If you were using MR v3, please be aware of post #3 in that thread that descrobes how to go by HWOTAs back to stock Android N, from MR v3
It was alse discussed many times in the same thread how to rollback from N to MM.
You can search through the MR v3 thread for rollback or roll-back and you will find posts describing the process
Generally, you must not rollback directly from MR v3 to Android A, it cannot work

First I have to go back to android N stock. Then use rollback to MM. very thank you for the help.: tốt:: tốt:

[Q] Downgrade of EMUI

Hello.
After OTA upgrade of my Ascend P7 EMUI ( Now it is P7-L10V100R001C00B133SP01 - probably from B121) i am experiencing higher energy comsumption and few other strange things. (the auto brightnes is not working the way it should .. etc.)
Is there a way how to downgrade the build, i want to try if it will help to get back the battery performance.
Can anyone please wite short (step-by-step) process for me? (for exmape 1. root your phone with this XYZ, 2. download OLD build of EMUI here ABCDEF ... )
I am totally new to this and want to try but i see that usually peopele here are talking about things they understand and i am lost in it.
Thank you for any help.
Hey man, everything's on this forum.

Just download the version you want an put it in the phone, then go with the Upgrade app.
From EMUI 3.0 there is NO downgrade!

Unfortunately in case of EMUI 3.0 is not true anymore!
I yesterday downloaded the new, EMUI 3.0 ROM (B604) for my P7-L00 and installed without problem. The new UI is promising and interesting, but it is the first developer version and still has some bugs. So, I decided to put back the old, but well-functioning ROM (B125SP03).
But I cannot do it! Nor the so-called three-button method, neither using the upgrade app works. The process starts but some seconds later the Recovery (which also has new look) says that the flashing process failed. Without further explanation, error code or something.
So, now I don't know, how to get back my previous firmware... Any idea?
Maybe You could flash old stock recovery first ?

Yes, it's a good idea. But how? My phone is not rooted.
Otherwise TWRP is not ment to flash 'Update.app' files, as far as I know...

Mayby try installing stock "recovery.img" by Adb and Fastboot and after that update.app by normal procedure.
Im not sure but I think that Fastboot don't need root to flashing recovery.
Try this solution: http://forum.xda-developers.com/ascend-p7/help/to-stock-recovery-t2893281
Does anybody know-
- is there only one version for the `recovery.img´
or we have a newer and older versions ???
I also can not downgrade from 3.0 Emui back to a lower version ( B135 / B133 / ... )
TWRP does not work anymore , because i can not EMUI 3.0 root over RootGenius and downgrade via stock recovery dload version also does not work .
When Verifing update package it always stops in different timeline installation .
Who advise you how to downgrade from Emui 3.0 back to Emui 2.3 ?
EDIT:
Please i need stock recovery from B604 EMUI 3.0
I think the stock recovery from EMUI 2.3 does not work correctly on EMUI 3.0 firmwar.
But if there are different versions of stock recoveryes .
In stock recovery menu EMUI 2.3 can not move at all , not responding to anything .
Therefore, the dload update firmware version is not correctly installed.
Z TWRP via ADB I had to revert back to the original stock recovery, so I went to install dload version 3.0 EMUI
Does it mean that there is no way to go back to EMUI 2.3 ROM anymore? !

Well I would also like to know.
I tried to downgrade P7 - L07 EMUI 2.3 B125 and error during installation.
I tried to pull the recovery of EMUI 3.0 B604 and downgrade and also without success.
Someone please advise ?

Well, I think that we should pull the recovery from the PREVIOUS ROM, and flash it before downgrade, and NOT the EMUI 3.0 recovery. Because theoretically only the EMUI 2.3 recovery should be capable of installing an EMUI 2.3 ROM.
But, according to your own experience, the old recovery did not do the job well either. So, I have no idea...

It seems that we have to wait for the newer EMUI 3.0 versions which hopefully will resolve the bugs and improve the user experience. After all, the phone can be used with the new B604 ROM too. It's just annoying that now it's worse than it used to be...
Maybe new rom with EMUI 3.0 is changing more than recovery only ?
Huawei Ascend P7-10 by Tapatalk2
So I was without a cell phone , because I have a backup of all the TitaniumBackup and then still complete backup in TWRP.
And EMUI 3.0 have not TWRP and ROOT, and go back to EMUI 2.3 not work , I'm a little more upset.
you can use any
1-Try to install by twrb a nandroid copy of b 135
or
2- extract update.App for your phone by HuaweiUpdateExtractor_0.9.8.0 & obtain original recovery then flash by adb comands
& EVERY THING WILL BE GOOD

