Problems with update 2.3.4. My phone wont turn!!!

I tell you I unlock it first, then I had problems with some widgets and I learned some new updates.
Then, I made a backup with Sony_Ericsson_Backup_and_restore.
After searching, I root my phone with "GINGERBREAK" downloaded from the internet (GingerBreak-v1.20) and finally settled "Titanium Backup" to remove some applications from my operator, then install the CLOCKWORDMOD (do not know what for) and and finally I started to flash ...
After root, flashing with FlashTool_0.2.9.1.
I suggested steps for flashing and inserted this update: "LT15i_4.0.A.2.368_Generic Global", with "wiped ...", which is to delete everything and set it to zero ..
Normal work for me ... I sent version 2.3.2 to 2.3.3 (thinking I would send to 2.3.4). It was great ... Then I appeared a notice of samsung (on phone), to install version 2.3.4 (4.0.1.A.0.283 I think it was that number) and when it started to install warned me he was going to shut down, spent 6 or 7 minutes and not lit. I tried to turn it on and vibrated, then vibrate him again and try to turn rang again, but soon ...
Then I could not turn ...
Once this happened I was like crazy trying to fix the COMPANIOM, but nothing ...
I flash again, this time with this "LT15i_4.0.2.A.0.42_ (1247-1041). Ftf" but did not recognize the flashtool as the first time coming out of the mobile code when you open the program loads and displays the model number of the phone, it did not appear.
Finally, press flash and began. (To this already, before, try reinstalling the Global LT15i_4.0.A.2.368_Generic where my computer does not recognize, nor giving flash, just not recognized out in red letters)
When flashing with the latest LT15i_4.0.2.A.0.42_ (1247-1041). Ftf, the normal flashing until the end. But my phone just did not work. The light that was on the side of my phone was green ...
I sent a technician and he said he could not ....=/
I hope you can help and serve as a case to be resolved.
Thank you very much, good luck!

did you do factory reset? I had some weird stuff going on after recovery, so I booted back to factory reset (vol + and power), after that it worked OK.
Once you requested the bootloader unlock key, your warranty might be void from that point (depends on country). The bootloader gets locked after flashing official firmware via eRecovery though.

yes i did a factory reset, still can't proceed after wi-fi+ configuration.
is there anything else i can do?

I have one question: is it possible with
-frp locked
and
-phone locked
to downgrade via eRecovery? (to b130 or something..)

I have the exact same problem.
I bought it 3 days ago, and suddenly yesterday downloaded Apps (from the Play Store) stopped working. So someone told me to hard reset it. I got into EMUI and did it. Then I rebooted it and now it stuck there. Can't complete the setup wizard.

I found no solution to my problem after reading google & xda-forum for 3 days. Tried everything... nothing worked. Sent it back and (luckily) got a new one. Now i'm more careful for sure.

The store I bought it from claimed that they had numerous similar complaints about the 3gb version. Which is the one I have. They told me I should take it back and that they will give me a new 2gb version along with any difference in money. We will see.

Exact same thing with me stuck at setup wizard so had to send it off for warranty and got a brand new phone yesterday
Sent from my HUAWEI VNS-L31 using XDA-Developers mobile app

Help please my Huawei P9 cannot proceed afta WiFi setting it is stuck on "Checking info "and Reply saying "Couldn't sign in"

The problem is Android System Webview, it's not a system app in this rom and when you reset your phone it deletes it, happened the same to me, I had to go to a huawei center, they menaged to skip the initial setup and I've installed the apk from apk mirror. Without this app the phone can't login in your google account, so if you don't install it your gapps won't work

I'm having exact problem with my mate 8 NXT-L09, after i had to factory reset when update from firmware finder failed. Anyway to bypass this problem? Do you have a way of add Android System View into the mate 8 during the bootup process. I love this mate 8 phone and 5 days now i has been torture.

Reflash the rom you were on using the "dload" method

Sorry, dont have the previous ROM, I boiught it off someone and they probably did the first update. The factory reset should reset to huawei original but i think this is where my problem sits.
HARDWARE VERSION=NEXT_L09_VN2
BOOTLOADER VERSION=NXT-C900B120_FASTBOOT
KERNEL VERSION=NXT-C900BB140_BOOT
AP VERSION=NXT-C900B140_SYSTEM
CP VERSION=21.750.08.00.010(balong)
Parameter Version:
P-00.00.000 G-17.V271.371 E-40.01.000
does anyone have an international rom for this or any version that can work.

