(re) locking boot loader? - Huawei P9 Lite Questions & Answers

Please bear with me as this may be a biblical post
Around 3 weeks ago I bought a nice shiney new Huawei P9 Lite from CPW in the UK. Out of the box the phone was listed as VNS-L31C432B131 with EMUI 4.0 . The first thing I did was read all the various bits and bats on different threads about updating and custom roms. Then I unlocked the bootloader, installed TWRP and also rooted my phone.
I was then reading about one version of nougart so installed Meticulus TWRP in preperation to install that rom, however due to working 14 hrs a day I didnt get chance to do it being so tired.
A little while later I saw a thread on updating to B160 which would then give me the HiCare update to B370 through OS early update.
So the other day I fired up Firmware Finder and pushed the update ( via FF proxy ) to the official update app and moved from B131 to B160 with out any issue. During the " upgrade " I saw no errors or warning messages and nothing exploded so I thought all was good.
The next evening I went into HiCare and saw I could update from B160 to B370, so I did and again everything seemed to go fine. Although at the end I had no root so my Viper4Android mod wouldnt work. No biggy I though....Ill just root it again and go from there.
I then noticed I was on build version : NRD90M test-keys and I had some missing apps ie themes etc

}
Also on my app drawer the settings Icon has a red 1 on it.
Most of my phone seems to work ok but as I am missing various apps and some functions are not working I have tried to fix it. I downloaded update_data_full_VNS-L31_hw_eu.zip but I can't flash it as I have lost TWRP.
If I boot with all three buttons held I get the standard software installation failed screen, even though I have placed the above file into the root of my phone, in to a folder called " dload " and into a separate " dload " folder on my external SD card.
If I press Vol up and power, I can get my standard recovery screen with the three opions reboot, wipe data/factory reset or wipe data partition
Pressing Vol down and power achieves nothing.
No matter what I do I cant get into TWRP to try and flash the above update file to get all my apps and functionality back.
I have even tried to go back into Firmware Finder to see if there is an update package available for me but I can't get that to work either as I get a cant reach the server error.
When I try to set up the proxy it is asking me to sign into my internet connection(??)
It seems I have somehow ballsed things up in an epic way while still keeping a semi working phone. So my only option is to take the phone back to CPW and exchange it for a new phone ( hopefully already on nougart or at least B160 ) however while ever I get the warning message about my device being locked I doubt they will take it back.....
So is there a way to be able to lock the bootloader again so I can take it back?
Or could someone please help me get out of NRD90M test-keys and get everything working again with root so I can install Viper4Android again.

You should've tried searching. You can rollback to MM B160 using official Huawei guide. Make sure your update package has 3GB size, as it's the complete MM with all the apps. Then you'll be able to update to B370 through firmware finder.

you need to plugin your cable in some cases .. e.g. to enter fastboot mode.

I have tried to relock the bootloader with ADB etc however I get remote access denied errors.

Need G928V Odin Firmware with PIT file.

I tried looking everywhere but I have a Galaxy S6 Edge+ which took an OTA and got into a boot loop, nothing helps at all. I tried to ODIN Pl1 version I found but it won't get past the application optimization part with the gears before it shuts off and restarts again. I also found the PC2 version, but it won't even flash for me, that version fails, maybe because it's older than Pl1?
I just need to locate the latest file and associated PIT that I can flash on the Verizon device. I think the partitions are possibly jacked up.
I also don't want to pay an arm and a leg for the firmware.
Any help is appreciated!
I have been able to get a PF2 firmware as well, I place it in the AP area (PDA) and once connected, hit Start and the thing keeps failing, just like it did with PC2. When I do the Pl1 version though it actually goes all the way through, what gives?

What's the version that you've got by ota? Just flash that version(must be latest in case), try to boot if it doesnt; boot into stock recovery; wipe cache/dalvik, factory reset(I dont remember which options were there). The fact is; bootloaders of latest firmwares are lock up which means you can't downgrade even previous one you've been using. Custom roms would helpful to get rid of that bootloop but don't know if its available for Verizon devices. Good luck.

*Tutorial*Flash China S6 EDGE G9250 to Hong Kong firmware to get Gapps etc.

Howdy peeps i see that there's no tutorials like this here so i decided to help out fellow China s6 edge owners
So as you know G9250 China model doesn't have Gapps on it cuz china things google is spying on them i suppose here's a way to flash Hong Kong firmware on China model to get the gapps
For starters you will need 3 things
5.1.1 Firmware- Link you can risk with 6.0 firmware but i did it with 5.1.1 and worked fine didn't test 6.0 and if you're curious yes it will still work even if you have 6.0 installed i had 6.0 installed and it installed fine SO CHILL BOIZ plus if u want to downgrade to 5.1.1 this is your way to do so
Hong Kong firmware Tar file- Link
Kies for drivers mainly Link
Odin- to install this all *duh* Link
Firstly download everything *duh*
Go to this guide to unlock your bootloader XDA Link
Install KIES just to have all possible drivers installed
Then turn phone off and put it in download mode
To do that turn it off completely and press and hold Volume Down+Home+Power you will see a blue screen with load of chinese text just click volume up that's it connect the phone to your pc via USB
After that open up odin and click on pit it will show a warning just click ok and proceed select Tar file downloaded before and click ok

