OTA failed with BootLoader locked/Stock Recovery !?

Hi Guys, I need some help
I am on MT-LV09xxxB137SP03/KitKat 4.4.2/EMUI 3.0 build. Recently I got a notification about an intermediate update before LolliPop: xxxB145: so I tried a OTA update which failed (no specific error, just "software update failed"). I downloaded manually the update, put that in the dload folder and tried a local update, failed for the same reason.
My phone is rooted via KingRoot (amazingly worked) but the bootloader is locked, so I wonder why the update fails.
With KingRoot there is an option to "Remove Root Permission" which I tried, thinking that it was the culprit. Then I tried to update and still it failed.
I was under the impression an OTA update fails only with a unlocked bootloader/custom recovery, but this does not seem the case. Any idea about what should I do?
Thanks,
Anubis

Hey man,
Just wanted to let you know: I have the EXACT same problem. Huawei AM7, KingRoot, OTA xxxB145 fail. I cannot further help, as I have no solution myself.
Hope someone can help.

Flash the stock image. Kingroot may have left some files behind even though you "uprooted" this the system is still seen as modified for purposes of the ota.

Did a factory reset, still software update fail. Then tried to install stock rom over the stock rom, but software update still fails...

Did you try local update from internal or external SD card?

Yes, tried that, but same 'software update fail' problem...

Are you sure that you are flashing the correct file for your specific variant? You cannot flash TL10 on L09, etc. It will give the error if you do that.

I found the problem:
1) When installing an OTA there is a check on the file system first and if it fails, the update is aborted
2) KingUser/KingRoot leaves the file system in a dirty state (there is a kinguser.apk left in /system/app) so the check fails
3) to install a clean OTA you need to have a clean recovery so you need to:
3.1) unlock the bootloader (to be able to install a stock recovery)
3.2) download the update (e.g. ...B145) you want to install
3.3) use the Huawei extractor to get the recovery.img file from the package
3.4) flash the stock recovery
3.5) upgrate with the OTA
I discovered it step by step. Basically you need to unlock the bootloader to fix things and therefore it is a waste of time to user KingRoot/KingUser in the first place: but faster/cleaner to unlock the bootloader and install SuperSU.

Still doesn't work I had the same but also had twrp recovery, I have my unlock code but no matter what adb I use I get remote command not allowed for trying to get stock recovery back or parse file failed with unlock code.
Any ideas would be much appreciated.

u need to be unrooted to proceed ota. ..

Okay,
I have been trying over and over but there is no way I can perform an OTA. Here's the situation:
- The bootloader is unlocked
- Current Firmware: MT7-L09 ... B137SP03. According to the updater it should go with MT7-L09 ... B145
- OTA fails: on WiFi, local update (SD), forced (three buttons)
- In the systems/app folder I have this "KingUser.apk" app, has been left hanging there by KingRoot when I removed it
I was told to reinstall the stock recovery and try a local update, here's what I did:
1) I downloaded again the current FW (B137SP03) from here: http://www.huaweiblog.de/huawei/firmwareupdate-b137-fuer-mate-7-ota/
2) extracted update.app, opened with the Huawei Extractor, got recovery.img from update.app
3) rebooted the Mate 7 (vol down + power) in fastboot mode
4) flashed the stock recovery: fastboot flash recovery recovery.img, got an ok
5) rebooted
6) put update.zip in the dload folder of the SD, performed a local update --> failed as usual
Is there anything I am doing wrong?

"UPDATE.ZIP" ??? I wonder that stock recovery may flash a zip file.
Check elsewhere in this forum the matter of the trash files left by kingroot, intead...

Did you read what I wrote?
The OTA is called update.zip and you can perform an update by putting it into the dload folder of the SD card and then using the updater or with a forced update (three buttons boot).
The recovery file is called recovery.img and it is inside the archive update.app which is inside update.zip
Anubis

Correct. But you wrote "put the update.zip file in the SD folder".
I suppose you mean the EXTRACTED update.app file in the SD folder.
That's it.
Anyway, peace and love.

