My rooted sph-l720 will not boot!! Please help!!

I rooted with CF-auto method, phone worked fine. I downloaded CWM Rom Manager and downloaded CWM Recovery through the app. I decided to try and flash TRiforce 5.4 as my first ROM. Selected to back up everything and wipe clean with a full install. Towards the end There was a fatal error. It said it needed to be rebooted. I clicked reboot now. It said something about AROMA installer. Then rebooted. It showed the Galaxy s4 logo, then went black. I waited and waited and waited. And nothing happened. I tried pressing power and nothing would happen. I eventually pulled the battery out and reinserted. Upon pressing power, the same thing. It would show Galaxy s4 logo then go to black. I thought perhaps my battery died during install. Tried plugging in to A/C adapter and the battery logo pops up but the circle that usually continues to flow in a circle just freezes and does not flow. No light turns on to indicate charging. If I unplug the charger it is still frozen on the same charge screen. I popped my battery into a friends s4 and it charges fine, and is still at about 50% power. I've tried vol up+home+power, vol down+home+power and they both get the same results, just the galaxy s4 logo, then black screen. No booting whatsoever. Does this mean my phone is now bricked?:crying:
edit, vol down+ power has just gotten me into download mode! I guess I'll download a stock rom tomorrow and flash it via odin. Sucks because i don't have internet at my house. I'm at the library right now... 15 hours to dl stock rom lol...

Try going into recovery mode again by pressing get down the volume down and home button than finally the power button. The phone should vibrate and then as soon as the Samsung logo comes out let go of the buttons or else the phone will reboot again. Time it right so it goes into recovery

Have you fixed this issue, volume up +home+power is recovery mode, volume down+home+power is to download mode then u press up to complete

Rezzing old thread, I know. But I'm leaving this here in case anyone is poking around for clues to their s4 not powering on.
I have one that does not power on, as in bo combination of "press this and that..." is going to work (as if that isnt the first step in troubleshooting...I know not everyone does it right, but its really annoying when any post mentioning no power on/not responding to any key presses or charger plugin is full of "just try harder to boot it" posts..... Anyways...) The power pins register about half a volt, surging around from 100mV to ~3V . The battery does not charge and there us a constant slowly draining voltage on the power pins while unplugged and no battery.
The only clue Ive found so far us a youtube video of a no power on S4 having its power IC replaced which fixed it. Unfortunately I dont have the tools currently to try it, so at least mine, is still dead in the water.....

[Q] Help please !! Autostart f bootloop "Recovery Booting screen" after flashing Twrp

[Q] Help please !! Autostart f bootloop "Recovery Booting screen" after flashing Twrp
Long time xda lurker here,
I have just thrown my t mobile note 3 into an autostarting bootloop that i dont know how to recover from. I have successfully used this same process 4 times on 4 devices, S 3, tab 2,galaxy light and lg volt. Although this time i used mobile odin as the flash tool.
I flashed twrp to the note 3 because it didnt have any recovery at all. Ive had this phone rooted for about a year without a recovery. After flashing twrp now it constantly autostarts to the logo screen and in top left corner it says recovery booting then it restarts with the same result. Ive tried leaving the battery out for an hour but when i reinsert it, i dont even have to push power and it starts bootlooping again. I cant get in download mode,safe mode, recovery mode, anything mode. Im at a loss. Any advice,any at would be appreciated. Is there any way to fix this.

If the phone turns on by itself when you put the battery in then it's almost certainly the Power switch on the mainboard or the plastic Power button (which is what we interact with).
If that's happening on your phone the first thing to check is the case (if present), to make sure it's not pressing on the Power button.
Next would be to take the phone apart and gently pry the plastic Power button off (there's two legs that hold it in - be careful not to snap them off).
Finally, the Power switch itself - it may just be gunked up, in which case you can try compressed air or electronic contact cleaner (be sure to remove the battery first!) and exercise the switch to get it working.
Otherwise you'll have to replace the switch.

I am going to give that a look right now but it wasnt stuck before flashing twrp. Mobile odin said it was going to restart then it immediately started doing this.
Ok going to check power button now.

The power button seems to be clean on the board and its free on the case, unfortuanately that wasnt the problem.

I've had this before and in my case the Recovery is in place but the boot loop will not let you access it.
Try forcing the phone down by holding down power for >8secs. Then as soon as it goes off, press Vol Up + Home + Power to go to Recovery. If it works, Factory Reset and see if it starts.
If that doesn't work, (Factory) then try flashing a ROM from your extSD if you have one, or flash the TWRP Recovery from there.
If that doesn't work either, remove battery and as you put it back in, have Home + Vol Down + Power pressed as you push battery in - just have battery sitting ready to push in with 1 finger holding it, press the 3 buttons and push battery home. Go into DL mode and Odin a firmware. Get the TWRP .tar file from TeamWiz and flash it from Odin after the ROM. Take the tick out of 'Auto Reboot for both processes. Take phone down, restart in Recovery and flash SuperSU.

