[Huawei P9 Questions & Answers] gelgel88:
in the last few weeks, my Huawei p9 had many problems cuz of the last update!

my battery drain was increased, also the mobile shutting down when I used the camera even if battery more than 30%.

i thought all of those problems cuz of update not the battery, when I searched many times I found many guys written the same problems!

i contacted Huawei customer services, they told me that Huawei removed all software from their sites cuz of wrong use from some customers :D

here are how to Rollback your device without any problems.

1) First, download Android Nougat Rollback Package for Huawei P9 from here

middle east http://download-c.huawei.com/download/downloadCenter?downloadId=91646&version=357962&siteCode=kwen

europe http://download-c.huawei.com/download/downloadCenter?downloadId=91727&version=358124&siteCode=nl

2) Now create a folder dload in the root of your SD card and place the update.app file in that folder.

3)Now turn off your device.

4) Now press “Volume Up + Volume Down and Power Button” together. The update process will start automatically.

5) Now wait for some time to complete the process. Your firmware version should now be on “B300”.

6) Now download the full Marshmallow firmware from here

middle east http://huawei-firmware.com/rom/huawei-p9/eva-l19/324

or you can choose your eligible software from here

http://huawei-firmware.com/phone-list/huawei-p9

7) Now move the update.app file in SD card folder (Replace the rollback update.app file).

8) Now again press “Volume Up + Volume Down and Power Button” together to Downgrade Huawei P9 from Android Nougat to Android Marshmallow

9) Done.

This is the complete guide to Downgrade Huawei P9 from Android Nougat to Marshmallow. If you have any questions comment below.
[Huawei P9 Questions & Answers] White18:
This will be helpful. I have some question.

1. In number 2 do you mean to unzip the files and put the dload folder to sd card and leave update.app untouched?

2. And can you elaborate number 7 please? Is it the same update.app in number 2 and do I need to replace it to the downgrade firmware?

3. And is it okay to downgrade when my phone is currently network locked? Will it affect my phone or should i have it unlocked first? Btw my bootloader is still locked and I have no root.
[Huawei P9 Questions & Answers] hamdaan:
I love you man! I nearly gave up! Thank you SO MUCH!

PS- Can we update the phone after rolling back? Or Will the OTA updates brick my phone?
[Huawei P9 Questions & Answers] adtempura:
It works indeed

Many thanks. It works perfect. Il had to use Hisuite to move the file in dload.

Now I get a notification asking me to update to emui 5. Ik don't want to do so of course but I can't stop the notification. Has somebody an idea ?

Hello,

If I do the downgrade, will I lose my pics on my phone ?

Thanks for you feedback.

Reset Netwrok Settings

I was having the same issue ( sudden power-off when using camera or apps that use location), as well as the battery draining very fast.

I followed the steps suggested by Huawei to reset the network and (so far) it apperas to have resolved the issue. TBH its only been two days, but so far its looking good and did not require me to rollback or perform any other intervention. I'm too new to the forum to post a hotlink so you'll have to cut and paste it.

I have no idea, how do I check?
[Huawei Mate 20 X Questions & Answers] lawtq:
Your one is branded to a carrier from what I remember a Chinese seller telling me once. Its the exact same as the AL version which is unbranded to a carrier.

Does your phone have any logos on it which look like they could be from a carrier?
[Huawei Mate 20 X Questions & Answers] hattrickho:
Ohh I see. It has no any special logo on the phone body ,just Huawei. But when I start up the phone. It has a 4G LTE logo loaded up before Huawei logo. Mine shows 4Glte on the status bar. I am not sure does the Al00 shows the same or just 4g.

Ineed help with this message "attackers on <b>%1$s</b> might atte..."

Hi Guys

i have a note5 running android 6.0.1

two days ago i saw the download sign at the top of the screen while i was using the face book app i checked whats downloading i saw this message with a progress bar beneath it like any regular download

The message was

"attackers on <b>%1$s</b> might atte..."

I stoped my wifi connection immediately and it was gone but when i started my wifi agin it restarted then disappeared i couldn't find any info about this on the internet so i did a factory reset just incase and after the reset i updated my apps and resigned into facebook after 5-10 minutes after i signedin that same thing happened again

I hope someone might know whats happening here
[Android Q&A, Help & Troubleshooting] milkyway3:
%1$s is a code used in php language

[Android Q&A, Help & Troubleshooting] DarkCloudF:
Thank you for your help milkyways3

after your answer i read some information about this php code and after some further searching and asking about the issue i found that it might be some adware in facebook but i'm not sure about that i shall search more about this topic

Thanks again

Best regards

[Android Q&A, Help & Troubleshooting] SeaMonster26:
Thank God I found this thread! This same thing happened to me the night of the 17th, but the message appeared and disappeared so quickly for me to see that I only caught a vague glimpse of the word "attacker $..." and could not be sure. I still tried searching online and posting in a forum but came up with nothing. And the weirdest thing is even though this is a download, it does not appear in the downloads folder! I haven't reset my phone yet, as I thought I might have been wrong somehow and it was the regular Instant Apps download or something. I had the premium version of ESET active on my phone at the time, monitoring all downloads and apps and this one didn't even appear there. None of the other scanners I later downloaded found anything either.

