Hmm. Major Issue Need expert help!

Hi all. I have years of rooting under my belt but this is the first Samsung phone i've owned and I've got quite an issue. I was playing a game and the phone just shut off on me. I went to restart it and nothing. Did a battery pull, i felt it vibrate like it was trying to turn on and still nothing. So I tried to boot into cwm using volume up/down and power and the Samsung splash screen flashes for a split second and then shuts off and the phone just vibrates like it's going to turn on but won't do it.
So I tried battery pulls, holding power down, and now when I plug it into the computer it vibrates every two seconds but won't turn on. What's the deal this seems like a major hardware malfunction and Odin/CWM none of that stuff is usable because it just won't boot into anything.
So last resort do you guys have any suggestions i'm all ears :-(

I've had this a few times before... I forget which one exactly but either vol up + power button...or vol down + power button gets you to download mode and then you can flash the softbrick fix.
or if you do manage to get to CWM, you'll need some quick fingers to get to the "install zip" option before it reboots. once in there you're good to flash your ROM.
or, get a USB jig to get to download mode and flash soft brick fix.

False alarm, apparently there is a battery bug reported on other forums. My phone had read 100% for quite awhile and I was digging the battery life but apparently i was over zealous. The meter was reading 100% but the battery was draining and the phone died. It wouldn't fire up until i left it on the charger for awhile. Very odd, guess I will delete this post and research this battery issue... unless someone else knows more about it

I have the same battery issue, but only when I use my car charger. When I take it off the car charger, it will read 100% till I reboot. Only after reboot will it start reading the battery state correctly. I DO NOT have this issue with the house charger...... Strange.

you guys after charging for 100% go to cwm and format battery status this will probably resolve ur issue.

HELP!!! Battery died yesterday and phone won't turn backon!

Last night I ran my battery down to the point where it said Powering Off or whatever. I charged it all night and nothing. When I plug it in, sometimes it has a red LED in the upper left for a econd or two, then does one vibrate, then becomes completely unresponsive.
I've tried a battery pull and hooking it up that way. Same thing - red LED, one vibrate, then nothing. Some times when it is plugged in, it will show a battery picture with no juice for just a second then it all goes blank again.
I am running AOKP build 4 with Slim Kernel.
HELP!!!!!!!!!

I would try another battery, sounds like the one that you have us showing up as dead even after charging overnight.

Just unplug the phone... pull the battery... put the battery back in and WITHOUT plugging the phone in turn the phone back on (may have to hold the power button for a little while).

Strange plugging in the phone without a battery should bring up the charging screen with a question mark in it I think

So the problem has been remedied, though I would like a little input to better document this problem and solution...
I took the battery out, plugged the phone in, then popped the battery in. Really quickly, I got it to enter the weird screen where it is an exclamation point in a yield sign (I forget what combination of buttons I pushed to get here). It said Volume up to continue or Volume down to do something else. This is where it was fuzzy because I was freaking out about having to buy another phone.
Anyways, I hit the volume button that was supposed to reboot and it went through the boot sequence and showed me charging at 98%. This is strange because it was plugged in all night but non-responsive - not power, no heat, no nothing.
So long story short, if running this ROM/Kernel combo - DO NOT LET THIS THING GO TO 0%!!!
And if anyone can tell me what combo I pressed to enter that screen, it would be very helpful. Thanks guys!

The screen you got to is called Download Mode..
Download Mode - This is a setting in which you will put your phone when using Odin. There are other ways, but most people will reach download mode by powering down, removing the battery, and holding volume down while plugging the factory usb cord into the computer and phone. Odin can only communicate properly with your phone if the phone is in download mode.
For future reference you have to
1. hold volume down + power + home button
2. Per on screen instructions, press volume down to reboot/restart device.
This is a documented problem and one that has been posted about numerous times, glad you figured it out. Also, this will always fix the problem so you should not worry if the phone running this ROM/Kernel combo runs down to 0%.

too bad samsung doesn't have a genius bar.....lol

[Q] Won't turn on, stuck in bootloop?

I have a black 16GB (stock, unrooted), received last Friday. A couple of hours ago it shut down on me while still having ~60% charge. Now when I power on, the Google logo with the black background comes on before shutting down. When I have it plugged in, same Google logo comes up and then keeps restarting to that same point.
I've tried getting into the recovery menu with Power + Vol down, but as soon as I get in, the phone reboots on me. Any ideas...?

When you get to recovery, press and hold power then immediately press volume up. The menu should come up and wipe data.

Sounds like it could be a stuck power button.

Thanks for the suggestions guys, I think it is/was a stuck power button. Couldn't manage to get it to do a wipe, but shook the phone a bit and spammed the power button (methodical, I know) and it seems to be working alright for now.

Spamming the power button is the way I'd do it. lol If it keeps happening though you might have to take it apart and clean it. Here's the ifixit teardown but I hope it doesn't come to that.

s7 is ded jim, no charge, no boot, no DL or recovery

Hey y'all this is my friends phone and he messed up. He was always having battery issues where it wouldn't take a charge and was constantly fighting with it over something. He thinks the phone is cursed. Here's what went down at the end;
Friend was flashing stock firmware to phone. Phone was stuck on one of the flash spots, not sure if BL, AP, CSC, etc as I was not there. Because it didn't appear to do anything and he didn't know to wait it out, he rebooted phone in the middle of flash. Now the phone is completely unresponsive! Plug it in, no response. Hold any buttons, no response. Changed battery, no response.
At my wits end with this phone Anyone have anything or any advice that will help save this phone? Mint condition, would hate to have to write it off.

You sure the battery has enough charge to power on? If you say the battery wouldn't take a charge originally
Holding: Power - Home - Volume Down until the device reboots a 2nd time sometimes gets them back into download mode
A bad ROM flash should not prevent the phone powering up, that sounds more like the original power issue

Holding those buttons does nothing. Even when plugged into USB. I have tried multiple cables. I even installed new battery for s7 and nothing. Screen remains dead and phone has no image or vibration response. It just stopped working after his failed flash.

LG g5 VS987 (Verizon) will not power up or go into recovery mode

Very confused as to what happened to my favorite phone ever.
All was smooth, I fell asleep without charging it which was unusual. Woke up, phone is off & will not power up.
Plugged it up, still nothing.
Fast forward to now, I purchased a new battery (factory) & external wall charger thinking that was the prob b/c there were red dots on the little white battery circles (sorry but no clue what the official name for those are) but still absolutely nothing.
I have no clue what caused the original battery to get damaged/wet. Nothing was spilled, it wasn't dropped.
It's incredibly frustrating.
Now trying all the "push this button, hold that button" recovery tricks that I have combed through and it still will not do a thing whatsoever, zero reaction.
My g5 has officially left the building hasn't it?
So what, if anything, can I try at this point?
I've tried the volume down & power button combo, also tried the volume down wait see logo then press power button...etc...
Willing to try just about anything... I realllly love that rude ass phone!