Ok journeyman16,
Trying those 1 by 1 right now. Hopefully 1 will work, thanks for reply.

Nothing stops the "recovery booting" bootloop. Although for some reason i now have to actually push the power button before the power comes on after a reinsertion of the battery. But still same bootloop. Idk getting really discouraged with this one.
By the way, I do have an ext SD card with 2 nandroid and a titanium backup but they are useless with what it's doing

That's strange. It might be a timing issue where you aren't doing the DL mode buttons quick enough. DL mode should be available if it gets far enough to try Recovery boot. Did you try having the 3 buttons pressed and holding them down before pushing the battery in? (as in Vol Down + Menu + Power) I ask because it can be awkward to do it all at once - and it takes only a split-second lift of a finger to miss the boot.

Yes i have tried it a hundred times at least, lol. I was holding the buttons then pressing it against my leg to insert the battery fully.
I dont understand it either. Im at the point of just leaving the battery out for about 8 hrs then trying again, basically a hope and a prayer situation.

After my 2 1/2 hrs of sleep i put the battery back n and it went in download mode thankfully.
Tried to start it normally but it just loops to logo without recovery booting on thr screen.
Guess i wiped it somehow with mobile odin. Idk.
Thanks for all the help.
Ill be using regular odin when i get home to restore it.

Note 3 is working better than new
As an update, I ended up putting the tweaked ROM with custom kernal on my device and it just purs along at lightning speed now.That's an absolutely wonderful ROM. I highly recommend it. Only problem is if the battery dies it goes into a bootloop but as soon as I connect the charger it boots up. Not a ROM problem I don't believe though. Oh well thanks for the help guys.

Soft bricked my T280 and so confused!!

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.

Galaxy S7 edge won't turn ON and no charging indications

Hi
My phone was stuck at black screen with blue LED light. I waited for it to drain completely, and then charge it so I can flash new firmware. I enter download mode, flash new firmware and it was a success. It restarts and then stuck again on blue screen with Android robot and some like no signal tv effects on the screen, which I think it crashed. Then I forced restart it using vol down+power and it boots up with blue screen wtih "no command" error. I tried restarting it again and it fully dies on me. It won't turn on again.
Button combinations seem not working, no charging indications.
How can I fix this?
Is it bricked? If so, changing motherboard will fix this?

Try leaving it on charge for a while. The charging light should light up. When you go in recovery, on the "no command" screen, press and hold power button and press the vol. up button. That will take you to the admin / recovery screen.
I didn't know it either and was thinking the recovery is corrupt or not working. It is actually waiting for that command from you (power+vol. up). Once in, you can navigate through the menu using vol. up and down to move and power to select an option.

I manage to get the phone working again and booted up on "No Command" screen again. Holding vol up and power doesn't work. But I manage to do download mode instead, installed new firmware and again, it crashes after Odin successfully pass it.
I attached a photo of the crash.
Btw I think it's charging now but there's no LED light.
-_- Just both this few months ago.
EDIT: also when I restart my phone using vol down, home, and power keys to restart my phone then Vol up+power+home or without home, it skips the factory reset and jumps to "No Command" again. -_-

This is hardware failure.
Go to Samsung service.

Ok I will try that, but can you link me where can I download this pit file? thanks

Update:
I tried to downgrade it, and now I'm stuck installing updates, can't go past it. -_-
oh god, last time Lg G4 gave me headache and now my s7 edge is suffering from abnormalities too. -_-

I had this same problem, I sent the web store that I imported and I am waiting for answers, because it is still under warranty. With each passing day I see more of this problem happening, I find it very worrisome.

Its a hardware issue mate. Had this recently and changed the Mainboard. You should let it replaced if u are in warranty.

UPDATE:
After flashing different kinds of Nougat firmwares nothing happens. Charging light and key lights are dead at this point. Then I flashed some MM firmware, one of these firmware gives life back to the dead LED lights on the notification and keys but phone still can't get pass the blue screen with "erasing" or "installing updates" message. After multiple times of force rebooting it by pressing vol down+power, it booted itself to recovery mode(thanks god!) and I don't know why. Lol. Wipe cached it and factory reset and still brought me back to "erasing" or "installing updates" blue screen. Then finally, after flashing the UK stock MM, all lights came back to life. It's working fine right now and I don't think I'll update it to Android N just yet.

Are you sure you are flashing the correct firmware? Download the latest one and try again.

Honestly it could just be a busted battery instead causing this issue, had this happen before for a client on a s6.
If you already tried flashing SM-G935FD firmware with CSC file which makes the phone automatically do a wipe data / factory reset in recovery mode then you probably have an hardware issue instead.

I think so. After a night powered on (since i couldn't turn it off) i plugged the wall charger and the blue installing system update screen appeared and the phone soon rebooted after ten times like these the blue screen disappeared. How can i check the battery life to decide if it is the responsable? I've measured the absorption of the phone with his stock charger, it is 0.49 ampere does it mean something?
