Hello All!
I got my LG L9 (P765) brick and need your help. It wasn't unlocked or rooted. Also it has original ROM.
It happened after ordinary phone call. The only thing i saw was "LG" lable. After all common methods i tried hard reset and got dead android on the screen with red triangle. Some hours later i flashed new boot, u-boot and recovery but nothing happens. The KDZ method was done today with no positive results after V10 and V20 instalations (even with hard resets). Custom recovery upload results in "Security Error" on title screen.
So guys please help me. What else can be done to make it load at least recovery? Is it possible to root or unlock such device?
If you have locked bl and device is nonrooted you can service your smartphone in LGe services.
L9 is hard to unlock, but you can go into LG recovery by power volume up and home, smartphone will be connected as recovery. By adb you can writte "adb reboot oem-unlock" to enter fastboot mode and unlock bootloader. If your phone will just restart, try this method few times. After you unlock bootloader you will able to flash custom recovery and chance kernel, install custom rom etc.
i have this same trouble and this is not help...

Hello,
I have a lg p760 L9 V20i-eur-xx which has locked bootloader and I cannot unlock it no matter what I try. Also I made the mistake to try to flash cwm recovery and now I'm stuck at Lg security error. I can still get into sw/upgrade mode but that is far as it goes. I tried so far LG flashtool, no succes, kdz flashing no succes. Smartflash no succes. It seems like nothing works. I was using win 7 x64.
Is there any feaseble way that I can recover my phone and get rid of the LG security error?
Is there any way to unlock the bootloader?
Thank you very much I know most of you are sick of it but please help me ...it's my only phone and I'm lost without it. Thanks in advance.
By the way, how can I check if my bootloader is just locked or encrypted. If it's encrypted then I believe there is no chance of succeding.
Factory reset. Simultaneously press power, menu and volume up or down, the other position bringing up recovery.
I had unlocked the bootloader long ago, but had to re-root a couple if days ago in the process of updating baseband. I could update the rooted rom with LG's service flash tool w/o losing apps and settings, surprisingly, but could not get adb to work with Win8.1 x64. Trying to invoke fastboot menu on the phone earned me the factory reset, now all was gone and still no root and no way to recover anything. No problems with adb on the netbook running Win7 x64, however.
I have an similar issue here. But somehow is triggered suddenly (means I no do nothing specially, at a time I tried to install CWRM, the QuickBoot, and after I assumed that is not clear for me how to unlock bootloader, let it as it is). But starting to Saturday I have random reboots/shutdowns, random LG security error boot screens, I performed an factory reset, and now I am stuck.
Now I am on a "S/W Upgrade" "please wait while upgrading..." from more than a half hour (initiated from LG User Support Tool.
Dear XDA Members,
My P765 now is on Bootloop, it wont load the OS. Before it happened, the phone was fine with CM 10.2 and CWM Custom. I try to flash again an TWRP which can only use to flash CM 11 Unofficial. After i flash the recovery, it went normal. I restarted the phone, and the phone was working. I copy the CM 11 then i try to flash it by entering the recovery again, but the method just open the fastboot page, not the TWRP. and now the phone bootloop on LG logo. I try hard restart, and it couldnt work. i try to flash again the KDZ but the KDZ updater said my phone not recognized. Does anyone knows what should i do to fix my phone? :crying: Thanks before.
BR,
CR
HELP!!
Even my LG-p765 is stuck in boot loop... actulally ringing boot.
But for me it happened during flashing recovery for the 1st time (i used tool tip for doing it).:crying:
Now my phone shows LG logo (just for a second) and restarts. This keeps happening unless i pull out the battery.
Please post, if anyone know how to recover from this the ringing boot.
If you can manage to get into fastboot and flash uboot and xloader, then connect the phone on software upgrade mode, it should connect. Although there is a catch, THIS WILL RELOCK YOUR BOOTLOADER.
No, it won't. If he install kdz by normal usb cable (not 910k), he will still have unlocked bootloader.
So I had a moto e with it's bootloader unlocked, and had a custom ROM running on it; however without my knowledge, someone gave the phone to a local (unauthorized )service center. I am not sure about what they did but after this incident, I get the Bootloader unlocked warning when it powers on, but then it directly goes to the fastboot menu saying that there was a fall through in the normal boot-up procedure, and 'system image validation failed'. However I was able to boot into android by rebooting a number of times. But recently, when it did boot up after several attempts the IMEI numbers were gone, so it wouldn't recognize my SIM cards.
I should also mention that the fastboot menu says that the phone is LOCKED. I tried using fastboot, but i cannot even get the unlock code info, or unlock the bootloader itself.
At this point, what do I do? Do I try flashing the same firmware again?
Thank You.
Try flashing the stock firmware :fingers-crossed: Best of Luck!
Hit Thanks if I Helped!!!!!!!!!!!
So.. a long story.First off, my mother wanted me to change the rom of their Phone a few months ago.I did it.Once again, she asked me to change her rom.a month ago. I wasn't that successful, and ended up resseting it with sp flash tool.And she was back to the factory rom.She asked me once again, she was annoyed because she was with the factory rom, and asked me to change it. But, i cant get to the recovery. After pressing Power + Vol. Up + Vol. Down it stays on the BootLoader.With that being said, i tried flashing TWRP and booting back to recovery via a tool.It didn't boot to the recovery.I did some research on this, and found a diagnosis. My bootloader is locked. Again, did some research on unlocking it, tried with fastboot.I reboot my phone to bootloader with "adb reboot bootloader" firstly then i wrote fastboot oem unlock.On a new line there were three dots. I waited for over an hour nothing was happening. And my phone was only saying "Fastboot Mode."I have the drivers.So is my bootloader locked or what? I just want to change the ROM of the Phone.Can i without Recovery? Thanks! Need help ASAP
I have a LG G Vista VS880 that I rooted with Kingroot. My next step was to nuke the LAF, go into fast boot and use fastboot oem unllock to unlock the bootloader so I could install custom recovery. I got as far as nuking the LAF when I had to stop and fix dinner for the kids. When I got back to the computer I forgot that I hadn't unlocked the bootloader yet and flashed the custom recovery and a magisk patched boot.img using flashify. Now it will not boot into system or recovery. I can get it to boot into fastboot mode by holding the volume up button while plugging it in but all my fastboot commands are locked. I have searched the forums and have found nothing except some info on getting into QHUSB mode by shorting out the test point but that post was for the G3 and when I took off the back plate the configuration was different and I didnt want to mees my phone up any worse than I already had. I just want to get back to stock and start over. Can someone please help or at least point me in the right direction?!?!?!? I would welcome any assistance!
