Hi! Every time i turn off my p6800, when turn on don't see "samsung glalaxy tab 7.7" and the boot animation but start the "factory mode". I i turn off it turn automatically on after 4-5 seconds and visualize the "factory mode".
I try to flash with odin, but for the first boot it's ok, if i turn off the device and turn on the problem is the same.
anyone have this problem or know its fix?
I had this happen. I found that fully draining the battery fixed it, I haven't found what makes it happen in the first place though.
To completely drain the battery you'll have to turn it back on after it turns off from low power. I'd recommend doing the first big drain by flashing something in odin to get it booted (I just flashed recovery instead of the whole rom), then running it down till it turns off. Then power it back on, just the factory mode screen is okay now and wait till turns off again. This is to avoid having it on the factory mode screen for hours on end, which would probably cause burn-in.
Once it gives no response to pressing the power button, plug it in to charge, hopefully when it's charged a bit you can turn it on and it will be working again.
This problem made me really wish for a removable battery.
My son had this issue for some time ago. And draining battery didn't help indeed. But after about a week of this looping, it randomly became possible to boot through the loop holding the power button. And after a month or so, I can say that the device is almost self-cured the disease, and the "factory mode" is quite rare seen now=)

Hello. Please forgive my ignorance regarding the technical aspects of methods discussed on these forums.
I have a Samsung Galaxy S4 GT-I9505 supplied by Vodafone Australia. This was received today as a replacement for a screen issue I had with my previous S4. On the previous S4, I had rooted using a Saferoot method as read about on this forum. Later I had installed Xposed to use Keepchat and everything was fine. Today I have rooted this replacement phone successfully using the same method, and then moved to install Xposed. The Xposed application required an update, the very first option in the app was red and suggested an update or a reboot, and the reboot did nothing, so I pressed update. The phone turned off but didn't restart. I tried the usual button presses and battery pulls and finally a simple power up using the standard power button started the phone up. It got as far as the lock screen I believe, before shutting down again. It is now unresponsive. It wont turn on, enter the boot menu (multi button holding method) or charge. I believe the battery is quite low at this point, and unable to charge, causing me some consternation. It has now been over 30 minutes with no response.
If anyone could provide a resolution to this issue, I would be extremely thankful.
Regards,
CaleS

