I'm fixing my friend's phone that she got in a bootloop, it would stay on the logo for about 8 sec. go into a black screen for about 5 sec. then go back to the logo for 8 sec again, and so on and so on. I messed with the phone for a little bit and found out it did the same thing charging, loading/battery icon for 8 sec, black screen 5 sec, etc. So I read up on ODINing it, and I got it on download mode no problem, my computer and ODIN detecting it, but again it only lasted for 8 sec. then it went into the black screen disconnecting it from my computer, then it went into charging mode doing the same thing. If I hold the track button and the - volume button it would stay on download mode, but it would still go to the black screen and keep on repeating the same cycle. I took out the sd card, sim card, and tried a different battery, still the same. Anything that could help me please
i bought a phone real cheap thinking i could fix it, but it was doing the same thing: showing the Samsung logo for a few seconds, then going blank, or going into download mode for a fews seconds, then going blank. if i took the battery out and put it back in, it would automatically start looping like that, without even pressing the power button. there was no way to fix it at all that i could find, and i looked all over. i ended up contacting Samsung and the phone was under warranty, and they fixed it by replacing a component(that's the only explanation i got). somehow something had gone wrong with the hardware i guess.
Edit: there was one thing i tried that was said to possibly fix an issue like this, and it was to unscrew the back housing and go down to the motherboard and check the 3 or so ribbon cables that attach to the board.... and just to make sure that the connections were nice and tight. i did that but it didn't fix it for me.

I have a rooted stock phone that stopped working for no apparent reason (no new ROM flashed, no configuration change). It starts, shows the Samsung logo, and immediately reboots. I tried to put it in download mode, when i hold the 3 keys I see the download logo showing up, but it reboots after a few seconds anyway. after a while it will start looping through the battery charge screen (which shows the battery as empty). I tried 2 different batteries with no change. Any idea how to get something working again?
That almost sounds like some sort of power issue. Have you left it sit turned off until the battery was full?
Yes, I left it overnight and it just keeps flashing the battery screen and then resets. I also have an external charger and used it to charge the battery, so it's not an issue with the battery actually being empty.
Have you been able to get the phone into download mode previously?
Have you have dealt with a boot loop and performed an Odin recovery previously? If not, remember it can take a few tries to get download mode to pop up.
If you can't get Odin to go, you might try flashing with Kies.
I am wondering if your phone met with some kind of disaster when you weren't around (trauma or liquid).

This sounds almost exactly like the problem I had with my Sidekick. In my case, it turned out to be a bad battery and a loose ribbon cable on the motherboard. I'd check those two things.
This happened to me as well, and the three-button method to get into download mode wasn't working. For some odd reason, for me to get into download mode all I have to do is hold down the power button + track pad, and it goes right into download mode... Maybe slightly different model?
Try that - power button + trackpad
Bootloops.
Not a guaranteed fix by any means but for troubleshooting purposes you may want to consider making a USB JIG. It will most definitely help you figure out just how serious the problem is and if it IS software related with a way to get it working again you will need the JIG anyway so its worth a shot. If nothing else you learn a new skill and you're the proud owner of an incredibly useful tool that you can say you made yourself. good luck!
I know this post is kind of old, but it just happened to me last week (same circumstance, a rooted phone, but stock). I ended up just pulling the battery out and pressing the power button a couple times to hopefully drian it and letting it sit for 15 minutes, and then I put the battery back in and it worked again. I now have another rom flashed on it, I hate stock.
I know this forum is ancient, but I'm working on an E-Bay phone with this exact issue. I found the following thread the most useful and informative on the problem:
http://forum.xda-developers.com/showthread.php?t=1996709
Hopefully this helps other.
what i did was hold the power volume and button between the menu n back with the left hand YES HOLD IT UNTILL THE PIT IS UPLOADED. then u can let go then slide in the vattery with the right.while checking off the flash bootloarders on the heimdall with it fixing my phone XD
I had this happen, I dissassembled the phone, and used an alcohol pad to clean the power button area, and manipulated the button a lot, let it dry, reassembled...it still bootlooped.
BELOW IS RISKY BUT WORKED FOR ME
So while the back cover was off (exposing the cicuit board but everything still connected) I inserted the battery and watched it boot loop...during this, I used a flathead screw driver to "short" the power button pins...this let it boot fully, and it has been fine since.
i smacked the phones power button a few times and it worked
So today, as i was on my way to work I accidentally held down the lockscreen button and the power menu popped up (I was on Glorious Overdoes V2) in the middle of a text and i pressed reboot accidentally... My phone never rebooted... It was stuck on the black Sidekick 4G/T-Mobile screen and then it would go black, then once again that screen would pop up... I removed the battery and put it back in, and without me pressing any buttons the same screen came back up... I let it sit for a while and after 20minutes nothing changed except the phone got really hot. Luckily I had my OLD Nokia in my car and popped my SIM card in it so that i could continue having a phone. I let The Sidekick sit for 4hours and it was extremely hot and then eventually it just turned off completely (Im assuming the battery drained, it was at 90% 4 hours before.) I got home, plugged it in and it wouldn't even turn on the charging screen. Somebody told me that my Motherboard is fried but I don't know. I called T-mobile and they're going to send me a new phone since it's still in the 1-year warranty period.
Anyone know if they're going to be able to inspect my old device and find out if i rooted/flashed it? because i can't get into it or anything to ODIN
I feel like they will try putting a new battery in it, and if it still wont turn on you should be fine.
It got hot because the CPU was churning over something and couldn't enter a low power state. I bet you could coax the phone into download mode and reflash it.
what do you mean coax the phone into download mode? by using the button combo to get it into download mode when turning on? I've tried that and it doesn't work. I tried rebooting into recovery and that wont work either. Also, it wont charge the battery anymore...
I've always had a hard time getting into download mode, and my phone works fine. I just spent 5 minutes trying different combinations until I got it.
I've heard people say trackpad-power button, volume down-home-power button, volume up/down-put battery in-plug in USB, etc etc etc. But the only method that works for me is to put in the battery, plug in the USB, wait for the charging screen, then hold volume down-trackpad-power, releasing power as soon as the screen goes black
You say your phone is turning on as soon as the battery is inserted? What if you have it plugged into USB first?
I had the exact same problem, I sent it into samsung and they just replaced a part(never told me which one) and it was fixed. I did noticed that when the sccreen was poped open to show the keyboard, it would stop. But it's probably a loose cable like I've read before.

