Help with factory reseting phone. - Huawei P9 Questions & Answers

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

Non-public froyo build updating issues

My phone is running build FRF33B (googling this build number returned no results at all). It was a non public build. I got the phone from Adobe as part of a (kongregate) promotion to get flash developers to edit some games so they could run on froyo, and hence I really don't know what was done to the phone before I got it (there's an unlocked symbol when it boots, and even though it's a t-mobile nexus I'm using it on AT&T's network).
FRF33B is nice and usable (but full of minor bugs which get irritating after a while), and I'd really like to update to the latest stable build, but it's not receiving any of the OTA updates, and trying to install any manually gives me a package signing verification failure.
Does anyone here know how I can update the phone? Do I need to downgrade it somehow? Do I need to root it? Any help would be appreciated.
Downgrade to erd79 would be my best suggestion and it will update to frf91 I hope that helps and if u need a update zip let me know and I can email it to u
Sent from my Nexus One using XDA App
Or just unlock your phone, put a custom recovery, and install whatever ROM you want. Look at the sticky in the development section for details.
Option 3: Search around for the FRF91 Universal update.zip, copy it to your SD card, and flash it via stock recovery.

ok I've done this, and flashed the universal FRF91, now the phone is stuck on the animated X, is this normal? Do I just have to wait or did I do something wrong?
edit: it looks like it just rebooted itself.... still not getting past the animated x part though
edit: wiped the phone and tried again, now it works... got to set up everything on the phone again though and download my apps again... oh well. thanks for the help

[Q] Problem in my Incredible S after update to 2.3.3 Gingerbread

I just updated my device to the last version 2.3.3 gingerbread.
Everything was working good until I tried to make a call.
I have full service signal, but the problem is that I cannot hear anything and from the other side cannot hear me too.
however, is not a hardware problem, because I can make calls using Skype or any other similar app without problems.
my device is in S-Off and I used ClockworkMod Recovery (downloaded from another thread here) to Install the Rom.
first, I downloaded the Rom from a chinese website and then I tried with another one (non chinese)
but...both with the same problem, So I guess is not a ROM problem.
I'm trying to update from a 2.2.1 version also downloaded from a chinese website (I bought my cellphone in China).
I have tried with some RUUs from this forum, but I'm also having the problem 170 & 171 usb conexion.
I tried to explain everything full detailed. Hope someone could help me!
(I was looking for answers in other threads but with no success)
Thanks.
Hi there,
I had the same problem as you only a few weeks ago after installing a custom rom as well going from froyo to gingerbread.
The problem lies with the radio. You will need to upgrade your radio version. In doing so you will get sound from voice calls back.
Here is the thread I followed that will show you how. At the bottom of the first post you will have the list of radio versions as well as with which RUU it should go with.
http://forum.xda-developers.com/showthread.php?t=1129014
Hope it works for you, good luck!
System92
Thanks for your quick response!, I will check right now!.
Tell you later!
---------- Post added at 09:20 PM ---------- Previous post was at 09:08 PM ----------
can you tell me which Rom and Radio you used please?. and Did you use some .exe Ruu?.
Thanks!
I am using CyanogenMod Nightly builds, which are based on Android 2.3.5 now. My radio is 20.2810.30.085AU_3805.06.03.16 (last hyperlink from the list) and everything runs well.
No I didn't use a .exe RUU
I need to bother you again!. is this version size just 78Mb?. (http://forum.xda-developers.com/showthread.php?t=1015532)
others Rom I downloaded was all above 200 Mb.
If it's like the ones on the official site, it is probably zipped (explaining the smaller size, +/- 80mb).
http://download.cyanogenmod.com/?type=nightly&device=vivo
Thank you very much System92, I just Installed the same Rom and Radio as you did and It worked perfectly!. (by the way, It's a great Rom with a fantasctic interface!)
Thanks Again!
Your welcome Bastian_n, I'm glad you got everything working!
CM7 is basically what stock Android looks like without Sense UI. Although with some tweaking you'll find that you can still customize it to your liking!
Have fun!
one last question. I cannot find the market in this version? Should I do something more? maybe patch it, or Install it as an upgrade?

