Huawei P9 EVA-L09 stuck on eRecovery, factory data reset failed

Hello friends
I find myself in a very delicate situation
I have a P9 EVA-L09 32GB with B181 version of software, android 6.
After a failed update to android 7, the phone only normal starts in eRecovery where i don't have usable options.
The phone can boot in fastboot and it enters fastboot where the 2 options, factory data reset and wipe cache partitions both can be used but at factory data rest says "reset failed" and wipe cache partition doesn't produce any visible change.
The questions is, can this phone be rescued in some way?
Can it be reflashed in any way?
Thank you in advance for your answers

from what i have read on the internet, there are 3 distinct functions:
erecovery = volume up and power
fastboot = volume down and power
fastboot&rescue mode = volume down and connect usb cable plugged into pc and using the hisuite software
i have a microsd card
can i reflash somehow a new firmware ?
i have read of another method using the pc and entering commands from the computer

you need a way to use your sdcard without the phone (sdcard reader or another phone)
if you have this follow this guide strictly:
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
with this guide you will get back to a working 6.0 Firmware and update it to latest Nougat 7.0 firmware.

thank you
i already did some searching on the net and the main issue is the unlocking the bootloader, this must be the first step, without this, its impossible to flash/rewrite anything on the phone
the problem at Huawei phones is that the unlocking is done through a code which either you get it free directly from Huawei or by paying third parties
there is one last problem, the FRP (factory reset protection) feature, which so sar is not very clear to me how it fits into the picture and what it does exactly

the problem of getting an unlock code is further more complicated if the phone cant be accessed from the menu or you do not have the box on which the IMEI, S/N and other data are written

There is no reason to unlock bootloader first. If u follow the guide above it will work. I was in the same situation.

i would like to ask you a different question but related
Is it technically possible for a phone, in this case a P9 to have a specific software version locked on to it? in other words, to be impossible to change the version of the software?
i am asking you because i have managed to reflash my phone and is working again but i was forced to put exactly the same version as before, B181.

If u are on B181 you can update to any version above if it matches your OEMINFO.
The guide i posted above will change your OEMINFO to C432 (EU Version) and after this u will receive every new update.
Any provide can use its own OEMINFO so if your provide dont push any update abbove 181 you are locked to this.
But again use the guide above strictly and you will get latest Nougat.
Short:
You cant be locked to any software version at least if you are on C432.

i received OTA to B182 and immediately after installation i got OTA update to B372
problem solved, learned a lot about Huawei software system
thank you for your help

Huawei p9 always rebooting every 2 minutes

Hello everyone,
I'm new in xda's forum and so that's my first thread.
I hope you can help me.
I have a Huawei P9 EVA-L09C02B357 that lately it automatically reboot about every 2 minutes. The interesting things is that it happened only if I boot the ROM (stock or not). But in recovery mode (or erecovery) or fastboot mode, this automatic reboot doesnt manifest.
All is started when I have tried to install RROS Nougat on my phones and it was working when i tried to turn off the phone and then turn it on but nothing, the phone was stuck on boot phase.
I decided to switch data file system from f2fs to ext4 and then reinstall it as the guide explains.
https://forum.xda-developers.com/p9/development/rom-t3606185
The ROM worked correctly except the fingerprint sensor.
During the first configuration, it scans my fingerprint but for a bug, i couldnt go over the first scan.
Searching on the internet I understood that the problem could be the modem. But for a mistake I have flashed the wrong fix for the modem (it was for another phone, don't ask me how I didnt notice it).
Now even with stock rom or custom the phone has this automatic reboot. Particularly the stock rom has many bugs every time i flash it, like: there isn't the IMEI, there aren't any preinstalled apps, is really slow in some situations and the default keyboard is the voice typing...
I think the solution is to flash the stock modem, but when I try to flash it via fastboot, it says: "No suitable files selected. Check profiles.xml".
Thanks in advance
P.S. sorry for my bad english :C

Can you send me the MM firmware?

To go back to android 6, my phone should have android 7 installed? Cuz now i have some problems to flash it.

UPDATE
Thank you so much vampirian!
I have successfully installed android 6 and the automatic reboot is gone.
Now i'll try to update it and probably retry to install RROS .
(yes i'm stubborn).

