It should try to install upgrade from sd card after 4-6 restarts.. Put the update.zip or update.app (whichever you have) on sdcard, try to not into recovery mode, it will must probably fail and try to upgrade from sdcard...
The same happened with me, try it once
Thanks

If you have TWRP or CWM Recovery, do this
Since you're on bootloop, shutdown the device (press power key for few seconds until it completely shuts down). Then, press the following keys at the same time: Power + Volume Up for few seconds then as it vibrates leave the Power key but keep on pressing the Volume Up key. You will get to recovery mode and backup your data.
If no such recoveries then do this
Shutdown the device completely. Copy your current version or any other version (will be either UPDATE.ZIP or UPDATE.APP) in a folder , name that dload and paste it in your sdcard.. Now insert the sdcard into the phone, and restart it.. For few times, it may get in bootloop , if it gets, restart it again.. after few times, it will try to update the system itself and will find that dload folder in your sdcard and upgrade it..
That's it

Thanks again man
But I'm not gonna lose my data such as photos,videos and contacts?
Because all my data in the internal storage

You shouldn't lose your data since it is just like a firmware Update without any wipes. But I'm not gonna guarantee anything since idk what you did with your device.

Thanks for everything guys.
I will try it and give you feedback

I dont think if u have device off u can operate as it needs power to transfer data thought i m not expert i will follow other senior opinions also
And for Freezing there must be some app or some system file creating the issue for you
U can try flashing a Stock firmware using Odin which will keep all ur data as its and ocne it boots up take all the data backup and reset the device for error free experince
Note aftr flashing Stock firmware u ll loose root u need to root again u can use CF root method for the same

Not 3 button method.
Shut down, press power and vol+ button and soon as you see Huawei logo, release power button but keep pressing vol+ button until you enter recovery. Do factory reset.

You can follow the instructions in this website
http://forum.xda-developers.com/mate-8/general/best-easiest-to-rollback-to-emui-4-0-t3507399
You first need to dload the update.app from the roll back package. For me the one from Russia work (you can try all three to see if one work). If any of the three rollback update.app work then you can use dload again the update.app that works before you install nougat. After that the phone will be locked. You need to unlock it again if you want to install twrp. You should be able to recover the phone as long as you can use dload and enter into fastboot mode (keep pressing the power button until it turn off then press the volume down at the same time connect it to the PC. If you can shut it down from the recovery menu, it will give you more time to do this).
This happened to me before and I used this method to recover the phone. For me the rollback from Russia works and I can dload back to L09C432B320.

[Guide] Fix for boot-loop and bricked Honor 8 (probably others too)

The reason I'm making this thread is because I was trying to root my Honor 8 and things just didn't work out in TWRP. Rebooted my phone and I realized I had bricked it since it would not boot after 10 minutes. Solutions seem to be scattered throughout different threads so here's guide for when you're stuck in a boot loop or you bricked your Honor 8.
What you'll need:
1. The firmware currently you are on. @Coolyou posted a guide for a firmware finder. Here is the post.
2. SD Card
What to do:
Step 1.
Download the correct firmware. It will be a .zip file.
Step 2.
Create a folder called dload in the root of your SD card, not your internal storage. Copy the .zip file the folder and unzip it or unzip it else where and copy the content into the dload folder
Step 3.
Power off Honor 8 (if possible, sometimes it'll auto boot up when forced shutdown)
Step 4.
Make sure your device is not plugged into a computer as it will load into something else.
Hold Vol+ & Vol- & Power. It will being to install the firmware from the dload folder if done correctly. If it instantly fails that means you downloaded the incorrect firmware the device is already one.
You're done! However, if your device does not go past the startup logo within 3 minutes proceed to step 5.
Step 5 is probably necessary as everytime I've bricked my device, I've had to do the next step.
Step 5.
Power off. Hold power and Vol+. Once in Recovery mode (not eRecovery), clear cache and format your device. Once done, reboot.
Ta-da, you're device is now back to normal.
Unfortunately, I cant seem to get to the part where it detects my dload folder and installs from the UPDATE.APP file. My phone keeps auto restarting whenever I try to turn off, and since bootloader is locked, I cant flash any images. Every time I hold down Vol+, Vol-, and power button the phone just vibrates twice and goes to the blue honor boot logo. I have successfully managed to get to the Fastboot menu by holding down Vol- and power button, but this menu is useless as bootloader is locked. Is there anything I can do?
Let go off the power button after the first vibration. Also make sure your phone is not plugged to a pc. With pc connected it boots into eRecovery instead of recovery. Good luck!
Edit:Also the guide does not make it 100% specific but the dload folder on the sd card needs to have the update.app file right inside it. If the structure is sd\dload\folder\update.app it also won't work.

