So here's the gist. My s4 has been rooted for a while and very recently while removing some apps and bloatware I decided to remove the "Help" app since it seemed useless. I think I messed my phone up by doing that because by then my s4 would randomly give me the black screen of death or get stuck in a boot loop. To fix these problems I would take out the battery and hold the power button for a minute, or clear cache from the boot loader menu or reboot in safe mode which would inexplicably fix my phone normally for some reason. But all these options only temporarily fixed my phone and it would just continue with the same problems (Boot loop, black screen of death, etc).
I eventually resorted to factory resetting my phone, all though not the conventional way At first I tried decrypting my s4 but my stupid usb cord stopped being recognized by my pc and that screwed up the decryption so my phone factory resetted itself on it's own pretty much. Now I'm having trouble getting to the boot loading screen but I can get to the download/odin screen.
I looked up online and different guides told me the last resort is to do something called an emergency firmware recovery. I looked up on youtube what to do, tried using Kies but Kies said it doesn't support the s4. I then tried using Smart Switch but when I get to the screen where it tells me to enter my serial number, I enter it and it tells me that I'm entering the wrong serial number, even though I triple checked what it is! I google searched if other people were having this problem with smart switch and other people are having similar problems as I am. I'm running out of ideas on how to save my phone. I don't think it's a hardware problem because I haven't dropped my phone very recently. Does anyone have any ideas on what I can do next?

I have an unlocked HSPA+ Galaxy Nexus imported from the UK to the US. Ordered from Negri Electronics.
It's not rooted or modded in any way.. Mainly because I don't know how to. As far as I know, it's running stock ICS.
I was using it normally, (using the fb messenger app if it makes any difference) when it suddenly rebooted by itself. The Google logo comes up, then the start up animation, and sometimes the home screen will appear but is not touch sensitive (i cannot slide it to unlock), and then it 'hangs' and the screen goes black. Repeat.
I've tried to fix this by myself and there's a video on youtube (sorry, noob here. can't post links. video is by robbidwv and title is "my galaxy nexus won't boot..") of the same problem that I have, but the posted solution doesn't work for me.
So far, I have entered Coin Mode and pressed Start. Entered Fastboot mode and gone into Recovery Mode (no options appear after that. it just starts booting up and the loop begins), and I've also tried Restart Bootloader.
I've almost given up. Now all I want is to extract my SMS, if they're still on my phone. I can't access the folders on my computer because it won't boot up and connect. Is there a way that I can extract my SMS by using DOS in either Coin Mode or Fastboot mode?
Or even better, does anyone have a solution to this boot loop problem? I'll contact Negri Electronics tomorrow and hopefully they can send me a replacement.
Please help!! Thanks
that problem just started happening with me an hour ago!!
i hate this!!
we need a solution please!
Hey guys, sorry about the issue.the major problem I see here is you wanting to retrieve your txt messages, which might be possible with a little Modding, but if yourwilling to lose them to get a working phone back, then this is what your going to have to do. Make sure your phone is completely off. Hold the 2 volume buttons and the power button together. You will get into a mode with an android Guy. Press the volume button up or down until it says reboot recovery at the top. Press the power button. It will rebootand come to a screen with an android. Hold volume up,down and power at the same time. A menu will come up. Go down to wipe data. Click it, and after it is done reboot. Your phone should work now.
If this helped you, or you simply appreciate me taking the time to write this out then please press the thanks button
Hey!
Thanks. Yeah I 'fixed' it already. I was just about to post something similar. After a while I just gave up on trying to recover my data. Good thing that Google syncs everything so the only issue would be recovering my messages, which I decided weren't worth sending it in for a repair which would probably not be able to recover anything anyway.
The thing I didn't know about was to press power + volume up WHILE on the recovery screen. I thought navigating to the recovery screen was it!
Still, this kind of sucks. I love my GNex, but I can't help but be slightly pissed seeing that my crappy iPhone 3GS never did this in the 2 years I had it. Oh well, hope it doesn't happen again!
hey guys! i also did a complete wipe on my phone and got it working again!
but i wonder why this happened in the first place?
last application i installed before the crash was double twist, i dunno why but i feel that it was the reason behind the boot loop!