Hi,
You can use this link to download the rollback package
http://download-c.huawei.com/download/downloadCenter?downloadId=91623&version=357533&siteCode=se
once you download it.
unzip and put the update.app in the dload folder on your external sdcard in your phone.
you have to manually create this folder in your external sdcard.
once you do this
type
*#*#2846579#*#* in your phone dialer
then you will get a menu
in that select
SD card upgrade
then you wait.
it will reboot and finish rolling back to stock.
Remember this will get you back to stock rom, but you will have to upgrade to some other ROM for your L09 after rolling back.
I do not have Huawei P9 but I have Huawei Mate 8 & Huawei Mediapad M3. I feel that there are lot of similarities between Huawei phones & that is why I feel you can make it work using these steps.
Hope this solves your problem.
For updating to EMUI 5.0
you can use firmware finder from play store.
Install the app
https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder
in the settings of this firmware finder app
switch on "add on proxy"
now go to your WIFI-settings
tap and hold your WIFI connection
modify network - select manual
there you put the following
proxy is
localhost
port is
8080
that's it save.
then go to firmware finder app
search
download the right firmware for your P9 L09 and then click on "send the firmware to updater"
now
go to settings
update -> you should see the OTA for EMUI 5.0
But don't this now. First you have to rollback and only after that go for this EMUI 5.0 update.
Don't forget. Please click on :good::good::good::good::good::good::good::good:

Cannot update from EVA-L09C432B182 to Nougat
Can anyone please help. I'm going round in circles, following guide after guide.
I'm currently running a P9 L09, running EVA-L09C432B182, after rollback
PHONE Unlocked
FRP Unlock
Factory Recovery
I've tried the firmware finder, confirming firmware ok with IMEI. My version for some reason does not have the "send the firmware to updater", and I have configured the proxy, and installed the proxy. I've tried unzipping the downloaded update.zip by firmware finder, and dropping it into the dload folder.
It seems every version I try, its fails at 5%. What am I doing wrong.
Can anyone tell me a system that works to get back to the latest stock nougat.

b329 update and no music app

Hi everybody) A few days ago i updated my branded(vodafone) mate s to CRR-L09C02B329(MM) version, during update i had a fail message and when I restart the phone I found out that the update was installed successfully, but there music app was not installed so now I can't open mp3 files on my Mate S.. If someone else have had the same issue, how you solve it? Can I make downgrade the phone to my stock android 5.1 version by downloading the firmware from officila hghuawei site? I know that I cant flash c432 versions because it's not vodafone... Maby someone has the vodafone 5.1 firmware in this case, I would ask you to share the link with me) Thanks in advance for all xda audience))
Do a hard reset to see if this solves the problem. To find all the available roms for your version download the app firmware finder from play store.

C900 is global firmware and the procedure is the same for all versions. You can flash this and then flash a 5.1 rom with C02. The file has instructions on how to do the rollback.

zan. Thanks for your help) Probably I will do this procedure but wanted to ask you: I found a full (and not OTA) verssion of the same firmware wich I have now CRR-L09C02B329(MM) Can I restart update procedure by dload? Maby the full firmware will fix that bugs..

Yes, you can. Probably this will solve the problem. I suggest you to use the installation method with the three buttons so that to do a clean install. Note that with this method you will lose your data, so make a back-up.

So the firmware size was 3Gb, yes I have already tried two procedures with three buttons and from menu by by digitting code #*#*2846579#*#* and selecting software update but nothing changes, yesterday I also looked for lollipop vodafone version, but I could not find anything.. I thought about flash role back c900 from official site and then retry to flash the same Marshmallow version... Can I do that?

But after install rollback I didn't have c900b300 as axpected, but still have c02b329 and then reflash same version has no effect) But yesterday I found c02b110 which is an official firmware(lollipop) of vodafone, (if somebody else would need this firmware I will share a link) Can I try to flash this lollipop version just over my current firmware?

Huawei p9 l19 firmware

Hi all, i have problem with my p9 l19c432 eu version. I had l19 c432b386 android n and i wanted to go bac to mm. My device doesn't have root or unlocked bootloader or custom twrp. I have all stock.
Tried to go back to mm dload method
1. Rollback package c900b300
2. Full firmware
I did step 1 and instalation was successful 100% but now when i go to about phone my android version is 5.0 NRD90M test keys, not c900b300.
I didn't try to do step 2. because i don't know so much about nrd90m.
Maybe my rollback package is not good, is there difference about rollback package for l19 and l09?
Can anyone help me with my problem? Thank you very much

That is the correct rollback. You just need to download and flash your stock Marshmallow firmware. In my case (eva-l29c636) it was B191. I had the exact same test keys in "about phone" , so just go ahead with step 2.

Thanks for your help. I was suspicious because it's not c900b300 after rollback package, it's ''NRD90m test keys'' and i didn't know can i flash full firmware when build number is nrd90m, so i stoped there. I will try to flash full firmware tomorrow.
Do i need to factory reset now or enable OEM in developer options before flashing full firmware or maybe flash rollback package again and maybe then i will get c900b300?

Yes, your data and apps will be gone. When you flash your M firmware it's going to make everything new as if you just opened the box. Sorry if you did not know that. I don't think there is any way to avoid that. I was just setting my device up and noticed an OTA update to B386 Nougat which I successfully updated to BUT then I found out that my P9 will not work on Nougat. I cannot scroll at all with it so I had to find the rollback firmware. I flashed it then immediately after that I flashed B191 Marshmallow and all is well. Nothing else. As I said, you will, however, lose all your data and I don't know if a backup can restore it for you.

