[HELP]Problems after flashing kdz. - G2 Q&A, Help & Troubleshooting

Last day I flashed a KitKat kdz in my g2 to solve random reboot problem.
After flashing kdz,phone started to act strange...a lot of problem occurred...
1.No IMEI(I don't have efs backup)
2.phone doesn't switch off.if I do power off ,then after 5-6 second phone boots up itself.
3.touch screen works complete disaster.tried update touch firmware from hidden menu via otg mouse,doesn't help.
4.unable to do factory reset or data clear..nothing happens after tapping erase everything.Reset via hardware keys doesn't work.
A lot more.now I am posting it finding no help anywhere.
What can I do to bring phone in normal state?
I am using D-802.

Looks like you bought a frankenphone. Which means that you bought a refurbished phone which usually has a d800 or d801 motherboard but has the imei and back cover for a d802

D801 bricked. No download mode.

Short version: phone won't boot, won't go into download mode, won't properly do a factory reset (tries but doesn't do it), need help.
Finally bricked my phone after tampering with it too much.
I was on the stock KK rom released by LG themselves, no root. Reverted back to the 10c firmware, OTA to 10g, rooted and installed TWRP - flashed a Vodaphone Germany KK ROM for the LG G2 because I heard it had minimal bloatware and no bluetooth wakelock unlike the KK version I was on for T-Mobile (my carrier). It had the touchscreen issue which I never experienced before. Tried multiple times to go back to any T-Mobile LG G2 ROM using the LG Mobile Support Tool - no dice. Uninstalled and reinstalled everything twice. So I figured, oh hey, I probably need to use the Vodaphone Germany JB.kdz file, root that, install TWRP, then flash back to the T-Mobile KK version that I had before. Seemed fool proof in theory. Used the LG Tool to do such, it finished smoothly and now my phone won't boot. It won't do a factory reset (it enters the factory reset mode and it attempts to do one but just reboots). It won't enter download mode either. I think I'm screwed here. Any advice?
I found 2 guides, but to even begin to do the first one I need my phone to enter fastboot mode and I can't find out how to do that anywhere.
you say Won't go into download mode? What happens when you try?
It just shows the first screen as it tries to enter download mode, with the blue dots. The screen that comes after that doesn't happen anymore. It used to switch to it after a few seconds and then the LG Mobile Support Tool could connect to the phone, but it can't anymore.

would you PLEASE fix your posts so the signature is at the bottom?
The same thing is happening to my ls980. I'm certain it's hard bricked. Download mode shows on the screen but won't boot into firmware upgrade screen. No recovery at all. Os will not completely boot but does show on pc as LG modem. Think it's totally done for. Let me know if you make any progress because we both have the same problem.

Didn't work for me. Windows and Ubuntu didn't recognize my phone. I actually ended up ****ing up my laptop by overwriting a partition but that's on me.
Decided to take it in to a T-Mobile store and blame it on the Kit Kat OTA. It turns on, doesn't boot, doesn't factory reset, doesn't fully go into download mode - how are they gonna know I ****ed it up? I have basic insurance on my plan because the JUMP program is tied into it. So for a little over $10 a month I just gained access to a warranty exchange of my device which is set to ship overnight. Can't wait. Huge stress reliever. I advise you take your phone into your carrier store and do the same as I did.

So did they fix it for you under warranty?
or they figure out that you root it and play with it !?
because I'm having the same problem with my f320k and I'm thinking to send it back to Korea
Same is the case with me, my phone is dead for more than 20 days.
here are the details if any one can help?

Lg g2 d800 download mode brick without help

Hi friends have tried all the tutorials to get my d800 Lg g2 a brick but none works because my computer does not go into dowload mode gets stuck in the part that says "dowload mode" but did not get off to the screen firmware update.
excuse my English
You need to first download the kdz and lg flash utility with drivers.
Install drivers
The factory reset deleting system, cache, internal sd.
Then shutdown your g2.
Start to downloaded mode connecting your g2
Flash kdz & voila... Done
I too bricked my phone before. My flashing stuck at 49%. Recovered using above method, all is well now
This works 1000%. I bet on it. Just remember to wipe the phone completely before flashing. You will return to stock with unrooted status in download mode. U will have your warranty back too

My download mode does not go to the final screen (Firmware Update but stuck in download mode screen) and also not connect to computer. I cannot change port to 41 as required by LG FlashTool. So how can I do the kdz flash! Thanks.

