I'm stuck in a bootloop... after flashing latest 23.4.A.0.546it with flashable.zip on my xperia z3 compact the phone will turn on and the "optimizing apps" message will prompt, when the process finishes I receive error "android.process.media stopped working". My phone is rooted with locked bootloader.
I have a cwm backup but I can't access dual recovery, red led appear when pressing volume up on boot.
So I opened flashtool, installed drivers and connected the phone with volume down pressed but it gives me error "For flashtool, Unknown Sources and Debugging must be checked in phone settings" when I try to flash the ftf. If i retry I get error " Error in processHeader : 6 : The handle is invalid. ".
Now I can't flash with flashtool, I can't restore my backup or access the phone. Any help would be appreciated.
Try flashing with the phone off. I can't remember what button combo shut off my phone when it was looping. It was like Power button and Volume down or Power button and Volume up. Once the phone is off, try flashing the FW. Once the phone thing pop up shows up, hold volume down and connect the USB to the PC.

That's what I'm doing. Power button + volume up button turns the phone off and then I press power button + volume down so I can connect the phone in flash mode, when I try to flash I get error "For flashtool, Unknown Sources and Debugging must be checked in phone settings".
apparently usb debugging was not enabled when I flashed via flashable.zip and now I'm stuck in a bootloop. Is there anyway to fix this problem?
Similar problem, no solution
Ok what I did is recovering with companion and then re-root, apply update and finally flash with debugging mode on. Kinda long process but I had backup so everything is working just fine and I didn't lose anything.

Hi all
As the title states my phone appears to be stuck in a boot loop of sorts.
So I loaded the German V20N via KDZ updater last week and that worked perfectly.
I decided I wanted to use Zeus v2.1 by Huexxx, but I needed a rooted device for this.
So I put the phone into update mode by pressing vol+ and power button.
I then used KDZ updater once again using V10B. This also appeared to update fine.
However when the phone finally booted up I got many many errors of:
"process system root is not responding".
I tried to force close them but to no avail, so I removed the battery.
I powered the phone on yet again and then it shows the LG logo then reboots possibly a few times.
After that it eventually lands up showing the Unlock screen but the touch keys at the bottom are flashing. It will then reboot again and do the same thing.
I tried removing the battery pressing vol+ and power and then plugging it into the USB to get the software update mode. However the phone just turns on instead of showing the update screen.
I have also tried pressing vol- and power. It also just appears to turn the phone on.
Other errors received are:
"The process android.process.acore has stopped unexpectedly. Please try again"
The errors pop up and and eventually the phone will hang and restart before I can actually do anything on it.
The computer doesn't seem to pick up anything when it's plugged into the USB either
http://forum.xda-developers.com/showthread.php?t=1448803
I did see that thread, but I was under the impression that because I could not get to the software update mode that it wouldn't work.
As it turns out... You must not press vol+ and power when plugging into usb. Just the vol+ key.
Will let you know if it works via SmartFlashTool.
Thanks
Feel rather silly now...
It seems to be working!
Hopefully I will not screw it up again.
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!
I tried Philz recovery to install a new rom but after choosing "clean to install new rom", I rebooted the phone by mistake :crying::crying::crying::crying::crying: And now I can't turn it on with the power button, when I try to force reset by holding both power button and volume up, it just buzz once and Sony screen show up then down just after a few seconds. After that nothing happens. I tried to connect it to PC and I just got the notification that USB cannot recognised... I can't enter fastboot or flashboot mode
How can I do now?!?!? I'm so feaking out now :crying::crying:
Have you tried flashtool?
If you use it to flash a stock rom, your phone may work again.

Try to get to recovery again?
So I tried installing Magisk, but it failed. I then flashed the Magisk uninstall zip file and rebooted, but now my phone won't turn on. When I hold the power button it vibrates once. Nothing happens when I hold power + vol up/down.
I tried flashing with FlashTool but it says it can't detect the driver. Also I don't think USB debugging is enabled, how can I enable it if the phone is bricked? Thanks in advance.
UPDATE: this is fixed now, drivers didn't install properly in windows 10
I don't know what happened, today I woke up, pick my phone, anwser a few messages and them suddenly my phone reboot and all goes blank. So I connected it to the power, the cellphone started to blink the blank led light e shows the power symbol over and over, them after a time shows this message: "Start Up Failed" Your device didn't start successfully. Use the Software Repair Assistant on computer to repair your device."
I did what was told, but after all the recover procedure complete the same messages and bliking behaviors starts again. My phone is not rooted. Is there a solution that I can try to solve this issue?
Thanks in Advance.
Motorola G5S Plus reboot
Try this. Start the bootloader (Boats Vol -, + power at the same time), browse with Vol + or Vol-, search for "recovery mode", with power you accept. If "no command" appears on the screen, press power + Vol +. There you have many options. You can do Factory reset.

Hi lokochris, thanks for answering
When I select the recovery mode, this message appears in the phone: "failed to validate recovery mode. ERROR: Failed to pass validation, backup to fastboot."
The factory reset only reboot again, and again blank light blinking and power logo in a loop.
Motorola G5S Plus reboot
use this method https://www.youtube.com/watch?v=fMWbC_c6758
This youtube method was the first thing I tried. It shows the Motorola logo and returns to the same message. I believe something is blocked, because the Power logo remains in Loop and the white light is flashing.
These results are displayed only when the phone is charging. Without charging or cable on the PC, my phone doesn't even start.
Motorola G5S Plus reboot
Try this. If the problem continues, it may be a hardware problem. I have read over there, if you try to remove google account or unlock bootloader, the phone enters hard brick and it is almost unbrick.

Hi lokochris,
What I need to do to run this batch scripts? because the link only talks about the scripts, but not what you need to do to run them.
Moto g5s plus reboot
Just run the one you need ( bootload), connect the phone to the PC and run automatically