The way i was able to factory reset was
1. going to huawei site. "consumerDOThuaweiDOTcomSLASHjmSLASHsupportSLASHdownloadsSLASHindexDOThtm"
change slash to / and dots to .
2. Select options for your phone, mine was NXT-L09. Will show "HUAWEI Mate 8 Firmware(NXT-L09, Android 6.0, EMUI 4.0, C605B100, Latin America, Channel-Others)"
3. Download, extract onto sdcard in dload folder, restart phone using vol up & vol down & power.
4. phone will complete boot restart but will then loop the boot process.
5. Do factory reset again
6. After huawei logo, different options show and you are then ok to proceed to login to your google account and setup refreshed phone.
Now on NXT-L09C900B100 build, if anyone has nougat rom for this, please share.

For future reference, if anyone gets stuck with this on P9 lite, indeed the instructions provided by Huawei point to VNS-L11C432B161, which doesn't include Android webview and therefore initial setup cannot proceed. The solution is to flash B210 on top of B161:
update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v80562/f1/full/update.zip
which allows you to pass setup as the bug has been fixed. No root/unlock/twrp required.

Recovery bricked after Nougat update?

First excuse me for opening an other thread like this, i think i have read all other threats regarding my problem, but none have the same situation
My Huawei M3 Wifi (BTV-W09) seems semi bricked after installation of Nougat Update.
The Installation (Force Install with dload) gave me an error and also while boot i got the error message: "Your device has failed verification and may not work properly."
I have the option to press "Powerbutton" and the device will boot up. I checked the Version and it showed android 7 + EMUI 5. The only problem was that almost every system app was missing, like keyboard, calendar etc. (playstore was there)
So i tried to do the rollback with:
HUAWEI MediaPad M3 8 Rollback Package%28BTV-W09 %2CC900B300%2C EMUI5.0%2BAndroid7.0 rollback to EMUI4.1%2BAndroid 6.0%29
The Installtion (force update) gets stuck at 5% and after like 3-5 minutes the tablet will boot up showing the same boot error that can be skipped with pressing powerbutton. I checked sytem and it still showed "android 7 + EMUI 5" but built : BTV-W09C900B300
I think this is the one i "need" to be able to install the "HUAWEI MediaPad M3 8 Firmware %28BTV-W09 %2CC100B006%2C EMUI4.1%2BAndroid 6.0%29"
Problem is regardless which "update.app" i try to force install will get stuck at 5% and give me same error. I have ADB/Fastboot installed and tried some different things like flashing/unbricking it with "Huawei Multitool" where you can extract like boot.img or recovery.img and try to flash it.
Also getting an error. I can access eRecovery witout problems, the option to fix it by itself by wifi doesn`t work. I can´t access "normal" recovery and i think there is the problem (may got bricked while flashing Nougat?) I think its recovery problem, cause when i boot it up to the "half-installed" Android and go into setting "hard-reset" option i know it would boot up intoi recovery and would erease everything, while bootup it shows error "reset failed".
In fastbootmode i see bootloader: unlocked FRM: unlocked
I tried to install TWRP recovery with adb but get error: adb remote command not allowed
I downloaded like 15 different Android Versions 6+7 Emui 4.1+5 to try with force update but none worked, may i have to flash special version of recovery first?
I just want a normal version of android 6 or 7 i dont mind but at the moment with half working 7 "without" systemapps its a hardtime.
I hope someone can help me.
This isnt my first android device and im not a total noob i unlocked bootloader and flashed kernels on many other phones but with the W-09 where i did nothing special i dont get why "recovery got broken"
Thanks in advance

You haven't read other threads too well: more times people reported that the bootloader got locked after an update still declaring itself unlocked!
Second thing you have not found: the Nougat update consist of 2 packages and the second must be installed from TWRP.

thanks for your anwser, i read that so i also tried unlocking it "again" and it quotet it is also unlocked in adb. I also know that there are 2 packages. That you need TWRP i didnt know thanks so i am a bit smater now. I think i ll try "relock" and unlock it again might be the right way, thanks for the tip.

