Locked BL Recovery not installing. P769 - LG Optimus L9 P760, P765, P768, P769

Hi I have the lg optimus p769 and I tried to unlock the BL to no avail. So I flashed back to stock and updated to 20h. I already got the phone rooted but when I try and install the recovery through the apk it says its installed. But when I reboot to recovery it just passes it and wont let me in. Even if i try to press down when the phone turns on because the led's are not blinking. Any help would be appreciated.

Did you have busybox install? Lock bootloader recovery works only when busybox installed.

You cannot install CM or custom rom on locked bootloader. Please unlock your phone boot loader first. And for recovery problem, did you install busy box? That recovery need busybox installed to work.

Need help..

So, I just flashed my l9 with V20B so I could unlock recovery mode.. I flashed, rooted, installed busy box, then installed recovery apk, did the reboot to recovery, but it doesnt boot into recovery mode, it just goes straight to android.. so what im asking, can someone either help me get my phone up and running correctly? I have the p769 L9.

Phone Stuck Will not boot to system!

Hello guys so I accidentally and idiotically installed the verizon update. Meant to press later accidentally hit now not thinking, and all my phone does now is boot up to twrp. I have it rooted stock rom with G3 tweakbox and twrp recovery. I have tried to wipe, and restore with no luck. Also tried safemode no luck. Phone only boots into recovery and I'm hoping for a quick fix. Also cannot get it into download mode.
Anything help wise would be great kind of in a panic situation now!
Thanks!

did you try flashing a stock based rom?
not a restore.
Have you tried downloading a stock rom (bumped) and flashing that in TWRP?
If you can boot to TWRP you might not be able to resore but you might be able to install a stock rom, the restore apps from a nanadroid if you have it.
Don't worry. Same thing happened to me last week. There are instructions on here that show you how to type a few add line from TWRP and your phone will boot and you won't lose anything on your phone.
Just Google search LG g3 stuck TWRP.

Thanks for the replies. I found the fix thread and flashed the zip and it returned to normal.
Thanks for the help guys.

Lost root after flashing ROM

I rooted my LG G3 with StumpRoot. Everything went fine and I had successful root. Checked it and all. Then I flashed the new Barren ROM (v1) and I lost root. I tried re-running StumpRoot and StumpRoot is claiming I already have my device is already rooted. However, any application that requires root or Superuser, it says that root is not detected. I have Superuser on my phone.
Did you flash through TWRP?
Can you still boot into recovery, and does TWRP come up as your recovery?
This ^^^^^
I have no idea how you can lose root when it's built into it.
Now if you took the OTA update then you will lose root.
Then you have to revert back to zv4 via Flashtool if you want root again.
The FAQ, and the ZV6 threads have all to info you need.

I don't know how I lost root either. I did not do any OTA updates. All I did was "Update Profile" to get my data working again. I've rooted and flashed roms on many phones, never had this issue until the G3.

Did you unlock the bootloader with "Bump", so you have TWRP?
Then just flash the Rom again. Or any Rom for that matter

I downloaded the TWRP listed on some thread on Sprint LG G3 then used flashify on my rooted G3 to flash it, after that I flashed the custom ROM using TWRP.
Since then, I tried to boot into recovery (power+volume down) and it just booted into safe mode.
Also, if/when I do boot it into recovery, should I also try flashing a SuperSU rom too?

The only thing I can think of is that the download was corrupt. I would try flashing TWRP with Flashify again. If that works, then reinstall SuperSU. That should get you root back. Then download a ROM again, verify the MD5, and flash in TWRP.
If Flashify won't run, then try reinstalling SuperSU, and see if that helps. If not, I think you'll have to revert to the stock ZV4 ROM with LG's Flashtool.
I suggest the Barrin V2 ROM. It's the latest version of Barren, built on the ZV6 ROM instead of ZV4: http://forum.xda-developers.com/sprint-lg-g3/development/rom-barrin-odexed-deodexed-t2950747
I tried using flashify and it gave me an error saying I needed root. I tried booting intorecovery husing the instructions and it either just boots up regularly or goes into safe mmode. Have I bricked my phone to this Rom?
Revert to stock as explained here:http://forum.xda-developers.com/spr...de-how-to-restore-sprint-lg-g3-ls990-t2852042
Then reroot, and start over.

LG G5, T-Mobile, trying to install ROM, wont load

Hello everybody!
I have a LG G5 that I unlocked the bootloader, installed TWRP, and im trying to flash the RomAur rom on it, everything seems to install correctly, but when I reboot the device, it goes to the first screen, and wont go any further.
The screen says, "Your device software cant be checked for corruption". With a yellow triangle. The blue notification LED just pulses too. I assume this is from the unlocked bootloader. I followed all the instructions, and am able to flash the 10d FW without a issue. But, for some reason, I cant load any roms? Any help would be greatly appreciated. Thanks

Can you explain the " But, for some reason, I cant load any roms" part? It isn't clear, it can't flash ROMs or Firmwares trough LGUp? It it's the first option then it's normal, flashing a firmware will overwrite the TWRP with the stock recovery.

Hello, and thanks for the reply. I can flash the ROM through TWRP just fine. But, when I reboot the device, it just stays on the boot screen, and pulses the notification light. It wont go any further. Today, I tried to go back to stock by flashing the .kdz file through LGUP, and my G5 isnt recognized. I dowloaded all the drivers, and unistalled, then reinstalled LGUP. Still nothing...
