Help with rooting nougat mate 8 + Question - Mate 8 Q&A, Help & Troubleshooting

Warning: This is probably gonna be a long post and may have typos.
Now, let's cut to the chase.
I'm currently on my Mate 8 emui.4, I had my phone rooted a while ago with TWRP and SuperSu. After rooting, I had the nougat update and I updated without knowing that it would remove TWRP and my root access. That was not the only problem! I couldn't switch on my Bluetooth. Also I lost the update option from the about phone location. I tried searching it in the search bar and clicking on the update button but, nothing would open up. And.. Yes, it was an official update. I tried to root it with the usual method but, it got me into a bootloop. I tried most TWRP versions but, it didn't seem to work! Either there would be no recovery (just a Black screen with some text) or the options inside the TWRP recovery wouldn't work. So I rerolled back to Mate 8 marshmellow. Now I don't have root, no TWRP or unlocked bootloader. So my question is if I should root my current phone version of emui.4 and be satisfied by it by unlocking bootloader now and rooting it, or update my phone to Mate 8 nougat again? If you're suggesting I update to nougat please provide me with ALL the necessary files and please guide me through. And provide be with the information on what to do in the worst case scenario too.. Please . :crying:

Anyone?

How to FRP Unlock my Honor 8?

hi
I have a Honor 8 FRD-L09C432B394, rooted latest magisk and twrp.
There is an OTA update, available, on the phone only, not available with HiSuite..
I would like to update, I uninstalled Magisk, But no way to replace twrp with stock recovery with latest Huawey MultiTool V8.
Don't know why but my FRP is locked.
I found some ways to solve it, AAbox2_17.11, or DC Unlocker 2, but I dont understand how it works, and I don't want to brick my phone...
I also found a tutorial to downgrade from Nougat to Marshmallow, this could solved my problem...
Do you have any info? Please.
thanks for your answer, I will try it with huawey tools
Ok, I finally managed to update my firmware to b399...

Soft brick? Boot-loop after trying to update wrong firmware

Hello.
I've read through the forums but am still quite unsure if i can restore my honor 6x from soft brick. It boots up but i get stuck in rescue mode if i have it charged Or it will just boot-loop if its not plugged in.
Im unable to use the DLOAD method. If i enter fastboot and use the three button method. I get put to the rescue screen. However i may be using the wrong firnware? Possibly.
Its a China version. PE-UL00 given to me from a friend, he said he had restored it to factory settings. So i wanted to upgrade the android kit kat to lollipop version. It was running emui 3. Kitkat 4.42. I believe updated the wrong firmware file through the local update method I download from firmware finder.
Basically from what ive read through the forums would i need to unlock the bootloader and flash stock firmware? . I have the information to acquire the bootloader key i believe and. I have downloaded honor multi tool and huawei multi tool, as well as adb drivers
I get confused as to which stock rom or. Firmware i should download or use. And i cant access the phone to see the build number. All i know is that it's. A China version. PINE-UL00. HONOR 6X. I do remember seeing
UL00_V100R001CHNC00B200 or similar when i was able to access the phone. But it also had custom at the bottom so i wasn't sure if it was a custom rom.
Any suggestions for a noob. Thankyou.

I downloaded dc unlocker, but it doesn't support the boot loader id for PE-UL00 honor 6x. Im still waiting on huawei for the bootloader code. I think k have to log in for 14 days consecutively? I keep getting that message when I try to unlock.
Also the firmware I tried to update it was PE-UL00C00361 OTA-MF from firmware finder.
I downloaded dc phoenix unlocker. Found the correct stock firmware to the best of my knowledge and the phone back to normal. After I was able to update to marshmallow through system updates.
Thank you anyway

How to root Honor 6X BLN-L21?

Guys i want to root my device - Honor 6X BLN-L21. how can i do this?
after rooting my device ill be able to update my software ? i have the latest android 7 official update from huawei installed. i havent unlock the bootloader or anything like that.
thank you and soory for my english.
Follow this guide https://forum.xda-developers.com/honor-6x/how-to/root-huawei-honor-6x-install-twrp-t3671822
And for obtain your bootloader unlock code, note that the listed procedure is impossible to follow at the moment, because the necessary pages to ask for the code are unavailable on Huawei sites. But you should be able to have a work around thanks to the module available here https://forum.xda-developers.com/ho...cial-request-bootloader-unlock-codes-t3785100
I am resurrecting this thread as I have the **same** issue a year after.
I have recently aquired a BLN-L21 Honor 6x europe, with EMUI 5.0.3
This is the exact ROM version: BLN-L21C432B382
It has been rooted using dc-unlocker, but now I have some problems with rooting (that was my entire objective since start)
Compatible TWRP are scarce, I can only make it work with OpenKirin TWRP 3.1.1.0, linked in the guide above, or EliteTWRP-3.2.1.0, but this one cannot read any internal partitions, so I guess it's not very useful.
As soon as I flash Magisk-19.3.zip the device boots and asks me for a decryption password, that I clearly don't have.
So Flashing Magisk this way makes the terminal useless.
Can anyone suggest me a couple of TWRP + ROM that supports root quite well on this device?
EDIT: ouch, I defeated myself. I just tried to use SuperSU-v.2.82-201705271822 and it works like a charm on stock rom.
I wonder why Magisk makes a mess of the partition

Honor 8 sort of half rooted?

Hello, first of all i want to say that i don't understand a lot of those thing, i'll just try to explain myself as best as i can but if you don't understand something just ask and i'll rephrase it somehow.
I have an EU FRD-L09. When i bought it i tried to root it because i couldnt mute the sound of the whatsapp camera. I did some things (it was a long time ago, i don't remember precisely what) and the phone was in a state where superSU told me that there was no root, but at the boot i always got the message "your device has been unlocked and can't be trusted etc.. ". I was tired so i left it like this until now, the only thing that mattered is that i could use the phone. Now, i want to update from FRD-L09C432B380 to FRD-L09C432B389 (and then hopefully to android 8) but i just can't. When i try to update it, either from the phone or from hisuite it reboots and get stuck in the "your device has been unlocked" state with "your device is booting now..." forever. The only thing i can do is to go in erecovery and reboot. I also tried to restore from erecovery but it says that "Getting package info failed". Restoring from the settings does the same as trying to update. Somebody know what can i do?
I Don't think you ever rooted the phone. From what you said, you only unlocked the bootloader (phone cannot be trusted message on boot). Have you tried dload method to get the system to stock and then updating through HiSuite? (AFAIK This will wipe system and data)
I read about it and i will try it. Should i flash the rollback package from android 7.0 to 6.0 or directly the 6.0 firmware? Right now i am on emui 5.0 android 7.0.
P.S. so i can't update the phone in any way with the bootloader unlocked?
