Hi,
This should help you restore your phone to working state:

i already have seen some tutorials where butt my problem is connect the phone with pc, when i press the power and volume down the lg gives-me the error i said and the phone turn off, so i don't know how to connect the phone with the computer ...

just downloand open europe v20a flash it with kdz flasher remove battery put usb cable while holding the volume down after you mast have install lg drivers run kdz flasher slect the kdz and press flash put the battery back and leave the phone the program will freeze is normal dont afraid and after when the phone open unlock your booltader first root it and after downloand rom manager and flash recovery through this app but is not touch recovery is normal recovery

Can't this be solveed by simply reflshing recovery?
The phone gets into s/w mode so just type from terminal
-> fastboot flash recovery "recovery.img"(change with name of img file in this case)
Obviously try with a recovery different from the one you already tried with

Error message when starting

was with the original rom lg. and then went instalr the recovery of the cyanogen rom manager app, and then hung up the phone and now the message appears in red at the top of the screen
"Critical Failure: Unable to start Kernel.
Unrecoverable bootloader error (0x00000002)"
and I can not get into download mode to install the original rom again.
and now what do I do? I lost my phone?

you flashed cwm without unlocking your bootloader. re-flash latest jellybean kdz file for your phone using http://forum.xda-developers.com/showthread.php?t=2069723, then read some more about unlocking bootloader, and then start again.

but now I am unable to get into download mode on the phone. is
" Now just hold down vol - key ( hold hold hold dont release !!!! ) and plug the USB cable until you get screen like this :-"
he does not. whenever I do this it only vibrates strong and goes to the screen with the error message. I do not know why that. remember one time it happened to me already but can not remember how I resolved it is possible to even lose the download mode?

Its not possible afaik. Are you sure you are holding only vol - key and plugging in? Dont hold power key!

yes, I'm almost the whole day trying to get into download mode by pressing volume down + connecting the usb. and whenever it vibrates strong and hangs on lg logo. tried to volume up + usb connect. and no download mode. I'm going crazy with this phone. otherwise hesitate to hard reset? or other shortcut to download mode?

hard reset wont help you, as far as i know, you somehow need to enter s/w upgrade screen. did you try it with battery out?

he battery of the same error, and no battery it does nothing, or vibrate, or flash screen, nothing happens

Will I not be able to see my optimus running again? :crying:

it is not possible to load the kernel, what could I do?

Hi Raphael20 and everyone else,
Did you manage to figure out a solution to this? I have the same issue, i.e. cannot start my phone by holding the power button. Not even when people suggest to get to the S/W Update screen by holding the Volume down + plug into the computer.
I got to this error when I tried to do a factory reset. I installed the ClockworkMod Recovery. Then the factory reset via Volume up + Power button gave me the "Critical Failure: Unable to start Kernel" error. I somehow managed to get access to my phone by holding the Volume down + plug into the computer. Then tried to do a factory reset via the system settings of my phone. My phone restarted and then gave me the "Critical Failure: Unable to start Kernel" screen of death! Now Volume down + plug into the computer gives me the "Critical Failure: Unable to start Kernel", no matter whether I have restarted my computer and I have tried another computer. It seems that the bootloader is wrecked.
Does anyone have any suggestions?
Thanks!

Can't unbrick my Lenovo K3 Note (K50-t5)

Dear XDA-members,
please try helping me with my problem before redirecting me to some tutorials. I think I already tried all of them and I even opened a thread in a german forum... noone could solve my problem there, yet.
Here's the deal:
-Bootloop in starting screen
-Stock recovery freezes to on boot
-Vol- and Power leads to "Have been in meta mode, long press the power button and the normal boot"
-Yes, I used the new drivers, SP Flash tool and several ROM's
-Yes I disabled driver signature verification
- In SP Flash Tool I checked "DA DL All"
- My OS is Win10x64
If I load a scatter and press "Download" there appears a red bar with "Download DA 100%" followed by "S_FT_DOWNLOAD_FAIL (4008)". I used Google to solve the problem but no succes...
SO if I try "Firmware Upgrade or Format All", the red bar changes to "Format 0%" followed by "BROM ERROR : S_FT_FORMAT_FAIL (4010)".
By now I tryed 3 different PC's and 2 cables. My father's K3 Note could be flashed without any problems on this PC's.
I hope someone can help me please.

Nonetheless the phone is recognised by the PC itself.

Is anything related to phone or android showing in windows device manager..?
If not then maybe driver problem..
And even after falshing ptocedure its say "factory mode" then maybe it'll light up by adb command..

