The system does not boot after automatic update - Huawei P20 Pro Questions & Answers

Hi
I have a very strange case with my P20 PRO 128GB Single Sim. About a week or two ago, I got a message that my phone found a new system update. I was very happy because I was still stuck on 9.1.0.311 because my phone never got the update to 10.
What was my surprise when it turned out that the update has exactly the same number that I have now uploaded to my phone.
I found that I did not have time to install the update yet, so I kept delaying it.
I was also supposed to do a data backup, unfortunately I didn't have time.
Last night my phone was updated. Unfortunately, it did not start normally after this update.
Constantly stops on the screen:
Your device has loaded a different operating system.
To learn more, visit:
http://zh.ui.vmall.com/emotiondownload.php?mod=restore
....
Your device is booting now ...
Then it goes to eRecovery.
I tried to do Update and recover system in this eRecovery, unfortunately after connecting to Wifi and trying to find information, I get the information Get package info failed
The Emergency backup option does nothing. The phone restarts and goes to the first screen Your device has loaded ...
I wanted to repair my phone via Fastboot & Rescue mode and HiSuite, unfortunately I get the information that "System restore is not supported on this device"
If I hold Volume Up + Power on the turned off phone, I enter the menu where I have the option Update mode and Clear data. In Clear data, I chose Wipe cache partition and then Safe mode, but it didn't help.
I wonder if by Update mode and, for example, through Memory card / OTG update mode or USB update mode, I would be able to restore the system and recover the data.
What do you think about it? Is there any chance to recover data (mainly photos and videos) or accept the loss and try to do Factory reset?

Note stuck in OTA mode - Upgrading from 4.0.4 to JB

Hello everyone,
I seem to have a problem upgrading my GT-N7000 to JB, the phone downloaded a 494MB update, and restarted to FOTA mode.
The progress bar went from 0-100% in about 15-20mins, but the phone has since then not completed the FOTA.
If I restart the phone by long-pressing power key, the FOTA restarts, but again gets stuck at the 100% mark. Pressing Vol Keys and powering on makes no difference.
Further the phone isn't recognised in Windows - says 'Device Malfunction'. The cable is fine, as it works with another phone.
My bad luck it was, the phone data isn't backed up - I never expected anything to go wrong. Is there a remote possibility of data recovery before I wipe the phone?
Now, how do I get back access to my phone, and how do I complete the upgrade, or reset the phone? I would be grateful if you help me or guide me how to proceed. Taking it to the service point would be the last resort, I want to try out everything I can before I send this in - it's out of warranty.
Regards
Abhishek

Dont worry. In general your personnel data are stored in internal SD and external SD, not disturbed by a system install process.
In that situation you'd better to install a new JB4.1.2 ROM using Odin in download mode.
Firstly see what ROM to be flashed. Official stock ROM, custom ROM, download it.
Read how to use Odin in download mode by connection USB PC-phone.
Odin is utility under PC. Download mode on the phone is entered after hold in the same time volume-down, home and power.

Failed downgrade from Nougat to MM bricked my EVA-L09

Recently I tried out the Nougat preview on my EVA-L09C636. It was ok but seeing as there was a problem with fonts and I'd lost root access, I began thinking about going back to MM.
To prepare for downgrade I tried using srktool to bring TWRP back (and I think this is my big mistake as srktool uses a TWRP made for MM, not N, is that right?). After I tried to restore TWRP I noticed "not recognised" errors when I connected my phone to PC again.
System recovery using hajuuk's Firmware Updater and HiSuite looked like it would complete but near the end of the process (the restoring system part) HiSuite aborted itself saying my device wasn't supported. This has left my P9 is in an unusable state where the only thing I can access is fastboot. Also I can't turn off my phone - holding down power simply makes it reboot then get stuck at the "Your device ... can't be trusted / Your device is booting now" screen.
Reading around a bit I attempted to unbrick it without any luck:
1. downloaded EVA-L09C636B152 update.zip from http://forum.xda-developers.com/p9/development/rom-stock-rom-eva-l19c636b168-t3419586 and installed Snoop05's 15 seconds ADB Installer.
2. extracted images from update.zip using Huawei Update Extractor and did
Code:
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
then tried rebooting holding volume up + power several times (but never got past untrusted device boot screen).
3. extracted contents of update.zip to folder 'dload' on a blank sd card, trying to force update several times by rebooting and holding down power + volume up + volume down (still never get past the screen saying my device is booting).
At this point I'd be happy to get anything happening on my phone - Marshmallow, Nougat or even some other ROM so I can use my device again.
Any ideas? I'm on EVA-L09 C636.

did you wiped data, cache, dalvik?

