Greetings fellow geeks.
i have a problem with this i9500..
it was working fine, suddenly it resets.
it keeps resetting every 4 seconds.
won't let me go to recovery.
i can go to download mode. but it won't respond to volume button, and resets after 4 seconds.
i have a custom ram on it.
if i place a battery back in, it will power on and keeps resetting every 4 second.
what should i do?
Maybe your power button stuck in? But if you can enter download mode then not I guess. You can always flash original firmware if you haven't necessary data on it.

Ok sorry my friend, read that you can use download mode well. I think there is something with your power button. Did you drop your phone? It shouldn't reset every time in every state, that looks like hardware failure. You can easly open your phone with little screwdrivers, but you will lose your warranty. If your power button is broken you can always order new ones from China, I did it with $1,3 (power and volume).

100% your power button is stuck. Try to wiggle it lose or replace it.

TNX mate.
if i may say something, the button isn't stuck.. it's pretty clicky and sounds like working fine. is it possible the cause is coming from something else?

No it's your power button for sure.
I had that issue with my S3 LTE. It is indeed the power button since it does exactly the same that my did, try to use some alcohol in a swab and pass on the button (let it penetrate the button area, next click several times to try to clean the button from inside).
Good luck.

I have the same problem with my i9505, I always fix it like this:
1) remove the battery
2) let the phone rest w/o the battery for min. 10min
3) put the battery in and try to go in recovery
4) if you can wipe cache and try to turn it on
If the problem happens again:
1) remove battery
2) short the pins like this x/-/x/- , then x/x/-/- and then -/-/x/x (x is the connected pin) with something that conducts electricity like a metalic ring or high resistor or s/t
3) do step 3) from the previous one
(Anyways what you do is that you drain the capacitors in the phone, and on the power button, that capacitor is the main problem)
If that doesn't help, then try to leave it w/o the battery overnight
EDIT: well that is not a permanent fix, the fix is probably that you need a new power button, or in the worst case a new phone

Guys, thanks to all of you - especially frysee, who was a big help via Gtalk - the biggest part of my problem is solved:
My Transformer is still bricked and display won't turn on, but I was able to go back to stock ROM and wipe all personal data. So I won't get any trouble with warranty
If anyone is interested, me or frysee could write a How To for returning to stock ROM and retrieve warranty when screen is dead.
Thanks again!

Hi Guys!
I have a problem that is pretty common over at MoDaCo, but I haven't read anything about it here.
My Transformer sometimes doesn't turn on or wake up from sleep mode when turned on already. You can push the power button endlessly and nothing happens. Then suddenly it'll turn on as if nothing had happened.
I had this problem the first time right out of the box, so there's no bad software installed by me, don't know what ASUS did though. Perhaps it's one of the pre-installed apps.
As I said, normally it eventually comes to life again, but now I couldn't turn it on for a whole day! After I had no success, I left it on the charger over night, but still nothing this morning.
I feel I tried everything, pushed Vol Down + Power to go into recovery, pushed Vol Up + Vol Down and plugged USB to go into (useless) flash mode just to see the device to something, but no.
The only things that happen, if I push power:
- if I plug USB, the Windows plug and play sound plays and if I force shutdown the Transformer again (long-press power), the unplug sound plays. The device even appears in the Explorer and I can access SD card, but it only shows empty folders, no files in them.
- When I force-shutdown the device, I hear an internal "click" sound, similar to the one when you switch from front to rear camera, and you hear the speakers turn off. So it seems to initialize everything and stuff...
But all the time the Transformer screen stays dead
Any advice? Really need your help here guys! At MoDaCo there's no answer so far...
Regards,
qwer23
I was initially having this problem with my Transformer (it would usually happen when it had gone on standby and it couldn't get it to turn back on again) until I ran the ASUS updates on it - have you been able to update your Transformer on the occasions it did turn on for you?
If you've rooted it and stopped the OTA updates going onto it, you might just have to undo that and get an official ASUS firmware build on there to help fix the problem.

Hi!
First of all, thx for your answer.
Well as I said, the first time the problem occured, the device was out of the box and untouched before. So I don't think it has to do with something I did.
For me it normally also happened when device was in sleep mode, except the first time out of the box
I installed a custom ROM + Clockworkmod Recovery after that, hoping it'll fix the deep sleep problem. And it really didn't happen again - until now
I didn't turn off OTA updates as I first saw that thread when the device was already dead Perhaps it tried to OTA update itself but I guess I would have to confirm this manually right? And I didn't do that...
Reflashing another ROM or the stock ROM was my first idea, too. But hell, I can't even go to recovery! No matter what I do, press, plug or unplugg, the screen stays black!
Nice, another german Transformer
"playing the plug and play sound" means you propably have adb access? Tried getting a logcat?

