I think you should download firmware for your mobile and flash it.Put the firmware in sdcard/dload/update.app.Now press insert sd card and press vol+ vol- and power button.
Install firmware and also go to recovery mode and wipe cache :highfive:
Hope this works !!

Thanks dear. It worked.

Hi, I have the same problem and I followed your instructions but while the new firmware is installing from the sd card, the phone shut down.
It seems like it has no sufficient power to finish the operation. In fact I tried to plug the phone to charge the battery and that don't work...at least the led is not on (but I'm pretty sure it's not charging).
After that the only things I can do is to power on again and see the boot loop.
Any idea on how to solve?
Thanks.

Shutdown or reboots? The op said that was a G510 and this is the P6 forum
Probably you have the recovery corrupted, you need to reflash stock recovery again via fastboot
THIS IS FOR THE Ascend P6, NOT for the G510

Shutdown. Then if I press the power button or simply I plug the phone to charge the battery, start again to bootloop.
Can you please tell me how to do?

It happens the same to me, but I don't know how to do.
I'm a newbie and I'm not familiar with this command...could you kindly explain what I have to do step by step?

I posted you fastboot noob-friendly tutorials
1st you need fastboot installed and P6 and fastboot drivers
Asumming you already have downloader the image and you are in windows, open a cmd promp and navigate (using cd command) to your fastboot directory, place recovery_original_flashable.img in this folder. If your phone is shutdown, hold vol- and plug the usb cable (if it's continuous rebooting, hold vol- and power button until phone reboots and kernel logo come up)
Type on the cmd promt: fastboot devices , if you see under devices attached, ??????????? or numbers and letters, your phone is connected into fastboot mode
If you don't have this, check if the drivers was correctly installed.
With the phone connected in fastboot mode, type in the cmd promt: fastboot flash recovery recovery_original_flashable.img
After this command finish, type fastboot reboot and enter into the default recovery and try to update the system
I not guarantee the exit of this operation, this solved my problem, but maybe yours not. If you aren't sure, ask here or send phone to your repair center

I am using Huawei G 510-0200 in Pakistan. I had rooted my cell phone and was converting a user app into system app via Titanium backup. The process was taking long time so force closed Titanium Backup app. This caused phone crash and it restarted and hung up at huawei logo.
Now i tried factory data reset and clearing cache in Power and Volume + key mode. It did not work. I tried applying update (two different roms, one custom pakistani rom and other was normal g510-0200 rom) in the same mode but it shows installation aborted.
I tried Forced Firmware Update mode too. I placed update.app file in the sd card and restarted cell phone by holding Volume+, Volume- and Power key. In that mode, it shows unpacking Step 1/2 for a while and then instead of installing, it shows Update Failed.
Error log shows this:
filename = /mmc1/dload/update.app call RCV_MODULE_END_EVENT failed,module = OEMSBL_VER_LIST CMD=0xf,moduleaddr = 0xd2000000, len_tmp=0x4000
I have tried everywhere and I'll be really greatful if you can sort this out for me. :crying:

my phone never came with any stock recovery. had 'factory mode' not recovery when holding those bottons. In factory mode, no option for flashing anything. Now phone only restarts on bootscreen and then on-off. initially tried flashing TWRP just befor bricking phone but adb gave error like this 'partition not support flash and i had already flash a boot.img for b125

b608 version of my phone was a brick was b118 installed, there is a solution?
sorry my poor english, I'm from Turkey, please help, please..

Both of you should try to flash the stock recovery! You can download it here www).androidfilehost.(com)/?fid=23252070760973625 (just remove the brackets) .
Then follow these steps:
1. Put your device in fastboot mode ( > adb reboot bootloader )
2. Flash recovery via fastboot ( fastboot flash recovery recovery.img )
3. Reboot via fastboot ( fastboot reboot )
Afterwards try to reboot to your stock recovery . Then you can simply install over the update.app a fresh Huawei Firmware
Greetings Wisdomseeker

Cant enter recovery or download mode

Hello.
I flashed one KDZ for my country and root my E987. I also used freegee to install CWM (it should unlock boatloader I guess).
The problem in that when: phone turning on, trying to enter recovery, fastboot or download mode I have nothing but a black screen.
The phone is working perfectly.
In freegee I see these options: Backuo and restore EFS, Re LOCK and CWM/TWPR installations
What can be wrong??