No. I put the update.zip file in the dload folder of the SD card.
About removing KingRoot/KingUser after the self-removal option failed, I have only heard about installing SuperSu. Are you referring to it? Because that would imply to install a custom recovery, install supersu, clean-up, unroot via supersu, reinstall the stock recovery and then perform finally the OTA.
Paolo

:good:

oh well... Did everything (KingUser was removed with the support of SuperSuMe), reverted back to the stock recovery and guess what? Software update failed as before.
I guess I'll have to stay with my firmware until lollipop or a custom rom based on lollipop will come

Hello,
tuddu is wright. The file which must be put in the dload folder is update.app and no update.zip.

I wish it would be that easy. It makes absolutely no difference whether I put in dload update.zip or its unzipped content.
the message is always "software install failed".

You should do a clean install ( 3 buttons ) of the full B137 firmware, it was happening also with my phone and I solved the issue in that way.
After the flash you'll be on a clean stock B137 so you can put the "update.zip" in the "dload" folder ( it's an OTA update, not a full update.app firmware ) and be able to get the latest B145 :good:

My honor 8 refuse update

hello, i will try to explain my problem :
My honor was bricked by an error of flash.
I have "repair" it by a way found here on xda : flash boot.img, cust, recovery, system, and after i have could make the update by dload.
Then all was ok under the firmware LO9C432B131.
But now, i can't update to B360...
Before my brick, i had the ota update to B360... but now i have nothing....
If i try the update by dload, it says : "problem compatibility"
I have downgraded to B120 and ota update was good for B131. But nothing for B360
If someone can explain me...thank you so much (actually the phone is no rooted and relocked)

Hi there. Go through the entire rollback procedure and you will be fine: https://forum.xda-developers.com/honor-8/how-to/guide-downgrading-unlocked-rooted-twrpd-t3549281
Put the update.app file in a folder called dload on a SD card. If you haven't got one, flash twrp in fastboot and when in twrp you'll be able to transfer them to internal storage from your pc. Then follow the instruction above. That's how I unbricked mine. Good luck.

I don't think you understood what OP is saying. He successfully rolled back to MM but he cant go to Nougat anymore.

Yes, but I believe the issue comes from manual flashing of partitions. I have also tried that when my phone was dead and the recovery and eRecovery always threw "package incompatible" error. I think restoring the entire file system to factory condition (which happens during the rollback process) is the sure best way to fix all issues.

Thanks for your answers,
I finally got the update with the charlie app...(not easy this method !)
But now i don't know if ota will be ok...
I will perhaps do the rollback as you said to restore the entire file system...

Bricked Honor 6x, no OS, no Custom Recovery

So, the thing is im pretty new here.
I had Marshmallow on my 6x, i had TWRP, then I performed a wipe of every partition (except of Micro SDcard) and installed Resurrection Remix.
It was installed, there was a little Problem, so i wanted to go back to the Stock Firmware.
I wiped it again, and installed the first one of the update.app's (from http://www.stechguide.com/update-honor-6x-to-android-nougat/ ) via dload Method.
Then the second update.app was installed via dload Method. I wanted to reboot the device, but now it doesn't boot into Nougat. Instead it boots to eRecovery.
And now I'm stuck here, no OS and no TWRP (problably got removed by first Nougat update.app)
So is there any way I can install a new OS? or maybe wipe the system partition for a clean start?
THX in advance,
-Paul

Man I don't know. Can you connect via ADB to a pc ?
If so you can try to install MM update B151 full from http://hwmt.ru/oth/HWFF/info/view.php?find_model=

Depends on your system. If you talk about commands I guess you're on Windows (I'm not). Then search the web or wait for others to respond.

