use the button combination to get in to recovery, if you flashed an unrooted kdz it should just factory reset you device and it should boot normally.

it did not respond to any thing of that it was only turn on the backlight of the screen only with the boot sound
i was lucky to get it fixed by connecting the USB cable with out the battery but not while holding vol up
this time i needed to hold both vol up and down in same time to make the USB detect the phone and flashed it with the right rom and it worked fine again
so i hope this new info can help here due multi ways i find to get into emergency mode
the normal is plug in USB with out battery while holding vol up but if fail try button combination
to get emergency mode
in my case the screen did not show anything but Windows was able to see the phone at emergency mode and flashed it

LG E400 brick. No boot, no emergency mode.

Hi guys,
I have bricked my LG E400.Yesterday I try to downgrade my firmware with kdz. I receved an error ( kdz upgrade error wparam 100) and after that i turned off the phone.
Now my phone can't boot in any way and my pc won't recongnize it...
Plese help me! :crying::crying::crying:
have you try the combination button?
Vol up + down + Power, then after vibrate press home button
if it can't, maybe you have a hard brick, and you can call nearest service center

I follow your instructions but my kdz doesn't want to detect my phone...my pc doesn't recognize the device...i don't know what to do except throw away it...
Before you throwing it away, did you install the latest drivers?
If not, you can do so by downloading and installing them from your support site or by downloading and installing LG PC SUITE.
After that please open device manager and see if there's anything there with an exclamation or a question mark. If there is, please don't continue and post back what it is.
Only when you see that everything is okay, disconnect your phone, turn it off, enter into emergency mode (by clicking volume up + volume down + power button), make sure that you're in emergency mode (the yellow screen), connect your phone, run Software update [KDZ] (KDZ-Flasher), make sure to set the right type (CDMA / 3GQCT), make sure to leave the PhoneMode in DIAG, browse your kdz stock firmware file, and then click on "Lunch software update".
I'll be looking forward for your comment.
Please don't give up!
I have installed the new drivers and the lg pc suite. The problem is that the phone won't go on emercency mode...
It seems dead.It also doesn't boot and the screen remains black when i push the power button.
When i plug the usb cable in my pc i can't hear the usual sound of w7 but an error sound.The system tries to install the drivers for new device but it can't recognize the phone...

What's happening instead of going into emergency mode, when you're clicking volume up + volume down + power button together? Is it seems dead the same way as you're clicking only the power button?
Did you try flashing your stock ROM again with Software update [KDZ] (KDZ-Flasher)? Is it even recognized in it?
What about the LG MOBILE SUPPORT TOOL? Same issue? It's not recognized?
BTW, you're saying that Windows 7 isn't recognizing the phone? Are you using the drivers that are provided by LG? If not, you can get them here.

Any key combination on my phone doens't have any effect. I try to use LG supporto tool updating many times the drivers but the device is not recognized.
I'm thinking to take the phone to the service center.
If the phone not vibrate when turning on, its a hard brick and u can tell the service... They're propably replace the mainboard

Well, it seems like a hard break - most definitely.
However, maybe one last chance before the service center.
Did you try to look in device manager while connecting your phone? Is there any refreshing while you're doing it? Are there any exclamation or question marks?
The reason I'm asking this is because of this:

That is why I'm not so sure your phone is dead. If it was dead - then why Windows playing a sound when you're connecting it?...

I think the phone is freeze into emercency mode but anyway i take it to the service center...thanks for your help suggestions and help.
You welcome.
Please update how it was.
And if you have the time before you go to the service center, please check the device manager while you're connecting your phone.
It's very interesting, and it might help others too.

If i think correct, you hard bricked you device? (no boot etc)? (i'm not very good in eng)
I gave to the service mine kernel-bricked L3 (no boot, no vibrate, no emergency) and they repair it without any questions.

You might say so, though usually in the service center they'll replace your board in order to get everything back...
Are you sure your phone is dead?
Maybe, like medeno, when you're connecting your phone you're hearing a sound in Windows?

LG optimus f5 (P875), No boot no emergency mode
Hi,
I rooted my phone and now it doesnt turn on, even in emergency mode. But unlike in this thread i hear the windows sound of a new device and in the Device Manager it shows on other devices with a yellow exclamation mark QHSUSB_DLOAD.
I rooted the phone no problem but then i tried to partition the SD card but i ended up partition the internal memory (i think i erased everything even the OS), after reboot i couldnt turn on the phone.
Can you help me?

