Hard Bricked P9 Lite

Hi, i have a big problem: my phone isn't starting up anymore. Yesterday i upgraded to Nougat, and all was fine. Then i decided to install Revolution ROM, so i flashed twrp for 7.0 and then flashed the ROM. Phone started up correctly but then i decided to wipe data so i can have a "clean" installation. So i rebooted into twrp and formatted data. After this, phone get into bootloop. Just after that, i couldn't boot into twrp, and when i tried to boot in, it stuck in the yellow text "Your phone is booting up...". Then i downloaded b160, extracted it with Huawei Update Extractor and flashed all(system, boot, cust and recovery). This didn't work, i was stuck in the 3 choices menu with text "Your phone is booting up...", can't even see Huawei's logo. 1 hour ago i installed from sd (3 buttons way) b160, installation successful and now i can see Huawei's logo, but after that black screen . I tried to reboot into bootloader but i don't see anymore yellow "unlocked phone" text. I can just boot into eRecovery. Right now i'm trying to download b100 and trying to see if i can fix it by myself :fingers-crossed:. If u can, please help me, i really need help to get this phone working again.
(Sorry for my bad english )
Edit: i posted in wrong section, sorry xD
Edit 2: i finally boot into bootloader, but "PHONE Locked" . How can i unlock bootloader again? I don't have that code anymore and i can't boot into system..

I've alredy tried with 2 different firmwares: b130 and b120 but both say that they're incompatible.. Right now i'm downloading b100
(btw, my phone model is L-21 dual-sim)
Edit: I've tried to install b100 without any success. Everytime i try to install a firmware it says "Software installation failed! Incompatibility with current version. Please download the correct update package"
I heard about "oeminfo.img", because before having theese problems i was in 7.0 and to rollback you need to flash this oeminfo.img, but i can't flash anything .
Please help me, i'm alredy losing hope to repair my device... What should i do?

Ok so I've installed an update but I got a black screen. All I had to do is to clear cache and wipe data etc (in recovery option), then reboot to "dload mode" and... well, it works !

Huawei p9 EVA-LC09 NRD90M test-keys no apps

Hello guys, I read lots of topics about this issue and I would like to explain mine.
I wanted to try Android 7 so I decided to update with B378 firmware.
First of all I got unlocked and rooted phone and I made a huge mistake because I forgot to unroot it before flashing the new firmware.
By the way, I flashed the B378 firmware following the dload method using the *#*#2468579#*#* menu and it worked.
At the first boot I immediately noticed that the phone was missing of all the system apps including camera, calculator, flashlight, keyboard.. and the build number appears to be NRD90M test-keys. The updater menu disappeared as well.
About the keyboard I fixed the problem simply activating it in the settings menu but all the apps were still missing.
I saw I had to flash the B378_update_data_full_hw_eu to restore the apps and here started the odissey.
I couldn't boot the recovery cause it was incompatible with Nougat so after a long search I found the TWRP 3.0.2-N and now it works.
I downloaded the B378_update_data_full_hw_eu.zip package, unzipped it in the dload folder but the hidden menu (*#*#2468579#*#*) isn't there anymore. Nothing happens when I digit that code.
So i tried to boot the phone with vol +, vol -, pwr button pressed and the emui recovery installed the package. Installation was 100% succesful.
The apps are still missing..
What's next step now?

A prerooted device not allows to flash hw/eu. Its your choice, downgrade, or Factory reset + flash the data package with dload.

now my device is unrooted, the hw/eu flashes correctly but I still don't have the apps.
So I could try to wipe and factory reset via recovery and flash again?

Well I think I did worst than before..
I wiped and formatted from recovery and installed again the b378 firmware using vol+ vol- pwr combination (I had to do like this cause the hidden menu doesn't work), the flash was ok 100% succesful.
Before I still have the keyboard because I updated from my previous firmware but now I don't have it as all the other apps.
I tried then to flash the sw/eu, installation succesful 100% but it's the same! No apps, no keyboard, no updater menu....nothing.
What can I do? Format everything again and flash another firmware? Any suggestion? Which one is the best one for android 7?

