Bricked - Cannot do factory reset, always fails - Mate 8 Q&A, Help & Troubleshooting

I tried flashing old all ROMs possible nothing is working
I am getting the error
cust image mount failure, something like that.
Help me out please
Update: I flashed the B500 beta ROM and it worked, although it is still showing that it is B560 for some reason. Factory reset still fails, no app showing the software update

[SOLVED] Stuck in a bootloop/nothing has worked

Hello all!
I was running stock 5.1 rooted when I rebooted my phone and it got stuck in a bootloop. I've faced this with many Android phones so I wasnt concerned until I tried everything and still have yet to find a solution.
I have tried to fully flash the stock images, use Wugfresh's toolkit to return to stock, format system and data, and even try to go back to kiKat all without luck. The bootloop is still present.
I used the one-click unbrick tool that took me back to an early Kitkat build and the phone booted but everything kept crashing. Screenshots say they can't be saved which is weird.
I just want to get back to stock lollipop and I'm at a loss. Any help is appreciated!
EDIT: I followed the instructions here here and was able to repair my /persist partition.

My advice if you already have not tried clean flash.
Download right factory image from https://developers.google.com/android/nexus/images and rund flash-all.bat. ( if adb is already installed, if not then install it also ) . If after flash you get again bootloop try to boot in recovery and wipe cache only.
Thanks for the response, Mairo. I tried that out and I'm still getting a bootloop. When I try and flash a zip in recovery or factory reset I get an error in mounting /persist and then the script will finish. I'm not sure if this will help diagnose the problem...
That was fast

Hard brick - SOLVED

Hi !
To prepare the Nougat update I wanted to go back to original rom but I'm currently stuck on honor blue screen. I was on CM13 with encryption erase.
For info I was on FRD-L09C432B131
What I did :
Flash the original recovery
Put the dload folder with the full rom uptade.app inside
Reboot with vol+ and vol-
Installation was ok
But at the reboot i'm stuck on honor screen
I tryed to wipe data/factory reset and cache from the original recovery but doesn't change anything.
Every help is appreciate.
Thanks guys.
I unlocked again my bootloader but wasn't able to format custom partition, message : FAILED (command remote not allowed)
I'm not able to erase anything too, same message.
I was able to flash boot, recovery, cust and system. I flash again the rom with dload but get stuck again in honor screen. A Factory reset don't resolve my problem.
I think my encryption is still broken because when I unlock again the bootloader and flash TWRP I can't wipe anything, message : Failed to mount '/data' (Invalid argument). Unable to recreate /data/media folder.
Is there a way to do anything ? This phone is driving me mad..
Thanks !
You need to flash first the rollback update from honor site, then flash b131
I was not on Nougat. Are you sure ?
I'm actually on the same boat. I can't seem to get it working either, I first did the rollback update from the Honor site than flashed the update firmware they had on there. That didn't work. Then I tried going into e-recovery, and try doing that. This say's it was successful, but I'm still stuck on the honor screen on boot.
To be clear again I wasn't on Nougat, were you ? If yes your problem is not the same. Good luck anyway..
Problem fix. I was using an old twrp, the one I used to root the device. I tryed with the TWRP suggest for flashing CM13 and I was finally able to wipe the DATA partition.
After that after flashing the B131 via the dload folder I could boot to the original rom.
Hope my wasted night fighting with my H8 can help someone.
I'm a morron but I definitely hate Honor.

Device won't boot, tried rayglobe, tried fastboot flash, no firmware downloads availa

I have an NXT-L29 (432). I've really loved this phone besides the headaches of modding. I've been doing this for years, am well acquainted with fastboot and ADB. I promised I've searched and read as much as I can, I keep getting dead ends.
I'll try to recount what I've done but I've tried so many things I'm probably a bit mixed up. Was using b180 and and Ephemeral Rom for months, decided to go to b321 for black pyramid. Trouble began. Tried dload method (button method wouldn't work,used dialer), it rebooted back to the custom rom. Went to recovery, still TWRP. Wiped, it booted into stock EMUI. Was still rooted, with kangtools somehow. Tried using supersu unroot, failed. Flashed stock recovery from bootloader hoping to update to nougat (gave up on b321), since then it won't boot and I can only get into bootloader and eRecovery. Tried downloading latest version and recovery, getting package fails. Tried reflashing TWRP in bootloader, shows success but brings me back to Erecovery. Tried rayglobe knife unbrick with extracted images from what I believe is my stock firmware. It completes, I press any key to reboot and get stuck on the 'your device is unlocked and can't be trusted' screen. I let it sit there overnight. Tried relocking bootloader but it can't because of root type. Tried manually flashing cust, boot, system, recovery, which is successful, yet I still get stuck at the 'your device has been unlocked and can't be trusted'. Tried using HRK tool but ADB isn't authorized? USB debugging was allowed before I got locked out. I'm stuck, don't know what else to do. I've thought to download another stock firmware but none of the links in the stock thread work anymore. Any help would be greatly appreciated.
One thing that is really racking my brain, why does Erecovery remain after fastboot flashing twrp?
Somehow got back into twrp, flashed 7.0 files and now running nougat. Cannot get back to twrp for the life of me and it doesn't always boot but it's progress. This phone is crazy.
Hello.
I unbricked my phone few. Weeks ago. Now it's fully fonctionnal. But I still can't boot to TWRP. The only manner I found, it's using srktool to reboot in TWRP... The official manner start erecovery too.
hi friend,have you problem....
help meeeee.
have flash a lot rom with fastboot unbrick
but no star sistem
have rom 192 emiui 4

