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?

My problem was that when into the original recovery, after a few seconds, phone reboots and back up to kernel logo
The full command for flash is: fastboot flash recovery recovery_original_flashable.img

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:

[RMN8Pro][Global] Bootloop fix

Evening guys, let's fix the Bootloop of our RMN8Pro if we have installed a menu Recovery TWRP faulty/unsuitable or we have installed a ROM that does not belong to our smartphone.
This method is valid for China to global or Global to global.
NOT FOR INDIAN (sorry about that)
You'll need:
ADB files
Fastboot ROM V10.4.5.0.PGGEUXM
Download both files and unzip them in C:/ADB (if you don't have that folder... just create it)
You will need to rename the file extension of the file <<begonia_eea_global_images_V10.4.5.0.PGGEUXM_20191007.0000.0000_9.0_eea_f796762f8a.tgz>> from .tgz to .rar
Let's go!!
Turn the phone off, turn it on in fastboot mode (by pressing both POWER and VOL- ) and connect the phone to the PC with its USB cable.
Open a CMD command console (in administrator mode) in C:/ADB and type this (press enter when finished typing):
Code:
fastboot devices
If you have the drivers installed and everything goes well, a series of alphanumeric characters will appear, such as for example:
Code:
a6ghfxfv6 fastboot
Perfect, we can go on.
Next we will flash one by one the files needed to revive the phone.
Write the following lines and press enter at the end of each of them (wait for the files to be installed between line and line):
Code:
fastboot boot boot.img
fastboot flash system.img
fastboot flash vendor.img
fastboot flash cust cust.img
fastboot flash recovery recovery.img
When you're done, restart the phone with:
Code:
fastboot reboot
Congratulations, you have your RMN8Pro fixed.

So, this is basically a guide of how to flash the images through fastboot, right? Why not just use MiFlash when we are in fastboot mode?

What do you mean by Authorized Xiaomi's Account?? As far as I know, there're 2 types of Mi accounts we commonly talk here.
1. Normal Mi account: used to unlock BL and this can be used in miflash to flash rom, I've tried 100 times in fastboot, and works every time. I registered this account I guess 5 years ago when I need to request unlock BL on note 3 . As I said above, it needs 2 mins to register.
2. Authorised service account: This is not we can easy to register, It's for Mi service center or developers for repair/develop purposes. If no rec, no recovery, blank screen, it can be recovered by SP flash tool, which will need this type of account. This is also why users in following post looking for unbricking.

I can prove this by my bricked redmi note 8 pro.
I used my mi account to unlock BL, flashed global rom, but I cannot use it in SP FLASH TOOL to restore because my MI account is not an Authorised Service Account

Hello,
I have a nex Redmi Note 8 pro, I unlocked it after I use Ifixit.. to install twrp, the phone was in bootloap, after I tried to flash with fastboot commands. Now the phone is off and I have a black screeen. I can't power it on (vol + or -) does not work. power on no more. It is not recognized with miunlock. No fastboot nor recovery. Please help me how I can do?

At the moment you only can do a deep flashing in EDL mode, and need an authorized account... You need to contact someone with this type of account and flash... ( And give some money...)

Some people are saying they managed to bring to life a phone without rocovery without fastboot mode.search and maybe you find a way. As i remember they said with phone turned off you press volume - and power and you have about 5 seconds to flash. I don't know more details.i wish you success

hello
thanks for your ideas, I can't enter in fastboot mode nor recovery. The screeen is black. When I tried with spflash, when I push together vol+ and vol- i hear a noise, but nothing happens with spflash.
I am trying. I think it is loosed.

as far as I know spflash tool should be ready to flash,. it means with all the files selected, the combination is keeping vol+ and connect the USB cable to PC port, I recommend you search in Google about flashing mediatek devices... Good luck

Literally this guide is really about just how to flash with fastboot instead of Mi Flash(tool which can use anyone with Xiaomi Phone - doesn't require Authorized Service ACC)

I had this problem at the weekend(Stuck at EDL mode - tried to flash with SP tool but without success(needed service acc - brom error)), you can use SP flash tool with authorized service acc - fastest way, maybe there will be some cracked security file in the future as one for redmi 6. Or do battery trick. You are stick at EDL mode and cannot reboot from it. You can wait to discharge your phone(Tooks ~2 day with pushed power button) then connect into computer and when the led turn less bright use vol - + power to get into fastboot or disconnect battery and reconnect with pushed vol - to get into fastboot(I have used this three times because of installing wrong recovery).

Just flash the ROM to make it works again. to enter download mode, connect the phone to PC, press and hold volume down + power key, when the screen blank release power key only, then quickly press and hold volume down + volume up.

ROM or firmware is Operating System like OS Windows 7/10. In Android we call it ROM or firmware. You must install or Flash this ROM on your phone. Download the ROM that match with your device model number like SM-A505F, If you have the ROM you must flash it using ODIN tool. If you are not familiar with flashing then you need some one to do it for you.

well just power off your phone by hard reset method .. which you can easily find on YouTube.. then .. press and hold volume up and down simultaneously for 2 seconds .. ( not more than that) and connect usb when the screen turns on to bootloader unlock prompt, let go of the buttons.. then select unlock bootloader mode by using volume keys as directed in the screen .. then enter download Moda by using volume buttons ... and the try flashing twrp again..
p.s-- DON'T FORGET TO INSTALL SAMSUNG DRIVERS BEFORE DOING ALL THESE!!

Hi,
How long have you been holding the power button? You know this phone takes a long time to reboot pressing power button if it is stuck...
Tried holding power + volume down long enough? At least 20 seconds?
Good luck...

Hey,
Try getting in device manager (assuming you use windows) and see if the device is detected when you plug/unplug an USB cable?
Sorry, nothing else I can really think of at the moment.

Hi,
That means your device is not dead yet. It is soft bricked though. I don't know any way to unbrick this device, sorry...
You can read about: Qualcomm HS-USB QDLoader 9008 on google if you don't know about it.
Good luck...
Sébastien.

Just wondering where you found this command to run
fastboot --set-active=other
Not sure if that caused your issue, but when you get back to bootloader or fastbootd, dont run that command. Get the boot img file ready from the android factory image zip, and when you do get to the bootloader menu, flash:
fastboot flash boot --slot all boot.img
As for your issue, try this thread:
https://forum.xda-developers.com/android/development/guide-fixing-hard-bricks-t3403868/amp/
If you can just get back to the bootloader menu, you will be fine. If you do see that no valid slot to boot, don't reboot, get the boot img flashed first, or you'll run into the same issue.
Do you have a case on your phone? If so, remove it. Sometimes cases prevent the power button to be pressed down properly. Hold power and vol down for 30 seconds. If you still can't get to a bootloader, try the link above.

Hello,
The link you provided is for another device / chipset ( LG ?). If @willli flash his device with those files, he may brick it permanently. Be careful advising people to do things you are not sure about... :good:
Cheers...
Sébastien.

Try this:
- Hold the Power button for 30-45 seconds
- if it turns on, turn it off (vibrates)
- Press the Power and Volume down buttons until you see Start.
- flash the stock boot.img to both slots
- fastboot flash boot --slot all boot.img

At one point when I first got my phone, blueline but pretty much the same, I had to hold the key combination for several minutes for it to start up. It was around 3-5 minutes, so I would just try holding it as long as you can.
