going back to stock - Huawei Mate 9 Questions & Answers

I flashed TWRP and unlocked bootloader, I am on mha-l29c636b158. How can I return to completely stock? I want to receive updates via ota because I read that there is a new update to fix the touch screen not being responsive. Or is there a flashable stock zip update I can flash?

I spent that past two days rooting and flashing the one rom I could. Had to ignore some Chinese. I am USA 567B167. Got into trouble a number of times. This phone is funky compared to all the rooting I have done. I booted into erocovery, downloaded stock 2GB, wiped and was back to current stock without issue. It bootlooped if I didn't hard reset and wipe cache.

So you just booted to erecovery and from there it automatically downloaded the stock firmware?

You can return stock by use dload update.

yes. I did it twice. that is how many times I got into trouble and was the only solution. It worked great as it gives you the ability to log into wifi with a keyboard present to put in the password, then downloads the stock current rom and flashes it. You have to format data and wipe cache yourself.
Miss Wugfresh root tool. Get you out of any trouble.

It says getting package info failed in erecovery

Erecovery only work for Chinese firmware.
Use the guide above and yes you can receive ota.

I also received the same message. Getting into recovery was inconsistent for me even with TWRP. Sometimes it would do the auto downloaded and fail thing and other times it would go into TWRP. You need to get where you have three choices and pick erocovery and push the start button. This brings up the restore ability. Worked perfect on the USA model.

Are you sure ur not using a paid service?
That's a good news, that was only possible for Chinese firmware,hope they extend it to all regions.

Completely positive. It happened by accident because I got in a bad place with HRT rom. Came out completely stock and current when no upgrade need. Then I rooted stock and somehow lost gapps including keyboard. Did it again and back to stock. All in erecovery. No other programs or files. It did a 2.5GB download, flashed in Emui and rebooted like when I bought it.

Sorry for the no noob question: I just got my mate 9 and unlocked bootloader and rooted it. Recovery is TWRP 3.0.2-2.
Where do i find this erecovery? Couldn't see any download option in TWRP and even Google didn't know that term. Could anybody please explain step by step how to revert to stock (for the only sake of getting OTAs) once the phone has unlocked bootloader and is rooted using the method from xda with modified boot.img?
Or is it even possible to take OTAs while being rooted with system read only? On my previous phone, the Asus Zenfone 2 this was possible.
Thanks a lot

Thanks for the quick answer. Let me clearify what I understood : this erecovery is available only on the PC?
So basically I wait in rooted state until I receive the next OTA, don't take it but switch off the phone.
Then connect it to the PC and boot it up by holding the volume up + power key.
Then what happens exactly?

Booting the phone while plugged and with volume up will take you to erecovery on ur phone.
There you connect to wifi and the firmware get downloaded into ur phone

Ah ok, this erecovery is still available on my phone even if I already flashed a custom recovery, right?
Then after downloading the firmware, erecovery will flash it and overwrite root and lock my bootloader again, correct?

F2 to HE update?

I bought my S3 used and it was already unlocked but from what I can tell still had the stock ROM (base version says it is I535VRLF2 but DEVICE STATUS says it is modified). When it powers up, I do not get a CWM or TWMP screen -- it goes directly to the normal startup so I am not sure what the previous owner loaded/did. I do not see any folders in the root folder (using ES FIle Explorer) for CWM and nothing in DATA/BACKUP (EDIT: just saw build number is VRALG7)...
Today I got a notice about an OTA upgrade (to HE) and got help on how to freeze it (as I did not want to lose root and all the customization I did to some files) but now I am wondering what changes were made from F2 to HE. I did find a post that talks about the HE upgrade.
Was F2 the previous OTA for the S3, or did my phone miss other OTAs? And if so, I am missing out on some important changes where I should let the OTA happen and then go and unlock the phone again? I read a number of threads about 'the new radio' which I assume is software to improve the phone or WIFI. Am I missing out?
Thanks

I don't think you are missing out on anything to be honest. I did update mine and reroot without any issues, but can't really tell a difference. I would still do it so I can have the latest update on my phone since this one doesn't lock anything that we can't get back into.