Device-Manager shows "Portable Devices>MTP-USB-Device".
I don't believe it's a driver problem because I installed so many of them already and I had the same errors in SP Flash Tool everytime.
When I type "adb devices" in adb flashtool there are no devices shown, though it recognises my other smartphone.

I know this is not the topic but maybe atlesst you can read it..
So after doing the first trick of putting the Lenovo S880 into safe mode (or meta mode?), I tried pressing the Volume Up button. But it’s not working. This time I tried pressing the "Power button and the Volume Up button" and to my surprise a menu suddenly appears. It’s the Factory Mode screen menu of the Lenovo S880!
To cut it short, you should choose ‘Clear eMMC’ to reset your Lenovo S880. You can do this by pressing the Volume Up button to navigate the menu. After choosing the ‘Clear eMMC’ option, press the Volume Down button to perform software reset on the Lenovo S880. It will be quick and short erasing the internal memory of your smartphone and will reboot automatically. After the reboot, the annoying ‘locked’ unlock screen will disappear.

Thanks for your effort.
When I press Vol+ nothing happens. Vol+ and Power leads to the meta mode I think (smth in chinese and "Have been in meta mode, long press the power button and the normal boot" appears) as I already mentioned. When I press Vol+ or Vol+ and Power again either nothing happens or the Phone turns off again.
I can't even get into recovery mode becaus my phone freezes at "K3 recovery" screen.

Mi A2 black screen, cant turn on!

Hi guys, my Mi A2 wont turn on anymore. I was downloading PubG mobile and then installed it and while it was being installed my phone was freezing. The screen then dimmed and then turned black. I then tried to reset it (holding power button and volume up/down, only holding power button... i tried almost every combination) without success. When i plug in the charger there is no vibration and no led indication. Back at home i tried to plug in the computer. I hear the sound of the pc which indicates that a usb device was connected but nothing more. When i hold the power button while plugged at the pc, after 12 or so seconds the sound of usb disconnection and shortly after of usb connection is coming. The phone was fully charged.
I use rootet pixel experience 10 with unlocked bootloader.
I dont know what to do now. Can someone help me? And apologies for my bad english.
Best regards

So i downloaded the MiFlash tool and tried to flash stock firmware but i got an error message. Does someone know what it means?

I think you should try to enter the phone in EDL (maybe with the test point method) and then try to flash the stock firmware as you did.
Does the phone notification LED turns on when you plug in the deviceto the PC?

your phone entered edl mode ... probably due to update ota...do you have a jasmine to wayne conversion ...did you flash firmware package ?
anyway you cam flash a rom but probably the error in miflash is bevause you have ARB ..look for ARB4 rom and flash that to boot
if you didn't convert or have ARB4 or didn't update ota or something like that you probably have some broken hardware in phone and must replace some pieces and miflash gives errors because it cant fix hardware

Doogee s68pro not booting up after magisk update, black screen. What can i do to fix this?

So, I recently updated magisk on my phone and as usual to update my phone restarts, but this time it didn't boot up.
I think its in bootloop because when i connect it to my pc with a usb cable it goes on and off also, i cannot access to TWRP.

Can you get to bootloader (fastboot)?
If so you can restore a stock boot image and start over, or try to boot to TWRP with fastboot boot twrp.img and restore the boot image from there and then flash the installer (rename the .apk to .zip as per the new v22+ installation instructions).

I am unable to go into the bootloader or maybe im just doing it the wrong way do you mind guiding me? :/

or maybe i don't have the drivers..

my phone just connects and disconnects, so im not so sure i can go into the bootloader and launch a comand.

Can you shutdown your phone?

i don't think, because it's always turning on and off because the usb sound is going off and on in my pc so i dont really know

You need to use a button combo to get to bootloader or recovery (since you can't boot to Android). A quick web search gives this:

Exactly like what happen to my device as well

Nope, it does not let me go into the bootloader. Not even with the button combo.

Do you have twrp installed on your phone by any chance? Also a stock boot.img?

First you need to calm down I know how frustrating seeing your device on bootloop and can't even shutdown it ...

i do not have twrp, but i can download a stock boot.img

would you like me to guide you how to fix it i don't have anything to do?

Yes, thank you.

Your device is going on bootloop right now and keep vibrating right?

it's not vibrating. but it probably is in bootloop

lol mine is vibrating while on bootloop okay enough chitchat let's start
vibration is actually good indication for the next process
prepare ADB and USB cable
Now press Power Button and VOL UP at the same time wait for vibration let go Power Button keep holding VOL up for at least 3secs then let go

it's still not vibrating

now press VOL DOWN there's 3 out of 1 chance that you actually made it to fastboot mode ...
