Stuck in RESCUE MODE screen, please HELP ME!!

Hi all!!!
I'm screwed!! :crying::crying::crying:
I think I bricked the phone!
Please help!!
Backups files I already have
A-WRP is correctly installed and I made a full nandroid backup.
B-I have a full partitions backups made with Partitions Backup and Restore App (Root access required). I backup all the partitions, all of them in raw mode. All the files are *.img ready to flash with fastboot.
C-I have a full B132 ALE-L21 stock ROM that was working perfectly before.
The problem
1-adb is not recognizing the device
2-fastboot is not recognizing the device
3-I cannot enter TWRP
4-Huawei EMUI 3 buttons (volume up + volume down + on/off button) function doesn't start neither (I'm trying to force the update to B132 ROM)
5-The phone enters directly to Rescue Mode and says:
error! Func NO : 8 (hifi image) Error NO : 1 (Security verify faild!)
{
"lightbox_close": "Close",
"lightbox_next": "Next",

}
So the phone is still working and I got this RESCUE MODE screen but I can't do anything when this screen is displayed.
Any idea? What can I try?
Please, I really need your help, anything you can imagine to try please, let me know!!!
Thanks in advance!!!
Update:
Finally I was able to enter in FASTBOOT & RESCUE MODE following this procedure:
1-Turn off the phone
2-Connect USB cable to computer but NOT to the phone
3-Press the volume down button and hold It
4-Connect the USB cable to the phone
5-Ready, the phone will turn on automatically in this mode (DO NOT press the power button)
So, now I have fastboot but I CANNOT flash the f.....ing HIFI partition
I tried:
-fastboot flash hifi hifi.img --> command not allowed
-fastboot flash radio hifi.img --> command not allowed
-fastboot flashing unlock --> command not allowed
-I tried to enter recovery mode. I have TWRP installed, I can also flash It again with fastboot, everything good but can't access It after that!!!!
-ADB is not working
-I flash a B052 ROM, then put B132 Update.app file in SD Card root\dload and try to force update by pressing volume up + volume down + power, nothing
-I flash the B132 ROM again , then put B170 Update.zip file in SD Card root\dload and try to force update by pressing volume up + volume down + power, nothing
-I try fastboot update update.zip but It says no android-info.txt nor android-product.txt
-I try to create a flashable .zip file for fastboot but It requires .sig files for the boot, recovery and system partitions
-HiSuite open ups automatically on the computer but can't connect to phone, the phone is not recognize by HiSuite but in windows says Marshall London Bootloader Interface. I can change that to Huwaei HDB Interface, Android ADB Interface, etc. etc. in device manager. A couple of times in the phone screen refreshes saying "Rescue mode enter.." but no way, HiSuite can't connect.
I tried lastest HiSuite version v2.3.55.1 and v1.8.2.206, nothing.
So, I have fastboot, what else can I do? Can somebody help me build a .zip file flashable with fastboot?
Is there any other fastboot or tool (I tried mfastboot too) that may allow me to flash HIFI partition?

3) Connect as described above to enter FASTBOOT & RESCUE MODE
4) fastboot flash cust cust.img
5) fastboot flash recovery recovery.img
6) fastboot flash boot boot.img
7) Disconnect and power off.
8) Hold down Volume+ AND Volume- AND Power until the phone enters EMUI system update mode and stars update from the SD card.
After a few minutes: Up and running.

First and foremost, this is P8 Lite section of the forum.
Did you followed unlocking bootloader procedure for P8? Be sure you have unlocked bootloader, otherwise do it again and retry to flash those 4 files extracted with "Huawei Update Extractor" from FULL APP ROM image specific for your P8 GRA-UL00.
BTW, I have used Fedora Linux v23 to make all the Android moves, never Windows because it fails big time. +1 for Linux :good:
Sorry mate, I don't own a P8, but a P8 Lite. Cheers.

I have the same error How can i fix it?

UrgenT pls help! Huawei p8 lite stuck in logo scr. Phone is new and its locked by net

The phone is brad new i tried to return to them they recejeted saying that he was droped in water but it diddnt..i tried to fastboot and rescue but phone locked cant do a thing..someone pls help so i can prove they dont know how to fix it

You need to try to go to fastboot.
Plugin your phone to your pc.
Best way to try is to first hard reset your phone. "vol up + vol down + power button" for 10 seconds or longer (until its restart)
Then try to go into fastboot by holding down the "vol down + power button" for 10 seconds or longer (until in fastboot)
When you are in fastboot you need to unlock first your bootloader and then you can flash stock firmware.

my huawei p8 lite stuck at boot logo, but i can access twrp recovery, fastboot etc, i guess had flashed it all along with internal memory.. plz guide me how to flash a rom.

