Bootloop: safe mode and download mode not working - Samsung Galaxy A10 Questions & Answers

So, my Samsung Galaxy A10 got into a bootloop and I'm 90% sure it was caused by short storage, because seconds before it started I saw the storage was full. I've had a similar problem before, where my phone would randomly reboot and stop when I clean up some space, but now it just locks itself on a bootloop and freezes on the Samsung logo.
I tried entering Safe Mode, but my phone just won't load it no matter how many times and how many buttons i press. Alright, "let's try Recovery Mode", i thought, but it was also very hard to do because the buttons wouldn't work most of the time. I managed to enter it around 4 times in a span of 3 hours and I got two different screens. One screen was what I believe to be the standart, with options to clear cache, factory reset and etc. The other one only had the option to clear app data, no idea why it changed or what triggered it. In these few instances where i could access the Recovery Mode, I tried clearing cache, repairing apps and clearing app data, but nothing worked.
I can't turn off my phone either, I tried holding the power button for almost a minute with no results. Maybe that's why the recovery mode didn't work...? Right now I'm waiting for my phone to run out of battery and see if it helps.
Also, one thing that is kinda concerning... everytime it reboots, before the Android logo appears, the screen glitches for a millisecond in a vibrant color.
Please, is there any way to fix it without losing my data? I'm sort of a noob so I have no idea how bootloaders and similar things work, I'd be really thankful if you guys could help

Welcome to XDA
Meh... why isn't your data on a SD card?
If you used a SD card as a data drive... you be able to do a factory reset and not lose critical data.
If you can't connect with the PC and you can't get into safe mode I don't see how you can recover the data. Maybe someone here has a plan for you...

Thanks! Yeah, no SD card for me
Draining the power didn't help, but I figured out why the buttons didn't work: I was supposed to press them when my screen started glitching, not on the android logo (leaving this info here in case someone else has the same problem). Still unable to access safe mode tho, only recovery.
Welp, most of my data was only personal things and at least I can backup some stuff with my google account, so I did a factory reset. Now it's working again, which is great, I just wanted my phone back honestly :,)

Boot loops are tough. Sometimes after a couple tries it may go into safe mode but don't count on it. Another question is what caused it, a poorly coded or incompatible 3rd party app running at start up? You don't want a repeat. It may have been a single event upset that corrupted the user data partition, these are rare but can happen.
Get a SD card and use it as a data drive, everything you need to do a complete reload should be on it including installable copies of all your apps. A full reload with no internet connection can be done like this. Since all the data is already on it for a reload, no time is wasted reloading data.
The SD card is a valuable asset if you use it correctly.

[Q] Buggy Phone, Factory Reset, Now What to Do?

My 4G will be 2 years old in February. It is quite buggy now, it likes to lag a lot or glitch, it's definitely not the lightning machine that it used to be. I saved all of my data and am going to perform a wipe/factory reset and wipe the cache partition (hopefully I am allowed to do that, if not, oh well too late).
Is there something more potent then a factory data reset using the Android Recovery mode while not in the phone OS? It resets the phone but I have the latest OS, which I think could end up keeping all of my bugs. Can I go back to the original OS when the phone shipped and legitimately start over and re-update everything? I logged back in and an app widget was still there with writing on it, some of my pictures, and some icons I moved around. this is after I did a rest outside of the phone, then went in the phone and did another reset. So much for wiping all of my data I guess.
So, if this does not fix the buggyness of the phone, what should I do? The phone likes to press buttons randomly and I have to hit the power button to lock it, and then unlock it for the magic button pressing to stop. This is common. Apps are slow or time out a lot and it takes the phone FOREVER to reboot. It love to randomly restart, especially using pandora or spotify. It takes a long time to connect to Wifi, sometimes I have to go to the wifi settings to wait for it to automatically choose my saved network, which baffles me like crazy.I did have the most recent update of course. I think the finger print scanner also stopped working... or it never did work. Lastly, the vibrating unit doesnt always vibrate, it likes to vibrate on a few keystrokes and it randomly stops, then starts up again. **** this phone. It really makes me want to go to an iPhone... and I am a hardcore windows computer tech and I hate apple, but ****, why cant anyone build a stable OS?
So, assuming my phone works correctly, what should I do to it once it's up and running? I am ready to Root the phone and try some new apps and hacks and what not, especially if it makes the laptop dock mode faster, cause right now it's slow as ****.
Factory reset basically wipes the /data partition.
I would also recommend you do a format of the internal sd, after the factory reset (see storage in the system settings). This way, files on the sd will have no impact on apps as you reinstall things.
Regarding returning to an earlier Rom version, I would not recommend as being part of the solution. Newer Rom version are better usually. Gb by motto is solid.

Lumia 920 Sad Face

Did an update, came out with restart, then ATT boot logo, then Nokia boot logo, then gears for update, then ended up with a sad face.
Completely unresponsive, seems like a brick. Power and volume down restart it into the sad face once again.
There was very little space available, is that what may have caused it? Battery at 100%, etc.
What can I do now? Where can I find a backup?

