MY Galaxy Tab 7.7 I815 is not working, please help! - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

I use my Galaxy Tab as a navigation in my car, last night i was watching a movie and i did not charge it, it was 8% left battery life,
This morning i mounted it in my car, put the GPS on, tried to charge it with my car charger, it kept notifying me every 5 seconds the tablet is charging, and not charging, (keeps connecting and disconnecting) till it gave me a black screen, since i was driving i ignored it.
when i reached my destination, i was able to put in download mode, by hitting volume down and power, then i hit volume down to restart. then it gave me a black screen again, tried to do the same thing then i hit volume up to get me in download mode, then i powered it off somehow, i do not remember, now i am stuck in black screen,
had it on the OEM charger for an hour, it does not seem to be charging, i am not able to get in download or recovery mode.
i have had this tablet for 3 weeks now, never flashed a custom rom or rooted it,
is there any way to put it back to life? please please help!

Why are you trying to go to download mode, simply plug to an AC power outlet, leave it for seconds & keep pressing the power button for around 3-4 seconds, it should boot up normally.

Thanks for responding, i have been plugging my tablet to a power outlet for 3 hours and it's not showing it's spring any charging animation, it looks like soft bricked, even tho i didn't flash any roms, very weird!

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.

[Q] Blackscreen, cant access my tablet at all

Hello, good morning.
I was using my tablet normally and left it on the desk for to cook lunch and came back finding it blacked out and doesn't respond to anything I do. Doesn't power off, nor power on, no sound, no nothing. Just the tablet as if it's closed. And no it's charged, I tried to put it on the charger as well, but nothing.
It's booted, and it's a GT-N8000.
Note: I'm a new android user.
Did the tablet recently take fall/ beating?
Try pressing the power button for about 15 seconds and seeing if it will power down so u can reboot it

This happened to me once i freaked out.. There is a tread about this somewhere.. If your having the same issue. A app (i do not remember what one) Locked up the device while the screen was off. So i opened it disconnected the battery .
Reconnected the battery put it on the charger and hold the power button 30 seconds and it Booted right up.This was on the original firmware .You can leave it unplugged until the battery is depleted totally and should give you the same results.Well its if the same issue of course..
It didn't fall or break or anything, I didn't even install any new apps lately.
I tried to hold power button forever but nothing, as if its turned off(well its possibly turned off).
How do I take out the battery what so ever?

One rare possiblity is that the battery is dead.
Use the original charger and cable and keep it connected to charging for at least 1-2 hrs and then try to turn it back on.
If the battery is fully discharged its not always possible to charge with a generic charger or generic cable.

[Q] nexus 5 red light

hi guys,
2 days ago I got a nexus 5 loved it until today I was playing a game (asphalt 8) and it just turned it self off don't know why just did now all im getting is a flashing red light I was on holiday with the phone could the plane have done something to it anyway guys please help me
thanks
Prime
No, the plane didn't do anything to the phone.
Did the battery die? Did you stick the phone on a charger after it turned off?
Best guess is that it's overheated to the thermal shutdown limit.
Leave it a while then try powering it back on

na, when you hit the safety shutdown temp, all it does is shut down, you can boot it right after. ive reached it many times(on purpose), it works.
what the op is describing sounds like the rlod on the nexus 4(red light of death). it happens when the phone thinks it went below 0%. on the n4 there are two solutions, one works sometimes, the other all the time. the one that works sometimes is leave it on the charger for several hours, then try to boot into the bootloader, then shut off the phone from there and keep charging. the method that works 100% is to remove the back cover, disconnect the battery, then reconnect it. this is a hard reset for the battery, and works 100% of the time on the nexus 4.

You may want to give this procedure a try, its copied directly from Google's product support page for the Nexus 7.
Make sure there isn’t any dust or lint in the power port.
Using the original power adapter and USB cable, plug your Nexus 7 into a functioning power outlet. Nexus 7 has specific power requirements, and the USB cable and power adapter that are included are designed to meet those requirements.
Ensure the power cord is securely connected to the tablet and the power adapter.
After 1 minute, check to see if a battery icon appears on the screen.
If the battery icon appears, press & hold the Power button for 15 to 30 seconds to see if the device turns on.
If the battery icon doesn't appear, try accessing the Android bootloader menu:
Press & hold the Volume down button. While holding Volume down, press & hold the Power button for at least 10 seconds until you see an Android robot and the word Start on the screen.
Press the Volume down button until Power off is highlighted. Press the Power button to select that option.
Disconnect the charger and reconnect it within 10 seconds. A battery icon should appear on your screen.
Once the battery icon appears on the screen, allow your tablet to charge for at least 1 hour before turning it back on.