Dload method is your friend

yes it helped me a lot of thanks to @shashank1320
he given his valuable time and personally assisted me on telegram
what is the ultimate solution of all type of brick is dload method
many people says it works with internal storage ,works with twrp intstalled need to put this or this file into dload folder etc etc
my experience is this
NONE OS METHOD WORKING NEITHER FASTBOOT FLASHING ANYTHING NOR TWRP RESTORING BACKUP OR FLASHING ANYTHING
FINALLY I TRIED DLOAD METHODS BUT IT DIDNT WORKED AT THAT TIME
MISTAKE WHAT I WAS MAKING WAS THAT I WAS USING FIRMWARE WHICH WAS ON OFFICIAL SITE OF HUAWEI
LATER @shashank1320
GUIDED ME TO DOWNLOAD THE FIRMWARE EXACTLY SIMILAR TO MY PHONES FIRMWARE THIS IS MUST IT SHOULD MATCH WITH YOU FIRMWARE
THEN PUT ALL THE FILES UNDER DLOAD FOLDER(THERE WERE 4 FILES)
SOME SAYS JUST PUT UPDATE.APP BUT FORM ME IT DID NOT WORKED SO I PUTTED ALL 4 FILES UNDER DLOAD FOLDER CLEANED ALL OTHER FOLDERS,FILES FROM MY SD CARD THERE WERE ONLY DLOAD FOLDER
SO I SHUT DOWN PHONE THEN PRESSD ALL THREE BUTTONS TOGETHER(POWER +VOL UP + VOL DOWN) AND AFTER STUCKING ON HONOR SCREEN FOR 5 6 MINUTES ITS STARTED FLASHING
AND I GOT MY PHONE WORKING AGAIN
HOWEVER MY BOOTLOADER AND FRP IS STILL UNLOCKED
TWRP IS STILL THERE I DONT HAVE STOCK RECOVERY AND BUILD NUMBER IS NRD90M TEST KEYS
BUT IT DONT MATTER FOR ME NOW
THANKS @shashank1320 @RedSkull23
BOTTOM LINE IS DLOAD METHOD IS ULTIMATE SOLUTION IF YOU DO IT CORRECTLY.

How to flash via TWRP a stock ROM in my problematic phone

Hi everyone.
I am facing a LOT of troubles with my phone (as stated in this thread).
Anyway now I have again unlocked bootloader, installed TWRP 3.1.1, rooted but I have a strange ROM installed by a service tech shop after the phone became unusable.
The problem is that this ROM does not show an update option in settings so I am stuck at 1st march security patches.
Here attached my actual Build Prop file.
The ROM seems to be a BLN-L21C900B300 (never heard of this and not even found on Firmware Finder) and the fingerprints show a "test keys" rom:
device: HWBLN-H
Display: BLN-L21C900B300
Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys​
If I try to flash via TWRP a BLN-L21C432B360 (which was my previous stock ROM) it does not work and on TWRP appears the following:
......
write radio image
check_write_data_to_partition
write data error
E; unknown command (errno)
update_huawei_pkg_from_ota_zip: update package from zip failed
updater process ended with ERROR: 7
error installing zip file '/external_sd/update_full_BLN-L21_hw_eu_zip'​
I cannot flash the FULL zip file with the core of the ROM but I can luckily flash the data, so I could get back Radio Fm and possibility to install themes....
To make the story short: is there someone who knows what this error is? Maybe I can get a solution.
Moreover: maybe this strange "device: HWBLN-H Display: BLN-L21C900B300 Fingerprint: Huawei/generic_a15/generic_a15:7.0/NRD90M/jslave04010520/:user/test keys" is preventing me to flash?
Changing build prop file can be useful?
Thanks to all.

I forgot to mention: dload not working. Always error.
That's why I think TWRP is the only solution

B300 (at least for the BLN-L24) is the first of two update packages to rollback from Nougat to MM. The first update will take you from the latest firmware to B300 and then the second update will complete the rollback to your device's stock firmware.
dload this package to complete the rollback then do a factory reset and wipe cache partition in stock recovery. After that download and update to the latest firmware and proceed to unlock BL and flash twrp and you should be good to go.

And before doing it I have to flash the stock recovery?
My phone was, we can say, flashed in some way by the tech shop to this strange version of Nougat and with the "test keys" fingertips.
With the files you provide I should "dload"?
I do not understand your post.
please explain better.

My phone was, we can say, flashed in some way by the tech shop to this strange version of Nougat and with the "test keys" fingertips. Like I said they did half of the rollback process which is why you are on B300 firmware that you cant find available for download

Download the zip I linked above from Huawei website. Extract the update.app and put it in dload folder on your external SD card and force flash (power vol - vol +). It will flash all the stock images and return your phone to factory firmware android 6.0 EMUI 4.1. It might bootloop after this but booting into stock recovery (power vol +) and perform factory reset followed by wipe cache partition will get you booting. Then you can OTA update to latest firmware and root again.

Well, I will try this weekend. Now the risk to stay without phone during working days is too high
Ah, BTW, thanks for suggestion.