No, storage is on a different partition.
Did you try a hard-reset ?

Hard reset as in wiping the phone? Does that erase everything, or just the phone partition? I see photos backed up to SkyDrive, is anything else backed up?

Sorry for late answer, hard reset will wipe all your data, reset it to factory settings.
If you have your pics uploaded to skydive they will not be affected.
If you have been backing up your device on a regular basis ( text messages, application list and contacts ) won't be lost as you will be able to restore from backup once reset is done.
Lumia 920 spinning gears and sad face
I need your help, I had this bad experience since a month.
I also had limited capacity like 1.5 GB or sometimes 750 MB.
One day when I was taking a photo, I noticed that the camera application closes after I capture the photo and the photo does not appear in my Photos Folder, but when I connected the mobile to my PC, I was able to view all photos.
After that it suddenly gave me black screen but I felt that it is still working.
Then the mobile was working again then it gave me the spinning gears ending with the sad face
since that day I could not open my mobile phone.
I tried charging it (battery) but the only thing I feel that the device gets hot.
I also tried to remove the sim card, but all in vain.
I have a lot of photos, screenshots and messages that are not backed up on my sky drive, does anybody know a solution without having to restore it t factory settings.
I heard that there are softwares that could help recover all your data even if device was formatted.
I appreciate your quick reply.
By the way I visited more than one Nokia Care in Egypt, they are such idiots

[Q] Android gets into a hotboot looping state for unknown reason

Hi.
My Galaxy S3 is frequently getting into hotboot looping state for no apparent reason. The only way to get it out of this state is to wipe the phone or restore a backup of the "data" folder only.
After that, it might work for a week, but it might not work for a day (not work = start to hotboot loop).
It happens when after the phone screen is locked, it doesn't wake up anymore. It doesn't answers to any calls (like if it's off) or notifications. Just dies.
Forcing a reboot (by holding the power button) or removing the battery ables me to reboot it, but enter in hotboot looping state. I can make it go thru the whole booting state and I see the homescreen (And that's weird because I'm supposed to see the lockscreen first). Some widgets animation works but the device doesn't answer to touch (two softbuttons vibrates when touched, they do vibrate but don't render anything on Android) and then hotboots. Keeps doing this forever. Booting into safemode USED to work, but it doesn't work anymore, I don't know why.
After wiping the device or restoring the Data backup, device turns on as expected (restoring data takes it back to working state exactly like it was before the backup, even the same lockscreen pattern). I've tried to leave a terminal running logcat to catch the error, but it doesn't write in realtime, so when the bug breaks out, the logfile is empty.
I even thought it could be the S3 memory issue with firmware, but I'm using the "fixed" kernels. Also, it is recoverable, and not permanently dead.
I suspect of some rogue app, but I have too many apps to just go through installing one by one (and waiting even weeks to install the other one). Is there any way I can get a postmortem logfile or make logcat write in realtime?
Thanks

Try flashing another ROM for S3 and doing a full wipe.

Thanks for the reply.
I already did. It started to happen out of nowhere while I used the Android Revolution HD ROM, then after a few wipes and reinstalls with the same problem, I gave a shot to WanamLite ROM. Exactly same problem. Both are based on the original 4.1.2 Android.
I'm pretty sure it is being caused by some rogue app, because the only thing in common between those ROMs is that I "batch-install" all my apps back from Google Play.
So far, I'm suspecting about Vine (it's the last install that I remember since it started to have this issue) and I have already uninstalled it, but it might have been caused by some app update that broke hell to my phone.
If there were some kind of "black box" that I could retrieve after a crash, it could be the solution

If you wipe data, your apps disappear, so I think this is not the problem.
Do another full wipe and DON'T restore your data. Just download again from Google Play and see if the problem appear again.

I started doing this the first time, but it still crashes it. And as I was wasting too much time with this, the backup option came as a option to not have to click to download over 200 apps one by one. Also, it once happened during a long holiday, and I was in a friend's ranch with no decent internet connection for downloading. All my apps were gone and I was stuck with a default phone for five days.
The backup is exactly the point where I finish downloading all the apps and they're installed. There are no cracked programs or adapted (e.g. Nexus camera). Every single app is obtainable from Play Store, so it's pretty fresh
Funny (actually sad) thing is that it's a system-wide error that a wipe solves it. If I don't wipe data and reinstall the same ROM (which under normal condition is no big deal), it doesn't get past from boot screen.
The worst is it happens instantly. It's working now, but then it crashes. Bam, gone. Few hours ago I was texting my gf and I left the phone for a while, waiting for her answer. After some time I knew something was off, picked up the phone and it was pretty warm (first signal), with the LED blinking some Facebook notification. Tried to wake up but it is in coma. I force a restart and it hotboot loops like I described on first post
It -only- happens when screen is locked. I disabled the screen lock for now to see if it's a workaround, but I'm not holding my breath
It could be a hardware malfunction if it can carry through all the roms you flashed and even when you tried a fresh install without your apps it still happened.

