Hi everyone
Firstly I'd like to thank this forum and all the contributors that posted. Without these useful information I wouldn't able to unbrick my phone.
I'd like to share my experience with "Error! Func NO:12 (FUNC_LOAD_IOM3) Error NO:1". and e:could not mount data and "unable to find crypto footer"
My phone had this error in the past and it has successfully unbricked.
This took me two weeks, I've tried every single guide I can find online, somehow I got it to work.
I hope my post will help you towards fixing your issue.
(Its strange for people like you and me still fiddling with our mate 7s in 2018 )

I have a MT7-UL00 with 6.0 marshmellow B561. I was trying to downgrade to 5.1. I was following a downgrade guide and was told I need to card flash (power, vol + and vol -) a B500 update.app rom via SD card first in order to downgrade.
I failed because of two reasons, I connected my USB to my pc when trying to flash it and my SD card was in FAT format rather than NTFS.
After my card flash failed I used HuaweiUpdateExtractor_0.9.9.5 to repack the B500 update.app and flashed it by using TWRP, and this bricked my phone.
(There might be other things I've done in the interim like wipe all partitions etc, I don't remember the steps on how I bricked it)
I start to get Error! Func NO:12 (FUNC_LOAD_IOM3) Error NO:1 and I can not re-enter recovery mode
I rebooted to fastboot mode (power and vol -), and flashed TWRP 2.8.7.0 and pressing (vol +, vol - and power) I was able to get into TWRP.
In TWRP, I cannot do any wipe or repair or reformat, I get an error message "e:could not mount data and "unable to find crypto footer"
I've reflashed twrp-v1-hi3630.img and reformatted the all the partitions and fixed the mount issue.
https://www.youtube.com/watch?v=cvXbzhJEan8
I've then followed the downgrade process to downgrade from 6.0 to 5.1
I've rebooted into fastboot and flashed stock B561 rom using fastboot. (I can not find any stock 6.0 update.app rom)
(After this step somehow TWRP 3.0 stopped working, I have to downgrade to 2.8.7.0, but I don't think you require to do this to complete the following steps)
(Your recovery should be back to stock standard, if not you need to flash your recovery back to Huawei recovery)
Then I flashed B500 using card flash (reformat SD card to NTFS, put dload folder in root path in SD card, unplug usb cable, press vol +, vol - and power to flash)
Then I flashed B351 using card flash (same process)
Then the phone recovered. I was able to boot into the OS with android 5.1.
I hope this information helps you to unbrick your phone.
Good luck.
Will give this a try, am also in that same problem. Hope the phone wakes up

am try to update it with more firmwares but always faild
and try also from fastboot and adb but i canot flash recovery or boot file
so please how can i fix it and make it working like before
thanks
My problem solved please admin close this thread
Please!! tell my how you did it. I have the same problem. Greatly appreciated.
I am just bothered by the same problem for days.
did some research in the meantime...it seems only a few other HAM7 owners ended up like we did.
Unfortunately none of them was able to get the phone back to life, even though it's "just" a soft brick.
bro my problem solved after am leave my phone on charger for 3 hours , before always failed but after recharge my phone for 3 hourse its working and make update with no errors
solved!!
Finally I managed to get the device back to life
Here's what I did:
1. get the latest ROM package for your device - this MUST be the ROM you had installed prior to the crash
2. extract the package with Huawei Update extractor
3. flash via fastboot a) the boot.img and b) the recovery.img (take those file from the extracted folder)
4. get a SD Card and put the update.app file into the dload folder in root directory (you have to create dload folder first)
5. put the SD Card into the device and force update via 3-button method (press Vol +, Vol - and Power at the same time)
6. Update should complete now (if you stuck with 90%, try a different ROM - for me it only worked with exactly the same package I've installed prior to the crash)
- That should be it....Can't tell you how happy I am, after 2 weeks I got my beloved Mate7 back.

Force update do not boot via 3 button method and go directly into rescue mode(FUNC_LOAD_IOM3). Is it possible to get my HAM7 life back?

