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!

Hello,
After rooting my p880, my phone hangs at boot. Just after the boot sound (*pling* ) the phone is hanging. The boot image is still moving.
Things I tried already:
I followed this thread http://forum.xda-developers.com/showthread.php?t=2069723, which tells to do a kdz update. This is not working, as I am not able to get to the S/W upgrade screen. Instead, when I start the phone using the power button + volume down, i get the Android system recovery menu (3e).
I tried to upload a new (cyanogenmod) rom using adb sideload, but that didn't work, as the file I used was damaged (I will retry with new file).
I also did a factory reset and a cache wipe.
Can someone tell me what is best to do?
Kind regards

My device went int bootloop suddenly while I was using it. I not able to get in fastboot (when I press Power + Down it shows fastboot window for a sec and reboots again ) or recovery mode(When I press Power + Up, Screen shows up saying no command).
I was using official build(July patch). I have not enabled ADB. My bootloader is also locked.
Is it possible to get this device working?
Any help will be appreciated.

This is normal behavior of stock recovery: seeing "no command" hold "power" and click "Vol+", - to get to the stock recovery menu (btw, search would 100% give you this tip even in these forums).
As you are locked, and thus you have surely lost user data, you can try to make factory reset from recovery menu.
Yet I'd try to connect phone to power and make numerous attempts to reboot, occasionally rebooting into fastboot and into recovery, - with the hope that phone will switch into the other A/B slot.
If nothing helps, TestPoint/EDL is the only option except service.
But again, the problem may be hardware issue, and as you are supposed to disassemble phone preforming TestPoint, I'd check connectors inside and tried to reboot again before reflashing in MiFlash. And do not forget to reflash in fastboot after MiFlash reflash (and unlock phone - which I did immediately after purchase).
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 ...
This message I get when I try to power up my Note 9 N960F/DS.
I got it this way: Been running the same ROM for 2 years. Time to upgrade. Upgraded TWRP via the app. After downloading the ROM image to SD card, I tapped an app called Reboot, with the Recovery option. I suspect this app is from some old installation, and ended up on this unit via data restore. Now all I get is this message on a black screen. No logo, nothing. Message flashes once. If I plug into PC, message flashes repeatedly. Cannot boot to recovery using Vol-+Pwr, Vol++Pwr ineffective.
I suspect I bricked the phone, but I seem to remember once breaking out of this 2 years back, I think. Any ideas, clues, anything?
Try this, power off phone. Press volume up and bixby button and while pressing buttons insert data cable, phone should go to downlaod mode. OPen odin and flash stock firmware.
OK, tried it, display showed the same message until I released the buttons, then flashed the message every 4 seconds until disconnected.
OK, got it into download mode, reflashed twrp, now it's in a boot loop. Will continue working this.
It took a few tries, but I not only got everything working, I restored my data backup and upgraded to Android 10. Thanks all!

HOW DID YOU DO THIS, I HAVE THE EXACT SAME ISSUE AND AFTER HOURS OF SEARCHING YOU'RE THE ONLY OTHER PERSON WHO'S HAD THIS ISSSUE. PLEASE HELP, I CANNOT GET INTO DOWNLOAD MODE NO MATTER WHAT I DO
Holding Power & Volume Down beginning screen says Bootloader Unlocked Cannot Be trusted and then goes to Android Recovery. Tried to Factory Data reset several times, but keeps coming back to Bootloader Unlocked. I can not even tell if I am over charging or if it is charged at all. Can I get Samsung files from Samsung site to download? Which ones do you think would be best course. I just want it to be factory data reset. HELP! My recovery screen pics are attached.

Why are you holding vol down? Holding vol down and power is the method used to boot to recovery. And once the bootloader is unlocked you will always get the nag screen saying it is unsafe. Ignore it. What happens if you just push the power button WITHOUT pushing vol down?

I know that is what you said. I'm still asking why? You are complaining that that takes you to Android recovery but that is what that key combination is supposed to do.

Oh Sorry, That is the only thing I can get to come up on tablet after Samsung Logo and Bootloader Unlocked. Then just blank screen. So I have trying to find ways to load OS/Firmware back on system since the factory data reset didn't work.

Then you need to boot to download mode, not recovery. Plug the USB cable into a PC and not the tablet. Turn the tablet off. Then, while holding both vol down and vol up, plug the cable into the tablet. You can download the latest firmware using frija.exe. Flash the firmware using Odin on the PC.

I was able to successfully download the firmware and flashed it with odin. The only problem now is odin indicates PASS! in green on PC and seems to be finished, but the odin screen on PC has not closed. The tablet downloading screen remains open with the progress bar all the way at the end. Should I hit exit or reset on odin on PC or alternatively select AutoStart in options?

I don't know. The Odin screen remaining open is normal. But, unless you unchecked the auto-reboot in Odin options, the tablet should have rebooted when it finished flashing. If it doesn't, I guess the only thing you can do is manually reboot the tablet by holding vol down and power for about 7 seconds.

I did uncheck the auto-reboot which the directions I had said to do so. So I just let it sit there for about 6-7 hours plugged into PC. I figured then there was no way it wasn't done installing so i unplugged from PC. After like 5 minutes or so the tablet came on with the beginning screen for setting up tablet. Now I just have to figure how much crap I really need on it. I wish I could get rid of Samsung Flow so I could use the tablet for Fan Duel. Thanks for your help. Have a good weekend.
