Help finding B370 stock rom to extract stock recovery - Huawei P8 Questions & Answers

Hey all,
I need to flash the stock recovery over the TWRP of my unrooted P8 GRA-L09, to update EMUI from 4.0.1 before rerooting. I understand that I need to extract the recovery from the stock firmware with Huawei Extractor before flashing it from fastboot, but I couldn't find the B370 rom anywhere, neither on these forums nor elsewhere. Any ideas?
Thanks!

Sorry for ****posting, my question has become the following (since I eventually found this EMUI 4.0 B370, but): Can I flash a stock recovery extracted from an EMUI 4.0 over a TWRP 4.0.1 without screwing it up? Thanks!

yes you can, just extract RECOVERY.img and flash it over TWRP, its normal approach to get stock

From Lineage Os 13 to Emui

Hello everyone !
I'd like to know the way to go back to Emui, 4.1 or 5.0, after a installation of Lineage Os on my device, a CAN-L01.
Can anybody help me and the people that installed Los and want to go back to Emui too ?
Thanks

How Did you installed LineageOs with fastboot or twrp and did you ever flashed nougat firmware?
You can flash stock firmware via fastboot you need to install on your pc firmware finder, huawei extract tool, fastboot and hisuite (for sub drivers).
So - open firmware finder and search fwd for can-l01 download it and extract update.app
- run huawei extract tool,open update.app with it and extract (with right click) boot.img, cust.img, recovery.img, system.img and userdata.img (cust.img and userdata.img are just in Marshmallow for nougat rom you only need to flash boot, recovery and system) in the root of fastboot folder
- run fastboot trough cmd and flash images you have extracted with huawei extract tool.
If you never flashed nougat you can flash marshmallows, in firmware finder marshmallow firmware is somewhere about 1.9gb.

Or you can try the other method, download fwd with firmware finder, extract update.app, extract with huawei extract tool recovery.img, flash recovery with fastboot, create a new folder in the root of your ad-card and name it dload, copy the update.app in dload folder, open the dialer app and type
Thanks for your fast reply !
I installed Los with TWRP.
In fact, I have tried for a week to install Emui 5.0, I flashed again and again changing my method but the best result I got was a bootloop, so I went back to Los. I did a full backup of my system running onto Emui 4.1 but to perform something like this I had to remove encryption from my /data partition, I did it with the command fastboot erase userdata. However, everytime I was booting the rom it encrypted the /data... So my backup doesn't contain /data and I think it is the reason I havn't been able to go back onto Emui so far.
Could you provide me a link to download a fullota of any Emui 4.1 firmwarefor CAN-L01C432 or C109 ? I already looked for it but I can't find anything.

Can you upload your backup? I was looking for Can-l01 marshmallow backup.
I can upload my backup if you want, but this is a CAN-L01C109, France version.
I'll share the link when I finish downloading the C432B100 and uploading my own.

B371 boot.img and recovery.img

Guys, I need some help. I need to flash the stock kernel and recovery in order to update OTA to b381 (when I try to install it it goes into Revolution Recovery and the installation fails), but I can't find it anywhere... I tried to flash the ones in the b381 update but I had problems unlocking the phone since the code was not recognised, and had to bypass it with adb. Now I'm back to Revolution Recovery and Elite Kernel V4, what could have been the problem? The kernel or the recovery? Anyway, could anyone give me a link to the b371 stock boot.img and recovery.img? My internet connection sucks and I can't dowload the whole firmware to extract the images (I probably deleted the backups I had made before changing recovery and kernel, yes, I'm dumb).

Is it possible to update to B381 (via OTA update) having a custom recovery?

Hi all,
I currently have a P9 Lite with VNS-L31C432B371 firmware installed.
Recently, I received the VNS-L31C432B381 update via OTA. Unfortunately, when the phone reboots into recovery mode, the update does not even start; instead, I get redirected to the custom recovery (TWRP 3.1.0.-2, system partition read-only) "homescreen".
Is there a way to update to B381 without wiping the entire phone?
Thank you for your time.
The OTA update system uses the EMUI stock recovery so no, there is no way you can update your phone through the updater by using the custom recovery

Ok, thank you!
Another question: is there a way to obtain the stock EMUI recovery and flash it to execute the update?

Yes.
Download your build's update.zip, extract the zip to desktop, you'll then have an update.app (you probably need the full ~2GB build, not OTA, e.g I use B370);
Extract recovery.img from the update.app via HuaweiUpdateExtractor;
boot to bootloader;
fastboot flash recovery recovery.img.
Done.

Thank you!
I succeeded in extracting and installing the recovery from the update.zip. Unfortunately the OTA failed anyway.
At this point, I think I should just wipe the phone and install the complete update from here.

Well I , like you, had a custom recovery. The 3-button method didn't work for me and even after restoring the stock recovery I was unable to install the update.
I unpacked the Update.APP file and flashed through fastboot the BOOT, RECOVERY, VENDOR and SYSTEM .img files and I was succesful but now I have the Model number as generic_a15 and Build number NRD90M test-keys. I can only assume some of the other img files carry the information about my phone. At the moment is stable enough but I can't open the Security menu.
If someone has any idea on how to flash the other img files, please let me know

I only have old oeminfo.img packages, do you know how I can build one? There is a PRODUCT.img but it is considerably bigger than the oeminfo package that I have seen.
I flashed all the old B370 files, update.zip and update...hw_eu.zip, with DC Phoneix (a non free tool but saved me from.a bricked phone). After that, I flashed the new package and got the Security settings and Developer Options to work again.