You're sure you have the correct update.app in the dlaod folder of your sd-card? As I wrote before, for me it only worked when I had the exact same update.app (in my case it was the B324 Version).
But see the steps I've done before, I mean I flashed boot and recovery img - which I've extracted from the update package.
Honestly, I'm not 100% sure what finally solved my problem - I just tried to recall the steps I made.
Hi,
I have a Honor 6 H60-L02
- It was with B811;
- Bootloder Unlocked;
- Tried to install TWRP, it did;
- In TWRP tried to root/intall superuser, it gone wrong;
- Rebooted, it hard bricked, staied in loop in huawei logo;
- Couldnt do anything even turn off it back turn on to logo;
- Let draw completely the battery, tried to connect with Vol+ and connect to pc get fastboot;
- Battery died(Led Red Blinking), removed battery, installed 3 times and it started to charge;
- By fastboot, tried to flash multiple ways recovery, boot, cust, system, it flash all ok, but doesn work anything;
- The buttons combinations doesn´t work any. Just the fastboot access (Vol+ and Usb cable).
Need HELP please
I had a similar problem (on a L04) but I fixed it by flashing 4 images (cust, recovery, system, boot) through fastboot. I flashed B820 since that's what I had before soft-bricking it with wrong root .zip archive. If I were you, I would try to flash B811 through fastboot again, and try to be patient (you can take a look at the logcat, although you need to give it a while. I'm pretty sure you also need to make a factory reset in Huawei's recovery to make it work (well, theoretically root shouldn't touch user data if I'm correct, but I guess you prefer to be extra sure... you may try both with and without resetting it).
And for heaven's sake, people need to stop making the mistake we both did. Please, before flashing ANYTHING, make sure you have a TWRP backup, it will save you lots of time and stress...
Hey guys,
I have an honor 6 l02, running android mm, developer channel. I tried to downgrade to lollipop beta channel by flashing in fastboot recovery, cust, bot and system imgs. When I inserted the sd card with full b535 rom, the installation doesnt start, tried entering recovery and it fails, so 3 button method doesnt work.
I tried changing recoveries, and the only one that works is from developer channel, 6.3.1 and twrp. Installation stops on 5% when using 6.3.1 recovery.
What else can I try, I am desperate?!
i also have the same problem .. boot loop , open up the battery , hard reset . TWRP did & flash all fastboot flash recovery RECOVERY.img SYSTEM.img BOOT.img CACHE.img CUST.img USERDATA.img , put Update.app inside dload folder ( Sdcard & transfer it inside phone) , still unable to install new os. i believe already clear up all data inside the phone , did format it . just pending on changing a new phone only . seek your advise
H60-l12
I have also the Problem.
When i want to Flash the Update.app file, i get always this Screen...

Follow these steps if you are able to get in fastboot mode:
Download your phone's latest firmware and extract system.img, boot.img, recovery.img, cust.img from UPDATE.APP using Huawei Update Extractor tool.
Boot into bootloader mode by switching off the phone then pressing only the Vol DOWN button, and connecting it to PC simultaneously.
Flash recovery first, using this command.
Code:
fastboot flash recovery recovery.img
Flash all other extracted files similarly firing these commands.
Code:
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img
After doing this put that very UPDATE.APP from which you extracted the files in dload folder of your external SDCARD.
Switch off your phone, and press Vol UP + Vol DOWN + Power button simultaneously.
Your device will now get to the full stock firmware.
NOTE: If the manual flashing doesn't works or you get any errors, then first try only the force update method, i.e Putting the UPDATE.APP from which you extracted the files in dload folder of your external SDCARD and pressing Vol UP + Vol DOWN + Power button simultaneously after switching off your phone.
Bootloader is unlocked.
TWRP 2.8.7.0 for 4.4 ( mobopx v2.2 ) is installed but somehow it is faulty.
I have two Nandroid Backups.
Phone was C00B137 4.4.2.
Phone doesn't boot so can't install any of those (UPDATE.APP) method updates. Stuck on huawei Ascend powered by android.
i CAN boot into twrp and fastboot (fastboot&rescue) .
TWRP backup works so i got two backup first one right after flashing the custom recovery, and another after everything wipe and an unsuccessful android 6 flash (B571) (phone booted into a clean 4.4.2 (what it was on) but empty motion control setting. and "update from usb storage" button removed from updater's app (the only way it installed that unsuccessful android 6 update ).
So, What was the dumb move?
That shouldn't happen.. when i selected everything to wipe, after that. Yeah. That's enough go read the rest.
.
.
.
What is it? What are you waiting for?
Why can't install any rom:
1- TWRP Restore does not work (does not find the backup).
TWRP ADB Sideload Probably doesn't work (i connect to pc then click the adb sideload, infinite loading until i cancel on phone. no device detected on windows).
2- Worst part : SD Card Does NOT get detected in TWRP.
The only way to transfer files to phone is through USB Storage (Otg).
3- As mentioned before, all complete updates are .app files. With This TWRP, only zip files can be installed (Which are just as suffix to the os, all are 100 mb, 300, 700mb, what is this? humans update is 1.2GB up to 2.2GB and more.) the TWRP Install works as i tried to install one of those zip update files, obviously unsucessfull (Zip signature Failed or something like this).
References:
The B571 rom i installed (that was finished but after reboot it was still 4.4.2 with bugs) is C432B571 Full OTA( Europe ) from this page.
The Twrp i used is Recovery mate7 mobopx v2.2 update and translate by chudy_85 on same page. number 7:

the adb i use is shift right clicking on platform-tools folder -> open command prompt here. learnt from here. also unlocked boot loader according to that (although with help of honortuner ( https://forum.xda-developers.com/t/info-unlock-bootloader-recovery-root-noob-friendly.3453204/ ) ).
UPDATE:
1--This is the log of when i unlocked bootloader:
2-- ADB WORKED! At least in recovery (not that sideload button in advanced) :
What should i do now? how to flash UPDATE.APP through adb??
Should i first flash stock recovery then through huawei update (key combination) update using sd card The update.APP????????????????
but i will lose custom recovery so if it fail i will truly brick the phone this time. HELP!
no help for me?

