[SOLVED] Some experienced people, please, HELP - G2 Q&A, Help & Troubleshooting

After a few days of struggle, I can't even remember which methods I tried with no luck...
Here's the thing:
1) Stuck at 2% flashing KDZ with flash tool ( can't go back to stock )
2) Entering download mode but cdc serial failed ( I think that's the reason I can't flash KDZ through flash tool )
3) Entering TWRP bumped recovery ( v2.8.6.3. ), but don't work adb sideload/push ( adb devices shows nothing )
4) I'm currently on CLOUDY 3.3 and it runs fine, tried to flash other roms, works fine
Right now, I can't describe how I got stuck in this situation ( with all the methods I tried, all drivers changed )...
Can someone help with this situation?

You cant flash KDZ if you on Cloudy 3.3 or AOSP 5.1.1 (don't know why, don't ask)
I had 2% happen to me too.....probably cant find COM port
Try flashing JB bootloader then a KK rom, then try KDZ

2% error mostly is due to different rom version.
Install LG drivers again and check.
Change PC/Laptop.
Use TOT method.

I had bootloop too but was able to flash KDZ
Enter TWRP using power + vol combo
Shut down phone through TWRP option
Volume up + plug in USB
It should be able to flash KDZ now

[Q] LG G2 wrong rom

Restore a backup made while on an 800 rom or flash a Tom through recovery made for the 800. You could also use an app like rom toolbox to edit the build prop to read D800.

Are you using a D802 stock ROM to flash your phone back?
Where did you get your stock ROM from?

Try to adb sideload a ROM for the D800 (CleanROM is pretty close to stock without all the bloatware).
I have the same problem and have not been able to resolve it. Any update on how your problem was fixed?
HELP!!!!!!!
we have basically the same problem, except i flashed a L01f rom instead of d802. I am stuck in download mode(no recovery or fastboot or adb & will not boot rom). When i try to flash back to stock it says wrong model( i have the d800 and am using the d800 dll & tot file). My device is coming up as an L01f on lg flash tool and download mode.... someone help it is a d800 att.
Try using the .dll found at http://forum.xda-developers.com/attachment.php?attachmentid=2473543&d=1387955530
Just flash your phone like you normally would, except you use the .dll linked above instead. Apparently the DLL linked above is a general LG G2 DLL that works for all models.
Note: When I flashed my phone, LG FlashTool gave me an error at the end of the flash process, but the flash was still successful.

[Q] LG G2(D802) Bricked after Flashing Lollipop(D80230d_00.Kdz)

Hey
I want some info about upgrading to lollipop can cause any damage to Lg g2.?
Can i update LG g2 To lollipop D80230d?
Any issue to update on refurbished LG g2 D802 International version.
Thank you
You need to get into download mode. Keep trying until you get there.. it takes patience sometimes.
Then use TOT method. Sometimes kdz gives these issues.

LG L Bello Lollipop

Hi this is a tutorial to flash Lollipop official firmware to LG L Bello
First you need to download the firmware,
Here is the list of newest firmware to LG L Bello
lg-phone-firmware.com/index.php?id_mod=54
Check most recent firmware
The V10 is the KITKAT version and the V20 is for the Lollipop, then there's a letter, that is little updates, download the one with the "last" letter
The D331, or D335, or D337 is the version of your phone (I own a D331 and right now there isn't a Lollipop firmware for de D331 so I have install one from the D335, and there is no problem, my smartphone works perfectly)
There is no problem installing firmware from other countries, I did it to.
Next download this files:
LG Flash Tool
mega.co.nz/#!CIVgzDKL!WJkGjVpzZQhXb4sd698VXL-DAv6sG0SLAH8QT7H90zQ
Drivers:
mega.co.nz/#!vMlRXJbb!q5DM5rmSxO-oA53yc6B9Vp3CDTZOgLbIAIyjYTTo8zY
1. Install the drivers with your phone connected with your PC, when it finishes disconnect your phone
2. Now turn your phone off, then click continuously on the up volume and connect your phone to your PC, it must be now in download mode
3. Open LG Flash Tool, In Select Type: CDMA ; PhoneMode: CS_Emergency ; Select your download firmware and click in CSE Flash
You can change your language as well
In 10-20 minutes it must be finish and you now have LOLLIPOP

The only difference between D331 to the D335, is that the D335 version is a dual-sim, and the D331 is not, the only thing is that appears that the SIM 2 is not inserted

In my experience I would recommend it, I notice it's a litter faster, the animations run smoothly, the battery before I would get 3hours/3h30 screen on time, now I get 4 hours, and you get the lollipop experience with the LG UI wich I think improve from the KitKat version.

After Few More Hours Of Search I Flashed Some Img file like (Boot.img,laf.img,aboot.img etc) with fastboot then i was able to go to download mode my G2 was on bootloop with lg logo appears and then i think downloaded some wrong kdz file of G2 and flashed it with LG flash tool and now my device is again showing white lines whenever i switched it on or connect to my laptop and after few seconds like about after a minute its Led Light starts changing like before and at the same time my pc recognises it as LGE Android Phone and Cdc Serial communication and after installing Lg Drivers now it its show this in device manager :

Did You try using flashtool, while phone is in this state? Does it recognise it?
What about the LG Mobile Support Tool? I used the tool to restore my 802 after getting security errors and the phone was stuck in download mode.

I am talking about those refurbished sets that come from Ali Baba, Ali Express and Ebay mostly. Their vendors are Chinese, Vietnam, Thailand and Honk Kong.
These sets hardware is a Frankenstein package. And D802 IMEI is injected. On D800 D801 LS980 and their software also tampered to look alike D802.
So LG Mobile Support Tool simply Flashes D802 Lollipop on them and hard bricking them.

LG G3 D855 - No download mode and No recovery mode, only fastboot mode started

Hi everyone,
My LG G3 D855 is not entering into download mode. I also tried to boot into recovery, but fastboot mode starts. The phone is working just fine, but the problem is that it drops signals frequently and 3G/4G is not working as well. Don't know what's the problem. I have tried flashing laf.img, used LG PC Suit to update, but nothing is working. I need some help on that.
Thanks in advance.

Can't go into recovery mode - only factory firmware update mode is working. I think flashing cust.img would solve the problem but I don't know how to that since its booting into recovery and fastboot mode.