Hi! I'm not sure how to wipe data, cache or dalvik, because when I upgraded to Nougat this apparently removed TWRP.
Also I'm wondering if trying to use srktool to reinstall TWRP for 6.0 might have corrupted my 7.0 phone?
Is there any way to wipe data, cache, and/or dalvik now? Or are there other things I could try to unbrick?
Although my phone was in a pretty bizarre state - it would get hot and sit on the booting now screen until battery died - I was able to use DC Phoenix to make it boot up again. At that point it had no themes and only KitKat-esque icons. A reset and upgrade later icons and themes work and I'm back on stock Marshmallow. Here's an outline:
1. Google "Huawei Bricked phone repair guide with DC Phoenix", go to the first result and look at the instructions (I can't post URLs yet).
I used Method 1. But note! The newer versions of DC Phoenix are missing a feature that the instructions make clear you have to use. To get the original version used in their guide, you have to download the latest version of DC Phoenix, open it on your PC, then click "Enter Support Area" which logs you in to a download section. Find "DC Unlocker Softwares", "DC_Phoenix", then download DC_Phoenix_v14.rar and run that instead. Whether it's Method 1 or 2 make sure you complete it - i.e. the fastboot flash step AND a step they call "flashing in upgrade mode."
(Also note that for DC Phoenix you want to feed it the oldest version of firmware available for your phone, in my case b152. This is because themes and icons won't be fixed until it receives the next version of firmware as an update.)
2. Once I did the fastboot and upgrade flash, I did a system reset from the Settings app trying to get themes and current icons again. (This didn't work but doesn't do any harm or might have helped somehow further down the line).
3. I used hajuuk's Firmware Updater and HiSuite to upgrade to the next version of firmware available (in my case b168).
3. All fine and your phone is back to stock - icons look nice again and local themes are back. To get the original icons layout, go to Recents, hold down on the Trash Icon, show system apps, and Clear Data for Huawei Home.

I think I've bricked the Huawei P9

I have a European Huawei P9 EVA-L09 model which I adore. It was running Marshmallow and EMUI 4.1. I found a Nougat beta ROM and I tried to install it but have left it in an unusable state.
I don't think the phone is rooted but I do think the bootloader is unlocked.
I can boot into 3 modes.
Mode 1 - Just reboot
Huawei eRecovery where I get the options to download latest version and recovery, Reboot and Shutdown. If I select the Download latest version and recovery it setups my Wifi and then fails with the message Getting package info failed.
Mode 2 - Power + Vol Up
It boots into a screen that gives me the option to Reboot your System Now, Wipe data / factory Reset , Wipe Cache partition. Selecting Wipe Data/Factory reset returns back to this screen with an error - Red Exclamation mark. Selecting Wipe Cache partition seems to perform a wipe and returns to the original screen with the 3 options again.
Mode 3 - Connect to PC with Hisense and power + vol down
This goes into an android recovery screen which is white with a green android displayed
I have the USB drivers installed on my PC but I cannot see the phone in Windows explorer when I plug it in via USB. I do hear the recognition tone that Windows has recognised that a USB device has been attached. The Huawei PC software doesn't recognise it unless I go into the white android screen and select recover. This always fails saying it cannot find a package.
I have installed stock P9 Marshmallow firmware on my SD card in a dload folder (which is how I bricked it in the first place. When I hold Vol up and Vol Down and power it starts installing but then fails about 40% - 50% through. I have tried multiple versions of the L09 firmware but none of them install successfully.
I am not very technical and not an android expert so cannot say I have done everything perfectly correctly. #
Is my phone bricked or is it possible get my phone back working?
You can get your phone back, search the forums for dc phoenix, which has helped people including myself.
The other option is to go the huawei website, and look under downloads for p9. Find the two firmwares for beta rollback and follow the instructions, although i am not 100% confident that will work for you
use dc phoneix ... i was the in tha same condition
So I have installed and tried install a few different ROMs to the phone. DC Phoenix recognizes the phone as it comes up with the IMEI and version in the left hand window. It seems to install the ROM sucessfully.
I get a message at the end saying it finished successfully but when I boot back up it just goes straight into the same eRecovery screen I have tried B166 and B322 and no luck. Is there anything different I should be doing?
...and now I have a new issue
Thanks for everyone's help. After downloading and trying about 10 different ROMs I was able to get a Nougat ROM to install. Now I have a different problem
1. When I reboot I get a verification failed message. I get an option to go to eRecovery (which works the same as above and doesn't find a package)
So what I really want now is just to get back to stock Marshmallow and not have a verification message and not have some Nougat version that doesn't look like the official Huawei ROM.
So what next folks?
I encountered the exact same problem a few days ago. I didn't try DC Phoenix, instead sent it to Huawei for repair, claiming the phone was in a boot-loop I couldn't recover from.
They have fixed it now and the P9 is on its way back to me. What's strange is that they have swapped the whole motherboard for a new one! Didn't expect that.

