Nitro stuck on LG Boot - LG Nitro HD

So, my Nitro is stuck on its LG Boot logo. I'm scared to unbrick (even though I've done it before), because I can access CWM, and when I tried installing a new ROM, it just shut down as soon as the process started. The lights blink when turning it on, but thats only for like 1 second before it goes to the LG boot. Should I risk unbricking? I don't wanna have to send my phone to LG again. Plus, my mom would kill me.
EDIT: Managed to get into CWM and flash CM10 again, but now it lags so horrible i'm gonna cry.
EDITEDIT: Restored to CM9 7.17. Works smoothly. Might flash back to CM10 though, I never learn from my mistakes

I know that you may have heard of it before, redownload the rom and copy it to a location of your choice on the sdcard. You can do this with an microsd adapter and than try to flash it again. Just make sure that you wipe everything, that should install everything in default mode.

is this **** bricked??

its just sitting on the freaking LG screen... every time i vol dwn + pwr and double press power it goes normal but then cwm doesn't come up and it just restarts and hangs at LG again. i ****ing hate this phone can someone please help me out? why won't cwm load
can you describe exactly the process you took to port CWM into your phone? Let's see if something happened along the way to cause it to not work properly.
Also, is CWM the one not working, or did you flash a ROM on your phone and something went wrong, and you are trying to get to CWM to restore your phone but not getting anywhere with it?

followed the steps on the cwm thread. used terminal emulator. worked great. was working fine until now. i flashed kernels beta 2 and only wiped cache and dalvik and now nothing is working. no cwm to restore, can't even get to the at&t boot animation. this is a mystery.

Sorry to hear that. Unfortunately I can't help much at all since I haven't done either yet (CWM or Kernels/rom installations) so rather than making things worse for you, I'll leave it to the Pros here to help you. Im sure one of them will respond back soon enough.
Try this:
Disconnect the phone and pull out the battery.
Put battery back in and plug phone to a wall charger. Let it boot to the battery charging screen. Once there press and hold POWER + VOLDOWN
Depends on type of the problem, it helped me 9 out 10 times...
tried it at least 20 times now. just realized that i didn't format /system nor did i update cwm yesterday. probably the root of all these problems. I'm just gonna start fresh with the kdz. I'm on a mac though so its going to be a long night starting with boot camp.
I'm having the same problems...well kind of...
I followed all the instructions for CWM and everything went great. No real issues but had to reinstall the .img twice and then was perfect thereafter. Saw the beta 2 ROM and figured what the hey...downloaded and installed to SD Card. Used CWM/Nandroid to do a backup then installed the zip for the ROM from the sd card.
It took a matter of 10 seconds and said it was successful/done and restarted phone-got a boot loop on LG screen for about 15 minutes and finally did a battery pull-tried several times to get it into CWM with no luck and finally was able to get in-but had to plug it into the wall and wait for charging screen to show. Was able to restore and all was well until turning the phone off.
Turning off the phone now causes the phone to loop on the ATT screen-I can get into download mode and can get into CWM and restore and all is well until turning phone off.
I figured it just needs a fresh install so I've been trying to flash the kdz but the firmware updater keeps faulting and never makes it through the process...so I'm stuck...have all the files I need (I believe) and have everything in place...just can't get it back to normal.
Any ideas from here?
Thanks in advance!
Yeah, sometimes it could be quicker just start over and restore backups...
While you there, would you mind do this: Needed SystemUI.apk from SU640
[EDIT]
@fishscale28:
did you do kdz unbrick before? If not, then perhaps you are not doing it right...btw, kdz file for LU6200 didn't work for me.
Nope-never done a kdz unbrick before-I have the kdz v10i_00 for the 640. I have all the drivers installed, the parser deal installed, windows enabler program running and use the kdz updater to update the firmware. Is there something Im missing here? Seems like several people have gotten the updater to crash when trying to update the firmware...any ideas why?

