[Q] Nexus 5 wipes itself without asking - Nexus 5 Q&A, Help & Troubleshooting

Hi,
I have a nexus 5 since April 2014, and since then it has wiped itself 3 times without my permission (once in July, and recently in Sept and Oct). Maybe since kitkat upgrade ?
Always the phone was on the table and screen locked with PIN - so this isn't a case of accidentally selecting factory reset.
Also, no remote wipe command was sent.
I discovered the reset while picking up the phone to use it and seeing the famous robot screen with the text "erasing data".
Has anyone encountered this issue and how to prevent it?
Also, does anyone know if once the erasing process starts how to interrupt / reverse it?
This isn't a case of a email hack as I have 2 step verification and remote wipe not possible as the phone was not connected to WiFi or cell data network at the time.
Does anyone know how a factory reset can occur aside from selecting from the menu or remote wipe?
Also phone is stock no root, etc..

When you refer to remote wipe, I assume you are referring to Android Device Manager. But there are other apps that could do this, like Cerberus. Do you have any other security apps installed?

Hi,
Yes I'm referring to ADM. The first time it happened I had Mobile Iron installed. The other 2 times I made sure not to install that app. So no security apps at all except maybe exchange email account that probably allows remote wipes, but I viewed the logs on my exchange account for wipes sent and no such command was sent.
Also, I have 2 iOS devices that are on mobile iron and exchange for over a year and no wipes occurred.

[Q] Android Smartphone Security

Correct me if I'm wrong...
Do you think now a days these android smart phones are secured?
A. If anyone stoles my phone they are smart enough to do hard reset by googling and wipe all the datas on the phone. So no track!
B. IMEI is another pain in the neck! No proper service is there yet to track over online or offline for common people!
C. Anyone can just go to my phone's settings while unlocked and give a soft touch over the option called: Factory data reset! All gone!!!
Even decade ago feature phones (When Android was no where around) also used to come with a security option where Factory reset used to be protected with a password apart from screen lock.
Why no development in this segment???
A. Do you know any device which can prevent this? I think it's good enough that your data has to be cleared.
B. I think this can be avoided by just throwing away the sim card.
C. No idea on this point but there should be a password.

Phone reset after consecutive failed authentication

Hello,
My phone is protected using fingerprint scans and pin code. I noticed that after several failures the phone is not only telling me that it will lock, but also that it will reset (after 8 failures, or something like that).
I don't see that as a security feature, anyone willing to make me loose a lot of time only have to put his/her fingers 8 times on the button and ... everything is gone in my phone ?
Is this a local security feature ? I mean is it configurable somewhere ? or is coming from a remote policy, or hardcoded somewhere in the phone ?
Thanks.
Did you add your work email? I had this when I synched my work email to my device. Apparently, this is one of the security policies of my workplace.
And yes, I was locked out of my device a few days after I got it. It read my belly as a "fingerprint" unlock attempt, and soon I just saw it was wiping all my data. I was really bummed by that since it took hours for me to set up my device according to my liking. Fortunately, I still had my previous phone and didnt wipe it yet.
Yes, I have a work mail configured. Do you think it comes with security policies ? Because on our other phones (iphone, GS5/6) there is no similar settings put in place to wipe data.

Mate 9 factory reset itself without any reason

Hi everyone,
My device hard reset itself without any reason. I was walking outside and listened to a podcast through headphones when suddenly sound stopped. When I pull the phone out of the pocket I saw recovery screen “Low-level factory reset” and after a while, everything I had had on the phone before was just gone. I don’t remember that any other piece of human engineering made me so upset.
So, I didn’t touch my phone and it was offline (data disabled and no wifi around). It had MHA-L29C567B167 firmware and was rooted by this guide and then TWRP was replaced by the standard recovery (which probably made this hard reset possible). I haven’t done anything system related with the phone during last several weeks.
Did anyone else have the same problem? Do you have any ideas why the phone did it?
I had the same reset, when backup password on lockscreen (normally fingerprint) was filled in wrongly about nine times in succession.
Rogue app running as root? *shrug*
So frustrating
I had the same issue sooooo many times... The only way I found to stop this is to remove the password... I do open apps and all whilst the phone in my pocket... But at least it doesn't factory reset!!!!
so it happens after you input incorrect passwords after x amount of times?
Yes. After nine or ten times a wrong password, it did the factory reset. It happened due to a connected Bluetooth keyboard that wasn't turned off with key pressed for a long time by accident.
To prevent this problem​ from happening again I left TWRP flashed to the recovery partition. Now if the system requests recovery to factory reset TWRP will just ignore it.
Also, I found out that having Microsoft Outlook installed makes the problem worse. It reduce the number of incorrect PIN enter attempts. E.g. despite the fact that it displays "You have 4 more attemps" the device tries to factory resset.
I have these hard reset on me 3 times over the last 7 months. And 2 of these times, were happened when I was oversea. All my data are gone after it reset, and what make it worst was that I was oversea, and the 1st restoration process asked for WIFI setup & connection. Common, you are a foreign land on roaming (even with data), they still insist you need a WIFI connection before the restoration can continue.... a very frustrated experience especially you are oversea, and it happened to me twice with the most recent case - 2 days ago.... So, how do I activate TWRP?

