[Honor 8 Pro  Guides, News, & Discussion] akhilbs94:
Hi,

So many of us are not happy with the oreo rom of Honor 8 Pro (C675). Those who looking forward to downgrade from Oreo to nougat just follow the steps. (This method is tested and is working. I just finished downgrading and is working perfectly fine. I just want to share this method with you guys. Also this i my first post in the forum. Some steps have been copied from a previous post by xfact)

Things you might need :-

>>A computer

>>At least 8GB memory card.

>>An unlocked bootloader. (you can relock it later)

>>Download the necessary files here :- [The Dload file was previously shared in this forum by xfact, but the link is not working now. Fortunately, I downloaded the file while it was available and I am providing the link to the google drive backup.]

REMOVE THE *** IN BETWEEN THE URL'S

(a) Dload File --- https***://***drive.google.com/open?id=1ZpOoPZ3dEn86lEh0PwlZP0W2LShM-BnT

(b) Recovery File --- https***://***drive.google.com/file/d/1qiP4k5HtJ3VR5l9ac8FnpxrwryIxu-pV/view?usp=sharing

(c) ADB platform tools --- https***://***drive.google.com/open?id=1vu-awRNjH3B9os5MuHGSlu-ca6zNv10V

>>Unzip the above-mentioned Dload file, then go to the folder, then software>dload folder and unzip the 'SDupdate_Package.tar.gz' with 7-Zip. It will extract another archived file called 'SDupdate_Package.tar'. Now unzip that too with 7-Zip and you will get a folder called 'dload' again.

>>Now take an SD card with at least 8 Gb of space, format it to exFAT. Paste the last 'dload' folder and all its contents at the root directory of that SD card. Put it into your phone.

>>To unlock the bootloader, just log into---- https***://***bit.ly/2uEEvdj

This is their chinese website, use translator in chrome to read in english.

Fill up the necessary details and you will get an unlock code for your device.

>>Follow the necessary steps to unlock your bootloader from here :- https***://***bit.ly/2uEM1F8

>>After unlocking the bootloader, your phone will be factory reset. When the phone boots up again, go to settings and enable USB Debugging from devoloper options.

>>Unzip the platform tools zip file and copy the Recovery file into that folder.( you have to unzip the platform tools file while unlocking the bootloader. Just copy the recovery image to that folder)

>>Holding the SHIFT key, right click any empty spaces in the folder and from the menu that appears, select "Open command window here"

>>Connect your handset. Ensure USB debugging prompt appeared as seen in the bootloader unlocking tutorial.

>>In the command window type the following commands :-

1. adb devices

(this is to make sure your device is connected properly)

2.adb reboot bootloader

(to put your device into fastboot mode)

3.fastboot flash recovery_ramdisk DUK-RECOVERY_RAMDISK_NoCheck.img

(to flash the recovery image)

4. fastboot reboot

>>When the device boots up, go to the dialer, type *#*#2846579#*#*

->Click on Software Upgrade -> SDcard upgrade->confirm.

Your phone will recognise the memory card with dload file in it. It will flash the rom. It will get stuck at 99% and shows error. Dont worry, just select reboot system option that appears on the screen.

You will be on the Nougat Rom

To relock the bootloader--

>>Again you have to enable USB debugging from devoloper options>>open command window from the platform tools folder>> execute the commands 1 and 2.

Then type the following command :-

fastboot oem relock *unlock key*

(replace *unlock key* with your unlock key used for bootloader unlock)

YOUR DEVICE WILL BE ON NOUGAT ROM WITH LOCKED BOOTLOADER

As this is my first post, kindly ignore the errors. Sorry if this lengthy post made any confusion. Hope this is helpful to all of you.
