I installed stock ROM after having CM11 for some time, when I installed updates for stock, booting stopped at CWM recovery. I used method at http://petesblog.net/blog/how-to-fix-clockworkmod-recovery-boot-loop-issue, 'echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0', and now my phone can't be powered on. Is there a way to fix it?
Please move to other forum, I overlooked it..
Have you ever tried to put your phone into emergency/download mode? Please try to do this and if the phone gets into emergency mode i think that it is possibe to fix it.
To enter in download mode:
1. Remove battery
2. Put usb to computer and phone (w/o battery)
3. Hold "Vol up" button
4. Put battery back
You will get into download mode (aka emergency mode).
I forgot to say that it is impossible to enter emergency mode. Windows detects the device in the Device manager, but I can do nothing with it. I installed some qualcomm drivers so it's detected as a serial port, but I can't send data ot the phone.
I don't know, what are the partition table for L9 II.
Try to unpack KDZ to IMGs, run Ubuntu (or other linux-based system) and dd if boot.img or aboot.img like in the "LG G2 No emergency mode, no download mode"
Sent from my E430 (L3 II Single)
Not possible because linux does not detect the phone's filesystem (ls /dev/sd*). Also windows detects it as qhsusb_dload.

Hi everyone
I recently got my first android phone - Samsung Galaxy W.
I decided to install a custom rom. Before that i had to root my phone which i did without any problems. After that i had to flash ClockworkMod v5.5.0.4. I downloaded the file which was in zip however i didn't extract it (which is what i should have done) and copied into my phone's memory. After that i put this code in the command promt
adb shell
$su
#dd if=/sdcard/
recovery-clockwork-5.5.0.4-ancora.zip of=/dev/block/mmcblk0p13
After rebooting the phone i can only get into the download mode in which nothing happens. And when i connent the phone to my pc the computer doesn't detect that my phone is connected. What shall i do now? Is my phone a brick now?
Okay i found out that my pc detects my phone however it is marked as unspecified device which means that i can't do anything with it.
Tommorow i install ubuntu and see if i will be able to connect to it.
Any other suggestions?
After attepmting to root, I ended up with a "Security Error" problem. I ended up using fastboot to flash the uboot and xloader. And now since then the phone won't do anything at all. I can enter fastboot, it will even show on the screen when it enters fastboot. But I can no longer enter S/W mode, and the phone won't turn on Using the power buttons or any combinations of buttons. It just shows a blank screen if I try turning it on by holding power. I can't adb into it, and the LG Support Tool can't find the phone. How can I get S/W back at least so I can flash it or something?
It's a p769 and was previously running JB
Which x & u did you flash?
I prefer to do things manually, another thing, who's fastboot did you use? If you used Lelus select option #1 and copy the files p1ics769.bin & p2ics769.bin (found in the "xu" folder) into the "yours" folder.
When you have the inverted fastboot on your phone, type the following
fastboot devices (to check if your are connected)
fastboot flash x-loader p1ics769.bin
fastboot flash u-boot p2ics769.bin
After you do this, take out your battery and hold vol up and enter the usb cable into the pc & phone & put the battery back. If that doesn't work, enter battery, hold vol up and enter usb cable, keep trying different usb ports on your pc.
Fixed!
Flashing the u-boot and x-loader worked perfectly. Put me back at where I was originally which was the "Security Error". Then I just went back into S/W mode, and used the KDZ flash and everything works now! Thank you so much.
Just for those who have trouble, if you have the p769 with JB, and you run into "Security Error" flash the x-loader and u-boot to match ICS, then the LG tool will find your phone. Then you can just flash the JB KDZ
Did u flashed KDZ offline

HI there I am trying to flash KDZ using offline KDZ method.
I can enter into S/W mode
But it LG software does not detects phone.
It was happening me to previously too. but if we turn on USB debugging when phone was On. It was working.
But the thing is now that I am stuck into boot loop.
And in S/W mode LG tool doesnot detect phone (but I can my phone connected in Device manager)
So LG tool stops at 14%.
HELP ME OUT PLEASE.
Hi,
My phone is actually unusable (no boot (it keeps rebooting), no recovery (when i try vol down + home + power it keeps rebooting), i tried using fastboot following this http://forum.xda-developers.com/showthread.php?t=2119090
But it doesn't work. I can only access s/w upgrade screen but i can't recover phone using LG mobile support tool but it stops at 50%.
My question is : how can I install ADB for my phone (p760) ? (I remember i was able to enable fastboot with adb last month)
Thank you

If he really erased LAF from his phone he can not get into download mode any more, because LAF is the download mode.
If he was in the situation where he could erase LAF he could have easily rescued his phone by flashing stock images.
Now it will be hard to rescue but there is nothing to loose any more.
You can try to get into fastboot by:
hold vol + button and connect usb cable.
As soon as you see the fastboot screen release all buttons.
Try to connect your phone via fastboot.
Try to flash original aboot + original LAF
Maybe flash original boot + system
or
Go to Download mode and flash original KDZ in emergency mode (CSE).

