Mate 9 factory reset itself without any reason - Huawei Mate 9 Questions & Answers

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?

Touch Pro constantly soft resetting itself (3 Aust)

Hi Guys,
I've been an owner of a Three-branded HTC Touch Pro in Australia for over a year now, with no major issues with it except for the multitude of WM bugs and lagginess I've grown to accept.
A year ago I loaded SPB Mobile Shell and I have a couple of other apps but not many that I use frequently. The phone is mainly used for calls, messaging, syncing with my Outlook calendar and contacts, and browsing the internet
A day ago the phone began behaving very strangely, with no rational explanation as to the trigger or cause.
The phone has begun randomly and frequently soft resetting itself. This can occur when I'm in the middle of writing a text message, on a call, or browsing the internet (or whilst doing anything else, really). The phone will go blank, the vibrator will vibrate once, then the 'Touch Pro' logo welcome logo will be displayed as it reboots.
The phone will then either:
(A) wait for me to enter my PIN
or
(B) go straight past the PIN screen through to the home screen
If I do not enter my PIN after this (either at the PIN screen or by invoking the PIN screen by selecting the Phone app), the soft-resetting issue doesn't occur. However, this leaves me with a useless brick, unconnected to any networks.
So I have to enter my PIN and then wait for the device to mysteriously and randomly soft reset itself at some point soon. Extremely frustrating.
Interestingly, I've found that the soft resetting issue doesn't occur when the device is plugged into the mains power or to a computer.
Today I upgraded the ROM to the latest available on the 3 website, and then installed the latest version of Mobile Shell 3.5. However the issue still persists...
I've now managed to disable the PIN request so that when the soft resetting occurs, the phone is automatically reconnected to the network but I'm not sure what sort of never ending loop of resetting this will create!!
Any clues???
So as a follow-up to this issue, my phone appears to have mysteriously fixed itself.
It is no longer resetting itself... or at least I haven't witnessed it reset itself.
Could anyone provide a potential analysis of what's going on??

Things like this happen for a few reasons, A bad flash, Corrupt blocks in the memory, and even if the device gets too hot, if it happens again i suggest you use a tty program like mtty of putty to format your device before flashing a new rom

[Q] Nexus 5 wipes itself without asking

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.

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.

Strange wifi crash - reboot

So been running c59 Android 11 for a couple of weeks. All working pretty well when today i noticed my device was not on Wifi..
I went to wifi settings the phone locked up and crashed - rebooted.
Same thing is occuring except now i have a little Sim icon and an X in where the celluar signal is.
I still can recieve calls though no network access at all!
Just tried aeroplane mode and now its stuck and i cannot turn off aeroplane mode..
tried the reset network settings.. no change..
this phone is rubbish.
looks like another factory reset coming up...
just for anyone else who has this issue. you need to Format Data through recovery.. you lose everything. this fixed it for me.
You lose nothing because people are supposed to BACKUP their stuff.
Smartphones haven't been around since only a few weeks ago, it shouldn't come as a surprise that at some point they can fail or like in this case for some reason need a formatting.

If you think about it you should be able to format Application Data only and not lose your photos etc..
Even my old Nexus 4 from 9 years ago can do that..
actually every phone i have ever had could do that other than this one.
Why would the existence of personal photos cause a phone not too boot? So why would the manufacturer make you format them to reset the phone?
Just a poorly designed device really..
And for the record i did backup and do backup. Though i wanted to inform others who may have to perform this fix that they will lose data.

Data recovery from encrypted Nokia 6.1

TL;DR - Phone will not accept correct encrypt password. Need to dump data partition to computer and decrypt from there, or something like that.
So I have a Nokia 6.1 from 2018 that I used for just about a year. I upgraded to a nicer phone during summer 2019, at which point I transferred all the data I thought I needed, turned the power off, put the phone on a shelf and forgot about it for many months. I remember when I last powered it down, the battery was fully charged. Quite some time later I realized I needed to retrieve some important data written down in an old OneNote account that was synced with that phone and nothing else. Upon logging in, I discovered Microsoft had wiped the account clean due to an extended period of inactivity, meaning the only copy of that data now exists on that phone and nowhere else.
When I dug out the phone and tried to power it up, the battery was completely flat. I plugged it in and it booted up okay, but it would not accept the passphrase to unlock. I can only assume this is due to some sort of bug in Android (I believe it is running 9 Pie, but I don't remember for certain), as I know for a fact the password is correct. I've been putting off trying to unlock this thing for over a year now, but it needs to be done. I've noticed over my several attempts to enter the password that the phone has been behaving somewhat erratically. For example, it doesn't always respond to the power button right away. I'll try to press it again, and the screen will blink on and off several times. Also, when I first tried to unlock the phone, I could enter the passphrase as many times as I wanted, but now when I try, it locks me out for 30 seconds after each attempt, and also notifies me of the total number of failed attempts. When I reboot the phone, the failed attempt counter resets to zero.
Do I have any recourse here? Since I know the passphrase, is it possible to dump the encrypted data partition to my computer and decrypt it from there? The phone is not rooted, nor does it have any custom ROMs or anything like that. I appreciate any help anyone can give.
Quick addendum, I attempted to sideload the final OTA update sourced from the Nokia OTA Repository on Telegram onto the phone via recovery mode. It is running Android 10 now but still no luck unlocking. Interestingly, however, the failed attempt counter now appears to be working correctly, indicating I have entered the incorrect passphrase 31 times now. I'm not sure how many more times I can do that before it wipes everything.