Sorry for reviving this thread, but I just had this happen to me TWICE!
It happened to me first last Monday, the 23rd - the phone crashed when trying to send an email with an attachment - and went into a boot loop - Google logo would appear, no make it to the animation, and reboot....
I performed a full reset and things worked again. I didn't install all the apps I had before - figuring it must have been due to some app messing with the OS.
Well, it happened again to me yesterday! I was connecting to my bluetooth headset when the phone crashed and went into the boot loop. Full reset worked again, and I've installed even fewer apps - essentially only those that I use on a daily basis.
My phone is still on 4.0.1 and I'm hoping once 4.0.4 is pushed this may get resolved? I have a canadian GNex from Negri. I will call them again (I called the first time, but when the full reset worked I never contacted them again).
I would like to this this is a software issues, and not hardware.
I have the same problem. If you figure it out let me know.
Today my phone also entered a boot loop: [Google logo]->[black screen]->[vibration]->[Repeat]
I tried Recovery Mode, but this is what happens: (sorry for the link but I am not trusted with powerful tools such as outside links apparently, as I have not yet reached the maturity of a person with eight posts... )
dl(dot)dropbox(dot)com/u/53568097/Android.jpg
This is what I see when I navigate to Recovery Mode
For a split second I can see an image of an Android with spinning cogs in his innards, but then this little sad fellow appears. WTF is this?
EDIT:
Oh, and I'm running Android stock 4.0.2, never rooted or unlocked, Swedish. At the time when the phone started doing this, I was using Endomondo, and was about to set off on my bike when it died on me.
Stock ROM galaxy nexus bootlooping after wiping data also.
Hi,
My GNex went into a bootloop so i searched xda and found that factory reseting would be helping my prob. But after wiping the data also its still in going through the loop . Please help .:crying:
Somehow I have managed a binary count of 4, and I need to reset it to 0. For some reason my phone gets to the screen where it says "4G lte" with all of the rings expanding and stops, it doesn't boot any further, it just sits at that screen forever in a loop (I feel like this could be due to the binary count?). But anyways, since I don't have access to my phone I cannot use Triangle Away, so I was wondering if someone could please tell me how to reset it from the computer or in download mode. Thanks!

While I can't answer your specific questions in regard to the count..
It might be worth it to hook up to a PC with the USB cable and check out the logcat. Typically in a boot loop it'll be trying to do the same steps (and failing..) over and over again. Might be some very useful information there and the problem could be totally unrelated to what you suspect it is.
Another super ez option would be to simply restore your last known working nandroid backup..

Unfortunately I do not know how to use the logcat what-so-ever, so I wouldn't know what to look for, the loop only begins when it gets to the verizon rings, it's not restart the whole bootup, it just gets stuck at the last boot animation and never displays the homescreen, if I am making sense
As for restoring the most recent nandroid, my phone for some reason will also not boot into recovery mode, I can hold Volume Up+Power+Home to attempt it and it will show the Samsung Screen and the "Recovery Booting..." in the top corner, but the recovery mode never actually comes up, I just have to let go and then it restarts itself normally and gets up to the Verizon animation and loops there
Hello all,
Hoping you might be able to help me troubleshoot a family member's dead S6. He took it in to Sprint a couple of days ago with some issues, and got it back from them the next day claiming they detected water damage. No warranty on the phone, and to make things worse it's a rental. The phone turned on before being brought in and was just sluggish and chugged out sometimes, and now will only go through the Samsung logo and hang immediately after on every boot attempt. From what I've been told, the phone's never been dropped in any liquid, so I'm not sure where the water damage claim may have come from.
Either way, I've been trying to see if I can do something about it. Here's what I've tried so far (in order), to no avail:
Hard reset: Since phone hangs after the initial splash screen, I have to enter download mode, restart, and then hold the proper keys then. I am able to wipe all data/factory reset, but nothing changes.