Thank u zaaap! Unfortunately even when i release all buttons the telephone get into the download mode (that dont exist anymore) and reboot... Im a fool that forget to push the laf stock. Anyway i bought a new motherboard... I think that replacing will solve my problem..
If you connect the phone to USB with a PC, does the PC show anything in explorer or device manager?
If yes, there is still a chance to recover it.
I'm referring to THIS task.
I have not done it before but it could work and you have nothing to loose.
Make sure you get the correct KDZ for your phone from HERE.
Extract the original images with WindowsLGFirmwareExtract
You can find the partition list HERE

Nope man, i only hear the usb plug in/plug out sound of Win7 but nothing in explorer or the lg app on the pc. Its obvious that i have the drivers stock and the others of Android SDK platforms (i used adb and fastboot very uasually when the telephone was funtional).
Anyway thank u all for the help, i had the telephone bricked for the unlocking of the bootloader and i thought that my phone was over, the argument is very difficult to afford on this site and on this device, i sent the telephone at the LG Custom Care and they only told me that the motherboard was over and replace it costs 130€ (im Italian) so i reclined their offer (i have also a Oneplus X) but after some deep research on XDA i made big steps forward and maybe if didnt make the stupid thing of forgot to flash the laf stock, maybe i could be able to rescue my phone. So a big big big Thank to the community of XDA and a infinite f**k to LG Custom Care that they would stole me 130€.
Ps. I bought an LG D620 with the display destroyed for 30€ and ill replace the Motherboard.
Pps. Sorry for my bad English.

OK, sounds good. And what does the devicemanager show?
Is there something like QHSUSB_BULK or Qualcomm HS-USB Qloader ?

Wrong thread.
But, if you have a stock ROM, use LG's drivers. If you have a custom ROM, use Google's drivers.
Good evening, I have in my hands a smartphone lg p778g does not pass me the logo to light following a simple copy of the folder whatsapp internal memory to the microsd (it was blocked after you copy and to restart it and did not initiate more ... it stays in the LG logo when turned on and there does not pass.
I tried to hard reset with vol (+ or -) buttons + home + power but rather than get out the menu of recovery I get the doll android slept with a triangle exclamation and there is no way to enter the menu that tightening no buttons.
Then I looking for information online found the utility tool flash, did all the steps as marked, I installed the drivers perfectly, the PC detects me the phone without problems, but always in the middle of the update (put the mobile mode s / w upgrade ) 50% program lg cancel the process by saying that there has been an unknown error and try try again by disconnecting and connecting the mobile, but no way, I give retry to to try again and again it hangs at 50% and I jump the error screen again.
I wonder if there is some other program where you can do the hard reset this phone than by the official LG utility, or by microsd.
The operating system used is Windows 7 64-bit, disable the Windows firewall and antivirus and run as administrator utility tool flash lg 2014, but always the same. I also tried running the utility lg mobile support tool directly to you directly seeking the most updated for lg p778g firmware, but it's the same as using the lg flash tool 2014, the 50% of the upgrade stops and gives me the message error.
A greeting and I hope you can help me, I need the phone !!
We'd need someone with a p778g. The problem may be be caused by the special branding of the phone, or an encrypted bootloader. Or the internal flash got completely cleared, partitions and baseband rom, which means a full brick. Otherwise flashing stock in D/L mode should work, even if anything else fails. But this goes mainly for LGs official tool working online. With the LG Flash Tool 2014 i had also problems.
I think both tools have to ways to perform the unbricking. Either with the phone put in D/L mode by the user (if Fastboot don't work on the PC), or by recognizing the phone (but with a still running system) via ADB, then auto-switching to Fastboot. And you should also be able to attach the phone when it's already in Fastboot mode. The latter methods don't work on both my systems under Win10. When my desktop pc had been upgraded to 8.1, i performed all servicing of the L9 with my netbook, which was still on Seven.
My last unbrick was months ago, and i don' t know what happens at 50%. It's something important, and knowing it may help to understand the nature of the problem(loss of contact between phone and pc before the actual process starts, errors during flashing...).
It could be like this:
-phone seems to get recognized by driver&tool, that is good
-image gets downloaded(only with the official tool)
-image gets temporarily extracted on the pc(both online and offline). I fear that by completing the extraction the 50% mark is reached, and that no actual writes to the phone can be performed.
And LG's stock recovery, which calls itself "service mode" or "s/w mode" can be mistaken for D/L mode. I'm talking about the D/L mode, which is also present with a custom recovery, but theoretically D/L mode, S/W mode and Fastboot could be used for unbricking

If i was you:
1) Enter in bootload mode using LELUS Method
2) Flash a TWRP 3.0.2 recovery
