Possible to Downgrade from EMUI 4.1 to EMUI 4.0 - Mate 8 Q&A, Help & Troubleshooting

Hi,
my phone is NXT AL-10. It came with B180 ROM. I upgraded to B323 version through dload method.
i tried to unlock the bootloader through dcunlocker. When i unlocked through OEM Unlock method, it gave me some error but i could see the confirmation and other usual stuffs in phone screen. So i proceeded.
Later i installed TWRP for EMUI 4.1 and installed L29-B320 Stock Rooted firmware. Everything went fine. But after this only my problem started, i tried to flash some zip (like fonts) its not working. I tried ES file explorer it says i don't have root permission. So really don't know whats happening.
Now, i really want to go back to L29-B180 Stock rooted for good. Possible? any kind soul can point me a correct direction?
Thank you.

Downgrade MM to LP?

I know there are a lot of threads. I read it's impossible. But another says possible using pda file with pit info, but i can't file proper file for g920i.
Are there any workaround to dowgrade?
I googled everything, but no luck. Stuck on MM.
Mm battery is bad for me.
Can we install custom rom LP while on MM bootloader using twrp? I know that only the bootloader part cannot be downgraded. Have someone created a hacked bootloader or somehow?
Or maybe prefer upgrade to nougat? I'm afraid because i will not be able to get back to MM after that.

There is only one way and that's with an engineering bootloader but this breaks fingerprint other than that it's not possible to downgrade to lollipop even with custom Rom this is down to being on newer marshmallow bootloader.

There is a guide in the general section I think, you might need to search for it. From what I saw last in it, some users got it working but others not so can't really comment on the success rate and plus it's nothing something I've done myself.

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...
thanks @Rommco05
But, now, I have a problem with the bluetooth...
I posted another subjet about that :

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

Nokia 3 8.0 Root - Is there a working method, or NOT?

Hello,
this is the very first time here at XDA Developers Forum that I do not find clear information about rooting a smartphone. I am talking about this Nokia 3 updated with OREO 8.0. Only a lot of confusion reading your posts, sirs. Nobody that is telling if rooting this model is possibile or not. So... can anyone says if it is possibile and how to do that, in a clear and simple manner?
Thanks and regards!

this thread should be on Q&A.
Hello,
thanks for your reply. I already read this thread.
So since I am on OREO, it seems I have firstly to downgrade to Nougat. Can someone please tell me how to do that, posting links to the official 7.0 rom, the software and a short guide? Somewhere I read you have to use OST, somewhere else SP Flash Tool...
Thanks in advance and regards

Hello again...
I am trying to downgrade my Nokia 3 8.0 to Nougat, in order to unlock the bootloader.
I have searched a lot for an official 7.0 rom... nothing official... I tryed to follow this guide:
https://forum.xda-developers.com/nokia-3/development/nokia-3-official-firmware-india-uae-t3674320
Managed to install and get a working copy of OST. Connected and start flashing the rom NE1-147I-ind-0-00WW-B02.nb0 (the one I thought it was the earlier one, since nobody wrote "7, 8, or another number" in the file name). OST got stuck at "Reflash service bootloader..."
Can anyone please write a clear guide on how to proceed to root a Nokia 3 OREO that was never ever unlocked before (i mean with bootload never unlocked)? I am going crazy, really...

flash UAE version of nb0 if IND doesn't flash, that's Android 7.0 May 2017 Security Patch, unlock and lock bootloader there and apply OTA updates from notification up to latest update. Then follow guide.

which ost la version you have?
I finally managed to downgrade to Nougat 7.0.
Now, in order to get root, do I have to unlock bootloader first? Can I obtain the code only via a request to the_laser (that didn't answer me) or can I use an online tool ?

you need to unlock bootloader first, and you can PM code i will send you key, use only OTA through notification, don't use OST LA for this guide.