Hey friend, i just install full mm firmware and everything is good now, i don`t have nrd90mtest keys, i have now l19c432b182, i found on huawei site for l09 they have rollback package and full firmware b182 so i found for l19. I think good firmware is the key of rollback, and b182 is the best for it. Thanks so much for your help!
I have only one problem, i can`t change themes. I can see themes and when i click apply it, it is successful but it didn`t change. Did you have that problem too?

Happy that it worked out for you. I have an icon on my desktop called "Themes", but when I tap on it there is nothing. I just assumed that was something that you would have to download and install from a Huawei website or get from a 3rd party app. Anyway, it does not concern me as I only care about throwing a pic on for my desktop. What really annoys me is that I cannot run Nougat on my P9
Anyway, good that you have it running again. I am on B191 and it looks like that will be all I can do.

Maybe it`s better for you my friend, emui 5 have great design and everything i must say but battery life is better on mm, bcs of it i rollback to mm. But i don`t know why u can`t get official uograde. When i rollback to mm b182 i got instant upgrade to emui 5. Maybe your version of mm is not good bcs when i had emui4.1.3 i got upgrade to b386 and now when i have 4.1.1 i got upgrade to b383. Maybe you can try to install another version of mm.

Or with 3 buttons combination and dload if you can find update, or with twrp if you have it and you will need update file too. Just search on forum tutorial for it and CORRECT update for your phone, single or dual sim whatever you have and with c900 bcs u have global version.

VKY L09/L29 C432B162- Service rom

I found link and instruction for upgrade, unbrick, back from custom rom, etc....and I hope that it will be useful for the most people. My recommendation is to use force upgrade method with three buttons. Enjoy!

I used those service roms with same method for p10 lite, p9 lite. I didnt try this one, but, I dont expect any problem because instruction is provided by Huawei. Just, read instruction, but again my recommendation is force method. Because, normal upgrade is not necessary with this rom, ota, or ffinder are more efficient. But if someone bricked phone, or has custom rom, this is the best thing for rollback to stock rom. The reason why to use forced method iis simple, because with three buttons first flash stock recovery and than stock recovery automaticly repair all system and upgrade all things.

No, no this rom is not for rollback. Only if you have issues with Nougat mentioned servise rom is usefull. But if You try rollback from Emui 8 with this yiu can brick phone. For rollback from Emui 8 to Emui 5 must use official rollback from ffinder.

How can you downgrade from softbricked Oreo ROM where FFindar can't be loaded to Nougat ?

How did you brick phone on Emui 8? Only solution is to try to unlock bootloader in fasrboot and downgrade using twrp, hwota. Method for rollback you can find here in our section. https://forum.xda-developers.com/p10-plus/development/downgrade-p10-plus-oreo-to-nougat-t3724382
Regards and good luck.

Long story. Three days was trying to get it unbricked, even it was in service shop, but they didn't do much
however, upgrade from nougat to oreo didn't went well at first. Almost an hour it was installing oreo update zip file in twrp, so I had to turn off the mobile phone in middle of process. At last, it booted to Oreo, but after a first restart (changed overall appearance from large to medium), it just bootlooped. As I had nandroid backup of nougat in twrp, I tried to restore to that, and my problems just got bigger. I tried to go back to oreo again, multile times, different builds, but no luck. Than I found the method you linked, and with great help of guys from Telegram group, it booted again in OS. Hell yes
Strange thing that happend that it didn't booted to Nougat, but in Oreo acctually. Probably LowLevel format helped to fix partitions and stuff, after that bootloader was unlocked again, As for now I have bad Oreo version (8.0.0.046) will rollback again to Nougat.
I'm try to download but on half its stoped
Hi all I used this service rom and it got my phone working again but there are problems the dialer and contacts apps do not work anymore I had to Install 3rd party apps and software update is gone the project menu won't come up when you key in *#*#2846579#*#* command. Fastboot won't let me install twrp fastboot screen shows bootloader unlocked. Frp unlock As it stands I'm stuck with a working limited phone. Does anyone have any ideas I could try

Please let me know where I can find the service ROM for a VKY-L09 (P10 Plus).
The instructions on this forum are written very garbled and not clear enough for me to take a chance and upgrade my phone from Nougat to OREO.

I agree with you all instruction for p10 plus make confusion. You can try this to upgrade to Oreo https://forum.xda-developers.com/p10-plus/how-to/huawei-p10-plus-debrand-rebrand-update-t3715288
But, you have stock emui 5 or some custom rom? Im asking because if you had stock rom you had to get regular Ota to emui 8. If you have custom just try to.use Hwota method from mentioned link. I have similar procedure with Hwota for p10 lite so it could be usefull in your case just as example to see how it works

If you have stock firmware emui 5, stock recovery and locked bootloader you can try Ffinder for upgrade too.

Thank you for your reply. First reply from Huawei contributors. Thank you.
I have stock EMUI v5.10 and Android v7.0.
I unlocked the device, installed TWRP and rooted it.
I would like to upgrade to OREO and was hoping to find a solution that will allow me to upgrade using TWRP as it is working and installed.
Please advise.
Thank you once again.