Hello
I had the same problem. Wrocł the MM 136 and late 182, 360,361,378. I have all the applications and it works perfectly.

Only Downgrade and upgrade can solve it. But dont forget to unlock on b182 if you want root on B378.

Thanks

[SOLVED] EVA-L19 "Software Install Failed" when updating

Hi everyone,
Just taking my chances if anyone in here encountered the same issue. I'm currently on EVA-L19C636B381 and the System Updater is asking me to update to B390. However, I've tried downloading the update several times but keep on getting the "Software Install Failed" error message. Any ideas on how I can update the firmware and ensure that updates will be installed seamlessly moving forward?
Note that the bootloader was unlocked before and it used to have TWRP. Now I've relocked the bootloader and installed the stock recovery.
Thanks!
Clarification:
Version: EVA-L19C636B381 (everything's stock: BOOT, RECOVERY, RECOVERY2, SYSTEM)
Would like to update to: B390
Issue: Getting "Software install failed" error message after downloading through System Update
** Used to have TWRP and root. Flashed stock IMGs
Update:
Issue solved! Please see last post for the update/solution.

If you had TWRP, maybe you also rooted - root will also block OTA (you had to unroot in that case).
Btw, unlocked bootloader does not prevent/affect OTA

Hi zgfg!
Thanks for the response. Yeah, if I'm not mistaken, it used to be rooted. However, I've installed stock B381 and stock recovery already, and still getting the error message. Checked with Root Checker and it says that there's no root access.

Rooting affects Boot partition, it must be flashed back to stock. And it's recommended to Hard reset then, before OTA. For OTA, go to Settings, and choose Full upgrade

Yeah, that's what I did. Basically, everything's stock already. That's why I don't understand why I'm still getting the error message.

You can try downloading the full stock rom package and manually update with the dload method.

Hi noalt! Thanks for the response.
Yeah, kinda wondering if that'll work. For the dload method, does it really require an SD card? Also, for the dload method, it is okay to get the latest full package instead? (Upon checking using Firmware Finder, the latest one is B395 or B396)

Any steps that I can follow to do a sort of "clean install"? As in free of any modifications? In short, some kind of steps as alternative for using System Update (which I can't use due to the error message I'm getting)?

You can use any stock rom you like. If it is the same or higher build, you may not need to do a rollback. The dload method only works from sd-card. It will be a clean install.
I think the dload method is the safest. Alternatives are flashing images indiviually through fastboot but I have no experience with that, except for the recovery.img

I see. Regarding the dload method, if by sd-card you're referring to the internal memory, I'm afraid I've tried that (creating a dload folder and putting nothing else but the UPDATE.APP file inside) and I'm getting a Software Install Failed error message as well. :crying:

No, I mean a micro sd card. You can put one in the tray next to your sim card. And then you have to shut down you phone and boot it holding vol+ vol- and power until you get into the updater.

Ah yes, that's the one that I have yet to try (as I don't have an SD card, the other spare phone that I have is a 5s).

UPDATE:
I eventually was able to install EVA-L19C363B395!
Initially, I was having issues with the partitions (as I tinkered around a bit with TWRP) and was stuck with the Huawei logo and not proceeding with the booting. So what I did was I flashed BOOT.img, SYSTEM.img, RECOVERY.img, and RECOVERY2.img from the stock B381 (use the Huawei Update Extractor to get it from the UPDATE.APP file from the update.zip (the large file), do some Googling to find it here in XDA . Then I was still experiencing the said issue so I used the stock recovery's features: "Wipe data/factory reset" and "Wipe cache partition" to sort of repair the issues with the partitions (didn't know how to properly do it in TWRP.
Then B381 booted and was able to access USB debugging (initially had issues with this as well, after flashing images, Settings app kept on crashing when trying to access Security and Developer options).
And then finally followed the HWOTA procedure made by @Atarii. Make sure that you're going to use the proper recovery file for your version (L09, L19, etc). According to the steps, being rooted is also required so I used @zgfg's SuperSU 2.82 permissive (https://mega.nz/#F!w41RmZKB!IG53JadhjUKgFK8anbctIw). Make sure to flash it before flashing the nocheck recovery file.
And voila! That should do it. Based on what I'm seeing, root has been removed after doing the HWOTA procedure, same goes for TWRP, and bootloader's locked again.
Thanks to all of those who responded and credit goes to @Atarii and @zgfg for the procedure and file/link.

