[Q] No download mode, back to stock? - AT&T LG Optimus G

Is there any way to get my LGOG back to 100% stock (ATT bootloader) without booting in to download mode? My volume down button is not functional in any way whatsoever, so I am unable to get in to download mode manually. I even tried through ADB (assuming I did it correctly -- does anyone know the proper command chain for our device?) and this did not work.
Is there any way to keep them from discovering I have flashed over the bootloader, for warranty replacement purposes?

Nope, that's the only way to get to download mode.

Yeah if you can get into bootloader you could fastboot flash the stock sbl

hi man,did you fix it ?

Not sure if it would help, but have you tried taking the case off and looking at the volume down button? I used to have an old Android whose power button wasn't working until I took the case off and cleaned it out.

[Q] Acer Liquid Mini doesn't turn on

I have a problem with the Acer Liquid Mini, after an update the phone is switched off, and now it doesn't boot! When I try to initialize, the acer logo appears and stays eternally!
Any solution? Has this happened to anyone?
I tried press the "Power on + Camera + Volume down" but does not work, supposed to do hard reset but does not work. Could it be because the battery is less than 40%?
May have to go for warranty
Thanks to whoever can help

You can't come into recovery mode or download mode?
Install Deodexed ROM in recovery or flash stock firmware with Odin.

If you are correctly pressing the combination for recovery (volup+home+power) or download mode (volup+voldown+power) and still not getting into recovery or download modes then I am guessing that you tried Ace GT-S5830 custom ROM (or any other incompatible one) on Ace-i GT-5830i, and your phone is not recognizing the key combinations. In that case, as domnic79 said your phone is bricked, and if USB jig is not working, the only way is to either claim it in warranty or use the JTAG method to unbrick your phone. If you somehow successfully get into download mode; use odin to flash multifirmware stock rom from this thread http://forum.xda-developers.com/showthread.php?t=1822109

Any phone going into Odin mode is salvageable. Just use Odin and flash away. Make sure you do it right. I would recommend you read tutorials and do it step by step. All the best, let us know how it goes.

Maybe the version you used via Odin had a region lock. How about try flashing a rom and then see if you get signal???

Download Mode and bootloader

Hi guys! I've been having problems with my Mega. My phone works really fine. I just got it the other day. But whenever I try to go to download mode or recovery I only get a blank screen but I know that it goes to download or recovery because my phone could detect it. I've been reading some forums that I have to reflash the bootloader of my phone so I could fix that error. Does anyone here confirm this and could anyone provide me a flashabble copy of the bootloader? Thanks!
Here's what I found on the other forums:
makeyourself said:
Your problem sounds similar to this one. I assume when you say 'blank screen' that the screen is powered on?
Power off the phone, hold down VolUp + VolDown + Power for 4 to 5 seconds. Then release ALL AT THE SAME TIME. Now press Volume Up. Now hopefully you will be in download mode even if you can't see that you are. If it doesn't work try it again a couple of times. The reason that you have to press Volume Up is that a warning screen is actually displayed before the phone lets you into download mode.
The phone will give you no other indication that its in download mode and won't 'recognise Odin' when not in download mode. Make sure you have Samsung USB drivers (comes with Samsung Kies) installed on your PC.
Oh yeah and by the way the thread I've linked to suggests you have to reflash the bootloader to fix the 'blank screen' problem.

Could anyone help me out on this one? Thanks
Is this a question with answer? That's a first lol.
Glad you sorted the problem.
This is a question. I need to get the bootloader..
Another question, if I flash the stock rom will it also fix the bootloader? And is it safe to flash with this kind of problem like with the blank screen (but the computer could detect the phone is in the download mode)

If you can get to bootloader and ODIN recognises the device then it is worth a try, can you get to recovery to backup first?
Can't use recovery to backup. I was still using the original recovery not cwm. But i finally flashed a rom on my phone but it still has the blank screen. Atleast I'm not scred anymore that my download manager is not working

Can you boot into the bootloader?
To enter bootloader, hold volume UP and power.
Upon entering the bootloader, you will notice that there is no 'menu' to enter fastboot or recovery. Unfortunately, since the stars didn't align properly, we were unable to tell the new bootloader where to load the images that contain the menu from.
In light of that, you'll have to navigate the menu blind. Use the volume keys to change selection, and the power key to select.
The choices are (in order of pressing volume down):
Start - boot the phone normally [already selected]
Restart Bootloader - reboot into the bootloader
Recovery Mode - enter recovery (CWM)
Power Off - powers the phone off
So, to get to Recovery, you would press volume down twice then power.
Thanks I'll try that out will post results shortly

I tried that nothing comes up even while blind navigating nothing happens tried rebooting into both recovery and bootloader from the power down options and nothing other then this problem the phone works all except both Wi-Fi 4g Data but both were working when I first flashed the ROM

Also when trying to go directly into the bootloader from when the phone is turned off its nothing but a black screen

If you have the android-sdk boot into the rom, and try the command
adb reboot bootloader
or
adb reboot recovery
Ok I'll give that a shot I'll try it out when I get off work.

Was your phone connected to computer while trying to enter download, and does your computer recognize that you have connected to it? Sorry if these sound like obvious questions but trying to rule out what we can.
Yes my phone was connected while trying to go into download mode. And when I plugged my phone into my computer it does recognize it.

I would ask for help in irc maybe ping Shelnutt or autoprime. I was going to suggest running freegee again to see what happens, bit am not sure if that would be risky. Wish I had a better answer.

Phone should not be connected to your computer until your have the program running and the volume buttons pressed. So does your phone say download mode on screen ? You said your computer recognize it, does the program recognize it ?

Nothing comes on the screen when I try to go into download mode just a blank screen like it's off no backlight or anything. The program does show something when the phone is connected but still didn't work.

While the phone is on I turn it off and then while it's completely off I hold both volume keys and press the power button. When I do that nothing comes up not even the boot screen.
