[Q] Cannot enter Download Mode

So I can easily get into recovery mode, but that is it. I have tried both up and down while holding power. up and down and home while holding power. down/home/power and up/home/power all numerous times and the only thing I can get into is recovery mode. Degugging is on, and odin recognizes phone. Could this have something to do with the tmobile softkeys version instead of the internationals home"button". I also tried the holding up and down volume while odin is running and that didn't work either. I'm guessing i have to install the android sdk and use adb commands. as a last resort unless someone else can tell me what im doing wrong. As I don't own a jig/ dongle. am I the only one who has this problem?

Don't press power at all. Turn the phone off. Now just press both vol+&- and insert your USB cable that is already hooked up to your pc running odin.

Thanks You Very Much I am A f#&!ng retard. That worked perfectly.

yeah you can only go into DL mode when the USB cable is connected to your phone. So it should work when you're connected, phone is off, and then you hold +/- and power.
BUT people find it best to do what killa said

Cant get into download mode,

Im able to get into twrp recovery, and fastboot mode but not download mode... I wanted to put the phone back into stock and i thought wiping out everything would do so but i guess not.
Whenever i press the download mode command which i did was volume up down and power then plug into the laptop the 3 buttons will flash but my laptop won recognized it. I tried installing the LG Optimus G drivers but still unable to install it. Also TWRP says that the phone isnt rooted anymore and has no OS.

First off it's Vol Up + Vol Down while powered off and then plug into computer. DO NOT press the power button.
Secondly what ver. of windows and did the computer have any issues prior with connecting to the phone?
There is another fix but it's a bit drastic and wouldn't recommend it at this point.

oh well that might be the reason why. il try it out..im using windows 7 and it was working before i wiped everything.
link me to that fix if anything thanks

On my phone, Download Mode is only accessed when Vol + and - and power from a powered off state, while any USB cord is plugged in, either to a PC, or a wall charger.

After flashing, i noticed that the phone has some issues powering on and off normally i.e. phone completely died, plug the phone into the charger, screen turns on, phone is theoretically charging, but does not show any charging display icon. Which then forces me to unplug the phone, press and hold the power button for 10 seconds, press and hold the power again to turn the phone on, and immediately plug it into the charger in order to get the phone to normally boot up. I flashed CM 10.2 from the original android dev thread. I think that was just a design flaw that LG had originally, but meh, what can i say.

Skip the reinsert battery part in your item #1:
1) Remove battery
2) Hold Volume plus and minus keys down
3) Insert USB cable while still continuing to hold down those two buttons.
WIthin 1-2 seconds you should have download mode. When download mode appears, then re-insert battery. For sure you're not going into charging mode with no battery to charge. This is the method I always use, and it always works (aside from hard-brick situations, but you can access battery charging mode/graphics, which surely means that ain't you).

not works.

What does your computer say when you plug it in? If in Windows check Device Manager and see what your phone is being recognized as. Can you access the phone's contents via USB cable from your computer? Does ADB recognize it at all? Or does it just loop like that, not starting?
Also, it sometimes takes several tries to get it into download mode, as if you're holding the buttons down and not timed just right, the phone ignore your attempt. Make sure you do not let go of both volume buttons even after you plug in the USB cable, you must continue to hold them down for a couple of seconds (until the DL mode appears). Don't even think about putting the battery back in until you see that download mode box. Try that a few times maybe? If it doesn';t work ,maybe you're boned.

remove battery and place it again. then press both volume+ and Volume - . By keeping pressed both buttons insert your usb cable. don't release pressed buttons until its in download mood. by the way install unified adb driver for android by koush if your using windows 8.1 otherwise lg official driver is ok

Completely unable to boot to download mode

Hi, as the title says I am completely unable to boot to download mode on my E988. I have literally tried every possible combination of button pressing but nothing works. I have tried rebooting to bootloader from cwm but that doesnt work either, all it does is reboot, show the LG logo, then it reboots normally.. I have tried using terminal emulator to use the command "reboot download" but it doesnt work either, all it does is reboot, show the LG logo, then it reboots normally again. It seems that I am completely unable to access it at all. Any ideas?

Have you try with one end of the usb cord already plug in either your computer or phone, hold down both volume buttons, and plug in the other end. This was the only way down load mode would came on for me until I fixed the phone.

Yup I have. No combination of keys and button pressing seems to work for me it's odd.
Sent from my LG-E988 using XDA Free mobile app

To add on to my previous post, when I do the method whereby I hold vol + and vol - and plugging the usb cord in without my phone's battery, a message shows up when it is detected saying that a "...usb device has malfunctioned...". My phone will then just keep showing the lg logo over and over again causing the message to pop up again and again as the phone is detected and then not detected and the cycle just repeats itself. I have tried to reinstall lg drivers but nothing seems to work...
Edit: It would seem that the phone is indeed trying to boot to download mode whether I use the key combination or command, but it is unsuccessful in doing so and just reboots. Has anyone ever encountered this problem?

Can you try to switch to download mode by press&hold VOL+ while inserting the USB cable (connected to PC). Phone needs to be off while doing so.

What happens if you press&hold VOL- (furing the whole procedure) push the power button until the phone vibrates, release the button und press&hold the power button?

Try entering download mode with phone disconnected from USB cable.
Also try to see if it gets recognized by LG-UP or by LG Bridge. These 2 softwares don't need download mode to be able to flash, just the phone to be recognized on some PORT.
Try also factory reset hard menu. Also try switching between Slot A and Slot B. There is also this backup method. Phone is not dead on one of those slots.
If nothing works (but slot a slot b should 100% work) , wait for the firehose, it's just around the corner. That will restore the phone back 100%.
For more info search v50thinq on telegram app. :good:

I can t get to download as it freezes and without the USB cable it doesn't even try and enter. I appreciate the recommendations. I was thinking of the a/b seit hbut without the use of fastboot I am at a loss of how to switch between the two as I thought the system chose and the switch happened upon rebooting once a system had been selected ie as in turning the unit off after loading the os set a flag to go to the opposite system upon completing the inftframs and boot sequence.

So, if the device, as you say, lost power during an update like that, then almost assuredly you have at least one, if not numerous corrupted partitions.
And, it's specific partitions on the device that allow it to enter download mode. One of these most know about or have heard of is the laf partition. But other have to be there also for it to work, I don't remember exactly what the others off the top of my head, but that info is easily found.
The key thing you need (or any others commenting same prob), is to be able to enter EDL mode and have qfil installed and recognizing the device. If you can get that far, it would be easy to find the correct partitions you could flash with qfil and then immediately go from qfil to download mode.
Many many people have done this. Just get qfil set up (see guides section) and get the device recognized. that takes some effort but it's def doable.
