Which kind of update method did you used? 3bts? Or FORCED UPDATE?
Have you tried to go into STOCK recovery (volume up+power button)? Is it working?
Have you downloaded and put in the DLOAD folder the CORRECT firmware for Ur phone?
Please double check and, in case, better to re-download it (be sure it is the correct one for TL-10).
Then try 3btns again.
If procedure works, it' s always a good thing to gointo stock recovery AFTER UPDATE proceure, and apply a full WIPE CACHE AND WIPE DATA/FACTORY RESET.

Hello Tuddu .
I made a forced update .
The method of the three buttons does not work = more white screen LED flashing amber and green three times ( three cycles).
When I connect it to the charger , it is happening. I fear the worst .

Have you the stock recovery installed?
Does the recovery works (can you enter into recovery properly?). If not, you should try to re flash the stock recovery, of course if the HAM7 is recognised by Windows.
Differently, i fear, it could be an hardware problem...
Sent from my S5+ using XDA Free mobile app

The situation evolved !
I come now to start the phone mode " Fastboot & Rescuemode ." But then I do not know what to do.

Here you could if the bootloader is open, the respective imgs (boot, recovery cust, and system) or flash when closed, flashing with a Huawei HiSuite FW.

can I use fastboot to install : boot.img , recovery.img , system.img .
I extracted the .img from the firmware.

I would still flash the cust.img. Then fastboot reboot and hope it starts. The question is, what your battery still says.
If it does not start, then it is probably a case for the service.

I Flasher cust.img , boot.img , recovery.img , system.img . But it does not start. What can I do more for the mode " Fastboot and rescuemode " ?

You could still try the Huawei HiSuite. Furthermore you can flash a Stock Rom. Much more remains not.

Then I flash a ROMSTOCK using cmd fastboot

Only works with the HiSuite.

I also have the same problem. I wonder if you could help me out also. I've been having these problem for 3 weeks now. Here's the story. I was going to sell the phone to my friend, so I was unrooting and installing stock firmware on it. I downloaded the stock firmware from Huawei website. Flash the stock recovery extracted from the firmware update.app. Put the firmware in dload on a newly bought 8GB SanDisk, and forced update. The update failed saying that the update.app could not be found even tho it is under 'root of the sdcard'/dload/upload.app. So I flashed CWM and flash the repacked update.app using the Huawei Update Extractor. It was fine until I redo the forced update process. EMUI showed up half way and failed with the same reason, it could not find the update.app. I restart the phone and it is bricked.
Condition right now. BL is unlocked.
- Turn on normally: It flashes [Red Green Green Green] x 3 before turning off.
- Turn on with Vol+ + Power to get to the recovery: Same result as turning on normally.
- Turn on using 3BTNs: It shows "HUAWEI Ascend" logo and stays there for 48 hours. Then I figured it wasn't going to do anything.
- Turn on into bootloader with vol- + power works fine. I can get to the bootloader.
What I've done so far. Most are suggestion on XDA forum, somes are from other sources.
- fastboot flash boot, recovery, cust, userdata, and system of 3 different versions of firmware (MT7-TL10 for Global, Chinese, and MT7-TL09 Global). All firmwares are from Huawei website. None of them work.
- fastboot flash CWM recovery. Didn't work. I could not get to the recovery mode.
- fastboot flash many boot.img from custom roms hoping it would at least take me to the recovery. Didn't work.
- bought another micro sd card, which didn't matter since both cards work fine on other devices.
- Try using older version of Hi-Suite that has the restore function. This is the weird part. Hi-Suite would starts itself as soon as it detects the phone in bootloader mode, but it says "Phone is not connected." Unfortunately, this fails also.
I wish there were a way to force boot the phone into the recovery mode other than the button combos. What do you think I could do? I'll try anything. Thanks.

i have same problem too . anyone get working way ??????

[Q] Help! Can not boot

Hello,
I have big problem. I tried to upgrade to lollipop version, used it for one hour and then decided to get back to kitkat. For the procedure I used some tool from killerdogKD which name is MT7-L09 Unbrick (it is a fastboot). The procedure went, phone rebooted and got stuck in boot loop (only logo is showed for few seconds). Now I can only get in fastboot and rescue mode. I've tried to flash stock rom, but without success. Any suggestions? PS. Yes, I now I am jackass and sorry for my bad English:angel:

Stock recovery installed (extracted from official KK ROM)??? 3 button procedure already tried?