In the above picture you can see the Errors I am having in recovery mode.
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
Some say it's emmc chip failure but I read a forum here ( that's for another phone); in that post, someone posted exactly the same errors and he managed to fix the issues. I will post the link to that forum if I found it.

HOW IT HAPPENED
The phone was on charging and I pulled out the charging cable and turned it on and after powered by Android screen this recovery screen appeared out of nowhere. It was on charging overnight.
------------------------------------------------------------------------------------------------
BY FAR WHAT I HAVE PERFORMED
1. I did wipe the cache partition first. - no use
2 Then I downloaded the firmware (2 firmware) and Qualcomm USB loader 9008 drivers and qpst and qpil, after that, I copied the firmware zip files in phone's sd card and tried the " support from SD card" option in " recovery mode ", didn't work, stopped automatically, it was so quick that I couldn't read the errors.
3 Now I tried to wipe data/ factory reset - nothing happened, the process started and stopped automatically.
4 I tried to flash rom on it, ERROR - download fail sahara fail, sahara server fail. Every single time, I changed the versions of flash tool USB drivers, old versions, latest versions, my laptop is flooded with unnecessary versions, it drive looks pretty messed up right now. Zip files and extracted files everywhere.
5 at this point I tried adb and fastboot, adb devices command shows my device name successfully but after that no command works, sometimes it showed failed or sometimes - waiting for device.
Sometimes it keeps saying - *failed to write data 'protocol fault (no status)' *

EXTRA- I don't know if the bootloader is unlocked or locked or USB debugging is on/off.
I WAS HOPING FOR GENUINE HELP FROM ANYONE OUT THERE, THANKS A TON.
Hi, I have that problem of the title. What can it be?
It have TWRP and I did a rollback from Nougat to Marshmallow (Current Build BLL-L23C900B120-log) and after the rollback the problem persists, can't even charge my phone because it automatically boot and well, I tried with a lot of roms with C605 and nothing works. I performed a rollback because after I updated it back then it's build was NDR90M test key and it didn't let me open any banking app because of security reasons. Any solution? Thanks in advance.
Sorry if this is not the right forum. I understand that Huawei Mate 9 Lite is the same as Huawei Honor 6X.
Pls don't flash again B380 or any firmware without the data update.app or you may see the NDRM90-TEST keys trust me next time flash B342

Ok there is still a chance to get working again your device
You will need potatonv (if you got the bootloader locked as user not fblock)
B120log zip and B342 Update and Data update
This TWRP
And Huawei firmware extractor
First recover the phone
I don't know if you really had the bootloader unlocked if you don't you need to unlock it using potatonv with kirin 65x (A) the test point of BLL-L23 is located near the fingerprint conector (right of them) short it when connect your phone to get the EDL and start the potatonv also save your new bootloader unlock code and do the OEM unlock
From the B120 update.app open the Huawei update extractor and extract the recovery and recovery2 images
Put the phone in fastboot mode (put USB and press vol -)
And flash
Fastboot flash recovery recovery.img
Fastboot flash recovery2 recovery2.img
Now take a SD card and make the dload folder and copy the b120 update.app here
Put the phone in dload using the 3 button combo (pwr vol - +) and the update should be installed now
If the process is correct your device will boot as normal with android 6.0 B120Log
To correctly update now the bootloader needs to be still unlocked
Flash the TWRP 3.0.3.0 (newers version directly don't boot)
Copy the B342 zip and this OEM info (not the update.app) to the micro SD (THE INTERNAL MEMORY IS NOT AVAILABLE DURING THIS PROCESS) flash first the OEM info reunlock the bootloader using the fastboot OEM unlock next flash the B342 zip
After that reboot and wait until the system boots complete the device oobe and in the phone info you will still get NDRM90-TEST keys
To fix that you need the B342 Data zip delete in the SD CARD the B120 update.app and replace with the B342 Data update.app
Do again the dload combo and let the phone flash the cust and other info if the process is correct you device info will show the correct compilation instead of NDRM90-TEST keys and safety net should work now (Device certificated)