[Q] [L7][P700][Bricked] Hard bricked Optimus L7 P700

Hey guys,
Yesterday I tried unlocking my phone using the tools provided on this forum, but somehow my device got hard bricked.
It is just laying there with a black screen. It won't turn on, won't boot into recovery or emergency mode. Nothing.
But when I connected it to my PC (running Windows 7), I did hear the sound that it recognised it as a device, it just couldn't find any drivers for it, so I wen't to look into that.
Landed on the debricking method using QPTS on the CyanogenMod forums and I managed to find drivers for Windows 7, so no need for an XP computer!
There were some other Optimus L-series brickers who gave up on the process, but I have still some hope left.
Did all the work that had to be done, decompiled V20D KDZ for our device, converted the first 512 bytes of the partition.bin to .mbn, installed QPTS, and so forth.
Hooked up my phone to the pc holding the volume-down button, and QPTS actually recognised it as a phone in downloading mode!
Then that's where I got stuck. Using the HEX files from this thread, I get the following error:
Code:
Status: Software Download Aborted
Errors: Could not determine the HEX file's scrambling method. The file is invalid.
Do any of you have a clue on how get things working again?
The QPTS tool only lists MSM7x30 (eMMC) as ARMPRG to use for the phone in dowload mode, not the MSM7x27a we are using. Might this be part of the problem?
Any help is highly appreciated!
Can you go to emergency or download mode?
Battery taken out, hold the vol up + connect to usb, connected to the pc. Then you will see in a green screen with emergency mode.
Once your done that, be sure you installed the LG drivers, flashed through kdz.
You can use homero's v20 stock, it's already had cwm and unlock bootloader and v20 baseband.

You should try launching emergency mode some more. Install lg drivers. Take out battery, hold Vol up button and plug in usb. Make sure port works.

I can't turn the device on. When I connect it to the PC, Windows sees the phone as an 'Unknown Device', even with the latest LG drivers installed.
And by KDZ flasher you mean the BC2App, right?

Tried it a dozen times, with different combinations too. Only thing that happens is the sound windows makes when a device is plugged in.
Any chance a method like this would work? If the .img.zx file would be edited for our device ofcourse.
Hey all,
I couldn't get any further debricking my phone myself, so I just brought it to a repair shop. I'm hoping they can do something using JTAG or something.
Regardless of getting my phone working again (hopefully), I would still love to see if we can find a way to debrick hard bricked devices. If we can find a solution, I'll volunteer for writing a tutorial

1.-uninstall the drivers and programs lg l7 on your pc.
restart your pc, and reinstall all programs and drives
for your pc to recognize the phone.
2.-remove the battery, press the power button and volume + and connect the phone to the pc, buttons go into emergency mode
Try this a few times.
you may need to perform step 2 more times
why are you trying to enter emergency mode ?

is your phone in bootloop ? or does it display blank screen ? (black or white)
did you try to remove sdcard ?
did you try to hard-reset ?
can you try to remove anything related to lg from your pc ? (all programs and drivers)
do you have qmemo button on top of volume buttons ? you can try to enter safe mode (most scripts will not work in this mode so you might get lucky)

Removing USB connection while flashing

Hi all,
I have a serious problem with my G2 which I could not solve: I used the new LG Flash Tool 2014 with stock KDZ file, everything was going just fine till I received an error message that LG server is not available, I disconnected the USB cable by mistake from my G2 and afterward I saw that it was in the middle of flashing process (12% was completed). I turned it off and tried to reach download mode again and nothing!, I'm receiving the "LG" logo and nothing- the screen goes black (it is still on).
I tried also to connect my phone to the computer- I received a list of 13 "new" local disks "H" to "T", only "H" disk is available and it's showing "image" folder with list of files.
I cannot reach "download mode", nothing is working!
I hope this is not the end for my G2..
please help me
Thank you so much!
If you could receive all those hard disks then you could maybe fix it with linux/ubuntu if you have it. Search for guides to cOpy the neccesary stuff bacK like the bootloader. I can't really help you atm as i am too sleepy.

Thank you for your reply. I found this on the sticky threads: "[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2".
I installed ubuntu and followed the instructions. when I type the following: "gdisk -l /dev/sde" I receive an error message:
"GPT fdisk (gdisk) version 0.5.1
NOTE: Write test failed with error number 13. It will be impossible to save
changes to this disk's partition table!
Problem opening /dev/sde for reading! Error is 13
You must run this program as root or use sudo!"
My device is not rooted, is this the problem?
Please help me!!
Thanks
@NNCa It says you need to run the program as root on ubuntu.
Just use sudo in front of the commands.
You need to type once your password to use sudo, you can't see the password if you enter it for safety I guess but just click enter after you typed ykur password.

Hi,
I powered off my phone by pressing volume down + power for a while ("LG" logo blinked once and phone was fully powered off).
I pushed volume down + power till I saw the LG logo, released it, and pushed again- and finally I reached the Factory Hard Reset screen. I have pushed 3 times the power, and I have got "Factory reset processing..." and nothing is appeared, even when I'm pushing several times on power again.
I guess this is the end of my G2 :crying:

Sorry for late reaction but i needed to think of something. Did you tryed to use another cable? Did you tryed to do it on another pc? Did you tryed to maybe install LG PC suite and see if it gets recognized? If you have the PC Suite you may need to turn it off in the LG flashtool idk. Can you tell us more like which windows you have?