[resolved]Unable to flash anything other than twrp

EDITED: Partially resolved... I recovered but now i am stuck on an emui 3.1 with no gsm working. I have a single sim Huawei p8 lite(ALE-L21) the IMEI is unknown baseband version is empty and model name which is supposed to be ALE-L21 is hi6210sft. Build number is also strange: BalongV100R001C50B311. I would like to know if there is any other way to return to a fully functional emui 4.0 and android 6.0 with GSM working(1 sim). Things i've tried: Checking for updates within EMUI updater.
I have a small little problem... I am quite a huawei newb as Samsung rooting was relatively easy.... One day I looked up on google how to root my personal phone Huawei P8 Lite (ALE-L21) with a Vodafone boot up animation but something went wrong.
I downloaded a "rooting kit" with a .bat file specifically for an ALE-L21 but after going through the whole process (boot loader definitely unlocked) and now nothing works except fastboot mode and recovery mode (twrp) when I try to boot up the phone it gives me an error about an unsuccesful boot and system flash while taking me to the rescue mode(very similar to the fastboot mode) I tried to restore the firmware (I do not know if it has to be same version as build number)... via stock recovery and and update.app but the circle kept being stuck at 90%. I also tried to split the update.app file into a boot.img,recovery.img and system.img but sometimes only system.img or boot.img is outputted with the split_updata.pl. When i try to flash something else other than twrp via fastboot it gives me an error saying "FAILED (remote: Command not allowed)"
I would like to know of a 100% efficient way of restoring or reflashing the full stock emui 4.0 android 6.0 firmware including root although a stock rom is preferred.
Thanks

Your baseband version is empty because the phone still got a MM modem on it, if the TWRP is the only thing you can flash right now try to find a custom EMUI 4.0 ROM for your device (P8 lite) if I'm correct? and try to flash it, after that go back to TWRP and do a factory reset. After that try to fastboot flash boot.img recovery.img abd system.img, if you want bloatware flash cust.img as well. Hope this helps a bit!

Arent the boot.img, recovery.img and system.img the actual rom? if not what format should roms be in? Please note that not all custom roms for customizing the emui 4.0 are supported from emui 3.1. Some links would be really appreciated... so much spam on the internet! I am also worried about trying roms that are made for emui 4.0 and say that the emui 4.0 already installed is a prequisite. Should I?

Aren't you on marshmallow before you downgraded to lollipop? If you were, modem of MM is not compatible with lollipop hence IMEI and baseband are empty now for you. Search for EMUI custom ROM's to flash thru TWRP (not CyanogenMod). Also, you're in a wrong forum because this is P8 strictly, here are threads for your phone: https://forum.xda-developers.com/p8lite :good:

Thanks I tried what you said in your previous reply but another problem came. I installed an android 7.1.1 custom rom but now GSM doesn't work. SIM card would already be in the tray in the phone but it is not detected. Why would I need a phone which isn't a phone? Now i'll post another issue on the proper thread. The android worked fine. I don't know if anybody knows of a huawei emergency software recovery as samsung does... HiSuite only has 4 devices available for emergency software recovery. Also original links on huawei website have disappeared and huawei links for stock rom on xda are also temporarily removed.

I told you to flash custom EMUI rom, not CyanogenMod. Now u need to fastboot flash the stock firmware, after that do a factory reset to get your sim functionality back.
Thanks anyway... I resolved this by flashing an emui 4 based custom ROM and I got SIM back plus root(kangvip). Also did a nandroid backup now that everything works good. Btw I never flashed Cyanogen mod ?.
Not sure if it's worth it to go back to stock now...

well, you said "I installed an android 7.1.1 custom" having in mind 7.1.1 is basically cyanogenmod/RessurectionRemix/OpenKirin... those are not official. And yeah, that rom that you're on right now is also official but with some tweaks/optimisations/modifications so you dont have to worry

OREO original recovery

Does someone have the original recovery for OREO?
I have TWRP and Magisk Installed and cannot install OTA or FULL-OTA with twrp.
I need the stock recovery for OREO.
I would appreciate if someone can share it.
eRecovery doesn't work for me and I don't want to format the device again (I already bricked it once and don't want to play with HWOTA - testpoint method was needed to get it back to life)
I've extracted the recovery myself
Here is a link for the stock recovery extracted from VKY-L29 8.0.0.365 firmware (for the C432) variant):
http://www.mediafire.com/file/dy4m97771qz6m7z/RECOVERY_RAMDISKB365.img
You can flash the .img file using TWRP (flash it over the recovery partition) - not tested with fastboot.
I was able to update to the last version using the FULL-OTA-PV file and my bootloader is still unlocked, then I flashed twrp, installed magisk and then again flashed the stock recovery for future updates.
USE AT YOUR OWN RISK!!!

It should work.
Do not use firmware extractor without creating a map for your device.... or you may brick it. The correct partition is recovery_ramdisk
