Need your help with rollback L09 to stock EMUI - Huawei P9 Questions & Answers

Hey,
I need your help with going back from RROS to stock EMUI.
Im trying this since a couple of hours now but I dont get it.
So I started flashing RROS with the new TRWP everything worked fine but the battery drain was to big so I decided to restore to the nandroid backup I did before flashing the custom rom.
But there was the point I did anything wrong so... My device just bootloop now and I dont know what to do.
I tried the dload option to rollback to stock for so many times and in the end I got a bootloop again so can anybody help me with this sh*ty smartphone?
Id be so glad if anyone could please help me, Im so desperate :/

Why you didn't ask first for instructions in the RROS thread - supposidely the RROS authors and users should know how to go back (they are subscribed to and they read their thread)
I'm not sure if DLOAD method works from RROS.
If you still have TWRP, you can try

Thanks a lot Im goona try the first one but Im not sure its really working because I used a nandroid backup of another user from version B384 and flashed OEM info packages.
I dont rollback from full RROS so I dont really know in wich thread I should write.

First method, HWOTA, does not recover OEM Info - you should have never flashed Nandroid backups from another users.
I would suggest to go anyhow back to stock Android N, then to do rollback to MM and back, by OTAs to Android N (stock ROMs)
Btw, what was your orginal stock ROM, EVA-L09 c432 b384 or what (L19, etc)?

I got a L09, I dont know my stock and the ROM I moved over to RROS too.
However, Im going back to RROS with the nandroid backup I did before all this **** and then Im trying HWOTA.
Rollback doesnt work, I tried it with the stock and nocheck recovery, two times package errors.
Edit: restoring nandroid backup of RROS failed, with extractTarFork() error 255.
Im starting now with the HWOTA method after flashing the rom again without backup.

HWOTA method requires that you use ZIP corresponding to your original stock ROM you had.
This is because HWOTA actually uses no-check Recovery to force DLOAD to the chosen stock ROM, but DLOAD does not recover/reflash all partititions, they must be original/in sync. If not, DLOAD (as part of HWOTA) will probably fail.
You should at least know what was your original cust for L09, was it c432, c185 or c636 - to choose the corresponding HWOTA ZIP.

First of all thank you!
So... like I understood your post there ist no way for me any more to use DLOAD or HWOTA because I dont have any part of my stock ROM on my phone. Well, that doesnt sounds so good.
But what can I do then? How can I go to stock when I dont can use DLOAD or stuff like this??

Try with HWOTA and then try with rollback, maybe it will work
And/or try the second method from above (that one I never used).
Actually, that second method also utilzes rollback, to clean/restore all partitions.
Hence, it is important that you reach a point (having, even not fully functional, stock Android N) to execute rollback

[Q] Se7en-ROM (EMUI3.0) - Downgrading

Dear XDA-Members,
I am one of those people, who flashed the Se7en-ROM with EMUI 3.0 without deeper knowledge. I know it was stupid and I really wish I hadn´t done. But anyway...
The history:
- Flashed Se7en-Rom (EMUI3.0) following the guide
- Distorted voice -->trying to revert back to EMUI 2.3
- So flashed TWRP, but TWRP doesn´t work(recognizing no touch, freezed, false temperature displayed), so no restore possible
- Flashed stock recovery
- Tried to force update, but fails (I tried nearly every downgrade-Update.app available on XDA)
- Flashed back to CWM, tried to flash se7en-Rom (emui 2.3) -->bootloop
- Okay, flashed back Se7en (EMUI 3.0), no distorted voice(?!:good, but can´t follow the instructions, because I couldn´t flash the update.app (fails). So there are no gapps, they do not appear even after flashing manually. Also restoring with Titanium Backup doesn´t work.
So I´d like to get Gapps running or to downgrade..
Yesterday I saw that the internal storage is showed with 3,92GB (setting->storage). Due to this I obviously changed the partitions. Is there a non-dangerous way to repartitionate?
Just trying seems to make all even more badly, so thank you very much for reading this! I would be really happy for every tip.

There's no need for you to worry. Just follow this steps: http://forum.xda-developers.com/ascend-p7/general/reverting-emui-3-0-to-2-3-t2934277
Your problem will be resolved including your storage problem. Don't even try to re-partition your storage manually you will regret it at the end.

Doogee X5 SP Flash Tool questions

First of all, sorry if this is the wrong place for the question. I just registered, so I'm not very familiar with this.
Okay, so I'm gonna try to make this as short as possible: I rooted my Doogee X5 with Kingo Root, then installed a wireless update(believe it's called an OTA), which ended in an error. Every time I boot up my phone, it just leads me to the recovery mode. I might send it for repairs because I still have a warranty(although I don't really think they're gonna do much when they see the root), but I'd like a different way to fix it if they don't. AKA SP Flash Tool(if there are any other ways to fix it that are less risky, please do suggest them).
Now to my questions: Are there any things I need to be careful about during flashing? If I flash the wrong ROM, do I have another chance? Also, if there is a tutorial around here that might be useful for me(as detailed as possible please, so I can see what needs and doesn't need to be done), it would be much appreciated to link it. Thanks in advance.
EDIT: Sub-question, what are the recommended images to flash to fix my problem?
SP Flash Tool is right way to go. Download latest version, and download latest ROM version for your phone.
But do not make a mistake like me. First do backup of everything. If you do not make backup and format phone, you will need to lose some time and reconfigure things manually.
SP Flash Tool can make backup for you. You will need scatter file, and option Readback in SP Flash Tool.
After that you can download latest version of ROM.
I agree with giga. Plus one question dude. How you backed up the devices rom since the sp tool hasnt this option or i cant noticed and find. I want to root install custom recovery and also back it up. What should i do ? Is there a correct order if these steps ? I dont want to brick the device, i dont use a second one. What do you suggest me ?

