Unable to Boot error, but device works!

Greetings people!
Yesterday I got this message while booting up my TP (latest official ROM):
"The device is unable to boot because either you have turned off the device incorrectly or tried to install an application from untrusted source. Press END to reset your device or press any other button to cancel. This operation will delete all your personal data and restore the device to its factory default settings"
However apart from that message, phone works flawlessly without any noticable change in speed or stability! The only apparent problem is that it takes a while longer (about 10 seconds) to boot up because of that message. I tried a couple of backups, problem was solved at first, but returned later...
I do take daily backups, but since I hardly monitor my phone when I reset it, this problem could have been caused by an app or reg entry a while ago... and searching for the appropriate backup will be a pain in the ass.
Since there's no change in speed or stability, do you think it would be wise to keep using the phone as is, or is it possible this would cause further problems down the road?
Any other way to troubleshoot it (at least to find the program that's causing this) other than a hard reset?
Edit: couldn't wait so I reverted to a week-old backup, installed back most of my applications, and it seems to be fixed (for now)

Update! I just tried a new SD to try XDAndroid, and guess what, the error disappeared!
So there must be a program I had installed in the storage card, possibly trying to start a service or something on every reset... and failing.
Is there a way to troubleshoot this? Maybe through SKTools or anything similar? I have a ton of apps installed into storage card and it will be a pain in the back cover to try by trial-and-error.
Thank you in advance
edit: inserted my old storage card again, error did not appear, problem solved! At least for now
Still if anyone knows how to troubleshoot this, please let me know

Update: Seems this error occurs every time I use SPB backup.
Yesterday, after a scheduled backup, the error came back. To troubleshoot this, I removed the SD card, did a soft reset, the error was gone! I took another manual backup, and again, the error came back.
So there must be something happening with SPB Backup and my SD card. Probably messing with files on the SD, or the driver or whatever (no idea there, I'm a total noob when it comes to software).
Moved the issue to the SPB forum

I have this message to, but I have never used SPB Backup

Well, in my case, it was obviously something tampering with the SD card (even if not SPB backup, something else)
Have you tried rebooting your phone with the SD card taken off? I just wait till it boots normally, and then insert it back. Works for me every time.
If that still happens, that probably means whatever is causing the problem is in your main memory.

Well I tried that just to see what would happen and I did not get the error message. So it is something on the SD card, but booting without it is not an option for me as I have several boot-start apps that are housed on it.

Perhaps one of those apps is broken?
As far as my case goes, I kept on using it for three months after the error appeared, without noticing any lag or issues at all. The only downside was that it took me three minutes to boot up, something I got used to.
If that's no big deal for you, I'd suggest you just leave it as it is for now, and check for lagging or specific applications failing (maybe one of them will be the app that's causing the problem?). If nothing happens down the road I think it could be safe to leave it as it is.
Now, if you can't stand this, I guess the only practical solution would be a hard reset. You can always play around with removing/reinstalling those apps you mention (or even better, installing them in the phone's memory) to check if and which one is broken, but I can understand that this not only will be a huge burden, but you may come to the conclusion that no specific app is causing this and something went south in the OS.
Personally the only apps which include a boot-up service I have installed into my SD are Football Monitor and PocketWeather. I tried removing both of them them back when I first had that issue, it didn't work...
Sorry I couldn't help more :/

[Q] LGL45C factory reset problems

Hi all, I come to you all in this time of great need. I have in my possession a LG Optimus Net or LGL45C as its know technically.
I started to suffer from problems from gapps resulting from uninstalling the Google Talk app(yes doing this in retrospect was incredibly stupid). After failing to resolve my problem when trying to re-install it, I decided to take the easy way and just do a factory reset and start from scratch. Little did I know what was to meet me. I was given the "Touch to the android to begin" screen like so many others, but it was not meant to be that simple. I would touch the android, and it would light gleefully but it would not reveal to me the next step and sit there motionless. So I proceeded to the next logical step, touching each corner in succession to skip the setup process. But no matter how many times I repeated it, nothing came of it. Next I booted into recovery mode(stock I never bothered to install CWM, another one of my mistakes) and did another factory reset, clear cache, etc. This too did not work. And I thought, there was always installing CWM through ADB where then I can then just flash to a stock ROM I downloaded. But Alas!! USB debugging some how got disabled and it was all fruitless. A little google-fu later I came across a method to flash .kdz using obscure LG utilities. With renewed hope I followed the steps but to no avail. Now I come to you stranger, and plead you in somehow help me in recovering some use of this phone. I have exhausted all my options and I hope someone out there read this and comes in my time of need. Sorry for the long block of text :silly::silly::silly::silly:

Having the same problem as you, bookface.
I couldn't install CWM from the links provided in another post, all lead to a 404 Dropbox page. This sucks. And when I tried to use the installer from Play, I got a dialog saying it's not compatible. Some would say to ignore it, it would be fine...
But if something doesn't feel right, don't do it, I've always been told...
So, I was rooted, but phone started acting funny. Done a factory reset. Since I didn't have CWM, I thought it would clear that mess up.
Nope, almost all apps crash. I'm lucky that at least the browser, Gmail, and music apps work, but everything else, including Google Play Store, all crash upon launch.
Net10's forum is a lame excuse as a "forum." Seems like TracFone employees have NO concept of how a forum works. I looked at there for the same issue, and they rather take software/hardware issues to private messages?
I have NO computer, my hubby's friend who helps him says "You have an Android tablet, that is a computer!" Technically, yes and no. Since I can't root that thing, it's useless. (If you want to know, Polaroid PMID709 4.1 with Rockchip RK29xx, and impossible to root fully, it's "semi-rooted".)
And I'm lost. I and my hubby need this phone to work. Because we need it fpr work (our jobs). And I'm getting sick of TracFone screwing up Android ROMs.
Please help!

youve made much more headway than i. trying to help my neighbor with his. he set a lockscreen password on his lgl34c and then promptly forgot it.
so upon a bit of research, this model is a doozie to work with. i had intended to overdeliver by flashing him a ROM that might allow some hotspotting and the like. upon closer inspection, i dont believe that i will be able to do that. at best a towelroot...
but ONLY IF i can get past this lockscreen. i've tried to factory reset by:
1) removing/replacing battery then holding vol down+power and waiting for LG splashscreen then releasing power (still holding vol down ) and then re-pressing(holding) power again
2) turning phone off and holding home+vol up+power and holding 30-40 sec
ive repeated both methods many many times, and these are the only methods that i have seen described in my google searching. in fact, yours is the most advanced post i have found yet.
how can i factory reset this phone without access to the settings menu?

[Completed] I think I bricked my ASUS Zenfone 2... PLEASE HELP

Stupid of me to do knowing the risk but I rooted my ASUS Zenfone 2 and everything was fine until I started playing around with an app called "LuckyPatcher". I was attempting to learn a few things about Android Rooting and all the things you can do with it. So I attempted to install an alternate Play Store and something must have went wrong because the actual Play Store was uninstalled from the phone and the alternate one was not put up in it's place... then after that I was getting a system message that read "com.google.process.gapps" and each time I hit OK to dismiss the message it would just pop right back up and would not go away. I tried clearing the Play Services Cache, Download Manager Cache and all of that but to no success, I was forced to restore my phone to factory settings but that's where things got worse...
After restoring it to factory settings, I was unable to get past the initial set up and the same message reading "com.google.process.gapps" continued to pop up again and again. I went on to try and go into recovery mode on the phone and when I did, the little Android guy would pop up for a second then instead of continuing the recovery process it just read "error" with the little Android guy laying on his side... I believe my phone is bricked and I can't figure out how to fix it and I would rather not reach out to ASUS about the problem, anyone have any Ideas? Anything would be greatly appreciated.
Thanks!

Xda does not condone, discuss or support issues due to warez. Which is what lucky Patcher is.
This is a development site, and stealing from them is not acceptable here.
You'll need to find help elsewhere with that. :good:

Weird stuff happening on phone

Hi all, my mom has an Motorola Moto G3 phone. Have noticed many weird things happening on the phone since yesterday.
The notification panel won't slide down. Also, no notifications are displayed in the notification bar, even when there are notifications, like receiving sms or messages on Whatsapp.
The phone has a swipe lock screen. But, the lock screen won't work, even though it shows in Security settings, that there is one.
Calls are being made from the phone, but no calls are being received. For example, if I call the phone, it says that the person is busy and the connection ends. My brother had also tried calling... same thing.
No apps can be downloaded or updated from the Play Store.
I tried to connect the phone to the PC, but, since I cannot slide down the notification panel, there is no way to change the connection mode to transfer data.
I should mention that the storage on the phone was getting close to being filled, and the phone was showing the warning that storage was less and that some of the functions might stop working. So, are these things because of that?
But, I did delete a lot of photos and videos and uninstalled apps, and now there is sufficient storage for the phone to run properly, but it still doesnt work, and these weird stuff are happening.
I suspect from the weird behavior that there might be a virus. Is that so?
What do I do? How will the phone return to sanity? How do I backup the data... if the solution is to factory reset the phone. There are important photos and videos and whatsapp data which I would like to save before performing a reset.
Any help will be appreciated.