Let battery drain down completely, charge, start phone. It actually managed to boot part-way, and hung up on "Updating Applications" screen. Subsequent restart attempts led back to black screen.
Reflash: Phone boots successfully into download mode, and I am able to flash firmware for G920P. May be important to note that the two times I tried 5.0.2 with PDA G920PVPU1AOCF, I got a FAIL in ODIN at NAND Write, but was able to successfuly flash 5.1.1 with PDA G920PVPU3BOL1.
Still not sure if I am able to distinguish a hardware issue. I would highly appreciate it if someone here can help or suggest further troubleshooting steps!
Bump?
Greetings!! before anything else, my english is pretty basic so apologies for murdering the language.
This morning i found my very old and beloved Samsung Galaxy Core 2 G355M turned off, i thought the battery depleted during night for leaving some app open like steam or chrome, anyway this happened so many times in the past so i just plugged the phone to charger, turned on and it was stuck on "samsung" screen for more than 2-3 minuteS, that was very unusual and it never happened before so i restarted hoping it was just some random malfunction but nope, the phone still stuck in that samsung screen.
I removed the battery and that didn't fixed it, neither removing the SIM card/chip and/or MicroSD.
I watched some videos (and dozens of websites) about the "hard reset" method pressing and holding home button, power button and volume up button... let me show you exactly what i mean with a couple of videos in spanish, the model they have is the exact same as mine the G355M.
then, what's the problem? well when i do it, my phone shows the green android robot with a red warning sign and then it just restarts, no matter how many times i've tried, soon as the little android guy shows up, the phone restarts, it doesn't show the "android system recovery options" like you can see in the videos above.
BUT WAIT!!! i kept trying and sometimes android succesfully loads (no system recovery tho) and then im at phone initial configuration options, you know, with some "welcome" screen, when it asks for your name, google account, samsung account, wi-fi connection and all that stuff you must fill with a brand new device. I thought the "hard reset" worked somehow but nope, now the next problem is that several android and google services crash while doing this "initial configuration" and sometimes the phone restarts itself and if it doesn't i can't continue because those "services" were crucial and the phone stays in some infinite loop trying to validate either wi-fi connection, google account or my name.
What do you thing happened with this phone? it was working just fine last night, i woke up and saw it was turned off then this permanent "samsung" screen.
Is there any PC software that can access the internal memory or fix the entire phone? maybe i can save some old SMS messages or stuff stored there which now is locked or deleted (coz i did this "hard reset?")
I know nothing about flashing, odin3 and that sort of stuff but im very familiar with PC stuff so i guess thats the only thing lef to do, mess around with the phone, there's too much info around so id appreaciate if you guys point me in the right direction (odin3 tutorial, trusty websites with firmwares, roms and that stuff for ancient samsung devices). Meanwhile gonna read everything about odin and how to flash, thx in advance.
BTW this user had almost the same problem like me...
Samsung Galaxy Core 2 (SM-G355M) - Recovery mode does not work.
Helo! I'm new here at FORUM. In a desperate attempt I decided to create an account here and try to solve my problem with a Samsung device. It all started when I received a Samsung Galaxy Core 2 device to fix. It is stuck on the Samsung screen...
forum.xda-developers.com
The problem I have is with the galaxy z flip 3, it worked just fine inthe morning but after it ran outta juice and I charged it to a certain percentage, it stopped working properly, and got into an infinite boot loop, I tried forcing it to restart by long pressing volume down+power , but it didn't work, then I tried opening the recovery by long pressing on volume up+power and yet it also didn't work (I think that maybe it's because it was trying to boot at the time), so have you guys any solutions , please do help me cuz this phone really is important and with all honestly, isn't even mine XD, I'll be waiting for an answer
Your failsafe options are contact Samsung or do a factory reset (and then potentially contact Samsung).
If you can't boot it to anything, the only real option you have is to flash firmware, which likely won't help without wiping.
Unfortunately, not booting doesn't have a whole lot of options that don't wipe data without being rooted. Even then, you'd need recovery.
