Hi, new here but I've been lurking for a while.
I followed Powerpoint's guide to instal CM10 on my KF2
http://forum.xda-developers.com/showthread.php?t=2105077
Everything was running great and has been since I first loaded version 3 a few weeks ago, and last week i went to version 4 of powerpoint's rom with no problems. Then a couple days ago after i had been browsing the internet on it for maybe 30 minutes, I set it down and when i came back the screen was off and wouldn't turn back on. so i figured the battery was just dead, so i plugged it in to the wall charger. At first the charge/power light wouldn't come on at all. Then after several plugs and unplugs the orange light started to come on but would only stay illuminated for 30 seconds-ish. So I tried it on my phone charger and the orange light came on and stayed on, so i decided to let it charge overnight. The next morning the light was still glowing orange so I unplugged it and tried turning it on, but still nothing happens. But when I plugged it back in afterwards the light came on green. now it has been plugged in for almost a day with the green light on but it still wont turn on.
Anyone else have this problem? Any ideas what i can try? for obvious reasons i can't exactly ship it back to amazon lol
p.s. I have a final on friday and the text book for that class is on the kindle. So urgent responses will be greatly appreciated.
Nevermind guys, I figured it out. Power button for 20 and it booted right up

I've had this a couple of times on both 10.1 ROMs. As you stated the only way I got it working was to hold the power button for 20 secs, then power on normally.

It just happened to me again, seems to be a recurring problem. Anyone have a clue what's causing this?
on a side note, perhaps this problem could be dealt with simply by installing a battery management app like juicedeffender. any thoughts?

Wow, for once I can completely and knowledgeably help with almost no guess work!
The issue is Sleep of Death.
The cause is unknown, and due to the nature of how to reset it, it's been difficult to get logs. It happened to FMK not too long ago and last I heard he was going to get the logs (to find what causes this) and get those to Hashcode to look at potential fixes.
It's not battery related....well in the sense that, if it happened, you reset the device, and looked at the battery, it should be at a similar level to what it was before.
TO FIX
You guys were right on fixing it mostly.
If you ever press power a few times and it won't turn it, don't bother fretting about it. Just do the hard reset, which is holding the button down for 10 seconds. After you do that the device will reset to the point where if you just press the power button once, it will boot up like normal.
I would hold it down for about 15 seconds just in case, or if you have headphones it, you can here when it does the reset and can get used to the timing.
I would say....in a few weeks with the device, I've had the issue around 5-6 times.
I've also NEVER had it happen while I'm doing things, so it hasn't caused issues besides making me a wait a bit before using the device, which is good. If it happened during doing things I would want this fixed ASAP, but so far, no major issues.
agreed, if it was happening while i was trying to do stuff it would be problem. As it is though, I just consider it a minor inconvenience. Glad to know I'm not the only one experiencing this though.

I wouldn't call it a fix. I would call that a workaround. We need a fix, and I think if anyone could get an effing log to hashcode of it happening, we could fix the problem. I think it is a kernel problem, what with the recent merges and such. I think something is incorrectly copying from kf1 to kf2... if anyone understands what I'm trying to say, it makes sense..

I wonder if pulling the log cat via adb would work, I.e. wait till it goes wrong' then connect it to a PC to pull the log. The issue is its very random and being at a PC to do it when it goes wrong could be tricky.

the hard reset (power button for 20s) clears memory
When I was using this phone the screen suddenly turned black. No powering off or anything, the phone was nearly fully charged anyway. Nothing seems to be working anymore. I tried turning it back on but it's completely unresponsive. It won't even charge anymore. I was wondering if there was any solutions to this and if other people where having this problem or did my phone just brick itself
Are you able to get to the bootloader? by pressing volume + and power at the same time. It may be worth trying to flash stock also. I am no expert its just what I would try.

Hello there. I have the same problem, phone suddenly stopped to show anything on the screen, it is comleptely black. Tried to reflash few original roms, without a succsess. Replacing lcd did also not solved the problem. Did anyone find a solution?
Thanx
Did you try to format + reflash using spflash? Check out my video walk thru.

