[Q] Installing a stock ROM for my phone - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hello. I have an LG Optimus L7 with a custom ROM but I hate it. I want to go back to the way it was when I originally bought it. I've looked at so many threads on how to revert back to the stock ROM but I can't seem to figure it out. Can anyone help me?

It doesn't work. I keep trying every combination but I can't boot my phone into emergency mode.

[Q] Bricked phone. Can't access ADB, CWM

Hello!
Yesterday I tried flashing AOKP unofficial to my LG Optimus L5 E610, and something went wrong.
When I got the "Update finished" in CWM, I rebooted. I had a good welcome by a white screen, and some random things happening at the bottom of the screen. The phone shows the first LG Logo, but not the second one.
When I connect it to PC, or loader, It stops at just a blank, white screen.
I have tried using KDZ Updater, but it says "PHONE NOT FOUND". The same thing about ADB.
When I try to boot up in the CWM, All I get is a short flash from the key lights, and nothing happening from there.
I have tried entering emergancy, and download mode too, but I am not sure about the key combo for these modes.
Is there a way to get in another working ROM, or the stock one?
Please, help :'(
Edit: I managed to get in to the download mode, but KDZ updater ican still not find my phone when attempting to update

You have to use a special kdz, v10d_download, search it on the net.
And are you waiting holding the buttons until the pone vibrate to enter cwm?

I have the .kdz with the stock firmware. I load it in to the KDZ Updater, and I get PHONE NOT FOUND every time
I have been holding the buttons for about 2-3 minutes, but nothing happend. Not even vibrations, or a single screen flash

You have to flash v10d_downgrade FIRST, and then, when it finisihes, let it boot up (it'll be in russian) , then you can flash anything you want

I managed to get the phone in to the download mode, but it installet JB instead of ICS. Now, I am unable to root the device :'(
Where can I find the downgrade kdz?
Oh, I forgot to mention that after getting it running with JB,it does not want to enter download mode anymore. Ideas?
Ok, so I found the v10d_downgrade.kdz , flashed it, and it is stuck in a bootloop.
Tried flashing the original kdz, but it gives the same result.

Well thats wierd, whats the size of the file?
Code:
253 MB (265.392.128 bytes)
Thats the size of the file that i have. Maybe restart pc & phone and try again.
Actually there is no secure root option for JB (unless you want a chinesse root app)
what did you do to get into download mode

I'd flashed a wrong radio image and the cell now does'nt start just the flashing lights signal, what did you do to enter download mode?
Thanks in advance
Search Google for Hard-Reset followed by your device name. You will get a key combination to hard reset it.
Best of luck!!

Didn't exactly get a fix but I found out how to boot back into the recovery which allowed me to restore a backup. Just hold down the VOLUME DOWN + POWER until you see the LG logo and then hold down the same button combination until you're into recovery.

You need to go back to stock. Try entering download mode and flash kdz. .. Look at the sticky at the top of this forum.

Hi,
To enter in download mode:
Turn off device PRESS VOL UP while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead

Before flashing and getting into rooting your phone and flashing a recovery, I suggest you to read about it.

Boot Certification Verify?

Hi guys, need some help deperately please.
I've got an LG G2 D802 that has received the OTA update to 4.4 and is running fine.
I've since rooted it and i was looking at installing a custom recovery before flashing a new Rom......
I have tried to use Flashify after downloading TWRP recovery through Flashify but after rebooting it comes up with the following in the top left of a black screen;
Error: Boot Certification Verify
810 - secure booting error
860 - cause: boot certification verify
Then the screen goes off, ive left the phone and tried to reboot by just holding down the power button for 10 seconds but on boot i just get the same message then it dissapears and i get a black screen again
Any help or pointers would be great - thanks in advance

Thankyou for the reply - Any chance you could link or give me a quick tutorial on how to do this please?
I've connected the lg g2 up to my pc via usb and held down volume up and power to get into download mode - i get the screen on the lg with 'Firmware Update' on it and a bar with 0% on it and writing that says "DO not unplug the USB connection until the process is complete.
I've located the kdz for my particular device/model and downloaded it on my pc - how do i flash to my phone from here please - simple step by step instructions would be great thanks!
Of course. Please read this thread and if any troubles occure write here
P.S. disable Antivirus before proceeding.

Well ive tried to root again using ioroot 25 like i did initially but my phone doesnt like it at all
I get the little green android with the spinning thing on him but it doesnt go any further than that when i run the Windows Batch File - so going to do the whole process again - frustrating to say the least :/

If you've just flashed the KDZ, do a factory reset instead of just booting to android. (hold volume down + power until you see the lg logo, release for a moment and continue holding the 2 buttons untill the factory reset appears). If you're on the new base with knock on and the ioroot issues the reboot to recovery command it has the same effect, your data is cleared. You have to retry the rooting process (the second time it should work).

I've finally sorted it out now - on the first flash of the kdz my phone pretty much remained the same, it bought it back to life and it wasnt reset at all and i couldnt root it.
On the second flash of the kdz my phone went through the whole set up process again (enter google account, language etc) and i managed to root easily after that.
It's put me off installing a custom recovery now though Ive expereince with the htc one x, dell streak, zte blade ...... all fine but with this im worried about getting a recovery installed incase i mess up again!
I know there is TWRP recovery and Philz recovery available but using flashify was what got me into this mess - do you suggest i use the usb cable and connect to my pc and install a recovery that way?
Side note - ive downloaded TWRP and Phils recoveries but none of them have a Windows Batch File to run hence me using Flashify - ive put the question on both of those threads aswell - where is the BAT command to run?
Thanks for your help
Use autorec m8. First root, second download autorec and click flash. Done
