If you have upgrade your bootloader and modem then you can not down grade to 8.

You can downgrade only by flashing custom oreo rom in twrp, there is no other way.

[ROM] Stock BTV-DL09C100B009 European

Hi all,
just found, finally, the stock in the Huawei support site:
http://consumer.huawei.com/it/support/search/index.htm?keywords=btv-dl09&t=SupportSearch
Here you find the ROM and a document with an update to do the downgrade from Android 7.0!
At moment I'm not able to make a upload of the ROM but tryed to install after having messed a lot with other ROMs and the update proc worked flawlessy!
Edit: After the installation the (previously unlocked) bootloader was locked, like new

If you have to ask this many questions, you probably shouldn't be rooting / unlocking in the first place...
Did anybody successfully update from BTV-DL09C100B009 to BTV-DL09C100B303? No problem?
Will be OTA still working when new FW will be released over OTA?
App Firmware Finder shows 3 update zip-files for my M3 to download. Do I have to flash with TWRP all 3 zips to unroot and update?

Global ROM
Hey guys, I'm a complete noob when it comes to rooting my phone and stuff. I was wondering if anyone could help me out. I wish to purchase a M3 from China and was wondering how I could go about to install Global ROM so that I may be able to access Google services and set the default language in english. Will the above link help? Kudos to anyone that could give me a step by step guide.
MANY THANKS FOR HELPING OUT! CHEERS!

Both you are posting in the wrong place.
This a thread on the stock ROM
is also the subforum on "guides, news, discussions"
finally is the subforum for the Mediapad M3, unlikely for other variants.
First read the Forum rules then read it once more!

Downgrade..

Hello everyone
My phone is Moto x4 reteu 1900-7
& Am on pie softWare
So as many here i hve problem in sound (low sound)
So i wanna downgrade to nougat or Oreo..
So wat i ask for is were i can download The software for reteu 1900-7 (nougat or Oreo)??
This phone wasn't launched with lollipop, marshmallow, nougat so there is no such firmware for it. As for oreo, you can find all official firmware here.

Hi

And this topic does not work
https://forum.xda-developers.com/rog-phone-2/how-to/how-to-unlock-rog2-phone-via-edl-mode-t4008267
Please help me
The tool didn't work on the beta either. I had to flash Android 9, unlock bootloader with the tool, and then update to Android 10.

Yes, I just flashed the RAW Android 9 file. I have WW version.
https://forum.xda-developers.com/rog-phone-2/how-to/1910-64-ww-update-t4021947
but this is so dumb... why don't they already have it updated. they knew the release was here.
Beta 9 was already the "full" stable update.
ugh. now i need to go back, unlock and then go to android 10.

you can also use the asus downgrader: https://www.asus.com/Phone/ROG-Phone-II/HelpDesk_BIOS/ and download Version Android 10 downgrade to P (WW) - Or use the one catered towards CN version if you have that.

If you find a 9.0 firmware in xperifirm, you can flash it with newflasher.
Both have XDA threads.
Already downgrade
