After you failed numerous times, doesn't the phone give you the option to log in your google account and reset the passcode?

If you haven;t log into your google account in the phone (you go to play.google.com, and use the Android device manager to change your passcode, or enter the code wrong many times and it will let you have an option to reset by your gmail).
Or if you don't have adb debugging enable or someway to access it, there is no way except factory reseting.

How in earth you forget your code and can't log into the google account?
You aren't using someone elses phone are u?

Install adb, connect your phone to your PC, then use the command "adb devices". If a device code is listed, then it's enabled.

Nexus 7 too many pattern attempts Locked!

I got my N7 Last week. My sister Locked it by too many pattern attempts. Now it asking to enter my gmail username and password.. I entered it bt not worked. I googled and find for solutions. I dint get a working solution.
Then i tried to Hard Reset the device. I followed all instructions given by google. But it freezes while Going through Recovery mode. I waited about Hours for a response. after that I tried Hard Reset by connecting USB Cable to PC. It Freezes at the menu itself.
Then I Installed SDK (4.1), ADB, FASTBOOT and Drivers from Nexus 7 toolkit by XDA.. still not working..
please Help Me to Solve this.
My device is UNROOTED.
Wi-Fi is OFF!
USB DEBUGGING is OFF!
I cant acces non of above because its locked.. please please help!
Finally got it!
When I Installed the drivers and Rebooted my device the Hard reset Worked Finely.
Ensure that..
1. USB Cable plugged in or not.
2. Necessary drivers installed or not.
That is funny because that's exactly what happened when I had my og droid. Except I was the one who locked myself out of my phone. Good job on getting this resolved.

Google Nexus 7 Tab unlock
Hi ,
Tried so But failed to unlock my tab..its so painfull and very sad to state that google has no support..Can you help me out with step by step process to unloack my nexus 7 tab from " too many patterns tried "
thx
Sounds like Google should have put some more thought in the feature. Give the users a way to lock themselves out - and they will.
At least the "too many attempts" screen should tell the user to log in with the Google ID and password the device was registered with.
Can't help but think... Stolen.
Geesh, isit so hard Tod remember Gmail info so you can back in?

[Q] I9505 Help Needed ADB

Hi, I have a S4 i9505 with a problem, screen broken and no display at all + usb debugging is disabled.
Phone: Not rooted, original software, usb debugging disabled, no display at all
What I want to achieve: restore all my photos / videos on the phone memory, no sd card
What I have attempted:
installed ADB & fastboot based on instructions from http://forum.xda-developers.com/showthread.php?t=2786395
What I need help with:
- When i try to get into recovery mode, i wasn't sure if i am indeed in there since i can't see anything, but in total there's a vibration when i turn on the phone, and another vibration when i release the power up+power+home after pressing them down for about 5 seconds.
- When in command prompt I type adb devices and there was none, and when i type adb shell it says error: device not found
I have ensured all drivers for my phone are installed (even with PdaNetA4180 & UniversalAdbDriverSetup6 from cynanogen) but the error remains. refer to attached image.
I have done extensive search on the forum but still couldn't find any ways to get usb debugging enabled on my crippled phone.
Any step by step guide would really be helpful! Thanks
Ps. Main problem = device not found in adb , usb debugging disabled, screen no display/cracked
What do you want? To recover files? To my knowledge that is not possible.
You would first need to flash a custom recovery for adb to work in recovery.
Then you would need to allow the connection on your device (which you can't do).
Yes I need to recover photos only. Nothing else.
Please kindly guide the steps on how to flash a custom recovery (w/o control of the phone's display or touch)
Thanks.
Your device is shown connected in windows
Why not use the mtp protocol and copy whatever you want
Hi, in the beginning, my phone is locked with a pattern pin.
I read the tutorials and managed to get away with the pattern pin by resetting my phone to factory settings via recovery mode i guess by watching youtube guide.
I didn't knew the photos and all will get deleted off from it, so there's nothing to transfer over when i got MTP working and able to access files inside the phone.
What do you recommend? Would fixing the screen and then using dr fone recovery works? or is there any other way to solve this without getting the phone display fixed? Thanks.
If the photos are deleted by the factory reset then i am sorry to day but you cannot recover them even if you get the screen fixed

locked lg g2

Hi. I had a pin unlock for my phone. I forgot it and entered it too many times. Now it wants me to unlock via my google account which is totally fine...but my phone wasn't connected to WiFi or mobile data wasn't enabled.
So even though I enter the correct details the phone cannot verify them!
I went unto Android device manager and tried to reset the lock screen but it failed to work.
I don't want to do a factory reset as I have not got some recent (and really quite important!) photos backed up! What do I do?
I tried to use a USB cord connected to my phone and PC but because the phone is locked only sleep and charge works.
Please help! Gracias

