Hey guys.
So here is my problem:
I want to install a stock rom on my l7 because i don't like cm 10.2 anymore.
Here is what i tryed:
To flash it via CWM (i found a flashable zip based on the stock rom) but somehow it don;t shows me errors but the installation time is about 20 seconds.. (i don;t think it installed it)
after i make the factory reset it's still stucked at the LG logo.
To flash it via kdz updater (HERE IS THE PROBLEM) my PC is not recognizeing the emergency mode ( vol + and power) but i can hear when it connects and disconnects (pc usb sound and it takes a couple of seconds) and the phones screen flashes for about 0.5 seconds (only when i connect it to the PC).
I do have the lattest drivers for my phone and i ran the kdz updater perfectly but it says no phone found
I made it before but now i don;t remember how i did it.
Please help me, I will be gratefull!
UPDATE!
I had to format the phones SD card and then my pc recognized the phone and finally flashed a stock rom.

Hi all,
i have a problem, got a new Lg L7 P710, and i wanted to jailbreak/root etc. but i think i failed with it.
also i tried with KDZ updater, and installing LG modem and Lg Androidnet usb serial port (com6)/ and installed all those drivers needed. My SD card is still in the phone, but i can't see it in ''my Computer'' when my LG is plugged into mine laptop.. also the rooting part its failing.. btw my yellow screen for emergency is not normal, its kinda with stripes, and i can't see the ''emergency' 'word on the phone when it is yellow, sometimes it goes blue screen with stripes...
i don't think its a hardware problem, but i accidently deleted everything also in SD card, and in the phone self, its just like a Stock peg...and also i lost my warranty in 3 weeks -_-'', i can't do anything, only plugg it in mine laptop, and i hear a noise sometimes, dat it is plugged in, but only in ''Device manager'' I also read some other forums, with bricked or unbricked, or ADB ( also tried with this and CMD) but didnot recognise mine phone... as you can see, my phone is connected to mine laptop ( see pictures)
any solutions/help please? :crying:

Hi, I have same picture on my L7 display and I dont know what to do. I tried to reflash over KDZ, it seems that phone is installing SW before first reboot. After reboot KDZ updater stops working Any suggestion? Somewhere I found, that only way is to use JTAG.
...
I have the same problem,one of my frends is trying to put kit kat on l7 p710,but he is so stupid... he download and put firmware for l9... now i trying to repare it i can't find the phone in device manager... anyone find a solution? please HELP!!!
Hi,
I'm opening a thread because I just couldn't find any way to unbrick my device. In the past I used the FlashTool2014 to go back to the stock LP KDZ for my device.
I was in the stock rom when I decided to mess with the build.prop and then went back to the stock backup. When I restarted the phone it showed the LG logo, screen went black and never booted android. I could access the stock recovery but the Factory Reset won't work.
Then I decided to go to download mode, it connects and the PC detects it as an MTP device. I open the FlashTool2014 and it detects the device OK. When the LGUserCSTool opens it says the Upgrade stopped due to an error and the device stays on 0% and shows USER B70 in the console. I can press Retry, turn off the phone and reconnect in Download mode but the LGCSTool just wont push the firmware.
I suspected I had a driver issue so I tried using a clean win8 install I have for this purposes without success. I cant flash with the TOT method since the other LG Flash Tool wont detect the device in download mode when connected to the pc. This is really weird.
Any ideas ?
Thanks in advance.
EDIT: Solved with another tot file (almost lost all hope), took me 20+ hours to download it, I'll better make a backup of this files on the cloud. Still having problems with STOCK firmwares but could install TWRP and get CM13 which doesn't give any problems.

