bricked my lg o4x.... please Help... - LG Optimus 4X HD

Hello,
i was trying to unlock my bootloader...i tried everything... my lg is euro-xxx
after a hundred attempts there was an error message every time i tried to boot from the bootloader ; [security error] boot image signature..
i tried to fix it flashing the original bootloader from the ''all in one tool''.. nothing happened.. and because i am a stupid noob i thought that a factory reset might re-wright this and restore it to its previous state... and guess what.. it didn't! and now my phone is dead. Even when i connect it via usb (it doesn't matter if it is the wall charger or the pc) the phone keeps looping to that error message....
please help me, i am desperate....:crying:

just after the first post there was a very fortunate turn of events!!!...at least that's what i think... when i connected my phone to the pc the loop in the bootloader stopped and there is a charging indicator instead.. is there anyone who can tell me if there is a way to fix my poor lg? i only have it for a week.......

if it is triing to update it can loop, try to remove the battery

What did you do to unlock your bootloader?

Did you root your phone first?
The same problem happened to me when i tried unlocking the bootloader however i just kept on restarting my device and it worked for me; try to turn on the phone by only using the charger. Also keep tapping the power button while the phone is turning on (try everything, i dont know if it will work for you but it just worked for me).
If you manged to turn on your phone use the LG PC Suite to do an Emergency recovery, this will reset your phone. Then i unlocked the boot loader first before rooting the phone use cmd instead of the all in one program.
there are yt videos on how to do this but i am a new user iam not able to post them

help
someone please help me, i was actualizano my lg 4x through lg mobile support tool gave me an error and now enceindo not in any way if sw or anything only when I connect it to my pc recognizes it as apx device. please help.racke

[Q] HELP: Stuck in bootloader or no USB

Hi All,
from one moment to another my X1 decided to boot into bootloader mode.
The strange thing is however, that when I connect it to the USB of my PC and reset the X1, it boots normally. Well, almost normal as the USB doesn't seem to be working.
I flashed the rom to APP-SW_X1_GENERIC_UK_1213-6450_R3AA010__KOVS using the SDCard and that worked without a problem. But still the X1 boots into bootloader mode (except when connected to the PC).
I tried a hardreset, pressed the volume down button several times (to make sure it isn't stuck), tried to use MTTY (but that doesn't show a prompt), but nothing seems to help.
Is there anyone who can help me with this, because I'm out of ideas....
Update:
I managed to boot the OS (USB connected) and install HSPL using Xperia-SSPL-Manual. This succeeded and I now have SPL-0.78.OliNext. I flashed the phone to a new ROM (826x_KOVSKY_29017_2021), and that succeeded as well. It didn't solve my problem however. I still get the bootloader screen when I start the phone and can only start the OS by starting with USB connected...
Update2:
Yesterday evening I took the whole phone apart to make sure no buttons are/were stuck. Didn't find anything, put it back together and it still boots into bootloader.
I also managed to get a connection to the phone using NueTTY. I executed command Set 14 0, restarted the phone...and still it boots into bootloader.
If there is any one who knows of something that I haven't tried yet, PLEASE let me know....
same problem,,if there's a way to flash recovery from sd card in fastboot mode,,that'd be great

Flashing the ROM is no problem, I can put every ROM on it that I like. But even after flashing the ROM the phone still starts in bootloader....
You can try to go into the bootloader on ur pc and use recovery.bat with fastboot.

hi, I'm kind of having the same issue as you do..can you please be of help and tell me how did you manage to HSPL it to 0.78.OliNex?
Correct me If I am wrong, but you must copy Xpera_SSPL_Manual. exe on X1, run it from file explorer and then run X1_HardSPL.exe on your PC, whlie X1 is connected via usb (although mine also doesn't recognize the X1) ?
i would really apreciate it... thnx
i have the same problem guys, did anyone of you found any solution for this?

Have you tried to do a task29 with KovskyAdvancedRUU?

[Q] How to unbrick my 4X - a question of life and death!

I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB.
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
I think it’s still locked.
This method hasn’t help either…
http://forum.xda-developers.com/showthread.php?t=2251407
What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.
Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA and elsewhere - without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM.
If none of those things that you said doesnt work, as last resort you should try this

