I have an LG G2 here that my friend managed to get stuck in a boot loop. I have tried installing a fresh ROM & once i hit restart the phone boots then shows LG logo and next thing you know I'm back in TWRP. I have tried putting the phone into download mode with no results also it just simply opens back up TWRP :/
If anyone can help me out with this i look forward to hearing from you, as of right now I'm completely stumped & she is without a phone!

I was able to get back Download Mode & Install a Custom ROM. Now I've run into a new problem. She now has a half working rom... No Data (APN's wont save), Computer doesn't recognize internal sd size so no transfers can be done unless using adb to push. Lastly i tried going back to stock by installing the kdz but for some reason the program wont start the process it starts installing divers then nothing after that it doesnt startan install
Anyone have any ideas?

Hi Guys,
Having major issues with my LG G2 D802 (international version).
I have the OTA update to 4.4 already installed.
Im rooted with the TWRP Recovery installed - v2.7.0.0
Noticed i had a software update earlier from LG themselves so decided to select yes and thought that it would just update LG's stock apps (camera, Quick Remote etc) - the phone rebooted into TWRP Recovery and wouldnt reboot from there, i have a back up installed on my device but even when trying to restore the back-up it wont reboot past the TWRP Recovery screen after installing the back-up
I have tried to boot into safe mode so i can install the KDZ and start from scratch but the phone wont even boot into safe mode. I power device off using TWRP Recovery - i then press volume up and keep it held down but when connecting device to pc with USB i immediately get the 'LG' splashscreen instead of the safemode
I can't get further than this and i'm pulling my hair out - any fixes or suggestions about how i should go about sorting this please?.......getting into safe mode would be a great start
Thanks for any help
Update - I've installed all necessary drivers on my pc (had these before but downloaded again anyway just to make sure) and when i connect the LG to the pc i get the 'bim bom' sound notification telling me something has been connected to my pc but the LG doesnt show up anywhere under computer
Whats going wrong here! Any suggestions please?
Hi there!
So I rooted my LG G2 (D802, 4.4.2, Stock, used ioroot) yesterday.
I intend(ed) to flash the Optimus G3 Rom, in the start post they recommended to flash cmw/twrp via "Simple Tool 3.2" (http://forum.xda-developers.com/showthread.php?t=2633941). After doing so (I used the automated version, not the manual one) I got STUCK ON THE BOOTSCREEN. There is a notification popping up for a few seconds in the left upper corner which lists several errors occurring:
BOOT CERTIFICATION VERIFY
SECURE BOOTING ERROR;
CAUSE: BOOTCERTIFICATION VERIFY
along with the following numbers listed from top to bottom: 710, 760, 810, 860, 910, 960 (I just noticed, the numbers can vary, but always follow the same pattern...)
after this message, the screen fades to black, I think it it is still running though, since it takes more than 10 seconds to reboot the phone by pressing the power button. I still have access to the button down/power button combo which leads to a factory reset setting, but it doesnt do anything for me since I still get stuck at the lg boot screen.
I
Atm I dont what to do! Enter download mode and flash something? I'm seriously kind lost here. So, thank you for your help!
Cheers

Thanks a ton!! Finally I can put a name on the problem (bricking...)- Ironically I never mangaged to get there in 3years of samsung flashing but got there within 15mins of flashing on the LG G2. I guess it's true what they say about samsung devices, as hard to brick as a brick...
I'll report back if it worked...
Weeell, as it turns out my phone isn't recognized by my pc (Win 7) anymore...I literally can't do anything. Any hints?
I can use the Tool, but it's always trying to connect to my phone without success. But when I connect my phone to the computer it opens a dropbox window (import photos) and several windows partitions, which it tells me to format...

