[Huawei P8max] Hirs_E_Fruit:
There is a offical Rollback for Android 6.
[Huawei P8max] UzY3L:
Where? Show me, please!
[Huawei P8max] kingkea:
What does it give you?
[Huawei P8max] Hirs_E_Fruit:
About 2-3 Hours more batterylife! ;)
[Huawei P8max] m00h:
Can't confirm that. My battery drained way faster than under Android 5.

Also, where can I find the official rollback?
[Huawei P8max] UzY3L:
Tried every known firmware and tried force firmware update for the rollback. Nothing worked. Android 6 is the end of the road for this phone, because in EMUI 3 you have the "Local update" function in the Update menu. In EMUI 4 (Android 6) that is removed. Service center for rollback first thing in the morning. If not, I'm selling the phone and rolling back by buying a new one with EMUI 3.

So, after 2 days with this horrible software, here's what it "adds" :

-search function in settings

-fast scrolling via side-bar and not by how fast you swipe down or up

-dedicated "Messaging" app removing the "Messaging" function from "Phone"

-removed 50% of the toggles and replaced them with "Edit"

-added a "Light bulb" next to the clock in the Notifications menu but it is not a shortcut for the flashlight, no. It takes you to the Huawei Smart Care app which is for...health

-removed the "Camera" button from the lockscreen. You now have to swype up very carefully in the middle to brink up the mini-menu, then select the Camera

-took a lot of heavily used settings and moved them to the bottom of the menu, in Advanced settings where they don't even work by tapping them. You have to get to Advanced, tap the option you want and then confirm it by a Check in the top-right of the screen. You know, in case you accidentally got there...

-the phone no longer remembers your last storage option. Every time you connect it to the computer it will be "Charging only". Which is retarded, when you consider that the phone knows when it is connected to a computer or to a charger so the only time you connected it to a computer is...to transfer data.

-speaking of data, "Mass Storage" mode for the SD Card has been removed. Enjoy MTP because it has been such a great "success" since its launch, people just love it.

-I'm sure lots more was ****ed up but this was all I could find in such a short time.
[Huawei P8max] UzY3L:
Also to add :

-reversed the call buttons. If green was on the right and red on the left, they are now reversed

-also when receiving a call, you will sometimes get a circle to make a selection of message, hang-up or answer / and sometimes you will get direct button. it is totally random, like Android having a seizure

-notifications can no longer be swyped away to the left or right. You have to swype up.

-when you get more than 1 notification (ex : whatsapp) it just say 2 or more messages. Android 5 displayed messages in the notifications, until it reached the bottom

-battery manager no longer tells you how much time you are on battery. You're given a percentage and a date and you're left to calculate on your own approximately how many hours it has been since the last charge

I swear, it's like they fired the team who did EMUI3 and brought in a new team that randomly mentioned ideas.

You can feel that EMUI4 was designed by someone who has never used a P8 or a P8 Max in their life. Or even used EMUI3 at least.
[Huawei P8max] Hirs_E_Fruit:
Well then you will never use EMUI 5 cause it will change everything you know from the crappy EMUI 3.1.

I am so glad I got EMUI 4 cause most of your things I dont use cause I Root the phone and changed it so much.

I love the 10 hours SoT ;)

[Huawei P8max] m00h:
I get 10 SoT on B029 after cleaning it up.

Also no need for service center to rollback. You need to extract few things from the full b028 fw and then flash while fastboot. There is a howto somewhere here how to do that.
[Huawei P8max] UzY3L:
Please, man. If you can find it, I'd be very grateful. I can't use the phone with EMUI 4

[Huawei P8max] Kurcina123:
This hungarian version is D001 and mine is D002 will there be any problem? Are there any news about android6 for west eu?
[Huawei P8max] kingkea:
How?

