Messed up after new upgrade - LG Optimus L9 P760, P765, P768, P769

Hey there,
I messed up again! I installed the v20h update using my phone not thinking about anything could break (I don't have a custom rom, I was running stock v20c with root, unlocked boot loader and some minor ui tweaks). Well I thought wrong. I am stuck in clockwork recovery (rebooting also only goes to recovery).
I did two things in an attempt to fix it (which may have been stupid):
- I flashed a CM 10.1 image usin an attempt to just get another android version running
- Using fastboot, I flashed the original LG recovery.img to see If I could revive the phone using the LG software
Now the phone behavior is as follows:
- Regular boot: still allways boots into clockwork (why is that? I thought I had flashed that over with the original LG one?)
- Boot into recovery also boots clockworkmod
- Booting into S/W Upgrade mode works
In S/W Upgrade mode, the LG software seems to recognize things nicely (shows as LGP760, SW Version: V20C).
So next I'm trying to run the upgrade, but it keeps on hanging @55% of first screen ("Analyzing Telephone Settings").
I probably managed to make things worse than needed when flashing CM, so now I thought I better wait on what you guys have to say before doing anything stupid
Thanks in advance!

Fixed this! I used the "fix update mistake" thing of the LG Mobile Support Tool which worked fine (the second time I tried)!

Ok, I turn on phone in s/w mode without battery and run LGMobile Support Tool, next I putt battery and choose actualization. After this phone works fine soo next i restart in fastboot mode and flash clockworkmod recovery.img and finally everything is fine!
thanks a lot for everybody who help me!

[Q] Problem unlocking my phone a second time!

Help Please...I really need some now.
I had my phone unlocked and everything was fine. I have been updating the resurrection remix roms and enjoying them a lot. I was up to ver. 1.7. The problem is that I had some of the screen issues (fine horizontal lines on the screen) and I decided to get the phone repaired. I just got the phone back today and I noticed that Bell repair shop had wiped everything off my phone and put their stock version of ics on and the phone was no longer rooted. I have been trying to root the phone a few times now through Odin (like I did half a year ago) and at first it failed due to not being able to open the serial port. I opened Kies and the phone connected so I knew the drivers were ok. I tried Odin again and this time it went through and gave me a pass......but on reboot, it just hangs on the Samsung screen and I cannot turn the phone on at all now. I either am stuck on this screen or the CWM screen, but it won't carry out any command ie. power off, open zip from scard etc. I really need some help and quite worried about the phone now.
Please, please help
you allowed usb debugging?, go back to download mode and flash a kernel with root.
Go to download mode and flash a stock kernel. If you are unable to get into download mode because you said that your phone wont accept any commands for example pressing buttons then you could buy an USB jig. This will bring you directly to download mode. That would propably be your last chance.
Then flash a stock kernel back on there. Maybe the exact same which was on there before. Or just flash a stock full ICS Rom.

Yahoo!! I finally got the thing unstuck. I tried the Odin procedure again but this time I downloaded a more updated root kernel. It passed, then on bootup it wasn't stuck in space......although it still did not boot up properly. It ended up going just black...with no screen whatsoever. But the CMW program was working though and I was able to do a system restore from a month ago. I was very happy and very lucky I made that backup. Now, not only do I make the Titanium backup, but I also do a backup from the CMW program.....because now I know it's possible to freeze up before I ever get a chance to use Titanium. A good lesson indeed.