This is nonsense. Unlock, install the right TWRP then install the second zip package.

i cant unlock cause i dont have the code, on the huawei page i try do make an account and get the code by providing the necessary information.
I just uploaded a picture, i choose "before EMUI5" cause this is the only option i can choose "tablets". --> i choose "tablet wifi" , enter product model "BTV-W09" then the serialnumber i can see in setting: 28D6R17316XXXXXX but then i have the problem to input product id, it say i can get it through "Dialer" app (which i dont have in wifi model ) or the calculator. Problem is in my damaged installation there is no huawei calc, other calcs from store dont work (read that problem in other threats) I tried many apps from appstore to get a product ID but huawei site keeps saying wrong product ID =/
With the program DC Unlocker i am able to see a MEID i dont know if its the right one, i tried my luck with the Product ID Generator from Huawei but it doenst work. (device not supported)

It's very strange that it says bootloader unlocked if you have never unlocked...
And was very stupid to try to installl a beta release without before unlocking and taking a backup.
Exhange your device for a Nokia 3110!

yeah at this device i never touched bootloader, i didnt think it would become such a big deal , i didnt want unlocked bootloader or other recovery just newest android. Never had any problems with the "force update function" to come back to stock. I tried DC Unlocker but cant get further cause device need to get into manufature mode (thorugh dialer or calculator which i both dont have) i hope maybe i find one more way.

Did you ever find a fix
Did you ever find a way to fix this. I'm in the same situation. I even did a VPN on my router to give me a Hong Kong address for erecovery and that still didn't work. I have the exact same product. Like you I tried to various attempts to download a new recovery, but nothing works. Nice hardware, but some of the worst software/firmware I have ever dealt with since starting with the first release of Android on the HTC Hero.

I had mostly the same problem. I rolled back to 4.1 using the rollback and the actual 4.1 update.app. I think that puts you on C100 if I remember right. Tablet I have is C128 (USA) but no problem for this step. Get the Product ID from the calculator. Allow OEM unlock in the settings, then unlock it using the unlock code. Email yourself the unlock code because who knows if their website will even be functional next time. Alternatively you can extract the stock calculator from the update_data_usa.zip or whatever and try to use DC with 5.0. That second update zip does not install properly via the dload method, so a bunch of stock apps don't get installed. You can kind of hack it and flash it via TWRP but I didn't do it that way.
Or...you can use firmware finder to force an OTA from 4.1 right up to 5.0 (350), then take that last partial OTA to 351 after as well. The way to do that is via DNS in firmware finder. Find the Full OTA in firmware finder you want, send it to the updater by changing your DNS the way it tells you to, and when it does the OTA, everything will be properly installed basically the official way. Good as new. Flash TWRP to recovery2 and replace the erecovery. Keep the stock recovery as is. Install magisk. Golden.

Also, as far as the rollback, you need to do the first one (the C900 which is just a compatibility fix to allow rollback, previously used by beta testers I believe). Then you need to do the second one, the C100. If it is getting stuck, try downloading it again and be sure you don't have anything else in the /dload directory on either internal or the sd card. I had one on both at one point so maybe that happened to you. The C900 should be very quick but the C100 will slowly progress after 5% all the way around in several minutes.
When you get to updating back to 5.0, you can choose whichever region you want as long as it is a full OTA. C128 is USA and that's what I bought so that's what I picked. That gets you back in the right OTA update channel after that.

Hi guys,
I started as a novice and have learnt the hard way.
Has anyone tried rollback to EMUI 4.1 EU version on a US device (W09) and are there any problems I should be aware of?
I have had the exact same problem shared in this thread and have gone through the pain of finding a solution. My last resort is to rollback to 4.1 and restart the whole process.
@deV14nt: you suggested that when updating back to EMUI 5.0, I can choose the region even if my EMUI4.1 is EU version. How does this work?
Thanks in advance for your help.

P9 Bricked?

Hi to all
My name is Yarli and this is my first post on XDA-Dev.
I have a Huawei P9 Lite and I have a problem.
I did root on it following one of the 1.000 manuals on XDA. I unlock it contacting Huawei, and I downloaded like 4 or 5 different roms to test.
No one worked. Never. So even having a rooted cellphone I never could use it. I did the same with a Nexus 5 before, and I'm still doing it, actually. I like testing roms. But with this P9 Lite, no ways.
This was a second cell phone to play with so once I saw was impossible to put a damn Rom on it, I surrender. And kept it on a draw.
A few months ago I read Huawei was blocking the root access on its cell phones so I did the rollback and I installed a version of emui restored and downloaded from Huawei. Everything looks like working so I kept the cellphone clean: no google account, no apps, nothing. It looked ok. Youtube working fine, camera too, everything fine.
Last week. My girlfriend broke her cellphone. "Don't worry, I have one for you". So... I didn't. As soon as you try to set your google account the Play Store freezes and went back to the "insert account" screen.
I have a Huawei Attention Center close to my place. I took my cellphone there to check it like "Sorry, I put your software, officially downloaded from your website and my phone is no working right". And they say "You have to change the mother-****ing-board. 159€". For this price ¡I would buy another brand new cellphone!
So, the question:
What can I do?
Thanks for your collaboration.
Some info
Emui 4.1.1
VNS-L31C900B170
ANDROID 6.0

