I tried flashing the bootloader from here.
Then it went crazy or something, and got stuck on the powered by android logo, however i was still able to boot into download mode the first time by holding power + volume down button
to simulate a battery pull then quickly holding the volume down + home + power again. Then I tried flashing TWRP immediately in an attempt to make it work because i have a flash drive to microUSB adapter that allows me to read flash drives from my phone ( so that I can flash the rom properly ). The last time I was in TWRP there was 0 things in my storage everything was wiped after I flashed TWRP the first time
Now im trying to go back into download mode but it just wont let me after the battery pull.
1.) After simulating the battery pull, I immediately let go when the screen is dark.
2.) I immediately attempt to go into download. It shows the powered by android for a second, then flickers then it's back to the powered by android again.
3.) I think my recovery and download is screwed. Or something is going on
=== EDIT ===
I managed to get into download mode and flash back my stock rom.
I think the phone must have read my Power & Volume Down & Home button as the battery pull because I let go of all buttons completely before doing it.
Steps to get out of bricked hell:
• Hold Power & Volume Down until the phone turns off
• Immediately without letting go of the Power & Volume Down button, press the home button as well.
• If the timing is not correct just retry.

Hi,
I flashed TWRP and CM 10.1 but then I got problems with the phone not charging (still having that issue but will post it in another thread). Anyhow I decided to reflash the the stock rom and during the flash the phone randomly restarted. Luckily for me I was able to boot up and everything is working fine. the only problem is i can now longer access my system recovery (power and vol down) or fastboot mode (power and vol up). When trying power and vol down the phone starts up as normal. when trying power and vol up the phone vibrates, the bottom 3 keys light up and then nothing. I have to then hold down the power button to turn the phone off and back on. I hope someone can help me troubleshoot this as I have no idea what to do.
Many Thanks!

Recovery is accessed by volume up, volume down, and power held down simultaneously for approximately 10 seconds or until you see recovery. Not sure about fastboot. Have you tried to see if your in fastboot by using adb and checking for fastboot devices. You may be getting fastboot mode. I forget if it actually said anything on the screen. Good luck!

Ran :good:
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.

Thanks for your help,it sorted out my problem! :good:
I have a Samsung galaxy note 4 with stock android. My phone shut itself off while I was listening to pandora, and when I tried to turn it back on, it got stuck rebooting.
It gets to the Samsung splash screen, and no further. Even when I try to enter recovery mode using volume up + power + home, the splash screen appears with 'RECOVERY BOOTING..." in the corner, but it just reboots again.
I have tried turning the phone off completely using the power button, then turning it on again. I have tried removing the battery, letting it sit, and trying to restart again. I have tried charging it to see if that was the problem, but it's not. If I use volume down + power + home, I can get to the custom OS options, but I have not rooted my phone, so I don't know what the 'continue' options does.
How can I get my phone working again?
Turn off the phone. Enter download mode instead of recovery (volume down + home button + power) and open Odin on your PC and under AP add your .tar file (via Sammobile) and hit OK in order to get stock Touchwiz on your Note 4 again.

hi
firstly ,
If you cannot "factory reset " in recovery ....then and if nothing else works ? and you don't want to take phone to service provider /Samsung service centre .............
last resort is to( but you have to know what you doing !!!!)
is to reflash your device /phone current stock ROM,(that you were on),with Odin /pc..laptop
If you are unsure "how to flash ?" i suggest to Google /search for an straight forward video ,on web /Youtube ?
if so and you can get into download mode ( phone off ,pull battery..... insert battery , volume down + power + home button ) When in download mode ,volume up again and follow normal procedure to flash your stock ROM with Odin
Remember ..that above to flash stock Rom with Odin ,you don't need root.
Also ,in your post above you refer i quote......
"I can get to the custom OS options, but I have not rooted my phone, so I don't know what the 'continue' options does"
i think what you actually mean that you can get into download mode ,???...................
and the volume up is when you" ready " to flash your device and connected to pc/laptop with Odin ...
Also make sure if you know how to reflash ..... that before reflashing with Odin ,you have ticked correct boxes in Odin( .....and how Odin works )
Bottom line ...if nothing else works ,
a reflash of your correct phone ( current stock ) Rom you were on ,should fix it .
good luck
I recently updated my Samsung Galaxy Tab A T280 to the latest firmware and I lost my root. So this afternoon I re-rooted it. Or I attempted to, anyway. Everything seemingly went fine, and I booted into TWRP just fine. I went to flash the ROM and I also selected wipe cache/davlik cache to be done as well, and tapped reboot. My device then turned off and when it started the reboot, it got stuck on the Samsung Galaxy Tab A logo screen and would not move or power off by holding the power button (I tried for a LONG time by using a rubber band to hold it down so I didn't have to, with no luck), and every other combination of buttons wouldn't do a thing, except for holding power + vol down, which made it turn off and back on, but it wouldn't finish rebooting and it just got stuck at the Samsung Galaxy Tab A logo again. So then I thought that maybe plugging it into a charger might not be a bad idea, and after holding down power + vol down again, it turned off and turned on and showed a battery with a charging symbol. I've had it plugged in for an hour and it does not show a charge or do anything except for go back to that boot logo if I unplug it from the charger and again hold down power and volume down separately.
I know it's not hard bricked because it is somewhat responsive so I think there's a chance to fix it, hopefully. I just want it to turn on and fully reboot into anything or in any way that will allow me to be able to fix the issue. My computer will not recognize the device so ADB is not an option right now unless I'm wrong.
Thanks a lot guys, I am so confused and could really use some advice.
What firmware did you install
Try to install original firmware via software "Samsung Smart Switch" on your PC with connected tablet.
I too recommend that you try installing the last firmware that you were on via Odin. Also, when you hit that screen lock issue after a firmware flash, where only the Samsung logo appears do this:
1. press and hold Home + volume up and volume down along with power button (that's all 4 buttons). Hold it there for at least 20 seconds and it should power off.
2. Once the device powers off keep holding the buttons but let go of the volume down button.
3. Once the tablet starts to power back up again release the power button and then in about 1 to 2 second release the rest of the buttons.
This should get you back into recovery. You should at least be able to restore any backup, that you should have already, on your external micro SD.
Good luck.. : )
"Chance Favors the Prepared"
the above post is 100% right. Reboot back into recovery and you'll be good to go. Also twrp has a option to reboot back to recovery so this doesn't happen, just a fyi for future knowledge. Best of luck..
You tried to flash a rom with twrp?
You need to flash stock firmware with odin.
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.
