[Q] how to revive a dead L7 - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

It appears like am in serious trouble. i installed a LED notification APK posted by someone in a separate thread. The installation went normally but when it came to restarting the phone it went grey and wouldn't restart. After i removed the battery to start manually,it didn't come on. its been dead and shows no sign of life. it cant charge and the computer doesn't see it. the button combinations also don't bring up emergency mode. so am seeking for help if anyone can help me.

Thanks for answering but the phone is completely dead and not responding to any of the suggestions made. I am not sure wheather it is me who is not doing it correctly but am now heading to the outlet where i purchased from, as it is still under warranty. I hope they will assist me without unnecessary complications.
as regards to the suggestions given it appears like they work under certain conditions not all and we need to find out what these conditions are.
Edit. What eventually happened is that I took my phone to lg service centre as it was still on warranty.They changed the board .

Problem was solved through service centre. The board was replaced. My imei is now different

If you forsure cant get into download mode ask T-Mobile for a exchange. It is very easy to complete and since it happened after an official update you should have no issues completing the exchange
try pullin battery. plug phone into computer. hold volume up and volume down. put battery in. prest-o change-o you should see an android w/exclamation point in a triangle. if this fails a jig from skorpion(I believe that is his name) might help, just fyi ur vibe is probably 99% un-brickable.
Try to connect ur phone to pc & if you' ve seen an icon phone+pc+!, your in download mode..odin can read it..or you can simultaneously hold vol up + power to get into download mode

[Q] What does this mean?? (picture via link)

My LG L5 doesn't work anymore.
I can update the Firmware using LGMobile Support Tool or the KDZ updater but when i want to power on my device it won't start up.
It shows the LG logo and powers off. I cannot enter Emergency mode only Download mode.
When I plug the telephone in the computer it shows the LG logo, the computer makes the sound that something connects and then my phone shows this: https://plus.google.com/103349772149829538364/posts/ZCZb6QYgaFD
I searched on google for 2 days now but cannot find the solution.
Could anyone help me please?
sorry for my bad English
Search for a v10_downgrade.kdz file on the web, flash it and then flash the firmware that you want

Maybe your phone is discharged completely...

Bricked Phone! - Dead - NEED HELP!!

Hi guys, I'm gonna tell you what happened with my S4 to see if you can help me.
I got a MetroPCS Galaxy S4 (SGH-M919N) then I went to a tech and unlocked it. After 2 days the screen started blinking in pink color and I decided to flash it with a stock ROM from T-Mobile (SGH-M919-TMB-M919UVUAMDL-1366964131) using ODIN. Everything was great, in a couple of days the screen went kinda black (No brightness at all) I could barely see it. In this state with the phone turned off and tried to plug in to the PC or charge it and started blinking in green color. I decided once again to flash it with the stock ROM mentioned above but the phone won't enter in recovery or download mode after that I tried to flash it with the CyanogenMOD Installer......everything was OK but it stuck in about 75%, left the phone connected for 20min aprox and nothing happened. I unplugged it and tried to turn it on (It vibrates but I get no startup sound, logo, boot, anything!) ODIN doesn't recognized anymore, can't enter in recovery or download.
I tried to reboot download with ADB to flash it with ODIN but usb debugging is not enabled and ADB commands doesn't work.
I don't know what to do with my S4, I hope you guys can help me. I'm not in the US so I can't return it for replacement.
I hope to hear from you soon. THANKS IN ADVANCE.

Is the battery working ok? Does the LED go red when charger is plugged in as normal?
What happens when you try to boot to recovery?
If your screen start blinking pink and after that turning black, why do assume it's a software problem? No rom would cause that. It's clearly a hardware failure.

The battery is OK, I tested it already with another phone. The LED doesn't turn on when the charger is plugged in. When I try to enter to recovery it vibrates but nothing else happens (Black Screen).

[Q] L5 - Stuck after Android upgrade

Hi, i'm new and french so I'm sorry for my bad english
I have an Android LG optimus L5 II. I accepted the android upgrade (about 'applications') and now I can't turn on my phone; it's stuck on the 'SRF' logo just after the 'LG' logo. It works but don't start. Please, help me...
Is your phone rooted? And does it have cwm installed?
You may have bricked it but thats not a big deal, the first thing you can trie is to press volume down and the home button, and press power, as soon as your phone vibrates let go of the power button and keep holding volume down and home button. Let go after 10 seconds, your phone shuld factory reset, if it does let it boot. Leave it for 5 minuts on boot. If it wont boot after that, youll need to download kdz to your PC and flash the original OS.
Hope this helped

Thanks a lot for your answer!
Is your phone rooted? And does it have cwm installed?
- Hmm I don't think so(By the way I don't really understand what it means... but i haven't install any custom things or hack)
volume down and the home button, and press power,
- Volume down is the only dead button on my phone, I can't use it anymore...
I tried what i could but it still stuck on the logo....
Uh volume down is a very big problem, you cant go in to recovery or in to download mode to fix your phone.
You can fix all software problems by your self, but all buttons need to finction.
Im sorry to say you may need to go and fix your button befor you can fix your boot problem.

There's a guide for unbrick an LG L5, just google it
Edit: Sorry, I didn't see the "II", my bad. But you can try the same for your model.
Actualy just fornd out to factory reset it you just need hold vol up and vol down at the same time and press and hold power till the phone vibrates, but you still need the vol down button.

Ok, thanks for your answers, my ultimate solution is in unbrick my phone with KDZ, but, according what i saw (maybe i'm in a mistake), i have to get the OFFICIAL rom of my LG E460 from France: I search but I only find dead links....

At step 20, I don't have the "Select country and language" window: it opens the LG update tool but without anything,... I think i've done the previous steps correctly...
Make sure you installed the driver for your phone from lg on to your pc.

Ok, so I connected my bricked LG phone, then I started the 'Automatic Offline Procedure' and set "On" on the Windows Enabler, R&D Test Tool opened, I put the .kdz, click on "Normal Web Upgrade" then "Uprade start".
And the LG Mobile Support opens itself insteed of the LG Flasher, without possibilities: I've already download the drivers on this one: and now I can't see those drivers anymore if I remake this procedure (as you can see on my screen).
I've also downloaded "LGUnitedMobileDriver" for my phone just before that. So I don't think it's a driver problem ...
Where am I wrong?

Try it with one of theas links, befor you use them, re install mobile drivers, btw if you dont see mobile drvers runing or installed in programs see if thay show up when you enable LGmobile modem.
im not sure any of this will work i have the 1 l5 but it worked for me.