I went through a few of the threads and saw there was a .dll file to be deleted in the updater folders so I did that and now I can do absolutely nothing with the program. Only start and exit...am unable to select anything, view anything, get anything to function...

I installed from the kdz yesterday and didn't have to delete any files. I'm on Win 7 x64. The first time it ran it told me to restart my phone cause it didn't see it, but the second time it ran until my phone reboot and I killed the program. Be sure you have the KDZ_FW_UPD_EN with UpTestEX_mod2_marwin.exe in it. Hope this helps.
Thanks for your help. I did all that...again...I even deleted, reinstalled all the updater stuff, tried running as admin, tried running in compatibility mode, ran it after deleting the recommended .dll file and the option to do anything was gone, put it back in and was able to run everything fine and a little after extracting the kdz it would crash. I unplugged the phone and re-ran the proggy and it went through the check, noticed the phone wasn't hooked up and finished the check. Plug phone in, start process over and proggy crashes.
I don't get it-I would say its the wrong kdz but its not. I installed all the drivers and it still doesn't work. I've tried every combo of everything and the proggies keep crashing.
Now I was finally able to get into CWM to flash another ROM and was able to get one going-was able to boot into the os but same as before-once the phone is turned off it starts the boot loop. Now its even harder to get back to CWM but a restore works from there. Any ideas on why the boot image keeps reverting back to whatever was screwed up? Has to be something that happens once the system starts up again as it's after a restore and when the phone is turned off. Stumped and would love to be able to use my phone...It seems like flashing the kdz would be the sure fire way to get it done-are there options aside from the updaters that keep crashing?
Thanks in advance!
Maybe http://www.microsoft.com/windows/virtual-pc/ can help?
alright so i got to the 4% thing and my phone rebooted but it kept looping to the screen LG Optimus LTE bootscreen with the pink candy cane. thats it. i did vol dwn + pwr and got the android arrow and box with loading bar no text, then it rebooted back to the optimus lte screen. never got to the setup screen. tried the kdz again and my phone died. now when i plug it in i only get download mode... does it charge in download mode and why did it not get to the setup screen?!

Even after running the kdz, my phone still does that after installing CWM. I don't know if it's something with my ROM or something with CWM, but if you can't get into CWM you probably don't need to run the kdz. I couldn't get into CWM anymore when I ran it.
So you're saying you go into the boot loop after turning off your phone even after unbricking?
I don't get it-now I can't get into recovery and it keeps up with the boot loop. I've tried running on the virtual PC/XP deal and it doesn't crash but now it doesn't even see the phone...reinstalled all the drivers, etc. and still no luck. Is there anyway to get the kdz installed without this updater?

Yes. I don't think that was happening until I put CWM on. But I can live with it until the issue is solved. I don't think I'm the only one having it.

[Q] Stuck on boot logo, no matter what??

Ok, so I flashed a MIUI port for the AT&T Note 2, and it was disgusting...it crashed everything, and needless to say I ended up stuck at the boot logo for a long time. FINALLY managed to get it to flash via Odin...so I flashed Stock Rom...and now it's stuck on Samsung logo...Ok..so I go flash CWM...do a wipe and everything, and install CM10.1 via that...stuck at CM logo. I've left each ROM plugged in, stuck on boot screen for over 20-30 minutes each. I'm at a loss of what to do. Could I need to flash a kernel? or am I missing something obvious? The good news, I guess, is with a few steps, I can get into DL mode and use Odin, and I can flash CWM and get into that..but I can't inject anything into my phone so CWM can use it, I only have what's there now, which is CM10.1. I'm so mad...I've never had too many issues with ROMs but this one jacked things up badly...guess that's what I get for using a port even though it noted that everything was working now. Anyway...does anyone have any advice?
Edit: I flashed CWM, and tried to clear cache/dalvik then factory reset...the first two worked...as soon as I hit factory reset, that's where the screen goes black and it resets...it's like it just refuses to do it. I'm seriously at a loss here. Is it toast?
Edit again: sorry but I'm trying more to give more info. I went into CWM and went to advanced and started formatting one by one...it's when you hit format /data that it immediately dies and restarts. So..something weird is going on there. Can I use a PIT file for this phone, if it exists, to reformat and just get it going? I'm desperate...