Search on P9 ROMs section for HWOTA7
Or older/simpler HWOTA - you will find instructions in Magic Rainbow v4 (also P9 ROMs section) - MR v3/v4 had clear instructuns how to go back to stock, applicable also to other P9 Nougat custom ROMs
Of course assuming that you don't want to go from Chinese Oreo back to Nougat - then the procedure is different but it is also clearly described in the corresponding HWOTA7 thread OP instructuns

Help with factory reseting phone.

Dear XDA community,
Currently I have a Huawei P9 with Magic Rainbow 3 ROM installed. I am really unhappy with it since my phone has slowed down and my battery is draining too fast (20% or more in 1 hour while just listening to Spotify).
I relise that I will lose root and all my files, but I wish to revert back to fresh official Huawei version of Android as if it came out of the box.
My problem is that I tried to do that a while back (and when I failed I had to download the Magic Rainbow 3 ROM) but every time I installed the official version, my phone would be missing all the Huawei apps, the camera app and bluetooth wouldn't turn on and just felt like a crippled version of Android.
If anyone would be willing to guide me through the process of reverting I would be really grateful.

There are clean and easy instructiobs (and in the Magic Rainbow thread itself!) how to properly flash back to stock ROM
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
However, your problem should not be in the Magic Rainbow (an excellent ROM, saving the battery) but in the latest Google Play Services update, see in this thread (not just this post but alao tge earlier ones)
https://forum.xda-developers.com/showpost.php?p=76549662&postcount=33
Besides, there is a newer MR v4 - see the thread behind the first link. Installation instructions are in its post #1

Thank you for your reply. I'm puzzled as to which firmware I should use. I can only see I'm EVA-L09 and on MagicRainbow. I also don't remember on which firmware I was before going to a custom ROM. Is there any help for me?
I'm very sorry for bothering, but I'm a noob and shouldn't have messed with the phone.

Yes, you need to know which stock ROM cust and build you had before, to flash the same by HWOTA.
I think I saw instructions about a hidden file you can read it from, you need root to access the file (MR is prerooted), but I don't remember where it was - you can ask in MR thread
Btw, you can also upgrade from MR v3 to v4

I guess my best bet would be upgrading to MRv4 and hope it changed enough so my battery and performance get better (maybe a factory reset will also help). Also, I've tried searching for MRv4 on XDA forums, but can't seem to find the thread. Could you please link me to the site with instructions for upgrading to MRv4?

One last question. I just want to inform You that I have succesfully reverted back to official firmware. But it now says I have an update b399 and when I download it and try to install it I get the error: "Software install failed. Failed to apply the differential update file. Please download a package in erecovery mode." But even when I try to download in eRecovery I get the error that it can't download the package.

You can again use HWOTA and upgrade to b399 and after that even to b502
Of course, for HWOTA you will have to install TWRP again (and unlock Bootloader if it was locked now)
---
You have 'reverted' to b394 but that probably wasn't the proper build you had before installing MR v3....
You can do Settings, Advabced Settings, Backup and Reset, Factory reset with internal memory (it can be also Factory reset with Internal memory from eRecovery).
Then, when you receive notification for OTA b399, find in that OTA updating screen (I don't know now how exactly it looks because Iam on MR v4 but I was doing that previously) the option to download and OTA upgrade with Full package, not with default Differential package

TWRP-Installation went badly wrong....

Hello Guys!
My device:
Redmi Note 9 Pro (European)
Bootloader-Status: Unlocked ✓
Root-Status: rooted ✓
Recovery-System: doesnt work x
Fastboot-Mode: does work ✓
As described above i stupidly flashed the wrong TWRP version to my device. Now i end up in a bootloop with the error code "System has been destroyed" and i can't get into the system anymore. Another big problem is that the device can't detected/recognized anymore by any console using adb and the Mi-Flash-Tool also can't see it as well ...
Does anyone have any solution or ideas for my problem? I bought the phone recently and don't have enough money to buy another ...
I would even pay money for the solution.
Someone said i have to flash the stock partitions back again. But which tool/method allows it me to flash the stock partitions back again? I have no idea how to flash ANYTHING without using adb or recovery mode ...
Thank You In Advance
"System Has Been Destroyed" means only three possibilities:
Partition SUPER has been modified,
Partition VBMETA has been modified,
or Partition CUST has been modified.
Just flash the stock partitions back again, but from the same version already present on the device.

ok thank you very much so far! I can see it's not possible to flash stock partitions using adb. can you tell me which tool or method i have to use to flash the stock partitions back again?
You can't flash partitions using adb.
Try spflashtool.
So was busy the whole day finding a solution.
My goals so far:
-installing spflashtool
-installing drivers for spflshtool
However i don't find any site where to download/buy stock partitions for redmi phones ...
Can you suggest a source for them? Are custom firmware's and custom ROM's the same ?
Have a nice day!
{Mod edit: Quoted post has been deleted}
I spent almost the last day watching videos on youtube on it and i wouldn't post something here if i had found someting....
Can You at least please tell me - Are custom firmware's and custom ROM's the same ?
All steps for spflashtool are same for all devices.
Keep trying.
Can You at least please tell me - Are custom firmware's and custom ROM's the same ?
Thats all in have to know....
you simply have to reflash your stock firmware again, Google your device firmware and phone Model, or search your model on androidhost.ru and flash using something like team mt multitool