Ahh. I didn't realise the screen was completely dead, I thought you had it working some of the time as had happened to me.
If you're seeing it in Explorer, maybe it is just a hardware failure and you'll have to get Asus to look at it...

no i guess that it is indeed the same thing that happened to you, sometimes it worked, sometimes not. only this time it doesn't come back from the not working part I guess you see yours in explorer too if it troubles to get out of deep sleep. i guess it's just the screen that sometimes doesn't turn on for all with that problem. but for me it doesn't even turn on for booting

It's possible. I don't think I tested connecting it to the Explorer while the screen was off, I assumed it just wasn't on.
Can you test it with the HDMI out and see if that shows you what would be on screen?

When it seems dead, try holding the power button for about 5 seconds (or whatever time you hold it for when turning it off)
Leave for about 2 minutes then hold power button again (like you do when turning device on) and it should boot.

I guess so
I'm getting a mini-hdmi cable today to determine if the screen is broken, because i have the feeling that ***** is booting but not showing anything...But I'll have to send it to ASUS nonetheless. Has anyone ever sent a device in for warranty reasons with custom software (CWM, Custom ROM) on it? What kind of trouble will I have to face?
I'd say try it with the HDMI cable, see if you get anything up on it and if the touchscreen/everything else still works, see if you can get the latest official ROM on there, see if that fixes the problem.
If nothing else, you can then send it back with an official firmware on it.
Try holding the power button for 5-10 sec, then press power + volume down (might be volume up - try both) together for another 5-6 sec. You'll get to a reset screen where it asks you to confirm if you want to wipe everything. press volume down (I think!! - read the screen carefully) instead to boot normally.
hope this helps
Its 10+ seconds for a full power off by the way, nothing shorter than that. If you changed any system files either by flashing or by pushing via ADB then you will have invalidated your warranty. Unless you can restore it to the way it was before you fiddled with it, you'll have an expensive paperweight.

Big bummer And sadly there are no "ASUS Stores" around where I could use a stupid employee who has no clue and is convinced it's hardware related.
Well I don't have my HDMI cable by now and will try this first, but if that doesn't work:
Can someone give me a step-by-step how I can access the restore function of CWM without seeing anything on my device? I did a backup in CWM before installing the custom ROM. Perhaps tell me sth. like this: "press power+vol. down on start, then after approx. x seconds press vol up, wait a bit to make sure CWM started, press vol down twice, to go to recovery, ..."
And can someone do the same for the stock recovery to reset the device? Perhaps there's a chance that a failed OTA update deleted CWM an there's the stock recovery.
I know the chance to save it like this are small, but otherwise a lot of money is lost
Regards,
qwer23
On the flip side however, you could probably make some money by being the first to dismantle your device, and sell the photos of the internals to some website like iFixit. Then you could also sell it off as parts on eBay. Obviously it might take more effort than you are willing to give it, but at least it's another option.
If you do decide to open it up I would love to hear what mA rating the battery has on its label. Not being able to find out the actual proper rating from any site has been driving me nuts. I believe it's 6800mA but im not 100% sure.
Anybody knows what's wrong and how do I solve it? Here's the entire story (if it helps):
I went to Play and updated my apps. I press and held the power button and selected "restart". (I restart my device regularly) However, after shutting down, it does not boot at all and no matter how many times I press the power button it just wouldn't boot up!
I tried charging it too. Nothing happens even after plugging in.

Can you get to the boot loader, if so, try to wipe data from the recovery within the boot loader.
Or else leave the battery to drain fully , this will solve your problem and the tab will boot.
This happened to me couple of weeks ago and draining the battery solved this issue.

Nope. I wish it did.
Try to hold the power button in about 4 or 5 seconds. I doubt it'll do anything. It sounds like there's a problem with power button or hardware.
I had a thrive 7 before I got my gtab 7.7 and my first one I exchanged because of a problem identical to yours. It was very sketchy to power on.

Only alternative left to leave it till battery drains, if you can remember the battery percentage before this happens, otherwise i am out of solutions.

Did you try a battery reset? With the phone off, can you get into either Download or Recovery mode? That would eliminate the possibility of an OS issue.

My power button is not working to turn the screen off. Long press works to bring up the power down menu or to do a hard shut down. It works to turn back on though. Seems to happen after I plug it into the wall charger. Restoring a nandroid backup fixes the issue.
Not sure if it's related but my PC's USB crashed after trying to plug the phone in and use USB 3.0 to transfer files. I had to refresh my W8 PC to get the USB working again.
I have the Sprint version, rooted and running JellyBomb.

