Sorry, I know nothing about LG phones. You might be better looking for a thread for the ROM you flashed or for your phone's thread. You will probably get better response and help.
Good luck.

Try pressing vol down and then power, so you will get to the recovery.
From there, do all wipes and formats and then reboot.
Theoretically, this could solve your problem.

There, fixed.
th LG update tool is absolutely horrible. I was updating my firmware with this tool and wifi disconnected a few times, (on talktalk, horrible provider) it continued with the firmware download nonetheless, it seems that it does not check properly that the downloaded firmware file is corrupt or not and continues flashing regardless.
Suffice to say, the wifi disconnect happened at around 10% of the download and when the firmware was flashed, it generated the error at around the same time resulting in a phone that looked completely dead. black screen, no lights etc.
Thankfully got it working via the powerup and cable insert and reflashed the recovery from the lg tool.
I wonder how many LG optimus phones get sent back to the company for fixing. I have flashed many phones and devices, never had this type of problem before.
I installed the Supercharged Atrix V5 on my Atrix 2 and it works fine for two days. Than i installed the v5 update 2 and started facing force close issues.
I read the thread and downloaded the second larger file which is said to be restored in case of force close issues. I installed that also but even than faced the force close issues regularly.
So i thought to go back to Stock ROM through Fastboot Files. I tried to restore through RSD Lite but I got an error message saying "Flashing Failed".
And from than onwards whenever I restart my Atrix 2, i got a black screen of AP Fastboot and on top written "Flash Failure".
So every time i have to turn it off and than uses Three Button Method to go to normal powerup and than my phone starts with V5 loaded.
I don't know how to resolve this problem coz even factory resetting or any other method won't work for resetting it back to stock ROM.
Kindly help me out in resolving this flash failure issue.
Thanks in advance....

well do u guys have the right drivers installed? because i got a flash failure. but it was because my dog ate through my cord...
so went to walmart and got a cheap one and needed to install the right drivers. sadly i couldnt cause my phone was dead and i had soft bricked it. so i through it in the toilet and got a new one from best buy insurance! its bull... but whatever.
my advise is see how everything is connected and see if u have the right drivers. then flash the fxz file. also make sure u have the right fxz...
try the restore to stock script that is here somewhere, works wonders for me.
Hi man, I had the same problem but restored my phone without any problem... Can you explain in which step does the RSD lite flash say Flashing failed??? I mean, whenever RSD lite says flashing failed it'll quote the file that failed to flash. So I need you to quote the flashing failed error completely to resolve the issue
I'm using a Mac so I've been doing everything through terminal instead of using RSD. Perhaps I should find a Windows computer somewhere and do a restore from it? My phone works fine, it's just every time I turn it on it opens into fastboot but has the "Flash Failure" message across the top, and no S-off despite my phone being successfully rooted.

Hey guys, I need your help.
My phone was all ok when I slept last night! (I have Purumod v3) I wake up in the morning and the phone was off. when I switched it on,it started bootlooping!(shows only samsung logo)
I tried reflashing it,but the bootlooping seems to persist EVEN when im trying to use the recovery(after the flash when I need to wipe data).If I go to recovery,just when Im about to reach the "wipe all data",it switches off and reboots. I thought its a hardware problem but there is one thing that goes against it ie., the phone does NOT show this behaviour when its in Download mode. when Im in download mode,it doesnt reboot or switch off or anything.
I tried going back to stock(a froyo rom without bootloader) but problem still remains. Tried flashing many different custom roms,still remains the same.
Any idea? Reinstalled Kies drivers and everything. Please help.
Have you tried flashing another kernel or reflashing your current one?
Since the kernel handles boot and recovery while download mode is on a lower level.

Try to find something called "zero fill tar" I think Hillbeast made? its like a deep cleanser, if it is a firmware issue, this should help. flash it then flash any rom over it.
Try flashing this tar file. It's saved my phone many times and here is the file that ava.tar is talking about. For the second file, you have to extract it and you get a .tar file that you flash through odin. :good:
I tried each of the things in your replies. I tried the 0kb file,did nothing,tried the zero fill followed by flashing Kyrillos Rom (froyo) still the same result(bootloop). Also flashed g3mod 2.4.1! this is just so annoying. Thanks so much for your help. I really hope my I could find a way.

Some more suggestions, which are not very likely (not in order of probability of success but in order of quickness), but it doesnt hurt to try
1. Try booting/ entering recivery while charging
2. Try removing sd card (and then sim card as well) then booting
3. Try flashing a stock rom (then try doing a factory reset from stock recovery)
4. If you know somebody with the same phone try using their battery and then booting.
(5. When you lose all hope try the russian/old school methdod, ie. beat it into complying to your wishes )

