I had Mahdi Rom for my LG G2. I went into recovery mode and installed a Kernel. When I rebooted, I was stuck on a boot loop. I tried to go into recovery mode, but first it asked to do a factory reset. I hit ok. It then brought me to recovery. It says that I am unrooted. I am able to go into download mode, but my computer says something is wrong with the driver. For some reason LG Support tool thinks I am in Optimus Rom and says everything is fine. Any advice?
Install proper drivers on your computer and return to stock using the .kdz method that's stickied in the G2 General section.

Hi.
I have a Vodafone Germany LG G2 with stock KitKat.
My story:
I installed root and recovery. Then I tried to install the OTA, doesnt work, tried it with LG PC Suite. Boot certification verify error.
Recovered all with this guide:
[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2
http://forum.xda-developers.com/showthread.php?t=2582142
Then flashed an open LG G2 kdz and all was fine again, but...
no Update for me with knock code.
----------------->>>>
So i tried to flash the original Vodafone KDZ in Offline mode. I get an error at 15 percent and it wont work. So i restarted my phone, but i only had a black screen. Nothing worked again (no download, no recovery). Ok, plugged in in PC and woha, broadcom device detected. Back to ubuntu and recovery again (see above).
After that, i restarted my phone, but no recovery was there... only the lg logo. Everytime. Again: No Download, no recovery. Stuck at bootloop every time. Factory hard reset can be called, but if i confirm, "Factory reset processing" appears, now for ~30 minutes. Is there a way to fastboot or to another state than that?
Any idea?
I'm sorry if there is a post for this already, I have been using this website for a while and until now never had to post because all my questions were answered. This time I am not able to find an answer or even a thread with the same circumstances as mine. I rooted and installed a custom rom but didn't like it. I tried going back to stock but accidentally wiped the phone so the backups and the roms were gone. I had TWRP installed but it wouldn't allow me to sideload via adb and when I tried to enter download mode, it would enter it but go to a screen that just said firmware update and stayed stuck on there. So I went out and bought a OTG usb cable to read the rom off a flash drive and I installed it but now instead of going to recovery it goes to a black screen that just says fastboot mode udc start. Download mode still does the same firmware update screen. Any help would be appreciated, thank you.
What rom did you try to install what software version were you on

I'm on the latest software and I tried to put the newest stock I could find but honestly I might've made a mistake since my PC is loaded with different roms and files from all kinds of phones and software versions.

I just saw this. I have done the same thing. But I have been able to recover with TOT file. The trick to enter download mode is to hold the volume up button when you power on the phone. If you can get the phone to stay off, then hold volume up, while holding vol up plug in your data cable. You should get DL mode. If you do this while the LG Flash Tool is open, then go to control panel and find the COM port for the LG phone, open properties and advanced, change the COM port to COM41. Once that is done, also once the flash tool files are loaded and the COM41 box says ready, unplug your phone then replug your phone. You may have to also hold volume down here, I can't remember. But the first time is to let the drivers configure. The second time lets the flash tool see the COM port and it should start flashing. It will get around 80% and reboot. The flash is done and the tool will eventually report an error.
I installed the KK baseband as instructed, even also came from the stock ZVC update, rooted via IORoot25. It's a shame as I've heard great things about this ROM.
Hope that helps.

hey there,
I had AOKP on my lg g2 and i've decided to revert to stock, so i followed this guide and successfully returned to lg stock rom, after that I've tried to run ioroot script to root my device and after that the device is stuck on recovery mode with infinite progress bar, i can go to download mode, can't go to recovery mode or to factory reset mode
what can i do to solve it out?
i have lg g2 d802, i have installed TWRP and when im updating KK via OTA it backs to twrp.
and im try this code in the link http://forum.xda-developers.com/showthread.php?t=2451696
but my phone restart and just stuck on lg logo and blinking green/blue
then i have enter download mode and want to flash KDZ,
when im running KDZ, my computer says cannt detected and in my G2 screen is firm ware update
please help me :crying::crying:
You can't take an OTA w/ a third party recovery like TWRP or PhilZ CWM Touch installed. If you can't flash the *.kdz or *.tot file from download mode, then you'll need to revert to this method...

If you can get into recovery, then you can just flash another ROM or restore a nandroid. If you don't have a ROM on the internal SD, then you can use ADB to push a ROM to the SD while in recovery.
i can enter TWRP, and i can enter factory reset. then what should i do?i dont have a rom in my internal storage
i can enter download mode and i can enter TWRP. but i dont understand... sorryy im totally newbie.

Flash back to stock and don't touch anything. http://forum.xda-developers.com/showthread.php?t=2432476
All you need to do is SEARCH and you will find what you have to do in order to get the phone to boot up again.

when flashing KDZ, my computer doesnt detect my LG G2 and cant continue..
and now just stuck in logo lg with blinking LED
Phone was stock 4.4.2 from sprint. I did root the phone. The thread said the auto tool would install recovery so I did not install it beforehand.
I ran OneClick_ROOT_RECOVERY as described in a thread on the Xdaforum by accident. It says for d802 only; my phone is the ls980 sprint. Didn't notice d802 at the top of the thread. Phone is now stuck in fastboot and reboots into fastboot. Phone does respond to fastboot commands from command prompt. Phone was running 4.4.2.
I installed openrecovery-twrp-2.8.5.0-ls980 from fastboot hoping if I rebooted it would launch into twrp. It just keeps rebooting into fastboot.
Tried LG flashtool, can't get phone into download mode. It goes into download briefly, then immediately goes into fastboot. Tried using lg flash tool, can't because phone will not stay in download mode..
Tried factory reset mode, it fails with 'certificate error'.
I'm totally stuck.
There are some repair services on eBay that I have used when I bricked my phone it cost about $15-20.