Hello again.
I have an update on my situation.
I left the phone on charge and it eventually turned on by itself. I played around with it for a while and it seemed OK. Eventually it turned off again. I had to pull the battery to get it to turn back on. After starting up again, getting to the lockscreen, it turned off again. This process repeated many times, until I got frustrated.
The next day I thought I'd try a factory reset via volume up + power, and the device managed to stay on long enough for this to complete. After the phone reset, I used it for a while and again it turned off. The same cycle continued.
Perhaps the phone is naturally faulty, despite my rooting attempt, as it was a refurbished model. I am quite happy to return it for another replacement under warranty, however I may not be able to do it as the device is rooted. I would gladly remove the root using stock firmware and Odin, however the phone resets after a few seconds of entering download mode.
Any advice?
Thanks.
Sounds to me you have a faulty power button. It's somehow stuck that's why it even reboots in download mode. It's a common problem for the S4. Try to wedge it or replace it.
if it is refurbished model it might as well be dead battery.
battery sensor detects "low battery" state and shutdown phone saying battery 0% - to protect battery against fully depleted state (damaging to max capacity or even impossible to charge at some point)
if you power it on again it will boot and say it has like 1% left and you will be able to use it for few more moments, but doing so will degrade your battery.
powering it on, going to lock screen for it to shutdown on its own again sounds like weak power source
imagine above scenario happening several times (previous owner of the phone kept "reviving" it after shutdown due to battery 0%)
that would resulted in battery able to hold only fraction of its standard power - allowing you to just boot your phone before it shuts down.
I had similar situation with my laptop battery (this one was on AC all the time) - battery was so damaged that laptop was shutting down at windows login screen - if booted on battery alone.
When booted on AC and unplugged it said 100% battery, that went down to 0% in a matter of around 2 minutes, when laptop shuts down.
My S4 has finally kicked the bucket. It turns on long enough to display the "Samsung" splash screen with the padlock icon that says "Custom." After about two seconds it instantly shuts off, and can't be turned back on.
Pull the battery, the phone automatically turns on, shuts off again, rinse and repeat.
At this point I just want to salvage my pictures and music from the phone; is there any way I can mount the internal SD in the state that it's in? I'm sure this power issue is hardware-based; I can't get into recovery or download mode before it shuts off on me.
I was having this same problem recently as well. It happened on two separate occasions with about a week in between. The first time it came back after a few battery pulls and attempts to boot to recovery as well as download mode. The second time I fiddled with it for about an hour with numerous battery pulls and attempts to boot to recovery and download mode. I even swapped batteries to no avail. I don't know why exactly it finally decided to boot, but I haven't had an issue with it since. Maybe keep trying and hope for the best?
Can you boot and stay into recovery or download mode?
If not, then it very well might be a button issue. Have the phone checked out or you can do it yourself with a voltmeter if you have the knowledge and tech. Otherwise take it to a professional. I paid around 15$ to a button replaced. Which kinda seems a lot, considering a set of 4 buttons costs about 5$ and then you can do it yourself since it doesn't appear to be that hard, especially if you've done soldering before.
So, I have a Samsung SM-T230NU. When I tried to power it on, it flashed for a split second the Samsung Galaxy Tab 4 logo and then went blank. I figured it was out of juice, so I plugged it in and let it charge for an hour or so.
When I came back, it was flashing and going dark.
I tried a different cable. As soon as power was applied, it flashed and went dark again.
Now, the boot logo is showing for an even briefer amount of time.
I am suspecting the battery or USB port. I don't have parts readily available to swap, however.
It may be worth adding, when I plug in the device, without touching any buttons, the screen starts flashing the Samsung Galaxy Tab 4 boot logo. I would guess a stuck power button, but the power button travels freely. When I unplug the tablet from the computer, the flashing stops.
Trying to boot it with power + volume up garners no response from the device.
Any ideas?
Having same issue here
Tried hard reset, no dice.
Tried opening the back to see if I can identify some loose connection, didn't see anything funny. I am not an electrician.
My sister's having the same issue with her T230NU. It still boots (it'll boot to the Samsung splash, but then it flashes off the screen in half a second; this repeats every 7 seconds), but only if it's plugged directly to the wall charger. She let it sit overnight to charge, and it's still got this issue. I'm pretty sure her battery was drained when the issue started occurring last night, but it doesn't look like the battery has charged much (if at all) since then.
I have a galaxy s4 (i9500) and got it in used condition, a year ago. Never suspected a single problem in it.
Today I powered off my mobile for charging then after 25 minutes I took it off. I held the power button then I saw my boot logo(Where there is written Samsung Galaxy S4 GT-i9500). That logo kept showing as usual for 2 seconds and screen went black and again that logo appeared for 2 seconds and screen gone black and again it appeared, so, I'm stuck in kinda loop not a bootlooop exactly(maybe because bootloop refers to being stuck on boot screen while in my case its boot logo). I then removed the battery and inserted it back after an hour and as soon as I inserted it back the mobile itself turned on as if I held power button but this time again I was stuck in that loop. Moreover when I tried going into download mode, I didn't even need to hold the power button along with the volume down and home, it itself proceeded to confirmation screen of odin mode. And after that confirmation screen appeared saying that whether I really want to boot into download mode, disappeared itself after like 3 or 4 seconds even though I didn't press any key. And in case I press vol up key confirming to boot to download mode, then it again takes me to that loop. I'm too much confused . I can't even flash the firmware as it won;t boot to download mode neither am I able to boot into recovery.
Now do u really think the problem might be the power button(Which is maybe stuck in the state of pressed).
Or else it can be the battery coz my battery is also just average not too good?
I also inserted the command( in build.prop file) for enabling nav. bar and the code was correct but I never rebooted after inserting that. this was the first time I rebooted after that.
SOrry for some bad English.
Do you have something like this? I'm now having problem with getting my phone back to work...

From what you say it seams like power button problem, try to start the phone and connect it to the charger. When it start take out the battery, it will be powered by charger and you will eliminate battery problem.
I have recently faced this issue that my poco m3 is not turning on, completely dead. I have encountered this issue 2 times now, so I applied the usual method, I waited for 2, 3 days to drain my battery out so I could use it again.
The third time I drain my battery out so I could flash other firmware. But in the process of unlocking the bootloader, when I turned off my phone so I could enter into fastboot mode, my phone is dead again, neither turning on nor going into fastboot mode.
I have now also realized that I cannot turn off my phone, or else have to wait for 2, or 3 days to drain my battery out to use it again. Now I'm tired as hell and have no energy left. Is there any way to enter into fastboot mode without turning off my phone?

Phone on, keep the power button pressed and volume down, the phone restarts, at the vibration release the power button.

Will sure try that, hope it would work.
Though It just came into my mind that next time instead of just turning on my phone, If I directly go into fastboot mode? Would it be possible after draining out my battery?

you can
Try with charger plugged in,but flashing a rom with a discharged battery is very risky.