Bricked honor 8 please help

Hello, today while trying to get back to stock i wierdly bircked my honor 8
I flashed the stock recovery and stock boot img
Then i flashed a rollback package and a marshmallow package which i used for this same thing before.
Now the phone didnt start for a solid 30 minutes and ive decided to reflash the rollback and marshmallow package, but after i flashed the rollback got stuck at the boot logo, not even the stock bootanimation showing up.
The phone doesnt reboot neither in any of the recoveries nor in bootloader.
Any help would be appreciated.

Okay so after all of this i managed to reboot to bootloader and get my hands on one of my previous unlock codes. So now ive got an unlocked bootoader, but after fashing twrp the phone is stuck at the 'your device is booting now' when im trying to get in it
I thing you have flashed the wrong TWRP, check for the latest version or at least the one for your build
uh well, hello there again.
i've tried to do the dload method which failed(i used lots of versions tho none worked)
and i've tried flashing marshmallow twrp, which at the moment, well, it cannot mount anything. no partition can get mounted.
Does any of you guys have an idea of what i could try?
thanks in advance
Does it mean that you have access to TWRP ? if TWRP cannot mount a partition, go into mount section, tick system, data, boot, vendor and then reboot to TWRP again. Then try your previous operation. If it cannot mount data, go into wipe, advanced wipe, and click on format data, then restart TWRP and try again
seems like i somehow broke the partition table, cause it shows every storage as 0 mb and mounting isn't available, cant tick the option. Looks like i will have to find some service center to repair it by my own cost, by the end of the month. Though im giving it around the 25th so i got some more time till then, so maybe i find some solution to this problem.
Hey, so I managed to make the phone work again.
I have flashed boot cust recovery recovery2 and system from the italian marshmallow firmware, then I flashed that same firmware using dload method(tho it failed at 99%)

You tried only once? Maybe you should now try to flash TWRP recovery and restore a backup made by TWRP. I can provide you one but for FRD-L09, not another. Another method would be to flash the rollback package and then retry flashing an EMUI 4.X ROM (dload method for both), hope you'll figure it out
I think i expressed myself wrong.
That was how i got the phone to work.
Oh lol I misunderstood because of the "it failed at 99%" and I thought the phone wasn't rebooting , no matter I'm glad you succeeded

[HELP] Bricked device ? need help

my device is BL-L21 version (EU variant)
I saw this thread : https://forum.xda-developers.com/honor-6x/development/rom-aospextended-6-4-honor-6x-t3935711
So rebranded my phone to indian model to get emui 8 according to this video : https://www.youtube.com/watch?v=onj2Z5eh7Mo
Then flashed this custom askuccio recovery : https://drive.google.com/file/d/1qvIgmlPPJ0amS8-aNEIG3xDKc9tHxrW7/view
Now in custom recovery followed the instructions (wipe system cache dalvik data) but could got errors like "could not mount this" "unable to unmount that"
At the time I didn't know all I had to do was to change filesystem then get back to previous one.
So I went into fastboot erase system, data ,cache.
I also wiped internal storage, which I think was the big mistake I've done.
Then back into recovery flash asop6.4 and let it do it's thing, it got stuck on boot screen for quite some time.
When I got back to it, EMUI eRecovery stated something went wrong and proposed to factory reset device. Which I did but gave an error.
Now I tried
* dload method https://forum.xda-developers.com/showpost.php?p=73954487&postcount=240, download link is dead btw.
after copying dload to /sdcard/ and rebooting with vol+/vol-/pwr down, gives : "software install failed"
* HurUpdater, I have trouble finding the correct update.zip/update_all_hw.zip/update_data_public.zip files. Since I can't boot any rom right now I can't use Firmware Finder app.
I also tried to look into /tmp/recovery.log. deleted it because too big, just wanted the result of HurUpdater but I guess permissions have changed and now nothing gets written to it.
* eRecovery to try to get back to stock and do it all over but it didn't work, which is normal since everything is unlocked in the phone.
device then reboots and goes to eRecovery.
I just want to get AOSPExtended running, what should I do ?
Oh yeah also, beginner mistake : I don't have any backup.
Did I do something wrong to get no answers?
