sorry was wrong.
try turn phone off, add usb, then press volume up. I think that's it.

Hi
did no work also

I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..

Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142

This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:

Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

first of all - never, but never delete/wipe your internal storage...
second - and i've wrote this many times already:
to turn the device completely off
- your usb cable must be disconnected
- have the device charged for more than 50%
- press pwr button for more than 10 seconds
- at some point, LG logo will show - DO NOT LET THE PWR BUTTON OFF - KEEP IT PRESSED
- only then the device will be powered off completely with the black screen

THANK YOU!! you are awesome.. I misunderstood and i thought that i should wipe everything.. What do it do now?

now you find the thread on how to transfer a rom to a device directly from twrp or adb... or how to flash KDZ stock (then reroot and go from scratch)
i've never done it because i've never messed up anything on my device (my luck) - so i don't know in details - but there are threads on this subjects...
btw one more thing i've noticed in your 1st post - you had an .img rom file
you can't flash .img in twrp - you'll need the rom .zip file...

how do i access TWRP?

search on which button combination to press to enter twrp... (but before you try the key combinations - have the device powered off completely as described above)
on my device and 20h bootloader its
- press and hold pwr button + volume down
- lg logo shows (let the buttons go for a second or less)
- quickly press and hold pwr button + volume up
that works on my device...
you probably have older bootloader (20a) so you can try
- press and hold pwr button + volume down
- lg logo shows (let the buttons go for a second or less)
- quickly press and hold pwr button + volume down again
now - if you have TWRP installed - it will show you a white screen (factory reset) with yes/or no buttons - just answer YES to all and it will boot to TWRP (you answer with volume up/down keys for selection and pwr button to confirm)
if nothing of that works - try searching for other key combos... but afaik those are the only two that exist - depending on bootloader...

[GT-I9515] [BRICK] Help with Samsung Galaxy S4 Value Edition Full Brick

Hi Guys!
I'm new to XDA developers, but I've been following this forum for many years.
I would like to resurrect my old phone, a Samsung Galaxy S4 Value Edition (GT-I9515), witch is most likely bricked.
About one year ago, the device started to randomly reboot, until it no longer powered on (It was NOT rooted or modded).
Recovery also did not work, so I decided to flash the stock firmware with Odin. The flash failed, so i decided to follow a (really stupid ) guide that said that to solve it was necessary to flash a PIT file of the Samsung GT-I9505, so I tried it.
Since then, I'm not able to boot the phone anymore.
What can I do with the phone now? What have I tried? I'll try to be as clear as possible:
Recovery mode:
I can boot into recovery only by pressing VOL UP + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Recovery Mode, 3 different things can happen:
It does not power on
It vibrates, then reboot and freeze in Samsung GT-I9515 logo
It vibrates randomly and then open successfully the stock recovery
Download mode:
I can boot into download only by pressing VOL DOWN + POWER with phone connected to charger, and then inserting battery keeping pressed the buttons, but when I try to boot into Download Mode, it seems that the screen freeze at a certain point while loading the recovery mode warning (this warning loads slowly, like a slide from top to bottom). The device rarely fully load the warning, and when it does, when I press the VOL UP key to confirm entering download mode (sometimes it does not respond to VOL UP click for confirmation and i must reboot) Odin is able to find the device but during a flash the Odin log stop at Setup Connection, so the device is not responding.
Normal boot:
Yesterday, after hundreds of attempts, I was able to start the phone normally (I don't know how) , it asked for the initial configuration and language, but when I turned it off, the problem reappeared and I was not able to boot it normally. In most cases, the device freezes in Samsung GT-I9515 logo, it continues to restart or simply does not vibrate or power on.
When charging, I don't see anything such as the charging battery icon or the LED.
I realize that I was wrong to flash that PIT file, but is there anything I can do to make this device work properly?
Thank you in advance for your cooperation.

Noone?

Boot Looped

Hello! Here is my story:
I had a rooted stock os where i just changed the boot anim and everything was fine. I rebooted my device yesterday , the boot anim was fine etc. until today. When i rebooted my phone today , it booted into download mode with no reason. I didnt do any crap on it and it was fine until today. When i was in download mode i remembered i had a custom rom on my sd card so i wanted to flash twrp. I flashed it without factory reset and it didnt work. Now im stuck in a boot loop and i tried entering recovery but doesnt work.
Ok so i saw you can enter download mode with some key combo but u need the home button which this phone doesnt have (on screen controls).
Is there a way i can go in download mode and flash stock firmware with odin or unbrick the phone?

Enter Download Mode : Turn Power Off. Press and hold Volume Up key + Power Key, When Samsung Logo appears release Power Key only, keep pressing Volume Up key until Android Recovery Mode Appears.

I managed to find this method a long time ago so its fixed. Thanks for responding doe.

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.