There has been only three official releases, F2,G7,and HE. Since you are at G7 I would go ahead and OTA HE. Latest ROMS are based off of it plus you will have all the latest firmware and modem.

Thanks for the reply. Will that break either my root or unlock (actually, I am not sure what state this phone is at since I did not do it -- I do find SuperSU in APPS, and have granted SuperUser to programs like Titanium Pro but there is nothing for CWM or other ROM managers...)?
Frank
If you did an OTA to get to G7 your root is probably gone. You said you have Titanium installed, try to use it. If not rooted it won't work and will advise you so. If this is the case do the OTA to HE and then you will be up to date stock ROM wise.

No, sorry, I must not have explained it correctly. Titanium Pro, ES File Explorer, etc works fine, and I can edit/delete/freeze, etc no problem. So it is still rooted (or unlocked, I can figure out which is which). I would update to HE but only if it did not mess up what I have....

Ok I understand now. Root and unlocked are two different things. You can flash an HE ROM and not lose your root. Unlock in your case I think you are referring to the bootloader. It will have to be unlocked prior to flashing custom ROMS. Get an app called EZ Unlock from the Playstore and it will unlock bootloader for you if it's not unlocked already.
I recommend CleanROM 3.1 if you decide to flash. Hope this has helped you some.
I'm trying to revert back to custom because i lost my IMEI but the process I was following required me to flash "VRALF bootchain" 2x and then flash "HE package" but i dont know where to get the HE package and i tried flashing root66 and VRALHD but they both failed can someone help me?

The only way to get stock HE currently is OTA.

I am not interested in loading any custom ROMs (although I am hoping we get the official JB soon). The only thing that is of interest to me is to be able to run certain programs that require superuser access (e.g. Titanium Pro) and to be able to edit and delete files in the root directory. So I assume all I need is root, and I don't want any OTA updates to take that away (or overwrite files that I have modified or edited that deal with the OS). Maybe that is why I cannot find any reference to CWM -- the previous owner only rooted it but did not unlock it....

Got just the thing for you. First test to make sure you have newest CWM. Power down, Hold volume up,home button,and lock button at same time until phone flashes twice then release. This will put you in recovery and you can see what version you have. The latest is 6.0.1.2. If not you can find newest version or a touch version right here at XDA. Then if you want just a rooted HE version here you go.

Or you can download GooManager and flash TWRP for a more user friendly touch recovery. :laugh:
And flash the same rom from Scott.

OK. I have 6.0.0.8 right now. I am surprised it was there, as with my Nexus and my TP on a cold boot it would show CWM at startup. And there would be folders in the root directory (/CWM). But yes, I have CMW.
And OK on now being able to download and install a rooted HE. But most are saying it either does nothing or makes the phone run a little hotter, so unless I see a pressing need, I will just stay with what I have.
Thanks again.

I had tried TWRP with my HP TP and although it has a nice interface, one time, on loading a new nightly, it TOTALLY messed up my TP. I thought it was bricked. I ended up having to do a complete restore back to WebOS using WebDoctor and a lot of what I thought was code-level input via the PC trying to bring it back to life. Since then, I have only used CWM.
Thanks for the input though!

It is personal choice. I have not had any problems with it and have been running since device was released for pre-order. I run whatever recovery seems to be most stable for the device. CWM for Tbolt. Amon Ra for Rezound. And now TWRP for S3. Have seen more bricks and failed flashes contributed to CWM so I stick with TWRP.

The OTA installed with a custom recovery installed? Interesting. Usually OTA's fail if anything but stock recovery is installed. I only lost root but restored root with OTA Rootkeeper with stock recovery. Good to know that custom recovery can be installed and still get OTAs!