That's pretty much discarded. Wiping data instantly solves it. It did indeed run for 5 days with no external app without a single problem.
But also it ran over one week with external apps without a problem. I've executed some memory integrity tests and they all reported a-OK.
I'm kinda ruling out the "rogue-app" issue. I thought that recovering "data" from NAND backup was the /sdcard/android/data. But it's deeper than that. Now I don't even have a lead.
Phone already crashed today, without Vine and lockscreen, so that's not the problem. I really need to get some logs out of him. Just need to know how. Only if it could write a realtime log, so I could pull through ADB.
My last resort will be a fresh-fresh android installation, default S3 i9300 ROM, with only essential apps. Already have it triggered for the next crash.
If it goes rogue even this way, I'm running triangleaway and returning it (will be a profit too, the silver border is stripping).
This time around, I'm trying running it without a external sdcard (several files were being corrupted in it, don't know if it's due to force restart by removing battery, or some real issue on the card)
It's a problem within the Facebook social app or Youtube.
I've managed to run the phone flawlessly for weeks without signing in on Facebook, suspecting it might be it.
Today I logged in on Youtube app accidentally, and had to login on Facebook app to retrieve some info. Three hours later, phone went mad again.
I don't know which app caused it, but I think there's some relation to Facebook due to a greater ~involvement~ (couldn't find a proper word.. forgot it) with Android.
I've changed ROMs, launchers, system versions.. but not Kernel. I'll try another kernel and report on Boeffla main thread to see if there's some known bug

safe mode glitch.

My phone is stock and I am not interested in any mods.
The m9 has a lot of issues and I found another.
HTC told me to boot in safe mode to try to see if an app was causing issues. For the record, I get a screen black out when swipping away a screen or returning to home screen when first booted up. I reset twice and it's still there.
Anyway, I try safe mode out and when I boot back up, all of my apps seemed to have their data erased. All of my app placement customizations were gone and I started getting an error for LTE, which has never happened prior. It was a mess.
I factory reset again and it seems fine, appearing to be as it was before.
What was that glitch about? It was such an odd and incredibly bad thing to happen.

It is not a glitch, that's how safe mode works. It turns off all network connection, 3rd party apps and only loads necessary drivers. Similar to the way safe mode works on a computer. However Android can't recover data once it is lost after reboot.
So you're telling me safe mode is suppose to basically screw up your phone in order for you to see if maybe a third party app is a problem? That. Is. Crazy. It really defeats the purpose of any aid it could have.
It's a huge risk to take. I wonder why they'd design it this way. On the sprint forums, anyone who reported putting their phone in safe mode never mentioned any losses after. Maybe they didn't want to state them then?

Wait, are you referring to data that could have happened during safe mode? And once it was back to normal, it didn't save any new data? If so, that's not what I was talking about.
Literally all app data, even preexisting was gone and my phone set up was hugely altered.

Yes all app data is erased during safe mode that includes Sense Home which is you home screens setup. Android is setup that way because it loads only apps no data. Data is usually the cause of issues. If everything works fine in Safe Mode mostly the issue is the apps data. It is an Android thing and not phone specific.

LG Optimus F6 Possible reset?

Hi this is my first thread and also an emergency but any help much appreciated!
My Optimus F6 had this problem every few months but it usually fixes itself, where it gets caught in a boot loop and the MetroPCS logo would keep repeating on startup without going to home screen. The last time it happened a couple months ago it was also shutting down really fast without me doing anythingwhen it did work , so it most likely thought power was being held when it wasn't. I fixed it be blowing into the buttons and pressing them while the phone was off. I also removed the battery/sim card a lot.
Anyway today it went into the boot loop again...so I held the volume keys and the home button before turning it on, and it went into what I assumed was the recovery menu. Now this couldnt have been more than a couple seconds, but I was looked at the choices, and then it acted if I had pressed a key...and then it said "Error" unable to something something...regardless though I pulled out the battery immediately, this all happened very quickly. Now the phone boots fine but I'm getting the startup wizard as if it had reset. Now when I try the Recovery Menu again the choices seem normal now, so I maybe accessed a different menu before. I called LG and no help, I really need to know if the phone has been reset or not?
I have to go to work in a couple days and the thought of all my critical data being lost and my contacts and photos and memos on internal memory gone is gonna be really bad, I have no way to get some of the stuff back. Please help! Thank you!

Why don't you go through the start up wizard without logging in to anything and see? If it has been reset, I hope you had it set to back up your data to Google or some other cloud service or you're out of luck if it was not saved on an external SD card.
I would but I'm afraid if I go further through the Startup Wizard it'll further erase and chance I have of getting my data

It's either gone or not already. Going through the Startup Wizard has no effect on that.