Recover data from S8 with broken screen

Hi everyone!
I broke my S8 screen completely by dropping it (the phone is still working, not know if the touch still works).
I want to recover WhatsApp backup folder and DCIM folder (i had no backup service enabled, nor samsung account, nor google photo or gdrive), so i thought to go ahed through ADB. Anyway adb list no devices until i unlock my phone through pattern code ( i had no facial/retina/fingerprint mode set).
So i thought to proceed through download mode, flash twrp through odin and access adb through twrp. Anyway it looks like i cannot use odin to flash until i trigger on "OEM Unlock" in developer options which i can't do no more cause of the broken screen.
Is there another way to enable OEM Unlock which doesn't require touch input? Or is there any other way to recover my two folders?
A big thanks for everyone who could help
You can use an otg adapter and a mouse and try to replicate your pattern code and after your in just transfer your files. If you happen to have a second cell phone I would suggest you practise a bit on that screen first so you can replicate the exact movements to unlock your phone. Had an issue with my s6 edge and that worked like a charm.

If you don't know how to recover data from S8 phone, just use an Android data recovery software, it can help you recover data from an broken Android device, it is really simple to finsih the recovery process. And you can preview and recover the data from your broken phone, so that you don't lose these data.

Log into Samsung Find my mobile. Use your Samsung Account details to log in.
There you will see alot of options that you can perform on your Galaxy S8 remotely.
Use the remotely unlock my device option to unlock your device.
Then connect your phone to the Laptop or PC using data cable and recover the data.
Hope it helps.

Recover Files from Nexus 6P Bootloop w/ USB Debugging Locked

Hello!
My nexus 6P is stuck in a bootloop and I need to get my photos from the internal storage. I am unable to enter recovery mode; when I try to enter recovery mode, the device just goes back to the Google logo. Is there a way to recover my files even if USB debugging is not enabled and my device is not rooted?
Thank you!
Is your bootloader unlocked? If it is then you should be able to flash one of the kernels from here: https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279 and it'll allow your phone to boot up completely so you can transfer data from your phone to your computer.

How could I know if my bootloader is unlocked? But I think it's locked since I don't remember unlocking it.
While your 6P is turned off hold volume down and press the power key to turn it on. This will put the phone into fastboot mode and from there you can look at the text towards the bottom of the screen. If it says: Device is UNLOCKED then the bootloader is unlocked and you can flash one of those kernels. If it says: Device is LOCKED then your bootloader is locked and you will not be able to pull the info off of your phone.

It says that device is locked. So this means that there is no way to retrieve the files on my phone? Or is it possible to physically open the device then get the internal storage and access it somehow?
The only other way you might be able to get the data off your phone is to get the SoC re-soldered on so that it'll stop bootlooping, but I'm not entirely sure this will work. Other than that I don't think there's any other way to get your data.

Because you are bootloader locked, the workaround of flashing a custom kernel is not available to you. In order to flash a kernel you need to be unlocked, but the process of unlocking your bootloader WILL WIPE your phone and all your data will go with it. There are threads talking about using a hairdryer to heat up the phone before powering it on to put it in limp mode. If you can get your phone to boot up, you can enable USB Debugging under Developer Settings and then try to get your files off, but chances are extremely unlikely because you have to keep the phone hot to prevent it from bootlooping again. Opening the phone to access the memory chips is a non-starter. Lastly, are you absolutely positive that your photos are not automatically uploaded to Photos? Have you accessed (logged into) Google photos and verified they are not there?
Help! I'm in the same situation!

If your bootloader is locked and you don't have usb debugging enabled there is not much you can do. Have you logged into Google photos on your PC to verify your photos are not there? If your data/photos are not the issue and you just need your phone working again, there is another thread on how to do that (with a little luck).
Hi Guys,
I have gone through your messages. In my case bootloader is locked but USB debugging is ON. Also I checked google photos. Some photos are there but camera and whatsapp photos are not there. May I know any work around to get the data ?

Drop down to the stock recovery mode and use adb to pull files to your PC. If you have TWRP recovery installed you can just use MTP to drag and drop files. Photos are located in /sdcard/DCIM/Camera. WhatsApp photos are in /sdcard/WhatsApp/Media.
I have exact same problem as OP and my phone is Locked and I don't remember enabling debugging mode. From reading replies I understand I can't get my data in internal storage. Now what should I do to make my phone boot-up. I don't need my data back. Also I'm confused about flashing Factory image vs flashing OTA. What does the two mean and what should I do?

Have you found a way to recover phone the phone from bootlooping. As i'm facing the similar problem, when I try to boot into recovery, it starts bootlooping, and I can't use that hairdryer method as there is no OS installed in my phone, and top of that, my bootloader locked too...

Sorry, but if you have no OS, and bootloader locked, and bootlooping you are dead in the water. My phone was unlocked so I was able to use the 4-core method. If your new phone is a Google product, unlock the bootloader from day one.