I know I don't write a lot of things or give you all the links. But it was good for you to research and learn more about your device good job and good luck with rros (although is dated and its not really worth, but that's just my opinion )

This is not the serial number (of your device) but the stock firmware build mame/number
If you debrand to c432 (EU) from your c900, you will automatically receive (must have SIM card in) OTA updates first to b242 (over your b182) and then further OTA updates up to b399 or even b502
PS: For debranding to c432 you can use this guide

If you have debranded to c432 as suggested in my previous post, let it update as far as it gets (b398, b399 or even b502).
Once it stops receiving OTAs, perform Hard reset with wiping Internal memory (you can do it from Settings or from eRecovery)
Btw, if it attempts an OTA but it fails, then go back to the updating screen and choose Full update, instead of (default) differential update.
Which ROM to suggest you - Magic Rainbow v4:

Now the phone is installing the b395 update. Is the hard reset necessary?
I knwo the existence of Magic Rainbow but i didn't know that it is based on Emui. I'll download it because i guess it is more stable than RROS.

It seems that i cant go over b395.

Are you now on EVA-L09 c432 b395, exactly as that?
You do not receive further OTA, or you received OTA but it failed (in that case force Full update as suggested above)?
If you're really not receiving OTA b398 or b399, try Hard reset with wiping Internal memory - if still mo OTA, install b398 by HWOTA method
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
Once you reach b398, you're ready for MR v4.

If you boot to eRecvery ( Vol+ and Pow) you will find Hard reset option.
Similarly, under Settings /Advanced Settings/ Reset phone there is also hard reset option - cannot tell you better details, I have TWRP and MR v4, I don't have these options.
Also if you 'dial' ' *#*#2846579#*#* a hidden Project menu will open, with Restore Factory option

The only method that i know to go in erecovery, if bootloader is locked, is by using PC and know i can't...
What if I use firmware finder?

Both two last options as listed (Settings and Project Menu) are present in stock ROM.
And you can boot to eRecovery as above - shut down, then press and keep pressing Vol+ and Pow together
If not OTA, then the best way for manual updating is HWOTA, I gave you the link also above
But still, you didn't confirm, are you really on EVA L09 c432 b395, ie, you are not on L19 (by mistake)

I was on EVA-L09 c432 b395 and now I'm on b502. I tell you what I did.
I tried to make a reset bt the Project Menu option but, the reset it didn't gave any update...
So I tried with firmware finder (android version) and I used the DNS method. I have chosen the b397 OTA and the updater found it.
During the download, it arrived at 25% and suddenly the phone has found the b502 for a total of 4 patch to download together (I dont know how to explain that thing).
After download the phone reboot for installing phase but it failed... and on boot it appeared a red warning, then i went to erecovery, shut off the phone and go to recovery mode for a factory reset.
Factory reset was a success but on boot the red warning still appear but i tried to continue to boot... fortunately it was all ok but the phone was on b395.
It magically appeared the screen for b502 Full-OTA update and now I have it!
I wouldn't understimate you but I always prefer to try solution by myself.

HELP! Bootloop after android pie update using Hisuite

Hi every one. I can't find solution to my problem so I decided to ask your help.
Few days ago I read that I can update my Huawei p10 to android pie officialy through Hisuite. Scanned for update and it said that I'm on the latest android which was emiui 5.1 so I started to look for a way to force it and found solution (will be posted bellow).
After it Hisuite found pie 9.0.1 update and after downloading the files it started installing it. After that it loaded 100% and rebooted, then rebooted again and again and again... shortly realised that it's bootlooping. Tried to turn it off and yet it kept bootlooping, took it apart disconected battery and hopped to enter recovery mode or fastboot, boot as soon as i plug the battery in and put usb or power on button same thing continued and i can't enter those modes whatever i do. Can anyone help me with this?
Oh yeah, I've tryied this methode on mate 9 pro from 5.1 to 9.1 and it worked flawlessly, then right next after that I attempted p10. Also i think i didn't do anything with firmware finder couse i saw update anyway.
Also on backup photo Details it shows build VTR-L09C432B171 ithat was before me trying to update it
Update methode
"Instructions how to get an authorized version of EMUI 9 on EMUI 9 via Firmware Finder
Attention, this method requires more success checks.
1. Add a line to C:\Windows\System32\drivers\etc\hosts
188.225.84.142 query.hicloud.com
2. Download and install HiSuite9.0.2.304, BUT NOT RUN:
3. Replace the files:
httpcomponent.dll move with the replacement in C:/Program Files (x86)/HiSuite or other directory in which the application is installed HiSuite
HiSuiteConfig.xml move with the replacement in C:/Users/YOURUSERNAME/AppData/Local/Hisuite/userdata/UpdateDogDev
4. Open FF (any, I like the smartphone to register - less action)
Looking for a permitted Android 9 for your device on the principle: device_model: VTR-L29 or VTR-L09,
NOTE: Firmware must be approved for your IMEI
Once again, make sure it is permitted, registers the update for eRecovery.
NOTE: There are two types of firmware: CHN, i.e. for Chinese devices and OVS, for all the rest. So if you do not have Chinese firmware, then you need to pay attention exclusively to OVS.
5. Run HiSuite, connect the device, looking for an update, update, enjoy."