Yes with the CM 7 Rom you will have to install the Google Apps separately.
Google apps may not have been included in the rom's installation. All you will have to do is download the Google Apps from HERE. Go to the very bottom of the page and click on "Download" for CyanogenMod 7.
Next, follow these instructions:
Once booted you might find some apps are missing, namely the Android Market, Gmail, etc. If this has happened, you will need to flash the Google Apps pack. To flash, copy the Google Apps to the root of the SD card, boot into the custom recovery image, and flash the Google Apps package like you flash any other ROM (do not wipe data after flashing the Google Apps package).

[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.

samsung GT-N7000 very slow and eating battery after upgrade to 4.1.2

I just joined this site to seek some help. In 2013 after the upgrade of 4.1.2 android (jellybeans) my phone became useless for use as it ran very very slow and ate battery like there was no tomorrow. I put it away and bought me another phone. But after several years I took it out again to see if I could start using it again. But not in its present condition. I read on many forums about it and obviously I am not the only one complaining. The best suggestion I have found is to downgrade it back to ICS 4.04 (Icecream sandwich). But I cannot find the firmware for Canada..I did find firmware for UK but not sure what will be the consequences if I installed that built. The other day I successfully rooted the device with SuperSu but made no difference to speed or battery drain. So I seek help in locating version 4.04 desperately. Please help revive this phone and be gentle as I am new to Android world. Cheers
SuperSU won't help speeding your phone unless you install apps to do it .. And you can flash the UK firmware if its the international N7000 without any problems .. BTW you don't have to downgrade .. Just flash the new JB firmware .. And you can flash a custom lollipop ROM .. It would be lighter and faster than stock .. Try nightowl or resurrection remix .. They are really stable

Yes, I agree with Noob, no point to downgrade your phone, you could flash UK upgrade but probably the best thing to do is to flash one of the ROM's he mentions. I flashed Nightowl 12.1.1 on my wife's Note and it has been awesome! No crashes so far, no excessive lag as Nightowl kernal supports trim (lag like she had with stock, is due to bug in emmc chip not trimming memory thus making it slower and slower the more you use it). Also repartition so there are no more issues with memory running low, slowing your phone and not being able to upgrade apps).
If you decide on NightOwl I'd install 12.1.1 (Android 5.1.1) from here
http://forum.xda-developers.com/galaxy-note/development/rom-t2938649
Easiest is probably to click the "How to repartition button" on above link and follow Savin's instructions exactly to repartition and install NightOwl, you have already installed stock 4.1.2 so you are already on your way!!!
Take a week or two to get your head around all the terms, if you have not done this sort of thing before, would be advisable. If you follow these steps you won't brick your phone (though there is always a very small risk, so you do this at your own risk!) See also NightOwl Google+ pages https://plus.google.com/communities/106990063819354862953
Read the threads and use search to answer any questions, if you still have questions ask on the thread, don't expect support via PM's (though you might get lucky a couple of times :victory: ) Watch a few videos of people flashing & partitioning too would also probably help to get familiar with stuff.

These days its a piece of cake flashing your phone with a new ROM since there is a ton of guides on xda that goes in detail .. I'm currently running cm 11.0 nightowl (Kitkat) and its fast and smooth .. Lollipop will eventually start lagging after a month of usage .. And I did try to help him using pm but I guess he didn't go online since yesterday .. Can you brick your phone while flashing through recovery ? Because I accidentally flashed a couple of i9300 ROMs and it worked after a clean flash .. There's a really small chance for you bricking your phone .. :laugh:

Yes, agreed small chance of soft brick & very small chance of hard brick these days, though this phone has the dodgy emmc chips that caused a lot of bricks ....... but that was before patches released and all the hard work from developers like Bauner who have incorporated fixes into ROMs & Kernals so it's easy for us now!!