[Q] ill pay money for help. brick

LG C800
Device will not enter fastboot.
Can't get into recovery mode.
Each time it boots it hard resets. There is an unofficial CWM Recovery Rom on this forum from chui101 which is for this exact phone, but I have as of yet not had any luck in getting the phone to take it.
So far i've tried Flash_image recovery.img (renamed chui's CWM recovery file to recovery.img)
Doesn't seem to matter what I do the phone starts(LG on screen), resets (the LG goes away for a sec then comes back), does a hard reset (a white box with an arrow pointing out of it an to a little android), again resets the phone one last time for a "normal" boot.
I've tried a few different things to try and flash anything overtop of the stock recovery but nothing works. It seems like very early in the bootstrap is a command to do a hard reset and anything that gets put in AFTER that command is ignored. (And the phone hard resets and anything else it was supposed to do is gone.)
Device is rooted with SuperSU.
Phone is fully functional except that it hard resets every boot, and if its plugged in when off it doesn't go to a charging screen, it starts the phone 100% up.
Adb devices CAN see the phone.
I CAN get into Download (sometimes called Emergency) mode.
"reboot recovery" doesn't do anything but reboot the phone as described above.
I can't afford a new phone guys, so I'm over a barrel at this point.
i'll pay whoever provides meaningful help in getting this thing fixed.
You should start fresh. So, flash the stock rom FTF of your phone, then the phone should boot up normally. Then you could either root it and install a CUSTOM recovery, or flash a pre-rooted custom kernel that already contains a recovery. From there, just flash the custom rom you want
Just press thanks if I helped, no need for money
stock rom FTF?
From the factory?
I'd love to do that. But am bewildered as to how when every guide I've found says use fastboot -- which doesn't work on my device. And every guide without fastboot thus far has not worked. I've been reading 10 hrs a day for the last 3 days looking for a solution to this.
If there was a way to completely wipe the entire phone and then install stock rom I'd be glad to do it.... I have found no such guide... only those to replace recovery. (not a 100% clearing as if it came right off the line with no software yet installed)
Additional information:
mv /system/recovery-from-boot.p /system/recovery-from-boot.p-bak
Spits out a "No such file or directory" error
I don't know about you, but for Xperia Devices there is a PC software called Flashtool to flash stock roms and custom kernels and stuff from the PC. There should also be a software like that for your device. You just download the stock FTF for your phone (just type in google "download stock FTF for LG C800") and flash it in Flashmode that should be working
One more thing, this issue is not called bricked
press thanks if i helped
There is an LG tool but it says current software is up to date.
Other option is run recovery, which just reboots the phone as is.
No, this software I am talking about is not made by LG or Sony in my case. It should be a general tool for all LG devices. it should root, flash, install busybox, etc......

LG MOBILE SUPPORT TOOL ?
Thats the one that so far doesn't work.
the one named:
KDZ_FW_UPD_EN ?
He doesn't appear to support GSM phones. Plus I hit "Read info from phone" button... it gets almost everything -- correctly -- then crashes.
IT wants kdz files... looking for them now... chui has a dl link for the stock recovery but even though its a few mb it looks like only a zipped folder hierarchy with no files.
Slightly mis-read. still not finding any "generic" flashing software
trying octopus now....
crashed....
run as admin..... ah... you need their hardware which is hundreds of dollars...
Flash image gui, phone is not supported.
ok, a couple cyanogen dev's have both told me i'm screwed. Imma try for the rest of today and then just never turn it off again.
ok, paying lg to fix it... anybody guess what that will cost?
Try flashing CyanogenMod on your phone as no stock firmware is avaiable currently for your phone cyanogenmod shall fix the problem and you should boot normally (first flash CWM)

First to put the cyanogenmod rom in the sdcard use adb push - http://forum.xda-developers.com/showthread.php?t=1667929

Probably will fix the problem....
hi techmasta,
I'd love to flash cyanogenmod, but the phone never enters fastboot to flash anything. The first link you posted says to use fastboot. I can't do that. The phone doesn't goto fastboot, it runs its recovery first.
EDIT: if there is a way to force it while the phone is in download mode that could probably work.
secondly, I've spend more than 40 hours on this issue, mostly reading forums but still a great deal on google.
I'm pretty unhappy with google as neither of those droidnoob forums ever come up. And believe me, there isn't much out there referring to the lg c800 so they should have!

[Q] Need help with returning to stock LG Rom.

Hello.
Few days ago I decided to try out CM on my P760, this was the first time ever I did this and it was a lot of stress of gathering needed info and fear of bricking it
Before I had it updated to 4.1.2. I successfully rooted it and unlocked bootloader and installed CWM Recovery.
Then I installed CM 10.1.3 stable and everything looked smooth and nice.
Though after playing around with it I decided to return to previous LG Rom.
Reasons:
1) Everything looks darker, very noticeable difference in contrast from stock rom. Need to run in background and play around with Screen Adjuster for workaround.
2) Battery drained noticeably faster than stock.
3) No player was able to play .avi files as smoothly as stock player.
But I made a huge mistake on stress, I did not back up rom, somehow I missed this step.
So, I thought this http://forum.xda-developers.com/showthread.php?t=2085344 guide would help me out, but I am stuck on step where I should enter software upgrade mode.
According to this:
Post-JB issue: If you have installed JellyBean before, Phone may not go in "Software Upgrade Mode" or Flashing stops at 14%
Then do this WORKAROUND: Keep the Phone POWERED ON with USB connected and on "LG Software" mode and do next step of flashing KDZ with Update tool and the phone will automatically go in software upgrade mode.