[GUIDE] Debranding to C432 and updating to B361 (Nougat) for EVA-L09

Like many people here, I was eager to get onto Android 7 but the issue I faced was the fact that I got a branded phone and a long wait till I officially get the Android 7 update. Looking through this forum I was very put off on manually updating it to Android 7 with so many threads about bricked phones. However, the urge to get onto Android 7 was too great so ultimately, I decided to do my research and just do it. I am not new to flashing and custom roms but I am new to Huawei but I had confidence that I will recover if I do brick my new P9. In the end (after a few bricks and a couple of mild heart attacks), I got there and to get there, I needed to grab information from multiple threads. So I have decided to put together this guide so people have a singular guide to debrand and get onto Android 7. Below are steps and threads I took to debrand my C34 to C432 and update it to B361.
What listed below is what I did to get onto Android 7, this may or may not work for you so use this guide at your own risk.
Using this Guide - Please read through this guide BEFORE attempting it. There is a lot of large files to download so I recommend that you download everything you need before you make a start and a fast and reliable internet is strongly recommended.
Prep Work
- Backup all your data because your phone will get wiped.
- Make sure you have the stock recovery already flashed and make sure your phone is not rooted (may not be necessary but this was the state my phone was in).
- Get yourself a bootloader code from Huawei. Go to http://www.emui.com/en/plugin/hwdownload/download, you will need to create a Huawei ID if you haven't already done so. Click on the Unlock Bootloader link and fill out the form, you should get a bootloader code almost instantly after submitting the form.
- Download and install HiSuite (http://consumer.huawei.com/minisite/HiSuite_en/index.html).
- Download the SRK Tool from here: https://forum.xda-developers.com/showpost.php?p=66737472&postcount=2
Now lets make a start.
1. Download and flash the dload-huawei-p9-eval09-eva-b136.zip from this thread: https://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818. Instructions on how to flash this is in the first post. After flashing, you should be on the L09C900B136 firmware. NOTE: If it boots up to a white screen asking you to enter password, reboot into recovery by holding volume up when you powering up your phone, do a wipe partition and factory reset. You may need to reboot your phone a number times before the phone boots up correctly.
2. After flashing and booting into the L09C900B136 firmware, you will need to unlock your bootloader and install TWRP. You can use the SRK Tool to do this, please have a look at this thread (https://forum.xda-developers.com/showpost.php?p=66737472&postcount=2) and watch the video on how to do this. NOTE: You only need to unlock bootloader and install the TWRP recovery.
3. After your phone has been unlocked with TWRP recovery installed, download oeminfo-huawei-p9-eval09-c432.zip from this thread: https://forum.xda-developers.com/p9/development/c432-oeminfo-flash-twrp-t3384903 and flash it via TWRP. To get into TWRP, power off your phone and go into recovery by powering up your phone while holding volume up.
4. Once you flashed the oeminfo file via TWRP, power off your phone and repeat step 1. So you need to flash the dload-huawei-p9-eval09-eva-b136.zip file again via the dload method (power on the phone while holding volume up and volume down). NOTE: When you flash this firmware again, it will lock your bootloader (Fastboot will tell you that the phone is unlocked but I assure you, your bootloader is locked) and restore to stock recovery.
5. Once your phone has booted back up, go into the phone settings and you should see that your phone is now on the EVA-L09C432B136 firmware. To test that the firmware is working as intended, go into the phone settings and go into Updater, updater should pick up the B182 firmware and you should be able to update it to B182 without an issue.
UPDATE: A number of people has reported that they are getting the B166 update instead of B182, if this happes, do a wipe partition and a factory reset after updating to B166. When you get back in, you should be able to update to B182 via Updater in the Settings menu. If this method does not work, you can manually update to B182 by following the steps here: http://www.carbontesla.com/2016/11/download-huawei-p9-b182-marshmallow-update-europe/
6. After your phone has rebooted and you are on the B182 firmware, you need to now update the firmware to B361 via Huawei Updater 2.0 using this guide: https://forum.xda-developers.com/showpost.php?p=70594380&postcount=2.
After all that is done, you should now have a debranded UK C432 P9 running EMUI 5.0.
Special thanks to @paulobrien, @somboons and @KrAzYtHeBoY for their guide, tools, files and video to make this update possible.
Props to you sir. I will try this when I get back. I don't have any doubts now after reading this guide.

