Somone please help me before I go insane... - LG Optimus L9 P760, P765, P768, P769

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] [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] I need help with my p769 because I flashed a rom and it messed up my phone

and i need serious help. I have a LG Optimus L9 LP769 and I tried flashing a new rom but it ended up just booting into recovery but it has a red triangle with an exclamation in it. It was my mistake as I flashed a rom that was for another device. I misread as it was LP790 or 760 or something like that. I haven't been able to boot into cwm recovery since then. I need serious help as its my dad's personal phone and I really need a solution that does not delete any pictures or any personal data. I know, i ****ed up and didn't back up anything.
Also, my computer will not recognize it so i can't do anything through the computer. ADB recognizes it but I can't really make it do anything other than reboot. Fastboot just hangs saying "Waiting for device". I've tried various methods that I've found here on xda but none of them have worked for me.
Please help and thank you

[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.

Help getting phone back from bootloop!!

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.

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!
