Help getting phone back from bootloop!! - LG Optimus L3 II, L5 II, L7 II, L9 II

I edited my build.prop file and something must have gone wrong because my phone is stuck in bootloop state now! I've literally tried everything I could find on the internet and NOTHING have worked so far so I hope I could get some Help here.
Heres my problem:
Boot up phone and everything's normal , has boot animations and sound but then it gets stuck on the LG logo animation forever!
I tried flashing the device but got hundreds of errors and never was able to actually flash the device and numerous other solutions and nothings worked sofar.
Another setback for me is that the phone doesn't have a recovery mode ( If there is one pls give me key comb) and I stupidly didn't install CWM before I did this.

Did you try hard reset?

Yes I tried hard reset, no luck. Im gonna try and push the original build.prop file via adb onto my device and see if that works.
But I cant find the file anywhere and I dont have acces to my phone anymore so I cant get my backup from my phone.
So if anyone can get me the original build.prop file for the LG Optimus L5II (E450) that would be great!
Thanks

I would appreciate it if someone could assist me using my phone because all the tutorials and stuff that i've tried so far does either not apply to my situation or not to my device. I have therefore not found a tutorial that has my phone and situation in it. I have not installed CWM or Nandroid backup on my phone so I can't use any solution using any of those. I don't really have any knowledge on ADB so I don't know if you need anything pre-installed on your phone and my phone doesn't have a recovery mode, only a download mode when I connect it to my pc via usb cable. Really any help would be dearly appreciated.
Thanks!

Did you try flashing a stock .kdz from LG?
kdz - http://lg-phone-firmware.com/index.php?id_mod=23
tutorial - http://forum.xda-developers.com/opt...orial-how-to-flash-lg-phone-lg-flash-t2988436

Got phone fixed using the tutorial above! Many thanks for posting this and thanks for all the help!
Really appreciate it and wouldn't have been able to get phone back without the forum!

[Q] [HELP] LG Chat Optimus (LGC550) stuck on LG boot screen

Hi there guys.
Recently i bought a LG Optimus Chat C550 and tried to root it using this method which worked great!
After that i installed a few apps including Rom Manager and tried to install ClockWorkMod Recovery though Rom Manager. It ask me which model my phone was but since it didn't had my model there i chose 1 that said "And others", the phone rebooted after awhile and now its stuck on LG screen.
I've been trying everything but with no luck, my PC doesn't recognize the phone nor ADB.
I'm not a expert just usually follow guides/tutorials. I can't find anything about how to fix it here on the forum or on google :/
Does anyone know how i can get it fixed?!
Thanks in advance

[Q] LG P710 (L7 II) soft bricked

Hi,
after trying to install beats audio my lg p710 has bricked, I performed an hard reset (vol down, power, home) but still it won't go to the setup wizard. I can only turn it off by removing the battery.
I have very little knowledge of android but for what I've understand I need to put the phone in download mode and flash the entire stock firmware.
Can you guys help me? I haven't found guides about this phone since it's quite new.
English is not my first language but I hope it's understandable.
edit: actually it's not "bricked", it's in bootloop

Have you read or search int other section of this forum?? maybe you may try this http://forum.xda-developers.com/showthread.php?t=2284822 but DO WITH YOUR OWN RISK.
I think the method more or less similiar,the different just about the STOCK FIRMWARE,choose for your model here http://lg-phone-firmware.com/index.php?id_mod=21.
Don't forget for driver here http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe.
You can read more in the bottom section from the thread i've said above in the "UNROOTING OR FLASHING STOCK FIRMWARE", don't forget to use firmware for your phone model.
emergency mode=(When phone is off) hold the volume "down" and insert the USB cable (Will Have Yellow Screen)
Hope this will work.
Done! Thanks, problem solved. I flashed the stock firmware and everything now is working again. Good thing that emergency mode still worked.

Somone please help me before I go insane...

Hi everyone!
I ve spend 12 hours trying to set up a custom rom- cynogenmod- on my lg p760 with no success!
After trying everything i could, i m now wondering if its ever possible to successfully boot in recovery mode on Lg P760, or i m absolutly stupid?
Actually after rooting, installing the right busybox, and then installing L9 Recovery installer; i m able to reach the recovery mode, yet still when i attempt to set up, CM from zip, it gives an error at some point and then phone gets destroyed. Which i can only recover with LG Mobile Support tools. I ve been seeing some videos on youtube and know that people can do it and it makes me crazy that i can not!
Maybe the problem is that i just copy the CM-10,1,3-p760.zip file trough windows explorer?
I would be so glad if someone could help me out!
A billion thanks in advance
All the best

[Q] Revive LG optimus L5 II Dual E455

I have an LG optimus L5 II Dual E455. For some reason the operative system failed and the android logo appeared broken when I tried to turn it on. I took it to a shop and they make it worst, now it doesn't go beyond LG logo.
I'm trying to reset the phone to factory setting via download mode, but the LG Mobile Support Tool doesn't help that much, it stuck at 4 or 5% and doesn't go further. I'm trying to flash it but it doesn't work either. I'm using LG Flash Tool 2014. I think the problem might be I'm not using the right .KDZ, I'm not really sure.
Can someone help me? Theres a better way to do it? Needless to say, I don't know a lot about this. Also I've never rooted the phone, not that I know anyway.
HI
Hello starfox3000
Needless to say, we don't have much data on XDA regarding our phone LG E455.
But i have compiled a few things here and there.
Please read the posts by slipsystem, they are quite useful for our phones.
The KDZ for our phone is V10D_00.kdz which is available at:
http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW376985432109876543213/V10D_00.kdz
Its a file of size 516 MB. I found this on the XDA forum only and many thanks to the developer who gave the link(Sorry, I don't remember his name right now). I hope it works.
For complete guide to rooting the phone, please refer alley23 guide:
http://forum.xda-developers.com/showthread.php?t=2343579
Hope your problem is solved soon.