Hello everyone!
I really hope I can find help here. I wanted to install Cyanogenmod 13 on my LG G2 D802 32GB. In the end I think I bricked my phone. I want to mention that I already searched for help on the Internet and tried many tutorials, but nothing helped.
First, I rooted my phone using this One click root method (before, I tried doing that other ways but it didn't work). So far, so good.
Then, I installed TWRP via Autorec. And here came the first problem. I booted into recovery mode and then the phone wouldn't start anymore. I started getting "Security error" along with Lg logo, when I wanted to turn on the phone. Actually I can't remember if I wiped everything in Recovery mode before or after getting this error, but I did anyway. Then I didn't get this security error message anymore, just stuck with lg logo.
Anyway I was still able to get into recovery or download mod, so I tried installing CM. But I couldn't acces my phone memory through PC and I didn't have CM installer zip on the phone. I tried copying CM installer into the phone using ADB push command. It did copy, it said it succesfully installed but since then every time I turn on my phone Lg logo just blinks for a fraction of a second and the phone will not turn on. The screen is black, but it remains "on" (there's nothing on it but you can see it's not totally turned off).
After that I tried every tutorial I could to install CM or stock ROM. I tried downloading different LG firmwares, including one found on a page where I had to enter my IMEI. But it's always the same problem: when I use LG Flashtool ( 1.0.54 ) it gets stuck. After clicking on System Upgrade I'm not asked about the language (as tutorials suggest), but it just opens LGMobile Support Tool, which says that my system is up to date.
OK, I think that's all I can say. So, the main problem is that I cannot use LG Flashtool, which is neccessary to install stock ROM in all the tutorials I have seen. Of course, I would like to install CM 13 still, but now th emost important thing is to get my phone to work again, even on stock system.
I hope we can solve this problem. Thank you all in advance!
Can you boot in download mode?
If you have download mode you can easily reflash stock

If you cant get to download mode you have to reflash all the partitions here is thread

Thanks a lot. I followed the instructions in the first post on the first site that you linked, using kdz file. Everything seemed to go well and I was already happy, but... It seemed that the stock flashed (on the computer it said that the installation was correct, on the phone the screen showed Update Software and it went to 100% percent), then the phone restarted and started updating apps for Android. And that is normal I suppose. But then, after it finished, it turned off, turned on and started installing those apps again. After that it turned off. When I wanted to turn it on, it showed me LG logo and then android logo for a fraction of a second. Then sometimes it would turn off completely and sometimes turn on again and show logos again. I assume that's what is called bootloop. So I followed the tutorial which said I should do factory hard reset. I entered the screen (power+vol down buttons), confirmed two times that I want to do the reset. It said the reset will start automatically, but nothing happened. The phone just turned off immediately and the same situation with logos (Bootlooping?) appears. So the problem now is that I cannot factory reset the phone.

I'm having a similar problem on my vs980 except I can't access recovery anymore but everything else is the same.
Edit: I actually can access recovery
You messed up pretty bad before you fixed a problem, you created another.
Have you tried to go back to stock using downoad mode and kdz?

OK, well, this is strange. The phone is working again, but actually I have no idea why I downloaded the tool from your link, installed it and ran. Then, following the yt tutorial, I went to the step where I was supposed to "look and remember the disk number that have so many partitions". I didn't anything there, though. And then, all of the sudden the phone started updating Android apps and then turned on as after factory reset. Weird, but it's working fine
By the way, can someone post a link to a tutorial on how to install Cyanogenmod 13 on LG G2 D802 32GB? I would still like to install it, but I want to avoid all the problems that I had now. So is there any good step by step tutorial that I could use to install CM?
Anyway, thanks all for help

Sure.
Download the rom from cyanogenmod website and put it on your phone memory.
Download Gapps from opengapps.org and place on the phone memory.
Go to recovery.
Make a full nandroid backup( all the partitions) , wipe all except internal storage.
Flash the rom along with the gaaps zip.
Reboot.
Hello, I own a Lenovo A6010, I recently tried to install a custom rom from a forum in this website, as i am newbie to all this, I think i screwed somewhere. Now my phone is stuck on boot screen. I cannot even start my phone in recovery mode or the menu that takes you to recovery mode.
Before flashing i had taken a backup of the dalvik cache and system and data and all those options available in the backup option in twrp which kept on my pc. Now i dont have any idea what do.
I even downloaded the stock rom of my phone from some website, but it was available in a rar file.
When I connect my phone with a cable while pressing the volume down button the same boot screen pops up and my computer starts to install device drivers. I think my phone can be brought back to normal, but i don't know how.
can someone please help me with some suggestions on what to do with my brick.
Thanks in Advance...
Warm regards
Do you have twrp installed? And by what method exactly did you try to install the custom rom?
Edit: Nevermind. Didn't realise this was a year old thread
