Cannot boot even into download mode after changing Fast Dormancy setting - G2 Q&A, Help & Troubleshooting

Hi,
I thought I could enter the Hidden Menu and change the Fast Dormancy setting into disabled, so I did it and wanted to reboot my phone. The phone turned off, and was doing its boot up procedure, while it started behaving abnormally. The LG logo popped up for about 5 seconds (so it didn't leave the bootloader), turned off for 10 seconds and then again the whole process repeated. I thought that was a bootloop, so I turned it off, entered Factory Reset menu, chose appropriate options and waited for the reset, but the phone didn't perform the action. Then I tried to get into download mode, but to no avail - the phone kept going with bootloop. I'm still struggling to do this; the only menu I could get into was the Factory Reset one.
Could anyone help me get my phone back into function?
D802, 20G stock
Thanks in advance!

That's weird. I always disable fast dormancy after a reset or a new rom flash and I've never had any issues.
What comes instead of download mode? If nothing, Are you sure you're doing it correctly?
Press and hold the power button for 10-15 seconds.
Plug the phone into the cable, then press and hold volume up and plug the cable into the computer. That should trigger download mode.

Thank you for your help.
I know that's weird, I've entered Download mode numerous times using the combination that you provided and can't do it this time. The strangest thing actually is that the factory reset menu does show up (though it does nothing), while Download mode does not - it seems to be actually unaffected by using the combination and is still stuck in a bootloop. I have no idea what steps should I take in order to recover my phone.
I forgot to mention that the phone wasn't even rooted then, which makes it even more mysterious...

Ouch! Well what comes up when you enter download mode? Fastboot? Black screen?
If you're still covered by warranty take it for a replacement. I doubt fast dormancy alone has messed up your device. If it truly has, then try booting the phone without a sim card.

Normally when I insert the USB cable with vol up button pressed, the LG logo shows up, then the notification of Download mode and finally the Software Update screen. But this time, only the LG logo shows for about 5 seconds, as if I normally booted it using Power button and does not get me into neither Download nor Fastboot mode.
Well, I took a look at other options in this hidden menu, but still, could it brick that hard even then?
I doubt whether I'm still eligible for a replacement, as the device had been rooted already (though it's not at the moment). The whole process also takes quite a lot of time, which is why I wanted to avoid it. Is there any method to bring it back to life?

I wanted to revive my phone using the method linked with flashing the whole partitions onto my phone, but Ubuntu didn't even notice that any drive was connected...
Am I doing something wrong? I mean e.g. is the combo Vol Up + cable still the same in D80220G? Is there any other way of accessing the phone through my computer? Can I somehow stop this bootloop from continuously happening? Doesn't the fact that I can get into Factory Reset menu help in any way?
Thanks for your help in adavnce!

[Q] Download mode boot loop

Hi, I'm hoping someone can advise on a strange issue I have with my phone. If I power down the phone then it powers back up in download mode. If I take out the battery then put it back in, the phone will automatically power up in download mode.
While in download mode, if I hold the power down for 5 seconds to shut down the phone then quickly hold vol down + home + power then the phone loads to the "Warning!! a custom OS can cause critical problems in phone and installed applications" screen. From here, I can press vol down to "Cancel (restart phone)", after which the phone boots normally and everything appears to be fine. All the buttons work perfectly and there doesn't appear to be anything else wrong at all. However, powering down will again cause the phone to go into download mode.
The phone was previously rooted, but while trying to repair the issue I have flashed a stock firmware and tried a factory reset. This doesn't appear to have changed anything though.
In download mode the Binary Status is now Samsung Official and the System Status is Official too (which I'm hoping means I won't be refused a warranty repair). I think the phone may have got a little damp at the Reading festival last weekend, but I find it strange that nothing else appears to be wrong with the device apart from this weird boot loop.
Any suggestions to try something before I take it back to the shop would be appreciated. Thanks in advance for any help or advice.