I see, then I may consider giving it to samsung, as long as they won't reset it, cuz the only reason why the phone is so important is because of the data, altough, isn't there any other way to acess recovery? Cuz I had this problem with the s10 before and I fixed it somehow (a certain Bixby key combination), but this time it seems there isn't any hidden combination.
Samsung is going to reset it. It's a required first step for them to do any work on it, even if the work has nothing to do with the software. What may help find a way to recover the data is starting with how it got to this point. Did you install anything new, change any important settings, or anything else that could have been a part of the issue? If not and it is an unexplained hardware failure, the data is likely gone already.
If it's something you might have installed or changed, it's possible that putting the phone in safe mode and undoing it may solve the issue and let you boot normally.
Booting into Safe Mode:
Make sure the device is powered off (charging is ok, as long as it is not currently trying to boot)
Hold the side key to power on and continue holding until "SAMSUNG" appears and the device vibrates
Immediately release the side key and begin holding volume down until boot completes
If the device has booted into safe mode, you will see a translucent "Safe Mode" in the bottom left

Well I just asked the original owner (my mother), and apparently she doesn't remember downloading anything new into it, and it just went crazy by itself, also something else I wanna note, I tried charging it and it booted into recovery all by itself, I taught it was weird but Still went and wiped the cache and then when I tried restarting it it suddenly ran out of juice once again, also, it's second display shows some weird curruption/bug or glitch-like lines. So based off of this, can you really find the origin of this problem and if there is really any hope of saving it's data XD. Thank you btw, and once again, I'll be waiting for an answer
There are hundreds of reasons it could do that, including a faulty board. Thanks to the removal of physical sdcard support, you'd need to get it to boot into something with at least adb support to pull anything off it. Stock recovery doesn't provide any ways to perform a decent backup, but it sounds like the only option that wouldn't wipe the device didn't work.
I see, alright, thanks a lot, I'll consider resetting it
It may be worth trying to flash firmware first. Go into it knowing it may reset the device or leave you needing to reset it, but it doesn't hurt to try if you run out of safer options.
Same here, same symptoms, happened in front of my wife's and eyes face. We are fairly techy and understand our way around our devices. We also noticed the device crashed then would make it all the way to the home screen launcher and before catching signal the crash would cause a restart at that point I went in and did a cash swipe rebooted right back into recovery by itself then I unplugged the cable and it was acting as if it has a dead battery but when the cable was last plugged in during a couple of crash and then restarts all the way to the home screen I know the battery was at 70 something percent. My next step is going to probably be flashed the current firmware that just released on top of it as a dirty flash and see if I can get it to boot. If not then I'm going to do a hard reset and see if that works. When plugged in it automatically starts exhibiting symptoms as if the buttons are stuck. The devices in the OtterBox and it's fairly brand new I would say mint. Not dirty or any smudges either. all I'm saying is I'm one of those type of technicians that say yeah right when people say it just happened I don't know where but this actually happened I don't know when I was able to witness it. I'll come back and let you guys know what works and what doesn't. (By the way excuse my grammar I was voice typing while driving )

Hello everyone just a quick update. Once I got home I plugged the device into a Samsung fast charger and Samsung OEM USB type-c cable and realize the device booted all the way to the home screen but register the same battery level as I mentioned above. Device was working as if nothing happened to it. So I updated all the apps on the Galaxy store then updated all the apps left over from the Google Play store, I then proceeded to check for a firmware update because I know the April update just released and installed the update with no issues. Updated the apps that needed to be updated again somehow there's always something and unplug the device from the power cable. Everything was working if no issues about half hour later the device cuts off and does not want to power on. FYI I already had my wife contact T-Mobile and get a warranty replacement we only paid $5.00 so my thoughts and conclusion on what's going on something happened to the battery or it's defective. Btw we only use Samsung OEM cables and equipment at home and in the car while connected through Android auto. it's only working while being plugged in it's not charging all the way even though it's registering it's charge level while the device is on.