Hi,
I have the same problem, is anybody could help us?

Hi,
I finally unbricked my phone by forcing installation of update Full-OTA B357 from SD card.
Here is the URL I followed :
http://www.stechguide.com/honor-5c-b357-nougat-update/
In step 1 just replace the step with *#*#2846579#*#* by a cold start while pressing up and down volume keys.
For step 2 you can proceed like indicated.
My phone is back! I was able to install B359 right After using OTA notification.

Hello,
I've the same issue, but it is a NEM-L22C636B355.
Unfortunatelly, the process ends with "Software install failed".
What can be wrong?

first think phone must in stock recovery, honor 5c use 2 recovery. you can reflash recovery image via adb command. after installing recovery and recovery2 you can flashing via dload metode, cek the firmware there can single zip/2nd or 3rd zip if getting from ffinder. sorry my bad English

go to fastboot mode from power off phone, to flashing stock recovery. then copy update.app for flashing rom from sdcard via dload mode
btw , emui 4 or emui 5 last instaled at your phone?

It was EMUI5. Then I've installed a twrp recovery and SuperSu.

I've succeeded to restart in fastboot&rescue mode, but my phone is:
PHONE relocked
FRP lock
So when I try to unlock oem, it fails.

if you have twrp recovery, then you can installing rom with "fullota-mf-pv" version. but cek the firmware, usually there in 2/3 zip. update.zip, full_data_xxxxx.zip, update _data.zip. flashing update.zip in last(full_data first then update.zip) booting more time, be patient

After some tests
I've rechecked.
When I start with Vol+ & Power, the phone tries to update the ROM and fails.
"Software install failed
The update package does not exist.
Please download the package again"
My interpretation is that the installed Recovery is stock.
When I try the dload method with an update.app in the dload folder of a sd and if I start with "Vol+ & Vol- & Power", I have:
With NEM-L22C636B150 update.app,
I get the message:
"Software install failed
Incompatibility with current version.
Please download the correct update package.".
My interpretation is that the phone is not EMUI4.​
With NEM-L22C636B355 update.app and with NEM-L22C636B357 update.app
I get the message:
"Software install failed!
Get help from: http://www.emui.com/emotiondownload.php?mod=restore".
My feeling is that I don't have the right complete EMUI5 update.app file.​
Any comment?
Update:
I have unbricked my phone at the 8th tentative of dload method. As I had saved every thing with Hisuite, I've recovered all my data's and application. :victory:

Can you tell me how you fix your phone pls? I had a same problem as you and now my phone is brick, i can't do anything with it :crying:

Can you try dload method. If you are not aware, there is a guide in my signature. Try that, thats the best method to revive phone from any situation. Else check if you are able to download rhe firmware from erecocery.

Hi,
I have a L22C636. I fixed the problem with the Dload method (copy update.app in a blank sd). The only update package which worked was NEM-L22C636B355 . You need a full update firmware compatible with your phone.
You must try until success. I've tried 8 times.

Thank you so much, i have unbricked my phone using the dload method. Yayyy

Bricked Honor 5c NEM-L51 ?

