Recovery unaviable after Nougat update - Huawei P9 Lite Questions & Answers

Hey people,
I've updated to the unofficial Nougat leak here and ever since I can't get into the recovery. The ROM is OK but no matter what I do I can't get into the recovery. After "adb reboot recovery" I just get stuck in a boot loop and I must get into the upgrade utility and restart phone into the system from there. I've tried to flash few other recovery but nothing works. So far I'm fine with the system and I'd like to also try LineageOS but I have no way to flash the ROM. I have tried "Fastboot flash zip xx.zip" from the bootloader to flash LineageOS but it told me I don't have permissions so it was no good.
So do you folks here have any idea what I did wrong and how to make the recovery work again? I'm kind of learn from the tutorial guy so I'll post the sources I've been using to do the flash.
Unlocking bootloader and flashing new recovery
I've only used the unlock bootloader and flash twrp sections with their provided recovery. I've also tried to flash THIS recovery by Meticulus after the nougat update.
Flashing the ROM + used ROM
Used the old process because upgrade with system utility kept giving me errors.
Model number - VNS-L21
Also if this issue can't be (yet) fixed do you know any way to safely flash ROMs without recovery?
Thanks for any kind of help

You cannot flash any ROM in the nougat recovery, because it does not support /data mounting. Downgrade to MM and install the ROM you want from there.

@SALVO9
Ok, thank you for the reply. I'll probably try to downgrade and flash it afterwards to know which ROM suits me better. All I need to do is find the stock ROM copy it to the phone and restart with all buttons pushed right? Also, do you have any info about when there will be a nougat recovery that can mount /data?

No.
Flash proper OEMinfo first!

@Schlengge
Thanks for the advice. I did my research because I didn't know a thing about oeminfo and I have hit a wall since my phone is not rooted(Should have mentioned that earlier I know) and I'm supposed to replace custom.bin and then flash the img. So afterwards I searched how to root this nougat ROM and found nothing no app was working and everything I found was just using the phone's recovery which I can't access. Does anything come to mind? I will continue getting through the pages of google but I don't think I'll find anything useful.
EDIT> After some searching I found the official rollback package. I have yet to test it (downloading on slow connection atm) and I hope it will work.

Ok it's finally done and I'm back at old stock ROM(EMUI 4.1.1 VNS-L21C432B160) after hours of searching I gave up on the oeminfo or rooting the phone. I searched for the stock firmware and found some rollback packages on the Huawei site. I will post the links in there you even have instructions packed with the zip.
LINK1
LINK2
Download both start with the smaller one because it's flashing first and follow the instructions in the pdf. Worked for me so hope it also helps you.
Also as I found out just now this rollback also locks back your bootloader so be sure to unlock it back again with the code.

Stock recovery extraced from BTV-W09C233B019 ROM - untested

Hi M3 users,
I'm a long time lurker and reader on XDA. Now it's time to give something back or at least participate
Following my recent M3 purchase a dugg a bit deeper into this topic and tried to get us the stock recovery for our devices.
I'm not really a dev. I just used the information I found here and in the russian forum where greatslon (thank you guy) is posting his work.
If you find an error in the process please let me know. The files have not been tested in any way. I have no idea if this would even work (encryption and so on).
So I managed to extract the recovery.img file from the chinese rom. This method will also work for the LTE variant.
Maybe @greatslon or @somboons can share their view on the topic or maybe @somboons can even use it in his tool.

Don't quite understand what's this for. First of all, recovery should be the same version as your ROM. I don't know if their mismatch will immediately lead to some malfunction, but some people on 4pda said they should match. Second - stock recovery's functions are limited to factory reset (wiping data, cache, etc.) and installing OTA updates. Without changing OEMINFO (and it's still unconfirmed), you won't be able to install any OTA except those, intented for your model and region, so again there's no need to install a higher version of recovery than your ROM is. But anyway, thank you for the extraction instruction.
P.S. I think there's no need to flash both recovery and recovery2. Recovery2 can be successfully replaced with TWRP and this combination is really great, cause you can launch TWRP by holding Volume Up button only.
And the only reason why you should keep recovery original is that it doesn't really wipe /data - it also creates some files there like custom.bin, containing your regional settings.
Hi Slavon,
Thanks for your highly appreciated comment. @somboons was looking for a stock recovery so I thought this might help.
Your given information are really helpful. I did not know that you could flash TWRP in recovery2 and replace erecovery Handy information.
I'm pretty new to the Huawei structure so always glad to learn something.