Is there a way to back up your note 8 stuck in recovery mode no debug on

Hello everyone,
First things first I know I should have backed up the data on my T-mobile Samsung note 8. It's a freshman mistake. I did back up it once with smart switch ( so I do have the keys) but that was a long time ago.
My phone prompted me to do the system upgrade and Ignored and I skipped the promptings a few times. I finally accepted and I believe it must have installed the security upgrade without the base install and now I am stuck in recovery mode.
I have already cleared the cache and have the option to load files in ADB or from SD card. I am very preserving the data before I take and reset actions.
I am unable to access safe mode. I talked to Tmobile, Samsung, and Ubreakifix several times and no one had a good solution for retrieving the data. I hear that you can access files via ADB but I don't know if there is a command to back up all the data on the phone and later restore them to the phone.
I have important photos/videos ( not updated to google drive) and also notes I took with the Samsung pen. I am very interested in keeping this information. I did not have the chance to turn the debug mode on before this happened. I also tried doctor phone and it does not support the note 8 phones ( contrary to what it says). The phone is not rooted or anything, just right from the factory and files from the google play store and Tmobile. Is there a safe way to back everything up?
Thanks

Note 8 Stuck in Bootloop. Please help Recover or make backup

Dear All Respected Professionals,
My Samsung Note 8 SM-N950F Android 8.0 stopped booting all of a sudden. No software update, no modification, nothing. It was working perfectly, I restarted phone and it won't start again.
When I try to boot it stays stuck at boot logo (SAMSUNG logo) for around 5 minutes and then automatically restarts. It gets quite hot.
I can access via ADB while it stays in bootloop. I exported logcat. I'll upload if it may help.
I have around 2.2 GB free out of 64 GB internal storage.
Never rooted.
However, it seems like Internal Storage doesn't get mounted. I can’t access /sdcard or /storage/emulated/0
As much as I remember, I had "Allow OEM Unlock" enabled. I tried to flash TWRP via Odin in Download mode, but it fails.
I'm looking to
1. Revert phone to working state without formatting
2. If 1 is not possible, I want to at least make complete backup, something like nandroid to backup WhatsApp data and other stuff.
Note: I want to recover data from my phone. It has lots of important data. I don't want to simply format it.
Device: Samsung Note 8 SM-N950F
ROM: Stock Android 8.0
Never rooted
I can boot into Recover and Download mode.
This is my first post here. If any more details are needed please ask and I'll provide.
Kind people here please help me fix my only daily driver???

Trying following below steps..
1. First try to force restart device by pressing Volume down + Power key for 7 to 10 sec. It will fix system crash issues
2. Go to recovery mode and try to wife cache partition, ONLY WIPE CACHE PARTITION. DO NOT WIPE DATA/FACTORY RESET.
3. Try to boot device in safe mode, Press and hold volume down + power button, When you see Samsung then release Power button but keep holding volume down button until home screen.
Let me know results...
im having similar problems,
any results?
