Really urgent problem and strange problem after flashing kitkat bootloader - G2 Q&A, Help & Troubleshooting

I have a really urgent problem, I have g2 lollipop stock and wanted to go back to kitkat, I had the recovery installed so I flashed the JB bootloader and rebooted phone like on the guide.
Now of course the system is unable to boot (black screen and reboot when trying to shut down) but I can't go to recovery with power+down and in download mode my 2 pc don't detect my phone (tried with 3 different cable) so I can't use lgflash 2014.
I really need the phone in the following hour but I can't figure out the problem.

Bootloop problem, no recovery, no download mode (Non rooted and No custom recovery)

Hi, I just bought an LG G2 D802 20B Model a couple days ago, yesterday I wanted to downgrade to 4.2.2 and I ended up bricking the phone.
The phone is non rooted, doesn't have any custom recovery, and not recognized by adb even though i installed all the drivers ( koush drivers, PdaNet, Lg drivers ...)
At first I flashed with .kdz file and it ended in bootloop, I tried to factory reset but it doesnt have any effects with the stock recovery it only shows the green android bot and blue progress bar and then restart in 3 seconds and reboots to lg logo and start looping.. After a restart the download mode didn't work anymore it showed me fastboot error, I searched for the tutorial that actually worked and I flashed with .tot method but there is still bootloop and the download mode is stuck at the image attached. The phone is not recognized by neither windows or ubuntu therefore I can't use adb to fix the partitions.
Can any body provide me with a solution? The phone is still new and it will be a shame if its transformed to a brick in 3 days :crying:​

Thanks for your reply, however the phone is not recognized on windows neither on ubuntu therefore this tutorial can't help ...
I am in the exact same situation.
Mine is a D802 32GB Hong Kong model. I stupidly ran AutoRec which soft-bricked my phone. Managed to get Download Mode working, then flashed 20C and 20B which bootlooped. Then I attempted to flash 10B, which got me into this exact state:
Download Mode not working (only shows "Download Mode", does not go to firmware recovery screen, not detected in Win/Linux)
Factory reset (Power + Vol Down) can go to factory reset screen, after factory reset, still bootloop.
Once in a while, I also get the Android icon which then disappears after a few seconds and goes to LG logo again.
If I plug the phone in and do a factory reset, Windows detects the LGE AndroidNet modem, and Linux will detect cdc_acm USB Abstract Control Model driver. Flash Tool and LG Mobile Support seems to detect the phone and attempt to flash, but the phone restarts after a short while.
I have no idea what else to do

Bricked LG G2 D802

Hi Guyz, so i managed to brick my phone yesterday. Was running Optimus G3 and decided to flash CloudyG2 3.3. Followed the instructions did a full wipe but when rebooted LG logo would flash for a split second then screen goes blank. The screen is on because can see the back-light but nothing boots. Tried a couple more restarts but the same thing happens. I did take a TWRP backup prior but when i enter recovery mode and restore the backup, when it reboots i get the LG logo then the android animation but then it freezes/stops on the Android text.
I then tried flashing stock rom via LG Flash Tool, downloaded both kitkat and lollipop kdz files, entered download mode on phone and got the firmware update message, went through the process of flashing with the flash tool but when it comes to the software upgrade part, it gets to 2% then fails. with a message - Upgrade stopped due to an error. I get this message when trying to flash both kitkat and lollipop kdz files and i have tried on both windows 10 machine and windows 7 laptop.
As i have access to recovery i have tried restoring backup many times but it just gets stuck at after the android animation, i guess my next step is to try the tot flash method but im struggling to find a clear guide on how to do this so any advice would be helpful.
Cheers, Justin.