At least now I know I'm not going crazy and this indeed happened. I wonder if this had anything to do with the recent Facebook security breaches and server outages.

I am going to reset my phone too, just in case, take some backups tonight and reset. But [MENTION=9568008]DarkCloudF[/MENTION] you said the problem reappeared even after reset? Maybe it installed itself into the system so a factory reset did not remove it? If that is the case, then we got a whole new thing.

Please keep me updated here with your findings, I'm still using the phone as it is, I don't know how to go about this, if reset did not solve the problem, I will admit I'm not very tech savvy and this worries me to no end maybe I should just turn the phone off until I know more and reset.
[Android Q&A, Help & Troubleshooting] DarkCloudF:
Dear SeaMonster26

I did a reset and after i installed the facebook app the same thing happened again then i reinstalled the official firmware for my device using odin then updated all the apps but not facebook and kept monitoring my device for two or more hours and nothing happened then i updated facebook and waited more also nothing happened but after i signed into facebook using the facebookapp it happened again i sent a message to the facebook support but they didn't reply

The last thing i did was that i updated my device to the latest version of the official firmware (for me it's android 7.0) and updated the facebookapp then from the settings->apps->show system apps i disabled the facebook app manager and the facebook app installer

Then i signed into facebook using the app that was 2 days ago and untill now i didn't see that message again i'm not sure if the problem is gone this way but i think the manager or the installer are responsible for this

You can try disabling those two apps as i did after you reset your device and check if it reappears

I'm still trying to figure this out i hope this would help you

Best regards

with this pie update (I updated by Xperia Companion) I got problems with the volume up button. In most cases, I can't increase the volume because the button doesn't activate the panel. With Android 8, all worked like a charm..

That's a pie thing, Google removed WPS support but plans to add it back in a future release (either 9.1 or 10): https://issuetracker.google.com/issues/79404939#comment10

Although WPS should stay removed as it's pretty unsecure.

-Xperia backup not working properly, doesn't backup to SD, stays at 0% and can't connect to online ac****. Google's backup works though.

-The navbar, the style is inconsistent, it should always be like it is in Album app, almost transparent, it looks very nice there. But sometimes its white, sometimes black.

I did flash the FW with flashtool and the 47.2 fsc a user provided here, because the newflasher method didn't seem to fully wipe and format my phone, all the app permissions stayed the same and some system settings, even before restoring the backup. And some tests in Service menu didn't work properly, they're fine now.

Falshtool automatically can download and flash the entire firmware with no modification.

And Next step once switched on - u can redo the RESET option in phone OR REPAIR option of Xperia COmpanion to make sure everything is installed and erased perfectly. Works.

Backup I havent tried, as I have all files stored on SD card or cloud.

Bluetooth no issues at all - I am on UK .33 ROM.

It connects in my CAR and to my Audio system all the time automatically and plays songs and calls uninterrupted. It also connects auto to my GPS.

In Oreo I had a problem with Bluetooth - on apple music whenever I hit play while connected to home audio system play used to stop immediately. I had to change the BIT rate in Developer menu. With Pie - no more of any issue. works all the time with no changes.

I see lags in many apps ... not all when scrolling down or up... (when it slows down it starts this laggy stopping off scrolling)

For example chrome ... it seems like the CPU "runs" back ... or loads the page ... but not ... everything is loaded ... (after flawless oreo is this a disappointment.... )

Something like this happened on previous sony z3c ... and in one of the other updates was this repaired but ... i am afraid ... that this was the last big update ... (oreo had i think only security patches ... after many updates i did not see some significant changes...)

Sony isn't only update the security patches. I remember early Oreo day was a nightmare for my XZ Premium. All bugs were fixed (except the Wifi bug which seems to be Oreo 8.0 problem) and my Phone run flawlessly only after May 2018 patches.

one more issue i have, sometimes it starts to lag like crazy, it happened to me at least twice at 00:00 while having active game profile, the game i was playing became totally unplayable. tried to restart - the same, everything was running very sluggish, tried to reboot in safe mode - was working ok, and when i restarted in normal mode - again very very laggy. no idea what is happening with the device, i think i must return to oreo, really hate this new update :(

On Pie the Akku works (in depend of lightweight or heavier use) between 1 and 3 days on my side.

3 Days with 2h Display use.

But the most of power need Wear OS (16%) over the time.

Maybe it's make a big different, if you have enabled in the statusbar "reduce Data". Mobile Data and WLAN is on all time.

I would stay with oreo but .... the upgrade would to me say everyday ... upgrade ... upgrade so .... (root is for me not the right way... i want warranty)
