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!

[GUIDE] Unlock Bootloader, Root, Install TWRP & Decrypt

For an easy way to Unlock, Root & Decrypt your Mate 8 here are the steps you need to take. This has been requested by a number of you so here it goes:
1) Unlock your bootloader. There are three steps you can take. The first is free. The second method requires you to pay a few dollars but it works and is the fastest way. I would highly recommended this method. This is confirmed working on all models.
Option 1: Make a Huawei ID on your phone and stay signed in for 14 days and go then online to unlock your bootloader and it should work on the website.
https://uniportal.huawei.com/accounts/register.do?method=toRegister
Option 2: If you want to unlock your phone immediately and don't mind paying a few dollars this method works. Visit here:
https://www.dc-unlocker.com/buy
- Download the DC Unlocker Software
- On their site buy 4 credits. I used PayPal. It cost me around $4.38 USD.
- Follow the instructions in their tutorial. Choose "Read Bootloader Code" in DC-Unlocker to get your bootloader code. It was pretty easy.
- Put your phone in bootloader mode (plug into the computer and hold in power and volume down with the phone off) and download the Android tools from the link at the end of step two. Extract them to a folder on your desktop and open a command prompt to that folder and type in fastboot oem unlock xxxxxxxxxxxxxxxx where x is your bootloader unlock code the DC Unlocker program gave you.
2) Download the TWRP recovery of the EMUI version you are currently on (5.0 ,5.1, 6.0) from here:
https://drive.google.com/drive/folders/0B5I_q70mNuR4Vmo5LUUyU2t5TWs?usp=sharing
Then put your phone into Bootloader Mode (plug phone into computer and hold in power + vol down) and fastboot flash the TWRP recovery file you downloaded. Here are the Android tools you need to fastboot flash. Extract them to a folder and put the twrp recovery img file inside the folder as well and open up a command prompt to the folder and type in fastboot flash recovery TWRP-ENG-XXX.img (where XXX is the version of TWRP you downloaded) Then type in fastboot reboot. When your phone reboots shut it back down and then hold in volume up and power until it turns on and keep holding in volume up until the phone boots into TWRP recovery.
https://drive.google.com/file/d/0B5I_q70mNuR4UzdkeERRZExnUVk/view?usp=sharing
3) Root your phone.
In TWRP flash SuperSU:
https://drive.google.com/file/d/0B5I_q70mNuR4OWlXeTJuTjdoS0k/view?usp=sharing
After flashing you will be rooted and on TWRP successfully.
4) Decrypt your internal storage.
You must decrypt your internal storage so TWRP can see it or if you want to be able to flash a rom. If you're getting an unable to format data in TWRP then you know you need to do this. Boot into TWRP then go to Wipe then Advanced Wipe then Format Data and type in yes. This will wipe and decrypt your internal storage. BACK UP YOUR INTERNAL STORAGE before you do this if you have anything important on it. (Pics are at the bottom of this post) Then either flash one of my roms or decrypted boot.img to keep the internal storage decrypted. If you boot with the stock boot.img installed it will encrypt your internal storage again and you'll have to repeat the process.
*To take an ota or do the dload method you don't have to relock"
does flashing supersu through twrp directly work? in my case i needed to flash the decrypted boot image first, otherwise id have a bootloop after rooting...

It works for me when i'm on stock B137.

I believe so. I'm not too familiar with the International firmware. I saw it posted somewhere so I saved it in case anyone needed it.
yep thats correct, B137 latest chinese and B133 latest international rom
thanks for the info, i had some problems with flashing supersu, but once i flashed the decrypted boot image my bootloop and partition mounting troubles in twrp were gone no idea what exactly was the culprit there but i guess ill stick to flashing the decrypted boot.img first before continuing with rooting a firmware...

I made it two days ago and it works with mate8.
Does this now mean we are likely to see numerous custom roms & kernels being developed in the very near future for this awesome smartphone ?
i sure hope so especially since huawei seems to have publicized its kernel source for the mate 8 just recently in the end it depends on the interest of the devs, though, and the overall popularity of the mate 8! im staying optimistic that itll be better than with the mate 7

Don't worry, it works with the Mate 8. You're doing something wrong if it didn't work.
Say we do unlock BL and then root... Than I guess we cannot get OTA updates right? Also does the BL re-lock?

You should still get ota updates if you're unlocked and rooted. Yes you can relock just make sure you fastboot flash or do the dload method to get back to stock before you relock.