Will not work. Are there no going back. He can recover only 5.1.
For the people hanging in Bootllop because they have the 4.4.X Recovery flashed.
Load zip, go to the boot loader and the two flash imgs.
command:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
If both of the 5.1.
https://mega.co.nz/#!DNw13JhK!7ATC9p...G50saLGZG3vKzM
KK is not possible 5.1, just with dload the flash 5.1 again. Is indeed just about the one that has 5.1 Recovery again.
Here read next time.

I have the same problem and probably caused by same thing. But I can' even enter bootloader. When phone was bootlooping, I turned it off. Then I tried to get into recovery (by holding power + volume down), but phone always shut down after Huawei logo appears (shut down with short vibration).
It does not matter when I release the buttons, I also tried the recovery (vol up + power) or the force update mode (vol up + vol down + power).
Is there any solution to this? I really hope so...

Look at my post and Liks.

Thank you Fooox1 for trying to help, but the problem is, that I can't even enter the bootloader (and your steps require that). I think that international Mate7 have different key combination for entering bootloader? Check also this: http://forum.xda-developers.com/mate-7/help/fastboot-mode-t3086531
It is true that even before I was not able to get into bootloader with vol down + power, so maybe there is just different key combination or it is not possible at all...
I think I will try to write to Huawei support.

In the bootloader you come when the power is off and you Vol - holding down, then to the PC. To turn it off properly you must Vol - and Power button until it vibrates.
Key combination is the same for all.

I know, that is what I am doing it. And I already did it with many other phones successfully, so its not like this is my first time.
I am holding down power + vol down
Phone vibrates, I am still holding both buttons
Huawei logo appears, I am releasing power button, but still holding vol down button
Phone vibrates and turn off
I also tried to release power button when phone vibrates, or not release both buttons at all or I don't know what else. Tried 100x times.
I will try to contact Huawei, maybe it is known issue. It should really be same key combinations for all devices.
Thank you.

The Mate mus but this depend on the USB, otherwise it does not come into the bootloader.

Whoa! I did it. Yes, it was connected in USB, but in quickcharge USB. I tried different one and I am in!
For some reason, it did not like the quickcharge USB port, strange.
@Fooox1: but thank you, with your last comment I got the idea to try different USB

Well, I am little bit furhter, but still not working unfortunately. I got into bootloader, I flashed the boot and recovery. Then I was trying to three buttons force update and it is still failing.
I have Update.zip in dload folder on sd card, but update is failing immediatelly...

So now, I started the three buttons update while connected to computer via USB and it is actually doing something. But it is too soon to say if it helped (43%).

can't boot too
I need your help Guy's
My Mate 7 did not start after i rooted the lollipop rom with kingroot. I tried to put back the 5.1 boot.img and the recovery.img. After that i tried to flash the ota 5.1 rom agian with the 3 bottons mode. The phone startet the Update but it get stocked by 90%. I waited ca. 10 min after i just rebooted the phone.

Same here! Help!
must we send in warranty?

So it seems to me, that problem is Huawei. Once, they are using Update.APP and later Update.ZIP, not sure why.
- recovery from 5.1 is working, but it is expectin Update.APP, but 5.1 update is in Update.ZIP, so it fails immediately (with error Update.APP not found). Yes, when you connect to phone to computer, it seems that it is doing something and it will get to 90%. But it is actually doing nothing, you can even pull out the sd card and it is the same. I think it is waiting for some action from computer, but not sure which (I also tried to install HiSuite and do something with it, but no success).
- recovery from update B137 will accept Update.ZIP, but when you try to flash it you won't be able to get in it, it is not working (I also tried B127).
So now, we either need recovery, which will work on 5.1 and will accept Update.ZIP or we need update packed as Update.APP (and yes, I tried to rename it etc.). So actually, our phones are pretty ok, we can get in recovery etc., but Huawei is messing with this different formats for some reason
@Fooox1: Do you have any ideas? Maybe you have another bootloader / recovery image? How did you got the 5.1? Thank you...
Edit: maybe the problem is, that we are trying to run the update OTA (Update.ZIP) instead of full rom (Update.APP)? Is this how it is divided, Update.ZIP is just incremental update, while Update.APP is full rom? If that is the case, we will need the full rom, maybe Huawei can release it?

