[Q] Can't get out of emergency mode (NO USB DEBUGGING MODE)

Hello all,
I have big problems with my L7 P700.
I rooted it two month ago, even that time I was stuck at yellow emergency mode, but using some instruction (disable LG modem) I was able to boot phone again.
Today I believe I have totally different problem.
What I did, I found stock firmware 4.1.2 and LG drivers, I installed it. Restarted phone and pressed Volume UP + Power. Phone went to yellow emergency mode, ok... Then I tried to use KDZ_FW_EN, phone was not seen. I restarted it and it booted ok to system. Turned of again, went to emergency mode than I opened KDZ_FW_EN again. I tried to read phone information, the program chrashed. I opened it again and tried to flash firmware. There were errors, and I am pretty sure phone wasn't even properly connected to PC!
So if you don't understand me I will repeat again.
I went to emergency mode WITHOUT USB DEBUGGING ON (I disabled it one day, I remember, this time I forget to turn it on). So Under device manager I see only USB composite device and LG Modem, disabling modem isn't a fix (like two month ago when I rooted). This time I can't use any of flashing tools cos I am not in debugging mode =(. The only thing I don't understand is how I was able to destroy my phone if it wasn't even flashing it (port number was -1, some wparam 100-1000 errors, i closed program in the middle but it wasn flashing if I wasn't in debug mode?)
Phone is rooted and stuck at emergency mode, without usb debugging and hard reset bring the emergency on (BOTH VOLUME BUTTONS + MENU)
Anyone?
Yes, I had the same problem a few months ago. Try install firmware stock V20D without battery and then connect phone via cable USB to PC but turning on Emergency Mode. Next, 3GQCT and CS EMERGENCY. Of course you can change port USB. Try reinstall KDZ and drivers. If you have Windows Vista then that's the problem. I'm sure that this situation will be resolve.
Ok I made it!
Don't know how, maybe it was working all the time. I've seen that phone is connected thru Ports (COM & LPT). Opened KDZ again, even that the install for firmware usb driver failed. I again tried to flash, again there were errors (wparam,...) and port -1?, I just left phone connected, yesterday I unplugged it! After 10minutes phone restarted and here is 4.1.2 and all the data is here!
Don't know what I was doing =)
Thread can be closed now!
Great!

[Q] Lg F320S Stuck on bootloop

Hi all,
My phone is bricked with following syptoms:
1) Not being recognised in download mode
2) Adb without root acess (unable to push files)
3) No recovery
Detailed problems
I have a (Korean) Lg G2 (F320s) and its stuck on bootloop. It goes into download mode with Vol + with plugging into computer but the computer doesnt recognise it as attached...no sound, nothing in device manager and no found by Lg Flashtools or Kdz updater.
When simply turning on i connect it to the PC it shows as an ADB interface device and i have ADB but no root authorization (my phone was rooted before).
Lastly when i try to enter recovery it just flashes a couple of times and goes black...back light still on. In this mode when i connect it to PC it shows up several drives and phone comes up as Qhsusb_bulk device. I read a thread using UBUNTU to repair this but it wont work for me....the PC just hangs up and Ubuntu is unable to mount the drives (Even after the settings from Dconf Editor).
Please help i have been stuck for days
Please help
Please help ppl... is there a possible solution to the problem..?? JTAG maybe??

[Q] LG L5 E610 bricked

Hello. Few months ago I installed unofficial Cyanogenmod 11 on my E610. After updating baseband it worked perfectly. After some time I decided to restore my phone to the state after installing CM11. It worked no problem. Today I wanted to do the same, and after installing SuperSU and Texdroider DPI I rebooted my cellphone, and it stucks on the cyanogenmod boot logo. If I try to get to recovery mode it stucks on the LG logo instead of CM. Hard reset is not happening at all. I tried to connect my phone via LG User Support Tool and install kdz firmware, but no luck. Although when I connect my phone without the battery to my PC i hear the "ding" windows sound, and phone exists in device manager. It also creates some disc drive in my computer, but unfortunately it's empty. I think textdroider has changed the build.prop file, so the cyanogenmod is not able to start at all. Is there any possibility to get to the build.prop file and change it, so phone will start? Or maybe somehow I can reset my phone or reinstall firmware using my USB cable without entering usb debug or recovery mode? Thanks in advance for any idea :crying:
Put your phone in Emergency Download Mode : switch it off, hold volume down button while plugging USB cable (already connected to the PC).
Then use the Support Tool to go back to LG ROM

Click to expand...
Click to collapse
in these cases emergency mode should work
removing battery sim sd etc... connect your phone to the pc throught us cable pressing vol- it automatically boot into download mode and you can easily use kdz.
make sure you have the last driver from lg websites else kdz wont find your phone, and set emergency option in kdz everything else it similar to a normal flash

PC doesn't recognize my phone (cannot install ROM)

Hey there guys!!!
Can you please help me with this?
Yesterday i tried to install a new ROM on my LG Android phone (My LG phone is not working properly, it has a reboot loop). I tried to do a factory reset without success -> the dead Android logo appeared :/
I put my phone in Download Mode and connected to the pc but Windows does not recognize my phone.. it says: "USB device not recognized.. the last USB device you connected to this computer malfunctioned and Windows does not recognize it"
I do not know what to do now.. when i try to flash a ROM with the LG Flash Tool it fails because LG program does not recognize my device..
PS: LG Support Tool recognizes my phone (it shows the model) but i cannot flash a ROM
Thanks!!:fingers-crossed:
