Rest in Peace... or not? - G2 Q&A, Help & Troubleshooting

I have interupted a flash by the 2014 tool. Yes it was my fault but i hope there is something i can do to boot it up or flash it
I get the logo and it just boots up in a black screen. I cant go into recovery or download mode. Any tool that can save this phone?

happened to me once, too... I managed to get into download mode by connecting the phone to my computer, then holding vol up and power simultaniously until the phone restarts (might take a while, maybe 10-20 sec) and then quickly releasing the powerbutton while keeping vol up pressed.
usually there is no way to completely break download mode, so this should work

Cant boot into recovery of fastboot mode

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.

Help! Stuck on black screen and cannot get to fastboot

I tried unrooting my 6T and something went wrong. Now when it boots it shows the bootloader unlocked warning then goes to black screen and stops. It will randomly vibrate when I press the screen or the power button. My computer doesn't recognize it and I can't even seem to be able to turn it off completely. The only thing I can get it to do is reboot by pressing and holding the power and volume up buttons.
Any advice on how I can force it into fastboot or get my computer to recognize it so I can working on it?

Keep pressing simultaneously volume up , volume down and power button all three of them until you get the fastboot screen.
It maybe takes a while...

like the first answer:
hold vol up, vol down and power butten as long as the phone boots into fastboot mode and flash fastboot Rom OR
hold vol up and vol down for about 5-6 seconds, and plug your phone to your computer. if it gets recognized (with typical sound of windows) try msm tool. And be sure you have the qualcomm driver installed.

Looks like soft brick. Try power+vol down, then when phone screen goes off press bixby and vol down and immediately connect the cable, it soud put the phone in download mode.

or he might just have needed to do a factory wipe
Can be, but in that case it should be no problem to enter recovery, but he says that it doesn't go as well

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.
