[Q] Mt4G won't boot AT ALL

I went out for a while with my battery at 20%, when I came back it had drained out. I put it to charge, but when I tried to switch it back on, it refused to boot. On a normal power button press, it would vibrate 3 times and then the red notification light would start blinking. Same thing with power + volume_up. If I press power + volume_down, it would vibrate 5 times and the green notification light would stay lit. Nothing comes on the screen, whatsoever.
I was rooted with S=off, and was using the Operation Inferno ROM (which I have been using comfortably for the past month or so).
I did try some stuff with ADB, such as using it to reboot into bootloader and recovery (same 3 vibrate + red notification light), pushed the Operation Inferno ROM again to the sdcard and tried to restore the ROM from that location (for which I got adb: unable to open file /sdcard/backup.zip).
I haven't yet gotten around to downloading and installing the factory image some have suggested for the eMMC issue (PD15IMG.ZIP) but I wanted additional opinions considering most people with an eMMC issue have been able to open HBOOT at least.

When the phone doesn't power on, neither ADB nor fastboot will help you. There is no device on the other side, so all your attempts went to the drain, and it was expected. Nothing to do with eMMC issue or anything else. Your phone just doesn't power on.
Put your phone to charge, if the light turns orange - just leave it to charge until it's green, then disconnect and try to power on.
If the light doesn't turn orange, or it doesn't power on even after charging - remove the battery for 10 min, press Power button for 1/2 min, release the button, reinsert the battery, put to charge. And again, let it charge before you try to turn it on.

I did charge it earlier (for about half an hour or so) and the orange light does come, but it didn't boot after that either.
I'll just give it a try by charging it through the night and see.

I think a key thing is to take out your battery for 10 min, as Jack_R1 suggested. Then proceed with the charging.

Still doesn't work. I dissembled it and kept it like that for quite some time, then put everything back and charged it for hours. Still the same issue happening during boot.

Connect the phone to USB, powered off, see if the PC recognizes "QHSUSB_DLOAD" device. Try to power it on, see if it happens.
If it happens - it means your primary bootloader is screwed, in another words - no repair (actually, repair is theoretically possible, but no guide, no information and no sources exist for MT4G).

When its plugged in, its recognised by the ADB (even when powered off), and I can do some basic commands (mentioned in the first post). When I power it on the same thing happens as when it wasn't plugged into USB (ie, the vibration and the blinking LED).
I'm also worried about water damage, since a very tiny amount did come on it as I was sweating profusely. Although the indicators in the battery tray and on the battery itself don't signal damage (they're completely white) I've just decided to try and keep it opened up in a bowl of rice, just in case, until someone is able to come out with some idea.
As I'm in India, taking it to T-Mobile is not an option. If nothing works out, I might take it to HTC and see if they can help out.

Nexus 10 won't boot after charging

Hi guys,
My battery went completely dead, left it to charge over night, now wont boot at all. If its plugged into the charger and I hold the power button the full battery symbol (black and white) shows for about 2 seconds and then goes off for about the same time then reapers. Any ideas?
Device status:
- Stock rom
- boot loader unlocked
- non-rooted
I've tried :
- Hold power for 30 seconds to a minute
- Hold power + volume buttons for 30 seconds to a minute
- no response form my computer when its plugged in
- no response when trying to boot into fast boot
I am aware this has already been asked. I've tried the other threads but no luck
EDIT
I got mine to boot. I have literally no idea how, I just tried the power button again and it burst into life, although the battery was empty.
I think this could be due to not letting the battery die enough. I normally let my phone (HTC One) so completely flat every month or so but i've never done it for the Nexus 10.

The same problem please help

Serious bump. Ive tried all of these methods, but it just shows the charge icon when plugged in. This is the first time for me that it wouldnt just turn on after going into that sleep state. Charged over night.

I think this is the same issue that many (or a few) people are having. Mine, for example, will be at 100% charge. Then, sometime in the day (without using it) it will die. It will not power on. When I plug it into a charger, it will show the charge indicator on the screen, and I can get it to power on 50% of the time right away by holding down the power button for about 5-10 seconds.
When it boots up, the android tells me it is at 0% battery. If I leave it plugged in it will usually show 100% again after a short period of time, but until then, if i unplug it, the tablet powers right off.

Here is a pretty good thread to see the issue.

Here's a question for you:
Watch your battery life. At any point, does it begin NOT draining? Such as remaining at 60% for 2-3 hours during usage? If so, you may have a defective motherboard and require warranty replacement, as that was one of my symptoms.

