Missed the part of creating the "dload" folder. Might want to include that in your original post.

Anyway thanks for the guide ?
[Honor 8 Guides, News, & Discussion] ThePandaGuy:
My downgrade was a bit different. I simply copied the latest Marshmallow upload into the dload folder on my external SD Card. Held power+vol up+ vol down together and it booted and instantly started to install the update in the dload folder. After that I seemed to be in a boot loop but I figured out that you need to boot into erecovery (power + vol up) and factory format it. Did cache too. Once I did that I was back to Marshmallow.

Forgot the mention that my bootloader was unlocked. Not sure if having it locked would have any influence in my procedure.
[Honor 8 Guides, News, & Discussion] macbuggo:
I'm trying to figure out the rollback process and the huawei instructions were VERY specific that you should put it into internal storage (even has screenshots demonstrating this), as opposed to the sd card. I understand that the SD card process probably works, but I was wondering why the difference between this thread's instructions and the official one.
[Honor 8 Guides, News, & Discussion] :
Because it's most likely due to non SD card people? Try both ways I guess
[Honor 8 Guides, News, & Discussion] :
My bad i missed to write it ?
[Honor 8 Guides, News, & Discussion] user_57439:
Does using internal storage instead of SD card work? I don't have an SD on me right now. If it does, what are the benefits of putting it in the SD card over internal?
[Honor 8 Guides, News, & Discussion] clsA:
a lot of things wipe the internal storage and you loose everything in it

while everything on the ext_sdcard is safe
[Honor 8 Guides, News, & Discussion] beachercakes:
Using internal storage (i.e., placing the UPDATE.APP file into a "dload" folder within the root directory) worked perfectly fine for me. Downgraded from Nougat to MM, via Huawei's rollback method.

Worthy of noting: I was rooted with TWRP, with an unlocked bootloader. BUT, I re-flashed a known-good stock Nougat recovery prior to starting the process.

Maybe I'll do a write-up.

It wasn't difficult, per se, but it definitely requires a person who knows what they're looking for (i.e., somewhat technologically literate). If you can't comprehend that last sentence, you're better off saving yourself some peace of mind and leaving the poor (beautiful) device alone!
[Honor 8 Guides, News, & Discussion] Sicardus503:
Okay, so...

I'm in the process of downgrading my FRD-L04 from the EMUI 5.0 / Android 7.0 Beta right now.

I have followed every suggestion so far that is listed here on this post, as well as others listed elsewhere.

Needless to say, while most of the information is correct, the process is not.

Let me explain;

This is for the FRD-L04 version.

(This is my first post so I can't post links just yet, but when copying the URLs below, remove the space between www and .hihonor in the address for the link.)

This link here is the official rollback package;

www .hihonor.com/us/support/details?DOC_ID=92098

This link here is the official Android 6.0 / EMUI 4.1 C567B122 Firmware package;

www .hihonor.com/us/support/details?DOC_ID=89264

Part 1.

1. Download the rollback package and extract the .rar archive provided. Inside, you will find a "dload."

2. Copy the "dload" folder onto the root of your external SD card.

3. Open your phone and dial *#*#2846579#*#* to open your ProjectMenu on the device.

4. Tap "Software Upgrade" followed by "SDCard Upgrade," accept the prompt.

Once that is complete, verify that the process has succeeded by going into Settings > About Phone.

If your Build Number is L04C900B300, you're on the right track and should proceed to Part 2.

Part 2.

1. Download the Android 6.0 / EMUI 4.1 firmware package and extract the .zip. Inside, you will find another "dload" folder.

2. Copy the new "dload" folder onto the root of your external SD card.

3. Open your phone and dial *#*#2846579#*#* to open your ProjectMenu on the device.

4. Tap "Software Upgrade" followed by "SDCard Upgrade," accept the prompt.

You're done.

[Honor 8 Guides, News, & Discussion] Deadbolt:
I'm thinking of upgrading to B385 FRD-L04. Will this method work to downgrade from B385? I tried B360 and had to downgrade back to MM. The battery life was terrible.

Hey guys,

I recently got my Xiaomi Redmi 4 Pro (please pay attention that it is not the Note model).

Is anyone planning to develop and ROMs for this phone or is it still a bit too new for that? I would absolutely love if there was a stable version of CM for this to be honest. It has awesome hardware and the only downside is the software to be honest. Im currently running the stock Chinese ROM and its not that good.

Thank you for the answers
[General Topics] matrixzone:
Congrats on the device.

Can you please confirm if this phone comes with Compass sensor. You can download any sensor app to check
[General Topics] VulcanX:
Yeah from what I can see in CPUZ it does (magnometer its called in the app).
[General Topics] krasCGQ:
Congratulations,

Hope you enjoy your phone.

Unless the kernel source code is released by Xiaomi, no one could develop it.

[General Topics] angelgf90:
The redmi 3s had a cyanogemod rom in very short period of time, so it should be preparing another one for this device, shouldn't it?

Fast charge from 18 % to 71 % in 1 hour.

Battery lifetime more than 1 day.

Fingerprint not working

LED not working

Blue-tooth with problems, car-kit, music player and No1 D5 smart-watch connected at the same time, works a while and than shortly falls away.(Phone was on charger)

When not on charger connect to smart-watch and loses connection much faster, strange??

Have root with Magisk an phh-superuser.

Wifi better than previously 6.0 and Eragon.

4g working.

Some app's not working but can be because of Nougat (Sygic)

4. Flash latest TWRP with SP Flashtool.

5. Flash Magisk with TWRP.

7. Install Magisk Manager from Play Store.

Pseudo news:

There is a small retailer in my country that's selling rebadged P9000s. They're calling it "Keiphone K10 Helio", and I talked with them and said that the Nougat upgrade would be live by the second half of January (didn't say which year ; ) but I'll take that with a grain of salt. They used to sell rebadged Ulefone units, too.

The good news for me is that now I have a local supplier of screen protectors and cases without having to wait more than one month for delivery :p

Even the company logo is Elephone-like... it was really shocking when I found out about this company and saw the same phone, the same promotional photos (but some of them with photoshopped spanish homescreens with a very american looking eagle as wallpaper), almost the same layout as Elephone's website, and exactly the same accessories (sans the Elephone logo, of course)

My Elephone PE+ charger arrived 10 minutes ago. I think is working properly, as my phone is reporting 30 minutes left for a full charge from 50%... and is a little hotter than usual ( top half of the phone, front and back ).

Tried Engineering Settings but I think voltage is no longer reported there ( I can't find the Power section ).

So, in the paper, maybe that 70 minutes full charge is not so untrue after all...