---------- Post added at 05:20 AM ---------- Previous post was at 05:17 AM ----------

Hey bud, where did you sell and for how much? I think I'm going to sale mine too.
[Huawei P8max] m00h:
I rooted the phone, removed every unnecessary app with TitaniumBackup, installed AdAway to block ads, managed all permissions for necessary apps (Internet, background running, startup).
[Huawei P8max] kingkea:
Thanks. I love the battery life of this thing. If I can ask you a bit more. What apps did you deem unnecessary? I think I can get about 6-7hrs SOT. I've considered root because I have issues with notifications with some apps (even after I out them in a protected state).

Ads don't seem that intrusive and I use a lot of apps that are supported by ads, so idk about that part.
[Huawei P8max] JebemVamMater:
Huawei Croatia told me they are going to release android 6 sometimes around end of this month. Huawei France and South Africa updates are still in beta and they are working on it.
[Huawei P8max] zaied aliraq:
Update error , mine is CUSTC199D002, any idea ? thanks
[Huawei P8max] mani_manish_2000:
Which region phone you have? My P8 Max has:

Build Number -- DAV-701LV100R001C199B005

Custom Version -- CUSTC199D002

I bought it from Amazon.com in the USA and use it in India.

Which region phone is this? I should wait for Android 6 Update of which region?

I see that there's an official Android 6 update for DAV-701L available in Huawei Support site, but it says its for Cambodia region. - http://consumer.huawei.com/kh/support/downloads/detail/index.htm?id=84050
[Huawei P8max] zaied aliraq:
region is middle east, I have downloaded the firmware from the official website but it can not be installed!

I got an error just after the restart.

DAV-701LV100R001C199B005

CUSTC199D002
[Huawei P8max] mani_manish_2000:
seems its compatibility issue with our CUSTC for the released update as that is for Cambodia region and with different custom version.

We might need to wait for the correct update released for our phones.
[Huawei P8max] kingkea:
Gotta wonder. I have that same cust, do you think it'll ever be released?
[Huawei P8max] poLiSen:
Has anyone else gotten problem ADB client on phone not showing the authorization popup when the ADB server on PC try to communicate? Currently I cannot access my phone via ADB. Bit of a nuisance. Never experienced this problem before on any other phone/tablet after an upgrade.
[Huawei P8max] poLiSen:
In case someone run into the same problem as me (this assumes ADB work while in recovery mode):

Boot into TWRP

Click "Mount"

Check "system"

Go back

Open a terminal and run:

adb pull /default.prop .
adb pull /system/build.prop .

BACKUP BOTH FILES!

Add these lines in the end of both files (also add a empty new line in the end):

#Custom
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb

Save files with UTF-8 encoding

In terminal run commands:

adb push default.prop /default.prop
adb push build.prop /system/build.prop

Depending on OS you run:

Linux

adb push ~/.android/adbkey.pub /data/misc/adb/adb_keys

Windows

adb push "%USERPROFILE%\.android\adbkey.pub" /data/misc/adb/adb_keys

Reboot phone

This do not solve the issue with a non-existing authorization popup but it does authorize the current PC you are using.

You could of course try to do these things via a "terminal emulator" app while having the OS running. Might be a good idea to use a "build.prop editor" app as well.
[Huawei P8max] eastcyber:
Hi all,

P8 Max user from sunny Singapore here. Have just updated the phone to Marshmallow using the link provided in the threadstarter's post.

After 3 days, I must say the usage and feel of the update is very good. Using the phone somehow feels more smooth and it seems battery life got improved as well.

The strange thing though is the prompt I get after updating though. I got a "update failed" message but when I restarted the phone, it shows that the phone is now running EMUI 4 and Marshmallow....

