L7 P700 bricked with first version of custom kernel... please help.

I have an p700 with cm10( last version ), cmw touch last version, crossbreeder and first version of custom kernel (without oc). Run perfectly until yesterday. I intended to flash new kernel (V4). Battery was at 9 percent full. Reboot in recovery mode and... shock ... black screen. My phone is dead. Nothing... no power, no joy....
Thank you for help...

did your charge it? did it boot? can you enter recovery or emergency?
and why did you flash with only 9%?!?

From my experience with p500 (optimus one) 9% battery it more then enough for flash an kernel ... but it seems that 9% was not for real (first version of custom kernel has problem with battery status). Anyway ... after I downloaded the new kernel (v4), from reboot menu (cm10) I gave the reboot recovery command ... "Rebooting now" ... and ... instead of recovery mode, the phone was powered off. So I never got to flash ... Now it's dead, does nothing ... No power (with or without battery and the power cord plugged in), no recovery mode, no emergency mode, no charging.
I used original charger (0,75 A), after that an Samsung charger (1 A), after that an Logitech charger (1.5A).
I tryed to charge with my laptop from USB 2.0 port and 3.0 port, and with my desktop computer ( USB 2.0, 3.0 )... All I've got is THE BIG NOTHING.
Thank you for replay...

Recently it works fine and I did nothing..
Battry on 66%, and try to refresh the system via reboot.
Few seconds, screenlight turn off.
I've keep waiting. it usualy showing LG logo after 10seconds.
But nothing happen.
Try to power on and also try CMW shortcut.

Unfortunately, the only way to bring it to life is JTAG. I paid ~ 35Euro for JTAG-ing.
damn
damn i want cm10 too, bet im to scared with bootloader unlocking etc after reading posts...
Its happend to me too and i found a way to get out there
Tip: NEXT TIME DO NOT INSTALL ANY KERNEL!!!
This is the solution:
1. Download LG Optimus L7 USB Driver for Windows | Mac
Download official LG Optimus L7 stock firmware from this page. The file would be a .kdz file. Download the appropriate firmware according to your network provider and country.
3. Download KDZ updater and install it on your computer.
4.The zip file has a Microsoft XML parser, make sure you run it as an administrator and restart your PC. This will solve the wparam 100 and lparam 6 issue mentioned in a comment below.
5.The next step is to put your phone into emergency mode. To do this, remove the battery of your phone and re-insert it (don’t turn it on). Press and hold Volume Up button and Volume Down button. While you are pressing the two buttons, press the Power button. So now, you must be pressing all three buttons together. See this video
6.Your phone will boot into emergency mode and you should see a yellow screen with Emergency mode written on it.
7.Pick up the USB Cable and connect your phone to the computer via the USB Cable.
8.Run KDZ updater as Administrator.
9.Choose the following options in KDZ Updater: Type: 3GQCT Phone Mode: DIAG and KDZ file is the one you downloaded in step 3.
*image:
http://www.hackmyandroid.com/wp-content/uploads/2012/09/Root-LG-P350-LG-Update.png
10.Re-check with the image above and ensure that you have the appropriate settings on the KDZ updater.
11.Take a deep breath and click on “Launch Software Update” button.
12.This process is usually long. It take quite a long time for the firmware to be flashed on your phone.
13.If everything goes well, you will see “Finished” written in the log screen and your phone will change to switched off mode from Emergency mode.
14.The next time you turn it on, your phone will take a lot of time to reboot. Stay Cool! its normal.