Hey guys.
I'm issuing a serious bootloop problem with my D802. I need help.
How things evolved, listen my story.
1- I was using Bliss ROM 6.4 , after a new update my cellular data connection lost. So I back to stock lollipop.
2- I back to D80230c with using LG G2 Stock Firmware (Go Back to Stock) http://forum.xda-developers.com/showthread.php?t=2432476 method. I got a KDZ file and I flash it.
3- Then I used [TOOLS] One Click ROOT+TWRP Recovery for Lollipop Stock Firmware http://forum.xda-developers.com/lg-g2/development-d802/tools-how-to-install-twrp-bump-d80230a-t3072186 to get root and TWRP.
4- Lastly, script broke on somewhere and my g2 stuck at bootloop.
- When I connect the phone to computer with usb cable, I am getting bootloop. [ LG logo keeps appearing in every 2 or 3 seconds. ] and it keep going.
- When I connect the phone to the charger with usb cable, I am still getting bootloop (lg logo thing) 5 or 6 times then I see Firmware update screen. Lastly, phone get stable and it holds firmware update screen as long as it charged.
-When I disconnected the phone from charger and connect to computer, it begin to restarting and bootloop continues.
Most importantly, my phone does not respond, if its not connected to computer or charger. I mean, it should connect to computer or charger with usb cable to respond hardware key commands. ( download mode, recovery mode, or hardware key control mode ) Btw hardware key control mode is korean language)
I tried LG PC Suite resolve update errors , I tried .tot and .dkz method for flashing rom. ( Device goes to bootloop when transferring data begin from computer.) These methods are failed for me. I did not try fastboot mode.
Maybe someone can help mw, I issuing this kind a problem in three years of android user.
Sorry my English :/

Hello guys,
So I bricked my D802 , how? first it was bricked because of a wrong version of TWRP, untill here no problem, i tried many tutorials on how to go back to stock rom, then i found that it was a Qualcom thing problem, so I found that tutorial about replacing the .img files etc... , pretty easy, i could enter the recovery menu, but it had no rom, i downloaded the stock rom kdz file , started flashing it, then, for some dumb reason the flashing stopped, I ... plug out the usb cable... I didn't notice untill I saw that the program froze, and now the phone is stuck at the LG logo, impossible to do anything, pc doesn't recognize it, can't go to recovery menu, can someone help me please? or at least tell me if I should just throw that phone or keep it if it has a chance of living a bit longer

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.
Hello guys!
Unfortunately I have managed to full brick my phone which has worked without any issues for more then 3 years.
My story:
1. Phone started to have random restarts, basicaly, when phone lagged little bit - it restarted phone.
2. When I did manual restart, I got into bootloop and could not get out
3. With a heavy heart I did a factory reset. - Problem with random restarts ontinued together with random bootloops.
4. Did maybe 5 more factory resets, nothing happened.
5. Found a tutorial to flash new firmware.I was on 5.0.2 D802 30d so I used same. (PC suite could not find my phone and LG support tool always freezed on SW install)
6. I used LG Flash tool with normal flash. - used *.kdz which I have downloaded via LG support tool - checked size with dl from source from xda and they were same so i used it.)
7. All success, but device keep restarting - i think no bootloop anymore.
8. I did full flash again with LG flash tool so have a clean install and hopefully fix everything.
9. Suddenly mid-install my phone auto-disconnected from laptop and even with Retry attemps I wasnt able to get it running again. Then my phone restarted itself and that was it.
Now I cannot go to recovery mode, I cannot go to Download mode, all I see is black screen (turns some light on little bit underneath but no data visible).
Also when connect to my Windows 10 laptop multiple discs trying to load and trying to format disk. (one of them contains folder image with some files inside).
I dont have root, I dont have any other tools installed on my phone, just a normal user.
I tried to download adb but i dont understand it much, and also it cannot find my device.
Is there any way how to still fix my phone or is it completely lost
If so, I please you for a dummies step-by-step list .
Thank you so much in advance. :crying:
So good news,
I managed to load img back with dd application.
My Download mode together with factory reset is working.
I have tried to flash it with LGUP and even with some accused usb disconnections I probably managed to flash new lollipop to my phone.
Now it is optimalizing apps to load android correctly. Only issue I have is low battery, it always drains it too quickly so it cannot load properly.
Any idea how to charge the battery? Every time I connect phone with usb cable it starts up into boot, possible bootloop (cannot say if it is because of low battery or real bootloop)
Thanks
Dude try to install crdroid 7.1.2 nougat rom of d802 this will fix your battery problem
root it and install TWRP with srktools 2.0
this is best way to root G2 5.0.1 lolipop
you can also use LG One Click Root to obtain root then don't update su binary and install Autorec of you model to get twrp
