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

If it were as simple as you write, so I here all day looking for help.
But even so, thank you for the support.
Hello forum, a little question......
This is my 2nd time of owning the 3t, now the first time owning a one plus 3t, I used a CM13/marshmallow roms., They were extremely stable, but now my question is.....
Using twrp for the Oreo, I have gone through many many custom roms, Oreo and nougat, oos and lineage etc, but what's the process going back to marshmallow?
Is it just a case of flashing the rom zip like I been doing for last month or so..... or some other way? i.e downgrading something?
I'm currently on Audax 4.0
Just take a Titanium Backup of all your apps first,
Then boot into TWRP, follow the procedure for a clean flash.
Just on a curious note, why would you want to go back to MM?
And also make sure you flash the matching firmware package for the ROM you're planning to run, unless your going for OxygenOS as this does that for you.
Firmware packages can be found in a separate thread in this forum.

With accidentally downloaded TWRP for EMUI8 and it flashed only! on ramdisk with huawei MT.
But i want Project treble OS. i have checked with treble check from play store and my phones partition style was only A, then i download AOSP os with arm64-A os .img but after install always same error! :Func NO : 11 (recovery image) Error NO : 2 (load image).
after unbrick i have installed Pixel Experience official os with A partition style only and same error.

Yes it works fine. you can also delete whole data with this recovery and reformat all partitions, after that u can mount system. but carefully.
https://drive.google.com/file/d/1rlQPRP234PoXY_yqup3oK_joOZGSIker/view << this is Oreo TWRP from xda thread(https://www.xda-developers.com/huaw...e-android-oreo-update-project-treble-support/) and it works i think. but after EMUI upgrade u can flash it on Ramdisk_recovery. not on eRecovery.
P.s i have tested on PRA-LA1 only!

try downloading a service firmware and restoring with dload:
http://www.androidhost.ru
Go to search files and search for your phone model.
Hi guys, like the title says. I'd like to flash OK Pie onto my old but still working P9 but after so, so much time i have forgotten everything I did to my phone to get to where I currently am. I've been searching for specifics to my situation but the guide to go from EMUI 8 to OK Pie is complicated enough as it is. If I have to factor in the "back to stock" procedure etc I think my brain would explode xD
So I'm looking for any links, guides, personal help or WHATEVER may help me at least get to chinese OREO 9I think I'm capable of taking it from there)
My current setup:
EVA-L09
Build number: EVA-L09C432B378
EMUI version: 5.0
Android: 7.0
My phone is from Latin America, So IIRC I unbranded it, changed it to cust 432 and flashed the latest (stock) firmware which at the time was B378.
I also have TWRP (the latest one) installed. If I got it right, I THINK I need to go back to stock recovery, flash the latest FW and go to Chinese OREO from there before trying to flash OK Pie, right?
Could somebody please be so kind as to either help me or at least point me to a thread/guide made for idiots such as myself xD that can walk me through the steps of going from my FW to stock recovery and stock latest FW?
I'll manage to get to oreo and custom after that.
I appreciate your help in advance.
Thanks.
EDIT: Forgot to mention that yes. I kept my unlock code so thats no problem
Thanks again!

General link for Open Kirin ROMs
https://openkirin.net/user_guide/openkirin-rom-installation-instructions/
P9 thread for OK ROMs (under the P9 ROMs, Kernels... collection)
https://forum.xda-developers.com/p9/development/roms-openkirin-aosp-collection-t3828806
In short:
1) You must rebrand and update your L09c432 Nougat to AL10c00 Oreo, it is PRECISELY explained in the OP posts (mainly the post #2, but read #1 - #5 to get better picture) in the corresponding thread:
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
2) Once you will be on EVA-AL10c00b540 Oreo, you have to follow the OK installation guide from the first link.
You will have to install OK Omni Pie for Android 8, not for Android 9 (there is no stock Pie for P9)
If you search for Pie in the given two XDA threads (Search box at top- right on any XDA page), you will find that many people have undergone (and some returned back from OK Pie to stock Oreo) with no problems - but it is important to carefully follow the guides, first for rebranding and installing the Chinese stock Oreo, then to install OK ROM EXACTLY as described on their site (common guide for all OK ROMs and for all Huawei phones when already updated to the stock Oreo)

Hi, thanks for replying. I'm aware of the PROCEDURE not so sure about the "how to".
Thats why I posted. Your post basically told me what I already knew (and talked about in my post)
What I'm looking for is help going from my current TWRP/STOCK/ROOTED FW. Back to full stock so I can start updating the ORIGINAL FW. I can't find any info on how to go back to stock recovery for instance. Do I need a specific recovery for the FW I'm running? Is it generic? Where do I find it? How do I flash it? Where do I get the stock firmware? (Huawei firmaware finder?) Which one do I flash? Does flashing the stock firmware automatically flashes the stock recovery? Things like that. I appreciate you trying to help but I already read and knew the things you linked to. My issue is, like I said: going back to stock before I can follow any guide to go up to oreo.
Thanks anyway!

If rooted by Magisk, there is Uninstall option in Magisk Manager, it will unroot.
Similarly SuperSU had an Unroot/Unistall option.
In both cases you can flaslh back the stock Boot partition but it is cleaner to unroot by using their Uninstall options.
From TWRP or Fastboot you have to flash stock Recovery (corresponding to your current stock Nougat firmware) to revert back from TWRP
Generally, if you download from FirmwareFinder update.zip corresponding to your current stock Nougat (must be from FullOTA-MF or FullOTA-MF-PV), unzip, then by using Huawei Update Extractor, you can extract Boot.img and Recovery.img that you can flash then from Fastboot or from TWRP to go back to stock Boot and to stock Recovery
Once you go back to stock Boot and Recovery, you can boot to eRecovery (switch off, connect to charger, keep pressing Vol+ and boot by Pow) and choose Download latest firmware and recovery
----
But in fact, since you already have TWRP, use the HWOTA method from this post to update to c432b504 or b505:
https://forum.xda-developers.com/showpost.php?p=75787151&postcount=2
You can do the same with HWOTA7 from the corresponding thread I gave you (before you will go to rebrand to AL10c00b399).
In both cases, you have to download three update*.zip files for eg L09c432b504 (must be FullOTA-MF), rename one or two of them as described in the OP posts (be careful, some people have Windows 10 that hides zip extension and they wrongly rename files to have double zip extension and then HWOTA/HWOTA7 scripts cannot find the file and fail to flash resulting with half-brick), put them to DLOAD file on the SD card and follow the guides

Thank you. Thats exactly what I was looking for. I really appreciateyour help.
Btw, no one should have the "hide extensions for known file types" checkbox marked...
Edit: Should I flash the same FW version Im currently using and then update regularly? To prevent any issues? (Cause i noticed there are some rules as to the version jumps that can be made flashing like this...

It must be the same model and cust, c432, but safer if you also apply the same build number (b387 ?)
Once you are back on stock you should start receiving OTA updates (have WiFi and a valid SIM card). Give it some time but check also manually from Settings / System updates.
As mentioned in my previous post, you can also use eRecovery / Install latest fw and recovery (if OTA coming slow), and there is a similar option in HiSuite. You will probably not need to use HWOTA or HWOTA7 to jump from clean stock b386 up to b50x

Hi again. First of all I would like to thank you agaib for your help. You made the process so much sinpler and quixk for me and I do apprexiate it.
Second, I updated to the latest "original" fw for my c432 phone OTA but then had to modify the HWOTA7 procesa so I could dl and install the latest/latest fw (because it wouldnt even register when searching for it) I used huawei fw finder to verify it and dl.
After that I went to chinese Oreo, flashed the network fixes and installed a TINY OTA update which fixed some sexurity issues apparently (thankfully it went Ok cause I THINK flashing OTA in a "converted" phone is a big nono?)
Anyways, I ended up on omni pie (the latest beta whixh is 5.2 I believe) as going AOSP was the whole point of this endeavor.
So far I'm LOVING it. Its such a refreshing thing not having to deal with all the bs OEMs bake into their roms... But Im experiencing a couple of issues as well. Not sure if its the rom, my phone or the android version (particularly my issue with battery life since I was having issues with the duration way before I updates, actually that was one of my motivations for updating since I read that pie had better battery management)
Anyway, my issues are as follow. Hope you can help (once again)
Battery life SUCKS (like really, it went from bad to terrible... Not sure if stock oreo would make it better, or perhaps omni pie needs some optimizations?)
The camera (huawei one, not sure about the aosp) has issues. Multiple issues. The biggest one being that if I try to go from back to front camera the app locks in a black screen and I have to go into the app, delete data, reboot the phone and relaunch it (and that doesnt fix it everytime)
The last issue is with pop messages from apps and/or settings. Sometimes, when installing and app and/or changing aome setting a white popup shows up with ONLY an OK option. I cant read anything on the popup. Everything is white. Not sure if its an issue with the theme (I changed from default to "hell" or something like that) but it is VERY annoying not knowing what youre agreeing to.
Last but not least I have a question about the stock rexovery, factory reset and flashing new versions of omni (if and wheb they come out)
In one of the steps for flashing omni the guide asks to perfomr a factory reset from the stock rom. Thing is, it doesnt work. I mean, when I confirm the factory reset the process starts and approximately at 15% an exclamation sign appears and the process percentage stops working. I can reboot the system and everything works fine (using the phone to post this actually) but Im left with that feeling of not knowing why something failed... You know what I mean? Is that nornal?(the failure to factory reset, not the feeling ) also, does factory wiping the phone removes root access? Or does it only renove magisk manager?
Also, if I ever wabt to update the rom (not change it mind you, but flash the next beta or stable or whatever they come up with) do I need to flash the stock recovery again? (Currently rooted with magisk) or is it a separate partition? (Sinxe I had to modify the ramdisk and not flash a custom recovery) also, will I need to do the whoooole thing again? (Backup everything, restore tk factory etc etc) or is it just like with lineage for exanple where you could flash and updatr and keep your data untouched?
Thanks for EVERYTHING my friend. And I hope you can answer my questions (particularly the ones about battery life and thebfactory reset issue since Im planning on doing one last factory reset before settling with the rom. Just waiting for my new micro sd. The one that will stay in the phone)
Sorry for the typos. Writing this huge post on a phone is a PITA.