Follow directions and Odin back to stock.

Where in the world am I going wrong?

Okay, I don't know what the deal is but I've now screwed my second device lol
I have a T-Mobile H811 on 10H, my second to be exact, and after I follow instructions for low level root and flashing a recovery, everything works fine! For as long as I stay on that rooted stock image...
The moment I flash anything other than the rooted stock image my device looses sound, becomes extremely slow and unresponsive, with the SystemUI crashing constantly and restarting. Shows lock screen, doesn't respond to touch, and if it does it's only for a brief moment before it freezes and then shows "Optimizing Android", rinse, repeat.
This persists through returning to stock with a kdz. Once it begins, it doesn't stop, which is why I had to return my first device...... and it looks like I'll be returning this one as well :crying:
I am no stranger to the game, I was not on 10N, I made sure to use the right COM port (the diag one), I make sure to only flash things for the H811, so what in the world is happening to my device when I flash other roms? My first device I flashed BlissPop nightlies and thought that might have been the reason, this time I just flashed a modified stock image. I for the life of me cannot figure out what I'm doing wrong or how to undo the damage once it's been done.
I still have access to download mode and TWRP
I am desperate for help... I cannot seem to find anyone else who's had this issue. Missing those Nexus 5 days D:
Thanks in advanced
EDIT: I flashed back to stock and took the 10N update (it was like pulling teeth) and everything seems to be working again... but I'd really still like some insight as to what I did wrong lest I do it again.
And now I flashed Bliss and everything is working just fine... strange

G3 (D850) Bricked need help!

I have been having issues with my phone random restarting and sometimes it would go through the app optimization process. So I decided to do a full wipe and install CM13. Everything has been great for the past week but, today it did a random restart and went through the optimization process. However, this time it didn't come out of it but, instead looped back to the boot animation and then optimized again and continued to do this. I tried opening recovery to wipe and reinstall but TWRP gets stuck at the splash screen. I have tried reverting to stock but for some reason the LG Flash Tool gets stuck at "Waiting for Connection". I have tried different computers and USB ports to get the Flash Tool to work but have not had any luck. I'm looking for any help or suggestions that people can give. I am willing to try pretty much anything right now.
Resolved! Used LG Sync to Restore Upgrade and revert to stock.
Try the official LG pc suite.
Once connected, just find something like "restore". The program will automatically rewrite the complete storage chip on your phone.

LG G3 bricked???

Hello everyone
I am writing this post to ask for help. I think I may have bricked my LG G3, and I can't fix it :/
I was trying to wipe everything, to later install a Fulmic ROM (6.6). I wiped everything by mistake after a factory reset, and since, I can't flash any new ROM :/
I am using TWRP 3.1.0, and I can mount the device and the sd card to the computer, and move ROM files onto the SD card. However, when I go to install, and after selecting the ROM (FulmicsROM-6.6Zip), the phone crashes... It runs something and when it reaches the part where it is starting "aroma installer version ...." the loading progress bar freezes and after a few seconds it crashes, rebooting into the LG Logo and stays stuck in there (if I didn't remove the battery I would assume it would stay there for ever, but without removing the battery, it stays in that LG Logo screen without much happening until I run out of patience after several minutes).
I tried install the previous ROM (Fullmics ROM 5.0, which was my previous ROM), but the same thing happens.
Has this happened to anyone? Does anyone has any idea how to fix this? It would be very appreciated if anyone could spare some moments to try and help me sort out this...
Ok, so another update on the situation (but not a good one )
I downloaded another ROM to test (CloudyG3), but unfortunately, the same situation occurs. The phone starts running the ROM after install and soon after that, once it is getting ready to start the AROMA installer, it crashes, and reboots onto the LG Life's Good logo and stays stuck in there
Has this happened ever to anyone? Any idea on how to sort this?
