[Q] Galaxy Nexus Boot Loop (stock)

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... )

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:

L80+ Bello D331 (android ver. 4.4.2) stuck on "Just a sec..." loading screen

L80+ Bello D331 (android ver. 4.4.2) stuck on "Just a sec..." loading screen
Hello, I'm new to the community! :good:
I like to mess around with my old phones and LG Bello wasn't an exception. In this case what I did was root it using KingRoot, only to years later remove KingRoot (therefore root) from the phone. Afterwards I did a factory reset and now I'm stuck with the problem stated in the title-- after setting up my Google account the "Just a sec..." screen will pop up and it'll stay that way. I can go back to the previous settings before the "Just a sec..." screen but that's about it, it still won't let me access the phone's actual content.
I've done factory resets with this phone several times without any issues and I'm really confused on what the problem here is, but I'm assuming it's something to do with root being removed. I would try using PC to reinstall the corresponding ROM but there's another issue which is entirely my fault: the phone's volume buttons won't function anymore because I dropped it forever ago, therefore there is no way for me to access recovery mode (which normally would be accessed via pressing down the power button + the volume down button).
Pretty much what I want to know is if there is any way to salvage the phone at this point. If there isn't I don't really mind as, again, this is an old phone I didn't really use for much. But it'd still suck if there is absolutely no way for me to get it fixed.
Thank you in advance! ​

I've got solutions for you:
1) You could replace the power, volume up down buttons by ordering a replacement part online (ebay, i'm not sure if amazon is selling it, ifixit etc.)
2) You can continue without the Google acc and then go to Chrome without logging in and install the KingRoot APK.

SS RDX mode

Question from pure novice,
I was factory resetting my inherited Galaxy S20 phone, and got an unwanted screen not the screen expected , I can not get into the factory reset screen, can anyone assist
i let the battery deplete and attempted the factory reset and was successful but.... it still wants my sisters password or google account password , I might as well go ahead and root the phone
Did you fix it? I can point you towards an easy to use service thats cheap and I'm not promoting anything it's just what I use if I don't want to spend a day getting in to a phone. it's a guy I've used a few times from ebay and he's prompt and gets it done quick. Otherwise the ways I know how to do it might not work on that phone since it's newer but I know of a program that might open the browser and then from the browser you download a launcher app to get in the phone but will have limited access to a lot but can then download an app that might fix it.
I have a Samsung Galaxy S10 Plus that keeps shutting off and going to straight to SS RDX reboot screen. When I hold down the volume down and power buttons at the same time for 3 seconds it restarts back up fine but this happens frequently where it will shut off at a random time and restart back up again. Does anyone know how to completely stop this from happening to my phone please? I just finally unlocked this phone and switched carriers and now I can't even use my phone without having to worry when it will shut off on me again.

Samsung Galaxy Core 2 G355M stuck on "samsung" screen

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...

Hello,
My wife's Sony Xperia XZ2 Compact with model number H8324 has an issue with booting or maybe the launcher getting stuck in a loop after getting to the lock screen for a split second.
The phone seems to boot like normal and gets to the lock screen, we are even able to punch in one or two digits of the 4 digit pass code. Then it goes into a loop of the notification bar and back button flickering. From then on the phone is not responding except for the power button which brings up the normal "Turn off, Reboot, and Lockdown" menu. The issue just started out of nowhere yesterday morning and we haven't been able to fix it yet. We haven't done any rooting or custom rom flashing, it's running the official Sony software but it's out of warranty.
Here's a video showing the issue. The video shows the whole boot process but the link takes you to the last part after the logos.
We would love to get some files off it so if there is a way anyone can help us with that we'd prefer it over a hard reset.
Things we've already tried
Turning the phone off and on again
Unlocking the phone in the split second the lock screen works, this is just too short to swipe up and then put in four digits.
Rebooting the phone
Booting while charging
Booting into safe mode (this has the same issue)
Connecting the phone with USB to a pc, the phone is recognized by Windows, but it doesn't share it's filesystem with Windows.
Connecting the ADB to it, alas usb debugging is not yet enabled on the phone
Trying to get into recovery mode, we haven't been able to get into the recovery menu. Googling seems to indicate it might be holding volume up + power button when the phone is off but then it doesn't seem to do anything at all.
We're currently trying to run out the battery of the phone to see if that will resolve the issue on it's own.
If anyone has any idea, we would love to hear it.

I think u just need to reinstall rom file with newflasher and stock rom , did u tried it ? with newflasher newest version , u still can keep the personal files and flash stock rom for the phone , then i think this phone will run normal again
If u dont know how to do that , reply comment here , but u should turn off the phone to keep battery well , if u can't turn off the phone , try to press and hold volume up button + power button within 5 sec , phone will vibrate 3 times and totally off
Is there a way to get a stock recovery if somehow the recovery has been deleted?