Hi, I think i've kinda bricked my honor 5C (nem-l51), and I really need help :
A few years ago I rooted my phone to make otg work.
It worked a little while, but then a system update came up, could not update because of the twrp, so I tried to unroot it (from supersu) to do the update, and the twrp stayed after the unroot.
I stayed with the phone like this, twrp installed and update pending (still trying to install the update from time to time) and then I had to use OTG again and tried to re-root my phone.
I tried to flash the supersu files I used the first time, but, even when the flashing worked, I couldn't see the supersu app on the phone, still unrooted.
Then I tried to change the twrp (via fastboot) and I realised that I couldn't : I get the "command not allowed" failure when the recovery should get written. I tried with numerous twrp versions, and stock recovery.
So my twrp right now is the twrp-3.1.1-0-venus "OpenKirin edition" one.
The phone says it's unlocked and the frp is locked, but I can't remember if it was already the case or not when I first rooted.
I unfortunately don't have anymore the bootloader unlock code that huawai gave me originally. I have no idea how to get it again, to try to re-lock/unlock the bootloader.
Back then when I first rooted my phone, I made a back up, so I tried to restore that back up. It failed, first with "cannot wipe the cust partition". Then I tried to restore without restoring the cust partition, and I got "extracttarfork() process ended with error 255" while the system was restoring.
After that, the phone wouldn't boot into android anymore. It would be stuck at the unlocked bootloader warning message and then reboot after a few minutes.
So, lastly, I tried to install the unofficial lineageOS port from here : https://forum.xda-developers.com/honor-5c/development/rom-lineageos-14-1-honor-5c-t3713911 with my twrp.
The installation went well, but the phone is stuck while first booting in lineageOS (I let it overnight, restarted it, re-installed it, tried with the first release, nothing).
TL;DR: My phone isn't booting and I can't flash any new recovery.
Please, help me to get my phone working again

Give me the
old build number on emui
Update build you received..
Twrp working?
Fastboot?
Erecovery?

I got access to erecovery, even if the "download latest version and recovery" doesn't work. (erecovery connects to wifi, and the first thing it tries to check/download fails)
I can boot into fastboot but can't flash recovery from there because of the command not allowed problem.
I can boot into twrp, but the back up I tried to restore and the lineageos rom I tried to install both failed, so maybe the twrp has a problem?
I'm sorry I'm not sure about the build number, I'm pretty sure I was on EMUI 5.0 and android 7.x, and I think I remember comparing current build number vs the update, and it was something like B350 or B351 for the current, and B355 or B375 for the update.
I've found this in my backup file 'recovery.log' ro.omni.version=6.0.1-20160703-nemo-HOMEMADE and ro.build.id=MOB30M . So, that mean that I had android 6.x when I did the backup, way back at the beginning.
I thought the update never got installed because each time the phone would reboot to complete installation, it would reboot into twrp. But I've still updated from android 6 to android 7 somehow ?

NEM-L51C432 or NEM-L51C10 ?

Flash this via twrp
http://update.hicloud.com:8180/TDS/...-L51_hw_eu/update_data_full_NEM-L51_hw_eu.zip
Once done, boot to twrp and flash this
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1581/g104/v82938/f1/full/update.zip
Reboot.
If you are unable to flash the 2nd link then just use the dload method to flash this. If you are not aware of dload method, link is given in my signature.
Note, this 2nd firmware will replace your twrp with stock recovery. You should boot to b350 version and it will be full stock. Reason for flashing data file first is it doesn't replace the recovery to stock but just flashes your data, settings, apps. And 2nd link is main full firmware which will replace your boot, recovery, vendor everything and should boot.
Good luck

I flashed the first one, no error.
The second one had multiple errors :
"[...]
write radio image...
32k crc checked failure
E:unknown command [errno]
update_huawai_pkg_from_ota_zip: update package from zip failed
Updater process ended with ERROR: 7
Error installing zip file '/sdcard/update.zip'
Updating partition details...
...done
"
So I tried the dload method, and the installation started and ended at 5% with this error :
"Software install failed!
Incompatibility with current version.
Please download the correct update package."
I guess it's because I couldn't tell you the exact build number, I'm sorry for not taking note of it.
If there is a way for me to get the build number despite the status of the phone, i'm ready to do it.
If not, I'm ready to try as many versions as it takes to find the good one.
PS: I've still access to the twrp, thank god ! That was my biggest fear, because I can't flash any recovery in the current state.

