Phone turns on then off - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have the ATT S4.
I used the twrp app to flash a new recovery on my phone. I downloaded the jflteatt and flashed it through the app. Worked all day til the evening that i needed to reboot it. It won't boot up anymore.
I take the battery out, and put it in and then galaxy s4 splash screen comes up. but goes away quickly. I take the battery out again, and put it back in holding volume down, it brings up a screen saying "do you want to install custom OS?" "press volume up for yes, or volume down for no" but quickly the screen goes black again and i can't do anything, even if i try and press for yes.
I take the battery out, and put it back in holding the volume up button. I boots up to the galaxy s4 splash screen with "booting into recovery" in blue letters at the top left part of the screen, then the screen quickly goes black again and i it doesn't do anything.
Is there anything else I can do?
thanks for any help

Any help on this?

Unless you can get it to stay in download mode, no. Does it show a charging battery if you plug it in?

can you get into recovery by holding the volume down button when the phone is off and then powering the phone up while still holding it down?
as long as it turns on and screen comes on, you are not bricked .. it's almost impossible to birck this phone ..
can't get into recovery at all, phone is not responding to anything just constantly stuck on initial white htc screen. have backup on sd though no way to get there through phone
how can pulling the battery not work? If there's no power to power up the screen it should die instantly
Try keeping it out for like 10 mins or more.
Then go to recovery and wipe/reinstall from backup.

And to get to recovery you have to start with the phone turned off (by pulling the battery). Then put in the battery and before you press the powerbutton, press and hold the vol- button down. When you're holding the vol- button, press powerbutton until the screen turns on, keep holding the vol button until you get into the bootloader just in case. From bootloader you can choose recovery with vol+ and vol-, powerbutton to select.
And as long as there's something happening on the screen (e.g. HTC logo) it's not bricked.
cheers Hawks556, all is good now

[Q] Trouble turning on - need help desperately :)

Hi guys. So this is my situation; my phone is currently turned off.
If I hold the power button, the Samsung Galaxy S4 logo appears in with the black background, then disappears and the phone turns off after 1~2 seconds.
If I hold the power, volume down button then I get the custom OS screen. If I then choose to restart from this screen, the phone restarts and the Galaxy Logo shows for around 6-8 seconds then disappears again.
If I go to the custom OS screen again, then press restart, I can then hold the volume up button and the lock button and the blue message saying 'Recovery Booting..' along with the same black Galaxy logo then the screen disappears after 1-2 seconds seemingly turning off, then it vibrates once after a couple more seconds then does nothing again
I can not get the recovery booting screen from simply holding Volume up and the power button, I need to do it after restarting through the custom OS screen.
My phone is also suddenly not recognising the charger being plugged in. There is no observed difference between attempts to turn it on with/without the charger plugged in.
The last time the phone was properly turned on, it switched itself off at around 4-6% battery left and from then on I have this result.
So, can you guys help?
Your power button is probably faulty. Try to wiggle it lose or replace it.

samsung galaxy s7 bricked

My phone wont start anymore it just goes to the att logo and freezes and i also wont go into recovery mode. The model number is SM-G935A.
Switch your Samsung Galaxy S7 or S7 edge completely.
Boot into Galaxy S7 recovery mode by pressing and holding Volume Down, Home and Power keys at the same time.
Release all three buttons when Samsung Galaxy S7 screen flickers and you see a warning sign.
Press Volume Up to continue to the main screen of Recovery mode. Or, press Volume Down if you aren’t sure and want to go back to the normal mode.
You can also try from totally off, press volume up, home, and power.
Last, it sounds as if you recently tried to root?
If that is the case just get into recovery, I know sometimes it can be a pain to get there, and then factory reset in there and you should be back up and running.

It wont boot into recovery mode it just show recovery booting flashing in blue letters then it restarts regularly
If you do not know what you are doing best bet for you is to take it somewhere to get restored. Safest way is to take it to the Samsung reps inside a Bestbuy call ahead and explain the model so they can start downloading the correct firmware.

Completely stuck on "Samsung Galaxy S7 Edge" after root attempt

Hello,
I've recently tried CF auto rooting my S7 edge, as I've rooted all my previous phones. I must of flashed the wrong ROM and am now stuck at the "Samsung Galaxy S7 Edge" screen with the "powered by android" on the bottom. I'm unable to power off the phone, nor go into recovery mode (or any other mode for that matter). When holding down the Volume down + Power + Home button, the phone seems like it 'restarts'. The screen goes black but then it goes right back to the Samsung Galaxy S7 Edge screen. Is there anything I am able to do to restore the phone? Any help would be greatly appreciated.
Thanks
As the phone good black, release the home button, but keep holding the volume down and power. This should place you in download mode.

I've tried every possible button combination, nothing happens. I did manage to solve the issue, I let the phone die then as I plugged the phone into the charger and tried booting into recovery again it worked. No idea what that did, must of been a fluke.

Help on MIXX 700 Black Screen only white light during power on (Bootloop?)

Hi all
I just get the white light and blank screen (no logo, no bootup screen, nothing) on during my tablet boot up. I have tried everything (Power + up button, plug and unplug the power with hold on the up bottom etc) I still can't to get into recovery (factory) mode.
Every time, white light just on and off late. I have also tried to put aside the tablet for few weeks to use up all the battery and restart. Same happen.
Any suggestion I can get in the recovery mode ?