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then click AP and select downloaded and extracted firmware and click Start
Go watch some my little pony while it installs
After done it it will show Green PASS and boot into recovery to do *Something*
Just wait then it will restart and boot
Theres a small chance that it will show a black screen with some chinese text and 1 button wait for that button to become clickable and click it it will just do a factory reset on the phone wait up and it will reboot and after erasing via recovery it will boot in and BOOOOOM it will show setup screen so select a language and go through a setup and
CONGRATZ now u haz gapps and other google services it has plenty of languages so if you're lazy to look for english then select a random one and then go through a setup then go to settings select the language settings and then change it to English
There u go folks ur china S6 Edge became Sort of international s6 edge thanks to hong kong firmware which has all the gapps etc.
So in a nutshell this will give you
Gapps
Remove chinese bloatware like alipay baidu search etc
Make your phone usable outside of China as pretty much everyone uses google services lol

(US) Huawei Mate SE - No Oreo update option on phone

I just recently purchased 3 of these phones and 2/3 had Oreo already ready to be setup. The 3rd however only had Android 7.0 on it.
I checked under settings for a System Update option, but couldn't find anywhere on that phone a spot to check for system updates. It did however say that it was up-to-date on system patches (Jan 2018).
Huawei support recommended that we factory restore the phone; which we did but still no option to check for system updates, etc.
Any idea on how I can get this phone to update?

So you went to settings and system updates? And selected check for updates? And it shows system is up to date message?

Was phone used, or "refurbished" cause it sounds like it has been wiped out on the /data files. If there is no update app.
It was supposed to be in /data/hw_init folder somewhere.
No, no option to check for updates. What can I do to get that folder that you mentioned? Is there an 8.0 image I can download to factory restore from that?

Can confirm. Having the same issue. The system update app is also missing. Tried installing an extracted apk from another phone that was already on oreo but it failed. HiSuite can't find any updates either.
More info: Unlocked bootloader+twrp and what I thought was a "stock" rom. Any ideas?

Oreo update and DC Unlocker
I have an Honor 7X and it has caused me incredible amount of stress and waste of time trying to get Oreo. I FINALLY FIGURED IT OUT.
I had been trying to use the software updater to check for Oreo for months and it always said I had the latest software - which isn't true. I also used Hi Suite to no avail. I just registered my phone with Huawei and it updated. I am not sure if your third phone is unregistered, but make an account with them and check. I wasted so much time, bricked my phone, paid for DC Unlocker, tried to flash Oreo stock etc... finally I have it the legitimate way.
Now, the next thing I would like to do is install an Oreo custom rom - but I am not paying more money to DC Unlocker. If anyone wants me account details for the DC Unlock to recover their bricked phone, I have 2 days left and will provide info.

NRDM90 test-keys - Hopeless case?

Hello,
I have a problem with NRDM90 test-keys. I tried to update my VNS-L21 to Android 7.0, which didn't receive official updates, but I get NRDM90 test-keys. I obviously tried this guide but the Polish (I'm from Poland) version aborts at 5%. Middle East version finished update, but user data is not completed and I am with uncomplete android (no keyboard) like another users. There is no rollback package which makes my system c900b300, what I expect.
Huawei P9 lite toolkit shows that root doesn't exist as well as custom.bin and oeminfo (ss attached).
Fastboot&rescue mode says that PHONE is unlocked and FRP is unlock (both red font). I assume thats because this phone was prepared for me by guy who works with huawei phones.
Moreover when I power on the phone I get info: "Yourd device has failed verification and may not work properly" and so on. ERecovery doesn't find the software.
I tried to use sd card only with dload folder but it changes nothing.
This is dual sim version.
I didn't find more ideas how to deal with my problem, so I writing this post.
Thanks in advance!
EDIT: I tried to install TWRP via SRKToolHuawei and P9 Lite Toolkit but both operations failed like there would be locked bootloader. Any ideas?
EDIT2: Problem solved. Thread to delete.

To update or not to update...?

I see things are still fairly alive for this phone. I have a quick question about updating. I just powered my phone back on tonight after it being off for several years due to upgrades and what not. Long story short, my intent was to only use it as a means to port a Magic Jack number to Google Voice via a pay-as-you-go service.
Currently, I have a Net10 Wireless sim in the phone, and my MJ# has been ported successfully to this provider and the phone works. Of course I brain-farted and checked for software updates, and the phone successfully connected to the AT&T servers and downloaded an update (I haven't installed it though). As far as I can remember, all I did to this phone back in the day was to root it, I don't think I installed any CFW. Here's a photo of the about screen, anyone have any insight? From what I've gathered it's factory ATT firmware.
I guess my question is, do I allow the firmware update to continue? Will it even succeed if my phone is rooted? Is it even worth it to update? I may keep the phone on Net10, at least for a bit, but I may still just finish porting the number to GV and be done with it...fewer phones to carry around and all.
Thanks guys!

Do NOT update! You are on the MDB bootloader which can take advantage of the loki exploit and allow you to run TWRP custom recovery and ROMs once rooted. If you update the exploit gets patched and you are stuck with root and safe strap recovery which can boot only touch wiz ROMs. Use the towel root app to root, then follow my guide to get a custom recovery here: https://forum.xda-developers.com/galaxy-s4-att/general/how-to-one-guide-to-mdl-bootloader-t3584122
I know it says MDL bootloader, but MDB and MDL are pretty much the same. Both can use loki. If you want, you can update to MDL but don't update past that or else you'll lose the magic that is loki doki.