Twrp for nougat

Hi everyone my device is huawei p9 lite L31 and I installed the unofficial update, after that I found out some apps are missing and the TWRP aswell so I can't flash nothing.
I would like someone to tell me which TWRP I can install and how please.
Thank you!
TWRP for Nougat doesn't support mounting of the /data partition at the moment, so there is nothing you can do about it. You should have flashed the update + data in the first place. All you can do now is unlock the bootloader, flash the oeminfo for your device and downgrade via the 3 buttons method. Next time, in TWRP for MM (which does support /data mounting), you will flash update + data for Nougat which I still can't understand nobody does.

Btw when I wanted to update I flashed both files and I think that the update wasn't complete with all files and system apps already.
Something went wrong, then. You should be able to find oeminfos in some thread here on XDA, otherwise google is your friend. Just be careful what you flash because you MUST flash the correct one for your device and locale

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.

From (Med)Rom to stockrom need some advice/guidelines

Hi!
A while ago i managed to install medrom v3 on my phone. It worked well except for the play store. I read that this is caused by a version mismatch and i could be solved by flashing certain .img files.
Life happened and i didn't use the p9 lite for a while.
At the moment i got a phone with a unlocked bootloader and i want to go full stock with a locked bootloader.
I tried several things, like rollback files, 3 button method with a update.app and so on and i keep getting the : Software Install Failed error, indicating that the versions are mismatching.
It's a EU dual sim phone and the previous version before i medrommed it was stock: VNS-L31C432B130
And hints and guidelines on what to do ?
Thanks in advance!

Simo, thanks for your reply. I checked again and it was MEDRomV2 (your work ) not V3. Sorry the misinformation.
before reading your post i flashed 161 on it through 3-button. It said software install has failed, but MEDROM dissappeared, seems to be 'stock' atm. Playstore doesn't work and bootloader is still locked tho ?
Could you give me some guidelines on (which) oeminfo (and how) to flash ? And can i revert to unrooted/(re)locked bootloader/stock rom if i follow the instruction you gave me in the quoted post?
sorry for the late reply i don't have much time lately I appreciate your effort and time.

How's the camera on Medrom v2?
Hi friends,
I managed to solve my issue.
somehow i went from Medrom to Nougat 'test-keys'. From there i installed Revolution recovery, fixed the file system format to fat and back to ext4, then i installed the beta 336 Nougat, then i Rolled back to MM B160 and from there on i did the OTA to 370 and 380.
I am running a full stock (locked bootloader) L31C432B380 Rom now. Thanks for all the input.

[GUIDE]Restoring Honor 7x (L22) back to stock for OTA (required partitions only)

This will restore your Indian variant Honor 7x back to stock, in case you have rooted or flashed TWRP before. After this you can get OTA updates and they will flash fine. If you want to manually flash OTA updates, you can continue to next video after watching this
I suggest you to watch it carefully and do same as I did to prevent any damages.

I have the files for BND-L24 uploaded and want to share same method of restore , for US version. As the method is the same.
Would it be ok to link to your thread from a new thread with L24 files attached , or add the backup here and just change the title?

All the post I see about manually flashing Oreo say you CAN NOT return to emui 5. So I would believe no
**EDIT**
I see now on firmware finder there are roll-back to emui 5.1 full-ota packages.
right now only for
BND-AL00
BND-AL10
BND-TL10
but perhaps after flashing that full ota to get partition table back , then follow this method from here to get correct regional specific parts back.
All still untested at this point
Suppose if I install Other rom first like AOSP or RR?

I have no first hand information. Just that for RR you need to first update to Oreo, so same as before, the information at this point is, NO , roll-back is not able.

What if you used recovery and went to stock but you don't have system updater and when you try to update firmware it keeps failing is there anyway to fix this on my bnd-l24?
P.S no longer have twrp
Can I try it on my Honor 7X BND-AL10 variant.??Please reply

Your other post show you are on Oreo. This method, files linked are Android nougat.
You need to replace twrp with stock recovery, then wipe cache from there. This should fix your bootloop ,caused by wipeimg cache in twrp. Unless there is more to the story than you tell.

Well it twrp is not staying on, then fastboot will have to be the method to recover
Hope this will work
fastboot format cache
fastboot format userdata
If those not work, or not allowed try
fastboot -w

the downgrade is tricky , if not done with full downgrade files. It is pretty much a half full update, then restore a backup. There are many things that could cause trouble with this.
Did you try to factory reset after failed OTA?