I have not the problem, but users in our forum. I have the boat and recovery.img from the update unzip, a user has then flashed via fastboot and sin device was running again. For him only recovery was gone after he has the Kang Recovery flashed. The Update.zip he did not need to flash.
Other users have only the boot and recovery.img flashed and then the not unpacked update.zip in a folder (dload) on the SD and these then flashed three fingers method. What also has to work.
Here is still the boat and recovery.img of 5.1.
https://mega.co.nz/#!DNw13JhK!7ATC9pAUID0VyX5N3pQwQLbb_VyuOG50saLGZG3vKzM
And update.zip
https://mega.co.nz/#!vdYlxQIA!P34e3RI-hQT1ZY2WnfOosGmkq2wlr6NViq6ehQuWN5k

I think it may help if somebody will create *.img files from Lollipop, then we might be able to flash it via fastboot (the same as it is in this MT7-L09 Unbrick). I think we will need:
boot.img - ok
cache.img
cust.img
recovery.img - ok
system.img
userdata.img

Can make you yourself. Unzip, when present therein Update.app the extension .app in change .zip and unpack. Now you have another Update.app, this you can unpack the Huaweiextraktor, you've got your files. However, it does not contain all IMGs.
You could try but the resulting Update.app to pack in the dload folder and flash. If so, then the original and encrypted.

Hallo again,
i just called the Huawei Service Center in Germany. They openend up a Ticket for me. They told me to make a factory reset and after that the Phone should boot normaly. I did that, but still the same is happening. The shows the Huawei Ascend Logo 2 times and after that i am in recovery mode again.
The only thing i can do next, is to send the phone to the Huawei Service Center and hopefully i will get it back in 7 Days.

TL-10 no OS

Hi guys..hope somebody can help me to get my phone working again..i had lollipop installed and by accident I deleted the internal memory..the only thing what I can is to reboot to recovery twrp..and then on my pc phone shows up..1 cust drive and 1 internal..which is empty..do you have any idea about that? thanks a lot..please help )))

Download the stock rom for your phone model (tl-10) official one, NOT beta version, better directly from Huawei web site.
Extract stock recovery from downloaded file (by using huawei extractor app).
Using ADB commands, flash stock recovery. Then copy stock rom to sdcard and proceede with 3button procedure.
If any of these operations sound new to you, please use "search" button in these forums.

I have downloaded from Huawei web site 120sp04 firmware. I extracted recovery, flashed with adb commands. Copied the stock rom to sd card, and i am not able to force my phone to start update. keeps restarting. is the a special trick for this 3 button procedure? phone should be off, but from bootloader i cannot switch of the phone. Is it possible that the phone doesn't recognize my SD Card? please advise.

Please check, there' s a command trough ADB (I think adb reboot) wich reboot phone.
Then, someone, has been forced to keep the SD card NOT inserted into the phone, waited for reboot and then (after huawei logo I think, but I'm not sure; please check) inserted the SD card.
Then proceede with local update (forced method).
As for the 3button method, simply press and keep pressed volume up+volume down + power on button. All togheter.
Then the phone must boot automatically into recovery and start the procedure itself.
It i clear: stock recovery MUST be already installed !!!

The only thing what i can do is, to flash recovery and boot from fastboot.zip( http://forum.xda-developers.com/mate-7/help/5-1-to-4-4-2-bootloop-t3132888 ) i guess for L09 version, where i can get to update mode with 3 buttons...all other possibilities are not possible. even if i extract from original firmware recovery and boot images, nothing work..i was going from B125 back to B123 to B128 and B313 when in TWRP i deleted everything. Phone is charging, i can turn it off..OS is missing..is it possible that somebody would make a back up in twrp and i would flash it on my phone? or what version of firmware i should start with? what about sideload? does it help? please advise.

Hello!
I have similar problems, but i have the L09.
Check if you can mount system. Or if you can wipe system, because i can't
Good luck!

YU Yureka with no OS stuck on a Bootloop and unable to enter recovery mode.

Hey guys!
So, i was trying to install CM13 unofficial version, and wiped the system and internal storage using TWRP recovery. I was supposed to install the rom from a zip file i had placed in the external memory card. What i did, was, i rebooted the phone by mistake, after wiping it from the recovery without installing the ROM and now the phone is caught in a bootloop. I know i am an idiot to do that. I tried removing the battery and reboot it in recovery mode using the key combination with no luck. It just starts the boot loop. I tried using fastboot and adb from pc to push files into the internal memory, but my device is not getting detected on the adb anymore (maybe the usb debugging is disabled now?).
What i guess is stopping TWRP recovery from showing up is the lack of twrp/themes folder in the internal memory since i wiped it. But there might be some other cause that i am unaware of. What do i do now? Any help will be greatly appreciated!

Hey! I'm having the same problem with my yu yureka.. Can anyone help me please!

Hi! I'm having the same problem with this post... Does anyone knows the solution of this problem. I'd be really glad if anyone could help me with this..please!