Worst case scenario if you can't figure it out here on XDA, you could always sell it on eBay for parts as defective.
So, tonight I just turned my screen on and then off real quick to check if I have any messages and set my phone down. Then I look down and see the Samsung logo. I'm a bit confused and notice that the Samsung logo keeps showing for 1-2 seconds going black for 1-2 seconds and then back to the Samsung logo for 1-2 seconds, over and over. I pull the battery and then when I put it back in, the phone starts doing it again before I touch any buttons. Clearly something is causing my power button to be "on" continuously. This seems to be a relatively common problem from doing some searching, but most of the posts I find seem to be full of people responding who fail to understand the problem. People seem to think that this is a boot loop and that it can be fixed by going into download mode. This is clearly not the case, the problem is obviously with the power button since the phone automatically starts up and keeps doing this as soon as the battery is reinserted regardless if no buttons are pushed or all buttons are pushed. Has anyone managed to fix this problem? I'm thinking I'm going to have to take the infuse apart and see if the button is stuck or if there contact occuring somewhere it shouldn't be. Any help would be appreciated.
Yeah, i have this problem. First what i did, i'd hit gently the power button a few times and it seemed to work. But after a few days it got worse, till the point it wouldn't work. I decided to open up the phone myself, and trying to manipulate the small power button. Apparently it worked, but i decided not to use the power button anymore, i wake the phone by touching the volume +/- buttons and i turn it off with a widget i downloaded from the playstore. This problem seems to be on every infuse i'm saving up some money to buy another phone, since i won't be able to sell this one with this problem.

Here is a video of a screen replcement- not what you are doing but it shows you how to take the phone apart. Hope this helps.

Thanks for the link. I took it apart using that and cleaned everything and just clicked the power button a whole bunch and its working again for now.

It happens that to one of my infuse before and i send it so Josh @ http://mobiletechvideos.mybigcommerce.com/ he replaces my power buttons and services is amazing and shipping is fast.
I bought an used infuse the other day to fix and sell to a friend. The owner said it was bricked, but I've since gotten it into recovery mode, download mode, and a normal power on. It goes into a bootloop most of the time though, the endless bootloop people seem to be getting when the power button gets stuck.
I've completely disassembled the phone and I can't find the problem. The power button (the white one on the inside) moves completely freely. I've tried booting up the phone with the back housing off so the power button is bare but it still bootlooped. The only way I can get it to boot up is to repeatedly hit the back of the phone onto my hand as its booting up. Even then, the phone will only stay on for 30 seconds or so once it boots. I've read of people fixing this by simply throwing the phone on the ground, but is there a better way to fix this? What could be the problem?
Edit: I think I may try this: http://forum.xda-developers.com/showthread.php?t=2235435&highlight=bootloop
It could be a weak connection on the mobo somewhere.
Edit 2: Yep! I re-soldered the connection around the power button on the back of the motherboard and the phone is working. Got it reset and now I'm running it without the second power button thing in the case.
Hi,
I think I have bricked my S7.
Yesterday I installed Superman Rom and everything was working fine until this afternoon.
I played a bit around and somehow my S7 got stuck and it seemed like i messed something up. I was in some kind of bootloop so i flashed everything new -Bootlaoder, Modem and Superman Rom.
Now I have a black screen and the LED is light up in blue.
I can't do anything. Tried to restart with Home Vol- and Power key but it doesn't work.
If I connect it to the Computer it won't be recognized.
Strange thing is, if I press the Power Key the computer recognizes Exynos8890 in the device manager, but only if I keep pressing the power key.
As soon as I release the power key the computer recognizes nothing...
Does anyone have an idea?
Try holding Volume Down & Home & Power until the phone reboots twice, keep the buttons pressed for 2 full reboots, and hopefully the 2nd one will get you back into download mode
Thank you for your help!
I tried that but it doesn't work.
It's strange because I can do what I want and nothing happens.
Black screen and blue light. It doens't even turn off or reboot...
Only thing what happens is that exynos8890 appears in the device manager as long as I keep pressing the power button.
Same problem as me?