Restart loop

By the coincidence, is your batt serial no beginning with BD? If so, look on the battery. Is it swollen a bit? If so - call samsung, they will replace battery free of charge.
If not, try to connect phone to charger, insert battery, go to recovery and make full wipe.

it might be a power button issue

ok, this may be tricky.
while keeping volume down and home - slice battery in. If phone would boot in download mode (even just for a while) - then it will be power button issue.

it boots up on download mode for seconds and then powered off again....

Im digging up this post because this is the same problem i had.
I ended up removing the power button all together, carefully popped it off the motherboard. The phone no longer boots for a couple secs and powers off again so i think the power button was the issue. Now i have the problem of powering on the phone. I tried booting into download mode (to have the reboot option) by holding volume down+home while plugging it in but nothing happens, all i get is the battery charging icon. Ive been into download mode before i removed the button, but like the OP, it would only be a second or 2 before rebooting. Am i doing the correct procedure for download mode? Perhaps my timing is off? Any suggestions?
At least i do get the battery charge and it stays until i unplug the phone, no more boot loop!

Ok so i managed to get the phone to power up without going into download mode using this method i found on youtube. No boot loop and fully powered up now, the only thing is that im stuck on the lock screen. My friend cant remember his pin so i cant get in, the only option left now is to boot into recovery and do a factory reset yes? Well, how can i do that without a power button? Any suggestions?

phone won't boot/start up

I have a at&t S4 that all of a sudden today stopped working. When I restart the phone by taking the battery out and putting back in, it gets stuck on the Samsung Galaxy S4 logo and then a black screen. I tried going to recovery mode(volume up + home + power button), and it shows recovery booting in blue for a sec then goes black. I tried for download mode the warning comes up but after pressing volume up it goes black. I really don't know what to do at this point.

Tried using kies or smart switch to perform a firmware recovery?

Yes, the computer doesn't recognize that the phone is connected. It's as if when the phone goes to the black screen its actually powered off. The only time I get anything from the phone is when I pull the battery and reinsert it.

When the phone battery are too low, the phone could behave like that too.
Do you know that battery is fully charged or has more than 60%?
If not charge the phone first.
Plug the charger. If you did not see any sign showing that you phone is charging, press and hold the power button for 10 sec and release it. You should see the phone charging image.
Let me know whether your phone has enough battery power left but showing the above mentioned problems.

Yes, the battery is fully charged. I have another S4 Active that I've swapped the batteries with, along with a spare official Samsung battery and charger. It doesn't matter which battery I use, the phone acts the same with any of the 3.

If you have enough battery power left but the phone was behaved like that, you might need to flash the firmware.
Are you in lollipop or kitkat? For the time being, the only firmware available for kit-kat and lollipop is NB1 firmware cooked by muniz_ri . You can get it from here.
You mentioned that you can go to download mode but the phone shut off when you press volume up to go to the download mode after the warning.
Try the 10 sec method. Go to the download mode (power+home+volume-down) but keep holding the power button for 10 sec even though you see the warning message appear. Then you press volume up to go the download mode. Try this way and let me know.

It was on Kitkat. I can press the volume up and get it to show the download android screen but it immediately shuts off. Holding the power button for 10 secs. and then the volume up didn't do anything. The phone shuts off after 1-2 secs. of doing anything.

That is strange. The same thing happened to me. But I avoided the phone shut down by 10 sec methods.
Just hold the power+home+volume down for 10 sec, even though the warning sign show up, and then let it go all of them. Plug the phone to the computer and then press the volume-down to go into download mode. It works for me. Not on the first try though.
Try doing that with batter charger plug in too.

Thanks for your help. I figured out whats wrong, its got a faulty power button. I took the phone apart, put it back together, and was able to get it to boot completely. The slightest touch of the power button causes it to reboot though, so I'm going to need to replace it.

Glad you found the problem. I was trouble shooting for the software error.
Yes, power bottom could give you a problem too. I use screen off app so I do not have to use power button to turn off the screen.

Phone won't turn on

I was trying to fix my phone because I was getting a System UI stopped working error message (another previous post).
I went to turn it on today and nothing... phone is dead. I push the power, and combination of vol buttons, hold, press, etc... nothing.
even when I plug in the power cable, I don't even get the "Charging" icon coming up.
any ideas?
this phone problem went down hill really quick.

Try to hold power button for over 10 seconds.
If doesn't help at all than try different charger/cable.
Leave it on charge for a few hours as when battery is completely discharged it may take a long while to start up
