Hey guys, so I hope someone can give me a hint at what I'm doing wrong. I have a Huawei P9 lite, single sim L21 version. I updated it to nougat, then installed revolution twrp, and I suppose at some time I did a wipe, or something, but anyways I have no OS on my phone.
After that, I can't get anywhere. The only options I can access are the fastboot and the revolution recovery, which would've been enough, but I can't install any ROMs. Like literally any, I can't install my old firmware, I can't install Nougat, I get errors using sideload, errors using DLOAD method from SD, not flashing system.img, boot.img etc from fastboot.
I did the rollback thing, including flashing the oeminfo in that guide. Still no solution.
Any suggestions are more than welcome, including words like "you should've known better"

lock your bootloader and make a folder called dload inside of your sd card whitin the update.app try like that.
But......be sure you flash the good frimware ortherwise you'll end up like me blackscreen,
Nope. Did not work. Not compatible. BTW, when I'm in revolution recovery it constantly says it cant mount vendor. Any ideas?
Btw thank you so much for answering!

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.
Hi guys, i updated my VNS-L31 into nougat test-key, i wanted to downgrade to stock MM because there's a lot of bugs, when i'm trying to install img file from fastboot, it always failed and i saw in my phone "Phone LOCKED" it was previously unlocked. Can anyone help my unlocking my device with
L31-900B300 build number? thanks!

Use the same unlock code you've used before, get it again.
And why are you using that build B300, you could have at leasT tried B336, which in my opinion isn't having any problems noticeable, battery drain also good...people complain about this, but if you know what you're doing this will never be an issue.

Thanks for the response, I'll try tomorrow, i've already forgotten and deleted the code. Actually, it's all misunderstanding on why i flashed this build lol. I am planning to revert to MM stock and i'm still looking for some guide on how to. I tried other methods and didn't get luck. If you have any ideas would you mind helping me again? Thanks!

Yeah I've already seen this and i'm not sure on what to download, i tried once but it says
"software install failed!"
"Incompatibility with the current version.
Please download the correct update package."
and i can't still unlock my bootloader, the website is new, and it won't redirect me to unlocking SITE from this thread LINK.
also just wondering, in this method, is it require to unlock the bootloader ? thank you so much for helping me.

This method don't require unlocked bootloader, don't require TWRP.
Just get the rollback file and full MM update file.
Install rollback first then MM file after, put the extracted update.app files In the dload folder on root of sdcard, one by one after each install
Or
If you don't want to use rollback file, unlock bootloader, then flash patched oeminfo file via:
1.fastboot using this command: fastboot flash oeminfo xxx (xxx= name of oemifo zip you have, ie. fastboot flash oeminfo C432oeminfoDual.zip)
Or
2.while In fastboot flash revolution nougat recovery, then boot into it by "vol up + power" then flash the patched oeminfo,
Then once flashed OEMINFO then install via 3 buttons mode the update.app of your firmware, this must be in dload folder on sdcard as above.if asked for password then use "reset"

I was able to revert to MM using this HUAWEI P9 Lite Firmware i don't know how, but it worked today. LOL, lastly, i just have a question to revolutionaryTWRP, i tried it once when i was having problem with ROM, and it couldn't even mount internal storage, but for other people i saw here in xda, they can even flash zip files from it. just wondering if there are other Revolutionary TWRP versions or it's all about the tutorial on using RevolutionaryTWRP? anyways, thank you so much again. and how can i tag this thread as solved by the way?

Edit title to solved.
The current TWRP by Revolution for nougat can't mount /data partition, and if you need flash anything there, you've got to change filesystem as advised In the tutorials, but you can flash mods or apps to system partition without problems....this problem is In nougat TWRP only currently, MM TWRP has no issues at all...anyways good to hear your sorted!

So i f*CKED up my p9 lite. The original os is L31C02 but a while ago i flashed the L31C432 oeminfo and im been using the B160 version since then, no problems. Yesterday flashed the L21 version of nougat, and when i wanted to come back to MM i wiped data and system with TWRP, and now i cant downgrade using the dload tutorial method ( gives me error ate 48%), tried flash nougat trought revolution recovery, gives me allways error 7. Tried pull the system.img and boot.img using fastboot but it only allows me to use files from nougat, and never boots up... Really i think i tried everything and my phone is dead ..... Any suggestions??? thank you

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

Hello fellows. I am in a deep sh&*. Maybe someone can help.
I have a p10+ L09 converted to L29, rooted, bootloader unlocked. It was on rooted stock rom. Yesterday, tried to make the update, and something went wrong. Now, I can't install any rom exept future rom or something found here. I've tried rayglobe knife, Huawei multi tool, eRecovery, dload, and no way to install an official rom. I am barely able to install twrp, format data, and install future rom before rebooting.
Tried to extract boot, cust, system from the original rom, but it says finished and bootloop just after the unlocked message. On latest versions, I cant even find them in the update.app..
Any help, any downloadable file or link is really appreciated. Please help...

What error/behaviour are you getting from erecovery?
Plop
Hello mate. Thanks for your time.
ERecovery crash everytime at 5%. If I try to download via erecovery, it doesn't download.
I've tried to extract the files from update. App, and inject them via fastboot. It goes to the end of the operation, but once rebooted, it bootloop before the Huawei logo..
I don't understand what happens.. It's like if the phone don't want the original firmware anymore..
If you have any files to propose me, I really want to try tonight...
Can you somehow recover your original oeminfo with TWRP and retry erecovery? That's how I got out of a similar situation, although I can't say for sure whether I really had the same root cause.
Hmm not sure that the oem info is ok or corrupted...
That's what I am affraid of..
I will try in a moment to see..
If it's corrupted, that means the phone is dead?
In that case you could try funkyhuawei, they provide their own oeminfo and erecovery connection. They do cost money though.
May I ask what makes you want to go away from the fromfuture ROM?
This... Android 5.1, emui 3.1
I don't know if iam becoming stupid with age, but can't find any more recent... And with the kids yelling on my back.... Lol
Well, I found a recent rom from future. Had some troubles with Android locking magisk, but now it's working ( update magisk before putting your Gmail account and restore). For now it's working fine. Just had a few freezes here and there but since this morning it's going fine. I think I'll stay with it for now.
Thanks for the people who tried to help me.