I have the same problem. my power button is done for. whenever i need to start it. I plug it in and go into recovery and reboot from there. I also use this https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenoffpro&hl=en for screen timeout and lock. And you can also get exposed and gravity box and there is a status bar tweak to double tap the status bar to lock screen (put phone to sleep).
I tried everything then found the solution on another website
My note 3 has been with me for almost 2 years now and it's power button stopped working about 2-3 months ago. Until now I avoided draining the battery below 2% and was fine but just today I dropped my phone and it shut down. I knew that my power button didn't work because of hardware problems so a soft reset didn't work for me. What I found however is that if your power button is dead you can just very quickly remove and re-insert your battery and your samsung device (I have no idea if this works on other brands) automatically boots itself. I'll give the link too incase I wasn't clear enough and I hope this helps people who shared my worries.

My wife's N7 sometimes starts normally, but very often you have to press and hold the power button for at least 15 seconds before you get the boot screen google logo.
I have searched but not found a thread dealing with this issue. I do not have the powering off/battery status issues, the tablet ALWAYS boots up, just that it seems very odd you have to press and hold the power button for so long sometimes. EDIT... HERE is a similar thread.
Any ideas if there is some fix for this?
The tablet is on Kitkat OTA update.

Your device is not shutting down properly. For me if i load a bad kernel or do some thing nasty in kernel settings then device some times goes into sleep of death. It is on but not responsive. You are just pressing power button for 15 sec to reboot it. Plz update your kernel if u have custom kernel or check settings if u have changed any. And if u haven't done any thing then start paying attention to apps after which these problems start to happen.
Factory reset would also fix the issue.
P.s: do not undervolt if you are and if custom kernel then try increasing lowest cpu state frequency to 200+. Just a thought. Not every device can handle all kernels.

Ok, thanks BL4CK...
So that seems to point at HARDWARE being the problem... since after Factory Reset it cannot be software, and since I have STOCK kernel STOCK firmware, it cant be the ROM...

Same here...device is untouched, no root, no custom rom etc.
At first after unboxing i thought the nexus was doa, untill i realised that you have to keep pushing power button for 13 seconds!
What i hate even more: it's still on 4.3 because OTA updated doesn't work!
-update notification appears
-downloading update
-confirming "restart and install update"
-nexus turns off
I would really really appriciate some help!
PS: i do NOT want to update via usb to computer connection
Here is a thread with some good fixes for the hard start problem (hardware problem):
http://forum.xda-developers.com/showthread.php?t=2090826
If an app was causing SOD when shutting down, a factory reset would resolve it.
Should also check bootloader to be v4.23
Start the device by pressing n holding PWR + VOL DWN until you enter the bootloader.
The info should be somewhere along the left-bottom side of the screen.
Once u get the version number, use vol up/down buttons to navigate until u reach power off.
Press power button to confirm power off.
Start normally/whichever way currently works for u.
Used to have this hard start problem alongside touchscreen problems.
Under the nexus's back cover are actually some antenna pins along with some grounding pins.
Sometimes these pins corrode or have poor contact, then it causes some electrical abnormalities.
Try to clean these pins with an cotton earbud and some metal cleaning solution. Stuff like carb sprays for example. Nothing oil based. Wet the bud a little with your solution and clean gently. Then use a dry bud and gently wipe dry the pins and all residues. Repeat a few times if needed.
Also try to push the pins outward so it will have more contact with the back cover.
!!Be very gentle and use minimal pressure, these pins break easily and if they do you will need a new board.
Other than that, check the battery connector too. Unplug and replug. Or other suggestions/solution in the thread above.
Good luck!
Word of advice be extra careful when messing with bootloader. I have seen many loss their devices because of simple yet stupid mistake.
Please ignore my spelling mistakes, English is not my native language and i hate on screen touch keyboards.
hi guys. today my galaxy s4 suddenly rebooted and now it cant get past the galaxy s4 screen on boot. it automaticly gets into this screen for several seconds, then a black screen and then again. also, when i put in the battery it automaticly starts, and gets in this loop.
i searched the forum a little and i suspect it is somthing with the home button. do i need to replace the whole display to fix thix? or what should i do.
And some important infomation, my home button is a little bent for the last 5 months, but so far it had no problems.
Have you tried to start recovery or download?
Remove the battery, wait half a minute, reinsert the battery and push at the same time Vol Up+Home+Power keys.
If that works you may wipe Cache and Dalvik Cache and maybe it will boot normally again.

Try pressing it in various ways or open it up to see if it is stuck or not..

power button or home button..? power button looks fine but home is bent and not working for a while.
I agree with @DeepankarS. Seems your power button is stuck.
If so it is a good reason to have the bootloop. Please double check it.

there is a huge difference mate in being okay and looking okay
Thus is not the first kinda problem..the download mode rebooting is directly liked to it..because the download mode will never reboot without the power button being pressed (exceptions ignored)
Try tapping it on a flat surface too...not hard..but ya..
Or search..how people released the stuck power buttons here..