A lot of good information can be found here: http://forum.xda-developers.com/honor-7/general/dual-recovery-honor-7-t3308398

Giving Back
Benjamin,
I've also been a long time XDA lurker. Most of the devices I have owned were mainstream and thus already had a very active XDA developer community; Even if root had yet to be achieved, there would be hundreds of messages on the topic.
It seems the Mediapad M3 is just getting started. I am a developer of over 20 years, but very little android experience. However, I have recently spent a considerable amount of time (about 50-100 hours) working with the low level ADB protocol source code. And I have rooted and flashed no less than 50 devices, everything from cell phones to Android TV devices to routers.
I'm going to take this device on as my first real dev effort in this arena.
I have a few goals:
1. Get working backups for people that soft-brick or need to revert (including myself).
2. Recompile TWRP for the M3 to confirm greatslon's work, and better understand the process.
3. Release a stock rom that's pre-rooted and cleaned up (not that there was a lot of bloat on my device).
4. Release a custom rom that's not MIUI (perhaps based of CyanogenMod).
Since I have virtually no experience, I am sure these goals are quite lofty and will take some time. But hey, you got to have a plan, and I don't have anything else to work on right now.
Let me know if you want to work on anything together, or if you need any help with anything development related.

Hey hey 0D0A,
I totally agree with you regarding the backups, I think once the first OTA update is pushed for the EU and US devices we have a good and safe way to go back.
Especially the US owners are struggling with greatslons TWRP version, that's the first thing we should tackle after the backup topic is cleared
I will contact you regarding possible work
Best regards,
Benjamin
can flash twrp via fastboot but get error saying and no recovery
hi, first thanks greatslon for doing the work on m3.
i seem to have succeeded in getting stuck and can't get it to boot into your custom twrp. adb on linux was working fine, but no longer. ditto for fastboot just get "waiting for devices" now. i switched to win10 and installed the hisuite app so i can use fastboot but still no adb. so i have tried to flash recovery and recovery2 but when i try to boot recovery i get error "Func NO: 11 (recovery image) ERROR NO: 2 (load failed)."
i then downloaded your custom rom and tried to flash the boot for that still no luck. i can't use adb so i am not sure how to just flash the custom rom with fastboot without being able to get into any recovery.
i did have this all rooted and working with your twrp but kept having issues with dpi and there was an ota update (b003) which wouldn't apply. so i tried to restore backup and it wen't south from there. basically now can't do much other than see the unlock "can't be trusted" page and bootloader.
any suggestions?
Desperately need stock recovery img, not sure exactly what when wrong, but it is stuck in a horrible boot loop. Tried Benjamin's recovery files and they seem to remove twrp and put it somewhat back to normal, but can only access the emui recovery and that fails to load the files. Put twrp back and tried greatslon's ROMs, they load but goes back to boot loop. Wipe and format everything, install my original backup through twrp recovery, it says it works, but again, back to boot loop... at this point I think I'm dead... any ideas, any word on the official recovery img? anything? Help!!
What device do you have? And what version were you on?

Hello, I am unlocked, TWRPed, and rooted, but am trying to reverse all of that. My build number is BTV-W09C128B002. Is it safe to download the stock recovery from the OP for my device? Or do I really need the C128 version?
Hello and sorry for the late response, you would need the matching version for your C128 device.
I may be able to extract recovery from an update, I have to look into this tomorrow.

Thanks! I have been able to use the Huawei Extractor to extract a recovery.img from OTA updates, but have been afraid to try flashing it. It has been recommended to hold off on trying that since that recovery.img is from an OTA and not a FULL update. Any thoughts?

Having problem rooting my Axon 7 A2017U

Hey guys, first of all sorry about my english, im french.
So my problem is: I tried rooting my Axon 7 A2017U many times, with different guides. I always end up with a softbricked phone, having to restore to stock using MiFlash.
My bootloader is unlocked, i have stock recovery and stock rom for now.
Whenever i flash TWRP, either the signed one (from @tenfar) or unsigned (and up to date) ones, i can't go past the menu saying something like "your phone cant be checked for corruption, please lock your phone [...]" it just freeze. i did read somewhere that i should flash chainfire's root or a special .zip that, i guess, disabled some check that could prevent booting a phone with unsigned stuff/edited system (after flashing TWRP, so it could boot) that didn't work out. i think i found that information in some LineageOS thread here on XDA.
My ultimate goal would be to get a rooted stock nougat 7.1.1, up to date TWRP recovery and to be able to switch to LineageOS to try it out soon.
For what it is worth, i rooted many phones over the years, so while i'm no expert, i should be able to follow most of the steps you give me.
Thanks alot!