Add me to the list, two soft bricked Honor 8's. Once I made the jump to Nougat and installed the Nougat version of TWRP 3.0.1-1, I started having issues. So, I tried to downgrade to FRD-L04C567B150 from FRD-L04C567B320 and had big problems installing B150. Always getting unable to load /data Has to be something to do with the new data structure of Nougat I have a copy of the full stock rom of B150 and B162 and have wiped the phone. I am trying to dload full B150 from SDcard but will fail immediately and says Wrong Version. I can get to fastboot and ADB. I also tried custom ROMs but that wont work because they need the basic Nougat structure to work from. I don't have a clue how to proceed seeing that I can't even wipe the phone and install a Full stock ROM B150 or B162??
Any help would be extremely appreciated.

UPDATE : It freaking worked!!! After an entire weekend of hair pulling and going way deep into Nougat and MM trying to find the cause, it was a simple Full ROM B162 that I dloaded and three fingered from the SD card (of course it has to be the exact ROM for your phone such as FRD-L04C567B###). WOW, two phones are back. I'll stay at FRD-L04C567B162 and like it.
Lesson Learned: When you try to do an eRecovery and the Honor 8 starts downloading new firmware from the internet it creates a new folder on the sd card called something like HwOC. In that folder is stored the new firmware that erecover plans to use on the recovery. IF this HwOC folder is present and you try to do a Full ROM three finger install with the B150 or B162 firmware in the dload folder, the recovery will stop and say something like invalid version. To fix, remove the HwOC folder so that only dload is present, now do the three finger start and the firmware will install without error. Worked twice for me.
Hi, my device is still not booting up after installing the matching dload firmware on my device from the honor 8 website (FRD-L09).
Is there still anything I can do to maybe get this fixed?
I created a nandroid backup of all partitions that I were able to back up, but even rolling back all partitions did not make it boot again.
Sadly, I am not able to get the device into e.g. fastboot mode anymore because it is not booting anymore and therefore cant get an adb shell on it.
I can still enter recovery mode, but when trying to boot it just stays at the blue screen with the white "honor" text after the short boot animation with the 3d text
Hi,
my phone keeps entering eRecovery and my PC does not recognize it so please how can I access it to install files. I think I have installed a wrong boot.img and recovery.img version of firmware.
Please I need help.
Thanks

Bricked my phone, help me recovery files please!

Hey guys, my phone d802 just wont boot, it powers off mid boot, its not even a bootloop, I've tried everything and it just doesn't work, the only thing I want at this point is to recover my files cause I already got a new phone, here's what I've tried and failed:
1) Getting into recovery: I have TWRP installed I just can't get into recovery, I tried all the possible button combinations to get into recovery and no one works. The VolumeDown+Power (wait for LG logo) - release - press both Volume Up and Down -> gets me into the factory reset setting, but from here if I wanna proceed I have to delete all user data, which is exactly what Im trying to recover, so this wont work for me as I dont wanna save the phone just the files, some people say you can press power button 3 times from this screen to get to recovery but doesn't work for me.
2) Download Mode: I can get into download mode but then it says "Firmware Update" "Do not unplug the USB connection until blabla..." but it stays at 0% all the time. My pc recognizes the device but doesn't allow me to access files and ADB doesn't work from here, the LG Tool can upgrade the phone to OG firmware but the phone doesn't have enough storage for the update, so the tool prompts me to delete files, which I don't have access to, so im screwed.
HELP! I just need a way to get into TWRP so I can transfer my files to the PC after which I dont care if the phone explodes, someone help me!

That's not correct. Don't worry. After pushing the factory reset you can confirm it and the phone will boot into TWRP.

It just boots TWRP and nothing more. The reset will be skipped. I know the phone says it's going reset itself but it won't. Normally the factory-reset button combination opens the pre-installed recovery which performs the reset. But it's gone since you flashed TWRP. The factory reset can now be done with TWRP.

VNS-L21 bootlooping after opening the phone?

So, i have a phone that was overheating and of which the fingerprint scanner wasnt working.
Opened it to see the sensor, which turned out to be disconnected, and changed the thermal compound as the one present was baked.
After that, the phone got stuck in a bootloop and im a total noob as far as flashing roms etc goes.
It enters erecovery, but i get the package error.
I have an sd card and tried tried the dload method with a vns-l21 rom - i simply pasted the dload folder and tried installing that, install was supposedly complete - still bootlooping.
Could this be a hardware problem, or can i do anything with the software?

Hello,
try to do a factory reset.
Reboot to e-recovery and do the reset.
Reboot again in e-recovery ( if needed ) and do wipe cache.
Reboot system.
Let's see what happens... :fingers-crossed:

Hi, now i'm wondering which firmware you
tried to restore.
I think it should be the same or newer ( but always android 6 ),
because it won't work with dload method on android 7.
Do you know what was the firmware your device was running ?
( the complete firmware ; ex. VNS-L21C432B160 )