Of course I did. But at no avail. Today, I found out, that the new screen is partially working. I can see very dark picture, it means, I have no back light. Tried to set it up from engineers mode, but no luck.
So the new screen is on, but without back light, and the phone heats pretty much in the top area.

If so. Try to pull down the statusbar and swipe a bit under the statusbar line, in the top of the screen from left to right, with some luck you will tap the brightness switcher

I can connect to the phone through Vysor, and when I change the brightness level there, there is no change at all. The Phone does not react to any settings change at all.
Tried eragon rom, but still no change....

Better hope you still have your garantie, because theres legit no way to restore it. You just have to send it back for it to get fixed. This happened to me once and yesterday twice. sadly I am to dissapointed from this. I am never buying an Elephone again ! PS bro it isnt worth sending this hell of a **** peace back. It costs and the blackscreen thing is gonna happen again in 6-8 months. SO go out there and buy yourself a real phone not this bull****. I have to do the same rn.

Just happened to me with my 3 year old phone. Left overnight with enough charge. Pressed the side button and nothing - held it down to restart and then complete blank.
Repalced the battery about 1 month ago with one from AliExpress for £5.
So using the kit provided with the battery or a watchmakers screwdriver - undo the 12 tiny screws and remove the white surround and then the inner back with the phone's number on it. Next disconnect the battery socket but be careful as it is tiny - use a torch and magnifier if vision not good. Remove the sim card. Wait 10 minutes - did this with the blue light flashing - it stopped finally on disconnection.
Put it all back together and hey presto fully working phone
Hello!
Everything was working fine until my phone started acting up about 6 months ago. The screen began to become unresponsive, apps crashed when switching between them and random reboots occurred frequently. I thought back then it had to be software related, so I completed multiple factory resets, and completely removed everything on my phone. It became slightly more usable, but these crashed and random reboots still occurred.
Last week, my phone continued to reboot, but a new problem occurred-it no longer would turn on after the reboot. I tried plugging it into the wall, pressing the volume down + home + power to force bootloader mode, but it wouldn't turn on at all. The fix was I had to remove the entire case, take out the battery and put it back in the phone. After that it would turn on, but only for a few minutes before another random reboot occurred and I had to remove the entire battery again. My phone is now virtually useless as I cant before even the basic functions, calling and texting without it becoming unresponsive or shutting off and not turning on.
I narrowed it down to the eMMC chip. I am almost certain that is corrupt, because during some of the reboots it would fail and throw me into download mode with the error:
mmc0_read_fail
or something along those lines. My last attempt at recovering the phone was to the stock rom PE2 with a PIT file (I had created before I started flashing custom roms). Each time I would attempt to flash with ODIN it would result in a:
mmc0_write_fail
However, I was finally able to get the PIT and PE2 firmware to flash. Now I have a half-working phone that will randomly reboot still and in order to turn it back on, the battery has to be pulled out for a minimum of 15 seconds.
New Issue I just noticed: When the screen turns off when the phone is inactive, it won't turn on again after pressing the power or home buttons. Only solution to this is once again, pull battery and hope I boot into system again.
I am pretty sure there is no fix to this problem on the software side, but let me know if you have a suggestion! Thanks!
Same situation. This thing is a lemon!
Sounds like hardware failure.
Replaced the battery yet? My original didn't last fifteen months before it started shutting the phone down. It's the first thing I think of when someone reports having to pull the battery.
Are you checking battery capacity before the battery pull by plugging in when it shuts down? Mine showed 0%. Before the shutdown, it may have indicated as high as 30%. It gets worse.
You didn't mention capacity when plugged so I thought I'd ask.

