Flashed TWRP as boot.img / Now it only goes to recovery HELP ME!!!

Hi people...
Everything was going so smoothly... bootloader unlock... root... some nice root apps... free paid games... and my p8 lite was just feeling so good... until... I flashed twrp with flashify under the name of boot.img... Am I stupid or what?! Now I can only get 2 scenarios... when i turn on the phone it goes directly to twrp. In twrp i get the option to go the bootloader screen... If I choose system it goes back to twrp... I can't get it to start. I downloaded the official tar.gz from emui site but I dont know how can I install it. PLEASE HELP... What should I do in this case?! I miss my baby...
Thanks in advance

You have to restore stock recovery in fastboot mode.

How do I do that?! If I wanted to wipe my phone completely and re-install the OS would be better to do it using twrp or stock recovery?
Thank you very much

Sorry, i misunderstood. If you flashed twrp as boot.img, reflash stock boot in fastboot mode.

flash stock boot.img in fastboot mode
and then flash twrp as recovery
will be like this
fastboot flash boot boot.img
fastboot reboot-bootloader
fastboot flash recovery TWRP.img
fastboot reboot
use the boot.img from stock rom and twrp image you downloaded

Oh no!
Now I made some serious **** to my baby... guess now i'll have to send it to huawei to fix it. I made a full wipe like if it was format c: in computers... everything is gone (i didnt had any personal data) it doesnt have OS even. But when I still had twrp i tried to flash boot.img and recovery.img and now when i start it goes directly to bootloader screen but saying "please update system again" and where it used to say phone unlocked it now says (in red letters):
Error!
Func NO: 10 (boot image)
Error NO: 2 (load failed!)
I was able to get to eRecovery with usb connected but when i choose to download e install the new version it gives me the message "wifi starting failed".
It also does not get any instuction with fastboot. but hi suite starts when I connect it. Strange?!
What do you think? Should I send it to huawei? Or is it possible for me to make it work again?
Also tried UPDATE.APP function and all give me fail message.
I'm going crazy!!!! But I love to mess around with android... To me this is the android essence. Fortunately I have a lumia for when my baby doesnt work.loooool
Thank you all

I don't understand why you don't use fastboot. Everybody told you to use it. In our phone situation, without custom kernel or rom, twrp is for experimentation and you cannot mix things.

Well, you warned me... but sometimes i do these kind of *****... So, in this situation you think it's better to send it or is there way to fix this.
By the way, when I enter huawei eRecovery and I get the option to download the firmware through wifi and it says wifi starting failed, is there any way to make this work? And to fastboot do we need to open cmd as administrator to make it work? Because if Hi suite detects the phone I should also be able to fastboot it right?
Thanks for your patience

Just use fastboot aand flash everything
Recovery
Boot
Systme
Cust

hello I have p8 lite unlocked and rooted, yesterday I wanted to install the TWRP 2.8.7. but I was wrong and I installed twrp for the p8 and not p8 lite.
When I go into recovery mode my phone locks that read huawey, I tried with fastboot command to delete the wrong recovery and install the right of the p8 lite but the result does not change, my phone locks that read huawey
i think The commands that you wrote and that I have quoted are also fine for my case, it's' true?

Hi everyone!!
First of all, thanks to everybody who helped me with this situation.
I now am using my baby again as if it was new. I wiped him completely as i stated before and it was as easy as finding the right firmware (136a) and using the vol down + vol up + power button technique. I put the UPDATE.APP file inside a folder named dload in sdcard using other phone (with my p8 was impossible). After that rebooted the device, pressed those 3 buttons and the instalation started successfully.
I just cant explain how happy i was. I stayed 3 days without it.
After that I have been messing with fastboot so thanks to everyone who made me realize that i didnt need to do all of this, but well, A full wipe is always welcome.
Is there any custom kernel on the way for overclock my baby?

Please explain to me how do I put SOLVED in this thread as my problem is already solved...
Thanks

Yeah finally my phone is working now thanks to you I searched many treads and forums but i cant find a solution. But finally i got an easy solution Thank you again bro.. Good Luck !!!:good::good::good::good::good::good::good:

Just download your firmware version, use huawei extractor to extract boot.img,cust.img,recovery.img and system.img
After that,download mininal adb fastboot copy you files into fastboot folder , enter fastboot mode on your phone and from fastboot folder,open cmd and type these commands:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
After this your phone will boot normally. Once you've done this, copy update.app to your sdcard or internal and install it by local update. Once you've done all this,your phone is fine.

May I know how do you wipe your internal storage? and what if after wiping, im unable to get into recovery mode? does it mean phone is not usable anymore?