In Optimus G (E975), should turn of phone completely (press power button for 10 seconds), then press vol up + power to start phone in bootloader. Then press vol down twice and then power button to start recovery.

I tried again but nothing but a black screen

So, if you can even access to your bootloader with vol up + power , you can connect phone to PC and flash a recovery image file via fastboot adb. (put your recovery image file in fastboot folder and then open a command prompt in that folder and type:
Code:
fastboot flash recovery recoveryfilename.img
Also maybe on your black screen you can do this.
If not, disconnect phone from PC, turn it off, press vol up + vol down together and connect USB cable, you may see download mode. if you see download mode, following method may help, but I'm not sure about E987! I did this on my phone E975 and it works: http://forum.xda-developers.com/showthread.php?t=2249500
Please consider it may remove all your data including system, userdata, sdcard , etc.
Good luck friend

Your welcome
If you could flash kdz means you can access download mode so you can try that method I've said.
Also you can download recovery images from following links :
CWM: https://www.clockworkmod.com/rommanager
TWRP for Optimus G (Sprint) : http://techerrata.com/browse/twrp2/geehrc4g

Your welcome say thanks to autoprime that makes tinybin
Please remember that after tinybin you may see black screen and can't boot android. But fastboot and recovery should work and you can push a flashable zip ROM and flash it through recovery.

P6 bricked? Stuck on Huawei logo

Hello,
my problem is after trying to revert back to the stock rom I messed things up and I can't get back to fastboot mode.
But I will describe what I did. First thing I did many weeks ago was the installation of cyanogenmod 11 KitKat on the P6.
All worked fine except for the high power consumption. Because of that I decided to switch back to the stock rom.
To do that I have made the following steps.
1. I downloaded the Jelly Bean firmware from the official huawei website. (I can't post the link since I'm a new user)
2. I used the download extractor to extract boot.img and recovery.img
3. I flashed them via fastboot
4. I prepared a SD card with the update.app in the dload folder
5. booted the phone with volume buttons pressed. Update process started but failed. There was no error message only a huge FAIL message.
6. After that I switched back to TWRP recovery what worked fine
7. I build a flashable zip file with the update extractor of boot.img, recovery.img, system.img, cust.img, userdata.img and flashed it via TWRP
8. Than I realised that I mistakenly included the recovery.img which overwrote the TWRP recovery
Now the phone always starts to the huawei logo also when starting with volume buttons pressed. I can't access the fastboot mode anymore.
When shutting it down it reboots instantly.
My questions are the following.
* Can a corrupted recovery block the access of the fastboot mode or any mode to access the phone via USB to flash a new recovery?
* Are there other ways to reset the phone?
* Was it a problem to take a Jelly Bean stock rom after a KitKat installation?
* If the phone is bricked, do you have any suggestion what to do with it? Is it worthless now? Sell on ebay? Hope this is not necessary.
Thank you so much!

When you say its bricked does that mean that it gets stuck on huawei ascend logo? If thats the case than you should be ablr to enter fastbboot since thats the sign you are in bootloader mode.

Well that is what I thought too, but I can't get a connection via adb or fastboot.
"adb devices" lists nothing. When connecting the phone via usb to the computer there is no log entry generated on the computer like it's the case with other usb devices.
I tried different usb cables. I'm unsure how to be really sure whether I'm in fastboot mode or not.
Before flashing the zip everything worked fine so it's very unlikely to be a driver issue or something related to the computer I think.

i have the same problem and i cant communicate with the device in any way but what happen to me that i download a wrong recovery img.
if someone can help please

i fix my phone and get it back to the stock recovery ::victory:

Can you please share how you make it? I have the same problem...

I fixed it by replacing the motherboard using a very detailed tutorial on ifixit.
The P6 is not build to be repaired by the customer but with the right tools it was ok.

I turn the phone in the debug mode and flash the stock recovery back you enter the debug mode by press and hold on the volume down then after it the power for 10 sec. after you plug the phone to the computer via usb then download this file: 4shared.com/rar/9HO06Lpjba/p6_stock_recovery.html
and then unzip the file then open by order
1- adb-windows if you have windows
2- fastboot-windows
3- install-recovery-windows
and restart the phone and you have the stock recovery back
