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.
So 5 months ago, this error happened when I tried flashing an OTA update (rather than Full OTA) through Firmware Finder when I tried upgrading from B389 to B393 on my P9 Lite 2016 (3GB Ram Model VNS-L31)
Despite this I can use my phone perfectly fine and I have been doing so with no issues since December but every time I boot I get this message in red and I have to press the power button to continue to boot.
I have never rooted or unlocked the boot loader of this phone. I am still on B389. I decided not to do anything during this time because of exams
Is there a way to fix this (ideally without having to downgrade or factory reset)
Simple Fix: Reapply the full OTA of the version your using through Firmware Finder
I've been trying to install Nougat on my P8-lite (ALICE). I started with ALE-02 B140 and following these instructions successfully upgraded it to ALE-L21 B170. Then flashed B560, followed by TWRP and finally B895. At some point in time the model number must have changed as it no longer reports ALE-L21 but hi6210sft. Despite this every thing works file. Radio and data works flawlessly too.
However when I flash any custom ROM - radio is intermittent and randomly turns off every so often for a minute or so (this includes voice, SMS and data). This makes the phone quite unusable
ROMs I tried are Android 6 (Lineage 13), Android 7 (RR, dots, AOSP) and Android 8 (RR) - and they all do the same. So I'm back on EMUI B895 - but would dearly love to get rid of it. Baseband version is 22.355.03.00.00
Any help or suggestions or questions are most welcome
Thomas.
Finally managed to fix it. Went to Settings->SIM cards->SIM1 Settings->Preferred network type and changed "GSM/WCDMA/LTE" to "GSM/WCDMA auto"
I have a huawei p8 lite ALE-L02 (alice) and im unable to upgrade to nougat . I am unable to unlock bootloader as the bootloader code website is no longer available. I will appreciate any help to upgrade to nougat.
I think you are late. Google around and have a look at https://forum.xda-developers.com/p8lite/general/unlock-code-t3830035
Well thanks anyway but my rollback keeps failing. My version is ALE-L02C190B584. The phone wont accept the rollback file. Thanks
Hello,
If there would be anybody who could help me in my problem I would be very grateful!
I was a happy nougat b.09 user when I tried to upgrade the phone to newest android, I installed Oreo B.04 and the phone got much slower, now tends to stutter on web browser and the battery life jumps like crazy. I went on for few weeks but now I can't take it anymore, I want to downgrade to Nougat, probably to B.12, but when I put either N-b.12 or N-FOTA-B10 to B12 from the download center thread into my sd card and rename it to update.zip, the phone still doesnt see it and I cant downgrade.
Is there a safe way to downgrade phone without root or risk of loosing data?
Btw. when I was upgrading the system few weeks ago i went form Nougat.b09 to nougat.b12 then oreo.b02, then unfortunately i downloaded nougatb.04 (mistaken it for oreo) and downgraded phone to it, repeated the process to get oreo.b04 - maybe this process made my phone slower? (but seems unlikely).
The accidental downgrade to N B04 is likely the big issue.
I would try flashing oreo B02, factory reset then flash the downgrade version of Nougat B12, not the regular one but this may actually be a case of needing an ADB connection or similar to reflash it with correct partitioning so I will defer to more experienced modders on this.
If you are on B04 Oreo right now, download the B12 package from a official ZTE source (ZTE Australia has the link for it). Same thing, rename to update.zip and put it in root for SD. If phone still doesn't detect, boot to recovery (power+volume up button), select the wipe/erase all data option first, select yes. After that, select Apply update from SD card then select the update.zip. package. Probably do another data and cache wipe just in case after its installed
I was going to update my P10+ (VKY-L29C626B124) to Oreo. It's unlocked and rooted, but the updater wasn't working normally.
Started with FirmwareFinder and found an early Oreo for my phone. I was going to set up the proxy download in eRecovery. In the meantime, I backed everything up and decided to pony up the 4 euros to get the unlock code again because I figure this was going to put me back in stock. After I got the code, I was going to copy my backup over to my sdcard, but there was a crash in DC Unlocker and my phone rebooted.
Now I am stuck with eRecovery trying to do something and failing all the time. I can get to fastboot, but not TWRP. I am 99.9% sure nothing was flashed (because nothing was downloaded to begin with) but it seems that eRecovery is engaged in a way that it can't be overridden.
Is there a way to get back to either TWRP or the OS so I can move my backups off the phone and try this again? I was going to flash a stock rom via the Huawei Updater on my PC and a proxy, but I am open to other suggestions. So uh... h---e---l---p ? ? ? ?
Okay I managed to push the updates through so now I am on B172. Just need to find the right build to start onto Oreo...