Its very likely that debranding will void your warranty since you will need to unlock the bootloader and flash a firmware that is not the same as your original model.

Thanks for the guide. I've recently been battling away trying to go from C34 to C636 - still never got to the bottom of it.
Is that a typo in your post for your original model number - C43? Or did you come from Optus AU C34?
Either way - have you had any network issues in Australia with the new firmware?
Cheers.

Yep, its a typo, thanks for pointing it out. I have no issues what so ever, everything works perfectly fine and there has been no drop in cellular reception, wifi reception, GPS accuracy and etc. Apart from the build saying L09C432, you wouldnt be able to tell the difference.

Legend. Appreciate the reply - it was tough to find experienced Aussies on the same starting build/carrier.
Now I just wish I hadn't wasted the time going for the Asia Pacific variant!
Will get stuck into it this evening.

Great guide! Reading through it seems easier for it to be managed through hisuite/windows but I have a big issue. For some reason my computer won't recognize my phone! I installed the beta and am on build number EMUI-A168-L09C900B040SP11-log and since doing this stupid move I have been unable to connect to a computer nor install other builds or rollbacks directly on the device so I just feel like smashing it and claiming the insurance. Is there any advise that could be offered to maybe force a firmware upgrade?

I cant promise you that the guide I put together will work for you. If its a Nougat beta firmware then you would be technically doing a rollback to MM. Just a bit of a warning, a lot of people who try to roll back to MM, usually encounter problems, annoying problems. Unfortunately, I dont have much experience with this phone or how Huawei does things so I cant help you much. If I am in your shoes, I wouldn't attempt to debrand and flash Nougat using this guide.

I went from a full factory reset on B136 to B182 to B361, not once did I stop to check to make sure all of the apps are installed, I only started setting up my phone and have a browse once I was on EMUI 5.0. It may be un-necessary to flash B166 if flashing B361 give you themes and icons.
If someone could double check on this when following this guide and report in, that would be great. I am not willing to test it out by rolling back to mushmellow.

Are you on an unbranded device?
If so, the official Huawei support page offers a rollback package if you updated to the Nougat beta.
Make sure you go to the page specific to your country.

Broken themes/icons seem to be caused by missing assets in the /CUST/ partition. I managed to get around it on my broken C900 firmware by separately flashing the /hw/normal/ package specific to the build. These can be found in the filelist.xml in the [WAREHOUSE] post - but you need to change the URL manually to grab the file.

So B361 will? Didn't know that.. Didn't want to risk it it took ages to download.. I had 3 folders in B136 but I flashed it via dial pad options.. Not 3btn..maybe if I would flash via 3btn it will give it back then and I wouldn't need B166..
Cannot be bothered.. It's done now..
Nougat best..

It makes no difference if you use the 3 button method or via the dial menu, both does exactly the same thing. I am only assuming that Themes could be installed when I flashed B361, I was not paying attention to the apps that was installed but I think this may be the case because I believe the Theme app was updated for EMUI 5.0, again all assumptions here.
Can I jump directly from b136 to b361?
Thanks in advance.

It's from Vodafone unfortunately
I've followed the guide as far as step 5. When I got there, I ended up getting an update for L09C432B166 which installed fine, but I'm not getting the B182 update. Anyone else run into an issue like this?

No you cant, you need to get to B182 before flashing B361.

Try wiping partition and a factory rest and see if you get the B182 update. If not, you can download the B182 update and flash it via dload but if that does not work, you can try doing it via the Hisuite and Updater method.