The last issue is with pop messages from apps and/or settings. Sometimes, when installing and app and/or changing aome setting a white popup shows up with ONLY an OK option. I cant read anything on the popup. Everything is white. Not sure if its an issue with the theme (I changed from default to "hell" or something like that) but it is VERY annoying not knowing what youre agreeing to.
Last but not least I have a question about the stock rexovery, factory reset and flashing new versions of omni (if and wheb they come out)
In one of the steps for flashing omni the guide asks to perfomr a factory reset from the stock rom. Thing is, it doesnt work. I mean, when I confirm the factory reset the process starts and approximately at 15% an exclamation sign appears and the process percentage stops working. I can reboot the system and everything works fine (using the phone to post this actually) but Im left with that feeling of not knowing why something failed... You know what I mean? Is that nornal?(the failure to factory reset, not the feeling ) also, does factory wiping the phone removes root access? Or does it only renove magisk manager?
Also, if I ever wabt to update the rom (not change it mind you, but flash the next beta or stable or whatever they come up with) do I need to flash the stock recovery again? (Currently rooted with magisk) or is it a separate partition? (Sinxe I had to modify the ramdisk and not flash a custom recovery) also, will I need to do the whoooole thing again? (Backup everything, restore tk factory etc etc) or is it just like with lineage for exanple where you could flash and updatr and keep your data untouched?
Thanks for EVERYTHING my friend. And I hope you can answer my questions (particularly the ones about battery life and thebfactory reset issue since Im planning on doing one last factory reset before settling with the rom. Just waiting for my new micro sd. The one that will stay in the phone)
Sorry for the typos. Writing this huge post on a phone is a PITA.

This small OTA bringing Patch02 over b540 installs even over TWRP (but that was not the case for OTA from eg b535 to b540)
Cannot discuss/compare battery for Omni Pie, since not using Omni
Problem with Camera app does not show on stock Oreo. Even if the app was somehow ported from Huawei, there are maybe problems with integration to Omni.
Various Huawei/Mate models come with different cameras, but there is only one OK Omni ROM (with one Camera app) given to work on all Huawei/Mate models
Btw, somebody else also complained about issues with Camera (and GPS) and decided to go back to stock Oreo.
Similarly, issues you described about black notifications or so must be related to the custom ROM, theme or so.
As a general rule:
- for installing OK ROM, you flash System partition, and nothing else
- you also wipe Data partitiom (containing all your installed apps, incl Magisk Manager, also containing your user settings)
It does not affect any other partition.
Therefore, changes given by NW patch persist - without, you will have (also in that OK ROMs) problems with SIM card(s) and connecting to the network
Also, Magisk, which was flashed to Ramdisk, persists. You must only install Magisk Manager again, because it is user apo, installed to Data partition that was wiped
You must check on the OK side how they advice installing the updates of OK ROMs
(It is questionable if they will get updates any more, since OK team switched to development of ROMs which install over the stock Pie, whereas on P9 you have no stock Pie - only Oreo, and most likely, we will never see stock Pie for P9.
Just check when OK team released last ROM for stock Oreo, and compare with their releases of OK ROMs for stock Pie:

Hence IMO, for updating the OK ROM (if/when it comes), you will again just need to flash its System and to wipe Data (and then to reinstall user apps like Magisk Manager).
Hopefully, you can backup and restore some apps and settings by Titanium.
Whether you don't need to wipe Data for such update - check from the OK support.

Flashing stock Android 9 from Android 8 (phone doesn't get OTA updates). In case something fails, can I use a TWRP backup to go back to Android 8, exactly as it was? Thanks
I have used before a TWRP backup before to get my phone back. and it did restore to exactly to how it was before. But since it was a long time ago where things were much simpler (Back in android 4.4.2 which didn't had as many as of nowadays security measures or complex boot sequences, like no a/b slots or phone encryption) there's no guarantee...
