Unbricking LG Optimus L3 E400

*My apologies, I am a noob, I am new to XDA, I still cannot include the links. Send me a message or comment, I'll give you the links. Sorry.*
Follow the instructions given below:
1. Download LG Optimus L3 E400 USB Driver.
2. Download official LG Optimus L3 E400 stock firmware. It is a .kdz file.
3. Download KDZ Updater and of course, install it.
4. Install LG Optimus L3 E400 USB Driver and restart PC after installation is complete.
After reboting your(restarting) PC...
5. Put your phone into recovery mode.
A yellow screen will appear with "Emergency mode!!" written on it.
6. Now connect your phone to the computer via USB Cable.
7. Run KDZ Updater (KDZ_FW_UPD.exe) as Administrator.
8. Choose the following options in KDZ Updater:
Type: 3GQCT
Phone Mode: DIAG
9. Browse for the .kdz file you've downloaded.
10. Click on "Launch software update."
This process usually takes long time. If nothing goes wrong... try left haha :laugh: just kidding.
If everything goes well, you should see "FINISHED" on the last line on the log screen.
Your phone will automatically reboot (just like what happened on mine). There you go,
your precious phone is back.
If there are more queries regarding this problem, please comment. I'll do everything
I can. I hope I helped. :angel:

Bricked lg l40

Guys, i made a big mistake. I followed a guide to unlock bootloader that was for lg l70 on my lg l40 . Now, i can only boot in fastboot. I cant find a laf.img for my l40 and i dont have the backup. Every time i try to install twrp for l40 (via fastboot flash recovery xx.img) in my phone. I get a crash (purple screen). Is there a fix or should i dump that phone?

LG E460 bootloop, can't open recovery or anything else

So, I've had this problem before, and I know that I managed to get my pc recognise that I plugged in my phone, and updated it with the LG Support Tool but this time nothing seems to be working. If anyone could give me some advice on this problem, I'd be really happy, as I'd really need my phone right now. Thank you in advance.
Download last Europe Open KDZ for your phone from here. Then try start your phone in emergency/download mode and use LG Flash Tool with downloaded KDZ.

That is the problem emergency/download mode doesn't work either. It could be that I'm doing something wrong, but all I get is the bootscreen.
Try this steps to emergency mode:

2. now enter into "download/emergency mode" of your phone... but how??
(i) remove battery then insert battery
(ii) press and hold both vol+ and vol- buttons and connect to computer via data cable. you will see LG logo and '>download mode' on bottom of mobile screen.you will also hear a 'connecting sound' from PC that indicates that your phone is now connected.

If it'll work, continue with LG Flash Tool.

Unfortunately, the software updater always "stops due to an unknown error". If you have a solution for that, I'd be more than happy to read it.

Yes I did. It said download mode on the bottom.
Then make sure you have installed LG Mobile Driver, if not, download and install it from LG site. Also make sure you have downloaded correct KDZ for your phone and have copied it to "LG Flash Tool 2014" folder and use CSE Flash.

Well, I was using an earlier KDZ, maybe that's what was causing the problem. I'll try using this one.