4. boot into recovery
5. flash this kernel http://forum.xda-developers.com/devd...t/dl/?id=16862 to get an updated recovery
(this step will make your old rom unbootable stuck in the n7000 screen but you can boot into recovery with press and hold "home" and "volume+" buttons and power on your phone)
6. you need to reboot! your device now to recovery
7. you are now in the updated recovery and you need to do a factory reset (and to go sure you should also format the /system partition)

You need to download new gapps and transfer them to your SD card go here : http://opengapps.org you can't copy your installed gapps
This is great help thank you. I visited the opengapps.org and there are just too many options to select from. I have Android Version 4.1.2 and its not even mentioned in the listing...what do I get?
Also to do Nightowl they recommend to flash N7000ZSLR1_N7000OZSLR1_BRI Rom and my phone which is rooted has N7000XXLT3..should I just keep this or flash what is recommended as above..if so where do I find this rom? Thank you

The gapps you need to get has to be of the new rom you want to flash. Not what you have. If cm12. 1 then lollipop and cm13 then marshmallow. There is no need to flash another stock rom. Go ahead with the new rooms flashing procedure.

You want ARM, 5.1.1 (for NightOwl 12.1) & Gapps of your choice, though bauner recommends Micro/nano/pico, not sure why, maybe just because they are small and will leave you more space for your apps. Once you have downloaded this zip file to your PC then you can just copy file over to your phone external SD card using USB cable in normal drag & drop way once phone is recognised by windows.
Personally I would recommend you repartition as per Savin's instructions in first post so that you have plenty of space for apps and a bit left so phone does not slow down (also I think instructions are good for a nooby as they take you from start to finish, all you can do is find a few newer versions of the files he links if you like, I did this with my XXLT3, then flash latest NightOwl & Gapps for nightowl version you flash)

G800H Duos - CM13 / 12.1 / Clone from identical phone

Hi,
I took the plunge and rooted + flashed my phone last week after finding that the CM13 ROM is supposed to support a G800H dual sim. Unfortunately CM13 doesn't find either of my SIM cards.
So I spent a long time reflashing other custom ROMs to see if I could get one to work. I finally managed to find the CM12.1 ROM which finds my SIM cards but the recent and back button isn't functioning and when I try to uninstall an app the phone reboots and the app remains.
Can anyone help me get one of these ROMs to work properly?
Alternatively, my wife has exactly the same phone as me (unrooted and running everything as the it was out of the box), is there a way I can clone her device to mine then factory reset it?
Thanks in advance.
Flash the first Russian Lollipop twice. Yes, it's weird but if you downgrade sometimes you need to flash it twice to fully downgrade, then flash CM. If you still can't get SIMs to work on stock Lollipop, downgrade to KitKat then use OTA to go to Lollipop.
About cloning, to do a full clone you need to use TWRP as far as I know.

Thank you for your reply my friend.
I have resorted to using Samsung Smart Switch and re initialised my phone back to stock. I think I am out of my depth as I don't even understand your reply lol!
Thanks again!

Sorry, I will try to explain. You've used Odin to root, right? You have to use Odin to flash any stock ROM that is not to the same country as your original ROM (different CSC code). All Marshmallow ROMs are based on the first Russian Lollipop ROM released by Samsung, that's why if you flash them over other ROMs you have problems like no SIM.
Ahhh I think that might be the problem! (Yes I used Odin.)
In the instructions it clearly says "1. Make sure you have updated to stock 5.1.1" - I didn't do that - what an idiot.
I take it when you say "flash any stock ROM" I need to get a 5.1.1 stock ROM - where would I get one of those from?
EDIT: would this be suitable? http://www.youmobile.org/blogs/entr...-Android-5-1-1-Lollipop-update-is-Rolling-out
Thanks for your persistence.

To avoid issues, if you want to run any my CM13 (Marshmallow) ROM, you need to flash through Odin the first 5.1.1 Russian version, for what I said before. The common and easiest place, although slow, is from SamMobile website:

@Ifom Thanks very much I will start the download when I get back from work and install it when it finishes (some time next week).
Thanks again.