(Solved) Cannot Sign Into Older, Factory-reset Device: "Unable to sign in due to unknown error..."

[Edit: Just a quick note to let folks know, if there was anyone who cared at all, that this issue has resolved itself. I have no real understanding why, but I did a few more "Factory Resets", both with "Wipe Userdata and Personalizations" and with just "Wipe Userdata". Whatever I did just seemed to work as my wife was able to sign in afterwards. When she did I removed her account from the phone, did the multi-wipe procedure again and was able to sign in as myself. That was the goal.
Thanks very much, again, to the folks who commented on my question!]
Hey All,
I have an older device, a Moto X Pure, that I've done the factory reset/wipe all data thing via the stock Recovery. The device is on the latest update that Moto provided 3 (or is it now 4) years ago now, Android 7.1. Other than an unlocked bootloader, everything else is on the device is stock and unrooted, although it does not have a SIM card installed in it at this time. In fact, the entire reason that I'm trying to initialize it is to test a number of different mobile service providers to find the best provider for my, largely rural, common travel pathways.
However, once I enter my wifi info successfully and try to sign into this device with my Google ID/password, I cannot do it. Instead I get an error message that starts with the text that's in quotes in the post subject. The message continues with "try another account, or wait 24 hours and try again." Now, I've done the 24-hour wait thing several times, but the result is the same.
The phone was my wife's daily driver until I replaced it a couple of months ago. I've had her try to sign into it as well, but she can't do it either with the identical result.
So I'm at my wit's end. Has anyone in this sphere ever encountered this error? Were you able to overcome it? Can any other kind soul here suggest a way to circumvent this? I mean one that doesn't involve sledge hammers and concrete pads?
Thanks!
cheers,
john
My guess is problems like reported could be related to Factory Reset Protection, which happens when the previous owner of a device didn't properly remove his/her Google account from phone prior to doing a factory reset.

If his wife did a factory reset when she first got it then that's not the case.
OP, did she?
jwoegerbauer, how is the reset password handled? If you originally sign in to the device with one password but then change your Google account password, does the device authorization automatically update too?
Or do you use the original password?
Any failsafe to prevent the device owner from getting permanently locked out?
That whole embedded subsystem gives me a headache.
Thanks to both of you for the feedback on this!

Ah, yeah, that definitely happened. By that I mean that the previous owner did not properly remove their account prior to my doing the factory reset.
Now the question is: Is there any way for me to recover from this situation? I have the latest factory ROM for this device (from three or four years ago). Can I just flash that over what's on there? Or have I tripped some kind of circuit breaker and I'm just hosed?

No, and we bought it on Swappa about six months after it came out, with an unlocked bootloader no less, so we just assumed that the seller did a reset before transferring it to us, but we don't know that definitively.

Yes, same questions now that blackhawk mentions them. (Since I didn't think to ask such good ones myself!)

8T Android 13 factory reset issues - WiFi

Hey all,
I upgraded to 13 when it was released in the US... Oddly no issues. 5 days ago I did a factory reset on the device now the issues start.... I can connect to WiFi outside of enterprise (home network, hotspots etc...) without issues, Enterprise wifi is a totally different story.... The system i am trying to connect to is PEAP MSVCHAPv2...
On the device it gives me a Timed out on the log server for wifi im getting
TLS Handshake failed in SSL_read with error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate
eap-tls: Error in establishing TLS session
Reset all of the network connects re-reset to factory and installed the cert from the wireless.... still no luck.. any ideas?
Can you share the certificate? It may be the problem
The cert isn't on my phone. Not being pulled down. Even when I was on 12 it was setup to use system certs and not verify.

Seems to be some kind of incompability with your enterprise and Android13.

That's what I be was afraid of...Aruba and Android 13 not happy with each other... I am guessing there was enough Android 12 was still in cache after upgrade that allowed it to work... But died after factory reset
I had a weird issue where after upgrading I couldn't click next, after selecting start(welcome screen) and gets stuck in a boot loop when I press screen touches excessively.. or left idle for 30 seconds. Had to factory reset, I couldn't find a way to clear cache as I don't think it's dalvik. Isn't it art?
Anyway. Annoying bug.