I need to set "LG Software" on phone, but I have CM installed and it doesn't have such option. If I go in this mode by holding volume up button and connecting via usb, phone freezes on message "S/W Upgrade Please wait while upgrading", and tiny mesage in corner "Bootloader Status: Unlocked". And also this is what LG support tool shows: http://i.imgur.com/g2bbt1P.png.
So, I would like to ask for some help here. If there is nothing I can do about, maybe I can stay with CM, if someone could help me with issues I listed. :angel:

First Security Error, Now no booting at all

I flashed cwm via nandroid manager, got the security error and i have been trying to fix the issue since. Unfortunately, Now my phone will only go into S/W Upgrade mode. The problem is i have tried flashing the x&u boot for ICS to reflash back to normal but the phone auto exits S/W mode at 15% or 8%. Have tried with JB x&u boot, doesnt read phone for install. The version of android im running is 20h. Have tried online mode, wont restore at all.... Have flashed a stock recovery through fastboot to no avail. Phone isnt even charging now.... HELP! Please.
Update:
For some reason, the phone wants to all of a sudden work. I will NOT turn the phone off. Thanks for the guides all of you that have taken the time to make them. I dont remember all of you but thank you for your hard work and dedication to trying to make us happy. Keep up the level of awesomeness.

How can I flash to CWM externally? I've softbricked my phone!

Hey lovely ladies and gents,
So here is the situation: I have an LG Optimus l70 MS323, which until yesterday was with a stock ROM. I banged my head against the wall, trying desperately to follow a guide and root it, along with trying to unlock the bootloader until I watched a video (in Spanish. Thank you high school spanish!) which used flashify to flash a CWM and boot to the custom recovery. I loved it, since that meant that I would be able to finally flash an official Cyanogenmod OS. The first ROM that I flashed was cm-13.0-20160121-NIGHTLY-w5.zip, which worked and made me feel SO HAPPY (I almost yelled Eurika for the sake of historical comedy). I then went ahead and installed an Superuser-SU binary update through the CWM recovery because I wanted to keep on having root. Then I installed a nano gapps package for ARM, Android 6.0 with some minor complications (mostly the "Setup Wizard" crashing every 2 seconds). I rewiped and reinstalled Cyanogenmod through CWM, flashed gapps on the same go, and made a little backup through the recovery menu. I booted up successfully to be met with that buttery-smooth GUI of Marshmallow (ugh, so good.) I decided to go ahead and fetch some apps from the Play Store, such as Messenger and ROM manager. I saw that the Cyanogenmod Update Center had pushed out a notification that the newest nightly snapshot is already downloaded and decided "Meh. What new features have been added? Let's reboot and reinstall." At that point it was 4:40am (keep in mind that I've been trying to get the goddamn phone to cooperate since ~10pm) and I noticed that the boot sequence takes up a lot longer and told myself "It's probably taking a bit longer than usual, it's normal." I put the phone next to my head, hoping that it's going to be ready to use in the morning.
Fast forward to 8:07 am. Bootloader is still going, phone is so hot it can cook an egg.
GNAAAAAAAAAAAAAAAAAAAHHHH. WHY YOU GOTTA DO DIS TO ME PHONE?!??! WHY!?!
SO, the CURRENT situation:
1. Whenever I press the power button, it starts off normally. According to my definition of bootloop, it's stuck in a bootloop.
After hours of staring that goddamn cyanogenmod mascot do you realize that it's going to boot itself into the booting oblivion.
2. I don't have access to CWM. I have tried holding down the power buttons with godknowswhat combinations (I like to call them the Naruto Jutsu of pure despair). Maybe I should hold the buttons for 2 milliseconds longer and it might work. *Sigh*
3. I don't think that I can use fastbood or adb. My computer doesn't see the phone. (GNAAHHAHASDJFLSKDHFSLJHLKJ.)
4. I am totally clueless about what I should do or try. I've basically softbricked my phone and don't know how to unbrick it.
So, now that you see that saying that I'm frustrated is truly an understatement, what do you suggest I do?
In advance, I'd like to thank you SO MUCH for even giving a sh!t about my problem.
Other misc info: I have a 32GB SD card on which I have all the different tools I have used throughout this journey.
I am willing to have it back on stock ROM. My biggest goal is to somehow boot into CWM recovery. From there on, I will be able to deal with it. Until I come back to this forum, begging for mercy.
Have u tried using LG suite or LGUP u need to go to LG 's firmware page I'm not sure about this phone but it worked w my k7 about 100 times also helped unlock it. Check out the LG k7 forum lots of guys on there that use the lgup program and can help