Hope those who had problems not give up on the phone just yet, troubleshoot and try again? For myself, I have experienced no issues with the phone after updating (so far! ????)
[Huawei P8max] kingkea:
Wish I could update. Wrong cust. Wonder if this one has been abandoned with Android 7 being out now.
[Huawei P8max] eastcyber:
My phone CUST is also different but I still went ahead anyway ???? Definitely not a recommended course of action though
[Huawei P8max] christcentric:
I can't make it beyond 5% before the updater bails on me :(

Could any kind soul use the Huawei Update Extractor (http://xdaforums.com/showthread.php?t=2433454) and extract the boot.img and system.img from this update? I only use macs at home and at work, and my wife is on maternity leave so her Windows laptop was left in her office ... thanks in advance! :)
[Huawei P8max] christcentric:
Ok so i got my hands on a Windows PC, used the extractor, flashed boot, recovery, cust and system from the UPDATE.APP ... and now i'm stuck on the Huawei logo. Should I flash other images in the APP package in the hope of making it work, or should i find a way to rollback to an earlier ROM? Or, should I be really patient and see if it moves beyond the Huawei logo?

I read somewhere that the partitions from Lollipop 5.1.1 and Marshmallow 6.0 have changed a bit, so the extractor can't quite handle the img extraction as well as it used to ... guess I was a tad too gung-ho.

:( Pls, some help would be nice!
[Huawei P8max] Hirs_E_Fruit:
What do you want to do?
[Huawei P8max] christcentric:
Primarily, I'd like to get my phone to boot properly; right now it's stuck on the logo. If this means rolling back - I don't mind. I'm not afraid of using some elbow grease: getting down with adb and fastboot, and doing some coding.

My secondary goal is to get my DAV-701L CUSTC199D002 running Marshmallow, if possible.

Thanks in advance! :)
[Huawei P8max] Hirs_E_Fruit:
So first you need the following.

1. Clean DAV-701L firmware.

2. Huawei Firwmare Extractor

3. ADB and Factbook

4. P8max TWRP

After you have all those.

1. Locate your Update.app from your 701 Firmware.

2. Use Huawei Firmware Extractor and extract the follow from your Update.App

boot.img , recovery.img, cust.img , system.img , cache.img , userdata.img

3. after rename all the files you have extracted from Huawei Firmware Extractor ( they should be called. "10.boot.img , 11.recovery.img .... etc") to the following:

"boot.img, reocvery.img , cust.img, system.img, cache.img, userdata.img"

4. So now you need to put those files in the exact place as your ADB and fastboot. So your FOLDER should look like the following:

ADB.exe

Fastboot.exe

"some ADB & FASTBOOT files"

boot.img

recovery.img

cust.img

system.img

cache.img

userdata.img

Also, put the updates.app file into your SD card under the folder "dload". So it should look like "X:\dload\updates.app"

After you have the following setup, do the following on your phone.

Make sure your phone is shutdown.

1a. plug in USB then (vol down + power) to boot into bootloader

** If your phone can not shutdown because you are in a bootloop**

1b. Make sure you have (hiSuite) installed, plug in your USB to your computer. Hold all bottoms till the phone turns off a vibrate. Then hold (vol down + Power) to get into bootloader

2. Use command prompt to go into your setup you have done at the top with ADB, fastboot and img files.

" cd c:\your\folder\here\p8max " for example

type "fastboot devices"

you should see your devices show up. If it doesn't then you have driver problems you have fix first or you don't have hiSuite installed. (Try re-installing hiSuite)

If you see your device show up, type the following

MAKE SURE EACH "fastboot flash" SAYS OK BEFORE DOING THE NEXT STEP.

type "fastboot flash boot boot.img"

type "fastboot flash recovery recovery.img"

type "fastboot flash cust cust.img"

type "fastboot flash system system.img"

type "fastboot flash cache cache.img"

type "fastboot flash userdata userdata.img"

If all are ok, you want to:

type "fastboot reboot"

This should restart your phone. You should be able to boot up your phone. Once you have your phone boot, your not DONE YET!

Turn off your phone, make sure the B029 update is in your SD card. (see example above)

turn back on your phone and hold (vol up + power) with NO USB plugged in. This should force your phone to force update back to 701 Firmware.

