First Security Error, Now no booting at all - LG Optimus L9 P760, P765, P768, P769

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.

[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.

Help with unbricking my phone!

I was using my phone at work 3 days ago during lunch and it was running fine. I was playing a new Kairosoft game. Once my lunch was over I put the phone in my pocket and I went off to work. When my shift ended I pulled out my phone and it was stuck in a bootloop with the Cyanogen logo. I rebooted it and nothing worked. I went into CWM to re install the ROM and it freezes every time. I used oden to try and fix it to go back and unroot my phone to start fresh. I stepped out of my room to use the restroom and my little curious nephew comes in and grabs my phone in the middle of an update. Now when I turn the phone on it says firmware upgrade encountered an issue. Please select recovery mode in Kies and try again. I downloaded keys and it didn't recognize my phone. I can't even get into clockwork mod recovery anymore. On Odin it has the yellow bar and when I try and flash the files I need to go back to stock it fails when it writes the NAND. I really miss my phone. It has been a while since I have been here. I don't know if my phone is a ICS. I got it last year. I have searched everywhere and nothing seems to work. I'll keep searching because I am determined to get it fixed but I don't want to flash the wrong thing. My phone still goes to Download Mode. According to what I have read it means that it's still salvageable. I hope so. Thanks for the help!
If you can boot into download mode then just flash a rom from there? Problem solved

[Q] Stuck in ATT Rethink Possible Bootloop

Here is the story so far. I rooted my phone and got a little carefree with Titanium back up and uninstalled some essential gapps. I was able to get into download mode and am using LGNPST to restore my device to factory settings. The issue is I keep running into is I am getting stuck at 85%, which I know is a common error point in the LGNPST process. I turn the phone off and power it back on while keeping the phone plugged in and the phone reboots. After a few minutes I finally get an error message saying the following
Process:Upgrade_Masterbin
SubProc: Masterbin Download
Cause: Error: Fail opening port
Any kind of help would be much appreciated
Thanks!
Desconect the phone and do a hard reset.
Alright that seemed to get my farther. After a hard reset I was able to catch a glimpse of the phone setup before the phone immediately shut off. I am going to try and re install stock firmware through LGNPST again to see if this will work finally. Thanks!
Instal the 11c update anf root with the universal root.

[Q] Phone keeps rebooting, unable to enter the recovery

Hello,
I've had my S3 for over a year now and it has been mostly running great. Whenever I've had issues I tried to solve them by myself, but this time I was unable to fix my phone, so I must ask for help.
Here's what happened. I left my phone on my desk today and one of my co-workers fiddled with it. He opened SuperSU and then a message popped up saying that SU binary needs to be updated. He then choose to update it via CWM. The phone then restarted and upon starting shows the startup screen then it tries to enter the recovery, but instead it just shows it for a brief moment and then it restarts again. It keeps doing that over and over again. If I remove the battery and then insert it back again, the phone will turn on by itself and continue to reboot after failing to open CWM.
I tried to enter the recovery, but had no success. The phone did enter the Download Mode though, but flasing a ROM via ODIN will remove all of the data stored on the phone and I really need it. The phone is currently running Android Revolution HD 40.
Is there a way to get my phone operational again without loosing the data stored on it?
Thanks in advance.

did you try reflashing your recovery via Odin?

First of all what are co workers doing messing with your phone I would seriously not be happy!! screen lock comes to mind!
As the above post said flash another recovery in odin I recommend Philz recovery,backup your data in recovery then factory reset if that does not work flash another rom via recovery or return to stock with odin. You can also boot into recovery with adb but I would try above first.
Then charge your co-worker for all the time wasted trying to fix phone
Thank you so much for the idea, I just tried this and it worked! After flashing new recovery via ODIN, I'm now able to access my phone. There was no need to flash the ROM again, as it was fine, the only problem was with the recovery.
And I still have my data!
Thank you very much again, cheers :laugh:

He's actually a good guy and I'm sure he didn't do it on purpose. He told me that he was playing a game and he tried to add more coins using GameCIH. Then the prompt to allow root access to the app came up along with a notification to update the SU binary. He said he pressed that button by mistake. I wasn't mad at the guy, I was only upset that I may lose my data.

Stuck in Download Mode, crashing during recovery

So I was having so many issues with my rooted phone crashing on jasmineRom 7.0 I thought maybe an OTA update had made it through and started downloading. No matter what I was doing the screen would turn blue and then restart. Sometimes it would crash blue again during reboot, and sometimes it would crash and then show the green demigod crash screen. So I researched flashing the .tot files to go back to stock. KDZ I didn't care for because it still showed the phone as modified software, and I wanted full stock so I could use the extended warranty with Verizon if need be. I eventually got the .tot method to work and everything was hunky dory, and showing stock. I upgraded all the way to marshmallow and decided I love every bit of it, but I couldn't figure out how to get my contacts and stuff off titanium backup without root. So I figured, "well roots not the problem if an OTA tried to download it just means I missed a setting or something". So I rooted again. No issues, I reinstalled JasmineRom 9.1 this time. Eventually it started crashing again, although this time I followed absolutely every guide I could find on disabling OTA. So I thought, "Great it's Jasmine" and I really wanted Marshmallow anyway so I followed xdabbeb's guide for getting the 35b bootstack on my phone, worked great no issues, and then I installed xdabbeb's firmware, combined with Edor's debloating zips. Everything was working great! I had no issues, I backed up just my apps, and some data, and reinstalled others and everything was great and working fine, and the phone was still official, no OTA's getting through. That was almost a full week ago. Yesterday I woke up and the phone wouldn't turn on. I took the battery out and put it back in and the phone came on, but then crashed with the blue screen again. So I thought great I guess I'll put it back to stock and use the warranty. By this time though I was having trouble getting it to load past the LG screen. I finally got it into TWRP and was able to wipe everything (except SD card) and then I stuck it in download mode and went to install the .tot files. Weeeeelllll, long story short, it crashed during download mode install with the LG Flash Tool. So now the phone gets stuck in download mode everytime I pull the battery and power it on. And crashes again every time I go to install anything. KDZ doesn't work, the flash tool says it can't communicate with the phone, because it crashes. And LG Flash Tool for the .tot files seems to crash everything it loads the modem, or consistently crashes on LAF:bin_user_mode. So I have no idea. At the moment it just looks like my phone is all funky defective, and Verizon may take it back and give me a new one so I'm going to try that. HOWEVER! If anyone has any ideas on what the issue is or what else can be done, I still want to hear it. Feel free to post
Also I've tried updated drivers for the computer, I've tried rolling back drivers, I've tried different KDZ files, I've tried the LGUP8974.dll fix where you flash that in flash tools and then flash the vs985 dll, which is what I had to do to get it back to stock the first time. I've tried everything I could find online except anything to do with fast boot and shorting the pins. Which I haven't tried because I can still access download mode it just seems to be stuck in download mode. Those methods from what I understand are for hard bricking, and for people who's phones don't turn on at all. Although if Verizon won't help I may try one of the laf recovery methods.
Thanks!