Everyone, I made this to go from the start. Follow this guide (also in txt form)
It's gotten to this. You've tinkered with your phone and it's got into a bootloop, also known as a softbrick. Have no fear though, for software problems are much easier to solve than hardware issues. If you have the latter, pray and get in touch with the place you bought your phone from or Huawei themselves. Let's start booting.
Yeah, you could use the numerous scripts in XDA to automate some stuff, but you won't learn much that way. I've found that a) adb and fastboot are really easy programs that Google has provided us with to solve issues/develop and b) their knowledge helps with problemsolving for Android in general. It's good to know your phone. That's the open nature that iOS cannot achieve.
1. Getting the SDK Platform Tools (adb, fastboot e.t.c.)
You can always get the latest SDK Platform Tools .zip by clicking on the link for your OS: Windows, Mac, Linux.
Extract the .zip's contents in a folder. (I trust you know how, even phones can do it nowadays... Anyhow, you can get 7-Zip for Windows, as the built in zip manager is limited)
2. Using the SDK Platform Tools
You give commands to adb and fastboot though a command window.
You have 2 choices. You can either:
a) work from the folder you extracted the sdk tools in (I have them in D:\Portable\platform-tools).
You'll have to do [Shift] + (Right click) > "Open command (or PowerShell) window here"
or
b) edit your PATH environment variable, so you can open a command (or PowerShell) window anywhere you want.
Call the program by name to give commands (e.g. adb <command>)
3. Getting into fastboot/bootloader mode
You can do that in 3 ways:
a) Shut down the phone. While holding VOL- (down), connect a USB cable that is plugged to a power source (usually your PC, since you are planning to use the fastboot program).
b) We'll use the adb utility.
You need to enable USB debugging for this. After that you can refer to "chapter" 2.
Type
adb reboot bootloader
Click to expand...
Click to collapse
and press [Enter].
c) Reboot into a custom recovery like TWRP and go to Reboot > Bootloader
4. Flashing the stock images
Here's the part we care most about, to get out of the bootloop.
If you are truly in fastboot mode, with the green android dude (his name is Andy) and the white background then the command
fastboot devices
Click to expand...
Click to collapse
should return your device's serial number. Then you can go ahead and flash the 4 needed partions from the stock ROM with fastboot.
First of all, you need the 4 .img files for boot, recovery, cust and system.
You can get these as follows:
This page lists all the Huawei Firmware for the ALE model, aka our P8 Lite (Thanks @persona78 for the link, see here). You can translate to English with the Google Translate toolbar on the top. Find a firmware package of type FullOTA and click on the update link to download the zip update file. Inside that zip is the UPDATE.APP file we need, so extract it somewhere.
Use Huawei Update Extractor to extract boot, recovery, cust, and system as .img files.
Open a command window in the folder with the files and rename them accodingly if you wish (e.g. 06.boot.img -> boot.img)
Then you can flash them in fastboot mode by executing these commands 1 by 1. They're pretty self-explanatory.
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
Click to expand...
Click to collapse
That last one may take a bit. Then you can do
fastboot reboot
Click to expand...
Click to collapse

@JpegXguy
fastboot mode, remote command not allowed, I cant start on system to enable USB debugging, fastboot edl doesn't work, so what can I do?