A lot to cover there.
First Long press the power button whilst the phone is on.This will reboot to Safemode.See if you can now use a USB Data cable to backup what you need to your PC/Laptop/Tablet.
Note:Some USB cables are,"Charge Only" so check the USB cable is Data transfer capable.
Then if you have a Google account and are connected via Phone data or WiFi go Settings/Accounts/Google and untick and re-tick all sync options to make sure all your Google stuff is updated.
Then do a,"Hard Reset/Factory Restore.
Just put Moto G3 into youtube with the words Hard Reset,
https://www.youtube.com
Although a Hard reset seems like a big move I do one at least a couple of times a year as a kind of 10,000 mile service for my Android phones even if they are running well and it clears out all the junk I tend to accumulate and keeps them slick,fast and problem free.
HTH

Thanks a lot for your reply. Your post comes as a lifesaver.
I took a backup of the data by transferring stuff on to the SD card and then transferring the data from there to the computer.
I had booted in safe mode, but there too the phone showed same behavior. I also noticed that the home button, or the task manager button were not working too.
After taking the backup, I also changed the password for the Gmail account for security, in case the mobile was somehow compromised.
Then I wanted to do a factory reset, but the button seems to be greyed out, and there seems to be no way to perform a soft factory reset. So, your post comes at the nick of time to save me, as I was thinking what to do now. Thanks a ton!

Performed a hard reset of the phone, and the phone is working fine now. Everything is normal.
What might be the reason for such behavior though?
Not being able to lock the phone, install/update apps, factory reset... all this makes me think if it was some kind of malware.
Another reason I can think of is that the storage got full, and so these strange stuff started, but it should go back to normal when stuff was deleted and sufficient storage became available. Still, doesnt explain why lock wouldn't remain.... and other stuff. Really weird.

Modern,"Smart Phones" are very complex computers.With so many apps on them that get updated some updates don't always play nice and mess up the phones.You could spend hours tracking down a single app that might be a cause of a problem.
As you say as well the the storage on the phones might well have got clogged up with old Temporary data that has not been cleared out as it should.
For future reference another trick is to wipe the Cache partition from Recovery mode.I would have suggested this first but as you said space was running out it's best to have a clean start

Yes, it was good to have a clean start with the phone.
Thank you for that trick to wipe the cache partition from Recovery mode. Will keep that in mind.
Thanks a lot again.

Help! S7 Now Asking for Startup Password

Hi All,
Apologies for in advance for what may be a long post but I want to give as much information as possible in case anyone might be able to help.
So about 3 years ago I purchased a Samsung S7 (GM-G930f) from a phone shop. The device was rooted. This hadn't really caused any issues until today. The phone was overheating and losing it's charge very quickly. I downloaded Malwarebytes & AVG separately and did a scan with both.
One of them suggested turning off developer mode and a setting in it due to a security issue. (An OEM setting I think)
So I turned this off. A short while later the battery died. When I went to charge and turn the phone back on I got a message saying 'Custom binary locked by FAP Lock'.
After a bit of researching it seemed I had to reflash the firmware to the device. I got the most recent version from Sammobile and installed it using Odin. I used the "Home CSC" file in an effort to retain the data on the phone.
So that all seemed to work but the phone is now asking for a password- "Your phone is encrypted for security. To start up your device enter your password"
We have no clue what this password is- have tried the google account password and the samsung account password but no luck. I also logged on to the Find My Phone section on Samsung which was suggested on a couple of websites, however the device needs to be connected to a network before this service is of any use.
Is there any way at all I can retrieve the data from the phone without having to perform a factory reset? I am by no means a developer but am tech savvy and can follow clear instructions. There are recent photographs of immense sentimental value on the phone.
Also I am not some thief trying to hack into a phone. It is my partners phone and she has had it for 3 years.
Any help at all would be greatly appreciated

Type (default_password) without brackets obviously, if it doesn't work root the phone with Odin and see if it's starts normally.
Also do you know if you changed photo storage to sd card? If so you can remove it and see what's pics are stored there under folder DCIM. A firmware restore does nothing to the sd card.

hey- thanks for getting back to me. Yeah I've checked the sd card already- unfortunately it was saving to the phone it seems! Just tried that password and no luck.
Will rooting the phone with Odin wipe the data? I'll have to look up how to do it so I don't mess it up!
Thanks again

No rooting won't wipe. Use cf auto root