Uninstall TWRP and Root

How do I uninstall TWRP and unroot my Honor 8 so I can update to nougat. I have FRD-L04 EMUI 4.1
When it says your device cannot be trusted on boot, just hold down volume up (not before that warning comes up), then select download and install latest package. Your phone will be relocked and everything will be stock.

No for some reason when you hold it while on the warning screen it will bring up Huawei's E-Recovery instead of TWRP where he can download their firmware and the phone doing everything to restore it. I don't know why it does this, but you can also see it in action too with your phone. I accidentally did it when I installed TWRP at first, held it down and then it brought up E-Recovery instead of TWRP, but holding power and volume up before the warning screen brings up TWRP.
I guess Huawei wanted you to always be able to restore your phone if everything got corrupted.

Use the rollback package from Huawei
There is also a instruction how to rollback.
But you neer a external sd card for it.
Just search for it here in the forum or on the Website it self
Here is a small instruction but first make sure which model you have (frd-09/04....) The second and third post i think
https://forum.xda-developers.com/honor-8/help/totally-screwed-honor-8-t3556678
Download the right rollback stuff like firmware for your model!
If you need a deeper instruction PM me and i can help you out

Stuck in ERROR MODE

I already wrote something like this in a similar thread, but for another device (read the device name wrong), so I thought i should post it in the right place.
I have been playing too much with stuff that i probably shouldn't have been so hasty about. So i have finally arrived here on the ERROR MODE (with unstoppable boot loop), which looks exactly like the bootloader only it says ERROR MODE instead of whatever, where i can't get into any other type of recovery or fastboot mode, no matter what button combinations i do. I previously could get to the fastboot mode, but i was still stuck so..... I made the very wise choice of relocking (since i hadn't tried that) my device, and now I can't even access fastboot (nothing. tried every button combination i can think of). So I am sitting here wondering if this is the end of the journey with my... relatively new phone... So, yes. No way of accessing anything and my phone is in a reboot loop i can't stop. Only thing is the error code i get "ERROR!":
"Func NO : 16 (lpm3 image)"
"Error NO : 1 (security verify failed!)"
Is there hope? or no?
Also noticed the light flashes green 3 times then red 1, then continues this pattern. Idk if that's useful or not.
Here's a pic.
It doesn't seem to have fastboot connection here, either.
OP were you ever able to fix this issue?
@Kimuchuu its not clear from OP had you relocked your bootloader if yes then you cant modify your system you need to have unlocked bootloader inorder to perform system modifications.
Ah. Yes, unfortunately I relocked it. I ended up sending it to service with no hopes of getting it back working, but they sent me a brand new one. So that's that.
I guess I was lucky, but really there was not a single thing I could do at that state.
You can be really happy that they sent you a new one, but it's not a unique case, in CZ there were few people who had same or similar issue and Repair service gave them new phone too.

I also had this problem, trying to screw around and force a ota update via flash fire onto a modified system... Reached rhe same sddor mode, luckily I was able to manually flash all the partitions back to stock using ADB and finally once all partitions were back in order it allowed me to enter recovery mode and download and install system software threw recovery... Took me about 4 days of non stop tinkering to finally get it working again, I had all but lost hope in all honesty... Thankfully I was persistent and all is well now!

Recovery is the one which installs ota updates . Erecovery is an emergency recovery. It can help u restore ur phone to previous version by flashing full original firmware
I got it back to work....
I dloaded the rollback update.app
and then the real stock software
I think the thing that saved me was that i flashed stock recovery before having the glorious idea of relocking the bootlaoder.
So for anybody:
If ur device is not working DO NOT LOCK YOUR BOOTLOADER

yup thats the main point if you are not fully stock and soft bricked you are not advised to lock your bootloader. Once you locked your bootloader you can no more modify your system.