SOLUTION
Hello. I'm the bigest mess on androids but i know that flashing stock recovery can remove any TWRP/CWR. If its too powerfull flash stock boot and run fastboot -w.(fastboot -w erases all PERSONAL data)

[GUIDE Step-byStep]RETURN2STOCK/UNBRICK/UNLOCK/ROOT] e.g. STUCK AFTER UPDATE

How to unbrick or get back stock on your Huawei Mate 8. There are many reasons why you would want to do that.
In my case my device (AL10) was stuck at "your device cannot be trusted" after updating from B180 to B321.
First I got to thank acer73 for his software. ajsmsg78 and Kris Chen for their links to the right ROMs.
Also thanks to DarkSilentSC for his help, especially with the L29, great support.
He has a L29, which I don't have, so I'm glad he provides help with that device.
This worked for me on my AL10 to get it back on track, should work on other models too. Just have to find the right ROMSs as according to your model. However, I am not responsible if this does not work for you or if it bricks your phone even more.
And remember: don't forget turning on usb debugging whenever you can!
Unbrick (return to Stock)
1. Find yourself a stock ROM.zip according to your model and extract from the zip the update.app (I used one from a B172 (AL10) Stock ROM, I was running a B180 custom ROM, it worked.)
2. Download the Huawei Update Extractor http://forum.xda-developers.com/showthread.php?t=2433454
3. Extract boot.img, recovery.img, system.img and cust.img with the HuaweiUpateExtractor from the Update.App you find in the ROM to somewhere where you can find them easily
4. Head over to http://forum.xda-developers.com/mate-8/development/rayglobe-italian-knife-t3295526 (You can also do it with fastboot commands, but Acer73's tool makes it easier)
5. get yourself the Italian Knife (btw you probably have to turn off your anti-virus program), extract it in a directory on your PC and start Rayglobe_knife.exe
6. Put the images you have extracted into the folder Unbrick (same directory where you extracted Rayglobe Knife in). The folder was created after you started Rayglobe_Knife.exe
7. Boot your phone into bootloader.
8. In the Rayglobe Knife tool choose Unbrick and choose the option where it says you have placed all the images in the unbrick folder.
9. let the magic work. The phone will restart and it will probably take 15 minutes, make sure its charged enough.
After all that I quickly updated to the latest Stock ROM version, in my case B321, which you need to do if you want to flash later a custom B321. See second post if you want to do that as well or continue with unlocking the bootloader.
Now lets get the bootloader unlocked (for some reason mine was still unlocked)
1. Get Minimal ADB https://www.androidfilehost.com/?fid=24521665358595410
2. Hopefully you still have your unlock code (cause you need it otherwise it won't work)
3. Put your phone in Bootloader Mode (Press & hold power and volume down)
4. Extract Minimal ADB zip and run command.bat
5. Type <fastboot oem unlock xxxxxxxxxxxxx> (where xxxx is your bootloader unlock code)
6. Done
Now lets get twrp set up
1. For that we need minimal ADB again
2. Headover to http://forum.xda-developers.com/mate-8/development/recovery-twrp-huawei-mate-8-t3298567
3. Download TWRP according to your EMUI (For B321 it's EMUI 4.1)
4. Place the image in the directory of the Minimal ADB
5. Rename it to just twrp.img (not necessary but simplifies things)
6. Put your phone in Bootloader Mode (Press & hold power and volume down)
7. Run command.bat
8. Type <fastboot flash recovery twrp.img>
9. Then type fastboot reboot
10. Now you can hold volume up and power until your phone boots into TWRP
11. You need to format data (you'll lose everything on your phone)
12. Done

Remember: don't forget turning on usb debugging whenever you can!
!!!FOR L29 scroll down to DarkSilentSC's instructions!!!
After unbricking I quickly updated my AL10 to the latest version, in this case B321. Should work with all B3xx
1. Head over to Kris Chen's thread (this I used for the AL10)
http://forum.xda-developers.com/mate-8/development/rom-verison-t3324164
Or ajsmsg78's (also AL10 and L09)
http://forum.xda-developers.com/showpost.php?p=66776194&postcount=58 to get the Stock B321
2. Download the ROM and after downloading the zip file, extract update.app from it. Copy the UPDATE.APP to the internal memory of your HM8 in a folder called - dload (you may have to create it). Then press [volume+]+
[volume-]+[power] together to force the update.
3. Voila B321
-----------
!!![For the L29 you should try DarkSilentSC's instructions, which you find below or in post #54 on page 6 http://forum.xda-developers.com/mate-8/general/unbrick-updating-to-b321-t3375934/page6 don't forget to hit thanks!!!
1. Start from stock B170 firmware with TWRP ready
2. Extract BOOT, CUST, RECOVERY, SYSTEM from B321 UPDATE.APP
3. Add firmware .zip file (which contains META-INF folder and UPDATE.APP) and place it into internal storage
4. Make sure internal storage data is fully backed up
5. Delete All Accounts in Settings
6. Go to Recovery, Wipe Cache, Delvik Cache, Data, System
7. Flash that .zip file! (Getting errors is okay at this time) [This is what I didn't do before!]
8. Boot straight to bootloader
9. fastboot flash boot, cust, and system
10. let it boot. Let it proceed with encryption process in chinese and fully boot into EMUI
11. NOW I'M AT EMUI 4.1!
12. Reboot to fastboot and fastboot flash insecure_boot and flash TWRP
13. Reboot to recovery (TWRP) and then flash whatever rom you want to place in!
14. Enjoying it!