You may try other higher versions like 360, 370 etc and see your luck. Twrp will be replaced only if the installation os successful for the main firmware. Its just a trial and error for you now but I am 99% sure you should be able to revive the phone via dload method

Thank you, it's reassuring. I will not give up until I test all the versions ^^
Could you help me a little bit to find other versions, please ? The only place I know where there is update packages for my phone is there : https://forum.xda-developers.com/ho...lota-upgrade-packages-models-nem-l51-t3473110 and there is only two versions.

Firmware finder website

Wow, thank you, I downloaded the firmware finder software, it has everything.
Should I flash the firmware in two steps like you first made me, or should I just try with only the dload method with the fullOTA firmware ?

Check dload guide in my signature. You can follow that now. Good luck

I tried b355, b361, b375, b377, nothing changes, same error.
I noticed that I have something related to an update in my sd card AND internal storage->HwOUC->140783->( update.zip[1.32GB], update_data_full_public.zip[344MB], update_full_NEM-L51_hw_eu.zip[412MB] )
I don't know whether these files were there before I did all these attempted updates.
Could it be that my phone is not trying to install the files I put in sdcard->dload, because he finds these files in the internal memory first, and each time try to install these ?
Should I delete them, move them, unzip them in dload folder ?

Copy them on PC and then try dload of files you downloaded from Firmware finder website.
These are files your phone downloaded for OTA update but as you were on twrp, they never installed it amd stays there

I copied the updates my phone downloaded on PC and then deleted them both on internal storage and sd card.
Then I tried dload method with b355,b375&b377 from firmware finder, and also with the update.zip I found in the updates my phone downloaded.
Nothing worked, all of them got the error "Incompatibility with current version. Please download the correct update package."
Should I try even more firmware versions, or should I try something else ?
Btw, I noticed my phone, when connected to my PC, is labeled as huawei-P9-lite, and I don't think it was always like that, but it's probably just because the twrp-3.1.1-0-venus.img is originally for the P9 lite.

I came accross this thread, where somebody recommends to flash stuff from fastboot.
I have not tried it yet, I only tried to flash recovery from fastboot, and it is failing with the "command not allowed". But maybe I could try to flash some other things ? Any advice ?
For now, despite all my attempts to install stock OTA via dload method, the phone is still trying to boot into lineageOS, and failing.

I came across the "current" firmware version with a check with DC-unlocker : "NEM-L51C432B120"
So I downloaded full OTA firmware b120 on firmware finder software, and the dload method worked !
The installation went well, and after a few minutes of the first boot, I got into phone configuration.
I have one last problem, though : the phone configuration is looping.
There is only 4 languages to choose, so I have to choose english(US), then there is a weird list of countries, none in the EU, where I feel i have to choose united states, then after some steps I have to register to huawei ID thing.
If I try to skip it, it loops to the language selection.
If I try to log in to my original account, it says "device not supported for your location" and then loops to languages. (my original account is in french/France)
If I try to create a new account with new address mail, it works but then at the end says again that "device not supported for your location" and then loops to languages.
I tried with other countries it still loops.
The other languages seems to be Chinese and Japanese, but the configuration is looping too if I choose them.
I tried with/without sim, with/without wifi connected...

Dload the next firmware now and see if it works. Then set the phone

I downloaded and installed with dload method (by removing sd card and copying directly on it the files, because I don't know how to have access to the phone internal & external memory now) the next firmware (b130 version)
The phone booted, it launched a "system optimization" that was a few minutes long, and then the EMUI configuration poped up and looped through language selection, region(country), wifi connection (successful), terms and conditions, and WLAN+(switch between wlan and mobile data automatically).
I feel like the phone is working, the notification led is even blinking when I receive sms, but I have access to nothing because of this damned configuration.
Note: the connection to huawei ID isn't prompted again in the loop once I log in, from the original or the new account. In order to be prompted again to log in to the huawei ID, I have to go to erecovery and reset to factory the phone.