[GUIDE] How to upgrade from Marshmallow B510 to B521

It's a pretty straightforward guide. Just follow the guide carefully and you'll be in no time rocking with B521.
This guide is divided into 5 sections. Follow all sections in the order illustrated in the guide.
Optional Step (Recommended) : Flash Stock B510
It is generally a good idea to start from a completely fresh base. Although not necessary, you will however, loose all your data and apps. Backup what is important before following. ​
Flash Stock Recovery (see Step 4 below)
Download B510 from here: https://mega.nz/#!NYgUFYLA!wEEf0f3w_6wxbzr9TYTvTquGBUhsMmRG53G8RSp2xMQ
Copy the Update.APP in the downloaded B510 ROM to dload folder in the root of your external SD card.
Power off your device.
Hold Volume Down, Volume Up and Power buttons simultaneously until you see the Honor logo. Your device will now automatically flash the whole Update.APP
Step 1 : Flashing Custom Recovery (TWRP in this case)
If you are already on TWRP, then skip this section.​Before you follow make sure you have installed Huawei HiSuite and ADB/Fastboot Tools. If not see the links below:
Huawei HiSuite: http://consumer.huawei.com/minisite/HiSuite_en/
ADB and Fastboot: https://drive.google.com/open?id=0B0LG0AQ4V9FpcXRmV1BmRk1Ta1k
Extract the ADB and Fastboot zip to any preferred location.
Instructions
Download TWRP 3.0.1 Recovery. Head to this thread for download links: http://forum.xda-developers.com/honor-4c/development/recovery-twrp-3-0-0-0-huawei-honor-4c-t3349495 Copy the downloaded recovery to the folder where you have extracted ADB and Fastboot tools.
Power off your device.
Now while holding Volume Down button attach your device to computer via USB cable. Your device will now automatically switch to Fastboot mode.
In the folder where Recovery and Fastboot tools are present, hold down left shift button and simultaneously press Right mouse button. In the dropdown menu, select Open Command Window here.
Switch to the Command Prompt window and type:
Code:
fastboot flash recovery recovery_name.img
Replace recovery_name with the downloaded recovery's file name.
You have successfully installed TWRP :victory:
Step 2 : Enable Local OTA Update option in Marshmallow
In Marshmallow, Huawei has removed the option to flash OTA updates and Update.APP through the Local Update. Lets get that option back!​Credits to this section goes to OXALIS at 4pda.ru for making the patch to enable Local Update option in Huawei Update app.
Download the Huawei Update patch from this link: https://drive.google.com/open?id=0B0LG0AQ4V9FpUXUybmFZeTVXNDg Copy it to either your device's internal memory or a SD card.
Power off your device.
Hold Power and Volume Up buttons simultaneously to boot your device to recovery.
Install the zip downloaded in the first step though TWRP.
Step 3 : Removing Root
If your device is currently not rooted and is completely stock, you can skip this section.​
Before you follow make sure you have installed Huawei HiSuite and ADB/Fastboot Tools. If not see the links below:
Huawei HiSuite: http://consumer.huawei.com/minisite/HiSuite_en/
ADB and Fastboot: https://drive.google.com/open?id=0B0LG0AQ4V9FpcXRmV1BmRk1Ta1k
Extract the ADB and Fastboot zip to any preferred location.
Removing Root
Download Stock Marshmallow boot image from here: https://drive.google.com/open?id=0B0LG0AQ4V9FpY1lBVF9ubFdOSXM Copy it to the folder where you have extracted ADB and Fastboot.
Power off your device.
Now while holding Volume Down button attach your device to computer via USB cable. Your device will now automatically switch to Fastboot mode.
In the folder where Recovery and Fastboot tools are present; hold down left shift button and simultaneously press Right mouse button. In the dropdown menu, select Open Command Window here.
Switch to the Command Prompt window and type:
Code:
fastboot flash boot stock_boot_mm.img
Open SuperSU app and click on "Full Unroot" in Settings.
Your device is now unrooted.
Q. Why not just click the 'Unroot" option in SuperSU app?
Although that would work as it does the same the same thing described above i.e. replace patched ramdisk with stock backup, if the backup isn't present (such as you made a Factory Reset), your ramdisk will remain patched even though unrooted. It's good idea to revert to Stock boot.img if you ever need to root again.
Step 4 : Flashing Stock Recovery
It has been literally mentioned a thousand times that you can't flash official ROMs and OTAs through a custom recovery (such as TWRP). You have to be on Stock Recovery.​
Before you follow make sure you have installed Huawei HiSuite and ADB/Fastboot Tools. If not see the links below:
Huawei HiSuite: http://consumer.huawei.com/minisite/HiSuite_en/
ADB and Fastboot: https://drive.google.com/open?id=0B0LG0AQ4V9FpcXRmV1BmRk1Ta1k
Extract the ADB and Fastboot zip to any preferred location.
Instructions
Download the Marshmallow Stock EMUI Recovery from here: https://drive.google.com/open?id=0B0LG0AQ4V9FpbldwYWExOGNTUTQ Copy the recovery to the location where you have extracted ADB and Fastboot tools.
Power off your device.
Now while holding Volume Down button attach your device to computer via USB cable. Your device will now automatically switch to Fastboot mode.
In the folder where Recovery and Fastboot tools are present; hold down left shift button and simultaneously press Right mouse button. In the dropdown menu, select Open Command Window here.
Switch to the Command Prompt window and type:
Code:
fastboot flash recovery stock_recovery_mm.img
You have successfully installed Stock Recovery :victory:
Step 5 : Updating to B521
Download the B521 OTA zip from here: https://drive.google.com/file/d/0BxgU9yQssu83NTJ6eFBseS1ET3c/view?pref=2&pli=1 (Credits goes to vit755 at 4pda.ru)
Rename the downloaded zip to update.zip and copy it to dload folder in the root of your external SD card.
In your device, open Settings and tap on Update.
Tap the Menu button and then Local Update
Tap the Incremental Update option.
Your device will now reboot to install the update.
Tada! You're done! (Hit thanks if you found this guide useful)

It worked. Now on B521.
Thanks bro

Can anyone provide the changelog for this? is it worth installing over b510?