Great, was looking for details instructions like that, was stuck at cannot be trusted screen

But you first used different ROM images to unbrick and then tried to update to B321.
really sounds as if your file is corrupted. Would try to download it again

ok i will try tommorow......thanks for help by theway the phone booted but if i flash recovery for root no boot.... very strange....sometimes aloud to flash from boot some times no ohhhhhhh(((
Or something no correct with huawei extractor..... Can you provide extracted files?
Thanks in advance.

So I unbricked with B170 and then tried force flashing B321. My first attempt at flashing B321 ended up getting stuck at 5%. Tried flashing again and it said it was incompatible with the current firmware version of my phone. Any ideas on what I should do next?
Edit: Nevermind. I mistakenly copied the UPDATE.APP from B170 to the dload folder instead of the one from B321. lol
Now on B321. Thanks!

Don't know which ROM you used to unbrick.
But seems that you used an B321 if that worked for you and you have no problems then that is great.
Could mean that wet can unbrick straight with the most current ROM available. If someone else could confirm?

hello, my phone is still stuck.. i tried other cust/system/recovery/boot from other update.app, but its still stuck at: your device has been unlocked... im on l29

Have NXT-L29, downloaded stock L09 file from posted link, placed UPDATE.APP into 'dload' folder which I created, but still hanging at 5%. What to do?? Exactly where do I create this 'dload' folder? Just at 'Internal Storage'?

Bootloader has to be unlocked. You can unlock best with DC unlocker, it's fast and only costs around 5 dollars.
Unless you already have your unlock code then you can unlock following instructions see my first post

Is there a system.img for BTV-W09 (stuck on No OS)

Hello XDA Forum,
I was trying to update my US M3 BTV-W09 to the latest version and rooted and got stuck trying to get the stock image (UPDATE.APP) to load and wiped the device. Now all I can get to is the bootloader & TWRP recovery. Can someone provide a system.img I can flash via TWRP or let me know how I can flash stock back to the device?
Right now, when I put the C100B006 EMUI4.1+Android 6 UPDATE.APP on my sdcard in dload folder, nothing happens past booting to unlocked warning, so the forcible rollback update isn't working for me. Guess what I'm looking for is a base image to flash all the things and start from scratch...
Any help greatly appreciated!

Is there a way to get back the recovery that will allow me to do dload recovery?

Yes. Use huawei firmware finder, download the rom you want (be aware to choose the actual rom you want to use), unzip the update.app; after that - with HuaweiUpdateExtractor_0.9.9.5 - extract recovery.img from that. The next step is turn off tablet, hold volume down, and after that plug it to your pc. After that type in command prompt (be fastboot.exe and recovery.img in the same folder):
fastboot flash recovery recovery.img
fastboot reboot
I hope, I helped.

Thx for the comment, but the tablet still doesn't boot into erecovery or forcible recovery/update

Bricked CPN-W09 Bootloop

Hey all,
After attempting to install TWRP and Lineage on my M3, it seems I put it into a boot loop. I can get into recovery/rescue mode but that's about it.
I've so far tried the dload method as well as this method but can't seem to find the last few files I need! The linked thread that mentions a Huawei Multi-Tool looks promising but the UPDATE.APP file I have doesn't have a SYSTEM.IMG or CUST.IMG file. Does anyone know where I can find these? I've tried flashing just the BOOT.IMG and RECOVERY.IMG files I have, but afterward I'm still stuck in the loop.
I'm not sure what to try anymore to get it out of the loop it's in, I can't get to a recovery. Please let me know if anyone has suggestions, otherwise it looks like I might have to get a new tablet. Thanks!

This issue was fixed by using the Multi-Tool software mentioned previously to flash an older version of TWRP, 3.2.0-0 then flash Lineage 16.0 from there.