Hello,
I had a rooted verizon galaxy s3 (CM10) and I recently got stuck in a boot loop. So I connected to Odin and flashed both MD5 files and the root66.tar file, booted into recovery and tried to do a factory reset.
The problem is my power button won't work in recovery mode, so I can not select anything in the menu. The volume buttons work I just cant select anything.
I've searched all over for 2 days now and I can't find anything about my problem, am I screwed or is there something I haven't thought of yet?
Thanks preemptively for the help.
bump please help
Maybe possible to send commands to phone via adb?
Sent from my SCH-I535 using xda app-developers app
Which recovery you are using? Try twrp which recognises touch so no need of power button to select any option. I think class cwm also has touch based recovery.
Thanks doesn't hurt....
Thanks for the replies, I tried to run adb but just runs a lot of code then closes out. I tried to re-download and the same thing happened.
I was using the stock.vzw.root66.tar and BOOTLOADER_I535VRALF2.... I flashed them many times and nothing has changed it still just gets stuck on the 4G LTE screen. Where would I go about finding the recovery files you mentioned? I'm willing to try anything at this point.
Thanks again for the replies.

If it's stuck at the LTE logo, boot into recovery and factory reset.
Edit: to Odin flash CWM or TWRP, you can find both files in Open1your1eyes0's root thread in the dev section. Use either once you're rooted.

If you just want this to be fixed quickly, you could always flash a Full-wipe rom that contains the bootloader, etc. Then after your back in the stock rom you could always re-unlock the bootloader, install custom recovery , re-root and flash whatever rom you wanted.

Thanks for the replies, I've searched the internet for a full-wipe rom and I cannot seem to find one, can you point me in the right direction?
Also sorry for the delayed response, I actually graduated college yesterday.
EDIT: Now I can't get the phone to boot into download mode or recovery mode, the Samsung logo comes up and the screen goes black. I'm pretty sure my phone is ****ed.

Hey guys, I have a little or rather big problem regarding my LG P920. It only boots into CWM, but here the story:
A few days back I updated my phone to the newest version with the official LG Support tool. After this the performance of my phone went downhill. Scrolling, swiping, typing – all those things lagged and lagged.
So I decied to root my phone using this guide: http://forum.xda-developers.com/showthread.php?t=2366916
Everything worked out fine, I uninstalled some annoying system apps but found that the performance didn’t improve all too much. I went to the next step: custom ROM.
I used this guide: http://www.android-hilfe.de/anleitu...s-custom-roms-fuer-anfaenger.html#post5147071
It’s German, so I’ll try to describe what exactly I did.
First I flashed a ported ICS:
1. I Installed the LG Flash tool 1.2
2. I downloaded this ICS (http://d-h.st/QgU : XBSA404_AP.bin and XBSA404_CP.fls) and also the LGP920_110622.dll
3. I uninstalled the LG drivers and installed the CDMA drivers (version 4.9.4) to make sure the phone is listed as ‘LGE CDMA USB Serial Port’ and changed it to port 41
4. I then flashed that ICS (with .bin and .fls), got to 80% and finished
5. The ICS booted with no problem (only problem: it didn’t seem to recognize my German SIM, but whatever)
Then I installed a new bootloader and CWM:
1. I downloaded Omap4boot v1.25a (forum.xda-developers.com/attachment.php?attachmentid=1641950&d=1358098807)
2. And then installed the OMAP4430 drivers through the device manager
3. I downloaded the non-touch CWM v6.0.1.9
4. And then installed CWM using the ‘start_fastboot.bat’ from the omap4boot folder
After this I decided to flash CM 7.2:
1. I downloaded it from the official CM website and put it onto my SD Card
2. I started my phone into CWM using the button combination and made a backup first
3. I wiped data/factory reset and started to flash the .zip from my SD Card
4. At around 60% the progress bar got stuck at ‘Installung Update’ nothing happened for 30mins so I pulled the battery
5. I tried it again and again – no luck
After this is where it all went wrong (at least I think so)
I noticed that CWM gave me this error quite a few times: Can’t mount internal SD Card
I googled it and read somewhere to do a factory reset from the android menu.
So I restored my backup, rebooted into android, went into the menu and selected factory reset.
The phone went through some progress windows and then powered off and rebooted – into CWM.
From this point on I never got it to NOT boot into CWM.
I tried many things:
1. Restore backup again – no luck
2. Flash ROMS again (CM 7.2, 7 nightly, 10 nightly) – no luck (the installation actually finished, but reboots into CWM)
3. Flash stock ROM using the Flash tool (v21.e) – reboot into CWM
4. All kinds of combinations of wiping/formatting data/cache/dalvik/system/batterystats etc in CWM
5. This guide http://forum.xda-developers.com/showthread.php?t=1942836 and the rebooter tool mentioned at the end
6. Using the official LG Support tool to reset upgrade errors – stuck at 4% of installing
I saw another post which suggested to flash universal_recoveryloop_breaker.zip, but this apparently didn’t work and got the phone stuck at LG logo – should I even try it?
I saw other post with similar problems but always another model –p925 or p720 and not much information given about what they did, that’s why I went into detail and hope to find a cure
I saw drastic00's guide here http://forum.xda-developers.com/showthread.php?p=39269819 suggested a lot but wanted to post this first before I try a second guide that might only make things worse.
I spend the last few days in front of my PC and phone but nothing worked – I’m starting to go nuts..
I am willing to try everything, to provide any information you might need to help me figure out how to fix this.
Thank you for any help provided – it is greatly appreciated
If stuck at LG logo try factory hard reset.
Try dreccons recovery loop breaker