It is not possible to run that file as an administrator. I tried on 3 different systems: Win 8x64, Win 7x64 and Win 7x32. I have a logo stucked but after few seconds it plays the sound and logo does it's animation then same static logo and then it stucks. Is there any solution besides j-taging? Does warranty service cover this as a defect and repair for free?
Thanks

Try hard reset :
1. When the phone is switched off, press and hold the Volume down key + Power key with your left hand.
2. When the LED on the bottom of the phone lights up, touch and hold the Menu key with your right hand. You need to do this immediately, before the screen displays the LG logo. Make sure your left hand is still holding the Volume down and Power keys.
Then release the power key at vibration time.
3. When the LG logo is displayed on the screen, continue to hold the keys for around 2 seconds, and then release all
them at the same time, before the LG logo disappears.
Leave your phone for at least a minute while the hard reset is carried out. You will then be able to switch your phone back on.
Caution: If you perform a hard reset, all user applications and user data will be deleted. This cannot be reversed.

LG G2 D802 hanging in bootloop

Hello everybody,
I am an owner of an
rooted LG G2 D802. When i got the devide i used an Stock Rom from storagecow.eu (the Germany Open 16GB Kitkat D80220D_00.kzd). After that i rooted the phone and everything worked perfect for a couple of months.
But a week before the phone began to lagg extremely, so i decided to restart the phone. But after that I got stuck in a bootloop, without knowing what reason caused the trouble.
This is how it looks like when i get the bootloop.:
LG logo appears, LG Animation starts, blinking LG logo comes back and thats all. And the LED is blinking continuously in the colors green-lightblue.

I tried the following things:
Hard Reset
Only getting into the menue with the combination:
Power und Vol - untill the LG logo appears.
Power und Vol - releasing, then pressing Vol+ and Vol- untill Recovery appears.
Click to expand...
Click to collapse
I navigate through the menue and then do a hard reset. After all is done the phone stucks at the bootloop again (LG Logo constantly showing up) and the LED is blinking in the colors green-blue.

Recovery Mode
Instruction:
Now, press the volume down and power button at the same time for 2 or 3 seconds until the LG logo appears on the display.
Then release the buttons and then press and hold them again.

Then the LG logo appears and stays for a few seconds. After that it only shows the battery charging symbol. But there are some Windows sounds that pop up when you successfully connect some USB devices. But nonetheless it does not help me to fix my phone.

Hello!
If the LG Logo and then it only starts to charge the phone, then you're not entering download mode the right way.
Please follow this guide:
http://forum.xda-developers.com/showthread.php?t=2432476
To enter download mode: Press and hold the power button for 12 seconds to turn off the phone.¨
Press and hold Volume Up and plug the phone into your computer.
NOTE: make sure you have the right drivers installed. Everything you need is listed within that guide!
Hi, thanks for info.
Today i tried everything again. This time i took a laptop with fresh installed Win7 64Bit, no Antivirus installed, all updates included and Visual C++ installed as shown in the thread. After that i downloaded the Stock Rom Germany Open 16GB KitKat D80220D_00.kdz, then i installed the drivers and reboot my laptop. Then i extract the Flash Tool.
Every piece of software i downloaded from the links listed in the thread.
And still i can not enter the download mode. First of all i ensure that the phone is off by holding the power button for 12 seconds after i try to start the phone. Then everything gets turned off.
I did this:
1) I installed visual C++, installed LG drivers, rebooted pc, extracted LG flash tool
2) Turn off the phone (12 seconds holding power button)
3) Plug in USB micro to Smartphone and keep pressing all time long the Vol+ key till the end of the process
4) Plug in USB to laptop and connect Smartphone with Laptop
5) Windows shows that drivers are being installed (it recognizes some USB connected to pc). After a while it shows the message that everything was installed correctly.
6) Simultanously the LG Logo appears on the phone and after a few seconds it only shows me that the phone ist being charged (100%-battery-status-symbol).
7) But on the phone there does not pop up the message "Download mode". And in Windows i cant see the smartphone mounted with a drive letter or anything similar to it. When i start the LG Flashtool and try to flash it, then it shows me during the recognition of the phone "the phone is disconnected from pc", so the Flashtool is not able to flash (because the phone does not seem to enter download mode).
Please help me to get my LG D802 back
I dont know what to do now.
Any suggestions?
Furthermore I ask myself if I just could buy a 32GB LG G2 with a broken display on ebay and replace the display of my 16GB D802 with the components of the new bought 32GB D802 (without boot loop)?
This I could do in the worst case if nothing else helps
Question B:
I have a LG G2 (D802) with 16GB with a Bootloop.
If I buy a LG G2 (D802) with 32GB with a broken display, can I replace the working display and all of its components with the broken Display from the D802 (32GB) so that i get a working 32GB-version of the phone?
So i want to start a repair to get my G2 back as soon as possible.
Can anyone please answer?
Question A:
Shall i record a video of me trying to enter the Download Mode of my G2?
What to do now
Is there nobody who has any suggestions on this problem?
Is the phone really that much messed up?
Edit: Nobody answered my questions, so i decided to call the LG support and to send the phone to their repair services. So the phone is sent to their repair services now. Lets see what happens.
Hi, the device has been repaired by the LG Electronics Support (technician Support)
"Failure: Swap Board (Main, RF): Impossible to Repair"
Replacement: PCB Assembly, Main, Refurbished Board + 1x Battery"
Thx for the support!
Hello, I'm having some of the same issues that you were having with your G2 and I'm debating on sending it back for repair.
However I was wondering how much it cost you for the repair or if the phone was under warranty? My phone is about 2 months out of warranty so I'm worried it will cost me more to fix it then to just buy a new phone.
Thanks for your help!