I got a new one thanks for all your help
I just had a red blinking light and no charge indicator situation, as well. Nothing seemed to work: plugged it in for 20 minutes, unplugged it for 20 minutes, plugged it back in...and after another hour on the charger I finally noticed the blinking red light had gone away, and hitting power brought up the charging indicator as normal. Booted right up and has been fine since.
My Nexus 5 just started doing this. I was in the middle of playing a game while my phone was on the charger (Brave Frontier) and suddenly the screen went dead and I had the red flashing light. I'm guessing I was using the juice faster than the charger could fill it so I killed it. I couldn't get the battery indicator to come back but as I was typing this the red light finally stopped flashing and the phone rebooted.
This happened to my N5 today. I was on a Hangouts video chat while plugged in from wall charger and I noticed the battery was actually draining rather than charging. So I figured hangouts was discharging the battery faster than the charging. Eventually it went to 0% and stayed that way for a while and suddenly the screen went off and the LED started blinking red. Followed the steps posted here, plugged in, left for a while and the blinking stops and phone boots up.
Never Hangout-ing with low charge ever! D:

My phone won't boot.

Okay this is my story. First i installed Purekat ROM wich didn't work so i had to combine it together with Katik for missing apps. Then it worked great for a week. When i was out i left my phone on a table, it was on 35% battery. 10 minutes later i checked my phone and it was dead, i tried to turn it on and it did, but it showed that battery was low on 0% it shut down. When i got home i tried to turn it on but it didn't work, when i plug it in a charger nothing happens, i try to turn it on while it's on a charger and it just vibrates, sometimes when i turn it on a charger it just flashes white. Can anyone help me here?

Can your phone boot to recovery/download mode by pressing power button+volume up/down button?

Phone crashed and won't turn back on

I have a stock phone HTC One (M8) that has never been rooted. Today I pulled my phone out of my pocket and it wouldn't turn on. I've tried:
pressing the power button along with the volume up
Pressing power and volume down
Pressing power and volume up and down
I took it to the Verizon store and they said they would have to ship a refurb out to me. I wanted to check this forum to see if anyone has ideas before I get a refurb.
Thanks in advance!
Simular situation - will not power up or hold charge
Im S-off and unlocked .... I downloaded the new RUU 4.4.4 and everything was fine. the next day the battery drained completely and I plugged the charging cord in. I got the battery icon in the center of the screen and 0% life. The orange light is blinking, but the battery level doesn't change. I cannot get it to power up or get into the bootloader. Once I unplug the power cable the unit doesn't power on. if the keep the unit plugged In for a power source I'm still unable to boot. I'm totally out off ideas ... can I get someone to respond to help me out in this desperate time.

Can you try a different charger and cable? The blinking orange light is what they do when they are completely dead. Starts out blinking and wont go solid until enough charge is present to actually boot the phone.
I just upgraded to 4.4.4 as well maybe 3-4 days ago. I had been able to charge the phone a couple of times without issue right up until it wouldn't turn on yesterday.
I left the phone off the charger overnight and tried rebooting again this morning, and nothing.

Same here .. Been on the charging cord for a few days without any change in battery %.
Dodat ... Is there anyway to revive the M8 to accept the charge?

Try this:
Battery is fully charged, but the device does not turn on
Plug device into the provided HTC wall charger that came with the device.
Press and hold the Power, Volume up and Volume down keys for 1 - 2 full minutes. The battery should re-calibrate and the device will then turn on.
or
Battery shows less than 0% charge level
Plug device into the provided HTC wall charger that came with the device.
Charge the device until the LED indicator glows solid red.
Attempt to power the device on as usual. If it will not power on, press and hold the Power and Volume up keys for 10 seconds while still on the charger.
I tried this just now, nothing.
When I hook up the charger, I don't get any lights to indicate that the phone is charging.
It's like the phone is bricked, but I haven't messed with any ROMs at all. I'm completely stock and locked.

I am unlocked but am having the same problem. I've had the phone since almost launch day and it's been fine until now.....all of a sudden it won't charge. I've tried many different cables and chargers that I know work, but nothing gives.
Were you able to figure anything out? Really don't want to have to get a refurb as I don't think I'll be able to get it rooted/unlocked anymore.
edit: After letting it "charge" for about an hour I was able to turn the phone back on. It said the battery was at 30% but was draining like 2% every 15-20 seconds. Looking at the settings it said the battery state was unkown (where it usually says not charging or charging). Something is definitely doing on here, but I have no idea what. I tried rebooting to recovery from the ROM but it just shut off. Now it's doing the same thing again (0%, won't turn on). Ugh!