Help pls.. After installing the update using Huawei updater, the installation got stuck at around 92% so I had to reboot my phone, but now it's stuck in boot loop... I tried flashing the stock Marshmallow rom but I keep on getting install error on forced SD upgrade... My phone version is balong right now..
Edit: I flashed the stock Malaysian Lollipop using forced upgrade and my phone is working again

Are you sure you're on B510. The boot image has been extracted from B510 Update.APP so it should work on all CHM-U01.

I'm on BalongC52B311, CHC—U01, Android 6.0. I suposed equal to B510. Isn´t it?

The CHC-U01 will not work. You have to manually upgrade to B510 first.
The most easiest method is to downgrade to C636B330 and upgrade to B510.

Finally, B521

Stuck with worst version
Hello guys, I am here in Pakistan. Few months ago I tried to update my honor 4c to MM but as you know MM is not available for Pakistan officially.
Someone at xda gave me a version of Honor 4c Marshmallow which was build B502.
I installed and it had so many flaws, now I am unable to downgrade or even upgrade it to any other version.
My build number is CHM-U01C185B502
I need help to downgrade this to KitKat or upgrade it to MM B521 or latest.
I am so disappointed that even I want to throw this phone away or sell it anytime.
Please help me!

Boot animation or simply mi logo and then vibrating and again rebooting???
If mi flash tool shows successfully done without any errors then
Try this
Roeboot to fast boot and type
fastboot oem unlock-go
I guess it will be fixed

I am stuck at boot animation with the three white dots spinning for ever ? will try to do as you said

I tried fastboot oem unlock-go but i get response: token verification failed and device still stuck on bootanimation

well, i think this caused by relocking bootloader after we flash a new firmware. if that happens, just go in fastboot mode by hold power button + volume down, then unlock it again using mi unlock. reboot it..your twrp is back.
no need to enter edl mode & install twrp again, btw thanks..this is helpful

tips to avoid relocking bootloader, when u want to flash a new firmware..just delete emmc apsbot.mbn file inside the firmware using winrar or etc, or u can use psy-man firmware because the emmc file has been deleted

don't flash official miui from twrp (you better do it in edl mode), but yes you can flash custom miui like miui eu, miuipro, multirom, epic miui etc from twrp. and..after u delete the emmc file inside the firmware which is included on every miui rom, your bootloader will be safe

Probably the problem with bootloader file

not a whole lot of talk anywhere else so i'll try here. i just got my kenzo few days ago, jumped the gun and started trying to get twrp on it. i'm assuming the bootloader was locked. As of right now it wont boot up, its in edl mode maybe... red led flashes and i can upgrade driver to 9008. sometimes its recognized by miflash and when it is and i try to flash stock fastboot it gives me an error. i know thats a lot to take in but i'm trying to cover all my bases. the phone came from overseas so sending it back isnt really an option. any help is appreciated.

Try to boot it again in the full system and from there try to unlock your bootloader.
If you done that, reinstall the software.

How can I unlock bootloader without fastboot? If I attempt to enter fastboot or anything that requires reboot I end up on that screen.

Hmm....
Have you tried rebooting to fastboot using adb?

Hello
tested with the toolkit 0.0.0.12.
to see if he recognizes the phone.
he should at least write your serial number.
if that is the case.
you can use DC-unlocker. to open FRP and can be the bootloader.
just an idea.

Dc unlocker needs cash and it doesn t always work.

I am doubting buying DC,unlocker in case,it doesn't work and I will lose money.... I will try toolkit.

3 button upgrade doesn't work either.

I have the same problem after I tried to relock my bootloader using SRKToolHuawei-STABLE-V1.3-20160619 with my bootloader code.
Have you found a solution?
I can boot back into os b394 after I let the battery run out to 0%
I haven't found a way to repair my recovery and fastboot yet because rebooting into fastboot always get's me back to that first error
Func NO: 11 (recovery image)
Error NO: 2 (load failed!)
Then I have to wait for my battery to run out again
Any help to get fast boot and a working recovery back would be appreciated.