[Q] Problem with download mode (N900)

Hello guys.
So I just flashed the russian Lollipop firmware that came out for the N900 into my device. I followed all the procedure to the letter (I am really cautious and it's not the first time I've flashed stuff); went to download mode, connected my Note to the cable, added the MD5 to Odin and started flashing. The procedure finished and the phone restarted, but I got a black screen after the "Samsung Galaxy Note 3" screen you get when you start the phone, but that wasn't really the problem since I read that a lot of people got that black screen and solved it by flashing the firmware again. My problem is when I go to download mode (power off the phone then volume down + power + home) I get the "Warning!!" confirmation screen, and then I press Volume up to continue, nothing happens!! Even when I press Volume down (which should get out of download mode and restart the device) nothing happens!
In case you're wondering, I can get with no problem into recovery mode.
Is there a way I can fix this and get into download mode? Maybe a way to get directly into download mode without the confirmation screen (I did read somewhere that holding volume up + volume down while turned off and then connecting the cable to the phone should get it directly into download mode, but that apparently doesn't work for me)
Help would be much appreciated, and sorry for the bad english.

LG Optimus L5 610 / 612 (f) - UNBRICK - Emergency Mode Problem

Hello! Same problem...
My L5 is making me crazy... It has CyanogenMod 10 nighlty. A friend of mine was using it and he tried to install the GAPPS after he did a factory reset. I have no idea what guide he used but it got soft bricked... It's constantly showing a "stopped working" message and after a while reboots by itself.
I tried to do a factory reset but it always returns to the same point, same apps installed, everything like the reset never happened. I even used CWM to reset it and it allways goes back to the same recovery point.
After a while I decided to flash a stock room but here's the problem: I can't get into emergency mode.
After reading ALL post about it I found that there's at least three ways of entering EM, (1) down VOL and plug in usb cable without battery; (2) down+up VOL and plug in usb; (3) down+up VOL + power botton.
Conclusions:
(1) - gives me a screen full of code like a command line
(2) - White screen
(3) - White screen
I've read ALL the unbrinking post on the internet, including xda, and none of them helped.
The KDZ Updater never recognizes the phone. I installed all the drivers but everytime I plug in the phone it installes the same LGE MTP drive...
Can anyone help, please?!
How to enter Emergency mode? How to flash another rom?

Unplug usb from computer.
Try to power off ( holding power button for some time. Don't leave power button again if lg logo appears.)
Phone Will be off now.
Now hold volume up button and plug the usb.
You should get download mode.
**your usb port may be loose.
Don't shake usb cable while flashing using lg flash tool.