Hi, sorry to say but you have unfortunately completely hardbricked your device. It happened to me too however I was able to get it replaced under warranty at no extra cost.
What happened was that when your phone was still detected by linux, you had a chance to recover by flashing the correct partitions to gain access to download mode and from there, flash a KDZ to go back to complete stock. However, the files you used were probably incompatible with your variant which has now corrupted your bootloader sequence. I suggest you read this reply by fizzy177 as well as the rest of the thread: http://forum.xda-developers.com/showpost.php?p=51522304&postcount=118
So right now, you cannot do anything as you have already found out, no computer will recognise that your phone is plugged in. Your phone fails to boot when you try enter the download mode and it just freezes on the splash screen which looks like this: http://www.lg-phones.org/wp-content/uploads/2014/03/image2.png
What's meant to happen is your phone should load past that initial splash screen into this http://www.androiddunya.com/wp-content/uploads/2014/01/LG-G2-DownloadMode.jpg which accepts KDZ flashing and warns the device has been rooted.
So it's a blessing that your phone cannot boot as LG cannot find out you have voided warranty and you will be able to get a replacement free of charge.
Issue was solved- device was fixed under warranty

I just want to update you all that my device was fixed under warranty! (motherboard replacement)
Thank you all for help and great support, this is a great forum with great community :good::good:
Hello
From past 2 weeks i am wondering on internet for a solution . Hours and hours of surfing and articles but still
Hope some one solve this issue.
Okay. First i m using LG G2 F320 K update to lollipop . Non rooted. It was working fine . I can transfer files in MTP .
But about a month ago i get an update for my phone . And after some days i need to transfer some files to my phone , i wonder when i connected my phone to computer nothing happened . No notification on mobile for changing PTP MTP option . Also nothing happened in Computer device manager..
From that day i am unable to connect my phone with windows 10. It always charging mobile.
I uninstalled all drivers in device manager and installed from LG website. I updates windows N and NK MTP update from windows for windows 10.
I changed different data cables and different computers and different ports . All stuff i can do. Still no luck.
When ever i plug USB data cable it always put my Mobile on Charging . No notification on Mobile. Also i go in setting > storage> and there is no option in upper right corner to select USB PC connection .
I am in developer mode and debugging mode is on also. Also USB tethering option is Disabled .
Kindly some one help me regarding this.
LG G2 F320K updated to stock Koren lollipop 5.0.1 . Non root.( i updated lollipop in April 2015)
Issue i am facing is no notification for Charging/ MTP/PTP Usb Debugging on mobile notice bar when i attach my phone using USB cord with computer. Also in computer device manager nothing happen. Even i checked on windows 10 , 8.1, 8, 7 .
I remember it was working like charm 4 weeks before I can change MTP PTP or Charge only mode by selecting notification when i attach it to my laptop. I can transfer files can use LG PC suit .
Then i received an software update like 40 mb and i updated my mobile. That i remembered.
After that 2 weeks before i need to transfer some books from laptop to my mobile. When i plugged my device there no notification to select MTP mode . Also there is nothing happened in my windows 10. I looked in task manager. No yellow icon in computer task manager for driver thing.
Laptop is just silent and mobile is just on charging .
Then i go to setting in LG and looked for USB PC connection settings. I wonder there is nothing . Settings > storage > 3 dot in upper right corner.. it suppose to be there . But here is no 3 dot in storage. Then i looked into share and networks in android setting and i found that USB tethering. But its faded mean it is disabled and i am unable to use this feature also.
I tried on different computers different cables , original, but nothing. Always when i plug usb mobile went on charging and in all computers nothing happen in device manager.
USB debugging is on.. I factory reset device 2 times. but useless. Also i uninstall all drivers from my laptop and then reinstall drivers from LG website also i tried google drivers , ABD, different ports. Nothing nothing happen.
Also now if i try put mobile on download mode by turning device off and then push + vol button and then put cord in mobile . No download mode also it went on charging. Well charging from laptop or from charger is okay.
Hope i explain all.

does the lg logo show up when you conect usb?
If so you can try to remove the battery, hold the button combination for recovery and conect to the charger or usb. Dont press power button at all. Just the combination for recovery.

you may have a hard brick, that cant be fixed. Only if you send your phone to LG.

well if you can get it in download mode some how you can flash kdz.
But dont know how.
You can try to remove bat and hold the vol down button. (I think thats how you enter download mode) and conect the phone to the pc.
Nvm if it wont show download mode on the phone just try flashing kdz.