G2 stuck in recovery and wont enter download mode

So for some reason while working today my phone died and when I went to turn it on it went to TWRP recovery and wouldnt leave it no matter how many times I tried rebooting it. And of course to top it off I cant get it into to download mode to revert to stock and start over. When I hold the volume up and plug it in, again it goes straight to TWRP. Need some help please.
EDIT: In case anyone is having the same problem I had, I fixed it by following this thread: http://forum.xda-developers.com/showthread.php?t=2451696 and had to use the terminal command inside of twrp.
Then it put my phone into a bootloop but I was able to enter download mode then so I followed this thread: http://forum.xda-developers.com/showthread.php?t=2663369 to restore phone to factory. Hope this doenst happen to anyone but in case, there's how I fixed mine!

Did you put cm on it depending on your model lg may have pushed an update to your device with out your permission what is your model number if you took an ota I don't think side loading will help it may make it worse

LG G2 (D802) bricked (bootloop, no recovery) only boot loader

I've flashed a new ROM on my LG G2 (D802) 16 GB and now I'm in big trouble but maybe there's some help in the XDA-Forum?
Here are the facts:
- G2 starts and takes few seconds and then restarts
- Got no CWM Recovery etc.
- Installed the orig D80210A Firmware via Flash Tool
- Can flash anything via LG Mobile Flash Tool
- Can boot into download mode
- CAN NOT ACTIVATE DEVELOPER MODE (nothing happens while ticking on the Build-Number)
- Got NO IMEI (got a EFS Backup via ioroot but without developer Mode I cannot communicate with the G2 via USB-Debugging)
- Facory Reset doesn't change anything
- No network and no GSM (I think cause of the missing IMEI)
Can anybody help?

I've done this 10 times this morning. But I flashed the new kdz file and made the factory reset after flashing. Maybe it will work the other way? Gonna try it tomorrow but don't think this will change anything.
I've got the 49 % thing a few weeks before and the only thing needed was to change the COM Port to 41.
kind regards

What a shame, I'm on the same problem

I think it's BRICKED this time!

Ok, I was on a custom ROM for LS980 and all of a sudden it rebooted and I had no control of anything. There was no service either.
So first thing I did was a reboot. no good. Then I went booted into TWRP and restored my last backup, thought this would surely fix it but nothing. Still booted but had no functionality, plus now it started to go into a boot loop. Tried recovering different versions and no luck.
Then, I decided to use the Flash Tool recovery method. It worked in the sense that there was no longer a boot loop, but I still had no service and could not use a lot of the functions like updating PRL/PROFILE and few of the apps would not launch like the quick remote, it would say "SIM not ready"
I'm pretty much out of ideas at this point as I only have the flash tool option and since I lost recovery.
Is this considered BRICKED or does anyone have an idea? thanks

If you are still able to enter in the ROM it's not Bricked....
Put the phone in Fastboot and flash a recovery via Fastboot commands.
Then you can wipe everything (except internal) and flash a new ROM.
I've never fastbooted before. Is there a quick tutorial link for this?

There is no normal fastboot mode as on other phones. Best thing i think try to go back to stock via kdz/tot method and reinstall root and recovery

So I tried the flash tool again using different TOT files. ZV8 and ZVA files caused boot loops. The only file that almost worked was the ZVC file. By almost I mean, there's no boot loop, and i'm able to use the stock ROM however certain things don't work, like when launching the quick remote app, it says "SIM not ready", or stock video cannot play "Unsupported file type" error, and most importantly I'm not able to get any service.
The good part is, my wifi is working. So next I tried to root, however I get this a "unable to open /system/xbin/su: no such file or directory" (i'm attaching the photo for reference).
Thanks for any other tips of directions.
remove sim card and reinsert try that. Not working.
also check your imei. If its not there you may need to recover it from a twrp backup, (recover the efs that is) at least from the time you had no issues. Not working?
Also I read nothing about wiping. (wipe everything except internal sd) before performing a clean instal. Check for same issues, not there victory.
be carefull with full backups, they might contain the issue you are experiencing.

this is a ls980 so I can't remove the Back cover unless there's a way I don't know.
Also, I lost twrp recovery when I used the flash tool and tot method. Now, i'm trying to root and get recovery back but can't even root.

I am not very familiar with your model. But on the d802 there is a small slot on the side of the phone with a small hole. With the phone in box was a small metal device which you could poke in hole and the slot would open. Maybe other user could confirm.
Did you backup your twrp backup of the phone? Then now is also the time to put it back if the tot method deleted it.
Anyway did you check your imei, (dial *#06#, it should show your imei). usually when service is lost there is something wrong with imei, or simcard.
imei can be recovered by the efs backup in a twrp backup. Simcard via putting out back in, reboot, etc.

Thanks for all your help! sounds like its definitely a imei and Sim related issue.
I don't have any backups but I can get to the factory recovery which has an adb side load option. Do you think I can side load a stock ROM this way? If so, what type of file do I use?