Okay. Download and flash this one alone via fastboot and see what happens. This is one the I personally use. It is required for any of the newer versions to work properly.
twrp-3.0.2-2-a2017u.img
You can choose to rename it to just recovery.img, then:
1. fastboot flash recovery recovery.img
or
2.
if you choose to work with the same filename:
fastboot flash recovery twrp-3.0.2-2-a2017u.img
Select reboot to recovery from the bootloader menu now and try again.
Either way, should work fine. I know you mentioned you knew the basics, but just want to be sure.
Also forgot to mention. If TWRP works but you still can't get your phone to boot, you need to follow this guide here
You can start from the part that says:
-----------------------------------------------------
UPDATING FROM B20_Boot / B20 / B27 / B29 / B15(N)
-----------------------------------------------------
Again, that's the ROM I personally use if I want to go back to stock, not the one from the ZTE site.
Gonna try it and give feedback. thanks for taking time to help!
edit: im downloading the rom from the link you shared.
like you said, i can get TWRP to boot but not the phone.
So if i use full stock from ZTE, it can't boot with modified recovery?
edit 2: i don't know what worked, i think it might be the bootstack. or the rom by DrakenFX. now i can boot to the rom with a TWRP recovery installed. It worked, but i soft bricked again trying to flash SuperSU. So now i'm retrying with an updated TWRP.
I haven't tried that yet, but I really suspect that's the reason you're having problems. I rarely use pure stock ROMs. Like you, I'm not an expert in Android Development so I can't tell you why. Just been a flashaholic for years so made a few observations.
Which supersu are you installing? If you're swiping to the right in twrp, you need to install the dm-verity zip or supersu 2.79. There's some issues with newer builds.
Everything is working like a charm! Now im going to finally give lineageOS a try
I used Chainfire's SuperSU 2.79 stable.
Edit : Everything is working flawlessly! I'm running the lastest LineageOS nightly with root (Chainfire's 2.79). Followed their instruction and installation was smooth as butter. I should also point out i flashed the lastest official TWRP which seems more stable than the one @KwesiJnr suggested. The one he suggested was giving me some "can't read X partition" in red text everywhere in the log section, which the official one doesn't do. It was doing his job properly anyway though.
I can't thank @KwesiJnr enough, it helped me find the single mistake i was making.

Yeah, like I mentioned before that was the base TWRP you needed to flash first, before any of the newer ones. You weren't intended to use it indefinitely.
There's a lot of Dev love for our device now and support is growing ... exciting new ROMs cropping up. Don't hesitate to try them out.

HUAWEI P9 LITE NRD90M(test-keys) TO MM HELP Urgent

Plzzz help im stuck I want to rollback my huawei p9 lite VNS-L31 where its build number is NRD90M(test keys) to marshmallow 6.0 help don't know what to do . Plz if you can explain step by step what can i do because i'm not good in these things , My bluetooth not workng , there no calculator , no software updater , i am not able to check if got update or not and so on......, im stuck plz help
Well hey.. first download this rollback package from this link:
http://download-c1.huawei.com/download/downloadCenter?downloadId=93645&version=371484&siteCode=np
Extract and move all the files to dload folder on your external SD Card then install it with the 3 button method. If there's no dload folder then create one.
So the phone will reboot and now you can downgrade to any mm rom
Now just download this mm rom from this link:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66015/f1/full/update.zip
And again extract and move the files to dload folder on your sd card.. Install with 3 button method.
Done! Everything should work now!
In case If you don't know what the 3 button method is..lol
•Power the phone off ?
•Just press and hold on POWER + VOLUME UP + VOLUME DOWN buttons
The phone will start installing the rom and that's the 3 button method ?❤
this is not working for me. it says incompatibility with current version and to download the correct version.