IIm still lost. Is there anything i can do?

SOLVED:Soft-brick Huawei P30 pro:Your device has loaded a different operating system

I already sent a private message to a Recognized Contributor on XDA.I think that If post here I could help also other members.
I have problem with my new huawei p30 pro.It was stuck on android 9 and emui 9 ,I tried every official modes to force the update.But I couldn't achieve that.
So I tried with hisuite proxy .I finded my Device model(VOG-L29) region: C431-HW-EEA , then clicked on add rom on firm Finder v2 .The version was the lastest 102.0.0.134
The procedure was smooth and I choosed the right ROM (100% sure!I already have that webpage open)Once finished the smartphone installed the EMUI 12 but once restarted the massage: Your device has loaded a different operating system! scared me .
Do I broke the phone? Is there a way to fix it without changing the motherboard?
Thanks a lot every help will be appreciated so much

Little Update.
I tried several methods trying solving this big issue.
1.Update from Erecovery trying to download and recover the package via WIFI
RESULT:the phone updated from 12.0.0.134 to 12.0.0.149 but once rebooted the
same result with black screen and the massage: Your device has loaded a different operating system
2.I done the same procedure of this guy
I also saved the log file of hisuite and here are the version before I made that mess:
* FirmWare_Base:VOG-LGRP2-OVS 9.1.0.240
* FirmWare_Cust:VOG-L29-CUST 9.1.0.4(C431)
* FirmWare_Preload:VOG-L29-PRELOAD 9.1.0.2(C431R2)
So The ROM I selected on huawei firm finder v2 was good(VOG-l29 102.0.0.134)
I succeeded to Recover and install the previous ROM,the 9.1.240,with hisuite and hisuite proxy
but once finished an error on the p30pro appear: Software install failed.
tried also the 10.0.0.195
I'm thinking about dload with otg or nm card but I don't know the procedure.
Could you guys help me?
Thanks

As the title changed I solved the problem of soft brick.
I write here the tutorial to help those who might have the same problem.
Requirement :OTG cable ,exFat formatted pen drive and the right Firmware to flash.
Create a dload called folder inside the pen drive and put in it the 3 Firmware's .zip file(base,cust and preload)
I specify that my p30 was bricked on version 12, so my first attempt was to load the version
VOG-L29 hw eea VOGUE-L29C 9.1.0.115(C431E4R2P2).
To flash the firmaware from usb pen take the phone off and hold the volume up button for several seconds while we connect to charge the phone .Connect the usb pen and from erecovery choose OTG update mode.
The result was an unbricked p30 pro but no fast charge and usb data tranfer and I can't get any type of update from OTA.
So I downloaded this version:
https://huaweidownload.com/download/p30-pro/vog-l29-2/10-1-0-123/
I flashed my P30 Pro once again, and of course no USB connection and fast charging. But system afetr few minutes started finding upgrades via OTA. Passed from 10.1.0.179 to 10.1.0.201. Of course I let it upgrade.
It was 11.0.0.138 first, then 11.0.0.174(last EMUI version before version 12 ) came and USB connection was restored.
you can also find other firmware here:
https://androidhost.ru/search.html
https://www.hardreset.info/it/devices/huawei/huawei-p30-pro/faq/firmware/huawei-firmware/
Even if I am a programmer I am new in the world of android bricks and I spent 2 afternoons and many attempts to solve the problem.
The last problem concerns the creation of a backup point. I have tried different version of HiSuite and both windows 10 and 8.1.But I couldn't get data from phone
The solution is to install the Androis ADB inteface Drivers while the phone is connected to the PC. I believe that this way data information is injected to the phone as well as installed on the PC.
take the drivers from here: https://oemdrivers.com/usb-adb-interface
or here: https://www.drivermarket.net/adb-fastboot-drivers-v1-4-3-download-for-windows-latest/
once you carry out this procedure you fixed everything