I dont know if this will help but, when I enter pressing the three buttons, on the emui recovery it says "Downloading package", bla bla bla,... and then "Software install failed" The update package does not exist, please dowload the package again" and I only can Reboot system now.
What the hell to do?
Thanks

Hi Yarli,
i was wandering why you rollbacked, you could have chosen to do only unroot and
flash the stock recovery to keep having updates.
Maybe you misunderstood what happened on Huawei world.
They do not closed access to root, they closed access to website used
to request bootloader code.
During the rollback something is gone wrong and you have that firmware ( C900 ).
Maybe with a correct firmware you could solve that stucked situation.
Three buttons AKA dload is used to perform a forced update,
so you have to put a DLOAD folder in SD card with inside update.app
file extracted from FullOTA firmware.
Yep this could solve, i said could.
So if you choose to do what i'm posting here you assume all responsability
about you are doing with your device... it may simply not work or make things worse.
If you don't agree just ignore this post, if you want to try then answer my questions:
Have you already tried a factory reset ?
Wich region do you live ?

First of all: Thank you so much for your answer.
It seems I didn't get it right. At the end I wasn't using this p9 so much so I wasn't so deep on it. Now I see.
Let's see:
I have already try the factory reset, and the result is the same. The phone works, even if I put the sim card I can call and receive calls. But when I try to add my gmail account I can't. The systems gets out all the time. So no calendar, no mail, no fotos, no nothing related to my google account.
My region is Spain.
Again, thanks for your help

Hey, based on your firmware (B170) was expecting ASIA,
now i'm little confused because i can't find it for european versions.
Was your phone branded / unbranded one ? Do you remenber your last fully working firmware ?
VNS-L31CxxxBxxx ?

HUAWEI P9 LITE VNS-l31 is it possible to go from b414 to b416 with firmware finder?

Hi All,
I'm trying to update the p9 lite VNS-L31C432B414 dual sim to the latest version B416.
The phone is always officially updated, but i tryed all 3 versions from firmware finder, with the *#*# 2846579#*# *
Select Project Menu > Software upgrade > SDcard upgrade method.
But when the phone restarts it begin to update and after a little progress it failed.
The same thing happens when i try it with the firmware finder app from playstore with erecovery, or dns method.
Any help would be appreciated, thanks!

Firmware Finder
DNS/VPN method should be the best way to try this update.
The other only method that i know is to use Huawei Recovery Updater
but you should unlock the bootloader and flash a custom recovery first.
In the end it will be a bit difficult to re-lock the bootloader, never tried to do such a thing,
but you can keep it unlocked...
Good luck dude.
Cheers

Hi Dadditz,
Thank's for your response.
Last night i have tryed with a extra wifi router to change the dns number but even when the Firmware Finder app giving me the message that the B416 is registered for my phone, when booting in erecovery it installs the B414 FULL package again.
And with in the app proxy and dns method with firmware finder, the system update app from huawei gives me the sign that a update is ready to B416 with the release notes and all but when it starts it shows a checksum error or download fail.
I have registered the IMEI but do you know if it's maybe the problem with that its a dual sim so there a 2 IMEI numbers? or is the first one enough to register?
The tip for unlocking the bootloader i have searched on, but huawei has taking the unlock service down i understand, so the dc-unlocker2client program for 4 euro is the only option i think?
The main reason that i want to try the latest firmware is that people can't hear me good with this phone, i send the phone 2 times for repair and contacted the provider but the signal looks good.
Now i have factory reset the phone for the tenth time, i was thinking maybe the eset virusscanner interferes with the build in huawei/avast scanner but im not sure if that could cause it.
Thanks and have a nice day.