One of my note 4 had same issue. Its a hardware issue. I was able to get the phone working by using a heatgun on the motherboard to try and reflow the solder on the chips. The phone works like brand new after the heatgun but the phone would only work for like 3 or 4 days before crapping out again. Ultimately ended up buying a used motherboard on ebay with a clean esn and its working perfectly again.
My wife's Note 4 started the random reboot thing and screen being unresponsive thing last week. She said it randomly started after installing Snapchat, so she uninstalled it hoping that would fix it. It didnt. I put a new battery in it thinking the original was bad, but still same issues. Then did a factory reset but that didnt work. After a lot of searching I stumbled on to someone who mentioned downloading an app called Wakelock. I did and phone has been running smoothly for several days now.
I also recently did the most recent update hoping that would fix the issue, it didnt but during the install I did get one error of emmc read failure or something like that. May just order a used/new motherboard just in case.
Just be careful when swapping out the motherboard as it essentially is taking apart the whole phone including the removal of the LCD.
This is embarrassing, but I was trying to install Pokemon Go on my G4 and the phone got really hot and rebooted. It never came back. Just went into a boot loop. I found instructions online on how to do a master reset with the power button and volume down letting it up briefly when seeing the logo and then pressing it again and letting it boot. I answered the question about deleting all user data and then answered it again. It said it was erasing data, then froze for a few hours at "optimizing apps" on one of the steps while I left it plugged in. I eventually pulled the battery to get it to respond again and now it just shows the LG logo and then goes dark. While dark it doesn't respond to button presses or let me try again to power it on, etc.
Any chance of me getting this phone working again? Is there anything else I can try aside from the master reset that I've already tried?
Hello if you look under the battery and your serial number starts with 505 or close its dead.

send it back for reapir.
hi, mine was 509. It died 2 weeks ago, showing only "LG life is good" if trying to boot it. No way into recovery. (did boot one time very slowly to lockscreen before the definitive death)
This seems to be the same for you.... dead CPU I suppose. I'm still waiting for the repair.
(curious about the 505 asserted here, since mine was higher)
Hello the first 3 digits of serial number indicate date of manufacture, and the early ones have a manufacturing defect.

Hello,
mine was 510 and died on me 4 weeks ago, (boot loop with only LG logo) as it died from overheating (or at least was very hot when die occured), I tried to cool it and it was "succesful"
It put it in the freezer for some time and then could boot it on TWRP and make a full backup (I left it in the freezer the whole time)!
boot at normal temp lead to black screen in 10-15secs. I sent it back for repair (motherboard replacement was made in less than 1 week by Lg France), I am now waiting the answer from Lg developer to unlock the bootloader again.
I guess you can at least try and see if you can have the same result as me.

Hello everyon everyone.
I have the SM-P600 version, everything was good until the beginning of the week when touchpad began to go off without reason, and completely random.
I first reinstalled several official ROMs from the most recent to the oldest, with no significant improvement
Then i rooted and tried Lineage, it looked good for a while, but in the end same problem.
Please note, when the tablet begins to mess, the reboots are occuring more and more often and after a while it turns in a loop and im not even able to switch it off.
Samsung logo display, black screen, logo, black screen, etc ...
I think rather for a battery-side problem, if some people have faced similar problem, I'm taking help.
Do you know if by chance we can use the tablet without battery to test this theory?
Thank you in advance for any answers.

I think I'd be taking a close look at the physical power button. Seems to me that if it had gone flakey it could cause something like this.

Hello and thanks for you answer,
Just to precise i never faced this issue while flashing an official or custom ROM, dont know if it is just luck or it can help in anything
Anyway ill try to check it the power button just in case
It's weird I just started having this exact problem myself. One morning I unplugged it and it had shut itself down overnight. Since then it randomly reboots. Sometimes I can get 20/30 minutes out of it, but once it starts, it can get into multiple reboots with the only way to stop it is to plug in the charger. I tried wiping cashe/dalvic (no help). Nothing was recently changed (including apps). Tried resoldering battery connector (battery was replaced a year or so ago with OEM Sammy). The P600 is rooted with TWRP installed, but no custom ROM. Usually the reboots start while I'm doing something (surfing, email, etc.), but I don't think it will do it while sleeping. I'm considering the power button, but I don't see this exact problem anywhere else, but this post. Any ideas?
OK. My tablet has taken a turn for the worse. Now it is stuck in a continuous boot loop. I tried the power switch, no help. I tried booting into TWRP, and it went back into rebooting before I could do anything. Strange thing is I can put it into download mode indefinitely without it rebooting. Should I ODIN back to stock? I tried the resoldering of the battery connection earlier. Any other ideas?