Thanks, actually shortly after i posted question it fixed itself... i tried flashing lollipop again, the software upgrade started and it got to 2% then error. I left the LG flash tool open with the error on screen, disconnected phone and rebooted the phone... it went past LG logo and got stuck in boot just after showing android animation, so then i plugged in phone (wanted to see if could access phone via windows whilst stuck at boot) and after a couple of minutes the software upgrade window started on my pc so checked phone and it had switched into Firmware Update mode and was updating... so all good now!! Lollipop has installed and phone all working.
^^^ This may help someone with similar problem.
Thanks,
You should've flashed the kitkat bootloder before.. If you want to go back to cloudy ,flash the kitkat bootlader again..

Phone "bricked"? Unable to detect phone via adb, or go to recovery. Suggestions?

Phone "bricked"? Unable to detect phone via adb, or go to recovery. Suggestions?
Hi,
I was trying to sideload the new MM update over adb. Somehow it got stuck at 49%. So, I rebooted my phone and tried again. MM update was getting stuck at 49% every time.
So, I tried to reboot to recovery to install the update from there. But now, my phone is not going to recovery mode. It just shows me 4 options (Reboot, Install update, Wipe data, Power off). And install update does not allow me to select sd card, so I cant even choose the update.
When I try to boot normally, it just shows the first screen (Lenovo in white, with "powered by android" at the bottom).
I tried connecting to PC, but my phone is not detected by that K3 Note manager tool, or by Pda.net tool. So, I am not sure, what I can even do next.
Solved the problem. Had to flash the whole thing again using SP flash tools and old stock roms. Newer rom was not working for some reason.
Finally on 6.0. Sadly, lost all my settings.
Hey bro tell me how to flash the MM STOCK ROM I got stuck at 49% it shows install failed & gives only option for BACK & when I does the same It goes to Main Recovery screen. I don't know what to do even. Help me please
I basically ended up flashing the full thing from the beginning. See the attached text file for the steps I followed. Finding the tools is easy, just type the tool name on google.
Tools needed:
mt65xx drivers
SP flash tool
Stock rom (only the chinese version has full rom, so you have to download that rom).
After that, you can update the stock rom to marshmallow using the recovery.
Lenovo k3 note bricked. Unable to detect it via pc , On a bootloop , SP flash tool
I replaced recovery from twrp v3.0.0 to stock recovery using its image and my phone is in bootloop and when I boot my phone it shows the first screen . After a lot of research I found its the bootloop.
But the main problem is that SP flash tool cannt detect my phone so I am unable to flash it again and install new recovery in it. I have installed k3 note manager, pda net ,ADB driver and many other but still it's not working.
Can anyone help me out regarding this problem?

S4 AT&T(I337) Recovery Boot Loop - Need help!!!!!

A client brought in her phone (S4-i337) that was in recovery mode, at first i thought it was something simple but not really. At first i did a wipe data but it couldn't boot up instead after rebooting, it went back to recovery mode. Surprisingly, this phone boots up normally when you try to boot to download mode. As in, when i press Volume down + Home + Power, instead of it going to download mode, it boots up fully then i happen to use it for until when I restart it. I've updated it to Android 5 using some file that i found on some forum, thought it would help but same case. Members, am out of ideas on what i should do. I've flashed it with Z3X box, but i also get an error, same as Odin. Any help is highly appreciated
What are you flashing to the phone? If it was running a stock 4.4.2 ROM or newer, the bootloader would be locked and AT&T never released a complete Odin firmware flash after 4.1.2.

HELP ASAP I was installing my custom recovery and my phone entered a bootloop.

So I was installing twrp and everything went right until it didnt boot to the recovery and from then it keeps booting to lg logo and bootloader warning forever.
I know I can install the stock rom with lg up by I cannot enter download mode since the phone isnt technically turned off. Does anyoene have a solution.
It's my main phone and I literally cannot afford a phone right now.
A way to turn it off would be the solution. Battery was around 70% so it will take a long time to actually have 0%.
Update: I got to the fasboot menu from where I can run fastboot reboot recovery after installing twrp again. Now I have some mounting issues and I cannot flash any zip without entering bootloop. Im trying to use the shut down menu of twrp to try to enter download mode.
2nd Update: solved using lg up with the latest android version.