Locking bootloader removes root? Also more Questions. [Phone Gone Now]

I'm gifting my father in law an Honor 6X. I already unlocked the bootloader and rooted, but I'd like for him to be able to install updates when they're released. If I uninstall all the bloatware while rooted and then relock the bootloader, will root be retained? Will TWRP be removed? Will OTA updates be allowed? This is all on the stock ROM.

I believe you should be able to receive updates with the bootloader unlocked. The OTA might relock the bootloader and will most likely remove root. In order to update you will need to also have stock recovery installed so there would be no way for him to root again without unlocking the bootloader and flashing twrp.

Its also if you flashed twrp not only custom roms. You can uninstall root in the superSU app when selecting full unroot in the settings. I believe a factory reset can do it too. The next step would be to download the firmware for the phone and using fastboot to flash a boot and recovery image and then to lock the bootloader. Those steps are all in the link. That is the quickest way.

When you get into the Firmware Finder(PC) app youll notice your on a tab labeled "Main Page". Click on the tab labeled "common base" and type BLN-L24 into the search bar at the top right and then click on FIND. A list of firmware will pop up. Find the one that matches your build number and then click on the link under the "filelist" section. There will be two or three different zips you need to download. When you have the three downloaded let me know.

After that your ready to follow the steps on the other guide.
So I screwed up. Before you posted I unrooted via unSU flashable zip. Then I fastboot flashed boot and recovery to the stock one from the update.app file. Now it's got some verification error on power on and OTA updates fail. I tried moving the update.app to a dload folder on sdcard, but when it starts up it fails at 5% when restoring from the sdcard.
ETA: Tried the 360 FW which updated successfully. Booted and asked for password. After panicking shutdown and copied the HW contents to Sdcard and did the update again which succeeded. Booted and asked for password again and I panicked again. Pulled the Sdcard and booted into stock recovery. Wiped everything and then restarted crossing fingers. Started up like normal, no password request! So it looks like the phone is back on totally stock EMUI 5.0. I'll hope for the update and will try with fingers and toes crossed. Thanks for your help. I may be back, but hopefully not.
ETA2: There's no update option above the last About option in settings... How do I get the update option?

Edit: Before trying below steps. Just put the files from "BLN-L24_hw_usa"(b360) into dload folder and flash with dload. It might update the version.img without the needs for the steps below. if that brings the build number back to b360 use the hisui(PC) application to connect to the phone and update
Ok i forgot to mention something. The reason you dont have a update option is because you are on b360 which never had a button. Your build number on your phone will say b366 but thats incorrect. You cant receive an ota automatically because the phone thinks its already on the latest version. You need to take the UPDATE.APP from the "BLN-L24_hw_usa" (b360) folder and extract the VERSION.IMG file. It needs to be flashed with TWRP because fastboot wont work for some reason. That file will fix the build number and change it back to b360 so you can receive the OTA which will also restore the missing apps and features. That means you have to unlock the bootloader. Flash twrp. Flash the vendor.img with twrp and then do the dload method.
You have all the files and have done it already so this time will be easier. Ive done this way too many times with this phone. Sorry i forgot the mention the one step
Build number on my phone is already 360, and it has never been 366. Tried flashing the 360 like you said via dload and nothing seems to have changed.
Also the SIMtray eject tool seems to just go into the phone without ejecting the tray. A paperclip worked, but man this phone is really frustrating.

Wife made me box it up and ship to her dad, so I no longer have the phone. I did install the HiSuite when I first powered on the phone and it was never able to connect and see the phone, so who knows what's going on.
Thanks for all your help. I have another one, but I'm just going to sell it and be done with it. No idea what other phone I can get with the same specs for the same price that's not so difficult to flash, but I'll keep looking I guess.

Its not difficult. In order to connect to hisuite you need to enable developer settings and allow usb debugging or type hisuite in the settings search bar and click "allow HiSuite to use HDB". I got this phone for christmas and i already know a ton about it. It may seem complicated now but its really nothing.