Make sure you get to 100%. NOW YOUR PHONE IS FIXED! - it will reboot, then now you should be done

If you get stuck at 90% then you need to clean up your internal storage first.

---------- Post added at 05:18 PM ---------- Previous post was at 05:15 PM ----------

This should work with a full Android 5 Firmware.
[Huawei P8max] christcentric:
Thank you very much! This is a very comprehensive set of instructions. However, I'm not sure what you mean by "clean DAV-701L firmware" ... I am on CUSTC199D002, and my last firmware was B005. Which firmware should I use for rescue, and where can I download it? (Huawei's site shows very few firmwares for download, and club.huawei.com is a bit of a mess. Heh.)

Also, is there any way I can get 6.0 Marshmallow on my device? :)

Thank you again!
[Huawei P8max] Hirs_E_Fruit:
Just Download a full dav 701 Rom, i dont really know where you Can get it since i only have a 703. The Problem is that the international Version doesnt get much Support from hauwei and search for rom is a pain...
[Huawei P8max] christcentric:
Indeed. I was hoping I could flash my way to 6.0 easily. I will try to load an european DAV-701 ROM, and then try to upgrade from there ... thanks!

---------- Post added at 01:16 AM ---------- Previous post was at 12:17 AM ----------

Also, I can get into Huawei eRecovery, but when I select Wifi Restore it says that there's an error starting Wifi ... any way around this?
[Huawei P8max] Hirs_E_Fruit:
Maybe cause the wifi is password protected?
[Huawei P8max] christcentric:
It should allow you to scan and select your networks, no? And I removed password protection from my wifi network and it still didn't work. Not sure how this eRecovery is supposed to work ... can't find much info online about it.
[Huawei P8max] Hirs_E_Fruit:
as far as i know it should simply downoad the os and install it from the internet, but i am not sure if there is a dav 701 rom online on some huawei server

which country are you or you know where your cust (phone) region belong?
[Huawei P8max] christcentric:
I reckon CUSTC199D002 corresponds to Pakistan?

But I don't even think the phone is making any attempt to connect to the Internet in eRecovery at all....

In any case, with the very detailed instructions you've given, can I flash with a full clean DAV-701 rom from either Europe or Thailand? Will this change the CUST/region as well? :)
[Huawei P8max] ellasgr:
Hello also own the CUSTC199D002, wants to know whether it has anyone tried
[Huawei P8max] Hirs_E_Fruit:
i dont think it should be a problem since you flash the cust from the other region too in my instruction
[Huawei P8max] christcentric:
Hey thanks a lot! Your instructions worked. I used them twice over.

I used the B002, and then upgraded to the B005 (both Thailand region ROMs).

However, I there is no entry for CUST info under About Phone, and when I got into ProjectMenu it just says CUST.

And, I still cannot update to Marshmallow, with the UPDATE.APP in my sdcard.

Should I just do another dirty flash with the Marshmallow files, and will this work?

Or is there another way to get Marshmallow on this? Or should I just resign myself to never getting 6.0? :/
[Huawei P8max] Hirs_E_Fruit:
Did you extract the files to your SD card into the dload folder?

Did your try local update?

---------- Post added at 03:30 PM ---------- Previous post was at 03:28 PM ----------

Did you try the force update method? "Hold Vol up + Vol down + Power for a few seconds till it starts to upgrade."

---------- Post added at 03:31 PM ---------- Previous post was at 03:30 PM ----------

The update.app has do be on your SD Card in the folder dload.
[Huawei P8max] christcentric:
Yes. I've ensured the correct update.app from the correct Marshmallow ROM was copied to the SD in dload folder ... tried both methods and the install doesn't even get past 5%. Even tried the install from ProjectMenu. Still fails.