Use Huawei multi tool ,then flash system, custom,recovery image ,
If stock recovery opens then use Dload method

I got stock recovery back with the warning that my device is unlocked. Now I get stuck at 'Your device is booting now'. After some time it reboots and opens eRecovery which I cannot use.
How do I get anything on my phone to continue with dload and which firmware would you advice me to flash if I finally get there.
Should I, if even possible at the moment, choose an older firmware version?
Edit: Would the original service rom help? Found it here https://forum.xda-developers.com/huawei-p9lite/help/original-service-rom-huawei-p9-lite-vns-t3688120 but my build number seems too high as the version I need only mentions b381 and b383 not the 394 I currently have..

Same problem for me
No way to shutdown the phone, someone have solved?
Now I'm waiting for the battery to full drain

Hi guys i ve made mistake because i wanted to update to latest release media pad m3 but i could not be able to boot to stock recovery after i flash recovery img extracted from update.app and second time i flash recovery2.img to erecovery partition and i got the same issue error Func No 11(recovery image) and Error NO 2 (load failed) . I also put the update.app to dload folder on sd card but update system is not starting i press volume up and down and power button at same time but is not working.I tried also with huawei multitool but is not working is not recognize my device. Please guys is any other solution to fix this ?Thank You!

I just fixed after power off device and then press volume down and plug the usb cable to pc and i was able to recognize my device and i have use huawei multiTool to unbrick my tablet media pad m3 and has work.

Almost the same problem, help please!!!
Hi guys someone can help me? I have a Honor 9 lite(LLD-L31). Android version 8.0
I apologize but I'm a new user and i don't have much practice with modding in general.
I tried to install root permission in my device. I get bootloader unlock code by DC-unlocker and installed TWPR on my device.
When i went in recovery the error " Failed to unmount '/system'(Device or resource busy)" rushed, so I tried to format data in order to give partition available. I tried again to flash file.zip but the search was empty so I downloaded a most recent version(3.2.3) of TWPR in recovery ramdisk.
Now if i try to log into recovery mode appear the same error (Error! func NO 11 / NO 2).
I can do everything aside going in recovery mode. How can I resolve it? Is it possible to reset to factory settings and try again?
I hope I have explained well the problem.

Could you write down the steps you took to get back in fastboot for me? I'm having troule geting there myself after draining battery.

I fixed it after nothing else here worked.
So this is mostly so I dont ever forget the solution again, but also to possibly help others.
I also have to say that I had the problem with an P8 Lite, but all my problems matched almost exaclty, so It might help you too.
And a third disclaimer: I have no idea if you can flash the stock firmware without having the bootloader unlocked.
If you dont have it unlocked, try this wonderful updated guide: [Links are disabled for me so google this: "Droidhunter unlock huawei bootloader" and pick the article by droithunter.com]
And yes DC-Unlocker, suprisingly actually works (at least for me) and buying their bootloader unlock code was worth the 4 bucks.
So here is the solution:
1. Somehow, however needed get into fastboot. As I couldn't use the volume/power key combo myself, I somehow force reset the phone, pressing various buttons until I managed to boot into it again. I then used the adb bridge to boot into fastboot (google how to connect adb, then use "adb reboot bootloader" to get into the fastboot menu).
2. Download your phone models default stock rom/Update.app (also google that).
3. Extract the Update.app file.
4. Download and use the HuaweiUpdateExtractor tool and open the Update.app file (google again helps).
5. Select the "09.recovery.img" entry (the one with the green arrow on the left), rightclick and select "extract selected" and save it somewhere where you can find it.
6. Open your Fastboot console on PC (its often the same as the ADB console used before, especially if you use Minimal Fastboot and ADB, which I would recommend).
7. Make sure your phone is in Fastboot mode (not recovery) and connected to the pc.
7.1 Make sure your bootloader is unlocked. It might work with a locked one because youre just flashing stock firmware but eh might break more. Its worth the 4 bucks to unlock the bootloader first. (and yes DC unlocker looks super sketchy but somehow it actually worked for me and wasnt a scam).
8. Flash a custom recovery onto the phone (pretty much the same way you flash twrp, but instead of the twrp image you use the .img file you just extracted from the Update.app; Also dont try flashing twrp directly, it will probably not work).
The command to do so is: "fastboot flash recovery [filepath to the .img file without the brackets]".
9. Use the command "fastboot reboot".
10. If your phone doesnt boot normally, use the key combinations to get into the normal recovery screen and recover from a file or whatever (other guides should work from here).
Extra Steps:
As my recovery image was obviously so broken that even flashing twrp on top of it didnt work until I flashed the original reovery image, I went into my phones settings and did a factory reset. Directly after I installed twrps (see google) and set it up so it had full control. Afterwards I rooted and installed LinageOS cause frick EMUI rn).
Hope this helps anyone. If you have any questions feel free to ask me.
