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.

3. Downloaded the firmware B019 for BTV-W09C233 (no firmware for other variants present ATM)
4. Extracted and copied update.app to SD card
5. copy to PC
6. Extract recovery.img and recovery2.img using Huawei Update Extractor

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.
EDIT
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?

I upgraded to Nougat Manually and it half worked :S

So I followed a tutorial online to install Android Nougat 7.0 on my Huawei P9 lite. Once I was in TWRP I realised I was supposed to install two update files from two different .zip files. Trouble is I only had the one update on my phone at the time. I didn't want to exit TWRP at that stage because I already installed one of the update files.
When I booted my phone after the update, it all seemed to be working with 7.0 installed. Then I noticed my internet data wasn't working outside of wifi, and my bluetooth isn't turning on. The rest seems to be running fine other than those two things.
I rely a lot on bluetooth and internet on the go. I need it back, does anyone know what I could do, outside of factory reset?
Thanks

factory reset wouldn't help, you need to reflash update.zip and data_full.zip AT SAME TIME without rebooting

Okay, I realised that just now. Trouble is I am having trouble booting into TWRP now. I just get "your device has been unlocked and can't be trusted." with an orange web link.
For some reason my phone says in the settings that I'm still on android 4.3 although the ui and functionality is 7.0. Also, the EMUI is 2.0. I don't know how I got TWRP working before but I think there's a conflict due to it half being 7.0 so recover won't boot. I have tried loads of tutorials online but none of the rocovery.img or twrp.img files are working.

have the exact same problem, on android 4.3 and stuck.
from what i understand to dload a working stock rom, you need to have the correct oem info that matches the recovery stock rom. i cant flash any OEMinfo as i cant get root from revolution recovery.
no access to Data partition either.
no other recovery's to install as its the only one for nougat.
So i need help for this issue too.

I fixed it! It was more simple than I realised. I used the dload folder method; Placing the update.app into a folder called 'dload' on an sdcard. Then holding power, both volume buttons to initiate the update.
Thanks for your help guys!!

Recovery unaviable after Nougat update

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.

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!

[SOLVED] Huawei nova bricked

I folowed this tutorial https://forum.xda-developers.com/nova-plus/development/rom-aospextended-v4-6-t3717372 and all flashing was fine. Due to some inconveniences of this new flashed rom i decided to restore to default rom. I extracted recovery and update.app version Can-L11 B396 i think from firmware finder and flased with adb this recovery. After that, it asked me to do an factory reset, i did it, but it wont boot any of huawei or Aosp Extended. The main problem i have is i can`t acces any more my phone with adb terminal, maybe after flashing the new original recovery usb debbuging reverted to un-enabled. How can I do now? Thanks in advance.

Try to flash the TWRP again with fastboot.
PS: I don't understand how you people end up like this. It never happened to me.

I cant, adb cant be connected to device. Says null operation.

finally i succeed to revert o stock rom. Now i have on About phone CAN-L11C432B397, Emui 5.0 and Android 7.0. One question please, I dont see anymore the Update system tab or something, "Actualizator" on romanian language. Is that normal? How i can check for updates?

You need to install the other zip too which has the word "data_full" at zip's name or something like that.
EDIT: @campeadore, i suggest you to edit the thread name and add "[SOLVED]" at begin and write the way you've fixed your phone (the solution), so it'll help other people who might run into the same problem as you.

I`ll do it as soon i fully resolve the problem. I followed your link and everything went fine at step 1 (Go back to EMUI 4.1 (MM). System is booting, but system update is not working. So, i want to flash EMUI 5, but can-l11c432b330 or can-l11c432b396 cant be updated, around 45% gives an error. The only version who work is can-l11c432b320 but i dont have update_full_CAN-L11_hw_eu, only the first update.zip.

Newer / newest firmware downloaded from Firmware Finder needs to be approved by Huawei and that can take some time. It's failing to install because it wasn't approved. I've read this in past somewhere.
Try B381 or B382 as i've always installed that one when i've went back to EMUI 5.

Yes, i did it now with can-l11c432b330. I think my mistake was trying to flash to EMUI5 with usb cable connected. With cable off all went fine like a charm. Now i do all approved updates with system update. Thank you so much man, really appreciated.

Seeking help: I have a smartphone huawei nova lite plus (TRT LX1) that fails to restart. It goes continuously in a loop. Entering recovery only the first 2 functions come out: wipe wash factory reset and wipe wash partition. Then using eRecovery from PC with the USB cable, proceed up to a certain point and then not continue. I think it's in soft brick. I definitely need the right software for flashing, stock roms and usb drivers. Where can I find them? Many thanks