Sounds different.
Because you are able to get into recovery and download. I'm not able to do that

How long are you holding the button combination for?
Try 30 seconds+
I tried for several minutes, but the phone doesn't do anything.
I can only think you'll need to wait until the battery runs out, the phone shuts off, then when you charge it again, try the download mode button combo when you power it back on
Ok thank you.
I thought the same.
Unfortunately the battery was at 90% so I think it will take a few days/weeks until it dies...

Connect the white Micro > Normal USB adapter that came with the phone to the MicroUSB port, and connect a power hungry USB device to it, I just tried with a USB desk fan and the phone powered it on spinning
That will drain the battery quickly
Great idea but it doesn't seem to work.
Looks like I have no power in the USB connection.
Seems like the phone is totaly frozen.
Ok so how it looks at the moment, my only choiches are wait several days until the battery dies (don't know how long this will take) or sending it to Samsung for a repair.
Thank you for your help!
Good luck, if I think of anything else I'll reply here, hope you get it sorted
EDIT - Did you try holding the power button while you had the USB device connected, to see if it provides USB power then?
Wow, the exact same thing literally happened to me yesterday.
I wasn't doing anything to the phone - it's completely stock and unrooted, and I wasn't messing with anything. At the time it happened, I scrolling through the task switcher when all of the screenshots of running apps suddenly became white squares. I tried pressing the home button but it didn't respond (though I could still scroll fluidly through the white squares). A few seconds later the screen went black and that was it. Dead dead dead. Totally bricked. The only response I can get is "Exynos8890" in the Device Manager when holding the power button, just like you.
This really sucks because I paid full cash and imported an international version, so I have no warranty. I'm off to the Samsung store to plead with them about honoring the warranty anyway, maybe if I offer some cash on top.
I suspect the storage chip failed. Yesterday before it died, I was downloading all of my images off of the SD card to organize them, and I noticed that about 5% of them failed to copy due to an unknown I/O error. Of course I assumed this was a corrupt SD card, not internal storage. I did manage to pull them all off (though some were damaged) through a combination of adb shell, dd, and adb pull. During the process the phone hard-locked a few times, but each time I was able to reboot via the VolDown+Power combo.
When the phone finally died for good, it was several hours after I had finished copying the photos and since hte last reboot. It had been working perfectly since then - I was browsing reddit, watching netflix, etc. However, given that I got the white squares in the task switcher right before it kicked the bucket, I think the internal storage was actually to blame, not the SD card. The white squares indicates that it was trying to fetch the screenshots off the disk and failing.
It's very odd that I cannot find any other instance of this kind of failure on the internet except this one thread, which happened on the exact same day that my phone died. Very strange.

That sounds exactly like my Problem.
A faulty storage chip would also explain my Problems before the phone died for good.
The day my phone died I had some Problems. The phone was frozen from time to time until it got into the bootloop, but I thought I messed something up in the Rom because I did a lot of testing and the Combo also did work.
After reflashing the Rom everything seemed to be fine first until it died for good.
Yes it's strange, I also didn't find anything similar on the Internet.
I have learned my phone is from Nigeria. This should be a fun RMA process. FML

Contact Samsung on twitter, unlikely they'll force you to RMA to Nigeria, they'll have service centres in your region
I managed to get Samsung Canada to refer me to a local service center. I drove 1.5 hours to go there today, the dude plugs it into a charger, and the damn thing just lights up like nothing ever happened. Now it's working fine, but I swear this thing was fully bricked before. The battery still had 73% charge when it came back alive...
I'm happy it's working now, but I'm worried it's just going to crap out again at any time.
Update: after the phone revived itself, it worked pretty well for a week. It locked up a few times, but I was able to reboot each time.
But, after a week, it hard-froze again. This time, it happened to be on charge while it froze so the green LED was on. It's been completely unresponsive for 2.5 weeks now, off charger, with the green LED on. I keep waiting for the LED to drain the battery, but it's taking forever. I'm losing hope that it will recover this time. I guess I'll re-start the process of getting in touch with Samsung, or alternatively, look for a replacement motherboard on eBay.
Does anyone know if the G930F motherboard fits into the G930FD body? I don't actually care about dual sim, but I'm concerned the SIM tray/slot won't work with the G930F motherboard.
Update:
so in the meantime the battery of my s7 died but that didn't change anything. I wasn't able to charge it after that so now it was completely dead.
So I contacted Sasmsung.
They replaced the motherboard and the USB connector on warranty.
Seems like it really was a hardware issue...

Hi,
Do you need Proof of Purchase for the warranty?
Thanks.