Thank you for a quick reply! However the autor of the method says:
i mean when you get stucked with S/W screen, and you can't flash the device in any way
Click to expand...
Click to collapse
In my case I can't say that I'm stuck with S/W screen. Because I don't even get in there. Any PC in my home (XP/Windows 7) don't even recognize that a mobile has been connected to it. So there is no S/W screen. The only way I can get in S/W screen is to keep the battery in, but it doesn't solve anything. Because the phone remains unrecognized to PC. Therefore I'm unable to flash anything. A simple explanation in here arose: the USB port in my phone is faulty. BUT, how that can be, when the USB charging works fine and even S/W screen appears while the battery is in?
Either way I'll keep your suggestion as the final solution(since I'm very skeptical of it and also dont have screwdriver small enought to take out those tine srews) if there will be no other responce to my problem.
I'm not very experienced in things like this, but when I was flashing kdz to my phone, my computer wasn't able to recognize the phone with battery out, so I did whole process with battery in (and it worked)
anyway if you want to unlock the bootloader you have to update to official JB (just flash JB kdz and then wipe data in LG recovery to prevent bootloop)
so first you have to connect somehow your phone in sw mode to computer
then flash JB kdz and wipe data in LG recovery (it should be back even if you've flashed twrp)
and finally root JB and unlock bootloader (for example this way I found by two clicks here at xda, just browse Optimus 4x general category: http://forum.xda-developers.com/showthread.php?t=2251407 )
I hope I helped you a bit
I agree with you SuperLamic. Especially with this:
so first you have to connect somehow your phone in sw mode to computer
Click to expand...
Click to collapse
My only hope is to flash kdz file using fastboot mode. However after days of searching on XDA, installing all kinds of drivers, trying different methods etc., I'm still unable to connect my phone to PC.
Any PC I tryied so far haven't even made a sound while pluging my LG to it. Nor it's vissible in the list of connected USB devices.
So now I'm sure that a USB port on my phone is faulty There is no other possible explanation. But thank you all for your suggestions anyway.
P.S.
There is maybe a tiny chance for workaround by unlocking the bootloader without PC. But this method doesn't work. http://forum.xda-developers.com/showthread.php?t=2251407 With unlocked bootloader I woud be able to solve the problem without PC. Right now I can't install TWRP nor CWM because they require bootloader to be unlocked. CWM in ROM Manager always says that installation was successful but actualy, it wasn't. Since there is always this error when I try to load recowery mod...
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
EDIT:
So I find out that only JB ROMs can be unlocked. It's not possible with my stock ICS. So there is really only one solution: repair my USB port on LG to flash kdz. But I'm afraid that these days a repair will cost more than the phone itself :[

So in the last days I bricked my z2 pro by closing the bootloader with a custom installed, and to solve the problem I put it in EDL mode and I used the flash mi, but now when I press the power button it just vibrates and flashes a green Led, but it does not turn on, I already tried several combinations of buttons to get into fastboot and nothing, and when I plugged the usb into the pc it shows nothing

Hard-Bricked Huawei Mate S - any way to fix it?

So my problem is that i wanted to root my Huawei Mate S, so I had to unlock the Bootloader.
It said that it was successful and unlocked, so I continued rooting, which seemed fine.
But then I got stuck in a bootload and I havent been able to access my phone ever since.
At first I was able to charge it, because the red LED was flashing, but nothing else happened.
Now I can´t do anything; If it´s connected to Power all it does is vibrating one short time, if I try to access Download- or Recovery-Mode, which means that its not detected by the PC...
Is there any way to fix it?
Thanks in advance.

But how am I suppossed to do so, if I can't access my phone at all ( no recovery-/ download-mode)and my computer won't recognize it being connected?
have you tried to charge the phone only via the pc usb port or did you use a wall charger? it wouldn't hurt to connect it to a wall charger and let it rest a few hours if you haven't done that yet. then try to connect it to the pc and to try turning it on either in recovery or fastboot mode.

I actually did use a wall charger, but I'm still not able to do anything...
I just don't understand why it is vibrating when I try to boot into recovery mode...
To me that means that the phone is not completely dead...
So no one actually hast an idea?

Sony Xperia E1 (D2005) Failed Philz Recovery. Stuck in bootloop with no recovery!!!

Hello everyone. I am in real trouble here and I will explain why. I have recently tried to get the custom recovery with a locked bootloader (philz touch) on my device by following a thread. As far as I know I followed the guide properly but when my device rebooted it bootlooped 10x and then when my device booted it froze at the lock screen and restarted. now my device bootloops several times before boot and once it boots I get 1min at the most before it freezes and restarts. Also sometimes it fails to boot at all and it gets stuck in an infinate bootloop and I have to pull the battery. when I connect it to my laptop with a usb cable it is only recognised if the device boots but I only have a few seconds because the phone reboots and disconnects when I try and enter recovery or download mode my screen goes black and the only way to get of this is to pull the battery. I have also tried to connect to my laptop when on this black screen but i have had no success. If I turn the phone off and connect it to my laptop via usb when I am on the "battery charging screen" it appears on my computer as a unknown usb device. i do have all the drivers ect. my device is rooted with baidu root if that helps. ive heard of a little device called a usb jig would that be useful to me? sorry if this is not worded very well or looks like a book. Im not a idiot but not quite "tech savy" i would like to think i am somewhere in the middle. I have been using this site for years for various devices and always managed to succeed. help would be apprecited. Thanks
UPDATE: I have tried to factory reset from the settings but for some reason the button is greyed out and it wont let me press it! also I cannot connect to wifi or mobile data these are greyed out aswell and when I try to connect via the sliders in the settings menu they are also greyed out!!!

Hi, you need an unlocked bootloader for it to work properly. You can find how to unlock the bootloader by going to Sony's website and see where it says to unlock the bootloader or just look for it on Google. To get back to the stock rom (Android 4.4.2 KitKat), you will need Flashtool and the stock rom. You can find the rom on Google by just typing "sony xperia e1 d2005 stock rom". To get the recovery just try looking for it on XDA. And USB Jig will not work for Sony devices. USB Jig is only designed to work with Samsung devices.