Hey are you able to boot into fastboot mode? If you can....
Prerequisites –
1. Make sure that you have 70-80% battery on your phone.
2. You need a PC and a USB cable to connect your phone to the PC.
3. Flashing the factory firmware will wipe all the data present in the internal memory. So, make a backup of that if you can.
4.Install all the necessary Device drivers.
DOWNLOADS -
1. Download the flash tools from here . http://www.mediafire.com/download/87gfz7mdch188an/Flashtools_For_Yu_Yureka.zip
2. Download the factory firmware from Here (cm 12.1) . http://builds.cyngn.com/factory/tomato/cm-12.1-YOG4PAS3JM-tomato-signed-fastboot.zip
Steps To Flash Factory Firmware –
1. Extract the flashtools zip in a new folder on the desktop.
2. Extract the factory firmware zip in the same folder and make sure that all of the flashtools files are also present.
3. Now, power off your phone. If you are stuck in a bootloop, then pull out the battery and reinsert it. (Do not switch on the phone.)
4. While pressing the Volume Up key, connect your phone to the PC with the help of a USB cable.
5. You should now see the fastboot logo on your device. If you did, leave the Volume Up key. (If you do not see the logo, retry the process.)
6. Now go to the folder where you extracted the flash tools and factory firmware and run the flash-all.bat by double clicking on it.
7. A command window will open and the flashing procedure will start. (Make sure that your device does not disconnect from your PC during the procedure.)
8. The command window will automatically close once the procedure is completed.
9. Disconnect your device and boot it up by pressing the Power button. (Since this is first boot after flashing the firmware, it may take upto 5 minutes.)
Done you should be back on cm 12.1

I flashed the factory image via YGDP tool as well as fastboot. But it boots upto a point and then goes in bootloop. Also if i wipe data/cache still it makes no difference. Also unlocked bootloader and twrp also don't load up. Again goes in bootloop.

Hi, I flashed my Yu Yureka AO5512 Yesterday and entered into recovery mode and selected the wipe userdata option. When it was doing the process after 20min the process stopped all together and My phone does not start at all now. If i press any button there is no response at all. Looks like phones OS and everything is wiped out. How do i go about from here?

Sorry to hear that anyway,
By stock lolipop you mean you had the yureka plus with Volte From factory right!!...if so the twrp might have been for the yureka plus with the cm bootloader which got replaced in the new Devcice

I am facing the same problem and in my case I dont think its an battery issue...I was happily using the CM 13.0 Snapshot Rom since a long time...but today morning when I did a soft reset by going into the settings in my yureka...the phone has gone in bootloop...and nothing is working...using fastboot I even flashed the twrp again and also flashed the CM 12.0 Stock firmware..but nothing is working...after the YU logo it restarts....please help...

I am also facing problem maybe worst
I dont know what wrong I am doing but I am getting "FAILED (remote: unknown command)".
Few info:
1. I get my device ID when I do "fastboot devices" but nothing on fastboot -i 0x1ebf oem device-info".
2. Also for my YU5510A fastboot screen doesnt say' "fastboot" it says "Information do not unplug the cable - Secure Phone".
3. I have red light on, phones keeps rebooting 4-5 times than red light goes off and charging stops.

Ignore that and use other fastboot commands and go ahead, as your device is being detected in fastboot mode.

But when I am executing other fastboot commands it halts the process between with error "FAILED (remote: unknown command)".
I have read about this error and people suggested that I need to get into "Download mode" not "fastboot/bootload". To get into "download" mode I tried pressing "VoulumeDown+Power+Home", but nothing happened, it simply restarted the phone.
Please advise.

MATE 7 not booting

Hi, need some urgent help here.
I was trying to install a custom rom, so I unlocked first the bootloader, then flashed twrp 3.0.2 for Android 5.1 and with it I flashed KangVip rom (porto from honor 6).
Problem was it didn't boot, just black screen.
So I supposed the problem was with the rom so I flashed via fastboot the aosp 6, obviously with same results.
I tried lot of stuff (twrp 2.8.x.x, reinstall stock firmware, restore twrp backup of stock full firmware and so on - I did almost everything I could do) and now I'm with a Huge problem: no huawei logo at start, just a white screen and nothing happen. I have twrp 3.0.2 for 5.1 installed right now but I can't install stock recovery.
Please help me, what do I gotta do?

the ported rom is based on Android 6.0 you have Android 5.1 youk should flash 5.1 based rom..
it's good to flash stock and update official to b560 or b571 depending on which region to have then flash twrp recovery and then flash desire rom..