Hi all
I just unroot and unlock BL my phone yesterday. First i make downgrade (rollback 6.0) via dload method. Everything going very smooth and when my phone was version VNS-L31C432B160, then i'll get all newer updates via OTA (Finland), now my phone is B416

Hey dude it's like you somehow downloaded B414 firmware and putted into
the internal memory or the SD card.
Check if you have that files and delete them, then try again with the update.
Don't know about your two IMEI, you have to check by yourself wich one would work...
About unlocking the bootloader, yes it is possible with the tip you wrote (dc-unlocker).
Before attempting to do anything try first with another sim and see if is the same as now
because if nothing changes maybe it's a hardware issue...
As suggested by @oltsuboy it's possible to downgrade to MM and re-upgrade
to N android version, you only need the correct packages..
I'm here to help you...
Have a good day..
Cheers

Hi guys,
I have tryed to downgrade to android 6, and that works, and then i get OTA to B370 and then B380 so i am android 7.0 again.
But now the OTA update find nothing, it stays on B380.
Before when i checked system update with HiSuite it says B414 is the latest official firmware, but now it says B380 is??
As far as i know i used only official updates with this phone, and i have wiped partion and system a lot of times.
And mostly there where 2 sim cards in it, i only put in SD card formatted first for the update.app
So i don't think B414 is floating somewhere, but i don't understand where it went wrong.
It's a non provider linked phone with a sim only abbo from the netherlands, i already asked a new sim card from the provider to test if the voice quality improves but it makes no difference.
I'm gonna wait a little maybe a update comes, when i put the B416 update on the sd card now and do force update VL+ VL- PW. the update fails after ten procent.
Maybe tommorow im gonna look to unlock the phone for 4 euro.
Thanks for the help!
Update: I have tried the DC Unlocker program.
And obtained the bootloader code, but what do do with it now?
Something says i did something wrong, because the options where:
Read unlock codes
Read bootloader code
Lock Bootloader
Erase Huawei ID
But no unlock bootloader, so i did read bootloader and copied the code.

Hi dude,
DLOAD aka three button method won't anyway work on android 7 versions...
Sorry did you tried with your brother/sister/friend sim and seen if it's the same behaviour ? ( about the weird quality voice ).
Keep your unlocking code safe and before attempting any unlock re-try to update via Firmware Finder, checking this way...
Obviously turn on and connect with the WIFI...
After installing the app open it and add your variant (VNS-L31C432).
Find the firmware you're looking for (VNS-L31C432B416 FULLOTA-MF 2,2GB) and tap on it.
Now check the availability, register it with IMEI for the update and use the dns change / vpn method.
Once the vpn started, check repeatedly into the stock inbuild updater for a update and the B416 version should come. If will be disponible tap and download your update (should be approssimatively 2,2GB).
When it'll be at 5% pause it for a while and stop the vpn service.
Go back and re-active the download of the B416.
If all will go well you'll have the latest firmware.... :laugh:
Let me know how it went.
Cheers

Hi Dadditz,
No i don't have tryed another sim yet, the provider has said that if i give to more telephone numbers from the same provider they can do a scan for the quality.
So maybe that's something to try.
Later at night there came 3 more updates and the latest is now B414, so i am back on the same build
Yesterday i have unlocked the bootloader, with this guide: https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701
Yes sorry i couldn't wait so i think let's try
When i was at the TWRP part, when i must reboot to recovery mode it stays on the screen that the phone was not safe.
So that part i still want to proceed.
So i rebooted and go to sleep.
I just have tryed your tips, but i see the same behaviour, the download fails, the extra wifi router which i changed the dns to was not more in my network, so i tryed without it.
With my own wifi router at home, they don't allow the change of the DNS, can that be the problem? or if you put a extra wifi router to it it's no problem?
I attached some screenshots, do you see that the buildnumber is displayed 2 times after a row?
I maybe think that's because i tryed to register both the IMEI? so maybe that's a problem?
Sorry i don't know how to attach the screenshot's below.
So i put them in a album called B414 with my profile, i hope you can see them, sorry this is the first forum i post on.
Thanks a have a nice day :good:

Hey mate,
you're such as educated guy and i really apprecciate that !
Well... i saw inside your profile the B414 album and maybe i found the mistake...
damn ... seems you didn't read carefully what i wrote !!!
Look in previous post, you need the FULLOTA-MF package 2,2gb !!!
not the OTA-MF (incremental) one !!
Repeat again the procedure, register one only IMEI, hope this time
you'll be able to update correctly
Let me/other members know.. :fingers-crossed:
note: if the update will end correctly, it will re-lock the bootloader too.
Cheers