But when he wrote that after trying that he didn't even get into recovery anymore I got scared
You said you flashed and it sticks at LG logo. If you are flashing the correct files, not a wrong binary, factory reset should fix that.
Can you enter download mode? i.e. hold vol up, connect usb to pc, insert battery. You should see "S/W". If not you might need xbsall's or Karim Kahale's unbrick guide. If you DO have download mode, you can just flash as in my guide. But I can't stress enough that drivers must be installed to pc correctly.
Ported ics is old and from the Korean device. Could be cmod is not compatible, dunno, but that could be the issue. In that case you may have a 'hard brick.' Wrong ROM with wrong firmware.
Wait so did u flash recovery loop breaker or not? I am confused. If not flash it. It will delete your recovery then you got to flash another but worth it

Sorry for the confusion: I didn't try to flash recovery loop breaker. I just saw another thread in which a guy had a similar problem to mine, someone suggested he should try loop breaker, he did and atferwards his phone got stuck at the LG Logo, that's why I hesitated to try this.

I don't know what exactly I have sorry, this is my first time rooting, flashing and all that.
The phone only boots into recovery. I can flash other ROMs, I can restore backups and do everything else in CWM, but when I reboot I get booted into CWM again.
I was hesitant to try the loop breaker, because I saw the other thread, but I will try it this afternoon and tell you how it went.
Just a quick question: what if I end up stuck at the LG Logo afterwards?
Update:
I flashed the recovery loop breaker and flashed CM7.2.
When I now start the phone the LG Logo appears for a few seconds, then a white screen with small dots/pixels comes up and the phone is stuck there..
sooooo.. i think this is not good.. right?
I started to prepare for drastic's guide, downloaded all the files and will do that tomorrow or the day after, or would you suggest something else I should try first?
I have never installed cmod so I don't know.
You can follow my guide if you want. Like I say, drivers must be installed correctly and you must pay attention to details.
Doing random things is not going to help you.
Why do u want cm 7 anyway? if I would want CM I would go for Cm 10 (my current rom lol) and If i would want GB i would one with 3D support

The loop breaker said to flash a new ROM afterwards, CM7 was the only thing I had at hand, so I tried it.
Right now I don't really care which ROM I flash, I just want to use my phone again :crying:
I'll try your guide if you don't have other suggestions so far, let's hope I don't end up in a recovery loop again - this is driving me mad
I will keep you posted on how it goes with your guide or if I have any questions. Thanks so far !

:confused?: So after you flashed loop breaker what exactly did you do? After flashing loop breaker u need new Recovery not ROM if you reboot and try get into recovery which is not there you gonna end up at lg logo. Is that what you did? Anyway if you do follow drastic00's guide you should be able to revive your phone..TWRP Recovery is integrated in xbsa rom (am I right drastic00? not sure) I would recommend you try xbsa v8 first then you can decide if u want different rom
Also drastic don't want to bring my stuff here but you know what I said about weird startup screen ? He probably got the same thing he said he sees white screen with pixels and dots . Still no clue what could be reason?
Sent from my LG-P920 using xda app-developers app
I have not had this particular problem so I don't know what could be the cause.
Flashing xbsall's v28B rooted ICS should recover the device as long as the phone can enter S/W mode. Yes, it has built in TWRP recovery, but it resides in system partition, not recovery partition. Any old TWRP backups you may have are probably not compatible with this method of custom recovery, so keep that in mind.
You will have a recovery loop when you try to factory reset your device using the soft reset like this
Settings>Backup & reset>factory data reset
Dont do this if you have custom recovery
To do a factory reset use cwm/twrp and choose wipe data/restore to factory setting
---------- Post added at 03:25 PM ---------- Previous post was at 03:18 PM ----------
And to recover on this thing you have to reflash a stock firmware using kdz update or lg flashtool.
I cant provide you links. Im on mobile use. Try to search on forum. Im on mobile use

This is exactly what happened to me. I will try drastic's guide now, it uses stock ROM at one point if I'm not mistaken. I'll keep you posted what happens. Thank you!
It worked! My phone boots normally and everything is fine, yay :victory:
Thanks for all your help, now I just need to explore everything in this custom ROM
Is there a explanation or guide of all the apps in this ROM? I've installed XBSA v8, maybe I'll upgrade to vR3D soon, how much better is it?
Edit: On a second thought...
THIS ROM IS BASED ON CANADIAN ROGERS V30C AND IT HAS NATIVE SUPPORT FOR ENGLISH, FRENCH AND SOME ASIAN LANGUAGES.
IF YOUR LANGUAGE ISN'T ONE OF THEM YOU MIGHT HAVE PROBLEMS WITH SMS NOT BEING DELIVERED CORRECTLY IF IT'S WRITTEN TO ANY OTHER LANGUAGE.