Can't Enter Download Mode

Hello Everyone,
I've recently come across a LG G2 VS980 that I'm trying to root. However, after constantly trying, I can't seem to enter download mode on the phone. Nearly every website I've been to says to hold volume+ while putting in the usb into the phone. And I managed to get into it once, but now I can't seem to get back into it. Every time I hold the volume+ button and put the usb in, the phone vibrates and restarts again and boots into the phone normally. The phone works perfectly fine. It's not rooted and there isn't a custom recovery. I can enter the Factory Data Reset perfectly fine. And I've done a factory wipe on it three times already. I've tried holding the power and volume+ buttons, I've tried turning on and off developer options, I tried deleting everything off the phone, and nothing seems to work. I've read online to download "(VS980) LG G2 AutoRec-Lollipop APK", however, because my phone is not rooted, doesn't it run the risk of being bricked? I just want to be able to enter download mode which seems to be impossible at this point. If I try anything, the phone simply vibrates and boots regular skipping the download mode altogether. Is there anything I can possibly run to fix this? The phone works perfectly fine and it is not rooted. Also it is running 5.0.2.
Autorec will not work without root. Turn on USB/ADB-Debugging in developer options and try to enter download mode again. Btw the timing while pushing Power+VolUp is extremely tricky. 0.1 second too slow and it won't work. If this doesn't help try one of these tipps: http://forum.xda-developers.com/showpost.php?p=63327417&postcount=4
But none of those will be easy.
Good luck!

BOOLOOP

Hi all, I have been using CM for a long time, but I accidentally deleted the system and data and all the partitions, now I am trying to recover and I am not able to recover. What strikes me is that I try to enter the TWRP mode, I can not, or even Download Mode, nor can I run the adb command (because the phone is off). What happens is that also my power button has problems, when I put the battery, the cell phone turns on automatically, the question that I ask is will it interfere in not booting in recovery and download? Incidentally, when I put the battery at the same time I click on the Home and Volume-, it opens the warning screen on custom Os, but when I press the volume+ button nothing happens besides restarting and flashing in the bootlogo.
Desperately I need your help.
There's not much you can do without download mode. And if the power button is the problem, then I suggest fixing it somehow.

Samsung Galaxy s4 sgh-i337 boot recovery loop

Hello,
I have an S4 from ATT and after it ran out of battery last night it is now booting directly to recovery mode.
When I plug the charger it wont show the battery charging icon, it just makes a short vibration every like 10 seconds and the screen remains black.
I removed the battery and put it back again and tried to press volume down + power button to access the other mode but it wont allow me.
Since It just allows me to access the recovery mode, I performed a wipe data reset and it when through successfully but when phone restarted it took me back to the recovery screen again.
What can I do to fix this?

Boot up into recovery mode and look if it shows errors of any kind. There is a possibility that your phone may have an emmc failure. Its a hardware issue and not software related. There is a small chance it could be as simple as getting a new battery but I doubt it.

Galaxy A40 infinite loop - impossible to turn on

Hi!
I have a problem with a galaxy a40 device, I flashed a stock ROM with Odin, everything went fine, green lights, PASS and all, but now the device just won't go pass the SM logo anymore. When I turn on, logo appears 2-3 secs I get a warning of the unlocked BL then logo comes back and after a second the phone restarts itself and the same goes on forever ( well about several hours, and after that it just shuts off somehow ). I cannot enter recovery mode or download mode at all. I keep pressing the combinations Power + Vol Down, Power + Vol Up, All three and every combinations I have just found on the internet so far. Odin doesnt recognize the phone, which is not a surprise since it won't start up. I have tried with adb but waiting for device is all I get.
How is it even possible that I cannot enter download mode at all? There was no problem with the physical keys, and the power still works, I cannot test the Vol buttons tho.
Has anyone ever had a problem like this? How can I come back from this? Is there a way to flash a ROM without download mode or turned off phone?
Thanks for any help!!
The download mode for this model is different from previous Samsung's :
IIRC, with the phone off, you need to hold VolumeUp and VolumeDown, then plug in the USB cable connected to a computer (you may need to press Power to power up the phone, I can't recall properly).
From there, you should be able to restore a stock ROM with Odin.
Let us know if it helped !

Here the same problem, have a40 in loop and never get rocgnized for computer, tryed many different cables, and installed a booring large amount of drivers software and nothing...
you need to power off device completely. let battery drain if you can't shut down. press and keep holding volume down + plug in usb cable for Odin3 (I doubt both?)

Generic answers, repeated 800 times why really need to waste a post with that? and that not was the problem:
1- For no usb recognition, is this phone bad design, in the back tap where is the battery in the samsung logo more or less if you push with fingers and charge is because the design of baterry is so crap and your usb port goes off when the under tap cable moves or just get little out of conection. If you can get working after push, usb on phone will do too.