Hi Dadditz,
Thanks i didn't even finished my school so my english is not good, but i hope u understand.
I always tryed to install the full package mf B416 2.2gb but when i was testing it with the extra router it always shows a checksum error or download fail, tonight im gonna try that again, and let you know how it went and describe the steps that i tryed so maybe you can see where it goes wrong.
I also tryed the firmware finder windows version to register the IMEI, so maybe i make a mistake there.
This afternoon i was trying to attempt to proceed with the TWRP installation, but when i was booting with VL+ and power it won't go to recovery mode, on the xda forum i was reading more people with the same problem, the phone stays on booting
But the phone is working now so im glad i can whatsapp and watch netflix, so i will not try to go further with that, and focus on the B416 full update.
Thanks:good:

Can you describe maybe how i can insert screenshots in a post?
When i try to insert a image in a post it is asking for a link, can i upload pictures at XDA or do i must use another image upload server?

Dude,
sorry if i wrote something that someway hurted you,
english isn't my main language too...
Attachments aren't allowed to junior member, you need to post many times
in order to be authorized.
Let's go to the main problem...
If you want to try to flash the B416 version with the TWRP
you first need the correct TWRP version...
If you followed the link you posted above,
you tried to install the marshmallow version,
that's because it won't boot.
Your device are running android 7 ( nougat ) and you need a working recovery
in order to use Huawei Recovery Updater ( HuRu ) and flash that B416 firmware.
All files ( firmware apart ) you need are present on XDA, so just download and install
what i wrote you here.
Be sure you have installed Hisuite on your PC and it works.
Be sure you have enabled developer options then open it and
disable screen lock, enable oem-unlock and usb-debugging.
HERE to download and install Minimal ADB & Fastboot on your PC.
Connect the device to the PC, make sure PC recognize it allowing permissions if needed.
Then on the PC open a prompt (CMD) with admin rights and type "adb devices".
Below you should see your device as a serial of numbers and characters like
THIS screenshot. If that worked go next step.
Type "adb reboot bootloader" and it will reboot into fastboot/bootloader mode.
Now type "fastboot devices" and you should see your device as a serial of numbers and characters like
the screenshot i posted above except you'll see authorized/unauthorized section.
If your device are now authorized you're ready to go.
Type "fastboot reboot" and it will reboot into system.
HERE the link to download HassanMirza01's 3.1.1-1 EliteTWRP, flah it with fastboot command
( past a copy of TWRP into the adb & fastboot main folder )
( into fastboot mode ( see above ) type "fastboot fash recovery name_of_recovery_you_downloaded.img" )
When finished type "fastboot reboot recovery" or reboot with vol+ and power buttons.
Once you'll have a working TWRP installed reply me here
and i'll indicate the next steps.
note: with CMD prompt write without quotes " "
Cheers

Hi Dadditz,
No problem mate , i'm new to this phone flashing and was insecure if my english was good enough to communicate on the xda forum.:good:
I was just to let you know that my second try with the second router is maybe succesful for the B416 FULL update part.
I now connected my pc to it and when i changed the DNS i changed the second DNS to 1.2.3.4 and when the firmware app says registered to this ip:......, i took that ip in the second router.
And then boot in to huawei Erecovery and now the B416 2gb is downloading, why the DNS and PROXY in the app only provide the 700mb update all the time even if i registred the 2gb version i don't know.
Maybe the DNS or ip setting had something to do with it, my understanding of network settings is limited.
The download is 42 procent after a hour but it's a old wifirouter.
So i was now about to ask if it's succeed i could undo the TWRP and lock the bootloader and just read your message, so i don't know if it hurt's anything if i let the update install
I wait and see :good:
edit: i did see you message that the update will relock the bootloader but i was asking because i was not sure because i messed up the TWRP part. edit

The update to B416 was succesfull! :good:
I haven't see the warning that the device isn't save when booting and Netflix appears in Google Play store again, so i guess i don't have do anything more to disable TWRP and locking the bootloader
Thanks for the help Dadditz and sorry that i was impatient to wait on your message, in the future i ask and wait patiently, but hey i didn't bricked the phone
If the voice quality improves i now must test, and the next step is to ask a network scan from the provider on 2 more telephone number in my town.
Thanks :good:

I suggested, you did. :good:
All is well that ends well.
If you had TWRP recovery installed,
you wouldn't be able to update with Firmware Finder,
as you would have needed stock recovery ...
And yes now the device is 100% stock.
Thanks for your feedback dude.
All the best
