, I downloaded the "Honor 8_Firmware_FRD-L09_Android 6.0_EMUI 4.1_C432B131_Western Europe.zip" extracted the dload folder witth the UPDATE.APP to my sd card.

I rebooted the phone, pressed Vol-Up + Vol-Down + Power to execute the firmware -> The install process is sarting but fails at 5% with "System installation failed.".

I installed HuaweiUpdateExtractor and extracted the boot-, recovery-, cust-, system.img placed these files inside the adb folder and executed the following commands:

fastboot flash recovery recovery.img -> SUCCESS!

fastboot flash boot boot.img -> FAILED (remote: Command not allowed).

fastboot flash system system.img -> FAILED (remote: Command not allowed).

fastboot flash cust cust.img -> FAILED (remote: Command not allowed).

After rebooting my phone got stuck at the normal boot screen mentioned in point 14.

The extraction and fastboot flash process I repeated with the rollback package: Honor 8_Rollback Package_FRD-L09_from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1_C900B300_German.zip.

With exact the same result.

I also tried this with the Nougat 7.0 UPDATE.APP -> same result as mentioned.

Status quo:

Got odd test screen (red, green, blue) right after starting the phone.

My phone can only boot to the fastboot mode.

eRecovery fails with "Getting package info failed.".

Flashing from SDCARD fails at 5% with "System installation failed.".

Tried to install TWRP again -> no chance, got stuck at the screen mentioned in point 14.

I appreciate EVERY help!

Greetings from the depressed Honor 8 rooting hell,