Man, you have to do entire procedure: unlock bootloader, install twrp for Nougat and flash oeminfo for your phone. Before that you have to put in dload folder MM firmware (B130/B131),
because after flashing oeminfo phone try to repair firmware from dload folder. If repair do not start, power off phone and power on with 3 keys combination.
Hi All,
I'm having a similar issue as lennie27 however I think I might have strayed down an incorrect path during the process of upgrading to Nougat. My device shipped with VNS-L31C16B120 with no updates available through the stock updater. I tried the Firmware Finder guides which listed options for VNS-L31C169B13x and VNS-L31C432B13x however none of these updates would work, updater would say it's incompatible with current version. I also tried manually downloading the VNS-L31C432B160 firmware and installing that with the 3 button method as well as the EngineerMenu option with the same result (found guides that stated needing to be on B160 or B161 before making the jump to Nougat). Eventually I decided to unlock the bootloader and install Nougat through TWRP and followed the obeygeekupdate-huawei-p9-lite-to-android-7-0-nougat-manually guide (can't post links ) on manually installing Nougat (stupidly never paying attention to the fact that it's a beta build guide). I've installed TWRP to the device again using the P9 Lite Toolkit v0.0.0.11 found here on XDA (used this when on MM however the upgrade seemed to restore the stock recovery) with the idea of downloading the build from the ministryofsolutions huawei-p9-lite-vns-l31-nougat-b371-update-stable-europe page and pushing that to the device instead (however now the device doesn't want to boot into recovery)
Now my only concern is, will this work? I've noticed a bit of commenting going back and forth on the ministryofsolutions site which essentially boiled down to the need for debranding the phone (apparently C19 is MTN South Africa specific and I need to debrand it and get it onto C432 Europe before mucking about with Nougat, but alas to late) which seemed to be something I should have done while on MM still. If I can find a full firmware link for VNS-L31C16B120 can I flash that through TWRP without needing to follow any prerequisite steps? So far nothing that I've tried to flash using the three button method has worked, I'd just like to get back onto an official stable firmware again.
Any advice will be appreciated

you need to install nougat recovery, not the one from the toolkit. then twrp will work and the device will boot.
to go back to 120 you need to install oeminfo, and then the update.app

Thank you for the reply, managed to come right a few hours after posting. Turned out the copy of TWRP that I had on hand was more outdated than I thought, downloaded the newest copy and that worked on the device. Additionally I managed to find a website listing just about every firmware for the phone (Including my original MTN ZA specific variant) so I downloaded that and managed to restore the phone using the three button method. Phone is back to stock now and even the unlocked bootloader nag screen is gone so I'm guessing the bootloader is locked again as well One day when I'm brave enough to attempt this again I'll look at debranding the phone and getting it onto a C432 based ROM before getting it onto Nougat again.
phone bricked
hello guys! im currently on lineage os 14.1 by meticulus, i wanna revert back to stock mm but i cant. i flashed the custom rom from mm using twrp recovery by meticulus, but now i cant even boot into erecovery! can you pls help me!:crying: DLOAD method doesnt work!

How to unbrick my ZTE Axon 7 mini b2017g

Dear Seniors.
I am facing great hardship because my phone is stuck at boot logo.
No booting in recovery mode to flash another rom.
I did unlock bootloader of it by using tuliptool with success. After that i flashed custom rom in it. after reboot it is happening that.
Please suggest to recover it.
Did you flash twrp after unlocking? Did you make backup of stock ROM? Perhaps find a version of the factory firmware and flash that.
Dear I have no backup and i flashed TWRP recovery.......
It is to aware you that i did relock bootloader now my phone is working properly. but i am unable to enter recovery mode. !!!
Now my phone is running android 6.0.1 B02
But i am failed to root this rom uptill now due above mentioned problem.

In easy words......... my recovery.img has been corrupted. I have no idea to get rid of this situation.
I planned to unlock my Mini's bootloader this weekend. After reading this post, I decided to act later until the root cause has been figured out.

Several people myself included have been able to use tuliptool to successfully unlock and root the device.
mine is hard bricked too. but I think it is worse than the case listed on the op.
if you want to hard bricked these are the steps:
follow the procedure to install the Spanish ROM 6.1, than another android m b12, than finally the android seven......use tulip tool and install twpr fine, root ect. amazing ROM.......buuuuut......I lost my IMEI somewhere in this process, and the original FTM which had a small menu changes to another static one, without the menu.
I needed this menu to open the com port to fix the IMEI. than I had the brilliant idea to re-flash android M via twrp (without modifying the zip file to remove the recovery, something I knew so well from the older axon mini).
results:
-lost twpr because the stock ROM wrote over it,
-cannot boot the OS because I flashed android m but the phone had the aboot 7.
-i now have a brick
I need a genious to sujest something to bring it back to life........sh....t...sh...t.....sh...t
any chances I could inject aboot7 via ADB through my dead recovery which somehow the phone recognises? ADB shell still seems to be working
thanks