Is there something else I need to do? Should I try having the update.app on my internal storage instead?
[Huawei P8max] christcentric:
Ok so I held down volume up, down and power button, with the usb cable connected, and the software started installing!! But now I'm stuck at 90% .... argh! Phone reboots fine but still at 5.1.1.

:/
[Huawei P8max] Hirs_E_Fruit:
Maybe try it with the File on your Phone.

The Android 6 update has the same cust as your Phone now?
[Huawei P8max] christcentric:
Will try shortly.

I flashed a ROM with the same CUST as the 6.0 update ... but when i go to About Phone and to ProjectMenu it seems that there is no CUST at all.

Should I reflash CUST.img just in case?
[Huawei P8max] Hirs_E_Fruit:
Did you do a Force update with the Android 5 after you flashed Android 5 files?

If you do a Force update never Connect any cables!

---------- Post added at 07:10 PM ---------- Previous post was at 07:09 PM ----------

I had it once too that it failed at 90% i tried it a second time and it worked then.
[Huawei P8max] christcentric:
When I tried to do a Force Update (Up + Down + Power) with Android 5 on SD card It just said Software install fail. Phone reboots fine.

Why does it start installing, but stop at 90%, when I'm connected via USB to my computer? I don't even have HiSuite installed ... how exactly does Force Install work?
[Huawei P8max] Hirs_E_Fruit:
Did you follow the instruction from my Guide till the End and you have a fully working Phone ?

If yes did you try to search for an update via the Phone settings?
[Huawei P8max] christcentric:
Yes I followed your instructions, except for force updating the Android 5 UPDATE.app, because that step didn't work at all. Phone works fine.

Phone settings says no update available.

It seems I might need an UPDATE_CUST.app to get the phone to take the update properly?
[Huawei P8max] Hirs_E_Fruit:
yeah and here is the problem i think because without the force update after fastbooting the files via adb it isnt finished and doesnt work right.

this i think cause the problems with the update.
[Huawei P8max] christcentric:
But I can't ever get the force update to work .... why do you think this is so? :/
[Huawei P8max] Hirs_E_Fruit:
You copied the full Android 5 ROM Update.app to the root of your sd card into the dload folder, disconnected all cables and then shut down the phone and restart will holding + and - buttons?

Do your phone have CUSTC209D001 now and is working?
[Huawei P8max] christcentric:
Yes, I tried to Force Update the 5.0 Rom after flashing everything via fastboot, and the update fails.

My phone is working fine - but I cannot verify at all which CUST I am on. There is no CUST entry under About Phone, and when I go into ProjectMenu from the dialer it does not tell my which CUST my phone is on as well....
[Huawei P8max] Hirs_E_Fruit:
If you have root there are some methods to change cust maybe that will solve your problem.
[Huawei P8max] christcentric:
I have successfully rooted.. Please point me in the right direction to change my CUST! :)
[Huawei P8max] christcentric:
Actually ... big question. Do I need to relock my bootloader for the update to start installing?
[Huawei P8max] Hirs_E_Fruit:
Nope All you need is the Huawei recovery
[Huawei P8max] christcentric:
Got it ... how do i change the CUST then? :)
[Huawei P8max] Hirs_E_Fruit:
From here on i only can google and search since i am not a pro.

Maybe try to contact ajsmsg78 he seems more into it since he brought the one "custom rom" here.
[Huawei P8max] christcentric:
Thanks!
[Huawei P8max] christcentric:
Might any kind soul have the custc199D001 ROM, or has the know-how to extract the CUST.img from custc199D001? Thank you!
[Huawei P8max] christcentric:
This is entirely baffling - it seems for some strange reason I cannot change my CUST to anything but CUST199D001. I've flashed and merged different CUST partitions from a range of regions, (CUSTC100, CUSTC209), but only CUST199D001 seems to stick (as in it shows up properly under ProjectMenu) ... and this seems to hamper the B203 Marshmallow update for CUSTC209D001 on my device .... I have no idea what's going on!