Thx for this.
But I have a problem, I can't install stock recovery and if I try to flash the .img files extracted from update.app nothing happens.
Also, I still have that problem with huawei logo disappeared and a blank white screen instead.

boot into bootloader and flash stock recovery but if you know what exactly firmware was you have(bxxx) then no need to flash recovery just put update.app to your sd card and then force update three buttons combination (volume both and power) turn off it remove data cable then press these three buttons it'll go in recovery sometime but try two or three times(in recovery turn off device) and try again if that method not work you should flash stock recovery to do so and if it didn't go to bootloader(fastboot) then connect data cable and then press vol- and power it'll go to bootloader in bootloader flash stock recovery then force update your device....

Hope you can help me out here...I had just gotten my HAM7 for a couple of days. Was on 4.4.2 B120, was able to get it up to B326. Just yesterday I attempted to flash up to B331 and it succeeded according to the "local update" option. Then it went on boot loop. I tried doing the force 3-button option and that worked to the point of saying it succeeded and will reboot. Now I'm stuck on Ascend Mate logo. I can no longer get into factory option mode (V+Power), only fastboot mode. Also, I can't do force update no more so I can't try any other "update.app" unless I'm missing something here.
Any help in getting this unit at least back to working condition will be a BIG help. I just received this two days ago.
Thx!!!!

Yes, bootloader is unlocked. FYI, I can't do Vol+ Power or 3-button force. I have no idea what went wrong after the B331 update.app flash. It said successful then boot loop after. I have looked all over the forums and tried everything from flashing C900B300 rollback to try and get 4.4.2 that I started out with, but I really don't know which firmware to start with. The last update.app files I was using was the European variants. Phone was originally locked to Ecuador MoviStar network at B120SP04, then I flashed up to B324 5.1.1. Rooted and then wanted to upgrade to B331 so I unrooted and flashed. Now I'm stuck.

Thank you very much....hope that will solve the boot issue and bring this unit back to life

Alright, so I've given up complete hope that I can get my unit back up and running again. I've tried so many ways already with no success (fastboot/adb, force upgrade, etc.,), and even tried to copy my second HAM7 images (via sdk tools) and to no avail.
The thing I'm trying to understand is where exactly do I start with trying to revive? When I first got this device from eBay, it was apparently still on "MoviStar" Telefonica-Spain network so my network bars showed "R" for roaming. Somehow, I was able to flash it from being on V100R001C00B120SP04a and upgrade to B127>B145>B324 which made me able to use my own service normally. It worked fine and I was even able to root it. Decided to do a last upgrade to B331 and while the local update option showed it as successfully installed, it went into boot loop ever since. Hence, I used European firmwares for most of the flashing. My second mate was on B145 and I was able to get that to B331, which is running fine right now.
ATM, I am ONLY able to do Volume-/Power to get into fastboot.
Doesn't work:
- V+/Power (stock recovery)
- V-+/Power (3-button force)
What works:
- V-/Power with USB for fastboot
*Bootloader is unlocked, but I do believe that after flashing the last firmware of B331, I may have done a factory wipe, which probably reset the USB debugging option as well. So, I'm sure I'm stuck with a device that just might be flashed on the wrong firmware and is factory reset which prevents me from flashing a custom rom or even the stock rom???
Any last advice I would be so thankful for...still waiting on the link for KangVip rom from (fazi2015)
All the best...

Okay, so final result is I'm stuck on a frozen logo now. The twrp bat file again showed success in flashing and rebooted the device, but I'm hung on the "Huawei Ascend" logo. I have to pull the battery to shut it off, otherwise it stays on. So I'm now sure that it's a hard bricked device since I did the stupid thing of factory resetting which probably reset the usb debug...making it almost impossible to flash any firmware now.
Thanks for the help anyways...I really appreciate it. Gonna throw this up on eBay and see if anyone wants it for parts

I know it's annoying but last time I research more and guide you I was have same problem don't give up....

I send you recovery flash in fastboot no need of usb debugging usb debugging need for adb not for fastboot in fastboot flash recovery by your self download it
https://mega.co.nz/#!GRw0CZjQ!iZllDkA6yJeWk7iEA4vEVA94r2nM_YjAuiS8B9IZdm0
then extract the zip go to resource and hold shift and left click then select open command port here then power off device completely boot into fastboot (bootloader) connect the device to pc and in command port type
fastboot flash recovery twrp_2_7.img
after that type
fastboot reboot and hold the volume- button of device it'll boot into recovery if you success then reply..

I've noticed two things when flashing KK or LP. On KK, the phone does a constant boot loop with Huawei logo (on off on off), but on LP the Huawei logo hangs...it doesn't boot loop. Is this an indication or just a fault with both OS?