P8Lite stuck on huawei logo - had access to TWRP

Hello, it is my first post on this forum and it of course has to be problem. I am not expert in mobile phone hacking/flashing and this issue is too big for me to handle.
So like 6 hours ago i had working p8lite L21 with official android 6.0 and locked bootloader. I really wanted install costum rom due to performance issue, so i downgrade it back to 5.0 lolipop, than I root it with kingroot and successful extract key and unlock it using this tutorial: https://forum.xda-developers.com/newthread.php?do=newthread&f=4627
Than I flash recovery and install TWRP 3.0.2-0 and it all just worked. I was so happy that i manage to pull this off and I forgot that now i have EMUI 3.1 (ALE-L21C432B170) and i flashed phone with this:
https://forum.xda-developers.com/p8lite/development/rom-lineageos-14-1-p8-lite-t3824247
Of course it bricked because I missed that part with special version of TWRP. After that i tried to install something older just to get phone to work again:
https://forum.xda-developers.com/p8lite/development/rom-cyanogenmod-13-0-ale-l21-t3708835
And surprise, surprise, it did not work either and now I am stuck with huawei boot logo.
I did some research how to fix this issue, but i found so many different problems and solutions, I thought that at this point I really should ask for help because I just have no idea what i am doing now At this stage, can i just flash some costum rom (idc what exactly, just wanna to be lightweight) or i have to somehow restore original firmware? And if so how to do it? As i mentioned, i had access to TWRP.
Thanks a lot for your help in advance.
can someone help me with unbricking this phone? ?
@edit ok nevermind, i thought that this phone is cheap anyways so why not risk and just flashed boot/recovery/system from stock rom with fastboot. I did it and it works again, i needed just this simple hint to do it but i guess p8lite forum is dead.

Than I flash recovery and install TWRP 3.0.2-0 and it all just worked. I was so happy that i manage to pull this off and I forgot that now i have EMUI 3.1 (ALE-L21C432B170) and i flashed phone with this:
https://forum.xda-developers.com/p8lite/development/rom-lineageos-14-1-p8-lite-t3824247
Of course it bricked because I missed that part with special version of TWRP. After that i tried to install something older just to get phone to work again:
https://forum.xda-developers.com/p8lite/development/rom-cyanogenmod-13-0-ale-l21-t3708835
And surprise, surprise, it did not work either and now I am stuck with huawei boot logo.
I did some research how to fix this issue, but i found so many different problems and solutions, I thought that at this point I really should ask for help because I just have no idea what i am doing now At this stage, can i just flash some costum rom (idc what exactly, just wanna to be lightweight) or i have to somehow restore original firmware? And if so how to do it? As i mentioned, i had access to TWRP.
Thanks a lot for your help in advance.

Can you access TWRP or fastboot mode?? Yes, the thread has been quite inactive... it used to be totally different few years back...

I believe I can help you... Check the First Comment of that post... you'll see two additional firmwares... Only those firmwares have EMUI 4.1... b896 is for dual sim and b895 is for single sim... use any of those as per your requirements... after that download the LineageOS firmware and then proceed as per the Thread's recommended way... Also, before installing LineageOS, make sure you don't have any lockscreen lock...
feel free to ask if you have any more questions...
PS: i may reply bit late... maybe an hour, 5 hours or even days... but will try to check frequently..

No worries, im happy that someone reply to me
So yea, i noticed those two softwares, i have two imei number so i picked b896 version for dual sim, but when i extract it and place in dload folder and try to update it via holding power button + -, i get software installation failed message. So I am not rly sure how to install this firmware, do i have to extract update.app and flash recovery/boot/system with fastboot, or i need to install it using some twrp? I look for guide but everyone are using this powerbutt + - methode to do this

Do you mean Vol +, Vol - and Power Button by powerbutton +- ? That's one way of flashing it, if you get error by that method, try it once again. If it doesn't work at all, then yes extract the update.app and go for the hard way...

Yea, i mean that i holding all three buttons (power vol+ vol-) and than it just says that installation failed. To flash it with fastboot i need to just flash recovery/boot/system or more files? I am asking because currently i have android 5 and this firmware is android 7 and I am just not sure if i can just simply flash those files and it will works.
Thanks for helping me

Which one are you trying to flash??? b896?? or simply LineageOS??
If it's b896, then I did read that it can only be flashed on ALE-L21C02xxx, but i am unsure about it... I did installed LineageOS and Resurrection Remix back in the days but I don't think I ever used C02 ROM for B896...
Also if you have the latest TWRP, you can simply flash with it... Try it...
Here's the link for tutorial