Haha I know the feeling. First time I went to rollback i jumped the gun and said screw it only to have my phone brick and no access to adb/fastboot until the next morning.
As usual. Huawei sucks. Full stop.

I agree 100%
Since you have nothing to lose right now just try the whole rollback process. Here is the update that the service center used to get your phone to BLN-L21C900B300. You can try flashing that again through dload or skip to trying to flash this. There are two different firmwares listed as the 2nd part of the rollback and you already said the last one I gave you failed so give this one a shot. Let me know how it works out for you:good:

I tried, gives me always error after entering erecovery. Same as above,
Software install failed.
Incompatibility with current version.

Have you tried the Team MT huawei multitool to flash the images from the firmware? Use the Huawei update extractor tool to get the boot,cust,recovery,system and userdata.img from the firmware you tried to flash and then put them in the unbrick folder in the multi tool. Put phone in fastboot and run the Multi tool and use the unbrick option. I know your phone is not bricked but this way it will flash all 5 images in order through fastboot. You could actually try and flash the most current firmware with this method and avoid having to system update from MM to Nougat.

yes, exactly, I am trying with multitool . another bro suggested me how to do it even if with a slightly different method.
"You need flash the oeminfo via multi tool and then same firmware file for your current version via dload. It should be fixed".
WTF....never sweat so much for a phone. And never had those problems flashing samsung... and I was flashaholic

Yes, I have learned so much about this phone and the flashing/brick/unbrick process in the last 2 weeks.

When I go to multitool "unbrick", it asks for custom.img, but in no update.app of my firmware is present.
Moreover now I just can enter erecovery. It does not boot. I can enter fastboot only. Multitool is now not recognizing the phone. Do you know how to proceed?
I put in dload the firmware .app, but it says "software install failed"

Pheew...I managed to have again that fuc..ng C900B300.
I entered fastboot and repeated the unlock bootloader process. That way the phone got a hard reset and started over. Believe me when I say I tried all the methods I knew.
I think there is something locked somewhere in my partitions (I am not an expert of course) that prevent me to do deep modifications. Now I just can TWRP data but not the core. And again I have no update option. I think I am stuck forever at this stage with 1st march patches and nougat 7.0.
I do not think I will be ever able to have Oreo.
Amen. I am really tired to waste my time with this s**t. Next phone will be again a Samsung or One+. Full stop. Stop chinese brands.

Where are you located, Europe?

Yes

Ok bro I really hope this is it. Full firmware BLN-L21C432B151. I already downloaded it myself and checked with extractor tool it has all the images you need. Since you have fastboot back use the multi tool unbrick again and now that you have all the necessary images cross your fingers it will work.
And I agree with you about the phone. Made up my mind im giving this turd to my sister and getting the OP5T in a few weeks.

Thanks. I will do it this weekend. Today I spent 5 hours to get back my configuration after the hard reset with the apps I use for work. Cannot risk again tomorrow.
In another thread, sashank suggested to change OEM file because probably phone doesn't recognize the firmware I want to install.
It didn't work and lead me to start from scratch with the same strange build.
I will try your method but first I must study better the procedure because I don't want to mess up everything and risking to throw the phone in the garbage (where it belongs in the end...).
Thanks.

Developers options missing

Hello y'all, i issued a problem tomorrow by rooting BLN-L21C432, i unlocked bootloader with no problem, when was time for flashing recovery, i flashed the boot into the recovery and issued a problem in the dev options and security. Cuz of that, i can't access to adb, hisuite hdb to backup, and can't install extern apps without autorizations.
I tried all night long to resolve but no way, add to that the fact i've got a very very low connexion so 3-4h to load an update.zip.
So i downloaded b370, no way i can't use the dload method, fail at 5%. Same issue with b369. Tried to flash manually system boot and recovery by extracting update.app, no result, it's same. Tried to Unbrick via multi-tool, i use it on honor 7, but there's no cust image in update.app.
Build number is normal, C432B365.
I don't know what to do now, it's 10 hours i'm losing my minds with that phone. Please heeeelp :crying:

From which firmware ? Is it good if i flash boot and recovery from B360 ?
Edit : Actually the phone is in B365, it would be better if i try to dload from it right ?

I read that unlocked bootloader could block an update, is that true ?
